Essex Firm’s Hydrogen Lorry On Show In Stoneleigh

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

These paragraphs describe the truck.

Tevva, the maker in Tilbury, Essex, says it is the first hydrogen fuel cell-supported truck to be designed, built and mass produced in the UK.

The company adds the vehicle has a range of up to 310 miles (500 km) via the tech, with hydrogen tanks able to be refilled in 10 minutes.

It says it wants to help the transport industry adapt to a “post-fossil fuel future”.

To that end, it developed a fuel cell to top up electric battery-powered trucks, giving them a longer range while reducing the size of the electric battery needed.

I think that this truck is a superb example of disruptive innovation.

  • Tevva have looked at the 7.5 tonne truck market and have developed a truck that fits it.
  • Using hydrogen as a range extender up to to 500 km. is probably a good fit for the use of these vehicles.
  • So many local delivery companies will look at these trucks, so they can tell their customers, that they now offer zero-carbon deliveries.
  • They will also be useful to go into cities, that charge diesel vehicles.

I also suspect, that a lot of parts follow the route pioneered by the great Colin Chapman – Borrow from other manufacturers.

I wouldn’t be surprised to see other companies following Tevva’s route all over the world.

Rolls-Royce To Develop mtu Hydrogen Electrolyser And Invest In Hoeller Electrolyser

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

These are the three main points in the press release.

  • Holdings in start-up companies in northern Germany secure Rolls-Royce Power Systems access to key green hydrogen production technology.
  • Electrolysis systems for several megawatts of power.
  • First demonstrator in 2023 using a Hoeller stack.

This is the introductory paragraph to the deal.

Rolls-Royce is entering the hydrogen production market and acquiring a 54% majority stake in electrolysis stack specialist Hoeller Electrolyzer, whose innovative technology will form the basis of a new range of mtu electrolyzer products from its Power Systems division. Hoeller Electrolyzer, based in Wismar, Germany, is an early-stage technology company that is developing highly efficient polymer electrolyte membrane (PEM) stacks, under the brand name Prometheus, for the cost-effective production of hydrogen.

This page on the Hoeller Electrolysis web site gives details of Prometheus.

  • Hoeller are planning small, medium and large electrolyser modules, the largest of which is rated at 1.4 MW.
  • Load changes of between 0 and 100 % within seconds.
  • Cold start capability.
  • It will produce 635 Kg/day.
  • They are talking of a cost of 4€/Kg.

It all sounds good to me.

This paragraph is from the press release.

Founded in 2016, Hoeller Electrolyzer has positioned itself, with Prometheus, as one of the few highly specialized expert players in the field of high-efficiency PEM electrolysis stacks. Its founder, Stefan Höller, has more than a quarter of a century’s experience of developing electrolysis technology and has already registered 14 patents connected with Prometheus. Particularly high efficiency is promised by special surface technologies for the bipolar plates which significantly reduce the use of expensive precious metals platinum and iridium as catalysts, as well as increased output pressure.

I know a small amount about electrolysis and feel that Rolls-Royce may have got themselves a high-class deal.

Rolls-Royce’s large German presence in companies like mtu, will also help to smooth any doubts about the deal.

This paragraph indicates a shared belief.

Rolls-Royce and Hoeller Electrolyzer are united by a shared belief in the opportunity of zero-carbon energy – both for power supply and the propulsion of heavy vehicles. With decades of experience and systems expertise, Rolls-Royce is going to develop a complete electrolyzer system and has a global sales and service network, which opens up the potential for significant worldwide sales.

But perhaps, this is the most significant paragraph of the press release.

Armin Fürderer, who heads up the Net Zero Solutions business unit of Power Systems, said: “We’re going to launch electrolyzers with several megawatts of power right from the start. A total output of over 100 megawatts is conceivable by combining several electrolyzers.”

A quick search of the Internet, indicates that 100 MW is the size of the world’s largest electrolysers.

Applications

I can see applications for these large electrolysers.

Rolls-Royce Power Systems

This is a sentence from the press release.

Hoeller Electrolyzer, whose innovative technology will form the basis of a new range of mtu electrolyzer products from its Power Systems division.

The Rolls-Royce Power Systems web site, has this mission statement.

The Power Systems Business Unit of Rolls-Royce is focused on creating sustainable, climate neutral solutions for drive, propulsion and power generation.

In Rolls-Royce Makes Duisburg Container Terminal Climate Neutral With MTU Hydrogen Technology, I describe one of Rolls-Royce Power Systems projects.

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

This is the first sentence.

Rolls-Royce will ensure a climate-neutral energy supply at the container terminal currently under construction at the Port of Duisburg, Germany.

There is also this Rolls-Royce graphic, which shows the energy sources.

It would appear batteries,  combined heap and power (CHP), grid electricity, hydrogen electrolyser, hydrogen storage and renewable electricity are being brought together to create a climate-neutral energy system.

Note.

  1. The system uses a large hydrogen electrolyser.
  2. I suspect the hydrogen will be generated by off-peak electricity and local renewables.
  3. Hydrogen will probably power the container handling machines, ships, trucks, vehicles and other equipment in the port.

Hydrogen appears to be used as a means of storing energy and also for providing motive power.

I would suspect, the ultimate aim is that the port will not emit any carbon dioxide.

Other ports like Felixstowe and Holyhead seem to be going the hydrogen route.

Refuelling Hydrogen Buses and Charging Electric Buses

If you look at the Duisburg system, I can imagine a similar smaller system being used to refuel hydrogen buses and charge electric ones.

  • The hydrogen electrolyser would be sized to create enough hydrogen for a day or so’s work.
  • Hydrogen would be generated by off-peak electricity and local renewables.
  • If an operator bought more buses, I’m certain that the architecture of the electrolyser would allow expansion.
  • Hydrogen fuel cells would boost the electricity supply, when lots of buses needed to be charged.
  • Any spare hydrogen could be sold to those who have hydrogen-powered vehicles.
  • Any spare electricity could be sold back to the grid.

It should be noted that manufacturers like Wrightbus have developed a range of hydrogen and electric buses that use the same components. So will we see more mixed fleets of buses, where the best bus is assigned to each route?

I have used buses as an example, but the concept would apply to fleets of cars, trucks and vans.

Green Hydrogen

Large efficient electrolysers will surely be the key to producing large quantities of green hydrogen in the future.

It appears that about 55 MWh is needed to produce a tonne of green hydrogen using existing electrolysers.

The Hoeller electrolyser appears to be about 53 MWh, so it is more efficient.

Green Hydrogen From An Onshore Wind Farm

If you look at the average size of an onshore wind farm in the UK, a quick estimate gives a figure of 62 MW. I shouldn’t expect the figure for much of the world is very different, where you ignore the gigafarms, as these will distort the numbers.

An appropriately-sized electrolyser could be added to onshore wind farms to provide a local source of hydrogen for transport, an industrial process or a domestic gas supply for a new housing estate.

A single 5 MW wind turbine with a capacity factor of around 30 % would produce around 680 Kg of green hydrogen per day.

Green Hydrogen From An Offshore Wind Farm

There are basic methods to do this.

Put the electrolyser onshore or put the electrolyser offshore and pipe the hydrogen to the shore.

I think we will see some innovative configurations.

In ScotWind N3 Offshore Wind Farm, I described how Magnora ASA are developing the ScotWind N3 wind farm.

The floating turbines surround a concrete floater, which in the future could contain an electrolyser and tankage for hydrogen.

The ScotWind N3 wind farm is designed to be a wind farm rated at 500 MW.

I can see an electrolyser on the floater, of an optimal size to make sure all electricity is used.

Pink Hydrogen

Pink hydrogen, is zero-carbon hydrogen produced using nuclear-generated electricity.

There are industrial processes, like the making of zero-carbon chemicals, concrete and steel, that will require large quantities of zero-carbon green or pink hydrogen.

Rolls-Royce are developing the Rolls-Royce SMR, which will be a 470 MW small modular nuclear reactor.

One of these placed near to a steel works and coupled to one or more 100 MW electrolysers could provide enough zero-carbon electricity and hydrogen to produce large quantities of zero-carbon green steel.

Manufacturing

Rolls-Royce and their subsidiaries like mtu, seem to be extensive users of advanced manufacturing techniques and I would expect that they can improve Hoeller’s manufacturing.

Research And Development

The press release says this about the founder of Hoeller.

Its founder, Stefan Höller, has more than a quarter of a century’s experience of developing electrolysis technology and has already registered 14 patents connected with Prometheus.

If Rolls-Royce can develop and support Stefan Höller and his team, development could easily go to a higher level.

Conclusion

I think that Rolls-Royce have taken over a company, that will in the end, will design excellent efficient electrolysers.

Volvo Trucks Showcases New Zero-Emissions Truck

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

This is the first paragraph.

Imagine a truck that only emits water vapor, produces its own electricity onboard and has a range of up to 1 000 km. It’s possible with fuel cells powered by hydrogen, and Volvo Trucks has started to test vehicles using this new technology.

This picture shows one of the trucks.

It certainly looks like a normal truck.

From the press release, it looks like Volvo Trucks are taking a conservative approach to designing, developing and launching the truck.

  • Early examples will go through an extensive test program.
  • It uses two fuel cells can generate up to 300 kW.
  • Range is quoted at up to 1000 km.
  • Fully refuelling takes 15 minutes.
  • Gross weight is up to 65 tonnes.
  • It looks to be a straight replacement for a current diesel truck.

Full launch is mentioned as towards the end of the decade, after there are enough hydrogen filling stations.

Conclusion

I may not have driven a large truck like this, but I’ve certainly funded a large number and talked with many experienced operators.

It looks to me that this could be the truck for an operator or company, who wants to offer zero-carbon transport for commercial, environmental, public relations or tax reasons.

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.

Gilbarco Veeder-Root Prepares For The Hydrogen Transport Revolution

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

This is the first two paragraphs.

Gilbarco Veeder-Root today announces a strategic mission to become a pioneer in enabling future hydrogen-powered transportation.

It is making available a suite of compression, dispensing and software solutions, allowing the creation of a network of renewable or low-carbon hydrogen refuelling stations around the world.

Two statements from the article.

  • According to most industry experts, hydrogen is better suited for heavy-duty commercial vehicles than pure electric power, due to the rapid refuelling time, their weight, and duty cycles.
  • Hydrogen fuel cell trucks and buses are currently being developed by most of the leading global truck manufacturers and it’s predicted that 15% of commercial fleets will be hydrogen powered by 2030.

It looks like Gilbarco Veeder-Root have decided to join the hydrogen party.

I find this significant, as having a good hydrogen refuelling network, that operators know they can trust, will surely encourage them to decarbonise, by changing to hydrogen fuel.

Vote Hydrogen For London

London has an air pollution problem, as do many cities around the UK and the world.

This web page from Imperial College is entitled Air Pollution Research in London.

It starts like this.

Why Do Research In London?

  • Air pollution is a very large public health issue in London. It shortens the lives of Londoner’s leading to up to 9,400 extra deaths per year.
  • We still do not fully understand the health effects of air pollution.
  • London is a good place to do air pollution research, and acts as a giant laboratory.
  • Air pollution is well recorded in London, starting in 1993 and now covering about 200 sites.
  • London has a large population and good data on health, movement and population.

Surely, 9,400 extra deaths per year are 9,400 extra deaths too many!

These pictures were taken close to where I live in Hackney, mainly on the Bals Pond Road and Moorgate.

All show heavy diesel trucks, spewing out large amounts of carbon dioxide and other emissions.

So how can we reduce the pollution from these heavy trucks?

Consider.

  • I doubt that despite what Elon Musk says, these six- and eight-wheeled trucks can’t be powered by batteries.
  • Nearly all of these trucks, never go far from London.
  • Many of these trucks could be converted to hydrogen and thus become zero-carbon.
  • When they are replaced, these trucks should be replaced by zero-carbon hydrogen trucks.

But there is one big problem. Unlike Aberdeen, Birmingham, Glasgow and a few other areas, London has no hydrogen infrastructure and the Mayor has no plans to develop one.

I will not vote for any politician, who doesn’t support developing a hydrogen infrastructure and a hydrogen policy for London.

Lidl Supermarket Chain Dumps Battery Electrics For Hydrogen Fuel Cell Fleet

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

These are a few points from the article.

  • Lidl Germany is replacing electric vehicles with hydrogen fuel cell vehicles.
  • They are the first retailer to do this in Europe.
  • They are also replacing electric fork-lifts in a major depot in France with hydrogen-powered ones.
  • The green hydrogen for the depot will be produced by Lhyfe 75 kilometres away from wind energy.
  • Lidl is also considering converting some of its delivery trucks to hydrogen.

With respect to the forklifts the article lists the advantages of hydrogen forklifts over electric.

  • Hydrogen forklifts have a 97 % availability, as opposed to 50 % for battery ones.
  • Refuelling a hydrogen forklift takes 2 to 3 minutes, whereas recharging a battery forklift can take several hours.
  • Hydrogen forklifts allow a smaller fleet.
  • Hydrogen forklifts need less refuelling bays.

The article shows some of the advantages of using hydrogen.

Conclusion

How many other supermarket groups will switch to hydrogen?

Hydrogen Fuel Cell Trucks And H2 Infrastructure Could Benefit From New Legislation

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

Politicians from both main parties in the United States are promoting a Hydrogen for Trucks Act, to support the conversion of domestic trucking from diesel to hydrogen.

These are the three main parts of the Act

  • Provide incentives for adopting hydrogen fuel cell trucks by covering the difference in cost between them and conventional diesel-powered vehicles.
  • Encourage tandem fueling station and vehicle deployment, to ensure that one doesn’t need to exist before the other is in place, solidifying the overall fueling infrastructure.
  • Collect data and establish benchmarks for various forms of fleet operation, helping to accelerate deployment by incentivizing private investment.

We could do with an Act like this in the UK.

But whereas the United States would start with hydrogen for trucks, we would probably start with hydrogen for buses.

Mayor Announces Proposals For London-Wide Pollution Charge

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

These paragraphs explain the changes.

The mayor of London has announced plans to extend the Ultra Low Emission Zone (ULEZ) across the whole of London.

Under the current scheme, drivers of older, more polluting vehicles are being charged to enter London’s north and south-circular orbital roads.

New proposals will see the scheme extend to the edges of London’s boroughs in 2023.

I believe in this, as in many things, that the carrot is more powerful than the stick.

So we need to encourage people to change to electric or hydrogen-powered vehicles.

  • There are not enough electric charging points.
  • There are not enough hydrogen filling stations.
  • Installing and building more might encourage people to go zero-carbon.

But surely, the biggest drop in pollution would come from encouraging large London-based fleets of trucks to go zero-carbon. These would include.

  • Refuse trucks.
  • Cement trucks.
  • Skip trucks.
  • Large trucks used to transport aggregates and spoil from building sites.

It is unlikely, that many of these will ever be electric. The batteries would be just too heavy.

But many will go hydrogen or dual fuel, where they can use diesel and hydrogen.

I think there are various measures that would encourage the companies running these trucks to switch to hydrogen.

  • Following Birmingham, which has bought a few hydrogen buses and installed an electrolyser to provide their hydrogen fuel, which will be available to all users.
  • Once there is a good network of hydrogen stations, this might encourage owners of fleets of trucks to convert to hydrogen.
  • Once owners of taxis and Chelsea tractors, see lots of trucks and buses running on hydrogen, would they switch?

If I was the Mayor, I would offer a Mayor’s Prize to the company or borough, that has done most to cut pollution and/or carbon emissions.

Some mayors would enjoy giving out that prize.

Aberdeen Unveils UK’s First Green Hydrogen Waste Truck

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

These are the first three paragraphs.

The UK’s first green hydrogen-fuelled waste collection vehicle has been unveiled in Aberdeen.

While typical waste trucks are powered by diesel and petrol, the new vehicle will use green hydrogen from existing refuelling infrastructure in Aberdeen.

The truck will start collecting waste and recycling around the city from early March and will be the first hydrogen-powered waste truck to become operational in the UK.

I feel, that this is one of the obvious applications for hydrogen trucks.

  • They return to the same depot at the end of the day and if the hydrogen refuelling station is nearby or at the depot, refuelling would be no more hassle than with diesel.
  • The trucks are probably too large for battery power.
  • They tend to work a lot in areas, where there are a lot of people about, like residential streets and shopping centres.
  • Workers will be exposed to less pollution, as they bring bins to the trucks.

Aberdeen Council have provided this video.

I can see lots of Councils at least thinking of following Aberdeen’s example, when they renew their refuse trucks.

Incidentally, I may be only 74, but I can still remember the horse-drawn waste carts that Wood Green Council used to use in the 1950s. They were used around Wood Green town centre, where trailers were parked to receive rubbish from shops and businesses. Horses were used to move them about and to the depot. In the end they horses were replaced by Scammel Mechanical Horses.
