Network Rail’s Test Track Take Centre Stage As Hydrogen Is Delivered By Rail For The First Time

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

These three paragraphs introduce the story.

Network Rail, working with rail and energy partners Freightliner and GeoPura, has transported hydrogen for the first time on Britain’s rail network, marking a major step forward for both the rail and energy sectors.

The milestone was achieved yesterday (Wednesday 3 December) at Network Rail’s Test Tracks* site in Tuxford, where freight operator Freightliner hauled a train of gas containers from Doncaster to High Marnham – marking Britain’s first shipment of hydrogen by rail.

It was part of a rail and energy industry innovation event showcasing several hydrogen initiatives. This included the first re-engineered hydrogen-powered shunting locomotive – seen as a step towards replacing diesel – another milestone towards the rail industry’s goal of becoming net zero. The event also demonstrated HPU hydrogen-powered generators, lighting towers and support vehicles.

These two paragraphs describe Network Rail’s test track at Tuxford and GeoPura’s hydrogen production facility at High Marnham.

Network Rail’s site at Tuxford runs all the way to High Marnham, where it sits adjacent to HyMarnham Power, the UK’s largest green hydrogen production facility operated by GeoPura and JG Pears. Built on the site of a former coal-fired power station, HyMarnham Power is one of the world’s first rail-connected hydrogen production facilities, and Network Rail’s Tuxford site will be the world’s first net-zero railway testing facility.

Currently, hydrogen is transported by road. This breakthrough marks a major step towards the rail network becoming a ready-made hydrogen distribution system, a rolling pipeline, with connections to all major industrial and urban centres across Britain – proving the practical capability of rail to transport hydrogen at scale. Hydrogen will also be utilised to decarbonise wider rail operations, from construction to ongoing maintenance and off-grid operations.

This OpenRailwayMap shows Tuxford and High Marnham.

Note.

  1. The blue arrow is Tuxford West junction.
  2. The North-South red track is the East Coast Main Line. East-West track indicated by the blue arrow is Network Rail’s Test Track
  3. The grey area, to the South of the Test Track in the East is the former site of High Marnham power station, where GeoPura have their hydrogen facility.
  4. If you continue East on the Test Track it connects to the Sheffield and Lincoln Line at Pye Wipe junction.

Sheffield could be the sort of city, that would need a lot of hydrogen to decarbonise.

Has  Hydrogen Been Transported From ICI’s Former Site At Runcorn By Rail

I ask this question, as I used to work at Runcorn in the 1960s, and I don’t remember seeing any hydrogen railway wagons.

I asked Google AI, the question in the title of this section and received this answer.

Hydrogen is typically transported from the INEOS (formerly ICI) site in Runcorn via pipeline or by road in cryogenic liquid tanker trucks or gaseous tube trailers, but it has not been historically transported by rail from that specific site.
The first ever trial shipment of hydrogen by rail on Britain’s network took place only very recently, in December 2025, as part of an industry innovation event. This trial involved transporting hydrogen containers from Doncaster to High Marnham, adjacent to the HyMarnham Power green hydrogen production facility.

It looks like my memory and Google AI agree.

CO2 to SAF: A One-Step Solution

The title of this post is the same as that of this article on the Chemical Engineer.

This is the sub-heading,

Oxford spinout OXCCU has launched a demonstration plant at London Oxford Airport to trial its one-step process of turning CO2 into sustainable aviation fuel (SAF). Aniqah Majid visited the plant to investigate the benefits of its “novel” catalyst

One word in this sub-heading caught my eye.

When I was a young engineer in the Computer Techniques section in the Engineering Department at ICI Plastics Division, I did a small mathematical modelling project for this chemical engineer, using the section’s PACE 231-R analogue computer.

He was impressed and gave the 23-year-old self some advice. “You should apply that beast to catalysts.”

I have never had the chance to do any mathematically modelling of catalysts either at ICI Plastics or since, but I have invested small amounts of my own money in companies working with advanced catalysts.

So when OXCCU was picked up by one of my Google Alerts, I investigated.

I like what I found.

The three raw ingredients are.

  • Green Hydrogen
  • Carbon dioxide perhaps captured from a large gas-fired powerstation like those in the cluster at Keadby.
  • OXCCU’s ‘novel’ catalyst, which appears to be an iron-based catalyst containing manganese, potassium, and organic fuel compounds.

I also suspect, that the process needs a fair bit of energy. These processes always seem to, in my experience.

This paragraph outlines how sustainable aviation fuel or (SAF) is created directly.

This catalyst reduces CO2 and H2 into CO and H2 via a reverse water gas shift (RWGS) process, and then subsequently turns it into jet fuel and water via Fischer-Tropsch (FT).

The Wikipedia entry for Fischer-Tropsch process has this first paragraph.

The Fischer–Tropsch process (FT) is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid hydrocarbons. These reactions occur in the presence of metal catalysts, typically at temperatures of 150–300 °C (302–572 °F) and pressures of one to several tens of atmospheres. The Fischer–Tropsch process is an important reaction in both coal liquefaction and gas to liquids technology for producing liquid hydrocarbons.

Note.

  1. I wouldn’t be surprised that to obtain the carbon monoxide and hydrogen or syngas for the Fischer-Tropsch process, excess hydrogen is used, so the OXCCU process may need a lot of affordable hydrogen, some of which will be converted to water  in the RWGS process.
  2. The high temperatures and pressures for the Fischer-Tropsch process will need a lot of energy, as I predicted earlier.

But I don’t see why it won’t work with the right catalyst.

The Wikipedia entry for the Fischer-Tropsch process also says this.

Fischer–Tropsch process is discussed as a step of producing carbon-neutral liquid hydrocarbon fuels from CO2 and hydrogen.

Three references are given, but none seem to relate to OXCCU.

OXCCU have a web site, with this title.

Jet Fuel From Waste Carbon

And this mission statement underneath.

OXCCU’s mission is to develop the world’s lowest cost, lowest emission pathways to make SAF from waste carbon, enabling people to continue to fly and use hydrocarbon products but with a reduced climate impact.

It looks like they intend to boldly go.

Conclusion

My 23-year-old self may have been given some good advice.

Huddersfield Station – 30th September 2025

This press release on the Network Rail Media Centre is entitled Huddersfield Station Set To Reopen Next Week With New Temporary Layout.

As it is now next week, I went to have a look at the progress today.

I made a mistake and got on a Grand Central Train, which meant, I had to change at York.

Speeding past Drax power station on the Selby Diversion, I took these pictures.

We were only in a 125 mph diesel, so we couldn’t take advantage of the 160 mph running, that the East Coast Main Line’s new signalling might allow on this section. The Wikipedia entry for the Selby Diversion, says this about the possible speeds.

The line was the first purpose-built section of high-speed railway in the UK having a design speed of 125 mph; however, research by British Rail in the 1990s indicated that the route geometry would permit up to 160 mph operation, subject to the necessary overhead line equipment and signalling upgrades. The new line also avoided the speed restriction over the swing bridge at Selby. The former ECML route, the NER’s 1871 York and Doncaster branch line, was closed from Selby northwards.

As the Selby Diversion opened in 1983, I wouldn’t be surprised that the calculations were performed on British Rail Research’s Pace 231-R, which was similar to the one I used at ICI and the pair, that NASA used calculate how to land Apollo on the moon.

When I eventually got to Huddersfield, I took these pictures.

Note.

  1. In I’ve Just Glimpsed The Future Of Train Travel Across The North Of England And I Like It, there are pictures of Huddersfield station, that were taken on the 21st August, soon after the work started.
  2. In Huddersfield Station – 15th December 2023, there are pictures of Huddersfield before the work started.
  3. Much of the work seems to have been done at the Western end of the station to lengthen the platform on the Penistone Line to Sheffield.
  4. Platform 2 for the Penistone Line has also been renumbered Platform 1.

Work still to be carried out at Huddersfield station, includes refurbishing the roof, installing the electrification and adding a couple of new platforms.

These are my thoughts.

Which Platforms Will Be Electrified?

This OpenRailwayMap shows the proposed electrification in Huddersfield station.

Note.

  1. The blue arrow in the North-East corner of the map indicates Huddersfield atation.
  2. The two red-and-black tracks going diagonally across the map are the Hudderfield Line.
  3. The red-and-black colour, indicates that the two tracks will be electrified.
  4. South of these two tracks, the Penistone Line sneaks into Platform 1 at Huddersfield station.
  5. The Penistone Line goes to Sheffield in a South-Westerly direction.
  6. There appears to be a crossover, so that trains from the Penistone Line can use both Platforms 1 and 2 in Huddersfield station.
  7. The OpenRailwayMap appears to show planned electrification between Stalybridge and Leeds stations.
  8. To the East of Leeds planned electrification is shown as far as Micklefield and Church Fenton stations.

Once installed, this electrification will create a complete electrified route across the Pennines from Liverpool Lime Street in the West to the East Coast Main Line in the East.

This OpenRailwayMap shows the planned electrification between Micklefield and Hull stations.

Note.

  1. Red tracks are electrified.
  2. Black tracks are not electrified.
  3. York is in the North-West corner of the map, with the electrified East Coast Main Line going through the station North-South.
  4. South of York, the East Coast Main Line now splits.
  5. The Western branch includes an electrified line to Micklefield station, Neville Hill depot and Leeds station.
  6. The Eastern Branch is the Selby Diversion, which is an electrified 160 mph line, that avoids the Selby coalfield.
  7. Running West-East across the map is the unlectrified Micklefield and Hull Line, which goes via Selby.
  8. Hull is in the South-East corner of the map.
  9. Hull is 42 miles from Micklefield and 36.1 miles from the Temple Hirst junction on the Selby Diversion, so it is within range of battery-electric trains, with charging at Hull station.
  10. Hitachi’s battery-electric Class 802 trains, used by Hull Trains and TransPennine Express, which are currently on test, should certainly be able to serve Hull.

Hull can become an electrified station, without the expense and disruption of full electrification.

How Long Is Platform 1 At Huddersfield Station?

This OpenRailwayMap shows the new Platform 1 at Huddersfield station.

 

Note.

The blue arrow indicates Huddersfield station.

  1. The three darker orange lines indicate the two through platforms 2 and 3, and the reconfigured bay platform 1.
  2. There is a cross-over between platforms 1 and 2, which connects Platform 2 to the Penistone Line.
  3. In the South-West corner of the map is a hundred metre scale.
  4. Using the scale, I estimate that the length of the bay platform 1 is around 120 metres.
  5. In the last two rows of pictures in the gallery of this post, a three car Class 150 train is shown in Platform 1.
  6. A three car Class 150 train is approximately sixty metres long.

Looking at the pictures, I wouldn’t be surprised if the new platform has been designed to take two three-car Class 150 trains. It would certainly take a pair of two-car Class 150 trains.

Other trains and their lengths that might use the platform include.

  • Class 170 – three-car – 70.85 metres
  • Class 195 – two-car – 48.05 metres
  • Class 195 – three-car – 71.40 metres
  • Class 195 – 2 x two-car – 96.10 metres
  • Class 810 – five-car – 120 metres

The Class 810 uses 24 metre cars, so that a pair of trains, will fit in St. Pancras. But with perhaps selective door opening could a single Class 810 train run a St. Pancras and Huddersfield service, perhaps with a split and join at Sheffield.

Electrification Across The Pennines

The TransPennine Route will be electrified between Liverpool Lime Street and Micklefield stations, once the current works between Huddersfield and Leeds are complete.

Sections without electrification include.

  • Bradford Interchange and Doncaster – 52.1 miles
  • Cleethorpes and Doncaster – 52.1 miles
  • Harrogate and Leeds – 18.3 miles
  • Hazel Grove and Doncaster – 52.6 miles
  • Hull and Micklefield – 42 miles
  • Hull and Temple Hirst junction – 36.1 miles
  •  Saltburn and Northallerton – 28.1 miles
  • Sunderland and Northallerton – 46.8 miles
  • Scarborough and York – 42.1 miles

I expect that Hitachi trains with batteries or CAF’s tri-mode trains will be able to handle these routes in a low-carbon manner.

Electrification Between Stalybridge And Huddersfield

This section is shown as being electrified on OpenRailwayMap.

But as it is only 18 miles and includes the Standedge Tunnels will the route use battery-electric trains?

Visiting The Consultation For Ferrybridge Next Generation Power Station At Knottingley

Yesterday, I visited the first meeting for the consultation on Ferrybridge Next Generation Power Station, which was held in the old town hall at Knottingley.

This Google Map shows the power station in relation to Knottingley.

Note.

  1. The meeting was held in the Knottingley Town Tall Community Centre, which is marked by the red arrow.
  2. I had arrived by train from Wakefield at Knottingley station and I was lucky enough to be able to get a taxi to the Town Hall.
  3. Knottingley station is marked on the map about  a twenty-minute walk to the West of the Town Hall.
  4. The Ferrybridge power station site is in the North-West corner of the map and appears to be bordered by the B6136 road.
  5. The A1 (M) and the M 62 motorways run North-South past the power station site.
  6. The A (M) motorway continues North-South to Newcastle and Scotland, and London respectively.
  7. The M62 motorway continues West-East to Liverpool and Manchester, and Hull respectively.
  8. The well-appointed Moto Ferrybridge services is accessible from both motorways.

This OpenRailwayMap shows the rail lines in the area.

Note.

  1. The A 62 and A 1(M) motorways running down the West side of the map.
  2. Knottingley station is on the Pontefract Line, and is marked by a blue arrow.
  3. The Pontefract Line could have connections from both East and West to the Ferrybridge power station site via Ferrybridge Power Station junction.
  4. The loop, where the merry-go-round coal trains turned, appears to be still intact at the North of the power station site.

Will these rail lines be any use in the building and operation of the new power station?

These are my thoughts.

Fuel For The Power Station

The brochure for the consultation says this about the fuel for the Ferrybridge Next Generation Power Station.

Ferrybridge Next Generation Power Station will be designed to run on 100% hydrogen, natural gas or a
blend of natural gas and hydrogen.

The brochure has an informative section, which is entitled Natural Gas Pipeline Corridors.

Additionally, I should say, that I lived within a couple of hundred metres of a major gas pipeline in Suffolk, for over twenty years and it was the most unobtrusive of neighbours.

The brochure also says this about hydrogen safety.

As with all of our sites, appropriate measures will be
in place to ensure safe operation. Hydrogen is not
inherently more dangerous than other fuel sources.

Hydrogen is flammable and must be handled with care,
just like other flammable fuels. To ignite, hydrogen
must be combined with an additional oxidising agent,
such as air or pure oxygen, in a specific concentration
and with an ignition source (a spark).

It is nearly sixty years ago now, since I worked as an Instrument Engineer, in ICI’s Castner-Kellner works at Runcorn, where hydrogen, chlorine and caustic soda were produced by the electrolysis of brine.

The plant was an unhealthy one, as it used a lot of mercury and my main task, was to design instruments to detect mercury in air and operators’ urine.

The Wikipedia entry for the Castner-Kellner process is a fascinating read and explains why it is being replaced by much better modern mercury-free processes.

I asked Google AI, if the Castner-Kellner process is still used and received this reply.

No, the Castner-Kellner process, a type of mercury cell for producing chlorine and caustic soda, is now largely obsolete due to occupational health and mercury pollution concerns, though a few plants may still operate globally. Modern chlor-alkali processes primarily use safer diaphragm cell and membrane cell technologies to produce chlorine and other chemicals from brine electrolysis.

I suspect that countries, where life is cheap, still use this process, which is very dangerous to those that work on the plant.

INEOS now own ICI in Cheshire and they still produce a large proportion of the hydrogen, chlorine and caustic soda, that the UK needs, but in a much safer way.

The question has to be asked about how hydrogen will be delivered to the Ferrybridge site.

Consider.

  • SSE are developing a large hydrogen store at Aldbrough.
  • Centrica are developing a large hydrogen store at Brough.
  • Both of these stores could be connected to the German AquaVentus system, as the Germans are short of hydrogen storage.
  • There is an East Coast Hydrogen Delivery Plan, which could probably have an extension pipeline to the Ferrybridge site.
  • The East Coast Hydrogen Delivery Plan, talks of a hydrogen capacity of 4.4 GW.

I don’t feel, that this is the sort of project, that will be delivered until the mid-2030s, at the earliest.

There is also one other important development, that will require hydrogen at Ferrybridge.

I asked Google AI, if there will be hydrogen-powered coaches by 2030 and received this reply.

Yes, there will be hydrogen-powered coaches and buses by 2030, particularly in the UK and EU, with government strategies and funding promoting their deployment, especially for routes requiring high range and quick refueling where battery-electric models may be less suitable. For example, the EU’s CoacHyfied project is developing fuel cell coaches, and the UK government envisions hydrogen playing a role in its transport decarbonization by 2030, with potential to accelerate its zero-emission bus goals.

The nearest you can get to a hydrogen-powered coach in England, is to take an upmarket Wrightbus upmarket hydrogen-powered bus between Sutton station and Gatwick Airport.

That journey convinced me of the superiority in many ways of a hydrogen bus or coach over its diesel cousins.

I believe that this superiority will see large growth in hydrogen-powered long-distance coaches in the next few years.

But I also feel that some specialist transport, like horse transport, will go the hydrogen route.

As there are services at Ferrybridge, where two important motorways cross, I can envisage that the services will need to be able to refuel passing hydrogen buses, coaches trucks and other heavy vehicles, as well as the occasional car.

So would it be possible to supply hydrogen for the motorway services, by the same route as the power station?

I believe that the hydrogen could come from Saltend to the East of Hull, so I gave Google AI the phrase “Saltend zero-carbon hydrogen” and received this reply.

Saltend is home to several initiatives for producing and utilizing zero-carbon hydrogen, most notably the H2H Saltend project by Equinor, which aims to build the world’s largest hydrogen production plant with carbon capture capabilities by 2026 to supply industrial users at the Saltend Chemicals Park. Additionally, a new green hydrogen facility is planned for the park by Meld Energy with a target operation in early 2027, and a separate low-carbon hydrogen plant by ABP, HiiROC, and px Group is also being developed to meet local industrial demand. These projects collectively contribute to the broader Zero Carbon Humber initiative, which seeks to significantly reduce industrial emissions in the region.

Note.

  1. Saltend will certainly have enough zero-carbon hydrogen for everybody who wants it.
  2. Delivery dates in a couple of years are being talked about.
  3. Local industrial demand could be satisfield using specialised trucks, just as ICI used in the 1960s.
  4. As the Germans want to connect their AquaVentus system to Humberside, any excess hydrogen, could always be sold across the North Sea.
  5. OpenRailwayMap shows that Saltend is rail-connected.

But how do you get hydrogen between Saltend and Ferrybridge?

I am sure, that hydrogen could be delivered by truck from Saltend to Ferrybridge, but would the locals allow a stream of hydrogen trucks on the roads.

On the other hand, both Saltend and Ferrybridge are both rail-connected, so would it be possible to deliver the hydrogen by rail?

Google AI says this about railway wagons for hydrogen.

Railway wagons for hydrogen transport include liquid hydrogen tank cars (tankers) for transporting cryogenic liquid hydrogen and compressed gas tank cars for carrying hydrogen in its gaseous state or bound within carrier mediums like ammonia or methanol. Hydrogen fuel cell technology is also being developed for use on trains themselves, with a hydrogen fuel cell generator wagon providing power for main-line, non-electrified freight routes.

I believe that it will be possible to develop  trains of an appropriate length to shuttle hydrogen between where it is produced  and where it is used.

Such a specially-designed shuttle train would be ideal for moving hydrogen between Saltend and Ferrybridge.

  • Once at Ferrybridge, the train would be connected to the local hydrogen system feeding the power station, the motorway services and any local businesses that needed hydrogen.
  • The trains could be hydrogen fuel cell powered, so they could use any convenient route.
  • Like hydrogen powered buses, I suspect they could be mouse quiet.
  • The trains would be sized to perhaps deliver a day’s hydrogen at a time.
  • There could only be minor changes needed to the rail system.
  • If required, the trains could could deliver their cargo in the dead of night.

It could even be based on the contept of the TruckTrain, which I wrote about in The TruckTrain.

The British Mini Nuclear Fusion Reactor That Actually Works

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

This is the sub-heading.

The only functional model in the world is so small it fits on a table and is set to help diagnose and cure cancer

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

There are a few things that mark this nuclear fusion reactor out as unusual. For one, it is rather small: it could fit on a table top. For another, this research model currently has a little more gaffer tape than you might expect of the energy technology of the future.

But the biggest difference between it and its competitors is that this nuclear fusion reactor, in a warehouse north of Bristol, is actually working. And it is on the cusp of doing something more unusual still: making money.

It almost makes you think, that it should be filed under Too Good To Be True!

In the late 1960s, I shared an office at ICI Mond Division in Runcorn, with a guy, who was working on a process to make acetylene by a revolutionary route.

The process never worked, but now it has turned up being used by a company called HiiROC to make hydrogen.

They are also backed by some big names like Centrica, Hyundai, Kia and others.

I wonder how many other old ideas are finally ripe for developing, due to improvements in manufacturing and systems to control them.

Can You Measure Blood Pressure At The Ankle?

Consider.

  • As long, as I can remember my left foot has always been larger than my right.
  • Over the last few years increasingly, my left foot has often been a stronger shade of red, than my right.
  • I also know, that after my stroke a specialist physiotherapist found that my left leg was stronger than my right.

I also know that I have a strange leaky skin.

  • I had my stroke in 2010 in Hong Kong and was looked after in a private Chinese hospital.
  • They were very strict and measured all the bodily fluids, that I passed.
  • They didn’t collect any urine, so they accused me of throwing all my water away.
  • I was not guilty, as I was drinking it all.

So they fitted me with a catheter and guess what? They still didn’t collect anything.

It was evidence that my skin is not good at holding water.

So why do I want to measure the blood pressure at my ankle? Or in fact both ankles.

In my ICI days in the 1960s and 1970s, I was helping chemical engineers to understand chemical plants and reactions, by looking at flows and pressures in the various pipes of the plant or experimental rig.

But I do wonder, if the red nature of my left foot, is due to some sort of irregularity in the blood flow to my left leg.

Berkeley Scientists Finally Solve 10-Year Puzzle Enabling Efficient CO2-to-Fuel Conversion With Major Climate Impact Potential

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

This is the sub-heading.

In a groundbreaking advancement, scientists at Lawrence Berkeley National Laboratory and SLAC National Accelerator Laboratory have unveiled the critical mechanisms behind the degradation of copper catalysts, a revelation that promises to revolutionize the production of sustainable fuels by enhancing the efficiency and stability of CO2 conversion processes.

This paragraph gives more details.

Scientists from the Lawrence Berkeley National Laboratory and SLAC National Accelerator Laboratory have made a groundbreaking discovery in the field of artificial photosynthesis. By utilizing advanced X-ray techniques, they have uncovered the critical factors that limit the performance of copper catalysts in converting carbon dioxide and water into useful fuels. This revolutionary insight could significantly enhance the stability and efficiency of catalysts in CO2 conversion processes, potentially accelerating the production of ethanol and ethylene. The research, which tackles a decades-old puzzle, offers promising avenues for the development of more durable catalyst systems, paving the way for future advancements in sustainable energy solutions.

I first came across catalysts in my working life, when I was working at ICI. I was modelling a chemical process called sulphonation for a guy who was trying to find an efficient way to create the monomer of building block for a new engineering plastic.

Some feel that all plastics are bad for the environment, but I think that, if the plastic is designed to replace another material in a long-lasting application, then plastic is good for the environment.

This picture shows my wonderful Sheba cutlery.

A Box Full Of Sheba Cutlery

Note.

  1. C and I bought it in the 1960s, when we got married.
  2. Some have been used every day for over fifty years.
  3. The important bits are Sheffield stainless steel, with the handles formed of black Delrin plastic.
  4. Some of the handles have been in the dishwasher too many times and have faded.
  5. From what I have seen on the Internet, the average worth of pieces could be as much as a tenner.

Perhaps, when I pass on, all the pieces should be divided between my grandchildren.

I have digressed and I will return to my modelling project with one of ICI’s catalyst experts.

I remember him telling me, that if you could improve the way catalysts worked, you would open up whole new areas of chemistry.

It looks to me, that the scientists at Berkeley may have opened up a route to turn carbon dioxide into fuel.

Whether that is a good route to decarbonisation is another long discussion.

Did Hydrogen Lose Labour The Runcorn And Helsby By-Election

I used to work in the Castner-Kellner works at ICI Runcorn, where hydrogen is produced using electrolysis in the Castner-Kellner process.

That process used a lot of mercury and wasn’t good for the health of the workforce. One of my jobs was to develop instruments to detect mercury in air, blood and urine.

I believe the mercury-based process to produce chlorine, with the hydrogen as a by-product has now been replaced with a membrane-based mercury-free process.

Consider.

  • The same plant still produces a large proportion of the hydrogen we use in the UK.
  • The Runcorn plant is now owned by INEOS, which in turn is owned by tax-exile and Brexiteer ; Jim Ratcliffe.
  • I doubt, Mr. Ratcliffe is a supporter of the Labour Party.
  • The big promoters of hydrogen are the Bamfords and their companies ; JCB, Ryse and Wrightbus, who are not considered companies that Labour would support.
  • Although, Wrightbus seem to have had some political support lately.
  • Google AI can’t find any details on Reform UK’s or Nigel Farage’s views on hydrogen.
  • Ed Miliband hasn’t shown himself to be very knowledgeable about hydrogen.
  • This article on the BBC is entitled Ellesmere Port Hydrogen Heating Trial Scrapped After Protests.

It strikes me, that if one candidate had got a grip on the hydrogen issue, then there would have been a different result in the by-election.

Backing Up The Wind With The Keadby Power Stations

I went to Cleethorpes from Doncaster by train yesterday. You pass the Keadby site, where there are two large gas–fired power stations of 734 MW and 710 MW. A third one ; Keadby 3 of 910 MW complete with carbon capture and storage should join them by 2027.

So that will be nearly 2.5 GW of reliable electricity.

I find it interesting that one of our first gas-fired power stations with carbon capture will be in Lincolnshire, which is famous for growing plants of all shapes, types and sizes. So will we be seeing lots of greenhouses on the flat lands I saw yesterday, growing plants in an atmosphere they like, so that we can generate our carbon dioxide and eat it.

 

The next power station at Keadby is called the Keadby Next Generation power station, which is intended to be complete by 2030. It is a bit of a puzzle in that it will run on up to 1800 MW of hydrogen and only produce up to 910 MW of electricity.

Note.

  1. The hydrogen will come from SSE’s hydrogen store at Aldbrough and Centrica’s store at Rough.
  2. Surely, the amount of hydrogen and electricity should balance.

When I worked in ICI’s hydrogen plant in the 1960s, ICI had no use for the hydrogen, so they sent it to their power station, blended it with coal gas and used it to make steam for other processes.

Could Keadby Next Generation power station be providing zero-carbon steam for the chemical and other processes on Humberside?

Adding the 910 MW of electricity to Keadby’s gas-fired total of 2.5 GW gives 3.4 GW of electricity from Keadby to back up the wind farms.

3.4 GW at Keadby is what I call backup!

It also should be noted, that one of the reasons for building the Mersey Tidal Barrage is to provide backup for all the wind farms in Liverpool Bay.

Conclusion

I believe that SSE could be supplying zero-carbon steam in addition to electricity from the Keadby Hydrogen power station.

UK Government Sets 8-Hour Minimum For LDES Cap-And-Floor Sheme

The title of this post, is the sa,e as that of this article on Energy Storage News.

This is the sub-heading.

The UK government has published a Technical Decision Document confirming crucial aspects of its long duration electricity storage (LDES) cap-and-floor scheme, which includes increasing the minimum duration required from six hours to eight

These paragraphs give full details.

The document, released by regulator Ofgem on 11 March, details the final overarching rules and requirements for the scheme as well as how it will be implemented, though significant detail still remains to be worked out.

The scheme will provide a cap-and-floor revenue protection for 20-25 years that will allow all capital costs to be recoverable, and is effectively a subsidy for LDES projects that may not be commercially viable without it. Most energy storage projects being deployed in the UK today are lithium-ion battery energy storage systems (BESS) of somewhere between 1-hour and 3-hour in duration (very occasionally higher).

One of the most significant new details of the scheme is that, following industry feedback, the minimum duration for projects to qualify has been increased from six hours to eight hours of continuous rated power.

The ‘continuous rated power’ aspect prevents shorter duration projects from bidding in a smaller section of their MW capacity in order to act like an 8-hour system.

Another interesting detail pointed out by several commentators is that the cap is a ‘soft’ one, meaning it will allow extra revenue to be shared between developers and consumers. Exact details on the ratio are yet to be determined.

As a Graduate Control Engineer from Liverpool University in the 1960s, I hope that the move from a six to eight hours  minimum duration is feasible.

I wasn’t dealing with power systems, but with multi-vessel chemical plants.

These are my thoughts.

The biggest project, I was dealing with a few years later in the 1970s, was the modeling of all the the reservoirs and pipelines by the Water Resoures Board.

As the supply side of the water industry hasn’t had too many issues with the volume of water supplied, I feel that the main modelers must have done a reasonable job.

Six To Eight Hours Of Continuous Operation

The article says this about uprating from six to eight hours of continuous operations.

All the systems that have been proposed for cap-and-floor operation, seem to have some form of physical storage.

  • Energy Dome appears to have tents of carbon dioxide.
  • Energy Vault uses stacks of heavy weights.
  • Form Energy has tanks of rust.
  • Gravitricity has huge weights in disued mine shafts.
  • Highview Power has large tanks of liquid air.
  • Pumped storage hydro has two lakes, that hold water.
  • Rheenergise has two large tanks, of a  water-based slurry.

So to go from six to eight hours will hopefully just need some more storage.

Highview Power appears to use similar gas tanks to those used to store natural gas or hydrogen.

This image clipped from Highview’s web site, shows large tanks for liquified gas storage.

With tanks like these, which can hold GW-equivalents of liquid air, Highview could be building batteries with storage to rival the smaller pumped storage hydroelectric power stations. They are already talking of 200 MW/2.5 GWh systems, which would have a 12.5 hour continuous rating and would probably need two to three tanks.

Coire Glas Pumped Storage

I’ll use Coire Glas pumped storage hydro electric power station as an example.

As currently planned SSE’s Cioire Glas  pumped storage hydroelectric power station is 1.5 GW/30 GWh, so it has a a 20 hour continuous rating.

In The UK’s Pumped Storage Hydroelectricity, I gave a rough estimate of the pumped storage hydroelectricity systems in operation or planed as nearly 11 GW/224GWh.

The Soft Cap

The article says this about a soft cap.

Another interesting detail pointed out by several commentators is that the cap is a ‘soft’ one, meaning it will allow extra revenue to be shared between developers and consumers. Exact details on the ratio are yet to be determined.

I seem to remember that when I was modeling a larger multi-vessel chemical plant at ICI, I was using sharing between vessels, to get the system to operate on a PACE-231R analog computer.

So I suspect a soft cap is possible.
