Sizewell C Nuclear Plant Campaigners Challenge Approval
The title of this post, is the same as that of this article on the BBC.
These three paragraphs introduce the article.
Campaigners against the Sizewell C nuclear power station have written to Business Secretary Kwasi Kwarteng to legally challenge his decision to give the scheme the go-ahead.
The £20bn project for the Suffolk coast was given government approval in July.
However, the decision was against the advice of the Planning Inspectorate and those against the scheme said the consent was therefore “unlawful”.
I summed up my attitude to nuclear power in Sizewell C: Nuclear Power Station Plans For Suffolk Submitted, where I said this.
As a well-read and experienced engineer, I am not against the technologies of nuclear power.
But I do think, by the time it is completed , other technologies like wind and energy storage will be much better value. They will also be more flexible and easier to expand, should we get our energy forecasts wrong.
I wrote that in May 2020, which was before Vlad the Mad started his war in Ukraine. So our energy forecasts are totally wrong! Thanks for nothing, Vlad!
In Plan To Build £150m Green Hydrogen Plant At Felixstowe Port, I talked about ScottishPower’s plan to build a large electrolyser at Felixstowe.
The Port of Felixstowe has in the past talked of using electricity from Sizewell C to create hydrogen.
So is the port backing another horse or just playing safe?
Plan To Build £150m Green Hydrogen Plant At Felixstowe Port
The title of this post, is the same as that of this article in The Times.
These two paragraphs introduce the project.
A £150 million green hydrogen plant is to be built at the UK’s busiest container port according to proposals by ScottishPower, it emerged yesterday.
The energy company has devised plans for a 100MW plant at the Port of Felixstowe which will provide fuel to power trains, trucks and ships.
There’s a lot more to this project than it would appear at first.
Where Will The Electrolyser Be Sited?
The Times article says this.
The site will be around the size of a football pitch, on brownfield land within the port.
I have flown my virtual helicopter over the port and there could be a couple of suitable football pitch-sized plots.
Where Will The Electricity Come From?
The East Anglia Array is a proposed massive series of offshore wind farms, which will be about thirty miles off the Suffolk coast.
Wikipedia says this about the size.
Up to six individual projects could be set up in the area with a maximum capacity of up to 7.2 GW.
But the main thing about the East Anglian Array is that it is being developed by a partnership of ScottishPower and Vattenfall.
Negotiations shouldn’t be difficult.
This Google Map shows the town of Felixstowe.
Note.
- The Ports of Felixstowe and Harwich are opposite each other on the two banks of the River Orwell.
- The power cable to the East Anglia Array comes ashore at Bawdsey in the North-East corner of the map.
- The Port of Felixstowe has two rail links, which are not electrified.
I suspect that the electric power to the electrolyser might well be routed underwater to the Port of Felixstowe either from Bawdsey or possibly direct from the wind farm.
A Meeting With A Crane Driver
I used to regularly go to Ipswich Town away matches and at one match, I met a senior crane operator from the Port of Felixstowe. We got talking about electrifying the rail link to the port and decarbonisation of the port in general.
He was adamant that electrification of the rail lines in the port, wouldn’t be a good idea as containers occasionally get dropped or crane drivers aren’t as accurate as they should be.
Hydrogen-Powered Freight Locomotives
When, I told him about the possibilities of hydrogen rail locomotives, he felt this was the way to go, as no rail electrification would be needed in the port.
Hydrogen-electric hybrid locomotives would also be able to take containers cross-country to the main electrified routes to the North and West, where they would raise their pantographs and use electric power.
How many trucks would be removed from the A14, A1 and M6?
Will Greater Anglia Convert Their Class 755 Trains to Hydrogen?
Class 755 trains have a short PowerPack in the middle and are designed for conversion to hydrogen-electric operation.
Note the PowerPack has four slots for diesel engines, batteries or hydrogen fuel-cells.
A Better Working Environment
But my fellow supporter felt the biggest gain in the port, would come with replacement or updating of all the vehicles and handling equipment, as if all these machines were hydrogen-powered, this would greatly improve the working conditions for the dock workers.
ScottishPower’s Vision
This press release on ScottishPower’s web site is entitled ScottishPower Vision For Green Hydrogen Fuels Hub At Port Of Felixstowe.
Conclusion
The Port of Felixstowe is doing the planning for this in the right way, as ensuring the hydrogen supply in the port first, is the logical way to transition to hydrogen power.
But then, I’ve watched the Port of Felixstowe grow since the 1960s and they usually get their decisions right.
The press release starts with these bullet points.
- ScottishPower explores green hydrogen at Port of Felixstowe to help decarbonise the UK’s busiest port.
- The project could help kick-start the low carbon transformation of the UK’s heavy transport sector.
- 100MW facility could deliver up to 40 tonnes of green hydrogen per day – enough to power 1300 hydrogen trucks.
- International export also being explored.
And these two paragraphs.
ScottishPower, with Hutchison Ports, is exploring the opportunity to develop, build and operate a multi-hundred MW green hydrogen production facility at the Port of Felixstowe – with the potential to decarbonise industry and transportation in the region.
Both companies have set out their vision to help create a greener port, which could provide clean fuel for customers at Britain’s busiest container port.Plans are being developed to use green hydrogen for onshore purposes, such as road, rail and industrial use, with the potential to create liquid forms, such as green ammonia or e-methanol. This could, in turn, provide clean fuels for shipping and aviation, and create opportunities for cost-effective export to international markets. The project aims to continue engineering and site development works to align with customer demand from 2025 onwards.
It is certainly a very extremely ambitious vision!
But then the county of my conception, has a tremendous determination to succeed. And often against all conventional logic!
Freightliner’s New Livery
.As I passed through Ipswich yesterday, I took these images of Freightliner’s locomotives in their new livery.
Note.
- Freightliner’s new depot on the town side of the Great Eastern Main Line appears to be fully open.
- Freightliner’s Class 90 locomotives, which they received from Greater Anglia now seem to be in the new livery.
- Freightliner’s Class 08 shunter is also shown in the new livery.
It also looked like up to four Class 90 locomotives were parked by Ipswich station.
This Google Map shows the tracks at the Western end of Ipswich station.
Note.
- The Greater Anglia Class 755 train in Platform 1 of Ipswich station.
- The two Freightliner Class 90 locomotives in the old green livery in the locomotive parking.
- I wonder, if freight trains are now changing to electric haulage after being hauled out of Felixstowe into Ipswich Yard, before continuing their onward journey.
Yesterday, by the use of Real Time Trains, I found these trains changed to electric haulage at Ipswich.
- 0250 – 436K – Felixstowe North to Garston – Changed back to diesel at Crewe.
- 0912 – 496K – Felixstowe North to Trafford Park – Changed back to diesel at Crewe.
- 0932 – 497K – Felixstowe North to Ditton
- 1113 – 412L – Felixstowe North to Trafford Park
- 2046 – 410M – Felixstowe North to Trafford Park
- 2152 – 412M – Felixstowe North to Garston – Changed back to diesel at Crewe.
These are my thoughts.
Changing Locomotives At Ipswich
It seems to take about 25 minutes to change a locomotive from diesel to electric.
At Ipswich, this seems to fairly easy.
- The freight train from Felixstowe stops in Ipswich Yard to the West of the station.
- The diesel locomotive is detached and probably moved to the yard to the South of the station.
- The electric locomotive is moved from by the station and attached to the train.
- The train goes on its way using electric traction.
All locomotive movements don’t seem to be too challenging.
Could More Electric Services Be Run?
I found these paths yesterday, where services left Felixstowe and went South to London.
- Coatbridge – 1
- Ditton – 2
- East Midlands Gateway – 1
- Garston – 2
- Hams Hall – 2
- Lawley Street – 3
- Trafford Park – 5
- Wentloog – 3
This is a total of nineteen trains and currently only six are electrified between Ipswich and London.
Would Bi-Mode Locomotives Be More Efficient?
In GB Railfreight Plans Order For Future-Proofed Bi-Mode Locomotives, I wrote about how GB Railfreight were planning to acquire a fleet of bi-mode locomotives.
In the related post, I said this.
I feel that, as the locomotive must fit current routes and schedules, so I wouldn’t be surprised to see the following specification.
- UK loading gauge.
- Co-Co
- Class 90 locomotive power and operating speed on electricity of 3.7 MW and 110 mph.
- Class 66 locomotive power and operating speed on diesel of 2.5 MW and 75 mph.
- Ability to change between electric and diesel power at speed.
- Ability to haul a heavy freight train out of Felixstowe.
- Ability to haul passenger trains.
Stadler will have one eye on the fact, that if they get this design right, this order for up to fifty locomotives could be just the start.
These locomotives would be ideal for Felixstowe to Ditton, Garston and Trafford Park.
- They would eliminate changing locomotives on these routes.
- They would reduce carbon emissions and fuel usage.
- They would be able to run at at least 100 mph on the Great Eastern and West Coast Main Lines.
They might also open up other partially electrified routes from Felixstowe via London.
Felixstowe And Wentloog
Wentloog freight terminal in South Wales.
In Movable Overhead Electrification To Decarbonise Freight, I used the Ipswich and Wentloog route to show how a long route could be decarbonised by the use of moveable electrification.
Conclusion
It looks like a philosophy is emerging to decarbonise a large proportion of freight services out of the Port of Felixstowe.
Could Norfolk And Suffolk Be Powered By Offshore Wind?
This week this article on the BBC was published, which had a title of Government Pledges £100m For Sizewell Nuclear Site.
These are the first three paragraphs.
The government is putting up £100m to support the planned Sizewell C nuclear plant in Suffolk, Business and Energy Secretary Kwasi Kwarteng has announced.
The investment marks the latest stage in efforts to build the £20bn reactor on the east coast of England.
However, it does not commit the government to approving the project, which is still subject to negotiations.
My view of the proposed Sizewell C nuclear plant is that of an engineer, who used to live within thirty minutes of the Sizewell site.
- Hinckley Point C power station, which is currently being constructed, will have a nameplate capacity of 3.26 GW.
- Sizewell C would probably be to a similar design and capacity to Hinckley Point C.
- Sizewell C would likely be completed between 2033-2036.
- Sizewell B is a 1250 MW station, which has a current closing date of 2035, that could be extended to 2055.
- East Anglia and particularly the mega Freeport East, that will develop to the South at the Ports of Felixstowe and Harwich will need more electricity.
- One of the needs of Freeport East will be a large supply of electricity to create hydrogen for the trains, trucks, ships and cargo handling equipment.
- Sizewell is a large site, with an excellent connection to the National Grid, that marches as a giant pair of overhead cables across the Suffolk countryside to Ipswich.
But.
- We still haven’t developed a comprehensive strategy for the management of nuclear waste in the UK. Like paying for the care of the elderly and road pricing, it is one of those problems, that successive governments have kept kicking down the road, as it is a big vote loser.
- I was involved writing project management software for forty years and the building of large nuclear power plants is littered with time and cost overruns.
- There wasn’t a labour problem with the building of Sizewell B, as engineers and workers were readily available. But with the development of Freeport East, I would be very surprised if Suffolk could provide enough labour for two mega-projects after Brexit.
- Nuclear power plants use a lot of steel and concrete. The production of these currently create a lot of carbon dioxide.
- There is also a large number of those objecting to the building of Sizewell C. It saddened me twenty-five years ago, that most of the most strident objectors, that I met, were second home owners, with no other connection to Suffolk.
The older I get, the more my experience says, that large nuclear power plants aren’t always a good idea.
Small Modular Nuclear Reactors
In Is Sizewell The Ideal Site For A Fleet Of Small Modular Nuclear Reactors?, I looked at building a fleet of small modular nuclear reactors at Sizewell, instead of Sizewell C.
I believe eight units would be needed in the fleet to produce the proposed 3.26 GW and advantages would include.
- Less land use.
- Less cost.
- Less need for scarce labour.
- Easier to finance.
- Manufacturing modules in a factory should improve quality.
- Electricity from the time of completion of unit 1.
But it would still be nuclear.
Wind In The Pipeline
Currently, these offshore wind farms around the East Anglian Coast are under construction, proposed or are in an exploratory phase.
- East Anglia One – 714 MW – 2021 – Finishing Construction
- East Anglia One North 800 MW – 2026 – Exploratory
- East Anglia Two – 900 MW – 2026 – Exploratory
- East Anglia Three – 1400 MW – 2026 – Exploratory
- Norfolk Vanguard – 1800 MW – Exploratory
- Norfolk Boreas – 1800 MW – Exploratory
- Sheringham Shoal/Dudgeon Extension – 719 MW – Exploratory
Note.
- The date is the possible final commissioning date.
- I have no commissioning dates for the last three wind farms.
- The East Anglia wind farms are all part of the East Anglia Array.
These total up to 8.13 GW, which is in excess of the combined capacity of Sizewell B and the proposed Sizewell C, which is only 4.51 GW.
As it is likely, that by 2033, which is the earliest date, that Sizewell C will be completed, that the East Anglia Array will be substantially completed, I suspect that East Anglia will not run out of electricity.
But I do feel that to be sure, EdF should try hard to get the twenty year extension to Sizewell B.
The East Anglia Hub
ScottishPower Renewables are developing the East Anglia Array and this page on their web site, describes the East Anglia Hub.
This is the opening paragraph.
ScottishPower Renewables is proposing to construct its future offshore windfarms, East Anglia THREE, East Anglia TWO and East Anglia ONE North, as a new ‘East Anglia Hub’.
Note.
- These three wind farms will have a total capacity of 3.1 GW.
- East Anglia ONE is already in operation.
- Power is brought ashore at Bawdsey between Felixstowe and Sizewell.
I would assume that East Anglia Hub and East Anglia ONE will use the same connection.
Norfolk Boreas and Norfolk Vanguard
These two wind farms will be to the East of Great Yarmouth.
This map from Vattenfall web site, shows the position of the two wind farms.
Note.
- Norfolk Boreas is outlined in blue.
- Norfolk Vanguard is outlined in orange.
- I assume the grey areas are where the cables will be laid.
- I estimate that the two farms are about fifty miles offshore.
This second map shows the landfall between Eccles-on-Sea and Happisburgh.
Note the underground cable goes half-way across Norfolk to Necton.
Electricity And Norfolk And Suffolk
This Google Map shows Norfolk and Suffolk.
Note.
- The red arrow in the North-West corner marks the Bicker Fen substation that connects to the Viking Link to Denmark.
- The East Anglia Array connects to the grid at Bawdsey in the South-East corner of the map.
- Sizewell is South of Aldeburgh in the South-East corner of the map.
- The only ports are Lowestoft and Yarmouth in the East and Kings Lynn in the North-West.
There are few large towns or cities and little heavy industry.
- Electricity usage could be lower than the UK average.
- There are three small onshore wind farms in Norfolk and none in Suffolk.
- There is virtually no high ground suitable for pumped storage.
- There are lots of areas, where there are very few buildings to the square mile.
As I write this at around midday on a Saturday at the end of January, 49 % of electricity in Eastern England comes from wind, 20 % from nuclear and 8 % from solar. That last figure surprised me.
I believe that the wind developments I listed earlier could provide Norfolk and Suffolk with all the electricity they need.
The Use Of Batteries
Earlier, I talked of a maximum of over 7 GW of offshore wind around the cost of Norfolk and Suffolk, but there is still clear water in the sea to be filled between the existing and planned wind farms.
Batteries will become inevitable to smooth the gaps between the electricity produced and the electricity used.
Here are a few numbers.
- East Anglian Offshore Wind Capacity – 8 GW
- Off-Peak Hours – Midnight to 0700.
- Typical Capacity Factor Of A Windfarm – 20 % but improving.
- Overnight Electricity Produced at 20 % Capacity Factor – 11.2 GWh
- Sizewell B Output – 1.25 GW
- Proposed Sizewell C Output – 3.26 GW
- Largest Electrolyser – 24 MW
- World’s Largest Lithium-Ion Battery at Moss Landing – 3 GWh
- Storage at Electric Mountain – 9.1 GWh
- Storage at Cruachan Power Station – 7.1 GWh
Just putting these large numbers in a table tells me that some serious mathematical modelling will need to be performed to size the batteries that will probably be needed in East Anglia.
In the 1970s, I was involved in three calculations of a similar nature.
- In one, I sized the vessels for a proposed polypropylene plant for ICI.
- In another for ICI, I sized an effluent treatment system for a chemical plant, using an analogue computer.
- I also helped program an analysis of water resources in the South of England. So if you have a water shortage in your area caused by a wrong-sized reservoir, it could be my fault.
My rough estimate is that the East Anglian battery would need to be at least a few GWh and capable of supplying up to the output of Sizewell B.
It also doesn’t have to be a single battery. One solution would probably be to calculate what size battery is needed in the various towns and cities of East Anglia, to give everyone a stable and reliable power supply.
I could see a large battery built at Sizewell and smaller batteries all over Norfolk and Suffolk.
But why stop there? We probably need appropriately-sized batteries all over the UK, with very sophisticated control systems using artificial intelligent working out, where the electricity is best stored.
Note that in this post, by batteries, I’m using that in the loosest possible way. So the smaller ones could be lithium-ion and largest ones could be based on some of the more promising technologies that are under development.
- Highview Power have an order for a 50 MW/500 MWh battery for Chile, that I wrote about in The Power Of Solar With A Large Battery.
- East Anglia is an area, where digging deep holes is easy and some of Gravitricity’s ideas might suit.
- I also think that eventually someone will come up with a method of storing energy using sea cliffs.
All these developments don’t require large amounts of land.
East Anglia Needs More Heavy Consumers Of Electricity
I am certainly coming to this conclusion.
Probably, the biggest use of electricity in East Anglia is the Port of Felixstowe, which will be expanding as it becomes Freeport East in partnership with the Port of Harwich.
One other obvious use could be in large data centres.
But East Anglia has never been known for industries that use a lot of electricity, like aluminium smelting.
Conversion To Hydrogen
Although the largest current electrolyser is only 24 MW, the UK’s major electrolyser builder; ITM Power, is talking of a manufacturing capacity of 5 GW per year, so don’t rule out conversion of excess electricity into hydrogen.
Conclusion
Who needs Sizewell C?
Perhaps as a replacement for Sizewell B, but it would appear there is no pressing urgency.
Direct Rail Services Disposes Of Heritage Locomotives
The title of this post, is the same as that of this article on Rail Magazine.
This is the first paragraph.
Direct Rail Services, the rail arm of Nuclear Transport Solutions (NTS), has announced details of its much-anticipated plan to sell off some of its heritage fleet of locomotives and coaching stock.
The main job of Direct Rail Services is to move nuclear fuel and other cargoes around the country in support of the UK’s nuclear industry. For this purpose, they have a substantial fleet of over fifty modern Class 66, Class 68 and Class 88 locomotives, which seem to have taken over from the heritage fleet, which are now starting to be passed on to other operators.
Direct Rail Services also tend to be the odd-job men and innovators of the traction business.
- They have provided modern motive power for both regular, charter and replacement passenger services.
- They haul freight trains for supermarkets and others.
- They sub-lease Class 68 locomotives to other operators.
- Both the Class 68 and Class 88 locomotives are 100 mph-capable, which must widen their markets.
- They have supplied locomotives for Thunderbird duties.
- They are happy to specify a new locomotive and bring it into service, as they did with the Class 68 and Class 88.
According to Wikipedia, they have issued a tender for a further ten new-build diesel-electric locomotives.
Will these be an existing design or another new design?
This is a section of the Wikipedia entry for the Class 88 locomotive.
Akin to the Class 68, the Class 88 can achieve a maximum speed of 100 mph (160 km/h), sufficient for regular passenger operations, while operating under OHLE, it has a power output of 4,000 kW (5,400 hp). Under diesel power, provided by its 12-cylinder Caterpillar C27, it has a maximum power output of 708 kW (949 hp); however, the maximum tractive effort is available in either mode. The locomotive’s engine, which is compliant with the current EU Stage IIIB emission restrictions, has limited available power as a result of the customer’s choice to give the Class 88 comparable power to a traditional Class 20.
It almost looks like a design for all purposes.
- It can pull a passenger train at 100 mph.
- With the right rolling stock, it must be able to pull a freight train at 100 mph.
- A 100 mph freight capability must be very useful on double-track electrified main lines like the East and West Coast Main Lines, where it would increase capacity.
- It probably has enough power to drag a freight train out of the depot on to an electrified main line.
- The locomotive would appear to be able to do anything that one of Direct Rail Services’s Class 20 locomotives can do, which would surely enable it to pick-up a nuclear flask from a remote power station.
- But it would also be able to transport the flask back to Cumbria using electric power, where it is available.
- In ’88’ Makes Sizewell Debut, I describe how a Class 88 locomotive moved a flask from Sizewell to Crewe.
- It is compliant with the latest emission regulations.
- It can use regenerative braking, where the electrification can handle it.
I wonder, if Direct Rail Services are going to add a locomotive to their fleet, that is capable of bringing the longest and heaviest freight trains out of the Port of Felixstowe.
- The Felixstowe Branch is a fairly flat track.
- The only moderately severe gradients ae either side of the Spring Road Viaduct.
- Some electrification could be added.
- A 100 mph freight capability would help in increasing the capacity of the Great Eastern Main Line to and from London.
The right locomotive might be able to haul smaller freight trains between Felixstowe and Peterborough.
Conclusion
There has been no news about the extra ten locomotives that Direct Rail Services will order.
The company has form in designing the right locomotive for the job they will do.
I think, that when the order is placed, it could add another type of locomotive to Direct Rail Services’s fleet.
The Route Map Of The East West Main Line
This image shows a schematic map of the East West Main Line.
Note.
- There is a lot of detail at the Eastern end. Is that the East Anglia influence in the Partnership?
- Bury St. Edmunds has been missed out. Is that the Ipswich influence in the Partnership?
- Of the four new stations only Winslow is not in Cambridgeshire. Is that the Cambridge influence in the Partnership?
It should also be noted that there are two links at the East, to the two ports of Freeport East; Felixstowe and Harwich.
Conclusion
This map makes a bold statement.

Could Class 66 Locomotives Be Converted Into Battery-Electric Locomotives?
This picture shows a Freightliner Class 66 locomotive passing through Stratford with a multimodal freight train.
These are a few thoughts on converting some of the four hundred and eighty Class 66 locomotives into battery-electric locomotives.
An Estimate Of Performance Of A Battery Electric Class 66 Locomotive
In Iron Ore Miner Orders Heavy-Haul Battery Locomotive, I said this about a UK-sized locomotive based on Wabtec’s FLXdrive battery-electric technology.
I could envisage Wabtec designing a UK-sized battery-electric locomotive with these characteristics.
- 2.5 MW power output, which is similar to a Class 66 locomotive.
- A battery size of perhaps 1.8 MWh based on Wabtec’s FLXdrive technology.
- A pantograph to charge the batteries and also power the locomotive where electrification exists.
- 75 mph operating speed.
- Ability to work in tandem with a Class 66 locomotive.
All technology is under Wabtec’s control.
This locomotive could have a range of at least fifty miles on battery power, doing the sort of duties that Class 66 locomotives do!
So it would be able to take a multimodal container train out of the Port of Felixstowe to the electrification at Ipswich.
The Class 66 Locomotive Is Diesel-Electric
The Class 66 locomotive is a diesel-electric locomotive, where the diesel engine drives an alternator, which generates electricity, which then powers the six traction motors, which are arranged, so that there is one on each of the six axles.
This should make conversion easier, as the heavy lump of the engine and the alternator would be replaced with a large number of lithium-ion batteries.
Wabtec Has A Modular Battery System
This article on Railway Age gives a lot of detail and several pictures of the modular FLXdrive battery system.
- Each module is a 4.9 kWh battery, that weighs 72.6 Kg.
- Batteries are arranged into strings, which feed the traction motors.
- There is a sophisticated control system, which ensures that a module failure doesn’t disable the locomotive.
- The battery system is air-cooled.
I would expect that Wabtec could arrange a number of modules in the stripped out body of a Class 66 locomotive.
The FLXdrive Battery System Handles Regenerative Barking
The Railway Age article says this.
Battery charging while the FLXdrive is operating occurs through regenerative dynamic braking.
This will certainly improve efficiency.
Could A Pantograph Be Fitted To A Class 66 Locomotive?
This picture of a Class 66 locomotive was taken at Peterborough.
Note the 25 KVAC overhead electrification and the gap between the wires and the roof of the locomotive.
I don’t think it would the toughest job to design a pantograph for a Class 66 locomotive.
What Would Be The Use Of A Battery Electric Class 66 Locomotive With A Fifty Mile Range?
I believe that a surprising number of duties currently handled by Class 66 locomotives could be performed by a battery-electric Class 66 locomotive.
- The locomotives would effectively be electric locomotives with a last fifty mile capability.
- The number of possible duties will increase as electrification increases.
- They would be ideal to support track maintenance activities.
- They would be a zero-carbon locomotive with a low noise footprint.
As I said earlier, they should be able to haul a heavy intermodal train out of the Port of Felixstowe.
Would A Battery-Electric And A Diesel-Electric Class 66 Locomotive Working As A Pair Be Able to Handle The Heaviest Trains?
As the Americans and Canadians have shown with more than one locomotive, where one is a battery-electric locomotive can reduce the carbon-emissions, the same rules must apply in the UK.
Conclusion
I am not a lover of the smelly, noisy and polluting diesel Class 66 locomotives, but it does look it could be possible to convert some into battery-electric locomotives.
I wouldn’t be surprised to see Wabtec convert some Class 66 locomotives into battery-electric locomotives.
I also believe, that conversion of Class 66 locomotives to battery-electric operation could be the most affordable way to help decarbonise rail freight.
Iron Ore Miner Orders Heavy-Haul Battery Locomotive
The title of this post, is the same as that of this article on Railway Gazette.
This is the first two paragraphs.
Mining company Roy Hill has ordered a Wabtec FLXdrive battery-electric heavy-haul freight locomotive. This will replace one the four ES44ACi diesel-electric locos used to haul its 2 700 m long iron ore trains, and is expected to reduce fuel costs and emissions by ‘double digit’ percentages while also cutting maintenance costs.
The locomotive is scheduled to be delivered in 2023. It will have a capacity of 7 MWh, an upgrade from the 2·4 MWh prototype which Wabtec and BNSF tested in revenue service in California earlier this year.
Note.
- It will have a 7 MWh battery.
- 2700 metres is 1.6 miles.
It looks to me, that the three diesel locomotives and one battery locomotive are arranged as a massive hybrid locomotive and I suspect that with sophisticated control systems, those double digit cuts in fuel costs and emissions would be possible.
A couple of years ago, I took this picture near Shenfield.
This double-headed train has a Class 90 electric locomotive and a Class 66 diesel locomotive at the front of a long freight train.
- The Class 90 locomotive has an TDM system for multiple working.
- The Class 66 locomotive has an AAR system for multiple working.
So does this mean that the two locomotives can’t work together, which if it does begs the question of what is happening.
- Had the Class 66 locomotive failed and Class 90 was acting as a Thunderbird?
- Was the Class 66 locomotive being moved from one depot to another for maintenance or repair?
- Was it an experiment to see if the two locomotives could work together?
I sometimes think that I didn’t see this unusual formation, but then the camera doesn’t lie.
But could we learn from what Wabtec are doing for Roy Hill in Australia?
The Class 93 Locomotive
Rail Operations Group have already ordered thirty Class 93 tri-mode locomotives from Stadler, which have following power ratings.
- Electric – 4000 kW
- Diesel – 900 kW
- Hybrid – 1300 kW
If this locomotive is capable of hauling the heaviest intermodal freight trains out of Felixstowe, Southampton and other ports and freight terminals, it could contribute to substantial reductions in the diesel fuel used and emissions.
As an example, I will use a freight train between Felixstowe North Terminal and Trafford Park Euro Terminal.
- It is a route of 280 miles.
- I will ignore that it goes along the North London Line through North London and along the Castlefield Corridor through Manchester Piccadilly station.
- There is fifteen miles without electrification at the Felixstowe end.
- There is under three miles without electrification at the Manchester end.
On this service , it could be as much as 94 % of diesel and emissions are saved, if the Class 93 locomotive can haul a heavy freight train out of Felixstowe. A few miles of strategically-placed electrification at the Ipswich end would help, if required.
It must also be born in mind, that the Class 93 locomotive is a 110 mph locomotive on electric power and could probably do the following.
- Run at 100 mph on the busy Great Eastern Main Line.
- Run at faster speeds on the West Coast Main Line.
- Fit in well with the 100 mph passenger trains, that run on both routes.
So not only does it save diesel and carbon emissions, but it will save time and make the freight train easier to timetable on a route with lots of 100 mph passenger trains.
The Class 93 locomotive looks like it could be a game-changer for long-distance intermodal freight, especially, if there were short sections of strategically-placed electrification, added to the electrified network.
Emissions could also be reduced further by using some for of sustainable fuel.
The picture shows a Class 66 locomotive, which is powered by Hydrotreated Vegetable Oil or HVO.
I can see that all diesel-powered trains and locomotives will be powered by sustainable fuels by the end of this decade.
A Wabtec Battery-Electric Locomotive
Wabtec is building a battery-electric locomotive for Roy Hill in Australia.
This article on Railway Age talks about Wabtec’s FLXdrive battery locomotives and describes some features of the locomotive for Roy Hill in Australia.
It mentions pantographs and overhead wires to charge the batteries.
- Wabtec’s prototype battery locomotive has a power output of 3.24 MW and a battery size of 2.4 MWh
- The Roy Hill battery locomotive has a power output of 3.24 MW and a battery size of 7 MWh
I could envisage Wabtec designing a UK-sized battery-electric locomotive with these characteristics.
- 2.5 MW power output, which is similar to a Class 66 locomotive.
- A battery size of perhaps 1.8 MWh based on Wabtec’s FLXdrive technology.
- A pantograph to charge the batteries and also power the locomotive where electrification exists.
- 75 mph operating speed.
- Ability to work in tandem with a Class 66 locomotive.
All technology is under Wabtec’s control.
This locomotive could have a range of at least fifty miles on battery power.
I think this locomotive could handle these routes.
- Peterborough and Doncaster via the Great Northern and Great Eastern Joint Line via Lincoln, with some form of charging at halfway.
- Felixstowe and Nuneaton, with some extra electrification at some point between Peterborough and Leicester.
- Oxford and Birmingham, with possibly some extra electrification in the middle.
One option for charging electrification, would surely be to electrify passing loops.
I think a battery-electric locomtive based on Wabtec’s FLXdrive technology could be a very useful locomotive.
Could Wabtec’s Battery-Electric Locomotive Pair-Up With A Class 66 Locomotive?
Roy Hill will use their locomotive to form a consist of three diesel locomotives and one battery locomotive to obtain double-digit savings of fuel and emissions, when hauling iron-ore trains that are 1.6 miles long on a route of 214 miles.
We don’t have massive iron-ore trains like this, but we do move huge quantities of segregates and stone around the country in trains generally hauled by Class 66 locomotives.
So could a Class 66 or another suitable locomotive be paired-up with a battery-electric locomotive to make savings of fuel and emissions?
I would suggest that if it works in Australia, the technology will probably work in the UK.
The biggest problem for Wabtec is that the heavy end of the market may well be a good one for hydrogen-powered locomotives. But Wabtec are going down that route too!
Conclusion
I am convinced that the two decarbonisation routes I have outlined here are viable for the UK.
But I also feel that locomotive manufacturers will produce hydrogen-powered locomotives.
Other companies like Alstom, Siemens and Talgo will also offer innovative solutions.
