Could Centrica Build An Alternative Grid For The UK?
Andy Burnham’s Speech In Liverpool Introduced The Great British Grid
This extract is what he said on energy and the grid.
One of the biggest barriers to growth in the UK is the cost of energy. British businesses and billpayers pay some of the highest energy costs in Europe.
Within 10 years, I want those costs to be in line with our neighbours.
This means reforming a broken energy market so it better serves the public interest.
We are already taking more control of our electricity prices with a massive expansion of home-grown renewables and nuclear. I have asked Miatta to speed up the breaking of the link between what we pay for power at home and the international gas market, to get bills down.
And we will be pragmatic in relation to the North Sea as we build a bridge to a clean energy future and face the climate crisis.
But it’s not just the price. The system needs to work better too. You would not believe how many businesses complain to me they can’t get going because they can’t get connected to the grid.
It pushes costs up. It drags growth down. And it holds Britain back. We won’t get the growth and inward investment we need if we don’t fix it.
So, for the first time, we will have a national energy plan and we will bring back local democratic control through a stronger role for mayors and local leaders.
But we must go further. Today I can announce our plan for Great British Grid. A new branch of Great British Energy. A publicly-owned company that will challenge the private sector operators.
But is Andy Burnham’s plan realisable?
The Great Grid Upgrade From Norwich To Tilbury
National Grid are aiming to replace the grid between Norwich and Tilbury to add extra capacity and the details of the project are on this web site.
This is a map of the route.
To ascertain the level of objections, I asked Google AI “Norwich to Tilbury grid objections” and received this reply.
Local councils, residents, and organizations object to National Grid’s Norwich to Tilbury Project primarily due to the visual and ecological damage of using 50-meter overhead pylons instead of offshore or underground alternatives.
Key Objections and Concerns
Overhead Pylons vs. Alternatives: Opposition to roughly 100 miles (159–183 km) of towering onshore overground lines. Objectors demand fully costed offshore high-voltage direct current (HVDC) or underground cabling options.
Environmental & Landscape Harm: Severe impact on protected and valued landscapes, including the Dedham Vale national landscape and Waveney Valley, alongside extensive tree loss and disruption to local wildlife habitats.
Heritage & Property Impacts: Damage to the settings of historic buildings and significant property or land devaluation, including negative impacts on planned developments like the Dunton Hills Garden Village in Brentwood.
Unrealistic Delivery Timeline: Concern that the targeted 2030/2031 completion deadline is overly ambitious, forcing rushed implementation without proper scrutiny of cumulative effects from multiple East Anglian energy projects.
Community Disruption: Strain on local highways, disruptive weekend and bank holiday working hours, agricultural disruption, and a lack of adequate community compensation or tangible social value.
The Nimbys don’t seem very keen on more and bigger overhead power lines.
Conclusion
I believe building a second set of power lines across the country will be very difficult, if not impossible.
The Investment Of Centrica And Others In innovative Energy Technology
I think we’ll see innovation from the likes of Centrica, Octopus, National Grid and others, as to how we get our energy delivered.
Centrica and others, who include the UK Government, have backed four British companies, that I’m sure will be used in the grid of 2030.
- Ceres have developed a fuel cell that runs on hydrogen, biomethane or natural gas. It was thought it would be used to power data centres, but it could be used to provide power anywhere there is a gas supply, like a big factory or a new housing estate.
- Heata was developed by British Gas Research and is part of a data centre, which sits in a domestic hot water tank and the waste heat gives you affordable hot water.
- Highview Power make liquid-air batteries up to 300 MW/3.2 GWh. Significantly, Andy Burnham performed the groundbreaking for a 50 MW/300 MWh battery in Manchester, when he was Mayor of Greater Manchester.
- HiiROC from Hull University have a way to make hydrogen that uses only a fifth of the electricity. Cemex are using HiiROC to make low-carbon cement at Rugby. I also think Jim Ratcliffe has plans for HiiROC, as he is an investor with Centrica and others.
Could Centrica build an innovative Great British Grid from their investments?
I don’t think so because of the problem I indicated earlier with Norwich to Tilbury of putting up more overhead cables.
But all of these four companies can provide support and enhancement to the existing grid.
- Ceres could be used to provide extra power, where it is needed, if there is a suitable gas supply.
- Heata could be used to give a large proportion of houses and flats affordable hot water.
- Highview Power could be used to provide energy storage where too much energy is being generated at times and needs to be stored for a number of hours.
- I believe that many large wind farms will be connected to the grid, with a Highview Power battery at the sub-station.
- I also believe that we could see Highview Power batteries installed offshore to smooth wind farm output.
- HiiROC could produce hydrogen when and where it is needed.
The big problem will be that the grid will get more complicated and will be more difficult to control.
In Centrica And Return Partner To Scale Battery Flexibility In Germany, I ask Google AI if Centrica are good at optimising batteries and received this reply.
Yes, Centrica is considered a strong and established player in grid battery (BESS) optimisation.
Centrica Energy leverages over 15 years of flexible asset trading experience and has actively optimised battery energy storage systems since 2018. They currently manage over 950 MW of grid-scale batteries on contract across the UK and Europe.
It may be difficult to manage all these assets, but it does appear that Centrica have the mathematicians and engineers, who are up to the task.
The Future Of Nuclear
Consider.
- The four nuclear stations at Hartlepool, Heysham 1, Heysham 2 and Torness are to be shut down by March 2030, which will lose approximately 5 GW of zero-carbon electricity.
- Hinckley Point C will deliver 3.2 GW from the early 2030s.
- Sizewell C will deliver 3.2 GW at some time in the future.
Can we rely on solar and wind power to power the UK?
It is not a question of can, but we have to.
But Centrica have made a bold move to link up with X-energy of the US to build a fleet of small modular reactors called an Xe-100.
- I wrote about the initial deal in Centrica And X-energy Agree To Deploy UK’s First Advanced Modular Reactors.
- In Hartlepool Nuclear Reactor Moves To UK Regulatory Assessment, I talk about how the first reactor will be built at Hartlepool.
- In Centrica, X-energy Advance Nuclear Plans As UK Regulators To Begin Design Review For Xe-100, I say more about the design and the parners in the Xe-100.
- In With Federal Funding Windfall, X-energy Advances Small Nuclear Reactor, I talk about US Federal funding for X-energy.
- In TRISO-X Completes Vertical Construction Of TX-1 Fuel Fabrication Facility, I describe how they are cracking on with the fuel facility in the US.
It certainly, seems to be a project that has started with a certain degree of momentum, which says to me, they have got the project management right.
But believe that these 80 MW Xe-100 reactors, if strategically placed around the country will keep us going as older nuclear and gas power stations are retired.
The Relationship Between Andy Burnham And Chris O’Shea
I wrote about this in Have Chris O’Shea And Andy Burnham Met?
I will assume its a good relationship, until proven otherwise.
Conclusion
I wonder whether in the end, the Great British Grid is a series of extensions to the current grid we have.
First Engine Start For First Hydrogen-Powered Locomotive
The title of this post, is the same as that of this article in the Windhoek Observer.
These three paragraphs add more details.
CMB.TECH Namibia’s has said the engine start for Namibia’s first hydrogen-powered locomotive represents an important step in the project’s development.
It is the first hydrogen dual fuel engine to be started in Africa and the first hydrogen dual fuel engine to be started in a locomotive worldwide.
The company revealed that a combined team of eight electrical, mechanical and software engineers, together with the engine commissioning engineer, worked into the night to prepare the locomotive for its first engine start.
These are a few points from the rest of the article.
- During the initial run, the BeHydro engine idled for approximately 30 minutes while the team carried out a series of checks.
- This 2,250-horsepower BeHydro dual fuel engine can operate on both diesel and green hydrogen, with the hydrogen to be produced locally at CMB.TECH Namibia’s facility in Walvis Bay.
- Namibia has a large fleet of idled locomotives that can be repowered with this cost-effective and future proof technology.
I first wrote about the Belgian BeHydro dual fuel engine in Green Tugboats? ‘Revolutionary’ Hydrogen Ship Engine Unveiled In Belgium.
Is History Repeating Itself?
Thirty or forty years ago, I was friendly with a steam locomotive enthusiast called Dick.
- Dick and his mates were helping various African countries, get their steam locomotives running again.
- The Chinese had sold Africa lots of diesel locomotives to replace European steam locomotives, that often dated from before the Second World War.
- But now these Chinese diesels were falling apart.
My friend and his mates were dragging the old steam locomotives out of the sidings and getting them going again.
So with a little help from the Belgians, are the Namibians bringing the ancient Chinese diesel locomotives into the net-zero world of the twenty-first century?
More About The Project
These paragraphs in the Windhoek Observerer describe the project.
- The project is the result of a strategic partnership between three companies firmly rooted in Namibia including TransNamib Holdings Limited, Africa Global Logistics and CMB.TECH Namibia.
- TransNamib is responsible for managing and operating the national rail network and freight services.
- Africa Global Logistics (AGL) is an established logistics operator active in Namibia, playing a key role in freight, transport and logistics operations across the country, with a strong focus on strengthening strategic transport corridors.
- AGL also manages operations at the Walvis Bay Multipurpose Bulk Terminal and operates one of Africa’s largest integrated logistics networks, with a presence in over 50 countries connecting ports, corridors and multimodal supply chains.
- These partners will operate Namibia’s first heavy‑duty freight service running on locally produced green hydrogen.
- Initially, 50 round trips will be covered between the Port of Walvis Bay and the Container Depot near Windhoek during the trial period, with the option to extend operations.
- Green hydrogen for the project will be produced off‑grid at CMB.TECH Namibia’s hydrogen plant in Walvis Bay.
Note.
- It seems very much a Namibian project.
- Namibia has plenty of wind and sun to make the green hydrogen.
- Would they be using an efficient process like HiiROC?
This OpenRailwayMap shows the location of Walvis Bay and Windhoek.
Note.
- Walvis Bay is indicated by the blue arrow.
- Windhoek is East of Walvis Bay, where there is a major railway junction.
- Windhoek and Walvis Bay are about 224 miles apart and a train journey takes between 9 and 11 hours.
It will probably be one of the longest hydrogen-powered rail journeys in the world.
Can The Hiiroc Process Be Used To Make Sustainable Aviation Fuel (SAF)?
After Writing Cemex To Install World-First Hydrogen Process At UK Cement Plant, I just had to ask this question of Google AI and I received this reply.
Yes, the HiiROC process is currently being developed and studied to produce Sustainable Aviation Fuel (SAF).
How the Process Works
Thermal Plasma Electrolysis (TPE): HiiROC’s core technology splits hydrocarbons (like biomethane, natural gas, or flare gas) into clean hydrogen and solid carbon without burning them or emitting carbon dioxide.
Thermal Plasma Reforming (TPR): Building on TPE, this adaptation is being evaluated to create synthetic e-SAF by combining the produced clean hydrogen with carbon dioxide at a lower electricity cost than traditional water electrolysis.
Current Developments
Feasibility Study: HiiROC received grant funding from Scottish Enterprise to study a negative-carbon SAF business in Scotland through its subsidiary Zeleno Ltd and partner Stratus Energy Partners.
Partnerships: The initiative has drawn interest from aviation and energy stakeholders like Airbus, World Kinect, and the Forth Green Freeport to make power-to-liquid SAF more scalable and affordable.
It certainly seems it could be a possible route to SAF.
I should say, that when I worked at ICI at Runcorn, for a period, I had the privilege of sharing an office, with an elderly scientist, who before the Second World War, was closely involved in the development of polythene.
That was a long process, but in the end they got there, mainly because radar needed a top-class insulator for which polythene was the only solution.
Cemex To Install World-First Hydrogen Process At UK Cement Plant
The title of this post, is the same as that of this article on The Chemical Engineer from 2024.
These two paragraphs introduce the article.
CEMEX is set to trial a process developed by Hiiroc that uses plasma to produce hydrogen for greener industrial heat at its cement plant in Rugby, UK.
Cemex is finalising contract details now with UK-based process developer Hiiroc and expects to start engineering studies early next year with hydrogen production set for a “hard deadline” of January 2026. The cement major thinks the process is a better bet for producing hydrogen than water electrolysis because it requires 80% less electricity and wins out over steam methane reforming because it doesn’t produce CO2.
I believe that this process, which has its origins in Hull University, could revolutionise the manufacture of zero-carbon hydrogen.
The article describes its first big application at Cemex’s Rugby cement plant.
There are obviously issues to be solved and the article is mainly an interview with Alfredo Carrato, who is innovation advisor at Cemex Ventures.
These are some thoughts.
HiiROC Is Containerised
The article says this.
Carrato expects the changes required to integrate the process at the Rugby plant to be minimal. One or two of Hiiroc’s containerised process units will be plugged into the grid and pipes installed to carry hydrogen to the existing kiln where a new burner will be installed to combust the hydrogen producing heat to convert limestone to clinker.
It also says this.
If successful, the Rugby plant could see eight or nine of Hiiroc’s modules installed at the site, Carrato said.
There could be a lot of low-carbon cement coming out of Rugby.
But containerisation also means that any factory using natural gas for a lot of heat, can plug in a number of Hiiroc’s containerised process units and decarbonise.
Worldwide Expansion
The article says this.
“We do have plans to expand this across our operations worldwide for a number of reasons. Hydrogen certainly is a relevant vector that we are considering to decarbonise our operations. And second, the modularity of the solution allows for a quick deployment.”
Cemex Aim To Be Net Zero By 2050
The article says this.
Cemex has set itself a target of becoming net zero by 2050. The Hiiroc process can make use of biomethane so could allow Cemex to replace its use of fossil fuel natural gas. It could also use renewable electricity to power its plasma burners. In terms of output, the process produces carbon black which can be used as an additive in its cement-making operations or sold for use in tyres, rubbers, plastics, inks, and toners.
“Because of the stoichiometry, the volume of carbon black is pretty significant, meaning we are not able to take the entirety of what is produced. So, we need to figure out how to also monetise it.”
Hiiroc is searching for alternative markets too. It has partnered with researchers in Europe and the US to investigate how the carbon black from its process could be used in other applications including filters, soil enhancers, and animal feed.
Note.
- The process can run on biomethane, as well as natural gas and chemical plant flare gas.
- The carbon black could be a long-term problem, but I suspect a use will be found.
Having worked in integrated chemical plants, I believe innovative uses for both feedstocks and what to do with the carbon black will be found.
Water Stress
The article says this.
Carrato said: “We’re looking at not only the carbon footprint, but also the stress on water. Water electrolysis has a lot of water demand, whereas technology such as Hiiroc has none. In regions where there’s a lot of water scarcity, we believe that Hiiroc can move the needle [for industrial decarbonisation] way better than water electrolysis.”
Any water problems seem soluble.
Conclusion
Alfredo Carrato of Cemex Ventures seems to be enthusiastic about his charge.
Jim Ratcliffe Mothballs UK Plants Over ‘Ridiculously High Gas Price’
The title of this post, is the same as that of this article in The Times.
These three paragraphs give more details.
Sir Jim Ratcliffe’s Ineos is mothballing three chemical plants in Hull in response to Britain’s “ridiculously high gas price”.
The plants directly employ 245 people producing acetyls, which are used as raw materials for everything from pharmaceuticals to food and military explosives. Ineos said the sites support almost 4,000 jobs in the wider supply chain across Humberside.
Ineos’s Hull acetyls plants “just cannot compete” as gas prices are now 12 times higher in Britain than in the United States, Ratcliffe said. The plants use gas as a feedstock and also burn hydrogen derived from gas as an energy source to power chemical production.
I don’t think, that this story, is as simple as it seems.
Consider.
- Sir Jim Ratcliffe graduated from the University of Birmingham in 1974 with a degree in chemical engineering.
- The plants in Hull make acetyls.
- The acetyl group has a Wikipedia entry.
- From my own experience, the 1970s was an exciting time for chemical engineering.
- ICI were trying to use a process purchased from BASF to make acetylene, which failed miserably, as all the process did was coat Runcorn in soot.
- Did ICI use the acetylene to make acetyls?
- Google AI says you can make acetyl-containing compounds, such as acetic acid and vinyl acetate, starting from acetylene.
- For a time, I shared an office, with a fellow Liverpool University graduate, who was helping to get the ICI plant working.
In the end the ICI plant was dismantled.
Has Sir Jim Ratcliffe A Connection To HiiROC?
I asked Google AI this question and received this reply.
Yes, Sir Jim Ratcliffe has an indirect financial and strategic connection to HiiROC through his petrochemical company, INEOS.
The INEOS Connection: INEOS backed HydrogenOne Capital Growth—a hydrogen-focused investment fund—which made a £10 million equity investment in HiiROC to develop affordable “turquoise hydrogen” (clean hydrogen produced via thermal plasma electrolysis).
Shared Industrial Projects: HiiROC has collaborated on low-carbon hydrogen projects in the Humberside region close to major INEOS operational footprints, connecting clean-tech hydrogen initiatives with heavy UK industrial chemical hubs.
Note.
- The last paragraph, I clipped from The Times mentioned hydrogen.
- The HiiROC process can use any hydrocarbon gas as feedstock and is five times more energy efficient than traditional electrolysis.
- HiiROC is backed technically by the University of Hull.
- The ICI plant produced loads of soot and HiiROC produces carbon black, so I wonder, if the two processes are by any chance related?
It strikes me that some of the various interests have come up with a route to creating acetyls, that is more efficient.
I suspect Sir Jim Ratcliffe will disclose a clever plan at some time.
What Is The Connection Between The University Of Hull And HiiROC?
I asked Google AI this question and received this reply.
The University of Hull and HiiROC have a collaborative partnership focused on developing clean energy technology.
Nature of the ConnectionTechnology
Collaboration: HiiROC worked collaboratively with the University of Hull (leveraging regional programs like those from the university’s Aura Innovation Centre) to help develop and test Thermal Plasma Electrolysis (TPE).
Clean Energy Innovation: This proprietary TPE technology converts biomethane, flare gas, or natural gas into clean “emerald” hydrogen and valuable solid carbon black without greenhouse gas emissions.
By-Product Research: The partnership includes joint efforts to research potential commercial uses for carbon black, the solid carbon by-product created during HiiROC’s hydrogen-generation process.
Regional Growth: HiiROC established its development and testing facilities in Hull to advance this technology, working alongside local academic and business innovation networks tied to the university.
From my experience in the 1960s at ICI Mond Division in Cheshire, I believe that this could be one of the most important research projects in the UK.
Could INEOS Be Going To Collect All Their Flare Gas In Hull?
Consider.
- The HiiROC process can use any hydrocarbon gas as feedstock.
- This would include chemical plant flare gas, biomethane and natural gas.
- The HiiROC process extracts the hydrogen as hydrogen gas.
- The HiiROC process extracts the carbon as carbon black.
I have seven questions.
- Suppose INEOS collected all the flare gas from their chemical plants in Hull, could they use this as feedstock in a HiiROC process to create hydrogen efficiently?
- Could they collect biomethane from Humberside and mix this with the flare gas?
- Could they bring in extra flare gas from chemical plants elsewhere in the UK and Europe using coastal gas tankers or rail tankers?
- Could INEOS use natural gas, if they were short of flare gas and biomethane?
- Could any excess hydrogen be stored in Aldbrough or Rough gas storage?
- Could any excess hydrogen be sold on to other companies?
- Could hydrogen be used to make the acetyls?
I suspect that all questions have an answer in the affirmative.
Conclusion
I feel that Sir Jim Ratcliffe made a very shrewd investment in HiiROC.
Centrica Buys Severn Gas Power Station In South Wales
The title of this post, is the same as that of this article on The Times.
This is the sub-heading.
The owner of British Gas says the plant, acquired from the troubled Calon Energy for £370 million, will help secure supplies during the green transition
These three introductory paragraphs add more details to the story.
The owner of British Gas has acquired the troubled Severn gas power station in south Wales for £370 million after issuing a less than positive future profit guidance.
The combined-cycle gas turbine plant was owned by Calon Energy, which had gone into administration shortly after the start of the pandemic in 2020 when the power station was, for a while, mothballed.
Centrica said it acquired the plant to shore up its energy generation resources and secure electricity supplies during the UK’s green transition.
I think there a lot more to this story, than initially meets the eye.
The Location
The Google Map shows the location of the Severn Power station on the River Usk, to the South of Newport in South Wales.
Note.
- Severn power station is indicated by the red arrow in the South-West of the map.
- The River Usk enters the sea to the West of the site.
- The RSPB Newport Wetlandsare South of the site.
- The long rectangle in the middle of the map is the former Llanwern steelworks, which is now a CAF train factory.
- Newport is also a major station on the main line between London Paddington and Cardiff.
This second Google Map shows the power station site at a larger scale.
I wouldn’t be surprised, that Centrica could fit other equipment on and around the power station site.
- Centrica and/or National Grid might want to put an interconnector across the Severn Estuary.
- There might be a need to connect to wind farms in the Severn Estuary.
- Centrica are building a bunkering facility for ships running on low carbon fuels at Grain LNG Terminal. Will they build one here?
- Centrica could build a HiiROC electrolyser to create hydrogen for difficult to decarbonise industries and bunkering ships.
The site has a lot of potential.
Gas-Fired Power Still Looks A Safe Bet For Centrica In The Renewables Era
I feel rather surprisingly, the title of this post, is the same as this article on the Guardian.
You’d think, that they would be critical of Centrica for keeping the gas power stations going.
But this is the sub-heading.
There will still be a need to have gas in the wings to keep the lights on, so the financials stack up on Severn plant purchase.
So why should Centrica buy a 832 MW closed cycle gas fired power station?
These posts describe, what Centrica have done at Brigg with another closed cycle gas fired power station.
- Construction Under Way To Double Power Station Capacity At Centrica’s Brigg Energy Park
- Hydrogen Milestone: UK’s First Hydrogen-to-Power Trial At Brigg Energy Park
Will Centrica be taking closed cycle gas fired power stations and making them more efficient to provide the back up to wind farms, when wind is having an off day?
I wouldn’t be surprised, if Centrica put a big battery on the two sites, as after all they are a godparent to Highview Power.
Are there any more closed cycle gas fired power stations, that they can acquire?
I asked, Google AI,”How many closed cycle gas fired power stations are there in the uk?” and received this answer.
As of early 2026, there are approximately 35 active combined cycle gas turbine (CCGT) power stations—often referred to as closed-cycle—in the UK.
These plants provide the bulk of the UK’s gas-fired capacity, totaling roughly 30-35 GW along with smaller, single-cycle (OCGT) plants which are used for backup.
Total Capacity: The total capacity of all gas-fired generation (CCGT and others) is approximately 35.7 GW.
Role in Power Mix: CCGTs are highly efficient and provide baseload power, while OCGT plants (about 14+ sites) are typically used for peak demand.
Key Locations: Major plants include Pembroke (RWE), Staythorpe (RWE), Didcot B (RWE), and Connah’s Quay (Uniper).
These plants remain the largest single source of electricity generation on the UK grid, though they are increasingly being paired with carbon capture proposals.
I think, that Engineer Baldrick is now working for Centrica and he has a cunning plan to use efficient CCGT power stations to back up the wind.
Consider.
- Severn power station is an 832 MW combined cycle power plant running on natural gas, which is located near Newport in South Wales.
- 4.5 GW of offshore wind is to be built near Port Talbot.
- Will some hydrogen generated by HiiROC be used to part-fire Severn power station and reduce its carbon footprint.
- South Wales can easily find space for a couple of Highview 300 MW/3.2 GWh CRYOBatteries.
- It would be useful to have a good-sized hydrogen store in South Wales.
That mix would surely provide enough reliable power for green steelmaking and a few data centres.
No Panic At The Pumps … South Koreans Just Stop Driving On Wednesdays
The title of this post, is the same as that of this article on The Times.
This is the sub-heading.
President Lee Jae-myung has urged the public to ‘save every drop of fuel’ and introduced a number-plate rotation to keep drivers off the road
These first three paragraphs deeply illustrate the differences between the energy situation in North and South Korea.
From the lookout point atop Mount Dora, in the heart of the demilitarised zone that has separated the peninsula since 1953, you can clearly see where South Korea ends and North Korea begins.
The trees that proliferate across Korea’s undulating topography come to an abrupt halt. On the land that sits beyond, a farmer can be seen guiding an ox pulling a plough.
Sealed off from the world economy for 73 years, communist North Korea has resorted to cutting down much of its vegetation to burn for fuel. Democratic South Korea, by contrast, has established deep global trading ties that allow the country to import vital natural resources it cannot produce domestically.
North Korean communism certainly can’t be considered green.
I find these two paragraphs extremely significant.
South Korea may have to import almost all of its crude oil, but the country plays a huge role in refining it into petrol, diesel and jet fuel before shipping it around the world. This means that demand from overseas for Korea’s refined products is greater than ever, which has forced the government to step in. The country’s Ministry of Trade, Industry and Energy has implemented mandatory caps on refined petroleum products.
Of all South Korea’s refined products, kerosene, or jet fuel, is the most in demand. The country is one of the biggest exporters of jet fuel in the world. The US, for instance, relies on it for 70 per cent of its total jet fuel imports.
They could also be problematical for the country, as they will surely need to replace these jet fuel exports with exports of sustainable aviation fuel (SAF).
Most viable processes, that I’ve seen need the following ingredients.
- Lots of hydrogen or masses of GWhs of electricity to make it.
- Some carbon atoms, which can even be captured from the air or a gas-fired power station.
- Some form of Fischer-Tropsch process to force the atoms to make sustainable aviation fuel.
There are several companies that can do this, with British ones seeming to often to be connected to Oxford University.
There is also this Anglo-Korean connection over hydrogen.
I asked Google AI, who are investors in innovative hydrogen production company; HiiROC, which is a spin-out of the University of Hull, and received this answer.
HiiROC, a UK-based developer of “turquoise” hydrogen technology, is backed by a consortium of major industrial and financial players, including Centrica, Melrose Industries, HydrogenOne Capital Growth, Hyundai, Kia, Wintershall Dea, VNG, and Cemex Ventures. The company has raised over £40 million to develop its thermal plasma electrolysis technology.
Note the presence of two of the biggest Korean companies ; Hyundai and Kia.
HiiROC is also five times more efficient than traditional electrolysis.
Google AI says this about South Korean offshore wind.
South Korea is aggressively developing its offshore wind sector, targeting 14.3 GW to 15 GW of installed capacity by 2030, with over 116 projects and 44 GW of capacity under development. The country aims for a 2030 renewable energy share of 20-30%, leveraging floating technology for massive projects like the 3.2 GW Jindo project.
It appears to me, that South Korea will replace their market share of the jet fuel market with sustainable aviation fuel (SAF).
I’m also sure, that if the Koreans need to produce more hydrogen to make more SAF to power the world’s aircraft, Centrica will help them to rent some of our empty seas.
I can see the Koreans, with a little help from their friends, including the UK, dominating the SAF market.
Cummins To Cease New Electrolyser Activity Amid Worsening Market
The title of this post, is the same as that of this article on Renewables Now.
These are the first three paragraphs.
Cummins Inc has decided to stop new commercial activity in the electrolysers space following a strategic review of the segment launched last year, citing deteriorating market conditions and weakening customer demand.
The decision is linked to USD 458 million (EUR 388.4m) of charges for the full-year 2025 related to the electrolyser business within the company’s zero-emission technologies arm, Accelera, of which USD 415 million were non-cash charges.
The company noted that it will continue to fulfil existing customer commitments before winding down new commercial activity in the segment.
Although, I am in favour of using hydrogen as a fuel, I recognise, that traditional electrolysis is not the most efficient process.
These methods are more efficient.
HiiROC
- HiiROC use a process, that they call Thermal Plasma Electrolysis to split any hydrocarbon gas into hydrogen and carbon black.
- HiiROC originated in the University of Hull.
- Typical gases that can be used are chemical plant off-gas, biomethane and methane.
- I like the ability to use chemical plant off-gas, as some of this is particularly nasty and HiiROC may offer safe disposal.
But the big advantage is that the HiiROC process is five times more energy efficient than traditional electrolysis.
The carbon black is no useless by-product, but has several valuable uses in its own right, which are detailed in its Wikipedia entry.
These two paragraphs from Wikipedia, give a summary of the more common uses of carbon black.
The most common use (70%) of carbon black is as a reinforcing phase in automobile tires. Carbon black also helps conduct heat away from the tread and belt area of the tire, reducing thermal damage and increasing tire life. Its low cost makes it a common addition to cathodes and anodes and is considered a safe replacement to lithium metal in lithium-ion batteries. About 20% of world production goes into belts, hoses, and other non-tire rubber goods. The remaining 10% use of carbon black comes from pigment in inks, coatings, and plastics, as well as being used as a conductive additive in lithium-ion batteries.
Carbon black is added to polypropylene because it absorbs ultraviolet radiation, which otherwise causes the material to degrade. Carbon black particles are also employed in some radar absorbent materials, in photocopier and laser printer toner, and in other inks and paints. The high tinting strength and stability of carbon black has also provided use in coloring of resins and films. Carbon black has been used in various applications for electronics. A good conductor of electricity, carbon black is used as a filler mixed in plastics, elastomer, films, adhesives, and paints. It is used as an antistatic additive agent in automobile fuel caps and pipes.
It can also be used as a soil improver in agriculture.
HiiROC would appear to be five times more energy efficient than traditional electrolysis.
I would also rate the range of their investors as a particular strength.
Google AI lists these companies as investors.
HiiROC, a UK-based developer of plasma torch technology for “turquoise” hydrogen production, is backed by a consortium of industrial and strategic investors. Key investors include Centrica, Melrose Industries, Hyundai Motor Company, Kia, HydrogenOne Capital, CEMEX Ventures, Wintershall Dea, and VNG.
Note.
- CEMEX must be going to decarbonise cement making.
- Melrose describe themselves as an industry-leading aerospace technology provider.
- Will we be seeing hydrogen cars from Korean manufacturers?
- Wintershall Dea is Europe’s leading independent gas and oil company.
HiiROC has an impressive list of investors.
Bloom Energy
I wrote about Bloom Energy’s process in Westinghouse And Bloom Energy To Team Up For Pink Hydrogen.
This method also looks promising.
- Westinghouse Electric Company is an American builder of nuclear power stations.
- Bloom Energy Corporation make a solid-oxide electrolyser.
- Pink hydrogen is green hydrogen produced using nuclear power.
It uses electrolysis at a higher temperature, which speeds it up.
Desert Bloom
This is an Australian process, that I wrote about in 10GW Green Hydrogen Project Aims To Electrolyze Water Drawn From Desert Air.
Conclusion
You can understand, why Cummins are getting jumpy!
But you have to remember that when I worked in a hydrogen plant in the 1960s, the hydrogen was an unwanted by-product and it was mixed with coal gas and sent down the power station to raise steam, so that it could be used to do something useful.
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.
