How Defunct Coal Mines Could Heat UK Homes
The title of this post, is the same as that of this article on Mining Technology.
This is the introductory paragraph.
In a country with no operational coal mines, the UK Coal Authority has proposed to once again turn these operations to heating homes and businesses. But this time, they will not provide coal for burning. The plan, to take warm water from flooded mines, would turn an environmental problem into a community solution, and the idea is spreading.
The reason, I’m posting this is two-fold.
There was a report on this edition of Countryfile, which should be available until the end of 2022. The relevant section starts at 38.5 minutes into the program.
Charlotte Adams is featured in this report and the Countryfile program. I first came across Charlotte and her fascinating work at a lecture in 2018, which I wrote about in Can Abandoned Mines Heat Our Future?
Are First Group Moving Towards Zero-Carbon?
My post, which was entitled Suppliers Sought For New Bi-Mode Locomotives For TransPennine Express And Great Western Railway, prompted me to ask the question in the title of this post.
This factsheet for First Bus says that all their buses will be zero-carbon by 2035.
This factsheet for First Rail says this about Decarbonising Rail Travel.
FirstGroup’s ambition is to be the partner of choice for low or zero emission transport. We recently became the first UK rail and bus operator to formally commit to setting an ambitious science-based target for reaching net zero emissions by 2050 or earlier.
First Rail leads the sector in decarbonisation, including the introduction of bi-mode diesel and electric powered trains which allow us to make best use of electrified networks. We have signed up to the Government’s challenge to take all diesel-only trains out of service by 2040.
GWR has recently taken delivery of the UK’s first tri-mode train which can use overhead wires, third rail or diesel power. Sustainability is at the heart of the NRCs and both SWR and TPE will develop a decarbonisation policy and roadmap towards net zero emissions in accordance with this goal. New all-electric and bi-mode trains will be introduced by Avanti to replace diesel only trains in the current fleet.
Both these factsheets appear to have been written in 2021.
The zero-carbon status of each of First Group’s rail companies is as follows.
Avanti West Coast
The mainstay of Avanti West Coast are fifty-six Class 390 electric trains.
Twenty Class 221 diesel trains are being replaced by ten new Class 807 electric trains and thirteen new Class 805 bi-mode trains.
Great Western Railway
The mainstay of Great Western Railway are a mixture of ninety-three Class 800 and Class 802 bi-mode trains.
They also have thirty-three Class 387 electric trains working London commuter routes.
There are a large assortment of ninety-four diesel trains of various classes working rural routes and local services in Bristol, Exeter, Oxford and Plymouth. There are a lot of these trains in the UK and I suspect that a nationwide solution will be developed.
There are thirty-five Class 43 diesel locomotives, that power the shortened InterCity 125 trains in the South-West. I wrote about converting these to hydrogen in Will We See Class 43 Power Cars Converted To Hydrogen?
Four Class 57 diesel locomotives that haul the Night Riviera are covered by the request for suppliers, that prompted me to write this post.
South Western Railway
The mainstay of South Western Railway are a mixture of around three hundred electric trains.
There are also ten Class 158 diesel trains and thirty Class 159 diesel trains. There are a lot of these trains in the UK and I suspect that a nationwide solution will be developed.
TransPennine Express
The mainstay of TransPennine Express are nineteen Class 802 bi-mode trains and twelve Class 397 electric trains.
There are also fifty-one Class 185 diesel trains.
Fourteen Class 68 diesel locomotives that haul coaches are covered by the request for suppliers, that prompted me to write this post.
Hull Trains
Hull Trains have a fleet of five Class 802 bi-mode trains.
Lumo
Lumo have a fleet of five Class 803 electric trains.
The service is also sold on the basis of its low-carbon footprint.
Conclusion
First Group would appear top have a fair way to go towards full decarbonisation.
- They have around a hundred-and-thirty Hitachi bi-mode trains. Research is ongoing to replace some diesel engines with batteries.
- They have a lot of diesel trains and locomotives, that are still in front-line service.
- They have the tricky problem of the Class 43 locomotives, which I suspect will result in a nationwide solution.
But at least they have started by requesting proposals to replace the other diesel locomotives.
Aviva To Eject Company Directors If Climate Goals Are Not Met
The title of this post is the same as that of this article in The Sunday Times.
Increasingly, I am seeing company boards taking decisions, that will cut their company’s carbon footprint.
Only yesterday, I wrote Suppliers Sought For New Bi-Mode Locomotives For TransPennine Express And Great Western Railway, which was about First Group’s moves to decarbonise some of their locomotive-hauled trains.
I have also written about BHP, BP, Fortescue, Go-Ahead and Rio-Tinto taking action to decarbonise.
It does seem that some company boards are following Aviva’s guidance, but then it is in the directors own interest.
Many directors of large companies own shares and in a big public company, these are publicly traded.
I would suspect, that if a company board, do the right thing in terms of decarbonisation, that the share price will rise.
So by following the accepted climate science, they are actually helping themselves.
If they don’t believe that, then aggressive shareholders from Norwich will punish them.
The Future Of The Class 68 Locomotives
This post has been brought on by the comments to two posts I have written today.
- Direct Rail Services Disposes Of Heritage Locomotives
- Suppliers Sought For New Bi-Mode Locomotives For TransPennine Express And Great Western Railway
Both Direct Rail Services and TransPennine Express are major users of Class 68 locomotives, with each having a fleet of fourteen locomotives.
In addition, Chiltern Railways has a smaller fleet of six locomotives.
- Direct Rail Services use their locomotives for various passenger and freight duties, including the important one of moving nuclear material around the country.
- TransPennine Express use their locomotives on their passenger services across the North of England.
- Chiltern Railways use their locomotives on their passenger services between London and Birmingham and sometimes Oxford.
The design was a bespoke one by Stadler for Direct Rail Services and the first one entered service in 2014.
The picture shows one of TransPennine’s Class 68 locomotives at Scarborough. As the picture shows, they are a smart and purposeful-looking locomotive, that wouldn’t look out of place in the right livery on the front of the Royal Train.
It has some good features.
- It is a 100 mph locomotive.
- It seems to be well-liked by operators.
- It can haul both passenger and freight trains.
- It can act as a Thunderbird or rescue locomotive.
But they have three problems; emissions, noise and diesel.
This is from Wikipedia.
The locomotive’s propulsion system is compliant with Stage III A of the European emission standards, but not the more stringent Stage III B requirements.
But noise is a another problem and this has caused council action in Scarborough.
More important than emissions or noise, is the fact, that the locomotive is diesel-powered, so the fleet will probably have to be retired from the railway, at a time, when there is still useful life left in the locomotives.
The Class 68 locomotive is a member of the Stadler Eurolight family, of which there are three versions.
All follow similar design principles, differing mainly in dimensions, with Spain, Taiwan and the UK ordering upwards of twenty-thirty locomotives.
The UKLight branch of the family has two other members.
The Class 88 locomotive is an electro-diesel version of the Class 68 locomotive and the development of the design is described in this extract from the Class 88 locomotive’s Wikipedia entry.
Amid the fulfillment of DRS’ order for the Class 68, Stadler’s team proposed the development of a dual-mode locomotive that could be alternatively powered by an onboard diesel engine or via electricity supplied from overhead lines (OHLE). Having been impressed by the concept, DRS opted to place an order for ten Class 88s during September 2013. Having been developed alongside the Class 68, considerable similarities are shared between the two locomotives, amounting to roughly 70 percent of all components being shared.
According to Wikipedia, the type had a smooth entry into service.
The Class 93 locomotive will be the next development of the UKLight branch of the family, when it is delivered in 2023.
It will be a tri-mode locomotive, that will be capable of being powered by 25 KVAC overhead electrification, an onboard diesel engine and batteries.
It will be a 110 mph locomotive.
It can haul both passenger and freight trains.
Rail Operations Group have ordered 30 locomotives.
This is the first paragraph of the section in Wikipedia called Specification.
The Class 93 locomotive has been developed to satisfy a requirement for a fast freight locomotive that uses electric power while under the wires, but is also capable of self-powered operations. Accordingly, it is capable of running on diesel engines, from overhead wires, or from its onboard batteries. These batteries, which occupy the space used for the braking resistors in the Class 88, are charged via the onboard transformer or regenerative braking; when the batteries are fully charged, the locomotive only has its friction brakes available. The diesel engine is a six-cylinder Caterpillar C32 turbocharged power unit, rated at 900 kW, conforming with the EU97/68 stage V emission standard. The batteries units are made of Lithium Titanate Oxide and use a liquid cooling solution, enabling rapid charge and discharge.
It is a truly agnostic locomotive, that can take its power from anywhere.
The last paragraph of the specification compares the locomotive to the Class 66 locomotive.
In comparison with the Class 66, the Class 93 can outperform it in various metrics. In addition to a higher top speed, the locomotive possesses greater acceleration and far lower operating costs, consuming only a third of the fuel of a Class 66 along with lower track access charges due to its lower weight. ROG has postulated that it presents a superior business case, particularly for intermodal rail freight operations, while also being better suited for mixed-traffic operations as well. Each locomotive has a reported rough cost of £4 million.
It is no ordinary locomotive and it will change rail freight operations in the UK.
I have a feeling that the Class 93 locomotive could be a lower-carbon replacement for the Class 68 locomotive.
But I also believe that what Stadler have learned in the development of the Class 93 locomotive can be applied to the Class 68 locomotive to convert them into zero-carbon locomotives.
It may be just a matter of throwing out the diesel engine and the related gubbins and replacing them with a large battery. This process seems to have worked with Wabtec’s conversion of diesel locomotives to FLXdrive battery-electric locomotives.
Oman And BP Sign Renewable Hydrogen Partnership On Mega-Gigawatt Scale
The title of this post, is the same as that of this article on Hydrogen Fuel News.
This is the introductory paragraph.
Oman has announced that it has entered into an agreement with BP, in which the energy giant will support the country’s development of mega-gigawatts of renewable hydrogen and energy by 2030.
Wind and solar power will be developed on 8,000 square kilometres of land.
Suppliers Sought For New Bi-Mode Locomotives For TransPennine Express And Great Western Railway
The title of this post, is the same as that of this article on Rail Advent.
These three paragraphs give a summary of the proposed fleet of locomotives required by First Group for their two operations.
TransPennine Express is looking for expressions of interest from suppliers for a fleet of at least 15 bi-mode locomotives for use on with its Mk5 carriages.
The provision released by First Group is for up to 30 bi-mode locomotives, with an additional 5 for use on Great Western Railway’s Sleeper Service.
The operators say that the new locomotives must have the capability to be powered by overhead wires as well as being able to operate with an alternate traction mode, IE Diesel or Battery, where routes are not yet electrified or for use as a contingency.
I have also read the detailed proposal, which can be downloaded from this page of the First Group web site.
- The locomotives must be capable of hauling a train at 100 mph.
- First Group are putting a high emphasis on environmental impact of the locomotives.
- The locomotives must be compatible with the latest emission regulations.
- The locomotives must be low-noise.
- The locomotives must be capable of hauling seven coaches, including a driving van trailer.
Nothing in the request for proposals would appear to be too challenging.
I have some thoughts.
The Number Of Locomotives For TransPennine Express
Currently, TransPennine Express has a fleet of fourteen Class 68 locomotives and enough coaches and driving van trailers to create thirteen rakes of Mark 5A coaches.
So why do TransPennine Express talk of up to thirty locomotives?
- Fifteen locomotives would handle the current services, so thirty could cover new services or more services on the current locomotive-hauled routes.
- Manchester Airport and Cleethorpes and Manchester Piccadilly and Hull are run by Class 185 diesel trains, which will need replacing at some future time.
- First Group probably know the costs of running Class 802 trains and locomotives with rakes of coaches better than anyone , so are they thinking about swapping some Class 802 trains for locomotives with rakes of coaches?
The last point would be one for the accountants.
But I am led to the conclusion, that TransPennine Express could be expanding and also decarbonising the long routes still operated by Class 185 trains.
The Number Of Locomotives For Great Western Railway
Currently, Great Western Railway has a fleet of four Class 57 locomotives to haul the Night Riviera.
Five replacement locomotives would probably be enough.
Could A Battery-Electric Locomotive Handle The TransPennine Express Requirement?
Currently, there are gaps in the electrification of the TransPennine network.
- Manchester Victoria and Stalybridge – 7.7 miles – Electrification in progress
- Stalybridge and Huddersfield – 18 miles
- Huddersfield and Dewsbury – 8 miles – Electrification in progress
- Dewsbury and Leeds – 9.1 miles
- Leeds and York – 25.6 – Electrification in progress
- Northallerton and Redcar – 28.8 miles
- Manchester Piccadilly and Stalybridge – 7.5 miles
- Leeds and Hull – 51.8 miles
- Doncaster and Cleethorpes – 72.1 miles
- Scarborough and York – 42 miles
- Doncaster and Sheffield – 18.7 miles
- Sheffield and Stockport – 36.8 miles – Rumoured to be electrified
Note.
- Many gaps are quite small.
- The longest gaps are on easy routes.
- Sheffield will be electrified for the Midland Main Line.
- A length of electrification at Scunthorpe could ease Doncaster and Cleethorpes.
I feel that a battery-electric locomotive with a range of a hundred miles hauling seven coaches, would be able to handle all the TransPennine routes.
If the train could run the routes with an electricity consumption of 4 kWh per vehicle-mile, seven coaches would need 4 * 8 * 100 = 3.2 MWh of battery storage.
Note.
- A 3.2 MWh battery would weigh around 3.2 tonnes, which would be less than the diesel engine in a Class 68 locomotive.
- Regenerative braking to batteries could be used to improve range.
- In How Much Power Is Needed To Run A Train At 125 Or 100 mph?, I calculated that an InterCity 125 needs 1.81 kWh per vehicle mile to maintain 100 mph.
I am fairly certain, that a well-designed efficient battery-electric locomotive would be able to handle all of the routes for TransPennine Express.
Could A Battery-Electric Locomotive Handle The Night Riviera?
I have just looked up the Southbound Night Riviera on Real Time Trains.
- It leaves Paddington at 23:50.
- It is typically eight coaches and a Class 57 locomotive.
- The train is planned to run at 75 mph.
- The first 53 miles between Paddington and Newbury are electrified.
- There is a stop of one hour and 39 minutes at Exeter.
- Newbury and Exeter is 120.4 miles
- Exeter and Penzance is 130.8 miles
The Northbound Night Riviera only has a five minute stop at Exeter and two minutes stops at Totnes, Newton Abbott and Taunton.
A battery-electric locomotive would need a range of 140 miles hauling eight coaches.
- Some stops like Plymouth may need to be lengthened by a few minutes to charge the batteries.
- Extra stops of perhaps five minutes could be added to top-up the batteries.
- The train would be limited to 75 mph, which would improve efficiency.
- It might even be prudent to electrify the uphill track of some of the steeper parts of the route.
But think of the marketing advantages of a zero-carbon sleeper train!
Conclusion
When I saw First Group’s proposals, I thought that they were over ambitious.
But after doing a few simple calculations, I think they can decarbonise some, but not all of the TransPennine Express services and the Night Riviera.
Quiet Battery-Powered River Ferries To Serve Battersea Power Station Pier
The title of this post, is the same as that of this article on Nine Elms.
These two paragraphs give the story and explain the operation of the new boats.
Passengers using Battersea Power Station pier will soon be boarding the UK’s first hybrid high speed passenger ferries using battery power.
Uber Boat by Thames Clippers are building two new vessels which will operate solely on battery power when travelling between Tower and Battersea Power Station piers – and recharge while using biofuelled power when sailing further east and west outside their central London route.
They will join the fleet in the Autumn.
There is also this environmental statement from Thames Clipper.
Uber Boat by Thames Clippers is committed to achieving net zero with all new builds by 2025 and for its wider fleet, infrastructure and environmental footprint by 2040.
That sounds very good to me.
Conclusion
I suspect that this policy will lead to increasing use on London’s river transport system.
I’d also like to see Thames Clipper better integrated with the Overground, Underground and the buses. Some of the walking routes could be improved and have better signage.
I also think, that the Thames Clipper would benefit, if the Freedom Pass could be linked to a credit card, so that Freedom Pass holders would only need to use one card to use all of London’s transport systems.
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.
False Banana: Is Ethiopia’s Enset ‘Wondercrop’ For Climate Change?
The title of this post, is the same as that of this article on the BBC.
This is the introductory paragraph.
Scientists say the plant enset, an Ethiopian staple, could be a new superfood and a lifesaver in the face of climate change.
A new study is saying, that the plant could be used to feed 100 million people in a warming world.
It looks like the study was done in an Ethiopian University, which is surely a heartwarming thing.
This is said about how enset is used for food.
Enset or “false banana” is a close relative of the banana, but is consumed only in one part of Ethiopia.
The banana-like fruit of the plant is inedible, but the starchy stems and roots can be fermented and used to make porridge and bread.
I’m not sure, but I seem to remember that porridge is a major food in Africa.
It is certainly a fascinating good news story. in several ways from Africa.
What is Mineral Carbonation And How Could It Transform The Building Industry?
The title of this post, is the same as that of this article on AZO CleanTech.
This is the introductory paragraph.
Natural carbonates have been prime building materials for centuries, but synthetic carbonates are a modern, robust building material, created via mineral carbonation.
The article is a must-read introduction to this fascinating Australian technology, which could be very important in combating climate change.
There is also an explanatory video, which is worth a watch.
