Have We Missed The Boat On Fracking?
I have just re-read my post from October 2019, which was entitled Fracking Hell…Is It The End?, where these were my conclusions.
- Fracking for hydrocarbons is a technique that could be past its sell-by date.
- The use of natural gas will decline.
- INEOS could see hydrogen as a way of reducing their carbon footprint.
- The heating on all new buildings should be zero carbon, which could include using hydrogen from a zero-carbon source.
- There are reasons to think, that electricity from wind-farms creating hydrogen by electrolysis could replace some of our natural gas usage.
So will the Government’s lifting on the ban on fracking make any difference?
The announcement is detailed in this article on the BBC, which is entitled Fracking Ban Lifted, Government Announces.
These are my thoughts.
Fracking Is Not A Quick Fix
My personal view is that to achieve any significant amounts of gas from fracking will take some years, so it is not something that will be available in the short term.
Opposition To Fracking Won’t Help
There are very few inhabitants of the UK, who are enthusiastic about fracking.
Opposition to fracking will make it less likely to be the feasible short term fix we need in the UK.
Suppose There Was An Earthquake Near To A Fracking Site
Fracking also has the problem, that if there were to be a small earthquake near to a site, even if it was very likely to have not been caused by fracking, it would result in massive public uproar, which would shut down all fracking in the UK.
This to me is a big risk!
Would The Jackdaw Oil And Gas Field Be A Medium Term Solution?
- In Shell’s Jackdaw Gas Field Given Go-Ahead By Regulators, I wrote about Shell’s Jackdaw field, which has been given the go-ahead.
- It could be able to provide 6 % of North Sea gas production.
- It should be fully operational by 2025.
I believe that with other gas field developments and imports, Jackdaw could keep us supplied with enough gas until the end of the decade.
Future Renewable Electricity Production
In Will We Run Out Of Power This Winter?, I summarised the likely yearly additions to our offshore wind power capacity in the next few years.
- 2022 – 3200 MW
- 2023 – 1500 MW
- 3024 – 2400 MW
- 2025 – 6576 MW
- 2026 – 1705 MW
- 2027 – 7061 GW
Note.
- Ignoring 2022 as it’s going, this totals to 19.2 GW.
- Hopefully, by the end of 2027, Hinckley Point C will add another 3.26 GW
- According to Wikipedia, there are currently 32 active gas fired combined cycle power plants operating in the United Kingdom, which have a total generating capacity of 28.0 GW.
I think it is not unreasonable to assume that some of the electricity will enable some of our gas-fired power stations to be stood down and/or mothballed.
Gas consumption would be reduced and some power stations would be held in reserve for when the wind was on strike!
Using Hydrogen To Eke Out Our Gas
Consider.
- In Lime Kiln Fuelled By Hydrogen Shown To Be Viable, I wrote about how hydrogen can be used instead of or with natural gas to fuel a lime kiln.
- There are other processes, where hydrogen can be used instead of or with natural gas.
- Using more hydrogen will reduce the amount of carbon dioxide emitted.
Perhaps we should strategically build a few huge hydrogen electrolysers, so that some large industrial users can cut back on their natural gas.
Will Energy Storage Help?
Energy storage’s main use is to mop up all the surplus electricity when demand is low at a low price and sell it back, when demand is high.
If we waste less energy, we will use less gas.
Will District Heating Schemes Help?
Consider.
- In Eden Project: Geothermal Heat Project ‘Promising’, I wrote about the Eden Project’s plan to extract heat from a borehole.
- In ‘World-First’ As Bunhill 2 Launches Using Tube Heat To Warm 1,350 Homes, I wrote about a district heating scheme in Islington, that uses heat from the London Underground.
- In Exciting Renewable Energy Project for Spennymoor, I wrote about a district heating scheme, that uses heat from abandoned coal mines.
More schemes like this should be developed, where there is a readily-available source of heat or electricity
Conclusion
As we add more renewables to our energy generation, it appears to me, that our gas usage will decline.
If we were to go fracking, we should have done it a lot earlier, so we can bridge the short term gap.
Ricardo Partners On Innovative Hydrogen-Electric Train Trial
The title of this post, is the same as that of this press release from Ricardo Rail.
This is the introductory paragraph.
Ricardo, in partnership with Scottish Power, Network Rail Scotland and the University of Leeds, have received next phase energy sector funding to develop their innovative Holistic Hydrogen Approach to Heavy Duty Transport (H2H) project, which aims to be a catalyst that will help the UK remove all diesel trains from the network by 2040.
Of all British companies, one of those with most to lose from world-wide decarbonisation and the phase out of petrol and diesel is Ricardo.
Ricardo plc is an unusual company, which started life as Engine Patents Ltd in 1915.
For over a hundred years, they have been the go-to company, if you have a tricky design problem, with your diesel or petrol engines or the transmission.
Wikipedia has a list of technologies that shaped the company’s first 100 years.
I used to know the grandson of the company’s founder; Sir Harry Ricardo and he told me, that virtually every modern diesel or petrol engine in the world, has been designed with help from one or more of the company’s patents.
So decarbonisation has meant that Ricardo has diversified and their innovative Holistic Hydrogen Approach to Heavy Duty Transport (H2H) project has been one of the results.
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.
Alstom’s Coradia iLint Successfully Travels 1,175 km Without Refueling Its Hydrogen Tank
The title of this post, is the same as that of this press release from Alstom.
This paragraph describes the trip.
Alstom, global leader in smart and sustainable mobility, has demonstrated the effectiveness of its hydrogen powered solutions for long distance transportation. During a long-distance journey, an unmodified serially-produced Coradia iLint train covered 1,175 kilometres without refuelling the hydrogen tank, only emitting water and operating with very low levels of noise. The vehicle used for this journey comes from the fleet belonging to LNVG (Landesnahverkehrsgesellschaft Niedersachsen), the transport authority of Lower Saxony, and has been in regular passenger operation on the network of evb (Eisenbahnen und Verkehrsbetriebe Elbe-Weser GmbH) since mid-August. For the project, Alstom also partnered with the gas and engineering company Linde.
The distance is around 730 miles.
This paragraph describes the detailed route.
Starting in Bremervörde, the route took the Coradia iLint across Germany. From Lower Saxony, where the hydrogen train was built and developed by Alstom, it travelled through Hesse to Bavaria, all the way to Burghausen near the German-Austrian border before coming to a stop in Munich. Following this remarkable journey, the train will now head for the German capital. Several trips through Berlin are on the agenda as part of InnoTrans 2022, the premier International Trade Fair for Transport Technology, to be held from 20 to 23 September.
It looks to be a good test of a hydrogen-powered train.
It looks like Alstom believe that hydrogen trains can replace diesel ones, providing there is a source of hydrogen.
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.
Hydrogen Tourist Transport Network Trialled In The Peak District
The title of this post, is the same as that of this article on Fleet News.
This paragraph outlines the trial.
A trial is taking place in the Peak District National Park where hydrogen fuel cell electric vehicles (FCEVs) and electric vehicles (EVs) will run together between multiple destinations and attractions.
Note.
- Toyota will provide the buses.
- Air Products is providing hydrogen.
- The services appear to be centred on Chesterfield station.
It looks like one of the objectives is to test the two types of buses against the terrain.
I can see hydrogen-powered buses being used extensively in tourist areas all over the world.
Proposals Submitted To Create Darlington To Dales Rail Link
The title of this post, is the same as that of this article on the Durham County Council web site.
These paragraphs outline the proposals.
The proposals will focus on development of the Darlington-Dales corridor, improving the connectivity of towns and villages along the Weardale line. It will also review the possibility of providing a link to Crook.
This new rail link would support economic development along the Darlington-Dales corridor, helping to attract visitors and boost spend in these areas by connecting tourism sites including Hamsterley Forest, Bishop Auckland town centre, the Durham Dales, and the Weardale Railway.
The enhanced rail connectivity would also enable residents to access wider education and job opportunities, while reducing the environmental impact of the county’s transport system by providing an alternative to cars.
It looks at first glance to be practical proposals, that could be easily achieved without spending a fortune.
As Teesside has a plentiful supply of hydrogen and is even planning a depot for hydrogen trains, what would new Alstom Aventra hydrogen trains between Weardale and Saltburn via Darlington, do for tourism in the area?
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.
- The new fleet seem to have a slightly different front end with a snow plough, and a new colour scheme.
- 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.
Should The World Call A Halt To Large Nuclear Power Stations?
When I left Liverpool University in the 1960s with an engineering degree, my fellow graduates and myself felt that nuclear power would be a sensible way to provide the electricity we need. Aberfan and other disasters had ruined coal’s reputation and not one of my colleagues joined the National Coal Board.
Over the intervening years, nuclear power has suffered a greater proportion of adverse events compared to other forms of electricity generation.
Large nuclear has also suffered some of the largest time and cost overruns of any energy projects.
My optimism for nuclear power has declined, although I do hope and feel, that small modular factory-built reactors, like those proposed by Rolls-Royce and others, might prove to be as reliable and economic as gas-fired, hydro-electric and tidal power stations, or solar and wind farms.
The smaller size of an SMR could be advantageous in itself.
- Smaller factory-built power stations are more likely to be built on time and budget.
- The amount pf nuclear material involved is only about twenty percent of that of a large nuclear station.
- A smaller site would be easier to protect from terrorists and Putinistas.
- Would the risk of a serious accident be reduced?
- SMRs would be less of a blot on the landscape.
- SMRs would not need such a high-capacity grid connection.
- An SMR integrated with a high temperature electrolyser could be the easiest way to generate hydrogen for a large customer like a steelworks.
Overall, I believe an SMR would be involve less risk and disruption.
Zaporizhzhya
Zaporizhzhya is probably the last straw for large nuclear, although the incident isorchestrated by an evil dictator, who is much worse, than any of James Bond’s cruel adversities.
I doubt Putin would get the same leverage, if Zaporizhzhya were a gas-fired or hydroelectric power station.
Conclusion
I feel, the world must seriously question building any more large nuclear power stations.
