Hydrogen ICE Trucks Offer Lower Cost Shift Away From Diesel

The title of this post, is the same as that of this hydrogen news item from Ryse Hydrogen.

These three paragraphs put forward their view.

Truck manufacturers are offering fleet managers an alternative decarbonisation route that allows them to use clean hydrogen within a well-known environment: the internal combustion engine (ICE).

This U.S. engine giant Cummins will unveil a medium-duty concept truck powered by the H2-ICE at this week’s IAA Transportation exhibition in Hanover, Germany, while Westport Fuel Systems revealed its HPDI hydrogen ICE engine for heavy duty vehicles just last week.

Hydrogen ICE vehicles offer many of the benefits of hydrogen fuel cells housed within a technology that is already familiar to millions of mechanics and engineers around the world.

I agree with Ryse and feel that several companies are working on doing the same for smaller vehicles like cars and vans.

Rolls-Royce Releases mtu Rail Engines For Sustainable Fuels

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

The press release starts with these bullet points.

  • mtu Series 1300, 1500 and 1800 engines already released; Series 1600 and 4000 to follow shortly
  • Up to 90% CO2 savings by operating existing engines with Hydrotreated Vegetable Oil (HVO/renewable diesel)
  • Locally emission-free operation possible in combination with mtu Hybrid PowerPack
  • Field tests with DB Cargo and RDC Autozug Sylt

Note.

  1. Hitachi Class 800, 802, 805 and Class 810 trains appear to use Series 1600 engines.
  2. CAF Class 195, 196 and Class 197 trains appear to use Series 1800 engines.
  3. Class 43 power cars, as used in InterCity 125 trains appear to use Series 4000 engines.

It would appear that many of the UK’s new diesel trains and the remaining Class 43 power-cars can be converted to run on HVO.

This paragraph from the press release gives more details.

Rolls-Royce is taking a significant step towards even more climate-friendly rail transport with the release of mtu rail engines for use with sustainable fuels. With synthetic diesel fuels of the EN15940 standard, CO2 emissions can be reduced by up to 100 percent compared to fossil diesel. Hydrotreated Vegetable Oil (HVO or renewable diesel), which is already commercially available today, reduces CO2 emissions by up to 90 percent. If the fuels are produced with the help of renewable energy and green hydrogen – through what is termed a Power-to-X process – existing rail vehicles can be operated in a completely CO2-neutral manner. The mtu Series 1800 engines which are used in mtu PowerPacks, as well as Series 1300 and 1500 for locomotives and multi-purpose vehicles, are already approved for use with synthetic fuels such as HVO. Series 1600 and versions of Series 4000 engines will follow in the near future. The release of engines for climate-friendly fuels requires a series of tests and trials and Rolls-Royce has found strong partners for this activity. DB Cargo and RDC Autozug Sylt have already tested or are currently testing mtu Series 4000 engines with HVO in their locomotives.

Rolls-Royce mtu seem to have covered all issues.

This is a very significant statement in the paragraph.

If the fuels are produced with the help of renewable energy and green hydrogen – through what is termed a Power-to-X process – existing rail vehicles can be operated in a completely CO2-neutral manner.

This must be the most affordable way to make your diesel trains zero carbon.

Conclusion

Rolls-Royce and Cummins seem to be doing a thoroughly professional job in decarbonising the diesel engines they have made in recent years.

It now needs someone to take small diesel engines down the conversion route, just as Rolls-Royce mtu and Cummins are cleaning up their large engines.

Cummins Shows Hydrogen Internal Combustion-Engined Concept Truck At IAA Transportation Exhibition

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

These are the first two paragraphs.

Cummins believes hydrogen internal combustion engines (H2-ICE) will be suitable for the 10- to 26-tonne GVW range, and showed a concept vehicle at the IAA Transportation exhibition.

The truck, which is based on a Mercedes-Benz Atego 4×2, is fitted with Cummins’ new 6.7-litre B6.7H engine. It is rated at 290hp, has a peak torque of 1,200Nm, and a range of up to 500km.

Alison Trueblood, Cummins executive director – on-highway business Europe, is extensively quoted in the article and it is worth reading what she says.

I believe that by providing a hydrogen infrastructure and converting trucks to hydrogen, by using similar techniques to Cummins could be a quick and effective way to improve air qualities in urban areas.

My First Ride In A Refurbished New Routemaster

When I went to see the Queen’s flowers, that I wrote about in The Queen’s Flowers In Green Park, the 38 bus, I rode to Green Park, was a refurbished New Routemaster.

Note.

  1. It appears to have scrubbed up well.
  2. There is a new fabric and all the gold metal parts have been re-anodised.
  3. The priority seats for those with limited mobility are now labelled.
  4. As they are now up to eleven years old, will they now be good for at least another ten?

This article on Key Buses is entitled New Routemaster Refurbishment Underway, where this is said.

Despite coming under threat as a result of Tf L’s funding crisis the first New Routemasters have now returned from refurbishment. These include buses in the Abellio London, Metroline and London United fleets. The latter now carry RATPDev Transit London fleetnames. The first 200 vehicles are expected to be refurbished by March 31, 2023.

With 200 buses, I should get a lot of chances to add some more pictures.

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.

Since then I’ve written Werner Enterprises Signs Letter Of Intent Planning To Secure 500 X15H Engines From Cummins, which describes the application of Cummins technology to convert heavy trucks to hydrogen power.

Transport Enterprise Leasing To Integrate Cummins X15H Hydrogen Engine Into Heavy Duty Trucks

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

This is the first paragraph.

Transport Enterprise Leasing and Cummins Inc. announced recently that TEL has signed a letter of intent planning to purchase Cummins’ 15-liter hydrogen internal combustion engines when available. TEL will integrate the Cummins’ X15H hydrogen engines into their fleet of heavy-duty trucks.

This second paragraph is very significant.

Hydrogen engines can use zero-carbon green hydrogen fuel, produced by Cummins-manufactured electrolyzers. The projected investment in renewable hydrogen production globally will provide a growing opportunity for the deployment of hydrogen-powered fleets utilizing either Cummins fuel cell or engine power.

Cummins would appear to be aiming to be a one-stop shop to decarbonise your fleet of heavy trucks or anything that is powered by a Cummins diesel engine.

I did a small amount of work for Cummins about twenty years ago and one of the companies objectives was to be able to provide a diesel engine to fit anybody’s application.

So if someone wanted a diesel engine with a particular power, that fitted in an unusually-shaped or confined space, they would rearrange the layout of the engine to make it fit.

I suspect that London’s New Routemaster buses have a special version of Cummins B Series engine, designed for its unusual location halfway up the back stairs.

Will Cummins produce a hydrogen internal combustion engine for the New Routemaster?

  • The buses could become zero-carbon, at less cost than new buses.
  • Passengers would notice no difference in ride comfort and experience.
  • Drivers would just need to use the hydrogen systems.
  • Maintenance staff would only need to be trained n handling the hydrogen system, as much of the buses would be unchanged.
  • Cummins could sell an electrolyser to each garage.
  • London would get some good publicity for tourism.

London’s iconic bus would look the same.

Werner Enterprises Signs Letter Of Intent Planning To Secure 500 X15H Engines From Cummins

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

This is the first paragraph.

Werner Enterprises, a premier transportation and logistics provider, and Cummins Inc., a global power solutions provider, announced today Werner signed a letter of intent to purchase 500 Cummins’ 15-liter hydrogen internal combustion engines upon availability. The two companies announced earlier this year, Werner Enterprises plans to validate and integrate Cummins’15-liter natural gas and Cummins’ X15H hydrogen engines, both part of Cummins’ fuel agnostic platform, into their fleet.

More details of the X15H engine are given in this earlier press release, which is entitled Cummins Inc. Debuts 15-Litre Hydrogen Engine At ACT Expo, which has this first paragraph.

Today, Cummins Inc. debuted its 15-liter hydrogen engine at ACT Expo in Long Beach, California. This engine is built on Cummins’ new fuel-agnostic platform, where below the head gasket each fuel type’s engine has largely similar components, and above the head gasket, each has different components for different fuel types. This version, with expected full production in 2027, pairs with clean, zero-carbon hydrogen fuel, a key enabler of Cummins’ strategy to go further faster to help customers reduce greenhouse gas (GHG) emissions.

I certainly like the concept of a fuel-agnostic platform, where below the head gasket, everything is similar, and above the head gasket, there are appropriate components.

I wouldn’t be surprised to find that Rolls-Royce mtu and JCB have used a similar concept for their hydrogen internal combustion engines.

Cummins have also developed a 6.7 litre engine.

This is a paragraph from the press release.

Hydrogen internal combustion engines use zero-carbon fuel at a lower initial price of a fuel cell or battery electric vehicle with little modification to today’s vehicles. Accelerated market adoption of hydrogen engine powered vehicles is driven by the technology’s high technology maturity, low initial cost, extended vehicle range, fast fueling, powertrain installation commonality, and end-user familiarity.

I certainly feel it is the way to go technically.

Take London’s New Routemaster buses.

  • These buses are powered by a Cummins B-series engine, which has four cylinders and a capacity of 4.5 litres.
  • This engine powers large numbers of trucks and pick-ups.
  • For the UK, they are manufactured in Darlington.
  • It appears that Cummins 6.7 litre engine is a six cylinder B-series engine.

It would certainly be more affordable to change the cylinder heads of these buses and power them by hydrogen, than purchase a new fleet.

Cummins have an excellent tutorial on hydrogen internal combustion engines on their web site.

Cummins Fuel Cell Technology Powers Coradia iLint Fleet In Germany

The title of this post, is the same as that of this article on Green Car Congress.

This is the first paragraph.

Cummins is powering the world’s first fleet of hydrogen trains in Bremervörde, Lower Saxony, Germany. The Alstom Coradia iLint trains (earlier post) are outfitted with Cummins fuel cell systems and will run on the world’s first 100%-hydrogen train route in passenger operation. The first zero-emissions passenger trains in the 14-train fleet arrived in mid-summer.

I rode  the prototype in March 2019 and wrote My First Ride In An Alstom Coradia iLint.

I took this picture at the time.

Note.

  1. The new fleet seem to have a slightly different front end with a snow plough, and a new colour scheme.
  2. According to the article, the Cummins fuel cell systems were assembled in Germany.

I have a few thoughts.

Cummins Fuel Cells

I must admit, I was a bit surprised to see that Cummins fuel cells are being used, as most other companies seem to be using Ballard.

But, having worked with Cummins on diesel engine testing and seen their thoroughness, I’m sure that their fuel cells will do a good job.

Is The Cummins Choice About Marketing?

Consider.

  • Alstom has manufactured or assembled trains for the US market at Hornell, New York.
  • Cummins is a large United States company.
  • United States and Canadian railways are standard gauge, like most of Europe.
  • United States and Canadian railways have a lot of track mileage without electrification.
  • United States and Canadian railways use right hand running as does Germany.
  • The Coradia iLint doesn’t need any electrification.
  • The Coradia iLint has a range of 600–800 kilometres (370–500 mi) on a full tank of hydrogen.

I suspect that a German-specification, Coradia iLint might be possible to run in the United States and Canada, with only a different interior and signage.

If you are an Alstom train salesman in the United States, selling a commuter train to American cities and transit authorities, must be easier if the train has a substantial United States content.

I don’t think Cummins will be worried that the smart new train has their fuel cells, as it might help convert truck, van and car drivers to Cummins hydrogen technology.

I wouldn’t be surprised to learn, that Alstom got a premium deal from Cummins.

Are Hydrogen-Powered Trains Suited To North America?

Consider.

  • There is a lot of track without electrification.
  • Distances are long, which makes electrification expensive.
  • Providing hydrogen for trains should be no more difficult than in Europe.
  • In my experience hydrogen trains are a better passenger experience than diesel, in terms of noise and vibration.

I suspect that Alstom/Cummins could sell a lot of hydrogen-powered trains in the North America.

The Third Route To Zero-Carbon Transport

The two most common routes to zero-carbon transport are.

  • Battery-electric vehicles
  • Hydrogen fuel-cell vehicles

Note that most hydrogen-fuel cell vehicles also have a battery.

But I believe there’s a third route and that is the use of hydrogen in an internal combustion engine.

Earlier today, I wrote Rolls-Royce And AVK Provide Over 3.5 Gigawatts Of Emergency Power Capacity In The UK, which is based on a Rolls-Royce press release, with the same title.

This is an extract.

And this is said about the use of hydrogen.

Rolls-Royce is also currently developing its mtu gas engine portfolio for power generation so that the engines can run on hydrogen fuel in future, enabling a Net Zero energy supply. The company is also launching complete mtu hydrogen fuel cell solutions, that emit nothing but water vapor from 2025. This will enable CO2-free generation of emergency power for data centers and many other critical applications.

I certainly think, that they are going in the right direction.

Rolls-Royce mtu have a lot to lose, if their diesel engines that power trains, heavy equipment, ships and emergency power generators are replaced by other companies zero-carbon solutions.

  • Large investments will need to be made in hydrogen electrolyser and fuel cell production.
  • Some traditional factories making diesel engines will be closed and could this mean redundancies?
  • A lot of retraining of staff at both manufacturer and customer will need to be made.

But a traditional internal combustion engine, that runs on hydrogen or even both hydrogen and diesel makes the transition to hydrogen a lot less painful.

Other companies going this route include Cummins, Deutz and JCB.

Conversion Of Existing Diesel Engines To Hydrogen

Surely, if an equivalence hydrogen engine exists for all of their diesel engines, a company like Cummins or Rolls-Royce mtu can produce a sound engineering route to decarbonise some of their existing applications.

A classic application would be converting London’s Routemaster buses to hydrogen, which I wrote about in Could London’s New Routemaster Buses Be Converted To Hydrogen Power?

This was my conclusion in that post.

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.

As this is a world-wide problem, I believe that the manufacturers of cars, buses, trucks and many other vehicles will offer zero-carbon solutions for their products, as it will be necessary for survival.

If you have just bought a new diesel BMW and your government says that in two years time, diesel will no longer be available, you’re up the creek without a paddle. But if BMW can convert it to hydrogen for a small fraction of the cost of a new electric equivalent, you have a more available way out.

Shell’s Jackdaw Gas Field Given Go-Ahead By Regulators

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

These are the first two paragraphs.

Development of a major North Sea gas field has been approved by regulators.

The Jackdaw field, east of Aberdeen, has the potential to produce 6.5% of Britain’s gas output.

This is Greenpeace’s response

But environmental campaigners have condemned the move.

The activist group Greenpeace said it believed the approval could be unlawful and it was considering legal action.

“Approving Jackdaw is a desperate and destructive decision from Johnson’s government, and proves there is no long-term plan,” said Ami McCarthy, a political campaigner for Greenpeace.

I have my thoughts.

The Short Term Problem

We are all paying the high gas price, brought about by Vlad the Mad’s illegal invasion of Ukraine.

On the other hand, I am all for cutting carbon emissions, but stopping the development of the Jackdaw gas field will do nothing to cut total emissions in the short term.

In my view, the only way to cut carbon emissions is to replace the use of natural gas with hydrogen or electricity produced by renewable sources like solar, tidal, wave or wind power.

This change to every heating system and important industries like cement, chemicals, glass and steelmaking to hydrogen and renewable energy is not a short term or low-cost project. Especially whilst we’re still recovering from the pandemic and trying to handle Vlad the Mad.

We will need a supply of natural gas for a few years and if we don’t have enough gas will Greenpeace and their ilk, be happy to see everybody freezing and a large increase in unemployment?

The Government is between a rock and a hard place, where they can either bow to Greenpeace or buy Putin’s bloodstained gas, where there are two alternatives.

  • Buy liquified natural gas (LNG) from countries like Australia, Canada, Qatar or the United States.
  • Develop our own proven resources.

The advantages of taking the second route include.

  • Some of the countries from where gas is available, have bizarre views on human rights and keeping their people safe.
  • Gas is transported over long distances in a liquid form. Liquifying natural gas uses a lot of energy. Is that energy renewable?
  • Countries from where gas is available are thousands of miles away. How much carbon dioxide will be emitted liquifying and transporting it?
  • Gas from our own resources is delivered by pipeline.
  • Development of gas fields like Jackdaw, will surely create employment in the UK.

At a first look, I feel that developing Jackdaw and other similar fields, may well be a sensible option to help us through these difficult times.

Exporting Gas To Europe

If you look at the geographical position, you would feel, that the gas will be landed at St. Fergus gas terminal, which is to the North of Aberdeen.

But no! The gas will be landed at Bacton in Norfolk through the SEAL pipeline, which is 475 km. long

Could this be because Shell want to make sure the South of England gets its gas?

Possibly, but much of the UK’s gas imports arrive at LNG terminals in the South.

But Bacton has other assets, in that it has two undersea gas pipelines to the Continent. One is to Belgium and the other is to the Netherlands.

Surely, if we export our gas to other countries, then it is their business what they do with the carbon dioxide.

Not our’s or Shell’s!

Perhaps, we should develop other proven gas fields, as they will create employment in the UK and valuable exports. It will also help our friends out in Europe, in their time of need!

Will Shell Play The Market?

I have just been informed, that recently, improvements have been made to the pipelines in the area and Jackdaw’s gas could now go to St. Fergus.

This surely would give the gas from Jackdaw three destinations.

  • Scotland via St. Fergus.
  • England via Bacton
  • Europe via Bacton and the undersea pipelines.

So will Shell play the markets?

If in the future, we start to produce massive amounts of green hydrogen, I’m sure Europe, will be happy to buy that instead.

Powering Platforms With Renewable Energy

The BBC article says this.

And it plans also to re-power its offshore platforms with renewable electricity rather than burning gas.

Looking at the map, Jackdaw will not be far from the 2 GW wind farm, that Shell are developing.

Will they build a short interconnector from this wind farm to the gas platforms of Jackdaw and other nearby fields?

Will Shell Produce Hydrogen Offshore?

This article on Gas Processing And LNG is entitled Construction Of World’s Largest PEM Electrolyzer Completed.

This is the first two paragraphs.

Air Liquide has completed the construction of the world’s largest PEM (Proton Exchange Membrane) electrolyzer. Supplied with renewable energy, this unit is now producing up to 8.2 tons per day of low-carbon hydrogen in Bécancour, Québec. With this large-scale investment, the Group confirms its long-term commitment to the hydrogen energy markets and its ambition to be a major player in the supply of low-carbon hydrogen.

The new 20 MW PEM electrolyser, equipped with Cummins technology, is the largest operating unit of its kind in the world and will help meet the growing demand for low-carbon hydrogen in North America. Bécancour’s proximity to the main industrial markets in Canada and the United States will help ensure their supply of low-carbon hydrogen for industrial use and mobility. The commissioning of this electrolysis unit increases by 50% the capacity of Air Liquide’s Bécancour hydrogen production complex.

Note.

  1. This article is about a year old and electrolysers will get larger.
  2. 20 MW of electricity will produce 8.2 tons per day of low carbon or green hydrogen.
  3. It may surprise some, that the electrolyser has been built by Cummins, who are diesel engine manufacturers. They are a company, who appear to have seen the way the wind is blowing and are making sure they lead the revolution.

How much hydrogen could a 2 GW wind farm produce?

  • Wind farms have a capacity factor, which is how much energy they actually produce compared to their rating.
  • Shell’s 2 GW wind farm will be a floating wind farm and these typically have a capacity factor of at least 50 percent.
  • I will assume the capacity factor of 50 percent.

This will give 8,200 tonnes per day of green hydrogen. This is nearly three million tons per year.

How Will The Hydrogen Be Brought Ashore?

The HyDeploy project is investigating blending of hydrogen into our natural gas grid.

  • It appears that up to 25 % of hydrogen can be added without the need to change boilers and appliances.
  • This blending of hydrogen into our natural gas supply, would cut our carbon emissions by a worthwhile amount.

So will we see gas piped to nearby gas platforms like Jackdaw for blending with fresh virgin natural gas?

This would have the following advantages for Shell.

  • They wouldn’t need to install an electric cable to the shore with all its associated onshore and offshore substations.
  • The hydrogen could be brought ashore at either Bacton or St. Fergus gas terminals.
  • Shell could invite other local wind farms to share their electrolyser.
  • Shell would need to new onshore installations.

If Shell get this right, they could cut the project cost.

Will Shell Produce Blue Hydrogen Offshore?

I wonder if Shell have a cunning plan.

  • It is known, that Shell have developed a catalyst-based blue hydrogen process, which splits natural gas into hydrogen and carbon dioxide, with the addition of oxygen from the air.
  • I suspect the process could need a lot of energy to work. But at least a GW from the nearby wind farm will probably be a good start.
  • Could that carbon dioxide be captured and stored in a depleted gas field.
  • The hydrogen could be piped to either Bacton or St. Fergus, as I previously described.

This hybrid method might be a more economic way to produce zero-carbon hydrogen.

Conclusion

I wouldn’t be surprised if Shell will produce hydrogen offshore.

Daimler Truck North America And Cummins Collaborate To Drive Hydrogen Fuel Cell Trucks Forward In North America

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

This is the first two paragraphs.

Cummins Inc., a global power and hydrogen technologies leader, and Daimler Truck North America (DTNA), the largest heavy-duty truck manufacturer in North America, are collaborating to upfit and validate Freightliner Cascadia trucks with a Cummins hydrogen fuel cell powertrain for use in North America. Freightliner will leverage Cummins’ fourth generation fuel cell powertrain, which provides improved power density, efficiency and durability.

The joint effort will support both organizations’ goals to reduce emissions across product offerings and operations. Upon successful validation, the companies intend to have initial units available in 2024 for selected customers.

Note.

  1. The Freightliner Cascadia is a heavy-duty semi-trailer truck and the flagship model of Freightliner, which is a subsidiary of Daimler Truck North America.
  2. There is already an electric variant of the Cascadia, which is called an eCascadia. It is this truck, that is being converted to hydrogen.

This article on Hydrogen Fuel News is entitled Cummins Partners With Freightliner On Hydrogen Fuel-Cell Truck, starts with this paragraph.

According to Cummins CEO Tom Linebarger who spoke at the Advanced Clean Transportation (ACT) Expo, it’s the responsibility of the trucking industry to create a cleaner future. He stated that, “We think we deliver goods to market and empower things,” adding that “We do things that are essential to the economy, and we are proud of it. We also think, though, that we need to help with prosperity that has to do with making sure we don’t consume and destroy the planet that we live on.”

Cummins seem to have placed a few bets on hydrogen.

Daimler Truck North America seem to be following the philosophy of being in both the electric and the hydrogen market with two separate products, that I outlined in Daimler Trucks Presents Technology Strategy For Electrification – World Premiere Of Mercedes-Benz Fuel-Cell Concept Truck.

Wrightbus appear to have done the same with their hydrogen and electric buses.

It will be interesting to see how American truckers take to Cummins offer of a hydrogen-powered truck.
