A Brief Glimpse Of The Class 799 Train On BBC Breakfast
The Class 799 train is being launched today and BBC Breakfast were there with cameras.
These are my thoughts.
A Test Train
Helen Simpson from Porterbrook, said it was very much a test train.
Seats appear to be in some of the cars.
It looks like Birmingham University have sensibly put the hydrogen drive system in one or both of the two central cars, which in the original Class 319 train were given the designations PMSO and MSOL
The Hydrogen Tanks And Fuel Cell
The hydrogen tanks didn’t appear to be unduly large, which suggests, the the train is not going for a very long rang. But it is only a test train.
The fuel cell was clearly marked from Ballard and was just a large anonymous box. I would think, that it was probably upwards of 100 kW.
It should be noted that the Class 319 train was originally a 1,000 kW train, with a top speed of 100 mph and good acceleration.
I’ll be interested to see what size these components are, when they are published.
The Battery System
The battery did appear to be large, but then these are probably not batteries designed to fit the train, but what is available.
As with the hydrogen tanks and fuel cell, sizes would appear to have been chosen large enough to make sure that the train is not significantly less powerful, than current Class 319 trains.
JR East To Test Hydrogen Fuel Cell Trains
The title of this post is the same as that of this article on Japan Times.
This is the first paragraph.
East Japan Railway Co., or JR East, has announced a plan to test new electric-powered trains using hydrogen fuel cells from fiscal 2021.
It does seem that hydrogen power is being increasingly considered.
Chester To Liverpool Via Runcorn
This new service between Chester and Liverpool Lime Street stations via Runcorn station and the Halton Curve, started a couple of weeks ago.
I took these pictures of the journey.
Note.
- The service was busy, as everybody seemed to be going to Liverpool to prepare for the evening’s match.
- The Class 150 train kept up a good speed, which indicates that Network Rail didn’t cut quality on the link.
- Runcorn is about the halfway point of the journey.
- The route is electrified between Runcorn and Liverpool Lime Street stations.
- The Class 150 train was a bit tired.
I wouldn’t be surprised to see a hybrid train working this route.
- Transport for Wales have ordered some electro-diesel Class 769 trains.
- Alstom are converting Class 321 trains into hydrogen-powered Class 321 Breeze trains at nearby Widnes.
- Porterbrook are converting Class 350 trains into Battery/FLEX trains.
- Hitachi are talking to ScotRail about Class 385 trains with batteries.
- I’m also sure Bombardier have a battery-electric Aventra.
Operation would be as follows.
- All these trains work be capable of 100 mph using 25 KVAC overhead electrification between Liverpool Lime Street and Runcorn stations.
- Power changeover would be at Runcorn station.
- Between Runcorn to Chester stations is only about fourteen miles.. This will be well within battery range in a few years.
Transport for Wales will be obtaining trains from a crowded market.
More Halton Curve Services
Under Planned Improvements in the Wikipedia entry for Transport for Wales, this is said.
Introduction of a new hourly Liverpool to Llandudno and Shrewsbury service, and a new two-hourly Liverpool to Cardiff Central service from December 2022.
Adding these to the current hourly service, this would mean that two trains per hour (tph) would normally run between Liverpool Lime Street and Chester stations, with three trains in every alternate hour.
I think that, there would be a marketing advantage in running hybrid trains on these routes. Hydrogen would be ideal, as these would not need recharging like battery trains after a long trip.
To go through the single-track Halton Curve appears to take trains about five minutes, so up to eight tph could probably be feasible, which would mean four tph between Liverpool and Chester via Runcorn in both directions.
If Trains for Wales are going to compete with the Merseyrail electric services, they need a four tph frequency in both directions.
Flexible Ticketing
Currently, if you want to buy a ticket between the Chester and Liverpool Lime Street, you have to buy an appropriate ticket for your chosen route.
Surely, tourists and others might like to do the out and back journeys by a different route.
If London Underground and some train companies can share ticketing, then surely Merseyrail and other train companies can do the same.
Conclusion
This new service will be surprisingly well-used and needs an iconic hybrid train.
- Diesel is not appropriate for the long term, although in Northern Connect Between Chester And Leeds To Start In May, I did report a rumour that Class 769 trains might be running between Chester and Leeds.
- Hydrogen is non-polluting and has a longer range, that could make services between Liverpool and Holyhead possible.
- Battery will probably need a charging infrastructure.
My money is on hydrogen power.
Breeze Hydrogen Multiple-Unit Order Expected Soon
The title of this post is the same as that of this article on Railway Gazette.
This is the first paragraph.
Alstom Transport is hopeful of confirming an order before the end of this year for its Breeze hydrogen multiple-unit trains being developed in partnership with leasing company Eversholt Rail, suggesting that the first trains could enter service ‘as early as 2022’.
It then goes out to fill out some of the thinking behind the Alstom Breeze hydrogen-powered train.
The Breeze Is A Stop-Gap
Alstom are quoted as indicating the Breeze is an interim solution, until the next generation of train is available.
But after a ride to Southend recently in a Class 321 Renatus, I’m sure that the ride and passenger acceptance will be of a high standard.
And that’s what counts. Hydrogen is only the train’s personal power supply.
Alstom Are Not Building A Suburban Trundler
The Alstom Coradia iLint is not an exciting train.
- It has a cruising speed of 87 mph.
- It has a range of 370-500 miles.
- It has a noisy mechanical transmission.
- It always runs on hydrogen-power.
- The prototypes have covered 100,000 km.
In my view, it is very much a first generation compromise design.
The article says more about the Alstom Breeze.
- It has a slightly faster cruising speed of 90 mph
- The Breeze will have 50% more power than the iLint. Does this mean better acceleration and/or a longer and heavier train?
- It will have a 1,000 km range.
- It will have regenerative braking to the train’s batteries.
- It will have a new AC traction package, as does a Class 321 Renatus. So will the two systems be the same? Or at least similar?
I am also fairly sure, the train will be able to use electrification of both 25 KVAC overhead and 750 VDC third-rail, as Class 321 trains can now!
Train Capacity
This is said about train capacity.
Despite the loss of some seating space, each set of three 20 m vehicles would provide slightly more capacity than a two-car DMU with 23 m cars which it would typically replace.
The Class 172/0 trains, that are two-car 23 metre diesel multiple units, have 124 seats.
In Hydrogen Trains Ready To Steam Ahead, I estimated that a three-car Alstom Breeze would have a seating capacity of around 140 seats, with the ability to perhaps take an additional 160 standees.
So was my seat estimate fairly good? I also think, that as the Breeze has been designed with bags of grunt, I suspect that the basic train could be increased in size by adding extra trailer cars.
After all, the legendary Class 442 train is a five-car train, with a power-car in the middle. South Western Railway, think they are worth pulling out of the scrapyard and refurbishing to run expresses between Waterloo and Portsmouth.
I am fairly certain, that Alstom can create a five-car Class 321 Breeze with the following characteristics.
- A capacity of about three hundred seats
- A smaller three-car train would have 140 seats.
- A near-100 mph top speed on hydrogen-power.
- A 100 mph top speed on electrification.
- A 1000 km range on hydrogen.
- Regenerative braking to an on-board battery.
- The ability to use 25 KVAC overhead and/or 750 VDC third rail electrification.
The trains could have the ability to run as pairs to increase capacity.
The train would be ideal for the following routes.
- Liverpool and North Wales via Chester
- Norwich and Derby
- Newcastle and Carlisle
- Preston and Carlisle via Barrow
- Cardiff and the South Coast of England
- Borders Railway
- Southampton and Ashford
- Waterloo and Exeter
All of these routes have partial electrification, which would reduce the amount of hydrogen needed to be carried around.
Now that is an interesting multi-variable calculation!
Hydrogen Infrastructure
Alstom seem to be developing infrastructure solutions to supply hydrogen for fleets of ten or more trains, which could be shared with other applications. The obvious one could be where a train depot and a fleet of buses share a facility in say a large city like Exeter, which has an extensive diesel train network.
The article also says this about the source of hydrogen.
Ideally, the trains would use ‘green’ hydrogen manufactured by electrolysis using surplus renewable energy rather than ‘brown’ hydrogen from steam methane reforming.
I agree wholeheartedly with that!
Delivery In 2022?
Consider what has already been achieved in other projects.
- Alstom have proved they can generate enough electricity to power a practical train.
- Eversholt have proved that you can turn Class 321 trains into comfortable and efficient 100 mph Class 321 Renatus trains for routes up to a hundred miles.
- Several classes of Mark 3-based electrical multiple units have been re-engined with AC traction, including the Class 321 Renatus.
- Engineers all over the UK have modified Mark 3-based coaches and multiple units to create better and more-efficient trains.
Helping delivery of the project, is a legacy of drawings and philosophy from British Rail Engineering.
If Alstom say 2022, I believe that that could be a feasible date.
Conclusion
The ghost of British Rail Engineering is certainly a benign one allowing all sorts of worthwhile development paths.
Vivarail And Arcola Announce Partnership To Bring Emission-Free Trains To The UK
The title of this post is the same as this press release from Vivarail.
These are the first two paragraphs
Vivarail, designers and manufacturers of the Class 230 trains, and hydrogen fuel cell specialists Arcola Energy today announced a long-term collaboration.
The companies share a determination to help de-carbonise the UK’s transport system. Vivarail has already designed and run an emission-free battery train whilst Arcola lead the market in supplying power systems for efficient fuel cell electric vehicles, primarily buses, to the UK. Working together the companies will develop a hydrogen/battery hybrid train.
It strikes me that this could be a good fit.
Powering A Bus
In New Facility To Power Liverpool’s Buses With Hydrogen, I described Arcola Energy’s involvement in a project to create and fuel hydrogen-powered buses in conjunction with Alexander Dennis.
- A typical hybrid double-decker bus like a New Routemaster has a battery capacity of 55 kWh.
- If these Liverpool hydrogen-powered double-decker buses have serial hybrid transmission like the New Routemaster, I could envisage them having a battery of up to 100 kWh, as let’s face it, the New Routemaster design is now eight years old and battery technology has moved on.
So the Arcola Energy-sourced fuel cell must be able to continuously top-up, the battery, in the same manner as the diesel engine on a hybrid bus.
Sit in the back of a New Routemaster and you can hear the engine cutting in and out. It doesn’t seem to work very hard, even on routes like the 73, which operate at high loadings.
Powering A Class 230 Train
Vivarail’s battery-powered Class 230 train, has a battery capacity of 106 kWh.
This size of battery could certainly be changed by a hydrogen fuel cell.
But could a hydrogen fuel cell provide enough power to keep the train running?
- Vivarail are clamming a range of fifty miles, which means that their two-car battery trains are consuming around 2 kWh for every mile.
- I will assume the train is travelling at its operating speed of sixty mph, which is a mile every minute.
- To keep the battery topped up would need 2 kWh to be produced every minute.
A hydrogen fuel cell with a rating of 120 kW would be needed to power the train continuously. But as the fuel cell would only be topping up the battery, I suspect that a smaller fuel cell would be sufficient.
The Ballard fuel cell is a HD variant of their FCveloCity family.
This page on the Ballard web site is the data sheet of an HD fuel cell of their FCveloCity family.
- The fuel cells come in three sizes 60, 85 and 100 kW
- The largest fuel cell would appear to be around 1.2 m x 1 m x 0.5 m and weigh around 400 Kg.
- The fuel cell has an associated cooling subsystem, that can provide heat for the train.
This Ballard fuel cell would appear to be capable of mounting under the floor of a train.
There are probably several other fuel cells that will fit the Class 230 train.
Arcola should know the best hydrogen fuel cell for the application, in terms of size, power and cost.
The Concept Train
Vivarail’s press release describes a concept train.
The concept train will be used to demonstrate the system capability and test performance. Vivarail’s production hydrogen trains will consist of 4-cars, with 2 battery driving motor cars and 2 intermediate cars housing the fuel cell and tanks.
Vivarail seem very certain of the formation of production trains.
I am not surprised at this certaincy.
- The mathematics of battery-powered and hydrogen-powered trains is well known.
- Vivarail have experience of running their battery-powered prototype.
- Arcola have experience of the capabilities of hydrogen-power.
I also wouldn’t be surprised to see some commonality between the Alexander Dennis and Vivarail installations.
Range Of A Hydrogen-Powered Class 230 Train
Nothing is said in Vivarail’s press release about the range on hydrogen.
In Hydrogen Trains Ready To Steam Ahead, I examined Alstom’s Class 321 Breeze hydrogen train, based on an article in The Times.
I said this about range.
The Times gives the range of the train as in excess of 625 miles
The Class 321 Breeze looks to be designed for longer routes than the Class 230 train.
I would suspect that a hydrogen-powered Class 230 train would have the range to do a typical day’s work without refuelling.
Refuelling A Hydrogen-Powered Class 230 Train
I don’t think this will be a problem as Arcola appear to have the expertise to provide a complete solution.
Conclusion
This is a co-operation, where both parties are bringing strengths to the venture.
Alstom Coradia iLint Hydrogen-Powered Train Video
I’ve just found this video from Alstom.
Intriguingly, the video was filmed at Braunschweig Hauptbahnhof, which is in another part of Germany, about two hundred kilometres to the South-East of Hamburg.
There does seem to be several local services radiating from the City on lines without electrification.
Hydrogen Trains To Be Trialled On The Midland Main Line
This article on Railway Gazette is entitled Bimode And Hydrogen Trains As Abellio Wins Next East Midlands Franchise.
Abellio will be taking over the franchise in August this year and although bi-mode trains were certain to be introduced in a couple of years, the trialling of hydrogen-powered trains is a surprise to me and possibly others.
This is all that is said in the article.
Abellio will also trial hydrogen fuel cell trains on the Midland Main Line.
It also says, that the new fleet will not be announced until the orders are finalised.
In this post, I’m assuming that the hydrogen trial will be performed using the main line trains.
Trains for the Midland Main Line will need to have the following properties
- 125 mph on electric power
- 125 mph on diesel power
- Ability to go at up to 140 mph, when idigital n-cab signalling is installed and the track is improved.
- UK gauge
- Ability to run on hydrogen at a future date.
I think there could be three types of train.
- A traditional bi-mode multiple unit, with underfloor engines like the Hitachi Class 800 series, is obviously a possibility.
- An electrical multiple unit, where one driving car is replaced by a bi-mode locomotive with appropriate power.
- Stadler or another manufacturer might opt for a train with a power pack in the middle.
The second option would effectively be a modern InterCity 225.
- South of Kettering, electricity would be used.
- North of Kettering, diesel would be used
- Hydrogen power could replace diesel power at some future date.
- Design could probably make the two cabs and their driving desks identical.
- The locomotive would be interchangeable with a driver car.
Bi-modes would work most services, with electric versions working to Corby at 125 mph.
Which manufacturer has a design for a 125 mph, hydrogen-powered train?
Alstom
Alstom have no 125 mph UK multiple unit and their Class 321 Hydogen train, is certainly not a 125 mph train and probably will still be under development.
Bombardier
In Mathematics Of A Bi-Mode Aventra With Batteries, I compared diesel and hydrogen-power on bi-mode Aventras and felt that hydrogen could be feasible.
In that post, I wrote a section called Diesel Or Hydrogen Power?, where I said this.
Could the better ambience be, because the train doesn’t use noisy and polluting diesel power, but clean hydrogen?
It’s a possibility, especially as Bombardier are Canadian, as are Ballard, who produce hydrogen fuel-cells with output between 100-200 kW.
Ballard’s fuel cells power some of London’s hydrogen buses.
The New Routemaster hybrid bus is powered by a 138 kW Cummins ISBe diesel engine and uses a 75 kWh lithium-ion battery, with the bus being driven by an electric motor.
If you sit in the back of one of these buses, you can sometimes hear the engine stop and start.
In the following calculations, I’m going to assume that the bi-mode |Aventra with batteries has a power source, that can provide up to 200 kW, in a fully-controlled manner
Ballard can do this power output with hydrogen and I’m sure that to do it with a diesel engine and alternator is not the most difficult problem in the world.
So are Bombardier designing the Bi-Mode Aventra With Batteries, so that at a later date it can be changed from diesel to hydrogen power?
All an Aventra needs to run is electricity and the train, the onboard staff and passengers don’t care whether it comes from overhead wires, third-rail, batteries, diesel or hydrogen.
Bombardier also have the technology for my proposed locomotive-based solution, where one driver-car of an Aventra is replaced by what is effectively a locomotive.
If Bombardier have a problem, it is that they have no small diesel train to replace Abellio’s small diesel trains. Could the longer services use the bi-mode Aventras and the shorter ones Aventras with battery power?
CAF
CAF probably have the technology, but there would be a lot of development work to do.
Hitachi
Hitachi have the bi-mode trains in the Class 802 trains, but haven’t as yet disclosed a hydrogen train.
Siemens
They’ve made a few noises, but I can’t see them producing a bi-mode train for 2022.
Stadler
In a few weeks time, I will be having a ride in a Stadler-built Class 755 train, run by Abellio Greater Anglia.
The Class 755 train is a bi-mode 100 mph train, from Stadler’s Flirt family.
Could it be stretched to a 125 mph train?
- Stadler have built 125 mph electric Flirts.
- It is my view, that Stadler have the knowledge to make 125 mph trains work.
- Flirts are available in any reasonable length.
- I’ve read that bi-mode and electric Flirts are very similar for drivers and operators.
These could work the Midland Main Line.
If the mainline version is possible, then Abellio could replace all their smaller diesel trains with appropriate Class 755 trains, just as they will be doing in East Anglia.
Stadler with the launch of the Class 93 locomotive, certainly have the technology for a locomotive-based solution.
East Midlands Railway would be an all-Stadler Flirt fleet.
As to hydrogen, Stadler are supplying hydrogen-powered trains for the Zillertalbahn, as I wrote in Zillertalbahn Orders Stadler Hydrogen-Powered Trains.
Talgo
Talgo could be the joker in the pack. They have the technology to build 125 mph bi-mode trains and are building a factory in Scotland.
My Selection
I think it comes down to a straight choice between Bombardier and Stadler.
It should also be noted, that Abellio has bought large fleets from both manufacturers for their franchises in the UK.
Zero-Carbon Pilots At Six Stations
This promise is stated in the franchise.
Once the electrification reaches Market Harborough in a couple of years, with new bi-mode trains, running on electricity, the following stations will not see any passenger trains, running their diesel engines.
- St. Pancras
- Luton Airport Parkway
- Luton
- Bedford
- Wellingborough
- Kettering
- Corby
- Market Harborough
These are not pilots, as they have been planned to happen, since the go-ahead for the wires to Market Harborough.
Other main line stations include.
- Beeston
- Chesterfield
- Derby
- East Midlands Parkway
- Leicester
- Long Eaaton
- Loughborough
- Nottingham
- Sheffield
Could these stations be ones, where East Midlands Railway will not be emitting any CO2?
For a bi-mode train to be compliant, it must be able to pass through the station using battery power alone.
- As the train decelerates, it charges the onboard batteries, using regernerative braking.
- Battery power is used whilst the train is in the station.
- Battery power is used to take the train out of the station.
Diesel power would only be used well outside of stations.
How would the trains for the secondary routes be emission-friendly?
- For the long Norwich to Derby and Nottingham to Liverpool routes, these would surely be run by shorter versions of the main line trains.
- For Stadler, if secondary routes were to be run using Class 755 trains, the battery option would be added, so that there was no need to run the diesel engines in stations.
- For Bombardier, they may offer battery Aventras or shortened bi-modes for the secondary routes, which could also be emission-free in stations.
- There is also the joker of Porterbrook’s battery-enhaced Class 350 train or BatteryFLEX.
I think that with the right rolling-stock, East Midlands Railway, could be able to avoid running diesel engines in all the stations, where they call.
Why Are Abellio Running A Hydrogen Trial?
This is a question that some might will ask, so I’m adding a few reasons.
A Train Manufacturer Wants To Test A Planned Hydrogen Train
I think that it could be likely, that a train manufacturer wants to trial a hydrogen-powered variant of a high-speed train.
Consider.
- The Midland Main Line is about 160 miles long.
- A lot of the route is quadruple-track.
- It is a 125 mph railway for a proportion of the route.
- It has only a few stops.
- It is reasonably straight with gentle curves.
- Part of the route is electrified.
- It is connected to London at one end.
In my view the Midland Main Line is an ideal test track for bi-mode high speed trains.
A Train Manufacturer Wants To Sell A Fleet Of High Speed Trains
If a train manufacturer said to Abellio, that the fleet of diesel bi-mode trains they are buying could be updated to zero-carbon hydrogen bi-modes in a few years, this could clinch the sale.
Helping with a trial, as Abellio did at Manningtree with Bombardier’s battery Class 379 train in 2015, is probably mutually-beneficial.
The Midland Main Line Will Never Be Fully Electrified
I believe that the Midland Main Line will never be fully-electrified.
- The line North of Derby runs through the Derwent Valley Mills World Heritage Site. Would UNESCO allow electrification?
- I have been told by drivers, that immediately South of Leicester station, there is a section, that would be very difficult to electrify.
- Some secondary routes like Corby to Leicester via Oakham might be left without electrification.
But on the other hand some sections will almost certainly be electrified.
- Around Toton, where High Speed Two crosses the Midland Main Line and the two routes will share East Midlands Hub station.
- Between Clay Cross North Junction and Sheffield, where the route will be shared with the Sheffield Spur of High Speed Two.
- The Erewash Valley Line, if High Speed Two trains use that route to Sheffield.
The Midland Main Line will continue to need bi-mode trains and in 2040, when the Government has said, that diesel will not be used on UK railways,
It is my view, that to run after 2040, there are only two current methods of zero-carbon propulsion; on the sections without overhead electrification battery or hydrogen power.
So we should run trials for both!
Abellio Know About Hydrogen
Abellio is Dutch and after my trip to the Netherlands last week, I wrote The Dutch Plan For Hydrogen, which describes how the Dutch are developing a green hydrogen economy, where the hydrogen is produced by electricity generated from wind power.
So by helping with the trial of hydrogen bi-mode trains on the Midland Main Line, are Abellio increasing their knowledge of the strengths and weaknesses of hydrogen-powered trains.
In Thoughts On Eurostar To North Netherlands And North West Germany, I proposed running bi-mode trains on the partially-electrified route between Amsterdam and Hamburg via Groningen and Bremen, which would be timed to connect to Eurostar’s services between London and Amsterdam. These could use diesel, hydrogen or battery power on the sections without electrification.
If hydrogen or battery power were to be used on the European bi-mode train, It would be possible to go between Sheffield and Hamburg on a zero-carbon basis, if all electric power to the route were to be provided from renewable sources.
Abellio Sees The PR Value In Running Zero-Carbon Trains
In My First Ride In An Alstom Coradia iLint, I talked about running hydrogen-powered trains on a hundred mile lines at 60 mph over the flat German countrside
The Midland Main Line is a real high speed railway, where trains go at up to 125 mph between two major cities, that are one-hundred-and-sixty miles apart.
Powered by hydrogen, this could be one of the world’s great railway journeys.
If hydrogen-power is successful, Abellio’s bottom line would benefit.
Conclusion
This franchise will be a big improvement in terms of carbon emissions.
As I said the choice of trains probably lies between Bombardier and Stadler.
But be prepared for a surprise.
The Dutch Plan For Hydrogen
The Dutch Plan For Hydrogen
I have cut this out of The Train Station At The Northern End Of The Netherlands, so don’t read if if you’ve read it before.
Searching Google for hydrogen around Groningen, I found this document on the Internet, which is entitled Green Hydrogen Economy In The Northern Netherlands.
It is a fascinating read about what you can do with hydrogen generated from wind and biomass.
This is a sentence from the document.
Large scale green hydrogen product.ion together with harbor transport and storage facilities will be located at Eemshaven, with green chemicals production in Delfzijl
It is an ambitious statement.
Eemshaven
It also appears that Eemshaven will be the main connection point for electricity from offshore wind farms. This is said.
In the Eemshaven an offshore electricity cable from Norway, the NorNed cable with a capacity of 700 MW, comes on land. The Cobra cable, with a capacity of 700 MW, from Denmark is foreseen to connect at the Eemshaven to the onshore grid. The Gemini wind farm is connected to the grid in the Eemshaven with a capacity of 600 MW. Within 10 years it is foreseen that another 4.000 MW offshore wind will have their electricity cable to the Eemshaven.
Does all this explain, the building of a station at Eemshaven? Delfzijl station was built in 1883 and has its own connection to Groningen.
The following proposed actions are from the document
Build A 1,000 MW Electrolysis Plant
This is an extract from the of the document.
A 1.000 MW electrolysis plant that runs 8.000 hours a year, uses 8 billion kWh and 1,5 million m3 pure water to produce 160 million kg Hydrogen. A reverse osmosis plant has to produce the 1.5 million m3 pure water, using sea water or surface water as input. If an electricity price of 2‐2,5 €ct/kWh and a total investment between 500 million and 1 billion Euro with a 10 year life time is assumed, a green hydrogen cost price around 2‐3 €/kg will be the result. This is about competitive with present hydrogen prices, produced from natural gas by steam reforming.
How much energy is contained in a Kg of hydrogen?
This page on IdealHY says the following.
Hydrogen is an excellent energy carrier with respect to weight. 1 kg of hydrogen contains 33.33 kWh of usable energy, whereas petrol and diesel only hold about 12 kWh/kg.
At three euros for a kilogram of hydrogen, that works out at nine euro cents for a kWh.
Build A 1000 MW Biomass Gasification Plant
The title is a section in the document and this is an extract from the section.
Green hydrogen can be produced by electrolysis using green electricity, but can be produced also from biomass via gasification. Biomass gasifiers use solid biomass as an input and deliver a green syngas, a mixture of hydrogen, carbon‐monoxide (CO) and carbon‐dioxide (CO2), and char as an output. The CO could be used, together with water (H2O), to produce extra hydrogen. The resulting products from biomass gasification are green hydrogen and CO2. However, from CO2 and green hydrogen every chemical product could be produced. Therefore, the combination of green hydrogen and CO2 or green syngas creates the opportunity for a fully green chemical industry in the Northern Netherlands.
The process is still being developed. My first question, is can you use animal manure as a feedstock? It should be noted that The Netherlands used to have a very large and smelly manure problem.
Offshore Hydrogen Production From Far Offshore Wind Farms
The title is a section in the document and this is an extract from the section.
Offshore wind farms produce electricity which can be brought onshore via an electricity cable. Such an offshore electricity cable is expensive. The farther offshore the wind farm is located the more expensive the electricity cable cost. At the North Sea, an alternative solution for these wind farms is to convert the electricity into hydrogen at an existing oil/gas platform and to transport this hydrogen eventually mixed with gas via an existing gas pipeline. Onshore the hydrogen is separated from the natural gas and cleaned to be transported via pipeline, ship or truck to the markets.
I think that the technology and existing infrastructure could be made to work successfully.
- Europe has over fifty years experience of handling offshore gas networks.
- Recent developments have seen the emergence of floating wind turbines.
- Would it be easier to refurbish redundant gas platforms and use them to collect electricity and create hydrogen, rather than demolish them?
- Hydrogen is only produced when the wind blows.
- There is no need to store electricity and we’ve been storing gas since the Victorians.
There will be problems, like the integrity of an ageing pipeline, but I suspect that the expertise to solve them exists.
Will there be a North Sea, where every part has a large wind farm?
Note that the Hornsea Wind Farm has an area of 1830 square miles and could generate around 6 GW, when fully developed.You could fit 120 wind farms of this size into the North Sea. Even if only a small proportion could be developed, a sizeable amount of hydrogen could be produced.
A Market For 300,000‐tonnes Green Methanol + 300,000‐tonnes Green Ammonia
The title is a section in the document and this is an extract from the section.
Hydrogen (H2) and Carbon‐dioxide (CO2) can be used in chemical processes to produce a wide variety of chemical products. Two of the main building blocks in chemistry are methanol and ammonia. Methanol can be produced from H2 and CO2. Ammonia is produced from H2 and nitrogen (N2), captured from the air.
Wind power and biomass have been used tp create the basic chemicals for the petro-chemical industry.
The Construction Of Green Hydrogen Fuel Cell Balanced Data Centres
The title is a section in the document and this is an extract from the section.
Google builds a very large data center in the Eemshaven, see picture below. The reasons for Google to choose for the Eemshaven are the existence of an offshore data cable, enough space and green electricity. Google as well as other companies that install and operate data centers wants to run on green electricity. Therefore, Google has signed a power purchase agreement with Eneco to buy green electricity for 10 years. For this reason, Eneco builds an onshore wind farm nearby. On a yearly average this wind farm produces enough electricity to meet the data center demand.
However, supply and demand are not at every time in balance. At moments that there is no wind, other power plants must take over the electricity supply. Now, these are fossil fired power plants.In future, these power plants will be closed and supply and demand needs to be balanced in another way. And of course, that needs to be done with renewable electricity. This can be done by fuel cells fueled with green hydrogen. Fuel cells can follow demand and supply variations very fast with high efficiencies. Fuel cells are quiet and have no emissions, except very clean, demineralized, water.
I like this concept.
Surely, we could build a few data centres in places like Lincolnshire.
Build A Pipeline To Rotterdam And Germany
The Dutch have ambitious plans to export the hydrogen.

Hydrogen Trains In The Northern Netherlands
The document says this about trains powered by hydrogen fuel cells.
In the Northern Netherlands, 50 diesel trains are daily operated on non‐electric lines. These trains, operated by ARRIVA have two or three carriages and a power of 450‐600KW supplied by Diesel‐Electric engines. Fuel cell‐electric hydrogen trains could replace these diesel trains. Alstom is a company that builds these fuel cell hydrogen trains and will perform a test next year on the line Groningen‐Bremen. Because the depreciation time for trains is 25 years, not all trains will be bought new. Some trains may need to be retrofitted with fuel cell‐electric power supply, which is technically feasible. When all these 50 diesel trains are replaced an investment in new and retrofitted trains of about …? Million Euros is needed. The total hydrogen consumption of these trains is about 5,000 ton.
These points are shown in a table.
- Total (diesel) trains in the Northern Netherlands is 50 units
- Hydrogen consumption approximately 25 kg H2/100km
- Train operations average 6 days per week. Train is operated approximately 1.200 km per day, based on two times per hour per trajectory of 50km.
- Train operations average 6 days per week. 330 days per year.
- Capital expenditure per train approximately …. ? 50 Units …? Million Euro
- 50,000 tonnes of hydrogen will be needed.
- The fuel bill at three euros a Kg will be 150 million euro.
Would this be economic?
From various comments, I suspect that Stadler are working on a hydrogen-powered GTW.
But failing that, as Stadler are developing a diesel/electric/battery Flirt for the South Wales Metro and some of the routes from Groningen are only about 30 km, I wouldn’t be surprised to see diesel/electric/battery GTWs running across the flat lands of the North.
Battery trains could be fitted with pantographs and recharge in Groningen, where most of the platforms are electrified.
There are a lot of possibilities and engineers will come up with the best solution with regards to operation and economics.
Conclusion
Thr Dutch have big plans for a hydrogen-based economy in the North of the Netherlands.
Where is the UK Government’s master plan for hydrogen?
My First Ride In An Alstom Coradia iLint
I’m finally, riding in a hydrogen-powered Alstom Coradia iLint train through the German countryside.
Not as quiet as the two battery trains, I’ve ridden, but that’s because It feels to me that the traction motors are crudely under the passengers and cardan shafts are used to drive the wheels!
Battery electric trains with regenerative braking should be virtually free of any mechanical noise. Both the Class 379 and Class 230 battery demonstrators were almost silent. As electricity generated from hydrogen doesn’t appear to generate much noise, then a hydrogen-powered train can also be almost silent.
From talking to fellow passengers, it would appear that the train has been very reliable in service.
Alstom are proving hydrogen would work well in a train designed for that purpose, but updating a DMU with a mechanical transmission, possibly isn’t the way to go.
Class 321 Breeze Train
I think that the Class 321 Breeze train will be quieter and faster.
It appears too, that if Alstom’s conversion follows the design of the Class 321 Renatus, the train will have a totally flat floor.
Come to think of it, I can’t think of a train running in the UK, that doesn’t have a totally flat floor!
The iLint, like the Lint has several sets of steps.
These are not acceptable in a modern train, bus or tram.
Lint 41 And iLint Compared
It is interesting to compare the iLint with the current diesel Lint 41s on the route.
- The iLint is faster and may accelerate better.
- The iLint is based on the bigger Lint 54, so it has more seats and two doors instead of one on each side of the cars.
- The newer iLint appears to have a higher quality interior.
I feel that the iLint will be quicker on a real.route.
The Future Of Buxtehude And Cuxhaven
Currently, to go between Buxtehude and Cuxhaven and back to Buxtehude takes around five hours. So that means the current hourly service needs five trains.
But if the iLint could do a round trip in four hours, the number of trains would be teduced to four.
If to increase capacity, all trains were pairs of iLints, the number of trains required would be eight.
Supposing it was required to double frequency, this would mean sixteen trains would be needed!
And how many trains have been ordered? Sixteen!
Coincidence or good planning?
Publicising The Achievement
When Bombardier created the Class 379 IPEMU, they made certain that there was a lot of local publicity including a report on BBC Look East.
I made a point of asking local residents about the train and no-one had heard of it. Although, I must say that students who regularly used the train, were very much in favour.
This was the only information, I found about the train.
It was only in German, which I can read,. But surely, such an important achievement deserves better publicity and explanation in perhaps German, English and French.
Conclusion
Alstom have proved that hydrogen-power is possible in a smaller train, suitable for regional routes.
My reservations are totally about the Lint, which is an inferior train compared to many others that I’ve ridden in the UK and Europe.
I wouldn’t like to use the train in a wheel-chair!
The next generation of purpose-built trains with hydrogen power will be much better!
Is This Stadler’s Plan For A Multi-Mode Future?
We have not seen any of Stadler’s bi-mode Flirts in service yet although Greater Anglia’a Class 755 trains have been rumoured to be speeding between London and Norwich in ninety minutes from this May!
Today, I rode on one of Stadler’s diesel GTWs between Groningen and Eemshaven in the Netherlands, which I wrote about in The Train Station At The Northern End Of The Netherlands.
GTWs are a diesel electric train with a power-pack car in the middle of the three car train. The diesel electric Flirts are a later train with a similar layout to the GTW.
So are the diesel GTWs and Flirts just a bi-mode without a pantograph? Or more likely the bi-mode is a diesel electric train with the addition of a pantograph and extra electrical gubbins.
Looking at the visualisations on Wikipedia of the bi-mode Class 755 train and the all-electric Class 745 train, it appears that the next-to-end car has the pantograph.
Are these cars with the pantograph identical on both the bi-mode and the all-electric versions? It would certainly be sensible from a engine erring point of view.
So could it be that all that is needed to convert a diesel electric Flirt into a bi-mode Flirt is to add the pantograph car and swap the power pack car for a bi-mode one? The old power pack car could then be converted into another bi-mode power pack car to convert another train.
But the power pack cars are not as simple as they look. They have four slots for diesel engines. Three-car and four-car Class 755 trains have two and four engines respectively.
I believe that one or more of the slots can be filled with a battery to create Flirts like the tri-mode ones proposed for South Wales.
So could we see some of the Greater Anglia Flirts converted in this way? Surely, Colchester Town to Sudbury could be a service that could benefit from battery power West of Marks Tey?
Today, I had a chat with a GTW driver, who said that the train he’d been driving was diesel-electric and that he had heard that batteries or hydrogen power could be used on the eoute.
The lines around Groningen seem to employ quite a few GTWs and distances are not overly long. So could some be converted to 1500 VDC electric/diesel/battery tri-modes? There is electrification at Groningen station and some of the bay platforms used by GTWs already have wires.
If the conversion is successful, then Stadler could be on a Swiss roll, as there are a lot of GTWs and Flirts out there, many of which are diesel-electric, like the one I rode today.
Would a train operator prefer to upgrade a diesel electric train that works well or buy a new bi-mode from another train manufacturer?
Could also an electric Flirt be converted into a bi-mode, by splitting the train and sticking a power pack car in the middle. Engineering common sense says that the passenger cars must be very similar to those of diesel Flirts to simplify manufacture of the trains.
We already know, that four-car Flirts are only three-car trains with an extra passenger car. Stadler could mix-and-match passenger, pantograph and power pack cars to give operators what they need.
Intelligent computer software would choose which power option to be used and the driver would just monitor, that the train was behaving as needed.
Looking at my route yesterday between Groningen and Eemshaven, it is a route of just under forty kilometres or twenty-five miles. Adrian Shooter is talking of ranges of sixty miles with battery versions of Class 230 trains. So I don’t find it impossible to create a tri-mode GTW or Flirt for this lonely route at the very North of the Netherlands.
Conclusion
Stadler seem to have created a very imitative modular train concept.
As some Flirts can travel at 125 mph, could they be serious bidders to provide the new trains for the Midland Main Line?
