Investment in Grain LNG
The title of this post, is the same as that of this press release from Centrica.
This sub-heading outlines the deal.
Centrica plc (the “Company”, “Centrica”) is pleased to announce the acquisition of the Isle of Grain liquified natural gas terminal (“Grain LNG”) in partnership1 with Energy Capital Partners LLP (“ECP”) from National Grid group (“National Grid”) for an enterprise value of £1.5 billion. After taking into account approximately £1.1 billion of new non-recourse project finance debt, Centrica’s 50% share of the equity investment is approximately £200 million.
The press release lists these key points.
- Grain LNG delivers vital energy security for the UK, providing critical LNG import/export, regasification and rapid response gas storage capacity to balance the energy system.
- Aligned with Centrica’s strategy of investing in regulated and contracted assets supporting the energy transition, delivering predictable long-term, inflation-linked cash flows, with 100% of capacity contracted until 2029, >70% until 2038 and >50% until 2045.
- Opportunities for efficiencies to create additional near-term value, and future development options including a combined heat and power plant, bunkering, hydrogen and ammonia.
- Highly efficient funding structure, with Centrica’s equity investment of approximately £200 million alongside non-recourse project financing.
- Strong life of asset returns aligned with Centrica’s financial framework, with an expected unlevered IRR2 of around 9% and an equity IRR2 of around 14%+
Underpins delivery of £1.6 billion end-2028 EBITDA target3 – Centrica’s share of EBITDA expected to be approximately £100 million per annum and cash distributions expected to be around £20 million on average per annum for 2026-2028, representing an attractive yield on Centrica’s equity investment - Partnership with ECP (part of Bridgepoint Group plc), one of the largest private owners of natural gas generation and infrastructure assets in the U.S. with direct experience in supporting grid reliability.
This Google Map shows the various energy assets on the Isle of Grain.
Note.
- It appears that works for the 1, 400 MW NeuConnect interconnector to Wilhelmshaven in Germany, are taking place in the North-East corner of the map.
- Grain CHP powerstation is a 1,275MW CCGT power station, which is owned by German company; Uniper, that is in the South-East corner of the map, which can also supply up to 340MW of heat energy recovered from the steam condensation to run the vapourisers in the nearby liquefied natural gas terminal.
- The Grain LNG terminal is at the Western side of the map.
- In the Thames Estuary to the East of the Isle of Grain, I estimate that there are about 1,500 MW of wind turbines.
I find it interesting that two of the assets are German owned.
I have some thoughts.
It Is A Large Site With Space For Expansion
This Google Map shows the whole of the Isle of Grain.
Note.
- The Grain LNG terminal is around the label Wallend.
- The River Medway runs East-West at the bottom of the map.
- Gas tankers deliver and take on gas at jetties on the North Bank of the Medway.
There could be space to expand the terminal, if the RSPB would allow it.
As an example, I asked Google AI, if peregrine falcons nest on chemical plants and got this reply.
Yes, peregrine falcons do nest on chemical plants. They have adapted to using various urban and industrial structures, including chemical plants, for nesting. This is particularly true in areas where natural cliff habitats are scarce.
Peregrine falcons are known for their adaptability, and their population has seen a resurgence in recent decades, partly due to their ability to utilize man-made structures. These structures often mimic their natural cliffside nesting
Cliffs do seem scarce on the Isle of Grain. I also asked Google AI, if peregrine falcons ate small rodents, as several chemical and other plants, where I’ve worked, had a rodent problem. One plant had a cat problem, as there had been so many rats. This was the reply.
Yes, peregrine falcons do eat small rodents, though they primarily consume birds. While their diet mainly consists of other birds like pigeons, doves, and waterfowl, they will also hunt and eat small mammals, including rodents such as mice, rats, and voles. They are opportunistic hunters and will take advantage of readily available prey, including insects, amphibians, and even fish.
I’m sure if Centrica wanted to expand, they’d employ the best experts.
Who Are ECP?
One of the key points of the press release is that this deal is a partnership with ECP (part of Bridgepoint Group plc), one of the largest private owners of natural gas generation and infrastructure assets in the U.S. with direct experience in supporting grid reliability.
The Wikipedia entry for ECP or Energy Capital Partners has this first section.
Energy Capital Partners Management, LP (ECP) is an American investment firm headquartered in Summit, New Jersey. It focuses on investments in the energy sector. The firm has additional offices in New York City, Houston, San Diego, Fort Lauderdale and Seoul.
In August 2024, ECP merged with Bridgepoint Group to form a private assets investment platform.
The Wikipedia entry for the Bridgepoint Group has this first paragraph.
Bridgepoint Group plc is a British private investment company listed on the London Stock Exchange and is a constituent of the FTSE 250 Index.
The company had started as part of NatWest.
Are The Germans Going To Take Away Some Of Our Electricity?
Consider.
- Germany has a big need to replace Russian gas and indigenous coal, and to decarbonise.
- Neuconnect is a 1.4 GW interconnector between the Isle of Grain and Wilhelmshaven in Germany. It is scheduled to be completed in 2028.
- The Grain CHP powerstation is a 1,275MW CCGT power station, which is owned by German company; Uniper, could almost keep NeuConnect working at full power on its own.
- I said earlier, in the Thames Estuary to the East of the Isle of Grain, I estimate that there are about 1,500 MW of wind turbines. One of which is part German-owned.
The Germans are also building a large electrolyser at Wilhelshaven, which is described by Google AI like this.
The Wilhelmshaven Green Energy Hub will initially feature a 500MW electrolyzer, with plans to potentially expand to 1GW, according to Energy Monitor. The hub, a joint project between Tree Energy Solutions (TES) and EWE, aims to produce green hydrogen using renewable energy sources like offshore wind. The 500MW electrolyzer is scheduled to be operational by 2028.
I wouldn’t be surprised to see that the Wilhelmshaven electrolyser were to be powered by British-generated electricity flowing down NeuConnect.
Centrica Says Their Future Development Options Include A Combined Heat And Power Plant
This objective was set in one of the key points.
This is the first paragraph of the Wikipedia entry for the Grain LNG Terminal.
Grain LNG Terminal is a Liquefied Natural Gas (LNG) terminal on the Isle of Grain, 37 miles (60 km) east of London. It has facilities for the offloading and reloading of LNG from ships at two jetties on the River Medway; for storing and blending LNG; for truck loading; and regasifying and blending natural gas to meet UK specifications. The terminal can handle up to 15 million tonnes per annum of LNG, has a storage capacity for one million cubic metres of LNG, and is able to regasify up to 645 GWh per day (58 million cubic metres per day) for delivery into the high pressure gas National Transmission System (NTS). The facility is owned and operated by National Grid Grain LNG Ltd, a wholly owned subsidiary of National Grid.
Note.
- This paragraph was written before the Centrica takeover.
- The terminal also converts liquid natural gas into gas to be distributed around the UK.
The heat needed to convert the liquid natural gas to gas is provided by the Grain CHP power station.
- Currently 340 MW of heat is provided.
- If the Grain LNG terminal is expanded, it will probably need more heat.
I can see Centrica building a combined heat and power (CHP) power station, that can be expanded to meet the current and future needs of gasification at the Grain LNG terminal.
I wouldn’t be surprised to see the CHP power station fitted with carbon capture, as Kent is surely one county, where carbon dioxide can be used in food production, so we can generate our carbon dioxide and eat it.
Centrica Says Their Future Development Options Include Hydrogen
This objective was set in one of the key points.
Consider.
- Centrica are an investor in HiiROC, who have a unique method of generating affordable zero-carbon hydrogen called thermal plasma electrolysis, which uses a fifth of the electricity, that traditional electrolysis does.
- HiiROC can use natural gas as a feedstock. Centrica won’t be short of that at Grain.
- There is space to build a large HiiROC system at the Isle of Grain site.
- The hydrogen could be taken away by tanker ships.
Like the electricity , which will use the 450 mile NeuConnect interconnector, the hydrogen could even be exported to Wilhelmshaven in Germany by pipeline.
Wilhelmshaven is being setup to be a major German hub to both generate, import and distribute hydrogen.
I asked Google AI, how much hydrogen a GWh would produce and received this answer.
A GWh of electricity can produce approximately 20-22 tonnes of hydrogen through electrolysis, depending on the efficiency of the electrolyzer. Modern commercial electrolyzers operate at an efficiency of roughly 70-80%, meaning they require about 50-55 kWh of electricity to produce 1 kg of hydrogen. A GWh (1 gigawatt-hour) is equal to 1,000,000 kWh, and 1 tonne of hydrogen contains roughly 33.33 MWh of energy.
As it is claimed on the web that HiiROC is five times more efficient than traditional electrolysis, it could need around 10-11 kWh to produce one kg. of hydrogen.
1 GWh would produce between 90-100 tonnes of hydrogen.
Centrica Says Their Future Development Options Include Ammonia
This objective was set in one of the key points.
I asked Google AI if ammonia can be produced from hydrogen and received this answer.
Yes, ammonia (NH3) can be produced from hydrogen (H2) through a process called the Haber-Bosch process. This process involves combining hydrogen with nitrogen (N2) from the air, under high temperature and pressure, in the presence of a catalyst.
Ammonia has a large number of uses, including making fertiliser and the powering of large ships.
I asked Google AI, if there are small Haber-Bosch processes to make ammonia from hydrogen and nitrogen and received this answer.
Yes, there are efforts to develop smaller-scale Haber-Bosch processes for ammonia production. While the traditional Haber-Bosch process is typically associated with large industrial plants, research and development are exploring ways to adapt it for smaller, distributed production, particularly for localized fertilizer or fuel applications.
I wondered if Centrica are involved in the efforts to develop smaller-scale Haber-Bosch processes for ammonia production.
Google AI gave me this quick answer.
Centrica is involved in research related to the Haber-Bosch process, particularly in the context of transitioning to a low-carbon energy future. They are exploring how to adapt the Haber-Bosch process, which is crucial for fertilizer production but also a significant source of CO2 emissions, to utilize renewable energy sources. This includes investigating the use of green hydrogen produced from water electrolysis and renewable electricity. Centrica is also involved in research related to using ammonia as a fuel, including potentially for power generation
That looks to be a very positive answer. Especially, as local low-carbon fertiliser production could be a very powerful concept.
Centrica Says Their Future Development Options Include Bunkering
This objective was set in one of the key points.
Bunkering is the process of refuelling ships.
I didn’t know much about bunkering, when I started to read Centrica’s press release, but the Wikipedia entry, was a good way to get some information.
This section in the Wikipedia entry is entitled Two Types Of Bunkering, where this is said.
The two most common types of bunkering procedure at sea are “ship to ship bunkering” (STSB), in which one ship acts as a terminal, while the other moors. The second type is “stern line bunkering” (SLB), which is the easiest method of transferring oil but can be risky during bad weather.
Over the years, I have found, that two zero-carbon fuels are under development, for powering ships; hydrogen and ammonia. Others are developing ships powered by naturalo gas.
I asked Google AI if hydrogen can power ships and received this answer.
Yes, hydrogen can power ships. It can be used as a fuel for fuel cells, which generate electricity to power the ship’s propulsion and other systems, or it can be burned in modified combustion engines. Hydrogen offers a zero-emission solution for shipping, with water vapor being the only byproduct when used in fuel cells.
Google AI also told me this.
The world’s first hydrogen-powered cruise ship, the “Viking Libra”, is currently under construction and is scheduled for delivery in late 2026. This innovative vessel, a collaboration between Viking Cruises and Italian shipbuilder Fincantieri, will utilize hydrogen for both propulsion and electricity generation, aiming for zero-emission operation.
I also asked Google AI if ammonia can power ships and received this answer.
Yes, ammonia can be used to power ships and is considered a promising alternative fuel for the maritime industry. Several companies and organizations are actively developing ammonia-powered ship designs and technologies. While challenges remain, particularly around safety and infrastructure, ammonia is seen as a key potential fuel for decarbonizing shipping.
Finally, I asked I asked Google AI if natural gas can power ships and received this answer.
Yes, ships can be powered by natural gas, specifically in the form of liquefied natural gas (LNG). LNG is increasingly used as a marine fuel, offering environmental benefits over traditional fuels like diesel.
It would seem to be a case of you pays your money and makes a choice between one of four technologies; ammonia, hydrogen fuel-cell, hydrogen-ICE and LNG.
I looks to me, that if Centrica provide bunkering services for ships, they have the means to cover most of the market by providing hydrogen and ammonia, in addition to natural gas.
Although, I don’t know much about bunkering, I do feel that the two current methods, that work for oil, could be made to work for these fuels.
This Google Map shows the Thames Estuary.
Note.
- The Port of Tilbury is in the South-West corner of the map.
- London Gateway is indicated by the red arrow.
- The Isle of Grain is in the South-East corner of the map.
- Other ports between Tilbury and the Isle of Grain include Barking, Dagenham, Dartford, Erith, Greenwich, Northfleet, Purfleet, Silvertown and Thurrock.
There was never a more true phrase than – “Location, Location and Location”. And the Isle of Grain would appear to be in the right place to send out a bunkering tanker to a passing ship, that was calling at a port in London or just passing through the Strait of Dover.
This Google Map shows the Thames between London Gateway and the Isle of Grain.
Note.
- London Gateway is indicated by the red arrow.
- The Isle of Grain is in the South-East corner of the map.
It seems to me, that a refuelling philosophy could easily be worked out.
How Large is The Bunkering Market?
I asked Google AI this question and received this answer.
The world bunker fuel market is a multi-billion dollar industry, with the market size valued at USD 150.93 billion in 2023. It is projected to reach USD 242.29 billion by 2032, growing at a CAGR of 5.4% according to SkyQuest Technology. In terms of volume, the global bunker demand was estimated at 233.1 million metric tons in 2023 according to the IMO.
The market is not small!
Demonstration Of Commercial-Size Hydrogen Module
The title of this post, is the same as that of news item on the SunHydrogen web site.
This is the sub-heading.
SunHydrogen has successfully demonstrated live operation of its commercial-size 1.92m² hydrogen module, producing renewable hydrogen using only sunlight and water. This major milestone showcases the scalability and off-grid potential of the company’s renewable hydrogen production technology.
These first three paragraphs add more details.
SunHydrogen, developer of a breakthrough technology to produce renewable hydrogen using sunlight and water, today announced the successful live operation of its 1.92 m² (20.7 sq. ft.) hydrogen module. Conducted in an open prototype housing, the demonstration marks a pivotal milestone in the company’s path toward commercial-scale, renewable hydrogen production.
The 1.92m² hydrogen module, which uses only sunlight and water to produce hydrogen, represents the most advanced version of SunHydrogen’s proprietary hydrogen production technology. Engineered to operate independent of the electrical grid, the system integrates solar collection and hydrogen production into a single unit, offering a modular and scalable solution for distributed renewable hydrogen.
“This successful demonstration of the commercial-size reactor underscores the progress we’ve made in bringing our technology out of the lab and into the real world,” said Tim Young, CEO of SunHydrogen.
There is a video of this demonstration.
On their home page, there is a section called A Breakthrough In Clean Energy, where this is said.
SunHydrogen has developed a breakthrough technology to produce renewable hydrogen using sunlight and any source of water.
By optimizing the science of water electrolysis at the nano-level, our low-cost photoelectrochemical technology uses sunlight to separate hydrogen from water, making the process truly green from start to finish.
I will accept their word that it is truly green, but it is truly unique in that it doesn’t appear to use only sunlight to generate hydrogen.
Hydrogen Deployment Milestone For Cemex And HiiROC
The title of this post, is the same as that of this article on Agg-Net.
This is the sub-heading.
Cemex kick-start first-of-a-kind low-carbon hydrogen project using thermal plasma electrolysis in cement production
These first two paragraphs add more detail.
CEMEX Ventures, Cemex’s corporate venture capital (CVC) and open innovation unit, announced today an initial hydrogen deployment at industrial scale with HiiROC, the pioneering British hydrogen company that produces affordable, clean hydrogen, at their Rugby cement plant in the UK.
Hydrogen has emerged as a low-carbon energy source within the construction industry’s decarbonization roadmap and offers potential as an energy solution to help reduce the sector’s reliance on fossil fuels and lower CO2 emissions. This venture marks a significant milestone for Cemex, as it represents the beginning of a large-scale strategic project plan with the aim to further lower their carbon emissions in cement production.
These third paragraph is a good outline of HiiROC and how it can be deployed.
HiiROC produce carbon-neutral hydrogen using their proprietary Thermal Plasma Electrolysis (TPE) process, which requires just one-fifth of the electrical energy used in water electrolysis and captures carbon as a solid by-product, avoiding CO2 emissions – a game-changer for the industry. HiiROC’s modular solution can be deployed as single units to full-scale industrial plants, and the hydrogen produced can be used as an alternative energy source to fuel clinker production processes, helping Cemex to achieve their decarbonization goals.
Centrica, Cemex, Hyundai, Kia and others are investors in HiiROC.
I asked Google AI, what percentage of carbon emissions came from cement production and got this answer.
Cement production accounts for roughly 8% of global carbon dioxide (CO2) emissions, according to think tank Chatham House. This makes it a significant contributor to climate change, with the industry’s emissions comparable to the total emissions of some countries.
If HiiROC can take a big bite out of carbon emissions, by reducing cement production’s 8 % share, they would be on a winner.
An Interesting Comment From Lord Peter Hendy
This article on Modern Railways is entitled Chiltern FINALLY Signs Mk 5 Deal.
This extract from the article describes the deal.
An agreement for Chiltern Railways to lease the Mk 5A coaches previously operated by TransPennine Express and owned by Beacon Rail Leasing has been signed – and the trains are due to replace the current Mk 3 stock in phases from 2026. A 10-year lease has been agreed for the vehicles.
Chiltern will take on all 13 five-car sets as well as the spare Driving Trailer and the dedicated pool of 14 Class 68 locomotives.
The article also, has this excellent quote from Lord Peter Hendy, who is the Rail Minister at the end.
This government is putting passengers back at the heart of the 21st century railway by investing to make journeys easier, greener, and more comfortable.
“We are continuing to support Chiltern as they develop a plan to introduce additional services into their timetable, giving people more opportunities to work, live, and socialise.
I agree with much of what Lord Peter Hendy says, but could we see some actions to back up the words.
I have a few thoughts.
Lumo To Glasgow
I wrote about this new service in Lumo Will Extend Its King’s Cross And Edinburgh Service To Glasgow.
Given the opposition of the Transport Minister to open access services, I didn’t think this innovative service would be approved.
- But it does add an affordable passenger-friendly service to London and Glasgow routes.
- It will certainly be an easier route to London for some in Scotland.
- It also adds some much-needed direct services between Newcastle and Glasgow.
Did Lord Peter Hendy have words to help Lumo get its approval?
As I wrote in Could London And Central Scotland Air Passengers Be Persuaded To Use The Trains?, I also believe that this new Lumo service could persuade more air passengers to take the train to Scotland.
Lumo To Stirling
I wrote about this service in ORR: Open Access Services Given Green Light Between London And Stirling.
- First Group has taken over Grand Union Trains and the service will now be run by Lumo, who will use diesel Class 222 trains.
- But Lumo will have the option of running their electric Class 803 trains on the route, as it is fully electrified, when their fleet receives more trains.
This was another service, that I didn’t think would be approved, as no other services on the West Coast Main Line were approved, as Network Rail objected.
But it certainly meets the words in Lord Peter Hendy’s statement.
Like Lumo’s service to Glasgow, when the Stirling service gets electric trains, it will surely cut carbon emissions of travellers to Central Scotland.
Chiltern’s Replacement Trains
Chiltern Railways are replacing this fleet of locomotive hauled trains.
- 8 Class 68 locomotives
- 25 Mark 3 coaches
- 6 Driving Van Trailers
As services between London Marylebone and Birmingham Moor Street stations consist of one locomotive, five coaches and one driving van trailer, that means there are two spare locomotives, one spare coach and one spare driving van trailer, if there are five rakes of coaches in service.
The new fleet will be.
- 14 Class 68 locomotives
- 52 Mark 5A coaches
- 14 Driving Van Trailers
If services between London Marylebone and Birmingham Moor Street stations consist of one locomotive, four coaches and one driving van trailer, that means there are one spare locomotive and one spare driving van trailer, which gives a possible thirteen rakes of coaches in service.
There are certainly enough to expand Chiltern’s services. The obvious destination would surely be Oxford. These pictures show the two North-pacing platforms at Oxford station.
The platforms would be shared with East-West Rail, but they are around 160 metres in length.
The Modern Railways article quote Arriva Group Managing Director UK Trains Amanda Furlong as saying this.
Upgrading our fleet is a vital next step in Chiltern’s modernisation plans and an important part of Arriva’s wider ambition to support the transition to more sustainable rail travel across the UK and Europe.
We are proud to support this important milestone for Chiltern Railways, which is a great example of what can be achieved through strong collaboration with Government to deliver practical improvements for passengers. We look forward to seeing these upgraded trains improve journeys and lower emissions across the network.
She certainly would agree on some issues with Lord Peter Hendy.
So will Chiltern Railways do something to reduce the carbon footprint of their fourteen Class 68 locomotives?
- The Class 68 locomotives don’t have too many miles on the clock.
- Chiltern have already run some their Class 68 locomotives on HVO, so this must be a possibility.
- In total there are thirty-four Class 68 locomotives in service all of which have Caterpillar engines, so a conversion to zero-carbon power could be worthwhile.
I asked Google for an AI Overview on How many diesel locomotives have caterpillar engines worldwide? I got this answer.
While a precise worldwide count of diesel locomotives powered by Caterpillar (CAT) engines is difficult to pinpoint, it’s estimated that hundreds, if not thousands, of locomotives are equipped with CAT engines. Caterpillar has a long history of supplying engines to the rail industry, with engines like the 3500 series powering both mainline and switcher locomotives. Additionally, CAT engines are also used in generator sets for Head End Power (HEP) in passenger locomotives.
Note.
- It appears that, Caterpillar might have given up making truck engines because of emission issues.
- London Marylebone and Oxford is 66.8 miles
- London Marylebone and Birmingham Snow Hill is 112.3 miles.
Perhaps one of the consultants like Ricardo could convert these locomotives to run on hydrogen.
Council Invests £16m In Hydrogen Buses
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
There are now 34 hydrogen buses on the streets of Surrey, the council has announced.
These two paragraphs add more details.
Surrey County Council (SCC) said it has invested £16m and partnered with Metrobus to provide greener commuting options.
The fleet is now made up of 23 single-deck buses and 11 double-deckers, the council said.
I wrote about a ride on one of these buses to Gatwick Airport in Sutton Station To Gatwick Airport By Hydrogen-Powered Bus.
From the comments in the article, by a Surrey County Council councillor, the council seems very pleased with their hydrogen buses.
Singapore’s First Hydrogen-Powered Data Center Launched By DayOne Using SOFC Technology
The title of this post, is the same as that of this article on Fuel Cell Works.
These two bullet points act as sub-headings.
- DayOne has broken ground on its first AI-ready hyperscale data center in Singapore, a 20MW facility set to be operational in 2026. The project integrates 100% renewable energy, SOFC-based hydrogen power generation, and cutting-edge hybrid cooling technologies.
- Strategic partnerships with Sembcorp and NUS will drive green energy adoption and R&D in sustainable tropical data center innovation, aligning with Singapore’s AI and digital infrastructure goals.
This data centre and the companies and the technologies behind it, are certainly ones to watch.
The R & D and innovation behind it could allow data centres to be built in more tropical places than is currently possible.
British Gas Owner Mulls Mini-Nuke Challenge To Rolls-Royce
The title of this post, is the same as that of this article in The Telegraph.
This is the sub-heading.
Centrica is looking to follow Rolls-Royce in developing small modular reactors
These are the first three paragraphs.
The owner of British Gas is considering investing in mini nuclear power plants in the UK as it seeks to cash in on burgeoning demand for the technology.
Centrica is in early talks with the Government about a potential future deal that could see the energy giant participate in the development of so-called small modular reactors (SMRs).
It comes after Ed Miliband, the Energy Secretary, last month announced billions of pounds in funding for SMRs, which will form part of a new “golden age” for atomic energy.
In Centrica Really Can’t Lose At Sizewell, I looked at Centrica’s involvement in Sizewell C and in particular the financing of the nuke and what Centrica would do with their share of the electricity, that the nuke will produce.
I listed these uses for hydrogen in the East of England.
- Transport – Buses, Coaches and Trucks
- Large Construction Projects
- Rail
- Ports
- Airports
- Agriculture And The Rural Economy
- Exports
I do wonder, if Centrica made the investment in Sizewell C, when they realised that there were a lot of uses for hydrogen and producing hydrogen using the electricity from a nuclear power station was a good way to generate hydrogen.
- Sizewell B is a 1.2 GW nuclear powerstation.
- Sizewell C is a 3.2 GW nuclear powerstation.
- Their investment in HiiROC surely gives them access to the technology to generate hydrogen.
- Centrica have a lot of experience of selling natural gas to customers, who need energy.
- There were also substantial government guarantees involved.
- Hydrogen made by a nuclear reaxtor is generally referred to as pink hydrogen.
- In Westinghouse And Bloom Energy To Team Up For Pink Hydrogen, I describe how two American companies have formed a partnership to make pink hydrogen.
Before they invested in Sizewell C, they would have done detailed financial and technical due diligence.
Did Centrica then scale the calculations to see if funding a Small Modular Reactor (SMR) to make hydrogen was a viable deal?
- SMRs are typically around 400-500 MW.
- The article mentions Rolls-Royce, but other companies are developing SMRs.
- Centrica use Rolls-Royce mtu generators for some of their installations.
- Some SMR/HiiROC systems could be built close to steelworks or other high energy users.
This is a very interesting development in taking the UK to net-zero.
Centrica Really Can’t Lose At Sizewell
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Centrica’s £1.3 billion investment in Sizewell C guarantees substantial returns, even with cost overruns.
These two-and-a-half paragraphs explain the funding.
Now we know what Ed Miliband means by his “golden age of nuclear” — golden for the companies putting their money into Sizewell C. Yes, reactor projects have a habit of blowing up private investors. But maybe not this one. It looks more like an exercise in transferring risk to consumers and the taxpayer.
Sure, nobody builds a £38 billion nuke on a Suffolk flood plain without a frisson of danger. But the energy secretary and his Treasury chums have done their bit to make things as safe as possible for the companies putting in equity alongside the government’s 44.9 per cent stake: Canada’s La Caisse with 20 per cent, British Gas-owner Centrica (15 per cent), France’s EDF (12.5 per cent) and Amber Infrastructure (7.6 per cent).
For starters, nearly all the debt for the 3.2 gigawatt plant, three-quarters funded by loans, is coming from the state-backed National Wealth Fund. It’s bunging in up to £36.6 billion, with £5 billion more guaranteed by a French export credit agency.
It looks to me that between them the British and French governments are providing £41.5 billion of loans to build the £38 billion nuke.
These are my thoughts.
Hydrogen And Sizewell C
This page on the Sizewell C web site is entitled Hydrogen And Sizewell C.
Under a heading of Hydrogen Buses, this is said.
At Sizewell C, we are exploring how we can produce and use hydrogen in several ways. We are working with Wrightbus on a pilot scheme which, if successful, could see thousands of workers transported to and from site on hydrogen double decker buses. You can read more about the pilot scheme in our press release
Firstly, it could help lower emissions during construction of the power station. Secondly, once Sizewell C is operational, we hope to use some of the heat it generates (alongside electricity) to make hydrogen more efficiently.
This would appear to be a more general statement about hydrogen and that the following is planned.
- Hydrogen-powered buses will be used to bring workers to the site. A press release on the Sizewell C web site, talks about up to 150 buses. That would probably be enough buses for all of Suffolk.
- Hydrogen-powered construction equipment will be used in the building of the power station.
- It also talks about using the excess heat from the power station to make hydrogen more efficiently. I talk about this process in Westinghouse And Bloom Energy To Team Up For Pink Hydrogen.
This is a substantial investment in hydrogen.
Centrica And Electricity From Sizewell C
The article in The Times, also says this.
Even so, there’s a fair bit of protection for the likes of Centrica, which has also agreed a 20-year offtake deal for its share of Sizewell’s electricity. The price of that is not yet known.
Nothing is said in the article about the size of Centrica’s electricity offtake.
- If they get 15 % of Sizewell C, that would by 480 MW.
- If they get 15 % of Sizewell B + C, that would by 660 MW.
If they use their share to generate hydrogen, Suffolk would have a massive hydrogen hub.
To power the buses and construction of Sizewell C, Sizewell B could be used to provide electricity to create the hydrogen.
How Would The Hydrogen Be Produced?
Centrica, along with other companies, who include Hyundai and Kia, are backers of a company in Hull called HiiROC, who use a process called Thermal Plasma Electrolysis to generate hydrogen.
On their web site, they have this sub-heading.
A Transformational New Process For Affordable Clean Hydrogen
The web site also describes the process as scalable from small modular units up to industrial scale. It also says this about the costs of the system: As cheap as SMR without needing CCUS; a fraction of the energy/cost of water electrolysis.
If HiiROC have achieved their objective of scalability, then Centrica could grow their electrolyser to meet demand.
How Would The Hydrogen Be Distributed?
Consider.
- Currently, the Sizewell site has both road and rail access.
- I can still see in my mind from the 1960s, ICI’s specialist articulated Foden trucks lined up in the yard at Runcorn, taking on their cargoes of hydrogen for delivery all over the country.
- As that factory is still producing hydrogen and I can’t remember any accidents in the last sixty years, I am fairly sure that a range of suitable hydrogen trucks could be developed to deliver hydrogen by road.
- The road network to the Siewell site is being updated to ensure smooth delivery of workers and materials.
- The rail access to the Sizewell site is also being improved, for the delivery of bulk materials.
I believe there will be no problems delivering hydrogen from the Sizewell site.
I also believe that there could be scope for a special-purpose self-propelled hydrogen tanker train, which could both distribute and supply the hydrogen to the vehicles, locomotives and equipment that will be using it.
Where Will The Hydrogen Be Used?
I have lived a large part of my life in Suffolk and know the county well.
In my childhood, there was quite a lot of heavy industry, but now that has all gone and employment is based on agriculture, the Port of Felixstowe and service industries.
I can see hydrogen being used in the following industries.
Transport
Buses and heavy trucks would be powered by hydrogen.
The ports in the East of England support a large number of heavy trucks.
Large Construction Projects
Sizewell C is not the only large construction project in the East of England, that is aiming to use low-carbon construction involving hydrogen. In Gallagher Group Host Hydrogen Fuel Trial At Hermitage Quarry, I talked about a hydrogen fuel trial for the Lower Thames Crossing, that involved JCB and Ryse Hydrogen.
Hydrogen for the Lower Thames Crossing could be delivered from Sizewell by truck, down the A12.
Rail
We may not ever see hydrogen-powered passenger trains in this country, but I do believe that we could see hydrogen-powered freight locomotives.
Consider.
- The latest electro-diesel Class 99 locomotives from Stadler have a Cummins diesel engine.
- The diesel engine is used, when there is no electrification.
- Cummins have developed the technology, that allows them to convert their latest diesel engines to hydrogen or natural gas power, by changing the cylinder head and the fuel system.
- Access to the Port of Felixstowe and London Gateway needs a locomotive with a self-powered capability for the last few miles of the route.
A Class 99 locomotive converted to hydrogen would be able to run with out emitting any carbon dioxide from Felixstowe or London Gateway to Glasgow or Edinburgh.
Ports
Ports have three main uses for hydrogen.
- To power ground-handing equipment, to create a pollution-free atmosphere for port workers.
- To fuel ships of all sizes from the humblest work-boat to the largest container ships.
- There may need to be fuel for hydrogen-powered rail locomotives in the future.
There are seven ports with excellent road and/or rail connections to the Sizewell site; Felixstowe, Great Yarmouth, Harwich, Ipswich, London Gateway, Lowestoft and Tilbury.
The proposed Freeport East is also developing their own green hydrogen hub, which is described on this page on the Freeport East web site.
Airports
Airports have two main uses for hydrogen.
- To power ground-handing equipment, to create a pollution-free atmosphere for airport workers.
- In the future, there is likely to be hydrogen-powered aircraft.
There are three airports with excellent road and/or rail connections to the Sizewell site; Norwich, Southend and Stansted.
Agriculture And The Rural Economy
Agriculture and the rural economy would be difficult to decarbonise.
Consider.
- Currently, most farms would use diesel power for tractors and agricultural equipment, which is delivered by truck.
- Many rural properties are heated by propane or fuel oil, which is delivered by truck.
- Some high-energy rural businesses like blacksmiths rely on propane, which is delivered by truck.
- Electrification could be possible for some applications, but ploughing the heavy land of Suffolk, with the added weight of a battery on the tractor, would probably be a mathematical impossibility.
- JCB are developing hydrogen-powered construction equipment and already make tractors.
- Hydrogen could be delivered by truck to farms and rural properties.
- Many boilers can be converted from propoane to run on hydrogen.
I feel, that hydrogen could be the ideal fuel to decarbonise agriculture and the rural economy.
I cover this application in detail in Developing A Rural Hydrogen Network.
Exports
Consider.
- Sizewell B and Sizewell C nuclear powerstations have a combined output of 4.4 GW.
- A rough calculation shows that there is a total of 7.2 GW of wind farms planned off the Suffolk coast.
- The East Anglian Array wind farm alone is said in Wikipedia to be planned to expand to 7.2 GW.
- The Sizewell site has a high capacity connection to the National Grid.
Nuclear plus wind should keep the lights on in the East of England.
Any excess electricity could be converted into hydrogen.
This Google Map shows the location of Sizewell B in relation to Belgium, Germany and The Netherlands.
The Sizewell site is indicated by the red arrow.
The offshore oil and gas industry has used technology like single buoy moorings and coastal tankers to collect offshore natural gas for decades.
I don’t see why coastal hydrogen tankers couldn’t export excess hydrogen to places around the North Sea, who need the fuel.
It should be born in mind, that Centrica have a good reputation in doing natural gas trading. This expertise would surely be useful in hydrogen trading.
Conclusion
I believe that a hydrogen hub developed at Sizewell makes sense and I also believe that Centrica have the skills and technology to make it work.
One Of The Five Large Buses Sold In Korea This Year Is Hydrogen-Powered
The title of this post, is the same as that of this article in Pulse.
These are the first three paragraphs.
Nearly one in five large buses sold in South Korea in 2025 to date has been a hydrogen fuel cell electric vehicle (FCEV). In response, Hyundai Motor Co. is increasingly focusing on hydrogen-powered commercial transport amid sluggish demand for hydrogen-powered passenger cars.
According to data from the Korea Automobile & Mobility Association (KAMA) and Hyundai Motor, 380 hydrogen-powered buses were sold in the first five months of 2025, out of 1,923 large buses sold overall. The market share stood at 19.8 percent, indicating a significant increase from 6 percent in 2023 and 14.4 percent the previous year.
Analysts say hydrogen power is better suited for commercial vehicles than for passenger cars. While electric vehicles work well for lighter, smaller vehicles, hydrogen-powered systems offer key advantages for larger vehicles, including longer range, shorter refueling times, and greater payload capacity.
Korea and Germany certainly have more hydrogen-powered buses than the UK.
But then we are rather lagging behind other countries in the use of hydrogen. I am certainly writing fewer hydrogen stories since the change of government.
The Hindenberg has done a wonderful job, in convincing politicians that hydrogen is dangerous.
