Hydrogen In Aviation Offers Potential For Growth And Deeper Emissions Reductions, New Study Shows

The title of this post, is the same as that of this press release from Rolls-Royce.

These five paragraphs compose the press release.

Rolls-Royce, easyJet, Heathrow and University College London Air Transportation Systems Lab (UCL ATSLab) published a report highlighting how hydrogen-powered aircraft could enable European and UK aviation to cut carbon emissions while supporting future growth.

The study, Enabling Hydrogen in the European Aviation Market, found that hydrogen in aviation offers a unique opportunity to achieve both emissions reduction and market expansion. The analysis shows that introducing hydrogen alongside Sustainable Aviation Fuel (SAF) can accelerate progress towards net zero, particularly when policy incentives reward low-carbon fuels and if hydrogen were to be included within the EU’s SAF mandate.

The research also found that targeted hydrogen infrastructure at around 20 major European airports, including Heathrow, could deliver more than 80% of the emissions benefits of full hydrogen availability across the continent. Concentrating investment at key ‘hydrogen hubs’ would therefore provide a practical and cost-effective path to early adoption.

Further modelling indicates that the earlier novel technologies, such as hydrogen, can be introduced, the more opportunity they present for CO2 emission reductions, underscoring the value of early technological transition where it is financially and technically viable.

The study is underpinned by UCL ATSLab’s Airline Behaviour Model (ABM), which represents the complexity of airline decision-making through specific behavioural variables. Building on this, the research evaluates how fuel costs, incentives and new technologies shape airline responses. This provides a research-based, realistic picture of how hydrogen adoption could evolve, highlighting both opportunities and potential challenges for adoption.

Note, these two sentences recommending early adoption of hydrogen.

  1. Concentrating investment at key ‘hydrogen hubs’ would therefore provide a practical and cost-effective path to early adoption.
  2. Further modelling indicates that the earlier novel technologies, such as hydrogen, can be introduced, the more opportunity they present for CO2 emission reductions.

I also suspect, that introducing hydrogen early, feeds back  to reduce Co2 emissions.

But what is Trump’s considered view on hydrogen aircraft?

Google AI gives this answer to my question.

Donald Trump’s view on hydrogen for transportation, including potential use in aircraft, is highly skeptical due to perceived safety risks and effectiveness concerns, which generally aligns with his broader opposition to green energy initiatives. He has specifically criticized hydrogen-powered vehicles as being dangerous and “prone to blowing up”.

Note.

  1. I used to work in a hydrogen factory and it’s still producing hydrogen.
  2. I doubt Trump gets on well with Jennifer Rumsey, who is CEO of Cummins, who are one of the world’s largest diesel-engine companies, who are following a zero-carbon route.
  3. Is Formula One Likely To Go To Hydrogen Fuel?  This would set the Cat Among The Pigeons

I also feel that this University College London study will create a string of converts to hydrogen.

Is Carbon Black Used To Make Offshore Electrical Cable?

I asked Google AI, the answer to this question and received this answer.

 

Yes, carbon black is extensively used to make offshore electrical cables. It serves two primary functions: providing electrical conductivity to specific components and offering UV protection to outer jacketing materials.

That seems a positive answer.

It also could be a very complementary one.

HiiROC have a process that splits any hydrocarbon gas including natural gas, chemical plant off gas and biomethane, into turquoise hydrogen and carbon black.

Two methods of bringing energy to the shore from an offshore wind farm are electricity and hydrogen, through a cable or pipe respectively.

This looks to me, that there could be a possibility to use one of Baldrick’s cunning hybrid plans to bring energy onshore using both hydrogen and electricity.

Effectively, the transmission and use of the system, would use both the hydrogen and carbon black produced by HiiROC.

Network Rail’s Test Track Take Centre Stage As Hydrogen Is Delivered By Rail For The First Time

The title of this post, is the same as that of this press release from GeoPura.

These three paragraphs introduce the story.

Network Rail, working with rail and energy partners Freightliner and GeoPura, has transported hydrogen for the first time on Britain’s rail network, marking a major step forward for both the rail and energy sectors.

The milestone was achieved yesterday (Wednesday 3 December) at Network Rail’s Test Tracks* site in Tuxford, where freight operator Freightliner hauled a train of gas containers from Doncaster to High Marnham – marking Britain’s first shipment of hydrogen by rail.

It was part of a rail and energy industry innovation event showcasing several hydrogen initiatives. This included the first re-engineered hydrogen-powered shunting locomotive – seen as a step towards replacing diesel – another milestone towards the rail industry’s goal of becoming net zero. The event also demonstrated HPU hydrogen-powered generators, lighting towers and support vehicles.

These two paragraphs describe Network Rail’s test track at Tuxford and GeoPura’s hydrogen production facility at High Marnham.

Network Rail’s site at Tuxford runs all the way to High Marnham, where it sits adjacent to HyMarnham Power, the UK’s largest green hydrogen production facility operated by GeoPura and JG Pears. Built on the site of a former coal-fired power station, HyMarnham Power is one of the world’s first rail-connected hydrogen production facilities, and Network Rail’s Tuxford site will be the world’s first net-zero railway testing facility.

Currently, hydrogen is transported by road. This breakthrough marks a major step towards the rail network becoming a ready-made hydrogen distribution system, a rolling pipeline, with connections to all major industrial and urban centres across Britain – proving the practical capability of rail to transport hydrogen at scale. Hydrogen will also be utilised to decarbonise wider rail operations, from construction to ongoing maintenance and off-grid operations.

This OpenRailwayMap shows Tuxford and High Marnham.

Note.

  1. The blue arrow is Tuxford West junction.
  2. The North-South red track is the East Coast Main Line. East-West track indicated by the blue arrow is Network Rail’s Test Track
  3. The grey area, to the South of the Test Track in the East is the former site of High Marnham power station, where GeoPura have their hydrogen facility.
  4. If you continue East on the Test Track it connects to the Sheffield and Lincoln Line at Pye Wipe junction.

Sheffield could be the sort of city, that would need a lot of hydrogen to decarbonise.

Has  Hydrogen Been Transported From ICI’s Former Site At Runcorn By Rail

I ask this question, as I used to work at Runcorn in the 1960s, and I don’t remember seeing any hydrogen railway wagons.

I asked Google AI, the question in the title of this section and received this answer.

Hydrogen is typically transported from the INEOS (formerly ICI) site in Runcorn via pipeline or by road in cryogenic liquid tanker trucks or gaseous tube trailers, but it has not been historically transported by rail from that specific site.
The first ever trial shipment of hydrogen by rail on Britain’s network took place only very recently, in December 2025, as part of an industry innovation event. This trial involved transporting hydrogen containers from Doncaster to High Marnham, adjacent to the HyMarnham Power green hydrogen production facility.

It looks like my memory and Google AI agree.

Centrica Energy And Exodus Sign Landmark LNG Agreement

The title of this post, is the same as that of this press release from Centrica.

This is the sub-heading.

Centrica Energy has announced the signing of a long-term Sale and Purchase Agreement (SPA) to supply liquefied natural gas (LNG) to Exodus for Honduras, marking a new milestone in the country’s energy development.

These two paragraphs add more details.

Under the terms of the agreement, Centrica will deliver approximately six LNG cargoes per year to Exodus through a ship-to-ship operation into the Floating Storage Unit (FSU) Bilbao Knutsen, located in Puerto Cortes. The 15-year contract is expected to commence in 2026.

“This agreement reflects Centrica Energy’s commitment to expanding global LNG access through strategic partnerships,” said Arturo Gallego, Global Head of LNG at Centrica Energy. “By leveraging our global reach and operational expertise, we’re proud to support Exodus and Honduras in its journey toward a more sustainable and resilient energy future.”

It looks a good deal for Centrica, that has been snatched from under the American’s noses.

I also asked Google AI, if Honduras produced any natural gas and received this reply.

No, Honduras does not produce natural gas, but it is importing it through a new liquefied natural gas (LNG) agreement that begins in 2026. The country relies on imports to meet its energy needs, and this new deal aims to diversify its energy mix and provide cleaner energy for power generation.

That’s clear and it’s interesting that Honduras are looking to provide cleaner energy.

These two paragraphs from Centrica’s press release add details on power generation in Honduras.

The LNG will be transported to the Brassavola Combined Cycle Power Plant, an operating 150 MW thermal facility with its combined cycle under construction and set to reach 240 MW of power capacity, marking the first-ever import of natural gas for power generation in Honduras. This initiative represents a significant step toward diversifying the nation’s energy mix and reducing its reliance on less environmentally friendly fossil fuels.

Once operational, the FSU will serve as the backbone of LNG storage at a new terminal currently under construction on Honduras’ Caribbean coast. The project is designed to enhance energy security, improve generation efficiency, and support industrial growth.

This article on Riviera is entitled Honduras Turns To LNG To Meet Energy Needs and provides these points.

  • Honduras is grappling with a 250 MW power shortage.
  • Genesis Energías is spearheading efforts to introduce a reliable and cost-effective energy source by importing liquefied natural gas (LNG).
  • Hyundai, who are one of Centrica’s partners in HiiROC, are converting the Bilbao Knutsen for its new role as a Floating Storage Unit (FSU).

It would certainly help Honduras’s economy, if they had more power generation.

I asked Google AI, if Honduras was developing offshore wind power and received this reply.

While Honduras has been actively developing onshore wind power for over a decade, there is currently no information to suggest it is developing offshore wind power projects. The country’s wind energy development has focused exclusively on land-based projects, with a number of operational farms and more in the pipeline.

I also asked Google AI if Honduras was developing solar power and received this reply.

Yes, Honduras is actively and significantly developing its solar power capacity as a cornerstone of its national energy strategy. The country has been a regional leader in solar energy penetration and continues to invest heavily in new projects to reduce its dependence on fossil fuels.

But, whether its offshore wind, onshore wind or solar power, these renewals will need backup and the 240 MW Brassavola Combined Cycle Power Plant, will be a good start.

I have some further thoughts.

Does HiiROC Have A Part To Play?

If would be good, if the 240 MW Brassavola Combined Cycle Power Plant could be zero-carbon, so that Honduras could be more zero-carbon.

Consider.

  • Centrica own part of HiiROC, who can generate turquoise hydrogen efficiently from natural gas.
  • Honduras will from 2026, have plenty of natural gas.
  • In Hydrogen Milestone: UK’s First Hydrogen-to-Power Trial At Brigg Energy Park, I talked about how Centrica powered Brigg power station with a hydrogen blend.
  • If the Brassavola Combined Cycle Power Plant was reasonably-modern like Brigg, I suspect it could be run on hydrogen or a hydrogen-blend.
  • A reliable supply of hydrogen in Honduras would have its uses.

I wouldn’t be surprised to see a HiiROC plant in Honduras to help decarbonise the country.

HiiROC Creates A Lot Of Carbon Black

When a HiiROC system produces turquoise hydrogen, it produces carbon black as a by-product.

I asked Google AI, if Honduras has a use for carbon black, and received this reply.

Honduras likely has a use for carbon black because the material is a vital component in the production of many common industrial and consumer goods that are used globally. The primary applications are universal across most countries, including those in Central America.

But carbon black can also be used to improve poor agricultural land.

So I asked, Google AI, if Honduras has a lot of land to improve and received this reply.

Yes, Honduras has significant land to improve, but this is complicated by issues like deforestation, land degradation, and a lack of clear land rights for many communities. There is a need to balance economic activities like coffee plantations with conservation, improve sustainable agriculture practices, and address illegal land occupation.

It seems to me, that a sensible hollistic approach could use some of the carbon black.

I also believe, that there are many universities, who could advise Honduras on land restoration.

Does Highview Power Have A Part To Play?

Consider.

  • Centrica are one of the backers of Highview Power, who are building their first two environmentally-friendly liquid air batteries in the UK.
  • Their flagship battery is a 300 MW/3.2 GWh monster that can incorporate a stability island, that controls the grid.
  • Highview Power’s batteries are zero-carbon, with a 40-50 year life.

As a Control Engineer, I believe that one of these batteries would be superb backup for the Brassavola Combined Cycle Power Plant and all those renewables.

Where Will Centrica Get Their LNG For Honduras?

I have already reported on two deals, where Centrica is purchasing LNG.

I can expect more deals like this around the world.

Also, as the Grain LNG Terminal has the ability to export LNG could we be seeing UK natural gas being exported by Centrica to Honduras and the other countries hinted at in the PTT purchase?

Are Centrica Proposing A Comprehensive Solution To A Nation’s Power Problem?

It certainly looks like they are.

And Honduras would be getting a zero-carbon energy system.

This could be repeated all around the world.

 

Conclusion

This certainly looks like a good deal for Centrica, that can be repeated in other places.

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.

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.

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.

How Will The UK Power All These Proposed Data Centres?

On Wednesday, a cardiologist friend asked me if we have enough power to do Trump’s UK AI, so I felt this post might be a good idea.

Artificial Intelligence Gave This Answer

I first asked Google AI, the title of this post and received this reply.

The UK will power proposed data centres using a mix of grid-supplied low-carbon electricity from sources like offshore wind and through on-site renewable generation, such as rooftop solar panels. Data centre operators are also exploring behind-the-meter options, including battery storage and potential future nuclear power, to meet their significant and growing energy demands. However, the UK’s grid infrastructure and high energy prices present challenges, with industry calls for grid reform and inclusion in energy-intensive industry support schemes to facilitate sustainable growth.

Google also pointed me at the article on the BBC, which is entitled Data Centres To Be Expanded Across UK As Concerns Mount.

This is the sub-heading.

The number of data centres in the UK is set to increase by almost a fifth, according to figures shared with BBC News.

These are the first three paragraphs.

Data centres are giant warehouses full of powerful computers used to run digital services from movie streaming to online banking – there are currently an estimated 477 of them in the UK.

Construction researchers Barbour ABI have analysed planning documents and say that number is set to jump by almost 100, as the growth in artificial intelligence (AI) increases the need for processing power.

The majority are due to be built in the next five years. However, there are concerns about the huge amount of energy and water the new data centres will consume.

Where Are The Data Centres To Be Built?

The BBC article gives this summary of the locations.

More than half of the new data centres would be in London and neighbouring counties.

Many are privately funded by US tech giants such as Google and Microsoft and major investment firms.

A further nine are planned in Wales, one in Scotland, five in Greater Manchester and a handful in other parts of the UK, the data shows.

While the new data centres are mostly due for completion by 2030, the biggest single one planned would come later – a £10bn AI data centre in Blyth, near Newcastle, for the American private investment and wealth management company Blackstone Group.

It would involve building 10 giant buildings covering 540,000 square metres – the size of several large shopping centres – on the site of the former Blyth Power Station.

Work is set to begin in 2031 and last for more than three years.

Microsoft is planning four new data centres in the UK at a total cost of £330m, with an estimated completion between 2027 and 2029 – two in the Leeds area, one near Newport in Wales, and a five-storey site in Acton, north-west London.

And Google is building a data centre in Hertfordshire, an investment worth £740m, which it says will use air to cool its servers rather than water.

There is a map of the UK, with dots showing data centres everywhere.

One will certainly be coming to a suitable space near you.

Concerns Over Energy Needs

These three paragraphs from the BBC article, talk about the concerns about energy needs.

According to the National Energy System Operator, NESO, the projected growth of data centres in Great Britain could “add up to 71 TWh of electricity demand” in the next 25 years, which it says redoubles the need for clean power – such as offshore wind.

Bruce Owen, regional president of data centre operator Equinix, said the UK’s high energy costs, as well as concerns around lengthy planning processes, were prompting some operators to consider building elsewhere.

“If I want to build a new data centre here within the UK, we’re talking five to seven years before I even have planning permission or access to power in order to do that,” he told BBC Radio 4’s Today programme.

But in Renewable Power By 2030 In The UK, I calculated that by 2030 we will add these yearly additions of offshore wind power.

  • 2025 – 1,235 MW
  • 2026 – 4,807 MW
  • 2027 – 5,350 MW
  • 2028 – 4,998 MW
  • 2029 – 9,631 MW
  • 2030 – 15,263 MW

Note.

  1. I have used pessimistic dates.
  2. There are likely to be more announcements of offshore wind power in the sea around the UK, in the coming months.
  3. As an example in Cerulean Winds Submits 1 GW Aspen Offshore Wind Project In Scotland (UK), I talk about 3 GW of offshore wind, that is not included in my yearly totals.
  4. The yearly totals add up to a total of 58,897 MW.

For solar power, I just asked Google AI and received this answer.

The UK government aims to have between 45 and 47 gigawatts (GW) of solar power capacity by 2030. This goal is set out in the Solar Roadmap and aims to reduce energy bills and support the UK’s clean power objectives. The roadmap includes measures like installing solar on new homes and buildings, exploring solar carports, and improving access to rooftop solar for renters.

Let’s assume that we only achieve the lowest value of 45 GW.

But that will still give us at least 100 GW of renewable zero-carbon power.

What will happen if the wind doesn’t blow and the sun doesn’t shine?

I have also written about nuclear developments, that were announced during Trump’s visit.

This is an impressive array of nuclear power, that should be able to fill in most of the weather-induced gaps.

In Renewable Power By 2030 In The UK, I also summarise energy storage.

For pumped storage hydro, I asked Google AI and received this answer.

The UK’s pumped storage hydro (PSH) capacity is projected to more than double by 2030, with six projects in Scotland, including Coire Glas and Cruachan 2, potentially increasing capacity to around 7.7 GW from the current approximately 3 GW. This would be a significant step towards meeting the National Grid’s required 13 GW of new energy storage by 2030, though achieving this depends on policy support and investment.

There will also be smaller lithium-ion batteries and long duration energy storage from companies like Highview Power.

But I believe there will be another source of energy that will ensure that the UK achieves energy security.

SSE’s Next Generation Power Stations

So far two of these power stations have been proposed.

  • Keadby will be 900 MW and has this web site.
  • Ferrybridge will be 1200 MW and has this web site.

Note.

  1. Both power stations are being designed so they can run on natural gas, 100 % hydrogen or a blend of natural gas and hydrogen.
  2. Keadby will share a site with three natural gas-powered power stations and be connected to the hydrogen storage at Aldbrough, so both fuels will be available.
  3. Ferrybridge will be the first gas/hydrogen power station on the Ferrybridge site and will have its own natural gas connection.
  4. How Ferrybridge will receive hydrogen has still to be decided.
  5. In Hydrogen Milestone: UK’s First Hydrogen-to-Power Trial At Brigg Energy Park, I describe how Centrica tested Brigg gas-fired power station on a hydrogen blend.
  6. The power stations will initially run on natural gas and then gradually switch over to lower carbon fuels, once delivery of the hydrogen has been solved for each site.

On Thursday, I went to see SSE’s consultation at Knottingley for the Ferrybridge power station, which I wrote about in Visiting The Consultation For Ferrybridge Next Generation Power Station At Knottingley.

In the related post, I proposed using special trains to deliver the hydrogen from where it is produced to where it is needed.

Could HiiROC Be Used At Ferrybridge?

Consider.

  • HiiROC use a process called thermal plasma electrolysis to split any hydrocarbon gas into hydrogen and carbon black.
  • Typical input gases are chemical plant off gas, biomethane and natural gas.
  • Carbon black has uses in manufacturing and agriculture.
  • HiiROC uses less energy than traditional electrolysis.
  • There is an independent power source at Ferrybridge from burning waste, which could be used to ower a HiiROC  system to generate the hydrogen.

It might be possible to not have a separate hydrogen feed and still get worthwhile carbon emission savings.

Conclusion

I believe we will have enough electricity to power all the data centres, that will be built in the next few years in the UK.

Some of the new power stations, that are proposed to be built, like some of the SMRs and SSE’s Next Generation power stations could even be co-located with data centres or other high energy users.

In Nuclear Plan For Decommissioned Coal Power Station, I describe how at the former site of Cottam coal-fired power station, it is proposed that two Holtec SMR-300 SMRs will be installed to power advanced data centres. If the locals are objecting to nuclear stations, I’m sure that an SSE Next Generation power station, that was burning clean hydrogen, would be more acceptable.

Hydrogen Milestone: UK’s First Hydrogen-to-Power Trial At Brigg Energy Park

The title of this post, is the same as that of this press release from Centrica.

This is the sub-heading.

Centrica and HiiROC, supported by the Net Zero Technology Centre (NZTC), have successfully demonstrated the injection of hydrogen into a gas-fired peak power plant at Centrica’s Brigg Energy Park, North Lincolnshire. The trial that took place last Thursday (11 September) marks a UK first in using hydrogen to decarbonise peak power generation supplying power directly to the electricity grid.

These three opening paragraphs add detail.

HiiROC’s modular hydrogen production technology, using Thermal Plasma Electrolysis (TPE), produced hydrogen on site which was then blended at a 3% ratio for the purposes of a one-hour trial.

The trial marks a further step forward in Centrica’s ongoing efforts to advance innovative solutions for the decarbonisation of its portfolio of gas plants, demonstrating that existing gas infrastructure can operate on a hydrogen blend to provide reliable, low carbon electricity to UK homes and businesses. More broadly, the trial shows a viable route for delivering on decarbonisation readiness obligations for peaker generation as part of the UK’s journey to net zero.

It is also a key milestone in HiiROC’s journey, demonstrating the effectiveness and affordability of HiiROC’s TPE process, which produces hydrogen without CO2 emissions, making it compliant with the UK’s Low Carbon Hydrogen Standard (LCHS). By leveraging the existing gas network and co-locating hydrogen production where it is needed, operators can decarbonise without costly new infrastructure.

Note.

  1. This test was only at a low level of hydrogen.
  2. Brigg power station is a 240 MW power station, which is fuelled by natural gas.

A long journey starts with a single step.

Centrica And X-energy Agree To Deploy UK’s First Advanced Modular Reactors

The title of this post, is the same as that of this press release from Centrica.

This is the sub-heading.

Centrica and X-Energy, LLC, a wholly-owned subsidiary of X-Energy Reactor Company, LLC, today announced their entry into a Joint Development Agreement (JDA) to deploy X-energy’s Xe-100 Advanced Modular Reactors (“AMR”) in the United Kingdom.

These three paragraphs add more details.

The companies have identified EDF and Centrica’s Hartlepool site as the preferred first site for a planned U.K. fleet of up to 6 gigawatts.

The agreement represents the first stage in a new trans-Atlantic alliance which could ultimately mobilise at least £40 billion in economic value to bring clean, safe and affordable power to thousands of homes and industries across the country and substantive work for the domestic and global supply chain.

A 12-unit Xe-100 deployment at Hartlepool could add up to 960 megawatts (“MW”) of new capacity, enough clean power for 1.5 million homes and over £12 billion in lifetime economic value. It would be developed at a site adjacent to Hartlepool’s existing nuclear power station which is currently scheduled to cease generating electricity in 2028. Following its decommissioning, new reactors would accelerate opportunities for the site and its skilled workforce. The site is already designated for new nuclear under the Government’s National Policy Statement and a new plant would also play a critical role in generating high-temperature heat that could support Teesside’s heavy industries.

This is no toe-in-the-water project, but a bold deployment of a fleet of small modular reactors to provide the power for the North-East of England for the foreseeable future.

These are my thoughts.

The Reactor Design

The Wikipedia entry for X-energy has a section called Reactor Design, where this is said.

The Xe-100 is a proposed pebble bed high-temperature gas-cooled nuclear reactor design that is planned to be smaller, simpler and safer when compared to conventional nuclear designs. Pebble bed high temperature gas-cooled reactors were first proposed in 1944. Each reactor is planned to generate 200 MWt and approximately 76 MWe. The fuel for the Xe-100 is a spherical fuel element, or pebble, that utilizes the tristructural isotropic (TRISO) particle nuclear fuel design, with high-assay LEU (HALEU) uranium fuel enriched to 20%, to allow for longer periods between refueling. X-energy claims that TRISO fuel will make nuclear meltdowns virtually impossible.

Note.

  1. It is not a conventional design.
  2. Each reactor is only about 76 MW.
  3. This fits with “12-unit Xe-100 deployment at Hartlepool could add up to 960 megawatts (“MW”) of new capacity” in the Centrica press release.
  4. The 960 MW proposed for Hartlepool is roughly twice the size of the Rolls-Rpoyce SMR, which is 470 MW .
  5. Safety seems to be at the forefront of the design.
  6. I would assume, that the modular nature of the design, makes expansion easier.

I have no reason to believe that it is not a well-designed reactor.

Will Hartlepool Be The First Site?

No!

This page on the X-energy web site, describes their site in Texas, which appears will be a 320 MW power station providing power for Dow’s large site.

There appear to be similarities between the Texas and Hartlepool sites.

  • Both are supporting industry clustered close to the power station.
  • Both power stations appear to be supplying heat as well as electricity, which is common practice on large industrial sites.
  • Both use a fleet of small modular reactors.

But Hartlepool will use twelve reactors, as opposed to the four in Texas.

How Will The New Power Station Compare With The Current Hartlepool Nuclear Power Station?

Consider.

  • The current Hartlepool nuclear power station has two units with a total capacity of 1,185 MW.
  • The proposed Hartlepool nuclear power station will have twelve units with a total capacity of 960 MW.
  • My instinct as a Control Engineer gives me the feeling, that more units means higher reliability.
  • I suspect that offshore wind will make up the difference between the power output of the current and proposed power stations.

As the current Hartlepool nuclear power station is effectively being replaced with a slightly smaller station new station, if they get the project management right, it could be a painless exercise.

Will This Be The First Of Several Projects?

The press release has this paragraph.

Centrica will provide initial project capital for development with the goal of initiating full-scale activities in 2026. Subject to regulatory approval, the first electricity generation would be expected in the mid-2030s. Centrica and X-energy are already in discussions with additional potential equity partners, as well as leading global engineering and construction companies, with the goal of establishing a UK-based development company to develop this first and subsequent projects.

This approach is very similar to the approach being taken by Rolls-Royce for their small modular reactors.

Will Centrica Use An X-energy Fleet Of Advanced Modular Reactors At The Grain LNG Terminal?

This press release from Centrica is entitled Investment In Grain LNG Terminal.

This is one of the key highlights of the press release.

Opportunities for efficiencies to create additional near-term value, and future development options including a combined heat and power plant, bunkering, hydrogen and ammonia.

Note.

  1. Bunkering would be provided for ships powered by LNG, hydrogen or ammonia.
  2. Heat would be needed from the combined heat and power plant to gasify the LNG.
  3. Power would be needed from the combined heat and power plant to generate the hydrogen and ammonia and compress and/or liquify gases.

Currently, the heat and power is provided by the 1,275 MW Grain CHP gas-fired power station, but a new nuclear power station would help to decarbonise the terminal.

Replacement Of Heysham 1 Nuclear Power Station

Heysham 1 nuclear power station is part-owned by Centrica and EdF, as is Hartlepool nuclear power station.

Heysham 1 nuclear power station is a 3,000 MW nuclear power station, which is due to be decommissioned in 2028.

I don’t see why this power station can’t be replaced in the same manner as Hartlepool nuclear power station.

Replacement Of Heysham 2 Nuclear Power Station

Heysham 2 nuclear power station is part-owned by Centrica and EdF, as is Hartlepool nuclear power station.

Heysham 2 nuclear power station is a 3,100 MW nuclear power station, which is due to be decommissioned in 2030.

I don’t see why this power station can’t be replaced in the same manner as Hartlepool nuclear power station.

Replacement Of Torness Nuclear Power Station

Torness nuclear power station is part-owned by Centrica and EdF, as is Hartlepool nuclear power station.

Torness nuclear power station is a 1,290 MW nuclear power station, which is due to be decommissioned in 2030.

I don’t see why this power station can’t be replaced in the same manner as Hartlepool nuclear power station.

But the Scottish Nationalist Party may have other ideas?

What Would Be The Size Of Centrica’s And X-energy’s Fleet Of Advanced Modular Reactors?

Suppose.

  • Hartlepool, Grain CHP and Torness power stations were to be replaced by identical 960 MW ADRs.
  • Heysham 1 and Heysham 2 power stations were to be replaced by identical 1,500 MW ADRs.

This would give a total fleet size of 5,880 MW.

A paragraph in Centrica’s press release says this.

The companies have identified EDF and Centrica’s Hartlepool site as the preferred first site for a planned U.K. fleet of up to 6 gigawatts.

This fleet is only 120 MW short.

Centrica Secures Investment Stake In Gasrec Helping Boost UK Bio-LNG Ambitions

The title of this post, is the same as that of this press release from Centrica.

This is the sub-heading.

Centrica has secured a minority stake in Gasrec, the UK’s largest dual provider of bio-LNG (bio-Liquified Natural Gas) and bio-CNG (bio-Compressed Natural Gas) to the road transport sector,

These first two paragraphs give more details.

Gasrec says the investment will drive the next phase of its infrastructure ambitions, with plans to open a UK wide network of open-access refuelling stations supplying renewable bio-LNG for the decarbonisation of heavy goods vehicles.

Centrica is taking a 16% stake and becomes one of three major shareholders in Gasrec, alongside global integrated energy company bp and private family office 44 North.

I have some thoughts.

Does Running A Truck On bio-LNG or bio-CNG. Reduce Carbon Emissions?

This paragraph from the press release, gives the thoughts of Chris O’Shea, who is Group Chief Executive, Centrica.

Chris O’Shea, Group Chief Executive, Centrica plc, said: “Demand for bio-LNG for transport is growing fast as more HGV operators make the switch – drawn by a clean, ready-to-use fuel which slashes CO2 emissions by up to 85 per cent in comparison to diesel*. This investment in Gasrec enhances our collaboration with the leading company in the sector, and puts us in a strong position to energise a vital sector of the industry on its journey to net zero.”

As Centrica is a public company, with shareholders, who would take a dim view of Mr. O’Shea telling porkies, I suspect we can assume that the following is true.

Drawn by a clean, ready-to-use fuel which slashes CO2 emissions by up to 85 per cent in comparison to diesel.

The asterisk in the full quote, refers to this note.

Low Carbon Vehicle Partnership, Innovate UK and Office for Low Emission Vehicles, Low Emission Freight & Logistics Trial (LEFT), Key Findings, November 2020. Using specific feedstocks CO2 reductions of 200% are achievable.

Centrica could be being conservative with their claims.

Decarbonising Buses, Locomotives And Trucks

Despite what Elon Musk, would have us believe, electric trucks will not dominate the future of freight transport.

An electric truck would be the vehicle equivalent of asking Usain Bolt to run a hundred metres with a large refrigerator on his back.

Trucks are going to need a fuel without a weight penalty and with a long range.

I asked Google for information about Cummins diesel, natural gas and hydrogen engines and received this AI Overview.

Cummins offers engines powered by diesel, natural gas, and hydrogen. While diesel engines are well-established, Cummins is also developing both natural gas and hydrogen engines, particularly focusing on hydrogen as a pathway to zero-carbon solutions for various applications. Cummins utilizes a fuel-agnostic platform, meaning a common base engine can be adapted for different fuel types, including diesel, natural gas, and hydrogen.

Recently, GB Railfreight purchased thirty Class 99 locomotives from Stadler.

  • They can use electrification, where it exists.
  • Where electrification doesn’t exist, they can use an onboard Cummins diesel engine, which is built in Darlington.
  • In electric-mode, they have 6.2 MW of power, and are the most powerful locomotives ever to run on UK railways.
  • In diesel-mode, they have 1.8 MW of power, which is more than enough to haul a large container train in and out of Felixstowe.

I had thought that at some future date, Cummins would convert these locomotives to electro-hydrogen.

But now that Gasrec is providing bio-LNG and bio-CNG, GB Railfreight, have the option of converting both hydrogen and biomethane.

Similar logic can be applied to Wrightbus’s Streetdeck Ultroliner, one version of which is fitted with a Cummins engine, that can be converted to electric, hydrogen or natural gas, which of course includes biomethane. This page on the Wrightbus web site describes the bus.

Wrightbus are also going back into coach manufacture, as I wrote about in Wrightbus Goes Back To The Future As It Relaunches The Contour Coach. As with the Streetdeck Ultroliner, Cummins seem to be providing one of the power units.

It seems to me, that the zero- and low-carbon revolution in transport will generate a need for the availability of biomethane, hydrogen and natural gas fuel for transport all over the country.

Gasrec with around twenty biomethane fuelling points around the country, seem well-placed to supply the biomethane in bio-LNG or bio-CNG  form.

Could Gasrec Deliver Hydrogen?

Various bus companies in the UK, have had difficulty getting the fuel for their hydrogen buses.

I believe that delivering hydrogen would be very similar to delivering LNG and if Gasrec can deliver LNG successfully and safely, they probably have the technology to do the same for hydrogen.

Centrica Seem To Be Assembling An Interesting Consortium

These are some deals, that I have reported on this blog, that involve Centrica.

Note.

  1. A lot of these deals are are about hydrogen production.
  2. Some of these deals are about biomethane production.
  3. None of these deals talk about getting hydrogen and biomethane to customers.

It appears to me, that Gasrec have a model that works to get hydrogen, methane and biomethane from production and storage to the end customers.

Developing A Rural Hydrogen Network

In Developing A Rural Hydrogen Network, I talked about supplying all those millions of off-gas grid properties with hydrogen for heating, agricultural and industrial purposes, in the countryside of the UK.

Gasrec have the technology to decarbonise the countryside.

Conclusion

Gasrec would appear to be a very useful partner for Centrica.
