Why The East Of England Can Be An Offshore Hydrogen Leader
The title of this post, is the same as that of this article on the Eastern Daily Press.
This is the sub-heading.
The East of England’s connected energy system puts it in prime position to be a key player in the offshore hydrogen economy, says Anne Haase, chair of the Hydrogen East Industry Advisory Group.
These two paragraphs add a level of detail.
The East of England’s energy story is increasingly being written onshore. The region is re-writing the playbook for how a sustainable, connected energy system could take shape and deliver. The region isn’t just about tourism – we have a whole industrial ecosystem dwarfing that sector.
We are a net energy exporter to the rest of the UK. We transmit more than 30% of gas, and our infrastructure offers supply security and sustainable energy to not just our region, but to London and the South East.
This is very much a must-read article.
CO2 to SAF: A One-Step Solution
The title of this post is the same as that of this article on the Chemical Engineer.
This is the sub-heading,
Oxford spinout OXCCU has launched a demonstration plant at London Oxford Airport to trial its one-step process of turning CO2 into sustainable aviation fuel (SAF). Aniqah Majid visited the plant to investigate the benefits of its “novel” catalyst
One word in this sub-heading caught my eye.
When I was a young engineer in the Computer Techniques section in the Engineering Department at ICI Plastics Division, I did a small mathematical modelling project for this chemical engineer, using the section’s PACE 231-R analogue computer.
He was impressed and gave the 23-year-old self some advice. “You should apply that beast to catalysts.”
I have never had the chance to do any mathematically modelling of catalysts either at ICI Plastics or since, but I have invested small amounts of my own money in companies working with advanced catalysts.
So when OXCCU was picked up by one of my Google Alerts, I investigated.
I like what I found.
The three raw ingredients are.
- Green Hydrogen
- Carbon dioxide perhaps captured from a large gas-fired powerstation like those in the cluster at Keadby.
- OXCCU’s ‘novel’ catalyst, which appears to be an iron-based catalyst containing manganese, potassium, and organic fuel compounds.
I also suspect, that the process needs a fair bit of energy. These processes always seem to, in my experience.
This paragraph outlines how sustainable aviation fuel or (SAF) is created directly.
This catalyst reduces CO2 and H2 into CO and H2 via a reverse water gas shift (RWGS) process, and then subsequently turns it into jet fuel and water via Fischer-Tropsch (FT).
The Wikipedia entry for Fischer-Tropsch process has this first paragraph.
The Fischer–Tropsch process (FT) is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid hydrocarbons. These reactions occur in the presence of metal catalysts, typically at temperatures of 150–300 °C (302–572 °F) and pressures of one to several tens of atmospheres. The Fischer–Tropsch process is an important reaction in both coal liquefaction and gas to liquids technology for producing liquid hydrocarbons.
Note.
- I wouldn’t be surprised that to obtain the carbon monoxide and hydrogen or syngas for the Fischer-Tropsch process, excess hydrogen is used, so the OXCCU process may need a lot of affordable hydrogen, some of which will be converted to water in the RWGS process.
- The high temperatures and pressures for the Fischer-Tropsch process will need a lot of energy, as I predicted earlier.
But I don’t see why it won’t work with the right catalyst.
The Wikipedia entry for the Fischer-Tropsch process also says this.
Fischer–Tropsch process is discussed as a step of producing carbon-neutral liquid hydrocarbon fuels from CO2 and hydrogen.
Three references are given, but none seem to relate to OXCCU.
OXCCU have a web site, with this title.
Jet Fuel From Waste Carbon
And this mission statement underneath.
OXCCU’s mission is to develop the world’s lowest cost, lowest emission pathways to make SAF from waste carbon, enabling people to continue to fly and use hydrocarbon products but with a reduced climate impact.
It looks like they intend to boldly go.
Conclusion
My 23-year-old self may have been given some good advice.
What Happened To The Toyota Hydrogen-Powered HiLux?
I wrote about this vehicle in Toyota Unveils Prototype Hydrogen Fuel Cell Hilux, but I’ve not heard any more.
So I asked Google AI, the question in the title of this post and received this reply.
The Toyota hydrogen-powered Hilux is currently in the demonstration and evaluation phase and has not been officially confirmed for mass production. Ten prototypes were built in the UK and are undergoing testing, with some being used for customer and media demonstrations at events like the Paris Olympics. Toyota is using this project to gather data, refine its hydrogen technology, and prepare for a future European market that could see the vehicle go on sale around 2028.
A simple Google search produced this YouTube video and this article in the Toyota UK magazine.
I don’t want to drive one, as that would be illegal, but I have just added riding in one of these beasts to my bucket list.
Toyota Have Gone To The Advanced Propulsion Centre For Their Latest Project
In Toyota Leads Multi-Million-Pound Micromobility Research Project, I write about another project, where Toyota have approached the Advanced Propulsion Centre for funding and technical help. So the Advanced Propulsion Centre must be doing something right, to attract another project from Toyota.
In CoacH2 – The Next Generation Coach, I write about how the Advanced Propulsion Centre are helping to develop the powertrain for Wrightbus’s upcoming hydrogen-powered coach.
It certainly looks like the Advanced Propulsion Centre are in the middle of the net-zero transport revolution.
HiiROC And Agile Energy Unite To Advance Hydrogen Production In Scotland
The title of this post, is the same as that of this article on Offshore Energy.
This is sub-heading.
HiiROC, a UK hydrogen production company, and Agile Energy Recovery Limited, a compatriot developer of low-carbon energy parks, have partnered to evaluate the deployment of HiiROC’s proprietary process to produce low-carbon hydrogen at Agile’s Thainstone Energy Park in Inverurie, Scotland.
These three paragraphs add more detail.
It is understood that Agile is building a Swedish-style Integrated Resource Facility (IRF), which is expected to process up to 200,000 tonnes of municipal and industrial residual waste per year and produce power and heat for the surrounding area.
As for HiiROC, its Thermal Plasma Electrolysis (TPE) process reportedly requires less electricity than conventional water electrolysis and does not generate CO2 emissions, aligning with the UK’s Low Carbon Hydrogen Standard (LCHS). By leveraging the existing gas network and locating hydrogen production at the point of use, the company said it can avoid costly new infrastructure or waiting for new hydrogen pipelines or CCS clusters to come online. HiiROC’s first commercial units are planned for 2026.
The partners noted they will aim to maximize integration of their two plants, with the option to combine CO2 emissions from the IRF with HiiROC’s hydrogen to produce low-carbon e-methanol, an emerging alternative to diesel in maritime applications.
This plant would appear too be built around some impressive chemistry to process 200,000 tonnes of municipal and industrial waste per year.
Out of curiosity, I asked Google AI how much waste the London Borough of Hackney, where I live, collects per year and received this answer.
The London Borough of Hackney processed approximately 113,554 tonnes of total local authority collected waste in the 2021/22 financial year.
More recent, unaudited data for the 2023/24 financial year indicates that the total amount of household waste collected was around 313.6 kg per person. With an estimated population of nearly 280,000 people, this suggests roughly 87,800 tonnes of household waste were collected in 2023/24.
It looks to me, that a lot of councils could explore the HiiROC route to dispose of their waste.
Toyota Leads Multi-Million-Pound Micromobility Research Project
The title of this post, is the same as that of this news item from the Advanced Propulsion Centre.
These five paragraphs introduce the project.
he Advanced Propulsion Centre UK (APC) has announced the latest project funded through the UK Government’s DRIVE35 Collaborate programme.
Toyota will lead a consortium to research and develop a new lightweight battery electric vehicle in Derbyshire.
The project aims to meet the evolving needs of urban populations while accelerating the shift to zero tailpipe emission transport by validating a novel, lightweight battery electric vehicle (BEV) in the L6e category.
Underlining Toyota’s commitment to investing in the UK’s R&D capabilities, it will be manufactured at Toyota Manufacturing UK’s (TMUK) Burnaston site.
The vehicle addresses the growing demand for sustainable micro-mobility solutions and includes an integrated solar roof, increased connectivity, and lightweight sustainable materials supporting recovery and recycling.
Note.
- The vehicle will be light in weight.
- Toyota is investing in UK R & D.
- The vehicle will be built in Derbyshire at Burnaston.
I asked Google AI, what is an L6e Car and received this reply.
An L6e car is a light quadricycle in the EU vehicle classification system, defined as a light, four-wheeled vehicle with a maximum speed of 45 kph}) (28 mph)) and an unladen mass of no more than 425 kg. (excluding batteries for electric versions). It can be powered by small internal combustion engines or electric motors, and vehicles in this category are often used for urban commuting or small delivery tasks.
Note.
- Sir Alec Issigonis’s famous ADO15 Mini, which was launched in 1962, weighed 580 Kg, seated four and had an initial top speed of 75 mph.
- Sir Alec also designed racing cars and high performance Mini Coopers.
- Another partner in the project specialises in urban delivery vehicles.
I always wonder what sort of electric vehicle, the great car designer would have designed.
These are some further thoughts.
Do Toyota Build Microcars In Japan?
I asked Google AI, the question in the title of this section and received this answer.
Yes, Toyota builds microcars in Japan, and the Toyota C+pod is one example. While Toyota previously focused on larger vehicles, it now manufactures ultra-compact electric vehicles like the C+pod for the Japanese market to meet customer demand for small city cars.
The Toyota C+Pod has this Wikipedia entry, which gives these details.
- Two seats.
- 9.2 KW electric motor.
- 670-690 Kg weight.
- 37 mph.
- 93 mile range.
- The car has air conditioning, air-bags and heated seats.
The number of seats, speed and range would appear to be ideal for a city-car.
Could The Vehicle Be Hydrogen Powered?
I asked Google AI, if small lightweight hydrogen fuel cells exist and received this answer.
Yes, small, lightweight hydrogen fuel cells do exist and are commercially available for various applications, ranging from educational kits to power sources for drones and portable electronics.
I wouldn’t be surprised if the project needed a hydrogen fuel cell of a particular weight, size and power, someone could built it, by scaling an existing design.
Could The Vehicles Be Self Driving?
Not probably now, but as the technology gets more sophisticated, I suspect that it will happen.
Could The Vehicles Replace The Invacar?
This article in The Times is entitled Bring Back Three-Wheeled Cars For Disabled Drivers, Reform Urges.
I would expect that, if Toyota, the Advanced Propulsion Centre and their partners did a comprehensive job, then Toyota’s new car could serve the same purpose as an Invacar, much better in a zero-carbon manner.
There Is This Video Of A Toyota C-Pod.
Conclusion
I believe this project could come up with something special.
Rolls-Royce Successfully Tests First Pure Methanol Marine Engine – Milestone For More Climate-Friendly Propulsion Solutions
The title of this post, is the same as that of this press release from Rolls-Royce.
These four bullet points act as sub-headings.
- World first: first high-speed 100 percent methanol engine for ships successfully tested
- Cooperation: Rolls-Royce, Woodward L’Orange and WTZ Roßlau are developing sustainable propulsion technology in the meOHmare research project
- Green methanol: CO2-neutral, clean and safe marine fuel
- Dual-fuel engines as a bridging technology on the road to climate neutrality
Rolls-Royce has successfully tested the world’s first high-speed marine engine powered exclusively by methanol on its test bench in Friedrichshafen. Together with their partners in the meOHmare research project, Rolls-Royce engineers have thus reached an important milestone on the road to climate-neutral and environmentally friendly propulsion solutions for shipping.
“This is a genuine world first,” said Dr. Jörg Stratmann, CEO of Rolls-Royce Power Systems AG. “To date, there is no other high-speed engine in this performance class that runs purely on methanol. We are investing specifically in future technologies in order to open up efficient ways for our customers to reduce CO2 emissions and further expand our leading role in sustainable propulsion systems.”
Rolls-Royce’s goal is to offer customers efficient ways to reduce their CO2 emissions, in-line with the ‘lower carbon’ strategic pillar of its multi-year transformation programme. The project also aligns with the strategic initiative in Power Systems to grow its marine business.
These are some questions.
Why Methanol?
Rolls-Royce answer this question in the press release.
Green methanol is considered one of the most promising alternative fuels for shipping. If it is produced using electricity from renewable energies in a power-to-X process, its operation is CO2-neutral. Compared to other sustainable fuels, methanol is easy to store, biodegradable, and causes significantly fewer pollutants.
“For us, methanol is the fuel of the future in shipping – clean, efficient, and climate-friendly. It burns with significantly lower emissions than fossil fuels and has a high energy density compared to other sustainable energy sources,” said Denise Kurtulus.
Note that Denise Kurtulus is Senior Vice President Global Marine at Rolls-Royce.
Could Methanol-Powered Engines Be Used In Railway Locomotives?
Given, there are hundreds of railway locomotives, that need to be decarbonised, could this be handled by a change of fuel to methanol?
I asked Google AI, the question in the title of this section and received the following answer.
Yes, methanol-powered engines can be used in railway locomotives, but they require a modification like high-pressure direct injection (HPDI) technology to be used in traditional compression ignition (CI) diesel engines. These modified engines typically use methanol as the primary fuel with a small amount of diesel injected to act as a pilot fuel for ignition, a process known as “pilot ignition”. Research and simulations have shown that this approach can achieve performance and thermal efficiencies close to those of standard diesel engines
From the bullet points of this article, it looks like Rolls-Royce have this pilot ignition route covered.
How Easy Is Methanol To Handle?
Google AI gave this answer to the question in the title of this section.
Methanol is not easy to handle safely because it is a highly flammable, toxic liquid that can be absorbed through the skin, inhaled, or ingested. It requires rigorous safety measures, proper personal protective equipment (PPE), and good ventilation to mitigate risks like fire, explosion, and severe health consequences, including blindness or death.
It sounds that it can be a bit tricky, but then I believe with the right training much more dangerous chemicals than methanol can be safety handled.
How Easy Is Green Methanol To Produce?
Google AI gave this answer to the question in the title of this section.
Producing green methanol is not easy; it is currently more expensive and capital-intensive than traditional methods due to high production costs, feedstock constraints, and the need for specialized infrastructure. However, new technologies are making it more feasible, with methods that combine renewable energy with captured carbon dioxide and renewable hydrogen to synthesize methanol.
Production methods certainly appear to be getting better and greener.
Which Companies Produce Methanol In The UK?
Google AI gave this answer to the question in the title of this section.
While there are no major, existing methanol production companies in the UK, Proman is planning to build a green methanol plant in the Scottish Highlands, and other companies like Wood PLC and HyOrc are involved in the engineering and construction of methanol production facilities in the UK. Several UK-based companies also act as distributors or suppliers for products, such as Brenntag, Sunoco (via the Anglo American Oil Company), and JennyChem.
It does appear, that we have the capability to build methanol plants and supply the fuel.
How Is Green Methanol Produced?
Google AI gave this answer to the question in the title of this section.
Green methanol is produced by combining carbon dioxide and hydrogen under heat and pressure, where the hydrogen is created using renewable electricity and the carbon dioxide is captured from sustainable sources like biomass or industrial emissions. Two main pathways exist e-methanol uses green hydrogen and captured carbon dioxide, while biomethanol is made from the gasification of biomass and other organic waste.
Note.
- We are extremely good at producing renewable electricity in the UK.
- In Rolls-Royce To Be A Partner In Zero-Carbon Gas-Fired Power Station In Rhodesia, I discuss how carbon dioxide is captured from a power station in Rhodesia, which is a suburb of Worksop.
In the Rhodesia application, we have a Rolls-Royce mtu engine running with carbon-capture in a zero-carbon manner, producing electricity and food-grade carbon-dioxide, some of which could be used to make methanol to power the Rolls-Royce mtu engines in a marine application.
I am absolutely sure, that if we need green methanol to power ships, railway locomotives and other machines currently powered by large diesel engines, we will find the methods to make it.
What Are The Green Alternatives To Methanol For Ships?
This press release from Centrica is entitled Investment in Grain LNG, and it gives hints as to their plans for the future.
This heading is labelled as one of the key highlights.
Opportunities for efficiencies to create additional near-term value, and future development options including a combined heat and power plant, bunkering, hydrogen and ammonia.
Bunkering is defined in the first three paragraphs of its Wikipedia entry like this.
Bunkering is the supplying of fuel for use by ships (such fuel is referred to as bunker), including the logistics of loading and distributing the fuel among available shipboard tanks. A person dealing in trade of bunker (fuel) is called a bunker trader.
The term bunkering originated in the days of steamships, when coal was stored in bunkers. Nowadays, the term bunker is generally applied to the petroleum products stored in tanks, and bunkering to the practice and business of refueling ships. Bunkering operations take place at seaports and include the storage and provision of the bunker (ship fuels) to vessels.
The Port of Singapore is currently the largest bunkering port in the world. In 2023, Singapore recorded bunker fuel sales volume totaling 51,824,000 tonnes, setting a new industry standard.
Note.
- After Rolls-Royce’s press release, I suspect that methanol should be added to hydrogen and ammonia.
- I don’t think Centrica will be bothered to supply another zero-carbon fuel.
- I can see the Isle of Grain providing a lot of fuel to ships as they pass into London and through the English Channel.
- Centrica have backed HiiROC technology, that makes hydrogen efficiently.
I can see the four fuels ammonia, hydrogen, LNG and methanol competing with each other.
What Are The Green Alternatives To Methanol For Railway Locomotives?
The same fuels will be competing in the market and also Hydrotreated Vegetable Oil (HVO) will be used.
The Thoughts Of Chris O’Shea
This article on This Is Money is entitled Centrica boss has bold plans to back British energy projects – but will strategy pay off?.
The article is basically an interview with a reporter and gives O’Shea’s opinions on various topics.
Chris O’Shea is CEO of Centrica and his Wikipedia entry gives more details.
These are his thoughts.
On Investing In Sizewell C
This is a paragraph from the article.
‘Sizewell C will probably run for 100 years,’ O’Shea says. ‘The person who will take the last electron it produces has probably not been born. We are very happy to be the UK’s largest strategic investor.’
Note.
- The paragraph shows a bold attitude.
- I also lived near Sizewell, when Sizewell B was built and the general feeling locally was that the new nuclear station was good for the area.
- It has now been running for thirty years and should be good for another ten.
Both nuclear power stations at Sizewell have had a good safety record. Could this be in part, because of the heavy engineering tradition of the Leiston area?
On Investing In UK Energy Infrastructure
This is a paragraph from the article
‘I just thought: sustainable carbon-free electricity in a country that needs electricity – and we import 20 per cent of ours – why would we look to sell nuclear?’ Backing nuclear power is part of O’Shea’s wider strategy to invest in UK energy infrastructure.
The UK certainly needs investors in UK energy infrastructure.
On Government Support For Sizewell C
This is a paragraph from the article.
Centrica’s 500,000 shareholders include an army of private investors, many of whom came on board during the ‘Tell Sid’ privatisations of the 1980s and all of whom will be hoping he is right. What about the risks that deterred his predecessors? O’Shea argues he will achieve reliable returns thanks to a Government-backed financial model that enables the company to recover capital ploughed into Sizewell C and make a set return.
I have worked with some very innovative accountants and bankers in the past fifty years, including an ex-Chief Accountant of Vickers and usually if there’s a will, there’s a solution to the trickiest of financial problems.
On LNG
These are two paragraphs from the article.
Major moves include a £200 million stake in the LNG terminal at Isle of Grain in Kent.
The belief is that LNG, which produces significantly fewer greenhouse gas emissions than other fossil fuels and is easier and cheaper to transport and store, will be a major source of energy for the UK in the coming years.
Note.
- Centrica are major suppliers of gas-powered Combined Heat and Power units were the carbon dioxide is captured and either used or sold profitably.
- In at least one case, a CHP unit is used to heat a large greenhouse and the carbon dioxide is fed to the plants.
- In another, a the gas-fired Redditch power station, the food-grade carbon dioxide is sold to the food and construction industries.
- Grain LNG Terminal can also export gas and is only a short sea crossing from gas-hungry Germany.
- According to this Centrica press release, Centrica will run low-carbon bunkering services from the Grain LNG Terminal.
I analyse the investment in Grain LNG Terminal in Investment in Grain LNG.
On Rough Gas Storage
These are three paragraphs from the article.
O’Shea remains hopeful for plans to develop the Rough gas storage facility in the North Sea, which he re-opened in 2022.
The idea is that Centrica will invest £2 billion to ‘create the biggest gas storage facility in the world’, along with up to 5,000 jobs.
It could be used to store hydrogen, touted as a major energy source of the future, provided the Government comes up with a supportive regulatory framework as it has for Sizewell.
The German AquaVentus project aims to bring at least 100 GW of green hydrogen to mainland Germany from the North Sea.
This map of the North Sea, which I downloaded from the Hydrogen Scotland web site, shows the co-operation between Hydrogen Scotland and AquaVentus
Note.
- The yellow AquaDuctus pipeline connected to the German coast near Wilhelmshaven.
- There appear to be two AquaDuctus sections ; AQD 1 and AQD 2.
- There are appear to be three proposed pipelines, which are shown in a dotted red, that connect the UK to AquaDuctus.
- The Northern proposed pipeline appears to connect to the St. Fergus gas terminal on the North-East tip of Scotland.
- The two Southern proposed pipelines appear to connect to the Easington gas terminal in East Yorkshire.
- Easington gas terminal is within easy reach of the massive gas stores, which are being converted to store hydrogen at Aldbrough and Rough.
- The blue areas are offshore wind farms.
- The blue area straddling the Southernmost proposed pipe line is the Dogger Bank wind farm, is the world’s largest offshore wind farm and could eventually total over 6 GW.
- RWE are developing 7.2 GW of wind farms between Dogger Bank and Norfolk in UK waters, which could generate hydrogen for AquaDuctus.
This cooperation seems to be getting the hydrogen Germany needs to its industry.
It should be noted, that Germany has no sizeable hydrogen stores, but the AquaVentus system gives them access to SSE’s Aldbrough and Centrica’s Rough hydrogen stores.
So will the two hydrogen stores be storing hydrogen for both the UK and Germany?
Storing hydrogen and selling it to the country with the highest need could be a nice little earner.
On X-energy
These are three paragraphs from the article.
He is also backing a £10 billion plan to build the UK’s first advanced modular reactors in a partnership with X-energy of the US.
The project is taking place in Hartlepool, in County Durham, where the existing nuclear power station is due to reach the end of its life in 2028.
As is the nature of these projects, it involves risks around technology, regulation and finance, though the potential rewards are significant. Among them is the prospect of 2,500 jobs in the town, where unemployment is high.
Note.
- This is another bold deal.
- I wrote in detail about this deal in Centrica And X-energy Agree To Deploy UK’s First Advanced Modular Reactors.
- Jobs are mentioned in the This is Money article for the second time.
I also think, if it works to replace the Hartlepool nuclear power station, then it can be used to replace other decommissioned nuclear power stations.
On Getting Your First Job
These are three paragraphs from the article.
His career got off to a slow start when he struggled to secure a training contract with an accountancy firm after leaving Glasgow University.
‘I had about 30, 40 rejection letters. I remember the stress of not having a job when everyone else did – you just feel different,’ he says.
He feels it is ‘a duty’ for bosses to try to give young people a start.
I very much agree with that. I would very much be a hypocrite, if I didn’t, as I was given good starts by two companies.
On Apprenticeships
This is a paragraph from the article.
‘We are committed to creating one new apprenticeship for every day of this decade,’ he points out, sounding genuinely proud.
I very much agree with that. My father only had a small printing business, but he was proud of the apprentices he’d trained.
On Innovation
Centrica have backed three innovative ideas.
- heata, which is a distributed data centre in your hot water tank, which uses the waste heat to give you hot water.
- HiiROC, which is an innovative way to generate affordable hydrogen efficiently.
- Highview Power, which stores energy as liquid air.
I’m surprised that backing innovations like these was not mentioned.
Conclusion
This article is very much a must read.
45 schools Benefit From Rail Safety Resources Supported By Lumo And Hull Trains
The title of this post, is the same as that of this article on The Shields Gazette.
This is the sub-heading.
The UK’s leading open access rail operators, Lumo and Hull Trains, are celebrating supporting the delivery of vital rail safety resources to 45 schools across the UK over the past year.
These three paragraphs add more detail.
In association with the Rail Safe Friendly Programme, the operators’ involvement has led to a social value impact of over £724,000, directly educating thousands of young people.
The programme is dedicated to spreading the vital message of rail safety among young people, educators and parents in schools across the UK. Lumo and Hull Trains have supported the important initiative for the past two years, with their support renewed for a third.
As part of the partnership, Lumo took over the Metrocentre’s ‘mini express train’ to highlight the issue of rail safety to families and children visiting the shopping centre during the school holidays in 2024. The project secured industry recognition at the recent Corporate Engagement Awards.
It’s not just in the UK, that this type of excellent engagement is being setup.
This train is the world’s first hydrogen-powered train to enter passenger service, between Hamburg and Cuxhaven in Germany.
When I rode the train, a German schoolboy told me, that their school had given them safety lessons about hydrogen.
Unlocking Efficiency With Cryogenic Cooling Of GaN Traction Inverters
The title of this post, is the same as this insight on the Ricardo web site.
This is the introduction.
As the mobility sector accelerates toward zero-carbon propulsion, hydrogen fuel cell systems (HFCS) are emerging as a cornerstone technology for aviation, marine, and long-haul road transport. Among the most promising innovations in this space is the use of liquid hydrogen (LH₂) not only as a fuel source but also as a cryogenic coolant for electric powertrains. This dual-purpose approach offers transformative potential in system efficiency, packaging, and weight reduction—especially when paired with Gallium Nitride (GaN) semiconductors.
It is a very simple concept, but it appears to give worthwhile efficiency gains.
This was the article’s conclusion.
Ricardo’s cryogenic GaN inverter concept represents a bold leap toward ultra-efficient, lightweight, and integrated hydrogen propulsion systems. While challenges remain in materials, packaging, and reliability, the experimental results are compelling. With efficiencies nearing 99.8% and mass reductions over 50%, cryogenic cooling could redefine the future of electric mobility.
As the hydrogen economy matures, innovations like this will be pivotal in delivering clean, scalable, and high-performance solutions across all mobility sectors.
I very much suggest, that you take the time to read the whole insight.
Using The Concept In a Liquid Hydrogen Carrier
This Wikipedia entry describes the design and operation of an ocean-going liquid hydrogen carrier.
This is a paragraph.
Similar to an LNG carrier the boil off gas can be used for propulsion of the ship.
Ricardo’s concept would appear to be advantageous in the design of liquid hydrogen carriers and I would expect, it could also be applied to the design of LNG carriers.
I would not be surprised to see liquid hydrogen and LNG carriers were the first application of Ricardo’s concept.
This Wikipedia entry describes the Suiso Frontier, which is the world’s only liquid hydrogen carrier.
I believe that Ricardo’s concept could lead to the construction of a more of these ships. Will they mean that liquid hydrogen carriers will deliver hydrogen from sunny climes to places like Europe, Japan, Korea and Canada.
The concept would also enable efficient small liquid hydrogen carriers, that could deliver hydrogen on routes like the North of Scotland to Germany.
Using The Concept In A Railway Locomotive
I could see freight locomotives being designed as a large liquid hydrogen tank with appropriately-sized fuel cells and added electrical gubbins.
- They would be self-powered and would not require any electrification.
- They would be much quieter than current diesels.
- They could pull the heaviest freight trains, between Europe and Asia.
- They could even pull passenger trains, if an electrical hotel supply were to be arranged.
- They could be designed with very long ranges.
But above all they would be zero-carbon.
Note that I’ve written about long freight routes before.
- China, Russia And The EU’s Intermarium Bloc
- How To Move 100,000 Containers A Year Between Germany And China
- Georgia, Azerbaijan and Iran Discuss New Freight Corridor To link India And Europe
- Finland And Norway To Explore Building Arctic Rail Link
- A New Gateway To China: Europe Prepares For The Launch Of Baku–Tbilisi–Kars Railway
I believe that a long-distance liquid-hydrogen locomotive, that was based on the Ricardo concept, would be ideal for some of these routes.
A Specialised Hydrogen Delivery Train
In April 2022, I wrote The TruckTrain, where this is a simple description of the concept.
The Basic Design Concept
The leaflet on their web site describes the concept.
This visualisation at the bottom of the leaflet shows four TruckTrains forming a train carrying twelve intermodal containers, each of which I suspect are 20 feet long.
I believe that the TruckTrain concept could be converted into a hydrogen delivery train.
- It would be an appropriate length.
- It would be powered by the on-board hydrogen.
- The hydrogen would be stored as liquid hydrogen.
It would be able to go most places on the UK rail network.
Conclusion
Ricardo’s concept could revolutionise the use of hydrogen.
The Anonymous Widower
