The Prototype Affordable Zero-Carbon Small Car Has Just Been Designed
The Wrightbus Ultroliner EU6, is their latest diesel bus.
The product page has this sub-heading.
A Choice Of The
UK’s Most Efficient
Diesel Buses
Two paragraphs give full details of the bus.
The StreetDeck Ultroliner EU6 is available with two ultra low emission efficient diesel engine choices: the new Cummins 6.7 litre 6 cylinder and the current Mercedes 5.1 litre 4 cylinder engine. Our StreetDeck EU6 Ultroliner and its engine choices remains the UK’s favourite. All these buses can be repowered at mid-life to zero-emission BEV technology with NewPower.
The new Cummins ISB6.7 litre six-cylinder diesel engine, married with the latest Voith DIWA.8 NXT 7-speed transmission. Two power options are available: 250Hp / 187Kw, 1000Nm and 300Hp / 224Kw, 1200Nm. With a large 245L fuel tank, this StreetDeck is ready to go the distance, wherever the journey takes it. Its MH3 technology helps lower fuel consumption during frequent stops on busy roads and improves the overall footprint and ride quality. Where ultra clean diesel buses are seen as the only option at this time, there is no better bus than the low emission StreetDeck Ultroliner range.
So you get a modern bus, that can be converted to zero-carbon at an appropriate time.
But nothing is said about conversion to hydrogen, which I believe is the ideal fuel for a large vehicle.
So I asked Google AI, if a Wrightbus Ultroliner can be converted to hydrogen-power, and received this answer.
Yes, the Wrightbus StreetDeck Ultroliner EU6 can be converted to hydrogen power. Wrightbus has engineered the diesel StreetDeck Ultroliner platform to be forward-looking, allowing operators to retrofit these vehicles mid-life with Cummins hydrogen internal combustion engines.
Here are the key details regarding this conversion and technology:
Adaptable Design: The StreetDeck Ultroliner was specifically designed to bridge the gap between traditional diesel and zero-emission options, making it possible to switch to hydrogen or battery-electric powertrains later in the vehicle’s life.
Hydrogen Internal Combustion: Instead of a fuel cell, this retrofit converts the diesel engine to run on hydrogen gas, providing a cost-effective route to zero emissions for existing operators.
Shared Platform: The diesel Ultroliner shares a similar “feel and features” with the purpose-built zero-emission Hydroliner (Hydrogen Fuel Cell) and Electroliner (Battery) buses, making the structural integration of alternative systems more straightforward.
Alternative Conversion Options: Third-party companies, such as Equipmake, specialize in “repowering” Wrightbus StreetDeck models to zero-emission, offering to convert diesel vehicles to electric in a short time frame, although the primary official pathway mentioned by Wrightbus for the Ultroliner is hydrogen-combustion.
The Wrightbus StreetDeck Hydroliner FCEV (Fuel Cell Electric Vehicle) was the world’s first production hydrogen double-decker bus, providing proven technology in cities like Aberdeen, Belfast, and London.
Note.
- The original Cummins diesel engine is converted to hydrogen fuel.
- In Cummins Fuel-Agnostic X Series Platform, I show a Cummins video, which explains their philosophy of convertible engines with trucks.
- Conversion to natural gas is also possible.
- It would appear that the Cummins ISB in the Ultroliner has a hydrogen version, that can be created by changing the fuel system and the cylinder head.
I wouldn’t be surprised, if Cummins told me, that they could make a convertible diesel, that could power a small hatchback.
Out of curiosity, I asked Google AI, “What is the power of a diesel Mini” and received this answer.
The power of a diesel Mini depends on the model (One D, Cooper D, or Cooper SD) and the generation, with power outputs ranging from approximately 88 bhp to 170 bhp. Diesel Minis are known for high torque and excellent fuel economy rather than just top-end speed.
Here is a breakdown of the power figures:
1. MINI Cooper SD (2.0L Diesel)
Power: Typically 143 bhp (105 kW) to 170 bhp (125 kW).
Torque: 305 Nm to 360 Nm (225–265 lb-ft).
Performance: The 170 hp 2.0-litre diesel in the 2015-2018 range is often called a “diesel hot hatch,” featuring a 0-62 mph time of around 7.3 seconds.
2. MINI Cooper D (1.5L – 1.6L Diesel)
Power: Usually between 110 bhp and 116 bhp.
Torque: 270 Nm (199 lb-ft).
Performance: Offers a good balance of fuel economy and punch, with a 0-60 mph time of around 9.4–9.7 seconds.
3. MINI One D (1.4L – 1.5L Diesel)
Power: Approximately 75 bhp to 95 bhp.
Performance: Designed for maximum fuel efficiency and lower tax bands, with lower power output compared to the Cooper models.
Key Takeaways:
Most Powerful: The 2.0L Cooper SD is the most powerful, often producing up to 170 hp.
Torque: Diesel Minis often have high torque at low revs (around 1750rpm), making them quick for overtaking and city driving.
Generation Differences: Older R56 models (2007-2014) often have 1.6L diesel engines, while newer F56 models (2014-2024) use 1.5L or 2.0L engines.
Reliability: These engines are BMW-sourced (N47 or B37/B47) and generally considered reliable.
As there are large numbers of companies around the world, who claim they can convert cars and other vehicles, and engines to hydrogen power.
Out of curiosity, I asked Google AI, “Has Anybody Built A Hydrogen-Powered Mini” and received this answer.
Yes, BMW built a hydrogen-powered MINI Cooper prototype in 2001.
Unveiled at the Frankfurt Motor Show in September 2001, this car was not a fuel-cell vehicle, but rather a hydrogen-burning internal combustion engine car.
Key details about the 2001 MINI Cooper Hydrogen:
Engine: It used a modified version of the MINI’s 1.6-liter four-cylinder engine designed to run on hydrogen.
Technology: It was unique because it used cryogenic liquid hydrogen and injected it while super-cooled, which increased engine efficiency and performance, setting it apart from other hydrogen experiments at the time.
Packaging: Engineers managed to place the contoured hydrogen tank under the rear seats, meaning it did not sacrifice cabin or cargo space compared to a standard Mini.
Legacy: While not mass-produced, it was a significant prototype in BMW’s long-standing research into hydrogen technology.
Other Hydrogen “Mini” Projects:
Mini Mirai RC Car: Toyota and Tamiya built a 1/10th scale hydrogen-fuelled remote-controlled car in 2021. It used a small fuel cell and hydrogen canisters to run for twice the duration of a conventional battery-powered RC car.
Small Engines: Israeli firm Aquarius Engines has developed a 10kg hydrogen-powered engine intended for use as a range extender, which has passed independent testing.
Conclusion
I believe that in the next few years, a serious manufacturer will release a diesel car that can be converted to hydrogen power.
Eventually, this will mean that government can withdraw fossil fuels for road vehicles.
EU Nuclear Push Opens Door For More Pink Hydrogen
The title of this post, is the same as that of this article on H2-View.
These four paragraphs introduce the article.
The European Commission has given a renewed push to nuclear development, which may open the door for more pink hydrogen.
Direct, large-scale pink hydrogen production in Europe is currently very limited, as the industry is still in its pilot and policy-alignment phase. Over 95% of European hydrogen is still produced from fossil fuels, primarily through steam methane reforming.
Speaking at the Nuclear Energy Summit, President Ursula von der Leyen pledged €200m to support private investment in nuclear technologies and unveiled a new European strategy for small modular reactors with the aim that they are operational by the early 2030s. Funding will come from the Emissions Trading System.
“After years of declining investment, we need more to turn the tide,” she said.
It is certainly an article worth giving a good read, as it is a view from the very top.
Bid To Create UK’s First Regional Hydrogen Network
The title of this post is the same as this article on the BBC.
This is the sub-heading
Four energy companies are working together to bid for government funding to develop the UK’s first regional hydrogen transport and storage network.
This two paragraphs add more details to the article.
National Gas, Centrica, Equinor and SSE Thermal aim to secure about £500m of funding to develop the network, which will connect sites across the Humber region.
“This is a competitive process that will determine where the UK’s first integrated hydrogen network is built,” a spokesperson for the four companies said.
Note.
- There are already several hydrogen projects in the area including Aldbrough Hydrogen Storage, H2H Saltend, and Ferrybridge and Keadby Next Generation Power Stations.
- The local MPs seem in favour.
- In Could Doncaster Sheffield Airport Become A Hydrogen Airport?, I laid out my reasons, why Doncaster Sheffield Airport could become a hydrogen airport.
I can see this hydrogen cluster having a big future.
New Baltic Sea Interconnector On Horizon As Lithuania, Latvia, and Germany Plan Cross-Border Link
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Lithuania, Latvia, and Germany are planning a joint offshore interconnector that would enable electricity trading between the Baltic countries and Germany and allow for the integration of up to 2 GW of offshore wind capacity in Lithuania and Latvia
These first two paragraphs add more detail to the article.
The energy ministers of the three countries signed a joint declaration of intent on 18 February, paving the way for the development of the Baltic-German PowerLink interconnector, which would, in addition to electricity trading and offshore wind capacity integration, also enable the expansion of onshore renewable energy capacity.
The Lithuanian, Latvian, and German transmission system operators (TSOs) – Litgrid, Augstsprieguma tīkls and 50Hertz – agreed to assess the feasibility of the hybrid electricity interconnection.
As Germany, has the following connections under development in the West.
- AquaVentus to Aberdeen, Humberside, Denmark, Norway and The Netherlands.
- NeuConnect to the Isle of Grain In England.
- GriffinLink, which is an offshore link to England.
The Germans seem to be putting themselves at the centre of an energy distribution system, that has the capability to stabilise European and UK electricity for thousands of years. Especially, if the network grows to include more countries.
This paragraph says this about the Baltic-German PowerLink project.
The Baltic-German PowerLink project concept developed by Litgrid, Augstsprieguma tīkls, and 50Hertz includes a 2 GW, approximately 600 kilometres long hybrid offshore connection, with the connection point in the Baltic States planned to be on the border between Lithuania and Latvia. The exact location is to be determined after technical studies.
Note.
- The interconnectors may be long, but they are not longer than anything built successfully before in European waters.
- The UK and the Island of Ireland are well-linked.
- There would appear to be no need for challenging projects like the Morocco-UK Power Project
I suspect that Germany will get the energy it needs and the British Isles will get a nice little earner.
If Europe is generating large amounts of wind and solar energy with its variable output it will need lots of energy storage.
What Countries Have The Terrain For Pumped Storage Hydro In Europe?
I asked Google AI and received this answer.
Key countries with ideal, high-elevation terrain and significant existing or planned capacity include:
Alpine Region (The Heart of European Pumped Storage):
Switzerland: Extremely high capacity due to steep, mountainous landscapes and significant water sources, hosting the world’s oldest working pumped storage plant.
Austria: Heavily mountainous, it is a major player in PSH expansion and modernization.
France: Home to one of Europe’s largest, the Grand Maison hydroelectric power station.
Italy: Holds high capacity with numerous planned projects.
Germany: Strong existing infrastructure.
Southern Europe:
Spain: Features some of Europe’s largest plants (e.g., La Muela/Cortes-La Muela).
Portugal: Significant recent investment in large-scale projects like the Tâmega complex.
Other Potential Areas:
Norway: High potential due to its mountainous, water-rich terrain.
United Kingdom: High project volume currently under construction.
Balkans & Central Europe:
Countries like Bulgaria, Romania, and the Czech Republic have suitable terrain for further development.
These countries benefit from significant hydraulic head (steep drop) and natural or artificial reservoir potential, making them ideal for storing energy for peak consumption hours.
Note.
- As expected, the Alpine region is Top of the League.
- The UK is holding its own despite its small mountains.
- There is a lot of potential to be developed.
But then Electric Mountain in Snowdonia is certainly at the top table of pumped storage systems despite being built in the 1980s.
What Countries Have The Terrain For Hydrogen Storage In Europe?
I asked Google AI and received this answer.
Key European countries with suitable geological terrain—specifically salt caverns and depleted gas fields—for large-scale, underground hydrogen storage include Germany, the Netherlands, Denmark, the United Kingdom, and France. Other significant regions for storage potential include Spain, Hungary, and Austria, which are developing porous storage facilities.
Key Regions & Terrain Types:
Salt Caverns (North-Western Europe): Germany, the Netherlands, Denmark, France, and the UK have substantial salt deposits suitable for creating caverns, identified as cost-efficient for large-scale storage.
Depleted Gas Fields (Porous Rock): The Netherlands, Germany, and parts of Central/Southern Europe (Spain, Hungary) have significant capacity in existing porous storage, particularly in the North Sea region.
Specific Projects: Germany (Uniper’s Krummhörn project), Netherlands (HyStock), and France (HYPSTER at Etrez) are active, with Spain and Denmark emerging as major hydrogen hubs.
Capacity Potential: The Netherlands, for instance, holds massive potential (35-60 TWh) due to its offshore and onshore depleted fields.
Salt cavern projects, which offer high-deliverability storage, are heavily concentrated in the North-Western European industrial corridor.
I was lucky enough have a tour of ICI’s salt mine in Cheshire, when I worked there in the 1960s and I remember these facts from those days.
- There was enough salt in the ground under Cheshire to last several thousand years.
- Most salt was extracted from boreholes, for making chlorine using electrolysis and the Castner-Kellner process.
- Hydrogen was a by-product and much of it was mixed with coal gas to raise steam for the works.
The same technique used to make boreholes to extract the salt, is used to hollow caverns in the salt to store gases like hydrogen.
Once, when they were digging salt out of the salt mine at Winsford, a worker broke into an unmarked borehole and ICI nearly lost the mine because of the water rushing in.
Two stories stand out from the rescue of the mine.
- There was a need for dry clothes for all the workers, so ICI took a truck to Marks & Spencer in Northwich and emptied it of anything they might need. I was told the story enriched with plagues of locusts.
- A Ford Transit was found to have travelled a few thousand miles underground in axle deep salt slurry. Rather, than scrap it and buy another, it was offered back to Ford, who were delighted to swap it for a new one. I heard that Ford said, that the accelerated corrosion research would have taken many years, if done on the roads.
Always think out of the box.
Two Thirds Of Sofia Wind Turbines Installed
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Seventy wind turbines have been installed at RWE’s Sofia offshore wind farm in the UK, according to a Notice to Mariners recently issued by the project team.
These two paragraphs give more details of the installation process.
The first of the project’s 100 Siemens Gamesa SG 14-222 DD wind turbines was installed in March 2025, and the work reached the halfway mark in September last year. The vessel deployed for the work is Cadeler’s Wind Peak, which is carrying components for six turbines per trip, operating from the port of Hull.
IWS service operation vessel (SOV) IWS Seawalker is supporting the wind turbine installation work.
Note.
- Sofia is being installed by German Company ; RWE.
- Sofa will use 14 MW Siemens Gamesa wind turbines, some of which have recyclable blades.
- The installation process is being carried out nearly 200 kilometers out to sea on the Dogger Bank.
The power will be connected to the grid at Lackenby substation, which is near the Wilton chemical works, which can certainly you the electricity.
Does Wilton Chemical Works Have A Power Station?
I asked GoogleAI, the question in the title of this section and received this reply.
Yes, the Wilton International industrial site (formerly associated with ICI chemical works) has multiple power stations and significant on-site energy generation, operated primarily by Sembcorp Utilities UK. The site features a biomass power station (Wilton 10), a further biomass unit (Wilton 11), and an energy-from-waste plant, supplying electricity and steam to chemical and industrial businesses on-site.
Note.
- Wilton 10 opened as a biomass power station in 2002.
- Wilton 11 opened as a biomass power station in 2016.
I seem to remember, that one of these power stations was there on my visits to Wilton for ICI in the 1970s.
Key details regarding power generation at Wilton:
Biomass & Waste-to-Energy:
The site transitioned from coal-fired units to renewable biomass and waste-to-energy, utilizing wood and other byproducts for power and heat generation.
Sembcorp Utilities:
Sembcorp operates the site’s energy infrastructure, which includes five different generation assets and a private wire network.
Capacity: The site hosts significant generation capacity, including a 52MW biomass unit and a 35MW unit.
Future Projects: The site is involved in developments for net-zero emissions, including the Whitetail Clean Energy project, which is planned as the UK’s first Net Zero emissions power plant with Carbon Capture and Storage (CCS).
The site serves as a “plug and play” industrial location offering on-site, cost-effective energy.
Conclusion
This would appear to be a sensible small power system providing 1400 GW of wind power, backed up if needed be by the two biomass units, which total 87 MW.
Note, that ICI were storing gases under the site for many years, so I suspect, that Carbon Capture and Storage, might work well at this location.
I can see other places, where a wind farm, is combined with energy from waste for backup.
Are Wind Farms Being Backed Up By Energy From Waste Units In The UK?
I asked GoogleAI, the question in the title of this section and received this reply.
Yes, but only in a limited, complementary capacity, rather than as a direct, large-scale substitute for wind power.
Energy from Waste (EfW) units—commonly known as incinerators—are increasing in the UK, but their role in the grid is different from how we “back up” wind.
Here is a breakdown of how it works:
1. The Role of EfW (Baseload, not Backup)
Baseload Generation: EfW plants run 24/7 to burn waste. They provide a steady, consistent, predictable “baseload” of electricity (about 2–3% of UK supply).
Intermittency: Because they run constantly, they cannot ramp up and down quickly when the wind stops blowing. Therefore, they are not a “flexible” backup in the same way gas power plants are.
Partial Renewable: Around 50% of the energy produced by EfW is considered renewable (organic waste), helping the UK hit green targets.
2. What Actually Backs Up Wind?
When wind farms stop producing power during low-wind periods (often called “dunkelflaute”), the UK relies on other sources:
Natural Gas Plants: These are the primary, flexible backup that can ramp up instantly to fill gaps in renewable production.
Interconnectors: Imported electricity from other countries (e.g., Norway, France).
Battery Storage: Growing, but still small-scale compared to total demand.
3. How EfW Helps the Grid
EfW does assist the grid by providing system inertia and consistent, low-carbon, on-demand energy, reducing the need for more fossil fuels to be burnt at certain times. They are particularly useful for providing power when the grid is congested, but they do not specifically act as a “spare tire” for wind farms.
4. Future Trends
The government is looking to attach Carbon Capture and Storage (CCS) to EfW units, which would make them a low-carbon, dependable, and sustainable part of the energy mix by the 2030s.
In summary: EfW plays a part in supporting a greener grid, but it is not a direct substitute for the flexibility required to back up intermittent wind power.
5. Hydrogen Power
This is a section, that artificial intelligence has unsurprisingly left out, as no country has yet built the hydrogen storage and the power stations to generate the electricity, when it is needed.
But Note.
- SSE are building a big hydrogen store in Yorkshire at Aldbrough.
- Centrica are converting the Rough gas storage to a hydrogen store.
- SSE are building a 910 MW hydrogen-powered power station at Keadby.
- SSE are building a 1200 MW hydrogen-powered power station at Ferrybridge.
I suspect if you were building a chemical plant and Wilton fitted your budget, you would take a look.
National Grid, TenneT Germany Launch GriffinLink, A First Of A Find Project To Maximise Offshore Wind
The title of this post is the sane as that of this press release from National Grid.
These three bullet points serve as sub headings.
-
National Grid and TenneT Germany announce our cooperation on GriffinLink, a planned GB-Germany multi-purpose interconnector (MPI).
-
GriffinLink would support energy security, accelerate the connection of offshore wind and mark a coordinated approach on supply chains and infrastructure.
-
Announced at the North Sea Summit in Hamburg, the project could maximise shared offshore wind resources in the most efficient way.
These two paragraphs add more detail.
National Grid will partner with TenneT Germany to develop GriffinLink, a new multi-purpose interconnector (MPI) project, which could connect British and German offshore wind to both countries. It marks a step towards a more integrated, flexible, and efficient energy system for both Great Britain and Germany which delivers secure, affordable energy for consumers.
GriffinLink could make an important contribution to security of supply and market integration in northwestern Europe. Cross-border hybrid energy systems such as GriffinLink make it possible to feed cleaner electricity into the grid where it can be generated and transport it exactly where it is needed.
Note this integrated approach means.
- Better utilisation of the grids and is a more efficient use of renewable energy across national borders;
- Lowering the costs involved, and the supply chain materials required and;
- A reduced impact on coastal communities and the environment.
As a ‘multi-purpose’ interconnector connecting wind in two countries, GriffinLink would be the first project of its kind in Europe and a milestone for cross-border energy security and stability.
It will also connect the UK’s offshore wind power to someone someone who needs it and will pay good money for it.
I asked Google AI, “How much energy we will be exporting to Europe in 2030” and received this reply.
By 2030, the UK is expected to be exporting significant amounts of electricity to Germany, largely enabled by the NeuConnect interconnector, which is set to become operational around 2028 and will have a capacity of 1.4 GW. While precise, definitive figures for 2030 are subject to market conditions, key data suggests:
NeuConnect Capacity: The 725km subsea link between Kent (UK) and Wilhelmshaven (Germany) will allow 1.4 GW of electricity to flow in either direction.
Net Export Position: The UK is positioned to become a net exporter of electricity to Europe by the 2030s, fueled by a massive expansion in offshore wind capacity, aiming for up to 50GW by 2030.
Grid Interconnection: By 2030, the UK’s total interconnection capacity to Europe is planned to increase to 18GW, up from 8GW.
Hydrogen Focus: In addition to electricity, the UK is exploring the potential to export up to 35 TWh of hydrogen to Germany by 2030.
That will do nicely!
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.
FEV And Daimler Buses Create Hydrogen Coach Demonstrator
The title of this post is the same as that of this article on Automotive World.
This is the sub-heading.
Daimler Buses and engineering firm FEV have developed a hydrogen fuel cell-powered Setra coach, marking the first hydrogen demonstrator vehicle in the coach segment for the Daimler Truck subsidiary. The H₂ Coach technology demonstrator, which was handed over to Daimler Buses in summer 2025 following approximately two years of development and approval by German technical inspection authority TÜV, offers a range of at least 800 kilometres per tank filling and is intended for testing purposes.
The article also has a picture, which shows.
- A typical modern coach design with three axles.
- Setra H2 Coach branding.
- A Slogan of “Travelling Towards a Sustainable Future”
It looks very similar to images of Wrightbus’s three-axle Contour design. But that would mean, they could fit similar infrastructure.
But when I asked Google AI, when the Wrightbus three-axle hydrogen coach would enter passenger service, I received this answer.
Wrightbus’s three-axle hydrogen fuel cell electric coach is planned for launch in 2026. The company, which is developing the vehicle in Ballymena, Northern Ireland, has confirmed the project is aimed at decarbonising long-distance travel, with a projected range of up to 1,000 km.
It would appear that Wrightbus are ahead on range and timescale.
University Of Alberta Partners With City of Edmonton And Diesel Tech Industries To Pilot Hydrogen-Diesel Bus Retrofits
The title of this post, is the same as that of this article on Pulse 2.0.
These two paragraphs introduce what is a comprehensive practical approach to decarbonising a fleet of diesel buses.
The University of Alberta is partnering with the City of Edmonton and Diesel Tech Industries to cut carbon emissions from Edmonton’s fleet of diesel-powered buses by integrating hydrogen fuel into existing combustion engines.
The initiative focuses on developing a practical retrofit approach to help transit agencies and other vehicle operators reduce emissions quickly without waiting for full fleet replacement. Project leaders say that if the pilot succeeds, the work could translate into a deployable solution for operators across Canada seeking near-term carbon reductions while maintaining current diesel assets.
Note.
- The City of Edmonton has around a thousand buses.
- Many of Edmonton’s buses have Cummins engines.
- Cummins are decarbonising the company and have developed hydrogen-conversions for some of their diesel engines.
- I am sure that this technique could be used to convert London’s thousand new Routemaster buses, with their Cummins engines.
This project seems to have a lot of possibilities to get very much larger.
The Anonymous Widower
