Hydrogen In Aviation Offers Potential For Growth And Deeper Emissions Reductions, New Study Shows

The title of this post, is the same as that of this press release from Rolls-Royce.

These five paragraphs compose the press release.

Rolls-Royce, easyJet, Heathrow and University College London Air Transportation Systems Lab (UCL ATSLab) published a report highlighting how hydrogen-powered aircraft could enable European and UK aviation to cut carbon emissions while supporting future growth.

The study, Enabling Hydrogen in the European Aviation Market, found that hydrogen in aviation offers a unique opportunity to achieve both emissions reduction and market expansion. The analysis shows that introducing hydrogen alongside Sustainable Aviation Fuel (SAF) can accelerate progress towards net zero, particularly when policy incentives reward low-carbon fuels and if hydrogen were to be included within the EU’s SAF mandate.

The research also found that targeted hydrogen infrastructure at around 20 major European airports, including Heathrow, could deliver more than 80% of the emissions benefits of full hydrogen availability across the continent. Concentrating investment at key ‘hydrogen hubs’ would therefore provide a practical and cost-effective path to early adoption.

Further modelling indicates that the earlier novel technologies, such as hydrogen, can be introduced, the more opportunity they present for CO2 emission reductions, underscoring the value of early technological transition where it is financially and technically viable.

The study is underpinned by UCL ATSLab’s Airline Behaviour Model (ABM), which represents the complexity of airline decision-making through specific behavioural variables. Building on this, the research evaluates how fuel costs, incentives and new technologies shape airline responses. This provides a research-based, realistic picture of how hydrogen adoption could evolve, highlighting both opportunities and potential challenges for adoption.

Note, these two sentences recommending early adoption of hydrogen.

  1. Concentrating investment at key ‘hydrogen hubs’ would therefore provide a practical and cost-effective path to early adoption.
  2. Further modelling indicates that the earlier novel technologies, such as hydrogen, can be introduced, the more opportunity they present for CO2 emission reductions.

I also suspect, that introducing hydrogen early, feeds back  to reduce Co2 emissions.

But what is Trump’s considered view on hydrogen aircraft?

Google AI gives this answer to my question.

Donald Trump’s view on hydrogen for transportation, including potential use in aircraft, is highly skeptical due to perceived safety risks and effectiveness concerns, which generally aligns with his broader opposition to green energy initiatives. He has specifically criticized hydrogen-powered vehicles as being dangerous and “prone to blowing up”.

Note.

  1. I used to work in a hydrogen factory and it’s still producing hydrogen.
  2. I doubt Trump gets on well with Jennifer Rumsey, who is CEO of Cummins, who are one of the world’s largest diesel-engine companies, who are following a zero-carbon route.
  3. Is Formula One Likely To Go To Hydrogen Fuel?  This would set the Cat Among The Pigeons

I also feel that this University College London study will create a string of converts to hydrogen.

Centrica Secures Investment Stake In Gasrec Helping Boost UK Bio-LNG Ambitions

The title of this post, is the same as that of this press release from Centrica.

This is the sub-heading.

Centrica has secured a minority stake in Gasrec, the UK’s largest dual provider of bio-LNG (bio-Liquified Natural Gas) and bio-CNG (bio-Compressed Natural Gas) to the road transport sector,

These first two paragraphs give more details.

Gasrec says the investment will drive the next phase of its infrastructure ambitions, with plans to open a UK wide network of open-access refuelling stations supplying renewable bio-LNG for the decarbonisation of heavy goods vehicles.

Centrica is taking a 16% stake and becomes one of three major shareholders in Gasrec, alongside global integrated energy company bp and private family office 44 North.

I have some thoughts.

Does Running A Truck On bio-LNG or bio-CNG. Reduce Carbon Emissions?

This paragraph from the press release, gives the thoughts of Chris O’Shea, who is Group Chief Executive, Centrica.

Chris O’Shea, Group Chief Executive, Centrica plc, said: “Demand for bio-LNG for transport is growing fast as more HGV operators make the switch – drawn by a clean, ready-to-use fuel which slashes CO2 emissions by up to 85 per cent in comparison to diesel*. This investment in Gasrec enhances our collaboration with the leading company in the sector, and puts us in a strong position to energise a vital sector of the industry on its journey to net zero.”

As Centrica is a public company, with shareholders, who would take a dim view of Mr. O’Shea telling porkies, I suspect we can assume that the following is true.

Drawn by a clean, ready-to-use fuel which slashes CO2 emissions by up to 85 per cent in comparison to diesel.

The asterisk in the full quote, refers to this note.

Low Carbon Vehicle Partnership, Innovate UK and Office for Low Emission Vehicles, Low Emission Freight & Logistics Trial (LEFT), Key Findings, November 2020. Using specific feedstocks CO2 reductions of 200% are achievable.

Centrica could be being conservative with their claims.

Decarbonising Buses, Locomotives And Trucks

Despite what Elon Musk, would have us believe, electric trucks will not dominate the future of freight transport.

An electric truck would be the vehicle equivalent of asking Usain Bolt to run a hundred metres with a large refrigerator on his back.

Trucks are going to need a fuel without a weight penalty and with a long range.

I asked Google for information about Cummins diesel, natural gas and hydrogen engines and received this AI Overview.

Cummins offers engines powered by diesel, natural gas, and hydrogen. While diesel engines are well-established, Cummins is also developing both natural gas and hydrogen engines, particularly focusing on hydrogen as a pathway to zero-carbon solutions for various applications. Cummins utilizes a fuel-agnostic platform, meaning a common base engine can be adapted for different fuel types, including diesel, natural gas, and hydrogen.

Recently, GB Railfreight purchased thirty Class 99 locomotives from Stadler.

  • They can use electrification, where it exists.
  • Where electrification doesn’t exist, they can use an onboard Cummins diesel engine, which is built in Darlington.
  • In electric-mode, they have 6.2 MW of power, and are the most powerful locomotives ever to run on UK railways.
  • In diesel-mode, they have 1.8 MW of power, which is more than enough to haul a large container train in and out of Felixstowe.

I had thought that at some future date, Cummins would convert these locomotives to electro-hydrogen.

But now that Gasrec is providing bio-LNG and bio-CNG, GB Railfreight, have the option of converting both hydrogen and biomethane.

Similar logic can be applied to Wrightbus’s Streetdeck Ultroliner, one version of which is fitted with a Cummins engine, that can be converted to electric, hydrogen or natural gas, which of course includes biomethane. This page on the Wrightbus web site describes the bus.

Wrightbus are also going back into coach manufacture, as I wrote about in Wrightbus Goes Back To The Future As It Relaunches The Contour Coach. As with the Streetdeck Ultroliner, Cummins seem to be providing one of the power units.

It seems to me, that the zero- and low-carbon revolution in transport will generate a need for the availability of biomethane, hydrogen and natural gas fuel for transport all over the country.

Gasrec with around twenty biomethane fuelling points around the country, seem well-placed to supply the biomethane in bio-LNG or bio-CNG  form.

Could Gasrec Deliver Hydrogen?

Various bus companies in the UK, have had difficulty getting the fuel for their hydrogen buses.

I believe that delivering hydrogen would be very similar to delivering LNG and if Gasrec can deliver LNG successfully and safely, they probably have the technology to do the same for hydrogen.

Centrica Seem To Be Assembling An Interesting Consortium

These are some deals, that I have reported on this blog, that involve Centrica.

Note.

  1. A lot of these deals are are about hydrogen production.
  2. Some of these deals are about biomethane production.
  3. None of these deals talk about getting hydrogen and biomethane to customers.

It appears to me, that Gasrec have a model that works to get hydrogen, methane and biomethane from production and storage to the end customers.

Developing A Rural Hydrogen Network

In Developing A Rural Hydrogen Network, I talked about supplying all those millions of off-gas grid properties with hydrogen for heating, agricultural and industrial purposes, in the countryside of the UK.

Gasrec have the technology to decarbonise the countryside.

Conclusion

Gasrec would appear to be a very useful partner for Centrica.

Centrica Really Can’t Lose At Sizewell

The title of this post, is the same as that of this article in The Times.

This is the sub-heading.

Centrica’s £1.3 billion investment in Sizewell C guarantees substantial returns, even with cost overruns.

These two-and-a-half paragraphs explain the funding.

Now we know what Ed Miliband means by his “golden age of nuclear” — golden for the companies putting their money into Sizewell C. Yes, reactor projects have a habit of blowing up private investors. But maybe not this one. It looks more like an exercise in transferring risk to consumers and the taxpayer.

Sure, nobody builds a £38 billion nuke on a Suffolk flood plain without a frisson of danger. But the energy secretary and his Treasury chums have done their bit to make things as safe as possible for the companies putting in equity alongside the government’s 44.9 per cent stake: Canada’s La Caisse with 20 per cent, British Gas-owner Centrica (15 per cent), France’s EDF (12.5 per cent) and Amber Infrastructure (7.6 per cent).

For starters, nearly all the debt for the 3.2 gigawatt plant, three-quarters funded by loans, is coming from the state-backed National Wealth Fund. It’s bunging in up to £36.6 billion, with £5 billion more guaranteed by a French export credit agency.

It looks to me that between them the British and French governments are providing £41.5 billion of loans to build the £38 billion nuke.

These are my thoughts.

Hydrogen And Sizewell C

This page on the Sizewell C web site is entitled Hydrogen And Sizewell C.

Under a heading of Hydrogen Buses, this is said.

At Sizewell C, we are exploring how we can produce and use hydrogen in several ways. We are working with Wrightbus on a pilot scheme which, if successful, could see thousands of workers transported to and from site on hydrogen double decker buses. You can read more about the pilot scheme in our press release

Firstly, it could help lower emissions during construction of the power station. Secondly, once Sizewell C is operational, we hope to use some of the heat it generates (alongside electricity) to make hydrogen more efficiently.

This would appear to be a more general statement about hydrogen and that the following is planned.

  1. Hydrogen-powered buses will be used to bring workers to the site. A press release on the Sizewell C web site, talks about up to 150 buses. That would probably be enough buses for all of Suffolk.
  2. Hydrogen-powered construction equipment will be used in the building of the power station.
  3. It also talks about using the excess heat from the power station to make hydrogen more efficiently. I talk about this process in Westinghouse And Bloom Energy To Team Up For Pink Hydrogen.

This is a substantial investment in hydrogen.

Centrica And Electricity From Sizewell C

The article in The Times, also says this.

Even so, there’s a fair bit of protection for the likes of Centrica, which has also agreed a 20-year offtake deal for its share of Sizewell’s electricity. The price of that is not yet known.

Nothing is said in the article about the size of Centrica’s electricity offtake.

  • If they get 15 % of Sizewell C, that would by 480 MW.
  • If they get 15 % of Sizewell B + C, that would by 660 MW.

If they use their share to generate hydrogen, Suffolk would have a massive hydrogen hub.

To power the buses and construction of Sizewell C, Sizewell B could be used to provide electricity to create the hydrogen.

How Would The Hydrogen Be Produced?

Centrica, along with other companies, who include Hyundai and Kia, are backers of a company in Hull called HiiROC, who use a process called Thermal Plasma Electrolysis to generate hydrogen.

On their web site, they have this sub-heading.

A Transformational New Process For Affordable Clean Hydrogen

The web site also describes the process as scalable from small modular units up to industrial scale. It also says this about the costs of the system: As cheap as SMR without needing CCUS; a fraction of the energy/cost of water electrolysis.

If HiiROC have achieved their objective of scalability, then Centrica could grow their electrolyser to meet demand.

How Would The Hydrogen Be Distributed?

Consider.

  • Currently, the Sizewell site has both road and rail access.
  • I can still see in my mind from the 1960s, ICI’s specialist articulated Foden trucks lined up in the yard at Runcorn, taking on their cargoes of hydrogen for delivery all over the country.
  • As that factory is still producing hydrogen and I can’t remember any accidents in the last sixty years, I am fairly sure that a range of suitable hydrogen trucks could be developed to deliver hydrogen by road.
  • The road network to the Siewell site is being updated to ensure smooth delivery of workers and materials.
  • The rail access to the Sizewell site is also being improved, for the delivery of bulk materials.

I believe there will be no problems delivering hydrogen from the Sizewell site.

I also believe that there could be scope for a special-purpose self-propelled hydrogen tanker train, which could both distribute and supply the hydrogen to the vehicles, locomotives and equipment that will be using it.

Where Will The Hydrogen Be Used?

I have lived a large part of my life in Suffolk and know the county well.

In my childhood, there was quite a lot of heavy industry, but now that has all gone and employment is based on agriculture, the Port of Felixstowe and service industries.

I can see hydrogen being used in the following industries.

Transport

Buses and heavy trucks would be powered by hydrogen.

The ports in the East of England support a large number of heavy trucks.

Large Construction Projects

Sizewell C is not the only large construction project in the East of England, that is aiming to use low-carbon construction involving hydrogen. In Gallagher Group Host Hydrogen Fuel Trial At Hermitage Quarry, I talked about a hydrogen fuel trial for the Lower Thames Crossing, that involved JCB and Ryse Hydrogen.

Hydrogen for the Lower Thames Crossing could be delivered from Sizewell by truck, down the A12.

Rail

We may not ever see hydrogen-powered passenger trains in this country, but I do believe that we could see hydrogen-powered freight locomotives.

Consider.

  • The latest electro-diesel Class 99 locomotives from Stadler have a Cummins diesel engine.
  • The diesel engine is used, when there is no electrification.
  • Cummins have developed the technology, that allows them to convert their latest diesel engines to hydrogen or natural gas power, by changing the cylinder head and the fuel system.
  • Access to the Port of Felixstowe and London Gateway needs a locomotive with a self-powered capability for the last few miles of the route.

A Class 99 locomotive converted to hydrogen would be able to run with out emitting any carbon dioxide from Felixstowe or London Gateway to Glasgow or Edinburgh.

 

Ports

Ports have three main uses for hydrogen.

  • To power ground-handing equipment, to create a pollution-free atmosphere for port workers.
  • To fuel ships of all sizes from the humblest work-boat to the largest container ships.
  • There may need to be fuel for hydrogen-powered rail locomotives in the future.

There are seven ports with excellent road and/or rail connections to the Sizewell site; Felixstowe, Great Yarmouth, Harwich, Ipswich, London Gateway, Lowestoft and Tilbury.

The proposed Freeport East is also developing their own green hydrogen hub, which is described on this page on the Freeport East web site.

Airports

Airports have two main uses for hydrogen.

  • To power ground-handing equipment, to create a pollution-free atmosphere for airport workers.
  • In the future, there is likely to be hydrogen-powered aircraft.

There are three airports with excellent road and/or rail connections to the Sizewell site; Norwich, Southend and Stansted.

Agriculture And The Rural Economy

Agriculture and the rural economy would be difficult to decarbonise.

Consider.

  • Currently, most farms would use diesel power for tractors and agricultural equipment, which is delivered by truck.
  • Many rural properties are heated by propane or fuel oil, which is delivered by truck.
  • Some high-energy rural businesses like blacksmiths rely on propane, which is delivered by truck.
  • Electrification could be possible for some applications, but ploughing the heavy land of Suffolk, with the added weight of a battery on the tractor, would probably be a mathematical impossibility.
  • JCB are developing hydrogen-powered construction equipment and already make tractors.
  • Hydrogen could be delivered by truck to farms and rural properties.
  • Many boilers can be converted from propoane to run on hydrogen.

I feel, that hydrogen could be the ideal fuel to decarbonise agriculture and the rural economy.

I cover this application in detail in Developing A Rural Hydrogen Network.

Exports

Consider.

  • Sizewell B and Sizewell C nuclear powerstations have a combined output of 4.4 GW.
  • A rough calculation shows that there is a total of 7.2 GW of wind farms planned off the Suffolk coast.
  • The East Anglian Array wind farm alone is said in Wikipedia to be planned to expand to 7.2 GW.
  • The Sizewell site has a high capacity connection to the National Grid.

Nuclear plus wind should keep the lights on in the East of England.

Any excess electricity could be converted into hydrogen.

This Google Map shows the location of Sizewell B in relation to Belgium, Germany and The Netherlands.

The Sizewell site is indicated by the red arrow.

The offshore oil and gas industry has used technology like single buoy moorings and coastal tankers to collect offshore natural gas for decades.

I don’t see why coastal hydrogen tankers couldn’t export excess hydrogen to places around the North Sea, who need the fuel.

It should be born in mind, that Centrica have a good reputation in doing natural gas trading. This expertise would surely be useful in hydrogen trading.

Conclusion

I believe that a hydrogen hub developed at Sizewell makes sense and I also believe that Centrica have the skills and technology to make it work.

Inside A Class 99 – The UK’s Most Powerful Locomotive

The title of this post, is the same as the title of this YouTube video.

This locomotive and its siblings, which can run on both electrification and diesel is the future of rail freight in the UK and GB Railfreight have ordered thirty of them.

Hopefully, by the end of the year, I’ll see one of these locomotives running along the North London Line, through Highbury & Islington and Dalston Kingsland stations.

At the present time, there are 480 Class 66 diesel freight locomotives in the UK. A substantial amount of carbon emissions would be saved, if as many as possible of Class 66 locomotives as possible were replaced by Class 99 locomotives.

These Class 99 locomotives will literally turn the rail freight business upside down.

Can These Locomotives Be Converted from Diesel To Hydrogen Power?

Stadler or Cummins have not said, but Cummins are decarbonising the company.

Already, large American trucks fitted with the latest Cummins engines can be converted to hydrogen. I write about this in Cummins Debuts Integrated HELM Drivetrain At IAA.

Cummins are also supplying Wrightbus with engines for the next generation of low-emission bus, as I wrote about in Wrightbus StreetDeck Ultroliner Next-Gen To Get Cummins Power.

Did Stadler fit a Cummins diesel engine in a Class 99 locomotive, as they know that every Class 99 locomotive or similar locomotives for other markets can be converted to hydrogen?

It is strange but very heartening, that when we have an American President, who thinks that climate change is fake news, one of the United States, largest and most iconic companies is leading the charge to decarbonisation.

New Routemasters As Advertising Hoardings

Increasingly, New Routemasters are appearing as advertising hoardings.

Note.

  1. I am unsure if some of the products should be advertised so prominently.
  2. The last picture is of a naked bus to fill the space.
  3. I shall be adding to this gallery.

In Could London’s New Routemaster Buses Be Converted To Hydrogen Power?, I came to this conclusion.

I believe from my knowledge of Cummins and the way they work, that they will come up with a hydrogen-based solution, that will replace the Cummins diesel in these buses with a zero-carbon engine.

If Cummins don’t then someone else will.

Whoever solves the problem of converting London’s new Routemasters to hydrogen will have one of the best adverts for their product, there has ever been.

After converting London’s thousand Routemasters, the engineers could move on to anything powered by a Cummins engine.

It would be a quick, easy and affordable way to create a thousand zero-carbon buses.

Does Your Car Have A Large Capacity, Dash Mounted Refrigerator?

I suspect not, but Wrightbus’s new Contour Coach will have one for the driver and the lucky soul, who sits in the other front seat.

Wrightbus have now put the specification of the Contour coach on a page that is entitled Experience The Contour Difference.

This is the introduction.

Introducing the Wright Contour Diesel Coach, where luxury, innovation, and performance come together. Since 1946, Wright has been at the forefront of transportation innovation, shaping the future with its unwavering commitment to excellence. Today, as UK’s No.1 zero-emission bus manufacturer and one of Europe’s fastest growing brands, Wright is making a bold return to the luxury coach market with the all-new Contour Diesel Coach (available in UK and Europe). In the 1980s, Wright revolutionised the luxury coach industry with its innovative, high-end Contour models, setting new standards in design and comfort. On 5th March 2025, Wright makes a bold return to the coach market with the all-new Contour Diesel Coach, redefining performance, style, and efficiency, offering spacious interiors, advanced safety features, and a high-performance Cummins X11 Euro 6 engine delivering 400hp. With competitive pricing, reduced lead times, and full service support to ‘complete Vehicle OEM and operator support’ from Wright’s All Service One Network, the Contour is built to exceed expectations. Plus, with a 2-year or 200,000km warranty backed fully by Wright, it ensures reliability and peace of mind.

I asked Google AI if the Cummins X11 engine can be converted to hydrogen and was told this.

Yes, while not inherently designed for hydrogen from the factory, the Cummins X11 engine, like many Cummins diesel engines, can be converted to run on hydrogen fuel. This involves modifications, including changing the cylinder head and fuel system.

As I discussed in Wrightbus StreetDeck Ultroliner Next-Gen To Get Cummins Power, it appears Wrightbus are going the Cummins route, to open up the possibility of converting the vehicles to hydrogen at some point in the future.

Cummins have certainly seen a green vision. on the Road to Net Zero, which seems to go via their Darlington factory.

 

The coach specification includes.

  • Premium reclining seats for all passengers.
  • Adjustable armrests, and USB ports at every seat.
  • Safety features like 3-point seat belts and ‘buckle up’ alerts.
  • Powered doors to the lockers underneath.
  • Reversing and rear-door cameras.

Wrightbus are also promising reduced lead times, which in my experience as a part-owner of a leasing company, that financed a large number of coaches, is very much to be welcomed.

Hydrogen Fuel Cell-Powered Coaches

Two trips convinced me, that hydrogen fuel cell coaches are the way to go.

In Riding Rail Air Between Reading Station And Heathrow Terminal 5, I did what it says in the title.

I was very disappointed.

The coach may have been a nearly-new top-of-the-range model, but my journey was to the accompanying thump-thump-thump of the diesel engine. There were also no USB ports, which these days many British Rail-era trains are sporting.

In Sutton Station To Gatwick Airport By Hydrogen-Powered Bus, I also did what it said in the title.

I was very impressed and it convinced me that hydrogen fuel cell-powered coaches could be an interesting proposition.

The power unit was mouse-quiet and the bus had more than adequate performance for the route, through the Surrey Hills.

It would be a very fruitful experiment, if say a twenty-mile route to say an airport, that is currently run by a traditional diesel coach, were to be replaced by a hydrogen fuel cell-powered bus, with a more luggage-friendly interior.

  • Would passenger numbers increase?
  • Would the number of airport workers using the service increase?

I believe that in a few years diesel coaches will be filed under Betamax.

Is There A Market For A Wrightbus Hydroliner FCEV-based Hybrid Coach?

A few years ago, there was a plan, to improve public transport to Heathrow, that would have seen the Elizabeth Line to Terminal 5 extended to Staines. I went to Staines and discussed this with one of the staff at the station.

He was all for this, as it would have given staff at the airport and in the airlines, an easy route to and from work, which would mean, they didn’t have to pay to take their car, especially, when they were working difficult shifts.

A Wrightbus Hydroliner FCEV, with a hybrid interior geared to both passengers with heavy luggage and passengers and airport and airline workers with just a carry-on size bag, might appeal to some operators.

Especially for some of the night bus routes operating to Heathrow.

What Is The Collective Noun For Cement Mixer Trucks?

I took these pictures on Eldon Street and Moorgate this morning.

Note.

  1. There was obviously a big pour going on in the rebuilding of Broadgate.
  2. I suspect those outside the hotel in the street restaurant, we’re too amused by the cabaret.
  3. Cemex were providing the concrete.

Perhaps in view of the location, the collective noun is a pollution of cement mixer trucks.

In Cummins Agrees To Integrate Its Hydrogen ICE Technology Into Terex® Advance Trucks, I describe the latest design of cement mixer trucks from the United States.

This is the European-sized member of the range.

Note.

  1. Front is to the right.
  2. The engine is in the pod at the other end.
  3. The engine can be one of Cummins’s hydrogen internal combustion engines.

These trucks would be much more city-friendly.

Cummins Unveils Integrated Powertrain

The title of this post, is the same as that of this article on Big Rigs.

These four paragraphs, describe what Cummins can offer to the world’s builders of large trucks.

In recent years, Cummins has gone through a remarkable transformation, becoming a genuine powertrain supplier – from engine to transmission to axles and brakes.

Now for the first time, Cummins will showcase its new integrated powertrain at the upcoming Brisbane Truck Show next month.

This world-first display will feature the integration of a Cummins X15 engine, Eaton Cummins 18-speed Endurant speed transmission, and Meritor driveline and axles.

Cummins’ acquisition of Meritor in 2022 was a critical step for the company to be able to roll out a completely integrated powertrain.

Note that the X15 engine has a hydrogen version numbered as X15H.

Eastern Green Link 2 Moves Up A Gear Using Low Carbon Fuel For Material Handling Trucks

The title of this post is the same, as that of this press release from National Grid.

These three bullet points act as sub-headings.

  • Eastern Green Link 2 (EGL2), a high voltage direct current (HVDC) 436km subsea transmission cable connecting Scotland and England, is being delivered as a joint venture by National Grid Electricity Transmission and SSEN Transmission.
  • Project sustainability efforts are accelerating by adopting Hydrogenated Vegetable Oil (HVO) fuelled trucks to move materials in Yorkshire.
  • The introduction of HVO fuel will deliver up to 90% reduction in direct CO2 emissions.

The use of HVO fuel is good and the carbon dioxide emission savings are to be welcomed, but there is only so much of this HVO fuel available.

If hydrogen-fueled trucks were available, then this would deliver up to 100% reduction in direct CO2 emissions.

This paragraph from the press release talks about where the HVO fuel will be used.

HVO, a low-carbon biofuel made from waste vegetable oils, will be used at the Wren Hall converter station site in North Yorkshire, where 20-tonne construction trucks will transport approximately 370,000 tonnes of quarry stone from a quarry 27 miles away. This switch from conventional diesel to HVO is expected to deliver up to a 90% reduction in direct CO2 emissions and an 80% reduction in other harmful emissions such as particulate matter.

This Google Map shows the location of Wren Hall with respect to Drax power station.

Note.

  1. The six large cooling towers of the Drax power station are in the North-West corner of the map.
  2. Google Maps indicate, where they think Wren Hall is, with a red arrow.The lane running North-South to the West of the red arrow is called Wren Hall Lane.
  3. There is a legend saying BAM Nuttall Ltd Eastern Green Link 2 on the opposite side of the square of lanes to the red arrow.

Click the map to show it to a larger scale.

It looks to me, that if hydrogen could be provided on the Drax site, then the 370,000 tonnes of quarry stone from a quarry 27 miles away could be brought to the site by hydrogen-powered 20-tonne construction trucks.

So how could hydrogen be provided on the Drax site?

  • Drax is a 2.6 GW biomass power station, so I’m sure that some electricity could be used to generate hydrogen.
  • Drax is a rail-connected site, so hydrogen could be brought in by rail.
  • Depending on the amount of hydrogen needed, hydrogen could surely be brought in by road.

I feel that if hydrogen-powered 20-tonne construction trucks were available, this transfer of quarry stone could be performed carbon-free.

Conclusion

This project illustrates a problem with large infrastructure projects all over the UK.

Moving the large amounts of stone, concrete, sand and rubble into and out of construction sites generates a lot of carbon dioxide and pollution from the 20-tonne trucks employed.

If I were to be given Ed Miliband’s job of Secretary of State for Energy Security and Net Zero, one of my first actions, would be to say that all new 20 tonne construction and cement trucks would have to be zero carbon.

I suspect, that zero-carbon with trucks this size, will mean hydrogen, as the weight of the battery would destroy the mathematics of the truck.

This would obviously reduce carbon emissions, but more importantly, what would it do for the health of those working on large construction sites?

In MAN Expands Its Zero-Emission Portfolio, I show MAN’s heavy hydrogen trucks.

This is an articulated heavy hydrogen truck.

I’m sure that MAN could build a hydrogen-powered 20-tonne construction truck.

In Cummins Agrees To Integrate Its Hydrogen ICE Technology Into Terex® Advance Trucks, I talk about the solution to the cement truck problem.

This is a side view of the top-of-the-range monster.

Note.

  1. Front is to the right.
  2. I suspect the driver doesn’t have to get out of the cab to discharge the concrete.
  3. The engine is at the rear with vertical exhausts.
  4. All axles are driven.

You’d certainly notice one of these if they were to be used in the City of London.

And this is the baby of the range.

Three axles is normal for the UK. so I wonder if this machine will ever make it across the pond.

This last paragraph in the original article describes the X15H hydrogen internal combustion engine.

The X15H was showcased at the Advanced Clean Transportation (ACT) Expo in May (2023), along with its hydrogen ICE-powered concept truck. The X15H features a 700-bar pressure 80kg capacity hydrogen storage system and a range of more than 500 miles, with up to 500 horsepower.

Could one of these trucks really deliver ready-mix concrete from London to Manchester and return?

The trucks would appear to be available, so let’s get a few over and try them out.

Incidentally, if someone had told me ten years ago, there would be rear-wheel drive trucks like Volkswagen Beetles, I’d have said they were wrong in no uncertain terms.

The Wren Hall substation would appear to be an ideal trial project for hydrogen-powered construction trucks and cement trucks.

Wrightbus To Build 1,000 Zero-Emission Buses

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

This is the sub-heading.

Northern Ireland company to ramp up production by 40% and recruit hundreds more employees as it also develops the UK’’s first long-distance hydrogen coach

These are the first two paragraphs, which add more detail.

Wrightbus, the Northern Ireland bus manufacturer, could be supplying as many as 1,000 zero-emission vehicles to depots around the UK as it increases production by 40 per cent over a two-year period and takes on hundreds more workers.

The company, best known for the redesigned 21st century take on the Routemaster ordered by the former mayor of London Boris Johnson, also announced it is to spend £5 million developing the UK’s first long-distance hydrogen coach capable of travelling 1,000km (621 miles) on a single recharging of its fuel cells.

These two paragraphs describe their production and employment plans.

Jean-Marc Gales, the former senior Peugeot director who is Wrightbus’s chief executive, said production at its Northern Ireland plant would go from 1,000 vehicles last year to 1,200 this year and 1,400 in 2026.

Over the same period the company’s workforce will grow from 1,500 to 2,500.

Peter Kyle, the secretary of state for science, innovation and technology, said this.

The level of innovation at Wrightbus and their quality standards have been recognised.

That is surely rare praise for a private company from a Labour Minster.

I first wrote about Wrightbus’s new hydrogen coach in early March, when I wrote Wrightbus Goes Back To The Future As It Relaunches The Contour Coach, which was based on this Wrightbus press release, which has the same title.

I said this in my post.

Wrightbus is entering the coach market for the first time in more than 30 years with the launch of two new vehicles in the next 18 months.

The first vehicle to hit the market is the Contour, a low-emission 55-seater coach that was launched at a customer showcase event today (March 5).

It’s a case of back to the future for Wrightbus, which last produced a Contour coach in 1987 before retiring the vehicle.

The second vehicle, a zero-emission hydrogen coach – which is under development in Ballymena, Northern Ireland – will be added to the Wrightbus coach range within the next 18 months to help drive decarbonisation of the sector.

The low emission Contour has a lead time of just six months from order, which is considerably faster than the current one-to-two-year average wait customers have come to expect from the sector. Featuring a Cummins Euro 6 400BHP X11 engine and a ZF automatic gearbox, the modern-day Contour has been built with comfort in mind, with up to 55 reclining seats – each with its own USB port – alongside other modern safety features. Competitively priced and available with or without PSVAR compliance, there is also the option of the vehicle being ‘pre-prepared’, protecting the vehicle’s ‘second life’ and flexibility.

The coach has a range of bespoke options for customers to choose from and is designed to maximise luggage space and functionality.

The low emission Contour coach was to have been built in China.

But events have moved on fast in the last month, with Trump and China trading insults on tariffs almost daily.

From today’s article in The Times and a press release from the Government, which is entitled Science Secretary Hails Wrightbus As Company Pledges £25 million To Bolster UK’s Green Transport Revolution And Drive Growth, it appears that the Chinese coach has been dropped.

Could the plan now be something like this?

  • The low emission Contour coach will either be dropped, built in Ballymena or perhaps even built on JCB’s site in Texas.
  • It might possibly be advantageous to build the coach in the United States to balance the tariffs and target the North American market.
  • I would feel, that North America could be a lucrative market for the larger thousand kilometre coach.
  • With the low emission Contour coach, Cummins get a chance to show the United States their excellent hydrogen technology.
  • Trump can claim, that he’s brought jobs back to the United States.
  • If Wrightbus and/or JCB build the low emission Contour coach, they could probably create a better product and get it to market earlier.

I suspect we’ll learn more of Wrightbus’s plans in the next few weeks.
