Carew Castle Express Unveiled In Carmarthen
The title of this post, is the same as that of this article on Rail UK.
These are the first two paragraphs.
The ‘Carew Castle Express’ has been unveiled to mark the introduction of brand-new Transport for Wales (TfW) trains between Swansea and Carmarthen.
Named as part of TfW’s Magnificent Train Journey competition, the name ‘Carew Castle Express’ was chosen by year 5 pupil Rhys Protheroe from Johnstown Primary School in Carmarthen.
But perhaps, this extract is the most significant statement in the article.
Soon every service west of Carmarthen will be on one of the brand-new trains.
Alexia Course, chief commercial officer for TfW, said: “We’re excited to be running our brand-new trains in West Wales and we’re adding more to our network every few weeks.
CAF and TfW don’t seem to be hanging about in getting these new trains into service.
But then, I suspect some of the trains they replace, will be going to the scrapyard in Newport.
How Will These Trains Be Decarbonised?
My one worry is that these Class 197 trains and the similar Class 195 trains at Northern and the Class 196 trains at West Midlands Trains are diesel powered.
Nothing has been said about how these 141 trains will be decarbonised.
But all three fleets have the same Rolls-Royce mtu 6H 1800 R85L engines, so at least one solution will fit all!
A Thought About LNER’s New Trains
These trains appear to have been delivered quickly.
Did this influence the decision of LNER to buy CAF trains for their fleet expansion?
First Tri-Mode Long Distance Trains For The East Coast Main Line
The title of this post, is the same as that of this press release from LNER.
This is the sub-heading.
London North Eastern Railway (LNER) is pleased to confirm that CAF has been named as the successful bidder to deliver a fleet of 10 new tri-mode trains for LNER. Porterbrook has been chosen as the financier of the new fleet. The trains will be able to operate in electric, battery or diesel mode.
These are the first two paragraphs.
Benefits of tri-mode trains range from a reduction in emissions, particulates, noise and vibration pollution, lower maintenance and operating costs and upgradeable technology, with an expected increase in range and performance as technology develops further. Battery power reduces the need to use diesel traction in areas where overhead powerlines are not available.
Complementing the modern Azuma fleet of 65 trains, the new ten-coach trains will help LNER achieve its vision of becoming the most loved, progressive and trusted train operator in the UK, delivering an exceptional service for the customers and communities served along its 956-mile network.
I have a few thoughts.
Will The Trains Have Rolls-Royce mtu Diesel Engines?
Consider.
- CAF’s Class 195, 196 and 197 Civity trains for the UK all have Rolls-Royce mtu diesel engines.
- Porterbrook are headquartered in Derby.
- Rolls-Royce are headquartered in Derby.
- In Rolls-Royce And Porterbrook Agreement Will Drive Rail Decarbonisation, I talked about how the two companies were planning to decarbonise trains using techniques like mtu Hybrid PowerPacks and hydrogen fuel cells.
I would think it very likely that the new trains will have Rolls-Royce mtu engines.
Will The Trains Have Rolls-Royce mtu Hybrid PowerPacks?
It was in 2018, that I first wrote about mtu Hybrid PowerPacks in Rolls-Royce And Porterbrook Launch First Hybrid Rail Project In The UK With MTU Hybrid PowerPacks.
- Examples of these power packs are now running in Germany, Ireland and the UK.
- The mtu Hybrid PowerPack how has its own web site.
- There is also this YouTube video.
- If CAF use off-the-shelf mtu Hybrid PowerPacks in their Civity trains, there is one big massive plus – They don’t have to develop the complicated control software to get a combination of diesel engines and batteries to perform as immaculately as Busby Berkeley’s dancers or a Brigade of Guards.
- The mtu Hybrid PowerPacks also have a big plus for operators – The batteries don’t need separate charging infrastructure.
- In Rolls-Royce Releases mtu Rail Engines For Sustainable Fuels, I talk about how mtu engines can run on sustainable fuels, such as biodiesel or HVO.
I think it is extremely likely that CAF’s new trains for LNER will be powered by mtu Hybrid PowerPacks.
Class 800 And Class 397 Trains Compared
The Class 800 train is LNER’s workhorse to Scotland from London.
The Class 397 train used by TransPennine Express, is a 125 mph Civity train.
Differences include.
- The Class 800 train can run at 140 mph, where the signalling allows, but is the Class 397 train only capable of 125 mph?
- The Class 397 train accelerate at 0.92 m/s², whereas the Class 800 train can only manage 0.7 m/s².
- The Hitachi train has 14 % more seats, 36 First and 290 Standard as opposed to 22 First and 264 Standard in five-car trains.
I will add to this list.
Will The New Trains Be Capable Of 140 mph Running?
As the East Coast Main Line is being fully digitally signalled to allow 140 mph running of the numerous Hitachi expresses on the route, I wouldn’t be surprised to see, that the new CAF trains will be capable of 140 mph.
In this article on Modern Railways, which is entitled LNER Orders CAF Tri-mode Sets, this is said.
The new fleet will be equipped with CAF Signalling’s European Rail Traffic Management System digital signalling. This will align with the East Coast Digital Programme, which aims to introduce European Train Control System (ETCS) on the southern stretch of the East Coast main line from King’s Cross to Stoke Tunnel by 2029.
Later in the article this is said.
LNER has retained 12 ‘91s’ hauling eight rakes of Mk 4s, and the rollout of ETCS is another reason the operator has sought to order the replacement fleet. LNER’s passenger numbers have rebounded more quickly than other operators post-Covid, which has helped make the case for confirming the order.
This does seem sensible.
What Will Be The Range Of The CAF Trains Without Electrification?
The longest LNER route without electrification is the Northern section of the Inverness service between Inverness and Dunblane, which is 146.1 miles. There are also eight stops and some hills.
In Edinburgh to Inverness in the Cab of an HST, there’s a video of the route.
I’m sure that even, if they don’t normally run the new trains to Inverness, being able to do so, could be useful at some point.
It should be noted that the Guinness World Record for battery-electric trains is 139 miles, which is held by a Stadler Akku.
I am left with the conclusion that London and Inverness needs a tri-mode train or lots of electrification. Did this rule out Hitachi?
The Number Of Trains Ordered
The Modern Railways article says this about the number of trains.
The contract includes an eight-year maintenance services agreement with an option to extend; CAF says the order value, including maintenance, exceeds €500 million. When the tender was published the intention was to include an option for five additional sets; LNER confirmed to Modern Railways there is an option to purchase additional sets on top of the base order of 10.
Can we assume this means that other trains will be ordered, if the trains are a success?
Can These New CAF Trains Be Made Net Zero?
This is a paragraph, in the LNER press release.
This new fleet of trains will keep LNER on track to reduce its emissions by 67 per cent by 2035 and be net zero by 2045. LNER has already reduced carbon emissions by 50 per cent compared with 2018/19. Per mile, LNER trains produce 15 times less carbon emissions than a domestic flight.
As the new CAF trains will probably have a service life of at least forty years, there must be some way, that these new trains can be made net zero.
Consider.
- I am absolutely certain, that the new CAF trains will have Rolls-Royce mtu diesel engines.
- LNER’s existing Class 800 and 801 trains have Rolls-Royce mtu diesel engines.
Rolls-Royce mtu according to some of Rolls-Royce’s press releases appear to be developing net zero solutions based on hydrogen or net zero fuels.
This press release from Rolls-Royce is entitled Rolls-Royce Successfully Tests mtu Engines With Pure Hydrogen, suggests that Rolls-Royce mtu are working on a solution.
Routes They Will Serve
The Modern Railways article says this about the routes to be served.
Modern Railways understands the new fleet will be maintained at Neville Hill depot in Leeds and, like the ‘225’ sets, will be used predominantly on services between London and Yorkshire, although unlike the ‘225s’ the tri-modes, with their self-power capability, will be able to serve destinations away from the electrified network such as Harrogate and Hull.
Note.
- This surprised me, as I’d always expected the Yorkshire routes will be served by Hitachi battery-electric trains.
- But it does look that both Harrogate and Hull stations, have long enough platforms to hold a ten-car train.
- With their tri-mode technology, it also looks like the CAF trains won’t be needed to be charged before returning to London.
The last point would enable them to try out new routes.
These are distances from the electrification of the East Coast Main Line of the destinations that LNER served, where there is not full electrification.
- Aberdeen via Ladybank – 91.4 miles
- Carlisle via Skipton – 86.8 miles
- Cleethorpes via Newark and Lincoln – 63.9 miles
- Harrogate via Leeds – 18.3 miles
- Huddersfield via Leeds – 17.2 miles
- Hull via Temple Hirst junction – 36.1 miles
- Inverness via Dunblane – 146.1 miles
- Lincoln via Newark – 16.7 miles
- Middlesbrough via Northallerton – 22.2 miles
- Scarborough via York – 42.1 miles
- Sunderland via Northallerton – 47.4 miles
Note.
- The first place after the ‘via’ is where the electrification ends.
- Carlisle could be a possibility during High Speed Two upgrading of the West Coast Main Line or for an enthusiasts’ special or tourist train.
- Cleethorpes is a possible new service for LNER. I wrote about this in LNER To Serve Cleethorpes.
- Scarborough must be a possible new service for LNER.
- All stations can take ten-car trains, with the possible exception of Middlesbrough, which is currently being upgraded.
- Huddersfield and Leeds is being electrified under the TransPennine Upgrade.
This would appear to show that LNER need enough bi-mode or tri-mode trains to run services to Aberdeen, Cleethorpes, Harrogate, Hull, Inverness, Lincoln, Middlesbrough and Sunderland.
But.
- It would appear that the initial batch of trains, will not be serving the North of Scotland.
- Aberdeen and Inverness could be served, when there is enough electrification at the Southern end.
I am also fairly sure, that no significant infrastructure is required.
Do Hitachi Have A Problem?
I am starting to wonder, if Hitachi are having trouble with the designing and building of their battery packs.
- It’s not like Hitachi to allow someone to run off with a €500 million contract from under their nose.
- Are they short of capacity to build the trains at Newton Aycliffe?
But then they’re probably up to their elbows in work on the High Speed Two Classic-Compatible trains.
Are There Any Other Routes, Where The New CAF Trains Could Be Employed?
The trains would certainly be suitable for these routes.
- Chiltern – InterCity services.
- CrossCountry Trains – Fleet replacement
- Grand Central Trains – Fleet replacement
- Grand Union Trains – For Carmarthen and Stirling open access services.
- Great Western Railway – Replacing Castles in the South West.
- ScotRail – Replacing Inter7City trains.
- South Western Railway – Basingstoke and Exeter St. Davids and other routes.
Note.
- CAF could sell a lot of trains.
- I estimate that fleet replacement for Grand Central Trans would cost around €350 million
- The specification would vary according to the route.
Could CAF have got the LNER order, because they have the capacity in the Newport factory?
Conclusion
It looks like CAF have done a good job in designing the trains.
I’m also fairly sure that CAF are using Rolls-Royce mtu PowerPacks.
Cummins And Leclanché S.A. To Collaborate On Lower-Emissions Solutions For Use In Marine And Rail Applications
The title of this post, is the same as that of this press release from Cummins.
This is the introductory paragraph.
Today, global power and technology leader, Cummins Inc., and leading provider of energy storage solutions, Leclanché S.A, announced the signing of a Memorandum of Understanding (MOU). The collaboration represents a significant step forward in providing customers with a broader portfolio of integrated power solutions.
Effectively, this means that all customer requirements for integrated power solutions can be met by the two companies.
It appears to me, that if someone wanted Cummins to provide a system like the HybridFLEX train, I wrote about in Rolls-Royce And Porterbrook Launch First Hybrid Rail Project In The UK With MTU Hybrid PowerPacks, then Cummins and Leclanché have the technology between them to create a system.
In the UK, Cummins power these relatively-modern trains.
- Class 175 – 9 x two-car and 15 x three-car.
- Class 180 – 1 x four-car and 12 x five-car.
- Class 185 – 51 x three-car.
- Class 220 – 34 x four-car.
- Class 221 – 24 x four-car and 18 x five-car.
- Class 222 – 23 x five-car and 4 x seven-car.
Note.
- They are capable of 100 mph or 125 mph.
- Condition of the interiors is generally good.
- There are 9 x two-car, 66 x three-car, 59 x four-car, 53 five-car and 4 x seven-car.
- In Grand Central DMU To Be Used For Dual-Fuel Trial, I described innovative fuel trails in a Class 180 train.
- There could be other similar trains in Europe and around the world.
How many of these trains could be converted to hybrid operation, if Cummins and Leclanché were to create their version of the mtu Hybrid PowerPack?
Conclusion
Have Cummins and Leclanché decided that if a hybrid approach is good enough for Rolls-Royce mtu, then it’s good enough for them?
Centrica Business Solutions Begins Work On 20MW Hydrogen-Ready Peaker In Redditch
The title of this post, is the same as that as this news item from Centrica Business Systems.
This is the sub-heading.
Centrica Business Solutions has started work on a 20MW hydrogen-ready gas-fired peaking plant in Worcestershire, as it continues to expand its portfolio of energy assets.
These three paragraphs outline the project.
Centrica has purchased a previously decommissioned power plant in Redditch, and is set to install eight UK assembled containerised engines to burn natural gas.
Expected to be fully operational later this year, the peaking power plant will run only when there is high or peak demand for electricity, or when generation from renewables is low. The Redditch project will have the capacity to power the equivalent of 2,000 homes for a full day when required, helping to maintain stability and reliability on the grid.
The engines will also be capable of burning a blend of natural gas and hydrogen, futureproofing the site and helping the UK transition towards a decarbonised energy system.
- The original power station had Rolls-Royce generators.
- Cummins and Rolls-Royce mtu and possibly other companies can probably supply the dual fuel generators.
- Cummins have received UK Government funding to develop hydrogen-powered internal combustion engines.
- This press release from Cummins, which is entitled Dawn Of A New Chapter From Darlington, gives more details on Cummins’ plans for the Darlington factory and hydrogen.
Given that Cummins manufactured sixty-six thousand engines in Darlington in 2021 and it is stated that these containerised engines will be assembled in the UK, I feel, that these engines may be from Cummins.
Centrica’s Plans
This paragraph in the Centrica Business Systems news item, outlines their plans.
The Redditch peaking plant is part of Centrica’s plans to deliver around 1GW of flexible energy assets, that includes the redevelopment of several legacy-owned power stations, including the transformation of the former Brigg Power Station in Lincolnshire into a battery storage asset and the first plant in the UK to be part fuelled by hydrogen.
As Redditch power station is only 20 MW, Centrica could be thinking of around fifty assets of a similar size.
Brigg Power Station
The Wikipedia entry for Brigg Power station gives these details of the station.
- The station was built in 1993.
- It is a combined cycle gas turbine power station.
- The primary fuel is natural gas, but it can also run on diesel.
- It has a nameplate capacity of 240 MW.
Brigg power station is also to be used as a test site for hydrogen firing.
This news item from Centrica is entitled Centrica And HiiROC To Inject Hydrogen At Brigg Gas-Fired Power Station In UK First Project.
These paragraphs from the news item explains the process.
The 49MW gas fired plant at Brigg is designed to meet demand during peak times or when generation from renewables is low, typically operating for less than three hours a day. Mixing hydrogen in with natural gas reduces the overall carbon intensity.
It’s anticipated that during the trial, getting underway in Q3 2023, no more than three per cent of the gas mix could be hydrogen, increasing to 20% incrementally after the project. Longer term, the vision is to move towards 100% hydrogen and to deploy similar technology across all gas-fired peaking plant.
HiiROC’s proprietary technology converts biomethane, flare gas or natural gas into clean hydrogen and carbon black, through an innovative Thermal Plasma Electrolysis process. This results in a low carbon, or potentially negative carbon, ‘emerald hydrogen’.
Because the byproduct comes in the form of a valuable, solid, pure carbon it can be easily captured and used in applications ranging from tyres, rubbers and toners, and in new use cases like building materials and even as a soil enhancer.
It looks to me, that HiiROC are using an updated version of a process called pyrolysis, which is fully and well-described in this Wikipedia entry. This is the first paragraph.
The pyrolysis (or devolatilization) process is the thermal decomposition of materials at elevated temperatures, often in an inert atmosphere. It involves a change of chemical composition. The word is coined from the Greek-derived elements pyro “fire”, “heat”, “fever” and lysis “separating”.
Pyrolysis is more common than you think and is even used in cooking to do things like caramelise onions. This is a video of a chef giving a demonstration of caramelising onions.
On an industrial scale, pyrolysis is used to make coke and charcoal.
I came across pyrolysis in my first job after graduating, when I worked at ICI Runcorn.
ICI were trying to make acetylene in a process plant they had bought from BASF. Ethylene was burned in an atmosphere, that didn’t have much oxygen and then quenched in naphtha. This should have produced acetylene , but all it produced was tonnes of black soot, that it spread all over Runcorn.
I shared an office with a guy, who was using a purpose-built instrument to measure acetylene in the off-gas from the burners.
When he discovered that the gas could be in explosive limits, ICI shut the plant down. The Germans didn’t believe this and said, that anyway it was impossible to do the measurement.
ICI gave up on the process and demolished their plant, but sadly the German plant blew up.
It does look like HiiROC have tamed the process to be able to put hydrocarbons in one end and get hydrogen and carbon black out the other.
I wonder how many old and possibly dangerous chemical processes can be reimagined using modern technology.
It certainly appears that Centrica are not holding back on innovation.
Conclusion
I’ve never run a large electricity network. Not even a simulated one.
But I’m fairly sure that having a large number of assets of different sizes, that can be optimised to the load and the fuel available, creates a more reliable and efficient network.
Heavy energy users may even have their own small efficient power station, that is powered by gases piped from the local landfill.
Universal Hydrogen And Railway Locomotives
On the product page of the Universal Hydrogen web site, there is a section, which is entitled Other Transportation Applications, where this is said.
Our lightweight, aviation-grade modular hydrogen capsules can be used in a wide range of transportation applications where weight, safety, and speed of refueling are important. We are working with partners in automotive, heavy equipment, maritime, and railroad domains. If you have an application that can benefit from our global modular green hydrogen distribution network, please get in touch!
I believe that the railway locomotive of the future will be hydrogen-electric. And so do some of the UK’s rail freight companies, judging, by some of their press releases.
- It would have an electric transmission. like most locomotives today, such as the UK’s Class 66, Class 68, Class 70, Class 88, Class 93 and the upcoming Class 99 locomotives.
- It will be able to use 25 KVAC overhead electrification, where it exists.
- Hydrogen-power will be used, where there is no electrification.
The lowest-carbon of the locomotives, that I listed, will probably be the Class 99 locomotive.
- Thirty have been ordered by GB Railfreight, from Swiss company; Stadler.
- The locomotives will be built at Valencia in Spain.
- It will have up to 6 MW, when running using electrification.
- It will have up to 1.6 MW, when running using a Cummins diesel, with a rating of 2,150 hp.
- Because a proportion of UK freight routes are electrified, it is likely that these locomotives will substantially reduce carbon emissions for many locomotive-hauled operations.
It should be noted that Cummins are heavily into hydrogen and their philosophy seems to embrace families of engines, which are identical below the cylinder head gasket, but with appropriate cylinder heads and fuel systems, they can run on diesel, natural gas or hydrogen.
I wouldn’t be surprised to find out that the Class 99 locomotive will have a diesel engine, that has a hydrogen-powered sibling under development at Cummins.
With perhaps a power on hydrogen of about 2.5 MW, these zero-carbon locomotives would be able to handle upwards of ninety percent of all heavy freight trains in the UK.
These are further thoughts.
Alternatives To Cummins Hydrogen Internal Combustion Engines
There are two main alternatives, in addition to similar engines from companies like Caterpillar, JCB, Rolls-Royce mtu and others.
- Fuel cells
- Gas-turbine engines.
Note.
- Universal Hydrogen and others have fuel cells, that can probably deliver 2.5 MW.
- Universal Hydrogen use Plug Power fuel cells.
- Rolls-Royce have developed a 2.5 MW electrical generator, based on the engine in a Super Hercules, that is about the size of a typical beer-keg. I wrote about this generator in What Does 2.5 MW Look Like?.
Cummins may be in the pole position with Stadler, but there are interesting ideas out there!
Cummins have also indicated, they will build hydrogen internal combustion engines at Darlington in the UK.
Would One Of Universal Hydrogen’s Hydrogen Capsules Fit In A Railway Locomotive?
These are various widths.
- Class 66 locomotive – 2.63 metres.
- ATR72 airliner – 2.57 metres.
- DHC Dash-8 airliner – 2.52 metres
- Class 43 power car – 2.74 metres
I suspect that even if it was a bit smaller a hydrogen capsule could be made for a UK locomotive.
How Big Is The Market?
The UK has around five hundred diesel railway locomotives.
Rolls-Royce Successfully Tests mtu Engines With Pure Hydrogen
The title of this post, is the same as that of this press release from Rolls-Royce.
These are the two bullet points.
- mtu gensets and cogeneration units to be further developed for 100% hydrogen use
- First use in the new CO2-neutral container terminal in the German inland port of Duisburg
This is the first paragraph.
Rolls-Royce (LSE: RR., ADR: RYCEY) today announces that it has conducted successful tests of a 12-cylinder gas variant of the mtu Series 4000 L64 engine running on 100% hydrogen fuel. The tests, carried out by the Power Systems business unit, showed very good characteristics in terms of efficiency, performance, emissions and combustion. These tests mark another important step towards the commercial introduction of hydrogen solutions to meet the demand of customers for more sustainable energy.
Note.
- Rolls-Royce mtu have converted and tested a natural gas version of the Series 4000 L64 engine.
- The Class 43 power cars used in the iconic InterCity 125 train and powered by mtu V16 4000 R41R engines.
Are the two engines related? If so, can Rolls-Royce mtu build a hydrogen engine that could power an InterCity 125?
It was a rapid development.
Andrea Prospero, an engineer at Rolls-Royce responsible for the development of the hydrogen engine, is quoted as saying.
We are very pleased with the rapid progress. The very low engine emissions are well below the strict EU limits, no exhaust gas aftertreatment is required.
Due to the different combustion behaviour of hydrogen compared to natural gas, some engine components including fuel injection, turbocharging, piston design and control, were modified in the test engine. However, by using proven technologies within the Power Systems’ portfolio, such as mtu turbochargers, injection valves, and engine electronics and control, the development of the engine to use hydrogen was advanced quickly and efficiently.
Diesel and natural gas internal combustion engine manufacturers like Cummins, Rolls-Royce mtu and several other companies, have a long history of research, that they have the knowledge to convert diesel or natural gas engines to hydrogen.
So far only Cummins, JCB and Rolls-Royce mtu have disclosed a multi-fuel line of engines.
First Deployment For CO2-Neutral Power Supply At Duisport
There is a section in the press release called First Deployment For CO2-Neutral Power Supply At Duisport, where this is said.
Duisport, one of the world’s largest inland ports, is working with several partners to build a hydrogen-based supply network for its new terminal, ready for operation in 2024. In the future, most of the electricity required by the port itself will be generated directly on site from hydrogen in a CO2-neutral manner. This will be achieved by two combined heat and power plants with mtu Series 4000 hydrogen engines (with a total installed capacity of 2MW) as well as three mtu fuel cell systems (with a total installed capacity 1.5MW).
As part of its sustainability program, Rolls-Royce is realigning the product portfolio of Power Systems towards more sustainable fuels and new technologies that can further reduce greenhouse gas emissions.
There is also this Rolls-Royce graphic, which shows the energy sources.
It would appear batteries, combined heap and power (CHP), grid electricity, hydrogen electrolyser, hydrogen storage and renewable electricity are being brought together to create a climate-neutral energy system.
Is this a world-first, where hydrogen engines and fuel cell systems will be working together?
Gondan Shipyard Launches Another Hydrogen-Ready CSOV
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Gondan Shipyard has launched another commissioning service operation vessel (CSOV) it is building for the Norwegian shipowner Edda Wind at its yard in Figueras, Spain.
Increasingly smaller ships are being built hydrogen-ready, so they can be converted to zero-carbon, when the technology is developed.
Over the last couple of years companies like Cummins, JCB and Rolls-Royce mtu have developed diesel engines that can be converted to hydrogen engines.
Cummins talk of agnostic engines, which are identical from the cylinder head gasket down and what is above it, can make the engine, diesel, hydrogen on natural gas powered.
‘Castle’ HSTs To Be Withdrawn By Great Western Railway
The title of this post, is the same as that of this article on Rail Advent.
This quote from a GWR spokesman, sums up the action that will be taken.
The Castles were always designed to be a temporary measure on the Cardiff to Penzance route. We expect to replace the Castle Class trains on a phased basis over the next couple of years, bringing customers the benefit of more modern trains that will reduce both cost and carbon emissions across the route.
These are my thoughts.
Could The Engines In The Power Cars Be Replaced With Modern Carbon-Neutral Engines?
This would be an alternative way to solve the decarbonisation problem.
It would also mean that other applications of the Class 43 power cars, like ScotRail’s Inter7City trains, Cross Country’s HSTs and Network Rail’s New Measurement Train would have a decarbonisation route,
In Rolls-Royce Releases mtu Rail Engines For Sustainable Fuels, Rolls-Royce mtu outline their route to decarbonise rail engines using sustainable fuels.
This was the first paragraph of my conclusion in the linked article.
Rolls-Royce and Cummins seem to be doing a thoroughly professional job in decarbonising the diesel engines they have made in recent years.
The Class 43 power cars have Rolls-Royce mtu Series 4000 engines, which will soon be available to run on sustainable fuel.
I think as a possible fall-back, one Class 43 power car should be converted to carbon neutral.
Could The Engines In The Power Cars Be Replaced With Modern Hydrogen Engines?
I looked at this in Will We See Class 43 Power Cars Converted To Hydrogen?.
I came to the conclusion, that this might be possible and said this.
It would be the ultimate Roller.
But then Rolls-Royce know about winning battles with large internal combustion engines.
The Option Of New Trains
This quote from a GWR spokesman was fairly definite about new trains, when they said.
The Castles were always designed to be a temporary measure on the Cardiff to Penzance route. We expect to replace the Castle Class trains on a phased basis over the next couple of years, bringing customers the benefit of more modern trains that will reduce both cost and carbon emissions across the route.
What trains could replace the Castles?
- The Cardiff and Penzance route is just short of 250 miles or roughly 400 kilometres.
- Only about 30 miles at the Cardiff end is electrified.
- Trains would need to be able to handle 25 KVAC overhead electrification.
- 125 mph trains will be needed at the Cardiff end.
- Four or five passenger cars will be needed.
- Currently, there are twelve Castles, so I will assume twelve new trains.
As these trains will be lasting up to forty years, they must be zero-carbon, which must mean battery-electric or hydrogen.
Charging Battery-Electric Trains
Consider
- Bristol Temple Meads, Exeter St. Davis and Plymouth are large stations with several platforms. I suspect that a number of Furrer + Frey’s charging stations can be installed along the route.
- The timetable would be adjusted to allow trains to be charged as they stopped to set down and pick up passengers.
- Trains would dwell in the station and then use their 125 mph performance to regain the time.
- I’ve also found a Penzance to Cardiff service, that stopped at Plymouth for fourteen minutes, which is more than enough to charge the batteries.
- Regenerative braking to the batteries would further eke out the range.
- There might also be some extra electrification around Bristol or Exeter.
- Some form of charging would be needed at Penzance.
Note.
- Putting up electrification may mean that it will delay the new trains for a few years.
- Charging stations along the route could probably be installed to a tight timetable.
I believe that with some top-class work, by battery and charger manufacturers, that a battery-electric train could be developed that could run between Cardiff and Penzance.
Thoughts On Hydrogen
Consider.
- The Alstom Coradia iLint train has a range of about 1,000 km. on hydrogen.
- Companies like Airbus, Boeing and a host of rocket makers will improve the storage and safety of hydrogen.
- A range of a 1,000 km. would allow refuelling at one end of the route.
- Trains could be multiple units or a hydrogen-electric locomotive pulling a rake of coaches with a driving van trailer.
I feel that hydrogen would be very feasible as a power source.
Alstom Could Offer A Hydrogen Aventra
Consider.
- Alstom are developing a hydrogen-powered Aventra.
- Bombardier were offering a 125 mph Aventra.
- A typical Aventra like a Class 720 train seats a hundred passengers a car.
A hydrogen Aventra would be feasible.
Hitachi Could Offer A Battery-Electric Or Hybrid AT-300
In 2021, in Hitachi And Eversholt Rail To Develop GWR Intercity Battery Hybrid Train – Offering Fuel Savings Of More Than 20%, I wrote about the announcement of the Hitachi Intercity Tri-Mode Battery Hybrid Train, which is shown in this Hitachi infographic.
Note.
- Batteries replacing an engine to cut fuel usage and reduce carbon emissions.
- First time a modern UK intercity train, in passenger service, will use alternative fuel.
- These Hitachi trains use mtu engines, so I suspect they will be switched to sustainable fuel like HVO.
- The trains are 125 mph and 140 mph with the latest digital signalling.
- Great Western Railway already have 58 five-car Class 800/802 trains and 35 nine-car 800/802 trains.
- They would not need any changing stations or other infrastructure changes.
- Staff retraining would be minimal.
Testing of the prototype of these trains must be getting very close or even underway.
Stadler Could Offer A Battery-Electric Flirt Akku
Consider
- Stadler have run a Flirt Akku on batteries for 243 km.
- Flirt Akkus will go into service soon.
- Flirts have been designed for 125 mph running.
With charging at Cardiff, Bristol, Exeter, Plymouth and Penzance, I believe a Flirt Akku could handle the route.
Are Hitachi Home And Hosed?
I have a feeling that the announcement has been made about retiring the Castles as the prototype Hitachi Intercity Tri-Mode Battery Hybrid Train is under test and is performing well.
So I wouldn’t be surprised to see an order for twelve more Class 802 trains soon.
Research And Development Agreement Signed For Hydrogen Combustion Trains In US
The title of this post, is the same as that of this article on H2-View.
This is the opening paragraph.
Hydrogen combustion engine-powered trains are set to be at the centre of a collaborative research and development agreement between Argonne and Oak Ridge National Laboratories and Wabtec in a bid to decarbonise US rail.
The US is certainly calling up the heavy brigade in Argonne National Laboratory, Oak Ridge National Laboratories and Wabtec.
This appears to be the main objective.
It is hoped the team will be able to design train engines that will deliver the same power, range, and cost-effectiveness as current diesel technology.
The article states that there are 25,000 diesel locomotives in the United States, but because of exports to large parts of the world, including the UK, this research could clean up a lot more than just the United States.
The omens are good, in that both Cummins and Rolls-Royce mtu, who are two of the world’s big diesel engine manufacturers have successfully launched hydrogen combustion engines.
Rolls-Royce Releases mtu Rail Engines For Sustainable Fuels
The title of this post, is the same as that of this press release from Rolls-Royce.
The press release starts with these bullet points.
- mtu Series 1300, 1500 and 1800 engines already released; Series 1600 and 4000 to follow shortly
- Up to 90% CO2 savings by operating existing engines with Hydrotreated Vegetable Oil (HVO/renewable diesel)
- Locally emission-free operation possible in combination with mtu Hybrid PowerPack
- Field tests with DB Cargo and RDC Autozug Sylt
Note.
- Hitachi Class 800, 802, 805 and Class 810 trains appear to use Series 1600 engines.
- CAF Class 195, 196 and Class 197 trains appear to use Series 1800 engines.
- Class 43 power cars, as used in InterCity 125 trains appear to use Series 4000 engines.
It would appear that many of the UK’s new diesel trains and the remaining Class 43 power-cars can be converted to run on HVO.
This paragraph from the press release gives more details.
Rolls-Royce is taking a significant step towards even more climate-friendly rail transport with the release of mtu rail engines for use with sustainable fuels. With synthetic diesel fuels of the EN15940 standard, CO2 emissions can be reduced by up to 100 percent compared to fossil diesel. Hydrotreated Vegetable Oil (HVO or renewable diesel), which is already commercially available today, reduces CO2 emissions by up to 90 percent. If the fuels are produced with the help of renewable energy and green hydrogen – through what is termed a Power-to-X process – existing rail vehicles can be operated in a completely CO2-neutral manner. The mtu Series 1800 engines which are used in mtu PowerPacks, as well as Series 1300 and 1500 for locomotives and multi-purpose vehicles, are already approved for use with synthetic fuels such as HVO. Series 1600 and versions of Series 4000 engines will follow in the near future. The release of engines for climate-friendly fuels requires a series of tests and trials and Rolls-Royce has found strong partners for this activity. DB Cargo and RDC Autozug Sylt have already tested or are currently testing mtu Series 4000 engines with HVO in their locomotives.
Rolls-Royce mtu seem to have covered all issues.
This is a very significant statement in the paragraph.
If the fuels are produced with the help of renewable energy and green hydrogen – through what is termed a Power-to-X process – existing rail vehicles can be operated in a completely CO2-neutral manner.
This must be the most affordable way to make your diesel trains zero carbon.
Conclusion
Rolls-Royce and Cummins seem to be doing a thoroughly professional job in decarbonising the diesel engines they have made in recent years.
It now needs someone to take small diesel engines down the conversion route, just as Rolls-Royce mtu and Cummins are cleaning up their large engines.
