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.
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.
- Centrica Enters Into Long Term Natural Gas Sale & Purchase Agreement
- Centrica And PTT Sign Heads Of Agreement For Long-Term LNG Supply
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.
Could Wrightbus’s New Hydrogen Coach Do A London Scotland Round Trip On A Full Load Of Hydrogen?
Victoria Coach Station And Edinburgh
I have just looked up on the National Express web site and found that I can leave Victoria Coach Station at 22:00 and arrive in Edinburgh at 07:40 the following morning for a ticket price of £29.90.
The road distance would appear to be 638.1 km, which would be a 1276 km round trip. So I would expect that, there would need to be refueling in the round trip.
Victoria Coach Station And Glasgow
I have just looked up on the National Express web site and found that I can leave Victoria Coach Station at 23:00 and arrive in Glasgow at 07:40 the following morning for a ticket price of £23.90.
The road distance would appear to be 652.1 km, which would be a 1300 km round trip. So as with Edinburgh, I would expect that, there would need to be refueling in the round trip.
A Refuelling Strategy
Consider.
- I would expect that a refuelling strategy would minimise, the carrying of large amounts of hydrogen, through the centre of London or any other conurbation.
- The Southern Uplands of Scotland already host a lot of wind farms, including the UK’s largest onshore wind farm at Whitelee, which has a capacity of 539 MW.
- An electrolyser to produce hydrogen is being developed at Whitelee, which is 32.8 km South of Glasgow.
- Newport Pagnell services is 86.5 km. from the Southern end of the M1.
- Toddington services is 62 km. from the Southern end of the M1.
I wonder if two refuelling points, say 50-100 km. from each end of the route, would be a safe an efficient way to fuel the coaches?
Some Services Between London And Scotland
They are in South to North order.
Toddington Services
Toddington Services is 62 km. from the Southern end of the M1.
This map shows the services.
Note.
- There is land around the services that could be used to create more parking for hydrogen coaches.
- There doesn’t appear to be much space for a large wind farm to provide electricity to generate hydrogen.
- The Midland Main Line runs up the Eastern side of the map.
I wonder, if hydrogen could be brought to a refuelling site at Toddington services by the use of rail wagons.
Newport Pagnell Services
Newport PagnellServices is 86.5 km. from the Southern end of the M1.
This map shows the services.
Note.
- The services are labelled as Leicester Forest East.
- The services are tightly surrounded by houses.
I’m not sure the residents would like to have a hydrogen refuelling station in their midst.
Northampton Services
Northampton Services is 104.5 km. from the Southern end of the M1.
This map shows the services.
Note.
- It looks a rather complicated services.
- It might be too far from London.
- Provision of hydrogen might be difficult.
I think that this is another services that we can discount.
Watford Gap Services
Watford Gap Services is 120.8 km. from the Southern end of the M1.
This map shows the services.
Note.
- There is land around the services that could be used to create more parking for hydrogen coaches.
- There doesn’t appear to be much space for a large wind farm to provide electricity to generate hydrogen.
- The West Coast Main Line runs through the centre of the services.
I wonder, if hydrogen could be brought to a refuelling site at Watford Gap services by the use of rail wagons.
Rugby Services
Rugby Services is 137.8 km. from the Southern end of the M1.
This map shows the services.
Note.
- There is land around the services that could be used to create more parking for hydrogen coaches.
- It is at Junction 1 of the M6.
There is also a gas compressor station nearby, so I wonder, if a HiiROC system could be located here to extract hydrogen from the natural gas.
This map shows the location of the Churchover compressor station, with relation to Rugby services.
Note.
- The compressor station is in the North-West corner of the map.
- Rugby services are in the South-East corner of the map.
- From labels on the map it appears, a solar farm might be planned by the compressor station.
With a system like HiiROC creating turquoise hydrogen from natural gas, this could be a major filling station for hydrogen-powered trucks, coaches and cars.
Conclusion
It looks to me, that Toddington services would be best, but there would need to be a large increase in capacity, if a large number of hydrogen coaches, were going to fill up at Toddington for their trip into London.
The alternative would be to give the coach a large enough hydrogen tank for a complete round trip.
