National Gas To Trial Gravitricity’s H2 Storage Solution
The title of this post, is the same as that of this article on The Engineer.
This is the sub-heading.
Gravitricity’s H2FlexiStore system for underground hydrogen storage could see a pilot built in 2025 after National Gas secured Ofgem funding to explore the technology.
There is then a graphic, which gives a good visual explanation.
The patented system uses lined geological shafts to store up to 100 tonnes of pressurised hydrogen at 220 bar, equivalent to about 3.33GWh of energy. Unlike natural storage such as salt caverns and disused gas fields, the shafts can be sited anywhere. Gravitricity has previously stated its preference for co-locating the storage near to renewable generation and potential major consumers of hydrogen such as heavy industry.
I can see that this simple system can have a lot of diverse uses.
In Centrica Completes Work On 20MW Hydrogen-Ready Peaker In Redditch, I talked about how Centrica had refurbished a decommissioned peaker plant.
One of these stores would keep a 20 MW peaker plant running for a week.
It would also work well with a HiiROC hydrogen system.
Hydrogen Start-Up Can Expand Thanks To Northern Powerhouse Fund
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Suiso’s technology for extracting clean fuel has been found to produce lower emissions and use less energy than common alternatives
These three paragraphs describe the finances and outline the their hydrogen generator.
Suiso, a South Yorkshire-based company developing a hydrogen generator, has raised £3 million from the Northern Powerhouse Investment Fund (NPIF).
The company plans to create generators as big as shipping containers that could power factories, hospitals and warehouses or be used at filling stations to fuel hydrogen-powered vehicles.
The new funds come from the asset manager Mercia’s equity finance fund, which is part of the NPIF, and Mercia’s enterprise investment scheme.
This paragraph describes the technology.
Suiso uses novel microwave technology to extract hydrogen from natural gas or biogas, capturing the carbon in the form of carbon black, which can be used to make tyres, batteries and inks. In 2023 the company was one of the winners of a government competition to provide technology to supply hydrogen energy.
These are my thoughts.
Suiso And HiiROC
Suiso are taking a similar route to HiiROC.
- The base feedstock is natural gas, which is mainly methane or CH4, with four planet-saving hydrogen atoms and a very naughty carbon one.
- Clever technology is then applied to the methane atoms and the carbon atom doesn’t like it, so they let go of the hydrogen atoms.
- It is then a matter of physically separating the carbon black from the hydrogen.
The difference between the two processes is that Suiso use microwave technology and HiiROC use plasma technology.
HiiROC claim their process will work with any hydrocarbon gas from biomethane through off-gas from a chemical plant to natural gas.
So I suspect, that as Suiso says it will work with biomethane, both technologies will work with virtually any hydrocarbon gas.
Uses Of Carbon Black
This Wikipedia entry gives a lot of information on carbon black.
There is a section, which is entitled Common Uses, where this is said.
The most common use (70%) of carbon black is as a pigment and reinforcing phase in automobile tires. Carbon black also helps conduct heat away from the tread and belt area of the tire, reducing thermal damage and increasing tire life. Its low cost makes it a common addition to cathodes and anodes and is considered a safe replacement to lithium metal in lithium-ion batteries. About 20% of world production goes into belts, hoses, and other non-tire rubber goods. The remaining 10% use of carbon black comes from pigment in inks, coatings, and plastics, as well as being used as a conductive additive in lithium-ion batteries.
Carbon black is added to polypropylene because it absorbs ultraviolet radiation, which otherwise causes the material to degrade. Carbon black particles are also employed in some radar absorbent materials, in photocopier and laser printer toner, and in other inks and paints. The high tinting strength and stability of carbon black has also provided use in coloring of resins and films. Carbon black has been used in various applications for electronics. A good conductor of electricity, carbon black is used as a filler mixed in plastics, elastomer, films, adhesives, and paints. It is used as an antistatic additive agent in automobile fuel caps and pipes.
There is another section, which is entitled Use in Lithium-Ion Batteries, where this is said.
Carbon black is a common conductive additive for lithium ion batteries as they have small particle sizes and large specific surface areas (SSA) which allow for the additive to be well distributed throughout the cathode or anode in addition to being cheap and long-lasting. Unlike graphite, which is one of the other common materials used in chargeable batteries, carbon black consists of crystal lattices that are further apart and promotes Li+ intercalation because it allows more pathways for lithium storage.
Carbon black has a low density that allows for a large volume of it to be dispersed so that its conductive effects are applied evenly throughout the battery. Furthermore, its arrangement of randomly distributed graphite-like crystals improves battery stability because of the decrease in the potential barrier of lithium intercalation into graphite, which ultimately affects the performance of cathodes.
Carbon black does seem to be very useful.
Suiso’s Web Site
This is Suiso’s web site.
The page is headed About Us and this is said.
Suiso is a developer of a low energy near zero emission microwave-driven methane cracking process for onsite generation of Hydrogen.
Hydrogen, the most abundant element in the universe, is rapidly emerging as a sustainable solution for the decarbonisation of the economy and a key piece of the energy transition picture in UK, Europe and around the world.
The cost and practical issues with generating and distributing Hydrogen has held back its use in most economies. Suiso’s technology uses existing electrical, natural/bio gas assets and infrastructure to produce clean low cost hydrogen. By transforming stranded ‘brown’ assets into vital hydrogen infrastructure, Suiso helps reduce CO2 emissions and enables countries throughout the world to meet challenging greenhouse gas emissions targets, quickly and cost effectively.
Suiso’s technology allows its generating units to be positioned anywhere there is a supply of natural/bio gas and electricity. Being located at the point of use eliminates the costly distribution (by truck or pipe) of H2 to the customer – delivering significant cost reductions. This allows it to offer competitively priced H2 for small to medium sized applications in developed and developing countries., including:
- H2 Fueling stations
- Biomethane (H2) conversion/decarbonisation for grid injection
- Light industrial applications
- Domestic H2 supply for small communities/towns
- Demand management/System top up
- Emergency H2 supply
It will design, build and supply these generators directly or via licensees to markets throughout the world.
Conclusion
I like this company.
Centrica Completes Work On 20MW Hydrogen-Ready Peaker In Redditch
The title of this post, is the same as that of this press release from Centrica.
This is the sub-heading.
Construction is complete on Centrica’s new 20MW hydrogen-blend-ready gas-fired peaking plant in Worcestershire, transforming the previously decommissioned Redditch power plant.
These paragraphs give more details of the project.
The plant is designed to support times of high or peak demand for electricity. Peaking plants only operate when production from renewables can’t meet demand, supporting the energy transition by maintaining a stable electricity supply. The Redditch site can power the equivalent of 2,000 homes for a full day, helping to maintain stability and reliability on the grid.
The plant is capable of using a blend of natural gas and hydrogen, futureproofing the site and supporting the UK’s transition towards a decarbonised energy system.
The Redditch peaking plant forms part of Centrica’s plans to invest between £600m – £800m a year until 2028 in renewable generation, security of supply, and its customers, including building out a portfolio of flexible energy assets. That includes the redevelopment of several legacy power stations, including the Brigg Energy Park in to a power generation and battery storage asset, and the first power station in the UK to be part-fuelled by hydrogen.
I also wrote Centrica Business Solutions Begins Work On 20MW Hydrogen-Ready Peaker In Redditch, about this project.
HiiROC
I wonder if this power station will be fitted with a HiiROC system, which will split the natural gas into two useful products; hydrogen and carbon black.
I wrote about HiiROC in Centrica Partners With Hull-Based HiiRoc For Hydrogen Fuel Switch Trial At Humber Power Plant.
I can see lots of HiiROC systems creating a hydrogen feed, to decarbonise various processes.
Whose Engines Are Used At Redditch?
Centrica still haven’t disclosed, whose engines they are using.
Iberdrola Preparing Two East Anglia Offshore Wind Projects For UK’s Sixth CfD Round
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
ScottishPower Renewables, Iberdrola’s company in the UK, is getting the East Anglia One North and East Anglia Two offshore wind projects ready for the upcoming auction round for Contracts for Difference (CfD).
These three paragraphs give more details.
This is according to project updates Iberdrola published as part of its financial results for 2023.
Iberdrola says “good progress is being made in the key engineering and design work” for the two projects and, while they were not presented in the UK’s fifth CfD Allocation Round (AR5), preparations are being made to take part in Allocation Round 6 (AR6).
The two offshore wind farms are part of the GBP 6.5 billion (around EUR 7.6 billion) East Anglia Hub project, which also includes East Anglia Three, currently in construction and expected to start delivering electricity in 2026. The 1.4 GW East Anglia Three was awarded Contract for Difference in July 2022.
It is now possible to build a table of Iberdrola’s East Anglian Hub.
- East Anglia One – 714 MW – Commissioned in 2020.
- East Anglia One North – 800 MW – To be commissioned in 2026.
- East Anglia Two – 900 MW – To be commissioned in 2026.
- East Anglia Three – 1372 MW – To be commissioned in 2026.
Note.
- East Anglia One is the largest windfarm in Iberdrola’s history
- These four wind farms are connected to the shore at Bawdsey on the River Deben.
These wind farms are a total of 3786 MW.
In addition there are RWE’s three Norfolk wind farms.
- Norfolk Boreas – 1386 MW – To be commissioned in 2027.
- Norfolk Vanguard East – 1380 MW – To be commissioned before 2030.
- Norfolk Vanguard West – 1380 MW – To be commissioned before 2030.
These wind farms are a total of 4146 MW, with a grand total of 7932 MW.
What Will Happen To The Electricity?
Consider.
- It is a lot of electricity.
- The good people of Norfolk are already protesting about the cables and pylons, that will connect the electricity to the National Grid.
- The good people of Suffolk will probably follow, their Northern neighbours.
- The wind farms are owned by Spanish company; Iberdrola and German company; RWE.
I wonder, if someone will build a giant electrolyser at a convenient place on the coast and export the hydrogen to Europe by pipeline or tanker.
- The ports of Felixstowe, Great Yarmouth and Lowestoft could probably handle a gas tanker.
- The Bacton gas terminal has gas pipelines to Belgium and The Netherlands.
In addition, there are various electricity interconnectors in use or under construction, that could send electricity to Europe.
- National Grid’s Lion Link to the Netherlands.
- NeuConnect to Germany from the Isle of Grain.
Whoever is the UK’s Prime Minister in 2030 will reap the benefits of these East Anglian and Norfolk wind farms.
In addition.
- The Hornsea wind farm will have tripled in size from 2604 MW to 8000 MW.
- The Dogger Bank wind farm will have grown from 1235 MW to 8000 MW.
- There is 4200 MW of wind farms in Morecambe Bay and around England.
They would be so lucky.
Wrightbus Hydrogen Coach Planned For 2026
The title of this post, is the same as that of this article in Bus&Coach Buyer.
This is the sub-heading.
Wrightbus‘ planned hydrogen coach is expected to be in production by 2026.
These are the first three paragraphs.
Jean-Marc Gales, Wrightbus CEO, told B&CB that a prototype model intended to demonstrate the powertrain is expected towards the end of the year.
Jean-Marc said: “The concept is ready, the predevelopment work has been done, so we are confident we can launch it in 2026.”
He says the vehicle is aimed at operators that do long distance coach journeys. “Hydrogen coaches can do up to 1,000km range and in five to ten years we will see a much higher proportion of hydrogen coaches than electrical,” he said.
Jean-Marc Gales also said this about the design challenge.
Jean-Marc said: “If you build a hydrogen coach, it’s a technical tour de force. Coach operators require six to ten cubic metres of luggage space. You need at least 50 to 60 seats and disability access and enough packaging space to put the tanks and the hydrogen cooling system and the fuel cells in. But we can do it, we have the technical expertise with fuel cells; we have the best engineers on the market for fuel cell buses. We have millions of miles with electrical and fuel cell vehicles in service since we launched them.
I haven’t ever used coaches much, but in the UK, there are some well-established long-distance markets.
These are some typical driving distances.
- Plymouth and Sunderland – 334 miles – 537 km.
- Brighton and Liverpool – 216 miles – 347 km.
- London and Edinburgh – 332 miles – 534 km.
- London and Paris – 213 miles – 343 km.
- London and Gdansk – 804 miles – 1294 km.
Note.
- Away football and fans of other sports use coaches and a 1,000 km range would certainly be needed to get Plymouth supporters to all away matches and back.
- The London and Scottish Market has been strong all my life.
- London and Gdansk would be an interesting trip in a coach. If you need one, look for Sinbad Coaches.
I certainly believe that Jean-Marc Gales and Wrightbus, are developing the technology for a worthwhile market.
Newquay Station – 9/10th February 2024
These pictures show Newquay station.
Note.
- It is a small one-platform station.
- It has a few facilities.
- It is located on the main street in the centre of the town.
This Google Map shows Newquay station.
Newquay station appears to have a very long platform.
- This page on Railway Data gives a length of 242 metres.
- It should accommodate a nine-car Class 802 train.
- The station is also close to the beach.
It looks to me that Newquay station is ready for a big surfing festival.
I have a few thoughts.
Adding A Second Platform
These pictures show the space alongside the current single track. At least for a five-car train.
Note.
- I would expect that adding a second platform could be easily done by a competent and experienced construction company.
- There would need to be new track and a set of points, so that a train could use either platform.
- Signalling would be added, so both platforms could be used, either separately or at the same time.
I also expect that the Tregoss Loop would need to be commissioned before the second platform.
Adding Charging For Battery-Electric Trains
Consider.
In GWR Trialling Transformative Ultra-Rapid Charging Train Battery, I talked about the installation of the Vivarail/GWR Fast Charge system at West Ealing station.
In Decarbonising The Mid-Cornwall Metro, I talked about using the Vivarail/GWR Fast Charge system or hydrogen to decarbonise the Mid-Cornwall Metro.
This picture shows the Vivarail/GWR Fast Charge system at West Ealing station.
I feel there would be no problem fitting one of these in one or both of the platforms at Newquay.
But I do feel that the best way to decarbonise services to Newquay, would be to fully-electrify Par station with 25 KVAC overhead wires.
- Mid-Cornwall Metro services would charge their batteries using a pantograph, every time that they reversed in the station.
- Long distance battery-electric services through the station would top up their batteries during a stop at the station.
- Locomotives with batteries will be increasingly used on freight services and charging may be needed for the locomotives used from china clay trains.
Note.
- Par and Falmouth Docks is 30.8 miles.
- Par and Newquay is 20.8 miles.
- Par and Penzance is 44.8 miles
- Par and Plymouth is 34.7 miles.
- Par and Truro is 19 miles.
Par would appear to be a station, that could be easy to electrify and is conveniently placed in the heart of services through Cornwall.
I See My First Modern 100 % Electric Truck
Where I live in Hackney, you see a lot of electric vans. Even the local deli has one.
But until yesterday, I don’t think I’ve seen a 100 % full-size electric truck, other than the famous Harrods delivery vans, which I can remember from the 1960s.
This was a sideview of the truck I saw.
Sadly, because I was trying to catch a bus, in the roadworks I described in How Not To Organise A Piss-Up In A Brewery, I was unable to take any more pictures.
This press release from Wincanton is entitled Wincanton Announces Multimillion-Pound Investment In Electric Vehicles For IKEA.
These three paragraphs give the full story.
Wincanton, a leading supply chain partner for UK business, today announces that it has made a multimillion-pound investment in electric vehicle technology to provide home delivery services for IKEA.
The investment has seen Wincanton purchase 30 electric home delivery vehicles, comprising of 10 16-tonne trucks and 20 vans, to support IKEA’s goal of reaching 100% zero emission last mile deliveries by 2025.
The new fleet is expected to save Wincanton 1,000 tonnes of carbon emissions each year, across just over 10,000 journeys per annum. The vehicles, supplied by Renault Trucks and Ford, will carry deliveries to the homes of IKEA customers across Greater London and the Southeast of England from Spring 2023.
I do feel though, that we’d see more zero-carbon trucks, if London could get its act together with hydrogen.
Decarbonising The Mid-Cornwall Metro
Although the Mid-Cornwall Metro will probably run initially using what diesel multiple units, after a year or so, the route will be converted to zero-carbon operation.
Newquay To Falmouth Docks
This map shows the Mid-Cornwall Metro.
These are current timings.
- By train can take almost three hours with changes at Par and Truro.
- By car should take 45 minutes to drive the 24.4 miles according to Google.
Note.
- The train timings are for a typical British Rail-era Diesel Multiple Unit on the branches and something smarter between Truro and Par.
- A Day Return ticket would cost £8.90 without a Railcard.
- If there was a through train, that meant you didn’t have to change trains, I estimate that the time could be as low as one hour and 35 minutes.
I feel that most travellers, who had access to a car, would use that to travel between Newquay and Truro.
Newquay To Falmouth Docks By Electric Train
I have ridden in three battery-electric trains.
- Class 379 train – Manningtree and Harwich in passenger service.
- Class 230 train – Vivarail demonstration
- Class 777 train- Liverpool Central and Headbolt Lane in passenger service.
Note.
- All were mouse-quiet.
- There was no detectable difference, when running on battery power in the trains.
It is my view that battery-electric trains are no second-class solution.
Consider.
- Newquay and Par is 20.8 miles.
- Falmouth Docks and Par is 30.8 miles.
- Newquay and Falmouth Docks is 51.6 miles.
- The maximum speed between Par and Newquay is around 30 mph
- The maximum speed between Par and Falmouth Docks is around 50-70 mph
- There are twelve intermediate stations.
- There is a reverse at Par station.
- Charging would be easy to install at Falmouth Docks, Newquay and Par.
- In Par Station – 10th February 2024, I suggested that Par station could be fully-electrified, so that expresses could have a Splash-and-Dash on their way to London and Penzance. If all platforms at Par were electrified the Mid-Cornwall Metro trains could charge from the electrification, as they reversed.
There are two main ways that the Mid-Cornwall Metro might operate.
- There would be chargers at Newquay and Falmouth Docks and trains would shuttle the 51.6 miles between the two stations.
- There would only be charging at Par and trains would after charging at Par go alternatively to Newquay and Falmouth Docks.
The first might need smaller batteries and the second would only need one charger.
Newquay To Falmouth Docks By Hydrogen-Powered Train
There is only one hydrogen-powered train in service and that is the Alstom Coradia iLint, which is running in Germany.
I feel it is very much an interim design, as Alstom has taken a diesel-mechanical Lint train and swapped the diesel for a hydrogen-powered electricity generator and an electric motor.
But Alstom are putting together a hydrogen-powered train based on an Aventra.
Note.
- The train is three cars.
- I would envisage performance of the hydrogen train would be very similar to that of a similar battery-electric train.
- I wouldn’t be surprised that refuelling of the train would not be a problem, as with all the china clay working nearby, there may well be developments to use hydrogen in the industry to decarbonise the mining.
The Mid-Cornwall Metro and Alstom’s Hydrogen Aventra could be ideal for each other.
Conclusion
I believe, that although the Mid-Cornwall Metro will start operation with diesel multiple units, it will be running in a zero-carbon mode within a few years.
Hydrogen Refuelling Site Could Attract Businesses To City – Meeting Told
The title of this post, is the same as that of this article on Yahoo News.
These are the first three paragraphs.
A hydrogen fuelling station planned for Bradford could play a key part in attracting new businesses to the city – councillors have been told.
The HyBradford facility is due to open on a former gas storage site off Bowling Back Lane in 2025, and late last year the scheme received millions worth of Government funding.
It is hoped the scheme will make Bradford a leader in the new, greener energy at a time when many companies are looking to wean themselves off fossil fuels.
What sort of businesses will the City attract?
- In Cadent’s Hydrogen-Hybrid Solar Toilet, I talked about how the sun and hydrogen backup are used to provide quiet, zero-carbon facilities for a building site.
- In Cummins Agrees To Integrate Its Hydrogen ICE Technology Into Terex® Advance Trucks, I talked about hydrogen-powered ready-mixed concrete trucks. These will help to reduce pollution levels on building sites and city streets and a local electrolyser would allow ready-mixed concrete suppliers to be located conveniently, where major contracts are in city centres.
- In £77 Million Investment For UK Heavy Duty And Commercial Vehicle Projects, I talked about a series of hydrogen transport projects being developed with Government and industry money. One project was one by Ford to develop a hydrogen-powered Transit van, which will be trialled by Ocado. If these catch on, then we will need more convenient electrolysers.
Bradford could be the first city, where companies try out ideas, that need a reliable supply of hydrogen.
It should also be noted that Bradford and Leeds are about fifteen miles apart, so Bradford’s electrolyser will probably be an ideal location for any business based in the Leeds/Bradford area.
