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.

  1. CEMEX must be going to decarbonise cement making.
  2. Melrose describe themselves as an industry-leading aerospace technology provider.
  3. Will we be seeing hydrogen cars from Korean manufacturers?
  4. 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.

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.

H2Rescue Truck Smashes World Record With 1,806 Miles On A Single Hydrogen Fill!

The title of this post, is the same as that of this article on Hydrogen Fuel News.

This is the sub-heading.

H2Rescue Truck Sets New World Record in Hydrogen Transportation

These first two paragraphs add more detail.

A groundbreaking milestone in hydrogen-powered transportation has been achieved by the H2Rescue truck, a prototype heavy-duty vehicle capable of addressing energy challenges during disaster relief. Built by Accelera (a division of Cummins), with support from the U.S. Department of Energy (DOE) and other federal agencies, the truck recently achieved a Guinness World Record by traveling an astonishing 1,806 miles on a single fill of hydrogen fuel.

What makes this feat remarkable is the environmental implications of the technology. While a traditional internal combustion engine would have emitted 664 pounds of carbon dioxide (CO2) over the same distance, the hydrogen-fueled H2Rescue truck produced zero CO2 emissions. Hydrogen-powered vehicles like this one exemplify cutting-edge innovation in decarbonizing transportation.

This last paragraph describes the use of the vehicle in emergencies.

More than just a long-distance performer, the H2Rescue truck is an essential tool during emergencies. It can provide 25 kilowatts of power for critical relief operations, such as lighting, medical equipment, and communication systems, for up to 72 hours without refueling. This capability could make a significant difference in disaster zones, where reliable energy sources are often scarce.

Cummins are certainly serious about the innovative use of hydrogen.

Spotlight On The IVECO E-WAY H2: Less Weight, 15% More Passenger Capacity

The title of this post, is the same as that of this article on Sustainable Bus.

This is the sub-heading.

Up to seven time less batteries than a BEV bus (one module instead of 7), with 15% more passengers. These are the specifications mostly stressed by IVECO BUS when outlining the features of IVECO BUS E-WAY H2, presented at Busworld 2023 in Brussels. The bus model derives directly from the E-WAY BEV bus model

Note.

  1. The hydrogen fuel cell technology is from Hyundai.
  2. The bus is designed to be lighter in weight, which increases passenger capacity from 93 to 111 and gives an enhanced range.
  3. The driveline is from Accelera by Cummins, with a Siemens electric motor.
  4. IVECO provide the front axle and ZF the rear.
  5. Surprisingly, the bus is assembled from stainless steel panels, onto a steel floor.

It strikes me, that if the late great Colin Chapman had designed a bus, it would follow some of IVECO’s design.

Conclusion

This bus could set the standard for hydrogen-powered buses.

I particularly liked the saving in lithium compared to an electric bus.
