Solving The Electrification Conundrum
The title of this post, is the same as an article in the July 2021 Edition of Modern Railways.
This is the introductory sub-heading.
Regional and rural railways poses a huge problem for the railway to decarbonise.
Lorna McDonald of Hitachi Rail and Jay Mehta of Hitachi ABB Power Grids tell Andy Roden why they believe they have the answer.
These are my thoughts on what is said.
Battery-Electric Trains
The article starts by giving a review of battery-electric trains and their use on routes of moderate but important length.
- Some short routes can be handled with just a charge on an electrified main line.
- Some will need a recharge at the termini.
- Other routes might need a recharge at some intermediate stations, with a possible increase in dwell times.
It was in February 2015, that I wrote Is The Battery Electric Multiple Unit (BEMU) A Big Innovation In Train Design?, after a ride in public service on Bombardier’s test battery-electric train based on a Class 379 train.
I also wrote this in the related post.
Returning from Harwich, I travelled with the train’s on-board test engineer, who was monitoring the train performance in battery mode on a laptop. He told me that acceleration in this mode was the same as a standard train, that the range was up to sixty miles and that only minimal instruction was needed to convert a driver familiar to the Class 379 to this battery variant.
It was an impressive demonstration, of how a full-size train could be run in normal service without connection to a power supply. I also suspect that the partners in the project must be very confident about the train and its technology to allow paying passengers to travel on their only test train.
A couple of years later, I met a lady on another train, who’d used the test train virtually every day during the trial and she and her fellow travellers felt that it was as good if not better than the normal service from a Class 360 train or a Class 321 train.
So why if the engineering, customer acceptance and reliability were proven six years ago, do we not have several battery electric trains in service?
- There is a proven need for battery-electric trains on the Marshlink Line and the Uckfield Branch in Sussex.
- The current Class 171 trains are needed elsewhere, so why are no plans in place for replacement trains?
- The government is pushing electric cars and buses, but why is there such little political support for battery-electric trains?
It’s almost as if, an important civil servant in the decision process has the naive belief that battery-electric trains won’t work and if they do, they will be phenomenally expensive. So the answer is an inevitable no!
Only in the South Wales Metro, are battery-electric trains considered to be part of the solution to create a more efficient and affordable electric railway.
But as I have constantly pointed out since February 2015 in this blog, battery-electric trains should be one of the innovations we use to build a better railway.
Hydrogen Powered Trains
The article says this about hydrogen powered trains.
Hybrid hydrogen fuel cells can potentially solve the range problem, but at the cost of the fuel eating up internal capacity that would ideally be used for passengers. (and as Industry and Technology Editor Roger Ford points out, at present hydrogen is a rather dirty fuel). By contrast, there is no loss of seating or capacity in a Hitachi battery train.
I suspect the article is referring to the Alstom train, which is based on the technology of the Alstom Coradia iLint.
I have ridden this train.
- It works reliably.
- It runs on a 100 km route.
- The route is partially electrified, but the train doesn’t have a pantograph.
- It has a very noisy mechanical transmission.
Having spoken to passengers at length, no-one seemed bothered by the Hindenburg possibilities.
It is certainly doing some things right, as nearly fifty trains have been ordered for train operating companies in Germany.
Alstom’s train for the UK is the Class 600 train, which will be converted from a four-car Class 321 train.
Note.
- Half of both driver cars is taken up by a hydrogen tank.
- Trains will be three-cars.
- Trains will be able to carry as many passengers as a two-car Class 156 train.
It is an inefficient design that can be improved upon.
Porterbrook and Birmingham University appear to have done that with their Class 799 train.
- It can use 25 KVAC overhead or 750 VDC third-rail electrification.
- The hydrogen tanks, fuel cell and other hydrogen gubbins are under the floor.
This picture from Network Rail shows how the train will appear at COP26 in Glasgow in November.
Now that’s what I call a train! Let alone a hydrogen train!
Without doubt, Porterbrook and their academic friends in Birmingham will be laying down a strong marker for hydrogen at COP26!
I know my hydrogen, as my first job on leaving Liverpool University with my Control Engineering degree in 1968 was for ICI at Runcorn, where I worked in a plant that electrolysed brine into hydrogen, sodium hydroxide and chlorine.
My life went full circle last week, when I rode this hydrogen powered bus in London.
The hydrogen is currently supplied from the same chemical works in Runcorn, where I worked. But plans have been made at Runcorn, to produce the hydrogen from renewable energy, which would make the hydrogen as green hydrogen of the highest standard. So sorry Roger, but totally carbon-free hydrogen is available.
The bus is a Wightbus Hydroliner FCEV and this page on the Wrightbus web site gives the specification. The specification also gives a series of cutaway drawings, which show how they fit 86 passengers, all the hydrogen gubbins and a driver into a standard size double-deck bus.
I believe that Alstom’s current proposal is not a viable design, but I wouldn’t say that about the Porterbrook/Birmingham University design.
Any Alternative To Full Electrification Must Meet Operator And Customer Expectations
This is a paragraph from the article.
It’s essential that an alternative traction solution offers the same levels of performance and frequency, while providing an increase in capacity and being economically viable.
In performance, I would include reliability. As the on-board engineer indicated on the Bombardier test train on the Harwich branch, overhead electrification is not totally reliable, when there are winds and/or criminals about.
Easy Wins
Hitachi’s five-car Class 800 trains and Class 802 trains each have three diesel engines and run the following short routes.
- Kings Cross and Middlesbrough- 21 miles not electrified – Changeover in Northallerton station
- Kings Cross and Lincoln – 16.6 miles not electrified – Changeover in Newark Northgate station
- Paddington and Bedwyn – 13.3 miles not electrified – Changeover in Newbury station
- Paddington and Oxford – 10.3 miles not electrified – Changeover in Didcot Parkway station
Some of these routes could surely be run with a train, where one diesel engine was replaced by a battery-pack.
As I’m someone, who was designing, building and testing plug-compatible transistorised electronics in the 1960s to replace older valve-based equipment in a heavy engineering factory, I suspect that creating a plug-compatible battery-pack that does what a diesel engine does in terms of power and performance is not impossible.
What would be the reaction to passengers, once they had been told, they had run all the way to or from London without using any diesel?
Hopefully, they’d come again and tell their friends, which is what a train operator wants and needs.
Solving The Electrification Conundrum
This section is from the article.
Where electrification isn’t likely to be a viable proposition, this presents a real conundrum to train operators and rolling stock leasing companies.
This is why Hitachi Rail and Hitachi ABB Power Grids are joining together to present a combined battery train and charging solution to solve this conundrum. In 2020, Hitachi and ABB’s Power Grids business, came together in a joint venture, and an early outcome of this is confidence that bringing together their expertise in rail, power and grid management, they can work together to make electrification simpler cheaper and quicker.
I agree strongly with the second paragraph, as several times, I’ve been the mathematician and simulation expert in a large multi-disciplinary engineering project, that went on to be very successful.
The Heart Of The Proposition
This is a paragraph from the article.
The proposition is conceptually simple. Rather than have extended dwell times at stations for battery-powered trains, why not have a short stretch of 25 KVAC overhead catenary (the exact length will depend on the types of train and the route) which can charge trains at linespeed on the move via a conventional pantograph?
The article also mentions ABB’s related expertise.
- Charging buses all over Europe.
- Creating the power grid for the Great Western Electrification to Cardiff.
I like the concept, but then it’s very similar to what I wrote in The Concept Of Electrification Islands in April 2020.
But as they are electrical power engineers and I’m not, they’d know how to create the system.
Collaboration With Hyperdrive Innovation
The article has nothing negative to say about the the collaboration with Hyperdrive Innovation to produce the battery-packs.
Route Modelling
Hitachi appear to have developed a sophisticated route modelling system, so that routes and charging positions can be planned.
I would be very surprised if they hadn’t developed such a system.
Modular And Scalable
This is a paragraph from the article.
In the heart of the system is a containerised modular solution containing everything needed to power a stretch of overhead catenary to charge trains. A three-car battery train might need one of these, but the great advantage is that it is scalable to capacity and speed requirements.
This all sounds very sensible and can surely cope with a variety of lines and traffic levels.
It also has the great advantage , that if a line is eventually electrified, the equipment can be moved on to another line.
Financing Trains And Chargers
The article talks about the flexibility of the system from an operator’s point of view with respect to finance.
I’ve had some good mentors in the area of finance and I know innovative finance contributed to the success of Metier Management Systems, the project management company I started with three others in 1977.
After selling Metier, I formed an innovative finance company, which would certainly have liked the proposition put forward in the article.
No Compromise, Little Risk
I would agree with this heading of the penultimate section of the article.
In February 2015, when I rode that Class 379 train between Manningtree and Harwich, no compromise had been made by Bombardier and it charged in the electrified bay platform at Manningtree.
But why was that train not put through an extensive route-proving exercise in the UK after the successful trial at Manningtree?
- Was it the financial state of Bombardier?
- Was it a lack of belief on the part of politicians, who were too preoccupied with Brexit?
- Was it that an unnamed civil servant didn’t like the concept and stopped the project?
Whatever the reason, we have wasted several years in getting electric trains accepted on UK railways.
If no compromise needs to be made to create a battery-electric train, that is equivalent to the best-in-class diesel or electric multiple units, then what about the risk?
The beauty of Hitachi’s battery-electric train project is that it can be done in phases designed to minimise risk.
Phase 1 – Initial Battery Testing
Obviously, there will be a lot of bench testing in a laboratory.
But I also believe that if the Class 803 trains are fitted with a similar battery from Hyperdrive Innovation, then this small fleet of five trains can be used to test a lot of the functionality of the batteries initially in a test environment and later in a real service environment.
The picture shows a Class 803 train under test through Oakleigh Park station.
This phase would be very low risk, especially where passengers are concerned.
Phase 2 – Battery Traction Testing And Route Proving
I am a devious bastard, when it comes to software development. The next set of features would always be available for me to test earlier, than anybody else knew.
I doubt that the engineers at Hyperdrive Innovation will be any different.
So I wouldn’t be surprised to find out that the batteries in the Class 803 trains can also be used for traction, if you have the right authority.
We might even see Class 803 trains turning up in some unusual places to test the traction abilities of the batteries.
As East Coast Trains, Great Western Railway and Hull Trains are all First Group companies, I can’t see any problems.
I’m also sure that Hitachi could convert some Class 800 or Class 802 trains and add these to the test fleet, if East Coast Trains need their Class 803 trains to start service.
This phase would be very low risk, especially where passengers are concerned.
Possibly, the worse thing, that could happen would be a battery failure, which would need the train to be rescued.
Phase 3 – Service Testing On Short Routes
As I indicated earlier, there are some easy routes between London and places like Bedwyn, Lincoln, Middlesbrough and Oxford, that should be possible with a Class 800 or Class 802 train fitted with the appropriate number of batteries.
Once the trains have shown, the required level of performance and reliability, I can see converted Class 800, 801 and Class 802 trains entering services on these and other routes.
Another low risk phase, although passengers are involved, but they are probably subject to the same risks, as on an unmodified train.
Various combinations of diesel generators and batteries could be used to find out, what is the optimum combination for the typical diagrams that train operators use.
Hitachi didn’t commit to any dates, but I can see battery-electric trains running on the Great Western Railway earlier than anybody thinks.
Phase 4 – Service Testing On Medium Routes With A Terminal Charger System
It is my view that the ideal test route for battery-electric trains with a terminal charger system would be the Hull Trains service between London Kings Cross and Hull and Beverley.
The route is effectively in three sections.
- London Kings Cross and Temple Hirst junction – 169.2 miles – Full Electrification
- Temple Hirst junction and Hull station – 36.1 miles – No Electrification
- Hull station and Beverley station – 8.3 miles – No Electrification
Two things would be needed to run zero-carbon electric trains on this route.
- Sufficient battery capacity in Hull Trains’s Class 802 trains to reliably handle the 36.1 miles between Temple Hirst junction and Hull station.
- A charging system in Hull station.
As Hull station also handles other Class 800 and Class 802 trains, there will probably be a need to put a charging system in more than one platform.
Note.
- Hull station has plenty of space.
- No other infrastructure work would be needed.
- There is a large bus interchange next door, so I suspect the power supply to Hull station is good.
Hull would be a very good first destination for a battery-electric InterCity train.
Others would include Bristol, Cheltenham, Chester, Scarborough, Sunderland and Swansea.
The risk would be very low, if the trains still had some diesel generator capacity.
Phase 5 – Service Testing On Long Routes With Multiple Charger Systems
Once the performance and reliability of the charger systems have been proven in single installations like perhaps Hull and Swansea stations, longer routes can be prepared for electric trains.
This press release from Hitachi is entitled Hitachi And Eversholt Rail To Develop GWR Intercity Battery Hybrid Train – Offering Fuel Savings Of More Than 20%.
The press release talks about Penzance and London, so would that be a suitable route for discontinuous electrification using multiple chargers?
These are the distances between major points on the route between Penzance and London Paddington.
- Penzance and Truro – 35.8 miles
- Truro and Bodmin Parkway – 26.8 miles
- Bodmin Parkway and Plymouth – 26.9 miles
- Plymouth and Newton Abbot – 31,9 miles
- Newton Abbot and Exeter – 20.2 miles
- Exeter and Taunton – 30.8 miles
- Taunton and Westbury – 47.2 miles
- Westbury and Newbury – 42.5 miles
- Newbury and Paddington – 53 miles
Note.
- Only Newbury and Paddington is electrified.
- Trains generally stop at Plymouth, Newton Abbott, Exeter and Taunton.
- Services between Paddington and Exeter, Okehampton, Paignton, Penzance, Plymouth and Torquay wouldn’t use diesel.
- Okehampton would be served by a reverse at Exeter.
- As Paignton is just 8.1 miles from Newton Abbot, it probably wouldn’t need a charger.
- Bodmin is another possible destination, as Great Western Railway have helped to finance a new platform at Bodmin General station.
It would certainly be good marketing to run zero-carbon electric trains to Devon and Cornwall.
I would class this route as medium risk, but with a high reward for the operator.
In this brief analysis, it does look that Hitachi’s proposed system is of a lower risk.
A Few Questions
I do have a few questions.
Are The Class 803 Trains Fitted With Hyperdrive Innovation Batteries?
East Coast Trains‘s new Class 803 trains are undergoing testing between London Kings Cross and Edinburgh and they can be picked up on Real Time Trains.
Wikipedia says this about the traction system for the trains.
While sharing a bodyshell with the previous UK A-train variants, the Class 803 differs in that it has no diesel engines fitted. They will however be fitted with batteries to enable the train’s on-board services to be maintained, in case the primary electrical supplies have failed.
Will these emergency batteries be made by Hyperdrive Innovation?
My experience of similar systems in other industries, points me to the conclusion, that all Class 80x trains can be fitted with similar, if not identical batteries.
This would give the big advantage of allowing battery testing to be performed on Class 803 trains under test, up and down the East Coast Main Line.
Nothing finds faults in the design and manufacture of something used in transport, than to run it up and down in real conditions.
Failure of the catenary can be simulated to check out emergency modes.
Can A Class 801 Train Be Converted Into A Class 803 Train?
If I’d designed the trains, this conversion would be possible.
Currently, the electric Class 801 trains have a single diesel generator. This is said in the Wikipedia entry for the Class 800 train about the Class 801 train.
These provide emergency power for limited traction and auxiliaries if the power supply from the overhead line fails.
So it looks like the difference between the powertrain of a Class 801 train and a Class 803 train, is that the Class 801 train has a diesel generator and the Class 803 train has batteries. But the diesel generator and batteries, would appear to serve the same purpose.
Surely removing diesel from a Class 801 train would ease the maintenance of the train!
Will The System Work With Third-Rail Electrification?
There are three routes that if they were electrified would probably be electrified with 750 DC third-rail electrification, as they have this electrification at one or both ends.
- Basingstoke and Exeter
- Marshlink Line
- Uckfield branch
Note.
- Basingstoke and Exeter would need a couple of charging systems.
- The Marshlink line would need a charging system at Rye station.
- The Uckfield branch would need a charging system at Uckfield station.
I am fairly certain as an Electrical Engineer, that the third-rails would only need to be switched on, when a train is connected and needs a charge.
I also feel that on some scenic and other routes, 750 VDC third-rail electrification may be more acceptable , than 25 KVAC overhead electrification. For example, would the heritage lobby accept overhead wires through a World Heritage Site or on top of a Grade I Listed viaduct?
I do feel that the ability to use third-rail 750 VDC third-rail electrification strategically could be a useful tool in the system.
Will The System Work With Lightweight Catenary?
I like the design of this 25 KVAC overhead electrification, that uses lightweight gantries, which use laminated wood for the overhead structure.
There is also a video.
Electrification doesn’t have to be ugly and out-of-character with the surroundings.
Isuspect that both systems could work together.
Would Less Bridges Need To Be Rebuilt For Electrification?
This is always a contentious issue with electrification, as rebuilding bridges causes disruption to both rail and road.
I do wonder though by the use of careful design, that it might be possible to arrange that the sections of electrification and the contentious bridges were kept apart, with the bridges arranged to be in sections, where the trains ran on batteries.
I suspect that over the years as surveyors and engineers get more experienced, better techniques will evolve to satisfy all parties.
Get this right and it could reduce the cost of electrification on some lines, that will be difficult to electrify.
How Secure Are The Containerised Systems?
Consider.
- I was delayed in East Anglia two years ago, because someone stole the overhead wires at two in the morning.
- Apparently, overhead wire stealing is getting increasingly common in France and other parts of Europe.
I suspect the containerised systems will need to be more secure than those used for buses, which are not in isolated locations.
Will The Containerised Charging Systems Use Energy Storage?
Consider.
- I’ve lived in rural locations and the power grids are not as good as in urban areas.
- Increasingly, batteries of one sort or another are being installed in rural locations to beef up local power supplies.
- A new generation of small-footprint eco-friendly energy storage systems are being developed.
In some locations, it might be prudent for a containerised charging system to share a battery with the local area.
Will The Containerised Charging Systems Accept Electricity From Local Sources Like Solar Farms?
I ask the question, as I know at least one place on the UK network, where a line without electrification runs through a succession of solar farms.
I also know of an area, where a locally-owned co-operative is planning a solar farm, which they propose would be used to power the local main line.
Will The System Work With Class 385 Trains?
Hitachi’s Class 385 trains are closely related to the Class 80x trains, as they are all members of Hitachi’s A-Train family.
Will the Charging Systems Charge Other Manufacturers Trains?
CAF and Stadler are both proposing to introduce battery-electric trains in the UK.
I also suspect that the new breed of electric parcel trains will include a battery electric variant.
As these trains will be able to use 25 KVAC overhead electrification, I would expect, that they would be able to charge their batteries on the Hitachi ABB charging systems.
Will The System Work With Freight Trains?
I believe that freight services will split into two.
Heavy freight will probably use powerful hydrogen-electric locomotives.
In Freightliner Secures Government Funding For Dual-Fuel Project, which is based on a Freightliner press release, I detail Freightliner’s decarbonisation strategy, which indicates that in the future they will use hydrogen-powered locomotives.
But not all freight is long and extremely heavy and I believe that a battery-electric freight locomotive will emerge for lighter duties.
There is no reason it could not be designed to be compatible with Hitachi’s charging system.
In Is This The Shape Of Freight To Come?, I talked about the plans for 100 mph parcel services based on redundant electric multiple units. Eversholt Rail Group have said they want a Last-Mile capability for their version of these trains.
Perhaps they need a battery-electric capability, so they can deliver parcels and shop supplies to the remoter parts of these islands?
Where Could Hitachi’s System Be Deployed?
This is the final paragraph from the article.
Hitachi is not committing to any routes yet, but a glance at the railway map shows clear potential for the battery/OLE-technology to be deployed on relatively lightly used rural and regional routes where it will be hard to make a case for electrification. The Cambrian Coast and Central Wales Lines would appear to be worthy candidates, and in Scotland, the West Highland Line and Far North routes are also logical areas for the system to be deployed.
In England, while shorter branch lines could simply be operated by battery trains, longer routes need an alternative. Network Rail’s Traction Decarbonisation Network Strategy interim business case recommends hydrogen trains for branch lines in Norfolk, as well as Par to Newquay and Exeter to Barnstaple. However, it is also entirely feasible to use the system on routes likely to be electrified much later in the programme, such as the Great Western main line West of Exeter, Swansea to Fishguard and parts of the Cumbrian Coast Line.
Everyone is entitled to their own opinion and mine would be driven by high collateral benefits and practicality.
These are my thoughts.
Long Rural Lines
The Cambrian, Central Wales (Heart Of Wales), Far North and West Highland Lines may not be connected to each other, but they form a group of rail routes with a lot of shared characteristics.
- All are rural routes of between 100 and 200 miles.
- All are mainly single track.
- They carry occasional freight trains.
- They carry quite a few tourists, who are there to sample, view or explore the countryside.
- All trains are diesel.
- Scotrail have been experimenting with attaching Class 153 trains to the trains on the West Highland Line to act as lounge cars and cycle storage.
Perhaps we need a long-distance rural train with the following characteristics.
- Four or possibly five cars
- Battery-electric power
- Space for a dozen cycles
- A lounge car
- Space for a snack trolley
- Space to provide a parcels service to remote locations.
I should also say, that I’ve used trains on routes in countries like Germany, Poland and Slovenia, where a similar train requirement exists.
Norfolk Branch Lines
Consider.
- North of the Cambridge and Ipswich, the passenger services on the branch lines and the important commuter routes between Cambridge and Norwich and Ipswich are run by Stadler Class 755 trains, which are designed to be converted to battery-electric trains.
- Using Hitachi chargers at Beccles, Bury St. Edmunds, Lowestoft, Thetford and Yarmouth and the existing electrification, battery-electric Class 755 trains could provide a zero-carbon train service for Norfolk and Suffolk.
- With chargers at Dereham and March, two important new branch lines could be added and the Ipswich and Peterborough service could go hourly and zero carbon.
- Greater Anglia have plans to use the Class 755 trains to run a London and Lowestoft service.
- Could they be planning a London and Norwich service via Cambridge?
- Would battery-electric trains running services over Norfolk bring in more visitors by train?
Hitachi may sell a few chargers to Greater Anglia, but I feel they have enough battery-electric trains.
Par And Newquay
The Par and Newquay Line or the Atlantic Coast Line, has been put forward as a Beeching Reversal project, which I wrote about in Beeching Reversal – Transforming The Newquay Line.
In that related post, I said the line needed the following.
- An improved track layout.
- An hourly service.
- An improved Par station.
- A rebuilt Newquay station with a second platform, so that more through trains can be run.
I do wonder, if after the line were to be improved, that a new three-car battery-electric train shuttling between Par and Newquay stations could be the icing on the cake.
Exeter And Barnstaple
The Tarka Line between Exeter and Barnstaple is one of several local and main lines radiating from Exeter St. David’s station.
- The Avocet Line to Exmouth
- The Great Western Main Line to Taunton, Bristol and London
- The Great Western Main Line to Newton Abbott, Plymouth and Penzance
- The Riviera Line to Paignton
- The West of England Line to Salisbury, Basingstoke and London.
Note.
- The Dartmoor Line to Okehampton is under development.
- Several new stations are planned on the routes.
- I have already stated that Exeter could host a charging station between London and Penzance, but it could also be an electrified hub for battery-electric trains running hither and thither.
Exeter could be a city with a battery-electric metro.
Exeter And Penzance
Earlier, I said that I’d trial multiple chargers between Paddington and Penzance to prove the concept worked.
I said this.
I would class this route as medium risk, but with a high reward for the operator.
But it is also an enabling route, as it would enable the following battery-electric services.
- London and Bodmin
- London and Okehampton
- London and Paignton and Torquay
It would also enable the Exeter battery-electric metro.
For these reasons, this route should be electrified using Hitachi’s discontinuous electrification.
Swansea And Fishguard
I mentioned Swansea earlier, as a station, that could be fitted with a charging system, as this would allow battery-electric trains between Paddington and Swansea via Cardiff.
Just as with Exeter, there must be scope at Swansea to add a small number of charging systems to develop a battery-electric metro based on Swansea.
Cumbrian Coast Line
This is a line that needs improvement, mainly for the tourists and employment it could and probably will bring.
These are a few distances.
- West Coast Main Line (Carnforth) and Barrow-in-Furness – 28.1 miles
- Barrow-in-Furness and Sellafield – 25 miles
- Sellafield and Workington – 18 miles
- Workington and West Coast Main Line (Carlisle) – 33 miles
Note.
- The West Coast Main Line is fully-electrified.
- I suspect that Barrow-in-Furness, Sellafield and Workington have good enough electricity supplies to support charging systems for the Cumbrian Coast Line.
- The more scenic parts of the line would be left without wires.
It certainly is a line, where a good case for running battery-electric trains can be made.
Crewe And Holyhead
In High-Speed Low-Carbon Transport Between Great Britain And Ireland, I looked at zero-carbon travel between the Great Britain and Ireland.
One of the fastest routes would be a Class 805 train between Euston and Holyhead and then a fast catamaran to either Dublin or a suitable rail-connected port in the North.
- The Class 805 trains could be made battery-electric.
- The trains could run between Euston and Crewe at speeds of up to 140 mph under digital signalling.
- Charging systems would probably be needed at Chester, Llandudno Junction and Holyhead.
- The North Wales Coast Line looks to my untrained eyes, that it could support at least some 100 mph running.
I believe that a time of under three hours could be regularly achieved between London Euston and Holyhead.
Battery-electric trains on this route, would deliver the following benefits.
- A fast low-carbon route from Birmingham, London and Manchester to the island of Ireland. if coupled with the latest fast catamarans at Holyhead.
- Substantial reductions in journey times to and from Anglesey and the North-West corner of Wales.
- Chester could become a hub for battery-electric trains to and from Birmingham, Crewe, Liverpool, Manchester and Shrewsbury.
- Battery-electric trains could be used on the Conwy Valley Line.
- It might even be possible to connect the various railways, heritage railways and tourist attractions in the area with zero-carbon shuttle buses.
- Opening up of the disused railway across Anglesey.
The economics of this corner of Wales could be transformed.
My Priority Routes
To finish this section, I will list my preferred routes for this method of discontinuous electrification.
- Exeter and Penzance
- Swansea and Fishguard
- Crewe and Holyhead
Note.
- Some of the trains needed for these routes have been delivered or are on order.
- Local battery-electric services could be developed at Chester, Exeter and Swansea by building on the initial systems.
- The collateral benefits could be high for Anglesey, West Wales and Devon and Cornwall.
I suspect too, that very little construction work not concerned with the installation of the charging systems will be needed.
Conclusion
Hitachi have come up with a feasible way to electrify Great Britain’s railways.
I would love to see detailed costings for the following.
- Adding a battery pack to a Class 800 train.
- Installing five miles of electrification supported by a containerised charging system.
They could be on the right side for the Treasury.
But whatever the costs, it does appear that the Japanese have gone native, with their version of the Great British Compromise.
Ten Innovative Approaches To Tackling Climate Change From Our Carbon Revolution Series
The title of this post, is the same as that of this article on Dezeen.
It is a very definite must read!
Air Passengers Can Beat Queues With Uber-Style Private Jet Service
The title of this post, is the same as that of this article on The Times.
Hyer Aviation are starting a service that uses similar technology to Uber to share seats on private jets around Europe.
Their modus operandi is laid out in this press release on their web site.
This paragraph is from the press release.
The concept works like an extra-comfortable UberPool with wings. Passengers can initiate their own flight or join flights proposed by others. This allows them to fly on private aircraft for a fraction of the cost while offsetting the carbon emission of their flights. From London, routes are available to some of Britain’s favourite holiday destinations such as Ibiza, Cannes, Malaga, Amalfi Coast and Amsterdam. From Amsterdam, it is also possible to find flights proposed by other passengers to Nice and Ibiza.
think this business model could fly.
Years ago, I owned a twin piston-engined six seater aircraft and I flew it all over Europe. I don’t fly now, as my medical history would probably stop that, but the experience showed there are many quiet airports all over the UK and Europe, that could be destinations for a 6-9 seater aircraft.
To me the interesting thing about this business model, is that there are several zero-carbon 6-9 seater aircraft under development.
Two are electric developments of the widely-used Cessna Caravan and the Britten-Norman Islander and others are clean-sheet developments like the Eviation Alice or the Faradair BEHA.
ZeroAvia are also experimenting with a hydrogen-powered Piper Malibu.
An electric or zero-carbon future for aviation is closer than many think.
But it will start at the smaller end with ranges of up to 500 miles.
My First Ride In A Class 769 Train
I went to Cardiff today and had my first ride in a Class 769 train. These pictures summarise my ride on the train between Cardiff Central and Bargoed stations.
So what was it like?
Noise And Vibration
Going up to Bargoed, I deliberately sat as near over the top of the engine as I could.
There was a bit of a whine, but not as much as in a new Class 195 train.
For those, who commuted on Class 319 trains for years on Thameslink, they probably wouldn’t notice much difference.
Performance
For a 100 mph electric train built for running between the flat lands of Bedfordshire and the South Coast over the hillocks of the Downs, the train climbed to Bengoed, which has an altitude of around a thousand feet with a purpose.
But then I have a Porterbrook brochure for these trains and the power source was sized, such that the train would be able to climb the stiffest routes in the UK.
The Interior
It looked to me like the Thameslink interior with new sea covers and plugs to charge a mobile phone.
They could certainly be upgraded a bit further to the standard of the Class 319 trains on the Abbey Line, that I wrote about in A Very Smart Class 319 Train.
A Job To Do
Trains for Wales has acquired these trains for extra capacity, whilst they refurbish their Class 150, 153 and 160 trains.
It looks to me, that they will do this job more than adequately.
Future Uses
I suspect Porterbrook hope that these trains will find uses around the UK, as they have spent a lot of time, effort and money to bring these trains into service.
But there are around eighty of the Class 319 trains in service or in store, from which the Class 769 trains are converted.
So they could find uses in several niche applications.
Short Term Fleets
This is effectively, the Trains for Wales application, where extra trains are provided, so that a fleet refurbishment can be performed.
- They would surely, have been a better replacement fleet for Greater Anglia, than the three Mark 2 coaches and a pair of diesel locomotives, that they used after a series of level crossing accidents.
- They could also be used to increase capacity for some major events like the Open Golf or a pop festival.
- Uniquely, they can stand in for both a 100 mph electric train or a 90 mph diesel train.
- They can even be fitted with third-rail shoes.
- They are the right size at four cars.
- They fit most UK platforms.
- They can be run in formations of up to twelve cars.
I wouldn’t be surprised to see Porterbrook or someone on their behalf, keep a fleet of trains on standby to handle short term needs.
Route Development And Testing
There has been a lot of pressure to open up new routes in recent years and these trains would be ideal to try out routes and test new electrification.
Tri-Mode Services
Great Western Railway have a particular problem with their service between Reading and Gatwick, in that it has some third-rail electrification. As they might like to extend this service to Oxford, an ideal train would be dual-voltage and self-powered.
This extract is from the Great Western Railway section in the Wikipedia entry for the Class 769 train.
Although initially planned for use in London and the Thames Valley whilst twelve Class 387 units are modified for Heathrow Express services, the future plan for these units will be operating on services between Oxford, Reading and Gatwick Airport, which would mean operating on unelectrified, 25 kV AC OHLE and 750 V DC third-rail routes. To enable this, Great Western Railway’s allocation of Class 769 units will retain their dual-voltage capability in addition to being fitted with diesel power units. The units will also receive an internal refurbishment and be fitted with air cooling.
I suspect, that they’ll also be used on the Henley, Marlow and Windsor branches, which have some operational problems.
- The branches are not electrified.
- Some branches run occasional services to Paddington.
- The Windsor branch probably needs more capacity.
The Marlow branch could be difficult, but I suspect that, there’s a solution somewhere.
Luxury Bi-Modes
Greater Anglia felt they needed luxury bi-modes for East Anglia and they bought Class 755 trains, which are probably a lot more expensive, as they are brand-new and from Stadler of Switzerland.
Surprisingly, the Class 319 trains have a higher passenger capacity.
But both trains could do a similar task, where the route is partially electrified.
As I said earlier about the GWR units.
The units will also receive an internal refurbishment and be fitted with air cooling.
Porterbrook’s brochure for the Class 769 train talks about using them between Manchester and Buxton.
Surely, this route could do with a Northern version of a GWR interior.
I also think a service should link Hellifield and Buxton. as I wrote about in Why Not Buxton To Hellifield?
That would show what Class 769 trains could do!
It would also connect the Peak District to the hills North of Lancashire.
I might also be, that the standby-fleet should also be the luxury variant of the train. Surely, supporters going to the Open at some of the inaccessible venues could afford pay to pay extra for a comfy train.
Express Freight And Parcels Services
Rail Operations Group would appear to have placed the second-largest order for Class 769 trains, which they will use to launch a high-speed parcels service called Orion.
This extract is from the Rail Operations Group section in the Wikipedia entry for the Class 769 train.
Orion is aiming to launch its first trial service conveying parcels and light freight in April 2021, with the Midlands to Mossend now likely to be the debut flow. The company is to use converted Class 319s for the service and is now planning for a fleet of 19 four-car units – nine Class 319s and 10 Class 769s. Arlington Fleet Services at Eastleigh is modifying the interiors of the units to accommodate roller cages for parcels, with the aim of operating primarily under electric power but with the 769s using their diesel engines to act as tractor units for the 319s on non-electrified stretches. The first 769 bi-mode, No 769501, has undergone its Flex conversion at Brush in Loughborough and is due to be outshopped from Arlington at Eastleigh in March following its interior modification.
In Did These Strawberries Have Road- Or Rail-Miles?, I talked about strawberries going between Scotland and London.
Surely, the movement of high-quality food could be one of the cargoes for Orion.
It wouldn’t be the first such traffic, as Class 43 power cars of the InterCity 125s used to carry flowers and fish up to London from Cornwall.
There’s a lot of space in the back of a Class 43 power car.
I certainly feel there are possibilities for using Class 769 trains as high speed parcels transport.
It should be noted that Class 325 trains already run high speed parcel services up and down the country on behalf of Royal Mail. These trains may look like later British Rail trains, but they are in fact based on Class 319 trains.
So I doubt, there’ll be any worries that the trains can’t handle the required services after conversion.
Conclusion
It looks to me that Porterbrooks plan to convert numbers of their Class 319 trains into Class 769 trains will find several ready markets.
It could be argued that more carbon savings could be achieved by perhaps a new battery-electric or hydrogen-electric train. But these will take years to develop!
These trains are a good short-term solution, that will help define their zero-carbon successors.
Heidelberg Plans Net-Zero Cement Plant For Sweden
The title of this post, is the same as that of this article on The Times.
Making cement creates about ten percent of man-made carbon emissions. See Wikipedia for CO2 Emissions From Cement.
Making cement needs a lot of energy and I suspect most comes from natural gas these days.
But I suspect there are ways to simply cut the carbon emissions.
- Making cement is a continuous process and I suspect adding carbon capture would be easier than with other industrial processes like steelmaking.
- Hydrogen rather than natural gas could be used to provide energy.
There also may be other ways of making cement. See Ecological Cement on Wikipedia.
DfT To Have Final Say On Huddersfield Rebuild Of Rail Station And Bridges
The title of this post, is the same as that of this article on Rail Technology Magazine.
This is the first paragraph.
As part of the £1.4bn Transpennine Route Upgrade. Transport Secretary Grant Shapps is to rule on planned changes to Huddersfield’s 19th century rail station and not the Kirklees council, in what is to be a huge revamp of the line between Manchester and York.
According to the article eight bridges are to be replaced or seriously modified.
As Huddersfield station (shown) is Grade I listed and three other Grade II listed buildings and structures are involved, I can see this project ending up with a substantial bill for lawyers.
But then, to have a world-class railway across the Pennines, a few eggs will need to be broken.
Electric Trains Across The Pennine
This page on the Network Rail web site describes the Huddersfield To Westtown (Dewsbury) Upgrade.
When the upgrade and the related York To Church Fenton Improvement Scheme is completed, the TransPennine route between Huddersfield and York will be fully-electrified.
As Manchester To Stalybridge will also have been electrified, this will mean that the only section without electrification will be the eighteen miles across the Pennines between Stalybridge and Huddersfield.
Will this final eighteen miles ne electrified?
Eighteen miles with electrification at both ends will be a short jump for a Hitachi Intercity Tri-Mode Battery Train, the specification of which is shown in this Hitachi infographic.
The Class 802 trains of TransPennine Express are able to be converted into these trains.
The trains could work these routes.
- Liverpool Lime Street and Scarborough
- Manchester Airport and Redcar
- Liverpool Lime Street and Edinburgh via Newcastle
- Manchester Airport and Newcastle
- Manchester Piccadilly and Hull
- Manchester Airport and Cleethorpes
Note.
- I suspect some more Class 802 trains with batteries will be needed.
- The trains would either use battery or diesel power to reach Hull, Redcar and Scarborough or there could be a few miles of electrification to stretch battery range.
- Will the Class 68 diesel locomotives be replaced with Class 93 tri-mode locomotives to haul the Mark 5A coaches to Scarborough.
- Manchester Airport and Cleethorpes could be a problem and will probably need some electrification around Sheffield and Grimsby.
This would just mean TransPennine’s two short routes to be decarbonised.
- Manchester Piccadilly and Huddersfield
- Huddersfield and Leeds
As except for the eighteen mile gap between Stalybridge and Huddersfield, these two routes are fully-electrified, I suspect that a battery-electric version of a 110 mph electric train like a Class 387 or Class 350 train could run these routes.
Conclusion
It looks like if these sections of the TransPennine Express network are upgraded and electrified.
- York and Church Fenton
- Huddersfield and Westtown
- Manchester and Staylebridge
Together with a few extra miles of electrification at strategic points, that TransPennine Express will be able to decarbonise.
BECCS Beats Hydrogen For Decarbonizing Steel In Europe: ArcelorMittal
The title of this post, is the same as that of this article on S & P Global Platts.
This is the first paragraph.
Bioenergy with carbon capture and storage (BECCS) offers a more cost-effective, readily available solution for decarbonizing the steel industry in Europe than clean hydrogen, steel producer ArcelorMittal’s head of strategy David Clarke said May 17.
So what do they mean by bioenergy?
To make iron from iron ore, you need a reducing agent like carbon or hydrogen.
Iron ore is rich in oxides of iron.
The carbon is usually some form of coal, which produces large amounts of carbon dioxide with the oxygen from the iron oxides.
Hydrogen produces lots of water with the oxygen.
David Clarke of ArcelorMittal explains the process in the article.
“We know biomass worked as a replacement for coal,” he said. “We’ve been using it in our operations in Brazil and other places for many, many years. We have a project in Belgium that we’ll be starting up next year using waste wood, using that to make bio-coal,” with a project to take the emissions from the bio-coal to produce bioethanol.
Is this a case of Back-To-The-Future? If I remember my history, didn’t Iron Age men use charcoal to smelt iron and other metal ores?
If those scientists from Velocys can make Sustainable Aviation Fuel and biodiesel from household waste and used disposable nappies, can they apply their magic to make bio-coal?
I see great cost advantages with this process, as surely it would enable existing blast furnaces to be used, provided they were fitted with carbon capture and storage.
Gigawatt-Scale Compressed Air: World’s Largest Non-Hydro Energy-Storage Projects Announced
The title of this post, is the same as that of this article on Recharge.
This is the opening paragraph.
The two 500MW/5GWh ‘advanced’ compressed-air projects in California would each be bigger than the current record holder.
They are certainly not small. On the Electric Mountain scale of energy storage, they are both 55 %.
Both appear to be from Canadian company; Hydrostor and will be built in California.
This explanatory video is from the company.
It appears to be a rather elegant solution.
Like Highview Power, the system appears to be based on proven process technology, is zero-carbon, can be built almost anywhere and doesn’t require large amounts of land.
Hydrostor is definitely one to watch.
My only worry about both Hydrostor and Highview systems, is that countries, who don’t recognise patents and design copyrights could develop other systems based on similar physical principles.
High-Speed Low-Carbon Transport Between Great Britain And Ireland
Consider.
- According to Statista, there were 13,160,000 passengers between the United Kingdom and the Irish Republic in 2019.
- In 2019, Dublin Airport handled 32,907,673 passengers.
- The six busiest routes from Dublin were Heathrow, Stansted, Amsterdam, Manchester, Birmingham and Stansted.
- In 2018, Belfast International Airport handled 6,269,025 passengers.
- The four busiest routes from Belfast International Airport were Stansted, Gatwick. Liverpool and Manchester, with the busiest route to Europe to Alicante.
- In 2018, Belfast City Airport handled 2,445,529 passengers.
- The four busiest routes from Belfast City Airport were Heathrow, Manchester, Birmingham and London City.
Note.
- The busiest routes at each airport are shown in descending order.
- There is a lot of air passengers between the two islands.
- Much of the traffic is geared towards London’s four main airports.
- Manchester and Liverpool get their fair share.
Decarbonisation of the air routes between the two islands will not be a trivial operation.
But technology is on the side of decarbonisation.
Class 805 Trains
Avanti West Coast have ordered thirteen bi-mode Class 805 trains, which will replace the diesel Class 221 trains currently working between London Euston and Holyhead.
- They will run at 125 mph between Euston and Crewe using electric power.
- If full in-cab digital signalling were to be installed on the electrified portion of the route, they may be able to run at 140 mph in places under the wires.
- They will use diesel power on the North Wales Coast Line to reach Holyhead.
- According to an article in Modern Railways, the Class 805 trains could be fitted with batteries.
I wouldn’t be surprised that when they are delivered, they are a version of the Hitachi’s Intercity Tri-Mode Battery Train, the specification of which is shown in this Hitachi infographic.
Note.
- I suspect that the batteries will be used to handle regenerative braking on lines without electrification, which will save diesel fuel and carbon emissions.
- The trains accelerate faster, than those they replace.
- The claimed fuel and carbon saving is twenty percent.
It is intended that these trains will be introduced next year.
I believe that, these trains will speed up services between London Euston and Holyhead.
- Currently, services take just over three-and-a-half hours.
- There should be time savings on the electrification between London Euston and Crewe.
- The operating speed on the North Wales Coast Line is 90 mph. This might be increased in sections.
- Some extra electrification could be added, between say Crewe and Chester and possibly through Llandudno Junction.
- I estimate that on the full journey, the trains could reduce emissions by up to sixty percent compared to the current diesel trains.
I think that a time of three hours could be achievable with the Class 805 trains.
New trains and a three hour journey time should attract more passengers to the route.
Holyhead
In Holyhead Hydrogen Hub Planned For Wales, I wrote about how the Port of Holyhead was becoming a hydrogen hub, in common with several other ports around the UK including Felixstowe, Harwich, Liverpool and Portsmouth.
Holyhead and the others could host zero-carbon hydrogen-powered ferries.
But this extract from the Wikipedia hints at work needed to be done to create a fast interchange between trains and ferries.
There is access to the port via a building shared with Holyhead railway station, which is served by the North Wales Coast Line to Chester and London Euston. The walk between trains and ferry check in is less than two minutes, but longer from the remote platform 1, used by Avanti West Coast services.
This Google Map shows the Port of Holyhead.
I think there is a lot of potential to create an excellent interchange.
HSC Francisco
I am using the high-speed craft Francisco as an example of the way these ships are progressing.
- Power comes from two gas-turbine engines, that run on liquified natural gas.
- It can carry 1024 passengers and 150 cars.
- It has a top speed of 58 knots or 67 mph. Not bad for a ship with a tonnage of over 7000.
This ship is in service between Buenos Aires and Montevideo.
Note.
- A craft like this could be designed to run on zero-carbon liquid hydrogen or liquid ammonia.
- A high speed craft already runs between Dublin and Holyhead taking one hour and forty-nine minutes for the sixty-seven miles.
Other routes for a specially designed high speed craft might be.
- Barrow and Belfast – 113 miles
- Heysham and Belfast – 127 miles
- Holyhead and Belfast – 103 miles
- Liverpool and Belfast – 145 miles
- Stranraer and Larne – 31 miles
Belfast looks a bit far from England, but Holyhead and Belfast could be a possibility.
London And Dublin Via Holyhead
I believe this route is definitely a possibility.
- In a few years, with a few improvements on the route, I suspect that London Euston and Holyhead could be fairly close to three hours.
- With faster bi-mode trains, Manchester Airport and Holyhead would be under three hours.
- I would estimate, that a high speed craft built for the route could be under two hours between Holyhead and Dublin.
It certainly looks like London Euston and Dublin and Manchester Airport and Dublin would be under five hours.
In A Glimpse Of 2035, I imagined what it would be like to be on the first train between London and Dublin via the proposed fixed link between Scotland and Northern Ireland.
- I felt that five-and-a-half hours was achievable for that journey.
- The journey would have used High Speed Two to Wigan North Western.
- I also stated that with improvements, London and Belfast could be three hours and Dublin would be an hour more.
So five hours between London Euston and Dublin using current technology without massive improvements and new lines could be small change well spent.
London And Belfast Via Holyhead
At 103 miles the ferry leg may be too long for even the fastest of the high speed craft, but if say the craft could do Holyhead and Belfast in two-and-a-half hours, it might just be a viable route.
- It might also be possible to run the ferries to a harbour like Warrenpoint, which would be eighty-six miles.
- An estimate based on the current high speed craft to Dublin, indicates a time of around two hours and twenty minutes.
It could be viable, if there was a fast connection between Warrenpoint and Belfast.
Conclusion
Once the new trains are running between London Euston and Holyhead, I would expect that an Irish entrepreneur will be looking to develop a fast train and ferry service between England and Wales, and the island of Ireland.
It could be sold, as the Greenest Way To Ireland.
Class 807 Trains
Avanti West Coast have ordered ten electric Class 807 trains, which will replace some of the diesel Class 221 trains.
- They will run at 125 mph between Euston and Liverpool on the fully-electrified route.
- If full in-cab digital signalling were to be installed on the route, they may be able to run at 140 mph in places.
- These trains appear to be the first of the second generation of Hitachi trains and they seem to be built for speed and a sparking performance,
- These trains will run at a frequency of two trains per hour (tph) between London and Liverpool Lime Street.
- Alternate trains will stop at Liverpool South Parkway station.
In Will Avanti West Coast’s New Trains Be Able To Achieve London Euston and Liverpool Lime Street In Two Hours?, I came to the conclusion, that a two-hour journey time was possible, when the new Class 807 trains have entered service.
London And Belfast Via Liverpool And A Ferry
Consider.
- An hour on the train to and from London will be saved compared to Holyhead.
- The ferry terminal is in Birkenhead on the other side of the Mersey and change between Lime Street station and the ferry could take much longer than at Holyhead.
- Birkenhead and Belfast is twice the distance of Holyhead and Dublin, so even a high speed craft would take three hours.
This Google Map shows the Ferry Terminal and the Birkenhead waterfront.
Note.
- The Ferry Terminal is indicated by the red arrow at the top of the map.
- There are rows of trucks waiting for the ferries.
- In the South East corner of the map, the terminal of the Mersey Ferry sticks out into the River
- Hamilton Square station is in-line with the Mersey Ferry at the bottom of the map and indicated with the usual red symbol.
- There is a courtesy bus from Hamilton Square station to the Ferry Terminal for Ireland.
There is a fourteen tph service between Hamilton Square and Liverpool Lime Street station.
This route may be possible, but the interchange could be slow and the ferry leg is challenging.
I don’t think the route would be viable unless a much faster ferry is developed. Does the military have some high speed craft under development?
Conclusion
London and Belfast via Liverpool and a ferry is probably a trip for enthusiasts or those needing to spend a day in Liverpool en route.
Other Ferry Routes
There are other ferry routes.
Heysham And Barrow-in-Furness
,These two ports might be possible, but neither has a good rail connection to London and the South of England.
They are both rail connected, but not to the standard of the connections at Holyhead and Liverpool.
Cairnryan
The Cairnryan route could probably be improved to be an excellent low-carbon route to Glasgow and Central Scotland.
Low-Carbon Flight Between The Islands Of Great Britain And Ireland
I think we’ll gradually see a progression to zero-carbon flight over the next few years.
Sustainable Aviation Fuel
Obviously zero-carbon would be better, but until zero-carbon aircraft are developed, there is always sustainable aviation fuel.
This can be produced from various carbon sources like biowaste or even household rubbish and disposable nappies.
British Airways are involved in a project called Altalto.
- Altalto are building a plant at Immingham to turn household rubbish into sustainable aviation fuel.
- This fuel can be used in jet airliners with very little modification of the aircraft.
I wrote about Altalto in Grant Shapps Announcement On Friday.
Smaller Low-Carbon Airliners
The first low- and zero-carbon airliners to be developed will be smaller with less range, than Boeing 737s and Airbus A 320s. These three are examples of four under development.
- Aura Aero Era – 19 passengers – 500 miles
- Eviation Alice – 9 passengers – 620 miles
- Faradair Aerospace BEHA – 19 passengers – 1150 miles
- Heart Aerospace ES-19 – 19 passengers – 400 km.
I feel that a nineteen seater aircraft with a range of 500 miles will be the first specially designed low- or zero-carbon airliner to be developed.
I believe these aircraft will offer advantages.
- Some routes will only need refuelling at one end.
- Lower noise and pollution.
- Some will have the ability to work from short runways.
- Some will be hybrid electric running on sustainable aviation fuel.
They may enable passenger services to some smaller airports.
Air Routes Between The Islands Of Great Britain And Ireland
These are distances from Belfast City Airport.
- Aberdeen – 228 miles
- Amsterdam – 557 miles
- Birmingham – 226 miles
- Blackpool – 128 miles
- Cardiff – 246 miles
- Edinburgh – 135 miles
- Gatwick – 337 miles
- Glasgow – 103 miles
- Heathrow – 312 miles
- Jersey – 406 miles
- Kirkwall – 320 miles
- Leeds – 177 miles
- Liverpool – 151 miles
- London City – 326 miles
- Manchester – 170 miles
- Newcastle – 168 miles
- Southampton – 315 miles
- Southend – 344 miles
- Stansted – 292 miles
- Sumburgh – 401 miles
Note.
- Some airports on this list do not currently have flights from Belfast City Airport.
- I have included Amsterdam for comparison.
- Distances to Belfast International Airport, which is a few miles to the West of Belfast City Airport are within a few miles of these distances.
It would appear that much of Great Britain is within 500 miles of Belfast City Airport.
These are distances from Dublin Airport.
- Aberdeen – 305 miles
- Amsterdam – 465 miles
- Birmingham – 199 miles
- Blackpool – 133 miles
- Cardiff – 185 miles
- Edinburgh – 208 miles
- Gatwick – 300 miles
- Heathrow – 278 miles
- Jersey – 339 miles
- Kirkwall – 402 miles
- Leeds – 190 miles
- Liverpool – 140 miles
- London City – 296 miles
- Manchester – 163 miles
- Newcastle – 214 miles
- Southampton – 268 miles
- Southend – 319 miles
- Stansted – 315 miles
- Sumburgh – 483 miles
Note.
- Some airports on this list do not currently have flights from Dublin Airport.
- I have included Amsterdam for comparison.
It would appear that much of Great Britain is within 500 miles of Dublin Airport.
I will add a few long routes, that someone might want to fly.
- Cork and Aberdeen – 447 miles
- Derry and Manston – 435 miles
- Manston and Glasgow – 392 miles
- Newquay and Aberdeen – 480 miles
- Norwich and Stornaway – 486 miles.
I doubt there are many possible air services in the UK and Ireland that are longer than 500 miles.
I have a few general thoughts about low- and zero-carbon air services in and around the islands of Great Britain and Ireland.
- The likely five hundred mile range of the first generation of low- and zero-carbon airliners fits the size of the these islands well.
- These aircraft seem to have a cruising speed of between 200 and 250 mph, so flight times will not be unduly long.
- Airports would need to have extra facilities to refuel or recharge these airliners.
- Because of their size, there will need to be more flights on busy routes.
- Routes which are less heavily used may well be developed, as low- or zero-carbon could be good for marketing the route.
I suspect they could be ideal for the development of new routes and even new eco-friendly airports.
Conclusion
I have come to the conclusion, that smaller low- or zero-carbon are a good fit for the islands of Great Britain and Ireland.
But then Flybe and Loganair have shown that you can make money flying smaller planes around these islands with the right planes, airports, strategy and management.
Hydrogen-Powered Planes From Airbus
Hydrogen-powered zero-carbon aircraft could be the future and Airbus have put down a marker as to the way they are thinking.
Airbus have proposed three different ZEROe designs, which are shown in this infographic.
The turboprop and the turbofan will be the type of designs, that could be used around Great Britain and Ireland.
The ZEROe Turboprop
This is Airbus’s summary of the design for the ZEROe Turboprop.
Two hybrid hydrogen turboprop engines, which drive the six bladed propellers, provide thrust. The liquid hydrogen storage and distribution system is located behind the rear pressure bulkhead.
This screen capture taken from the video, shows the plane.
It certainly is a layout that has been used successfully, by many conventionally-powered aircraft in the past. The De Havilland Canada Dash 8 and ATR 72 are still in production.
I don’t think the turboprop engines, that run on hydrogen will be a problem.
If you look at the Lockheed-Martin C 130J Super Hercules, you will see it is powered by four Rolls-Royce AE 2100D3 turboprop engines, that drive 6-bladed Dowty R391 composite constant-speed fully-feathering reversible-pitch propellers.
These Rolls-Royce engines are a development of an Allison design, but they also form the heart of Rolls-Royce’s 2.5 MW Generator, that I wrote about in Our Sustainability Journey. The generator was developed for use in Airbus’s electric flight research program.
I wouldn’t be surprised to find the following.
- , The propulsion system for this aircraft is under test with hydrogen at Derby and Toulouse.
- Dowty are testing propellers suitable for the aircraft.
- Serious research is ongoing to store enough liquid hydrogen in a small tank that fits the design.
Why develop something new, when Rolls-Royce, Dowty and Lockheed have done all the basic design and testing?
This screen capture taken from the video, shows the front view of the plane.
From clues in the picture, I estimate that the fuselage diameter is around four metres. Which is not surprising, as the Airbus A320 has a height of 4.14 metres and a with of 3.95 metres. But it’s certainly larger than the fuselage of an ATR-72.
So is the ZEROe Turboprop based on a shortened Airbus A 320 fuselage?
- The ATR 72 has a capacity of 70 passengers.
- The ZEROe Turboprop has a capacity of less than a hundred passengers.
- An Airbus A320 has six-abreast seating.
- Could the ZEROe Turboprop have sixteen rows of seats, as there are sixteen windows in front of the wing?
- With the seat pitch of an Airbus A 320, which is 81 centimetres, this means just under thirteen metres for the passengers.
- There could be space for a sizeable hydrogen tank in the rear part of the fuselage.
- The plane might even be able to use the latest A 320 cockpit.
It looks to me, that Airbus have designed a larger ATR 72 based on an A 320 fuselage.
I don’t feel there are any great technical challenges in building this aircraft.
- The engines appear to be conventional and could even have been more-or-less fully developed.
- The fuselage could be a development of an existing design.
- The wings and tail-plane are not large and given the company’s experience with large composite structures, they shouldn’t be too challenging.
- The hydrogen storage and distributing system will have to be designed, but as hydrogen is being used in increasing numbers of applications, I doubt the expertise will be difficult to find.
- The avionics and other important systems could probably be borrowed from other Airbus products.
Given that the much larger and more complicated Airbus A380 was launched in 2000 and first flew in 2005, I think that a prototype of this aircraft could fly around the middle of this decade.
It may seem small at less than a hundred seats, but it does have a range of greater than a 1000 nautical miles or 1150 miles.
Consider.
- It compares closely in passenger capacity, speed and range, with the De Havilland Canada Dash 8/400 and the ATR 72/600.
- The ATR 72 is part-produced by Airbus.
- The aircraft is forty percent slower than an Airbus A 320.
- It looks like it could be designed to have a Short-Takeoff-And Landing (STOL) capability.
I can see the aircraft replacing Dash 8s, ATR 72s and similar aircraft all over the world. There are between 2000 and 3000 operational airliners in this segment.
The ZEROe Turbofan
This is Airbus’s summary of the design.
Two hybrid hydrogen turbofan engines provide thrust. The liquid hydrogen storage and distribution system is located behind the rear pressure bulkhead.
This screen capture taken from the video, shows the plane.
This screen capture taken from the video, shows the front view of the plane.
The aircraft doesn’t look very different different to an Airbus A320 and appears to be fairly conventional. It does appear to have the characteristic tall winglets of the A 320 neo.
I don’t think the turbofan engines, that run on hydrogen will be a problem.
These could be standard turbofan engines modified to run on hydrogen, fuelled from a liquid hydrogen tank behind the rear pressure bulkhead of the fuselage.
If you want to learn more about gas turbine engines and hydrogen, read this article on the General Electric web site, which is entitled The Hydrogen Generation: These Gas Turbines Can Run On The Most Abundant Element In the Universe,
These are my thoughts of the marketing objectives of the ZEROe Turbofan.
- The cruising speed and the number of passengers are surprisingly close, so has this aircraft been designed as an A 320 or Boeing 737 replacement?
- I suspect too, that it has been designed to be used at any airport, that could handle an Airbus A 320 or Boeing 737.
- It would be able to fly point-to-point flights between most pairs of European or North American cities.
It would certainly fit the zero-carbon shorter range airliner market!
In fact it would more than fit the market, it would define it!
I very much believe that Airbus’s proposed zero-carbon hydrogen-powered designs and others like them will start to define aviation on routes of up to perhaps 3000 miles, from perhaps 2035.
- The A 320 neo was launched in December 2010 and entered service in January 2016. That was just five years and a month.
- I suspect that a lot of components like the fuselage sections, cockpit, avionics, wings, landing gear, tailplane and cabin interior could be the same in a A 320 neo and a ZEROe Turbofan.
- Flying surfaces and aerodynamics could be very similar in an A 320 neo and a ZEROe Turbofan
- There could even be commonality between the ZEROe Turboprop and the ZEROe Turbofan, with respect to fuselage sections, cockpit, avionics and cabin interior.
There also must be the possibility, that if a ZEROe Turbofan is a hydrogen-powered A 320 neo, that this would enable the certification process to be simplified.
It might even be possible to remanufacture a A 320 neo into a ZEROe Turbofan. This would surely open up all sorts of marketing strategies.
My project management, flying and engineering knowledge says that if they launched the ZEROe Turbofan this year, it could be in service by the end of the decade on selected routes.
Conclusion
Both the ZEROe Turboprop and ZEROe Turbofan are genuine zero-carbon aircraft, which fit into two well-defined market segments.
I believe that these two aircraft and others like them from perhaps Boeing and Bombardier could be the future of aviation between say 500 and 3000 miles.
With the exception of the provision of hydrogen refuelling at airports, there will be no need for any airport infrastructure.
I also wouldn’t be surprised that the thinking Airbus appear to have applied to creating the ZEROe Turbofan from the successful A 320 neo, could be applied to perhaps create a hydrogen-powered A 350.
I feel that Airbus haven’t fulling disclosed their thinking. But then no company would, when it reinvents itself.
T also think that short-haul air routes will increasing come under pressure.
The green lobby would like airlines to decarbonise.
Governments will legislate that airlines must decarbonise.
The rail industry will increasingly look to attract customers away from the airlines, by providing more competitive times and emphasising their green credentials.
Aircraft manufacturers will come under pressure to deliver zero-carbon airliners as soon as they can.
I wouldn’t be surprised to see a prototype ZEROe Turbofan or Boeing’s equivalent fly as early as 2024.
Short Term Solutions
As I said earlier, one solution is to use existing aircraft with Sustainable Aviation Fuel.
But many believe this is greenwash and rather a cop out.
So we must do better!
I don’t believe that the smaller zero- and low-carbon aircraft with a range of up to 500 miles and a capacity of around 19 seats, will be able to handle all the passengers needing to fly between and around the islands of Great Britain and Ireland.
- A Boeing 737 or Airbus A 320 has a capacity of around two hundred passengers, which would require ten times the number of flights, aircraft and pilots.
- Airports would need expansion on the airside and the terminals to handle the extra planes.
- Air Traffic Control would need to be expanded to handle the extra planes.
But the smaller planes would be ideal for the thinner secondary routes.
So I tend to think, that the greens will have to lump it, as Sustainable Aviation Fuel will increasingly be the only viable solution.
This will increase the need for Airbus or Boeing to develop a viable A 320 or 737-sized aircraft as soon as possible.
Air Bridges
I said earlier, that I believe using ferries between Ireland and Holyhead and new bi-mode Class 805 trains between London Euston and Holyhead could be a competitor to airlines.
- The ferries would be high speed craft capable of Holyhead and Ireland in around 90-100 minutes.
- The ferries would be zero-carbon.
- The trains would have a sixty percent reduction in carbon emissions compared to current trains on the route.
If we can skim across the water in a zero-carbon high speed craft, are there any reasons we can’t cross the water in a low- or zero-carbon aircraft.
In the next few sub-sections, I’ll suggest a few air bridges.
Glasgow
Glasgow Airport could be an ideal airport for a low or zero-carbon air bridge to Northern Ireland.
- A rail link could eventually be built.
- There is a reasonable amount of traffic.
- The distance to Belfast City Airport is only 103 miles.
As the airport serves islands and other places that could be ideal low- and zero-carbon routes, I could see Glasgow becoming a hub for battery and hydrogen-powered aircraft.
Heathrow
Heathrow must prepare itself for an uncertain future.
It will be some years before a third runway is both needed and will have been constructed.
I believe the following will happen.
- Smaller up to nineteen seat low- or zero-carbon airliners will be in service by 2025.
- From around 2024, Heathrow will get requests to refuel or charge low- or zero-carbon airliners.
- Low- or-zero- carbon A 320-size airliners will be in service by 2030.
- Most ground equipment at Heathrow like tugs and fuel bowsers will be zero-carbon.
If I were Boris or Prime Minister, I would say that Heathrow could have its third runway with the following conditions.
- All aircraft using the third runway must be zero-carbon
- All air-side vehicles must be zero-carbon.
- All vehicles bringing passengers on the last mile to the airport must be zero-carbon.
- All aircraft using the airport that are not zero-carbon must use sustainable aviation fuel.
I suspect that the conditions would be met by a large margin.
When an airport knows it is effectively going to be closed, it will make sure it survives.
Liverpool
Liverpool Airport could be an ideal airport for a low or zero-carbon air bridge to the island of Ireland.
- There is a nearby Liverpool South Parkway station, with frequent services to both the local area and places further away.
- An improved London train service starts in 2022 or 2023.
- There would need to be a people mover between the station and the airport.
- The airport can probably have piped hydrogen from across the Mersey.
- There is already significant traffic to and from the island of Ireland.
- Flight times Between Liverpool and Dublin and Belfast would be under an hour.
I also feel that Liverpool could develop lots of other low- and zero-carbon routes to perhaps Cardiff, Edinburgh, Glasgow, Norwich, Southampton and the Isle of Man.
I could even see Liverpool having a Turn-Up-And-Go shuttle service to Dublin and Belfast, with small zero-carbon planes running every fifteen minutes or so.
Manston
I wouldn’t rule out Manston as a low- and zero-carbon airport for flights to the Benelux countries and Northern France and parts of Germany.
These are a few distances from Manston Airport.
- Amsterdam – 160 miles
- Brussels – 134 miles
- Cologne – 253 miles
- Dusseldorf – 234 miles
- Frankfurt – 328 miles
- Geneva – 414 miles
- Hamburg – 396 miles
- Le Touquet – 59 miles
- Lille – 49 miles
- Luxembourg – 243 miles
- Ostend – 66 miles
- Strasbourg – 339 miles
Manston’s position on the tip of Kent gives it an advantage and I think low- and zero-carbon services could reach Cologne, Frankfurt, Geneva, Hamburg and Strasbourg.
The airport also has other advantages.
- A big electrolyser to produce hydrogen is being built at Herne Bay.
- The area is rich in wind and solar energy.
- I suspect the airspace to the East of the airport isn’t very busy and short hops to the Continent could be easy to slot in.
There is a new station being built at Thanet Parkway, which is on the Ashford and Ramsgate Line, which has regular services to London, including some services on High Speed One.
This Google Map shows the location of the airport and the station.
Note.
- The runway of Manston Airport.
- The Ashford and Ramsgate Line running across the South-East corner of the map.
- The station could be built to the West of the village of Cliffsend, which is indicated by the red arrow.
- I’m sure, a people mover or a zero-carbon bus could be built to connect the station and the airport.
There would need to be improvements in the frequency of services to and from London, but I’m sure Manston Airport could become an ideal airport for low- and zero-carbon aircraft serving the near Continent.
Southampton
Southampton Airport could be the ideal design for an airport to serve an air bridge.
- The Southampton Airport Parkway station is connected to the terminal.
- The station has numerous rail services, including a fast service to and from London.
- The airport is expanding and could make sure all works are compatible with a low- and zero-carbon future.
Southampton is not ideally placed for services to Ireland, but with low- and zero-carbon aircraft it could be ideal for running services to the Channel Islands and Western France.
Other Airports
I suspect other airports will go the low- and zero-carbon route.
Conclusion
I started this post, with the intention of writing about writing about low- and zero-carbon transport between the islands of Great Britain and Ireland.
But it has grown.
I have now come to the conclusion that there are several low- and zero-carbon routes that could be developed.
The most promising would appear to be.
- London Euston and Belfast by new Class 805 train to Holyhead and then zero-carbon high speed ferry.
- London Euston and Dublin by new Class 805 train to Holyhead and then zero-carbon high speed ferry.
- Glasgow and Belfast by train to Cairnryan and then zero-carbon high speed ferry.
- Point-to-point air routes using new small nineteen seat low- or zero-carbon airliners with a range of 500 miles.
- London Euston and Belfast by new Class 807 train to Liverpool Airport and then smaller low- or zero-carbon airliner.
- London Euston and Dublin by new Class 807 train to Liverpool Airport and then and then smaller low- or zero-carbon airliner.
- Other air bridges will develop.
But I am fairly certain by the end of the decade, there will be A320-size airlines powered by hydrogen taking us to Ireland and Western Europe.
I believe that the survival and ultimate prospering of Airbus and Boeing depends on the development of a range of zero-carbon airliners.
For this reason alone, they will succeed.
Australian Coal Mine To Transform Into Pumped Hydro Facility
The title of this post, is the same as that of this article on PV Magazine.
This is the introductory paragraph.
Australian utility AGL is transforming its operations in a number of ways, from restructuring the company itself, to building energy storage facilities for flexible distribution of renewable energy into the future. The company is also planning to build a pumped-hydro facility at a disused open-cut coal mining site in eastern Australia.
It is an interesting proposition to say the least to reuse an opencast coal mine for something useful.
It would appear to be able to supple 250 MW for eight hours, which would make it a 2 GWh facility.
But then Australia is a country, that needs a lot of energy storage as they transform their economy to zero carbon.
