Funding Awarded For Study On Hydrogen Storage Potential In North Yorkshire

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

This is the sub-heading.

A new study has been awarded funding to explore the potential for underground hydrogen storage near the Knapton power plant, North Yorkshire.

These two paragraphs add more details.

Knapton H2 Storage is a consortium led by gas distributor Northern Gas Networks and partnered with BGS, Centrica Energy Storage+, Third Energy Onshore and the University of Edinburgh. The consortium has been awarded ‘Discovery’ funding by Ofgem’s Strategic Innovation Fund (SIF) to undertake a new study to evaluate geological storage potential in the Knapton area, North Yorkshire. The Ofgem SIF funding is designed to drive innovation in energy networks as part of the ‘Revenue = incentives + innovation + outputs’ (RIIO-2) price control for gas and electricity networks.

Energy storage and backup power will become increasingly important as the UK increases the amount of renewable energy supplying electricity. This study is the first of its kind in the region and will undertake a feasibility assessment of the area’s geology to host energy storage technologies, allowing for the decarbonisation of adjacent gas-fired peaking power plants (those that only run when there is high demand) such as that at Knapton.

Note.

  1. The Wikipedia entry for East Knapton has sections on both Knapton Generating Station and the Ryedale Gas Fields.
  2. Production of gas from the Ryedale Gas Fields was suspended in 2020.

This is the last paragraph about the Knapton generating station.

Knapton Generating Station was taken offline in 2019 and was subsequently dismantled. There are plans to install a 56 MWh battery on the site.

It looks like depending on the results of the study, Knapton H2 Storage will have plans for the Knapton Generating station site.

How Will The UK Power All These Proposed Data Centres?

On Wednesday, a cardiologist friend asked me if we have enough power to do Trump’s UK AI, so I felt this post might be a good idea.

Artificial Intelligence Gave This Answer

I first asked Google AI, the title of this post and received this reply.

The UK will power proposed data centres using a mix of grid-supplied low-carbon electricity from sources like offshore wind and through on-site renewable generation, such as rooftop solar panels. Data centre operators are also exploring behind-the-meter options, including battery storage and potential future nuclear power, to meet their significant and growing energy demands. However, the UK’s grid infrastructure and high energy prices present challenges, with industry calls for grid reform and inclusion in energy-intensive industry support schemes to facilitate sustainable growth.

Google also pointed me at the article on the BBC, which is entitled Data Centres To Be Expanded Across UK As Concerns Mount.

This is the sub-heading.

The number of data centres in the UK is set to increase by almost a fifth, according to figures shared with BBC News.

These are the first three paragraphs.

Data centres are giant warehouses full of powerful computers used to run digital services from movie streaming to online banking – there are currently an estimated 477 of them in the UK.

Construction researchers Barbour ABI have analysed planning documents and say that number is set to jump by almost 100, as the growth in artificial intelligence (AI) increases the need for processing power.

The majority are due to be built in the next five years. However, there are concerns about the huge amount of energy and water the new data centres will consume.

Where Are The Data Centres To Be Built?

The BBC article gives this summary of the locations.

More than half of the new data centres would be in London and neighbouring counties.

Many are privately funded by US tech giants such as Google and Microsoft and major investment firms.

A further nine are planned in Wales, one in Scotland, five in Greater Manchester and a handful in other parts of the UK, the data shows.

While the new data centres are mostly due for completion by 2030, the biggest single one planned would come later – a £10bn AI data centre in Blyth, near Newcastle, for the American private investment and wealth management company Blackstone Group.

It would involve building 10 giant buildings covering 540,000 square metres – the size of several large shopping centres – on the site of the former Blyth Power Station.

Work is set to begin in 2031 and last for more than three years.

Microsoft is planning four new data centres in the UK at a total cost of £330m, with an estimated completion between 2027 and 2029 – two in the Leeds area, one near Newport in Wales, and a five-storey site in Acton, north-west London.

And Google is building a data centre in Hertfordshire, an investment worth £740m, which it says will use air to cool its servers rather than water.

There is a map of the UK, with dots showing data centres everywhere.

One will certainly be coming to a suitable space near you.

Concerns Over Energy Needs

These three paragraphs from the BBC article, talk about the concerns about energy needs.

According to the National Energy System Operator, NESO, the projected growth of data centres in Great Britain could “add up to 71 TWh of electricity demand” in the next 25 years, which it says redoubles the need for clean power – such as offshore wind.

Bruce Owen, regional president of data centre operator Equinix, said the UK’s high energy costs, as well as concerns around lengthy planning processes, were prompting some operators to consider building elsewhere.

“If I want to build a new data centre here within the UK, we’re talking five to seven years before I even have planning permission or access to power in order to do that,” he told BBC Radio 4’s Today programme.

But in Renewable Power By 2030 In The UK, I calculated that by 2030 we will add these yearly additions of offshore wind power.

  • 2025 – 1,235 MW
  • 2026 – 4,807 MW
  • 2027 – 5,350 MW
  • 2028 – 4,998 MW
  • 2029 – 9,631 MW
  • 2030 – 15,263 MW

Note.

  1. I have used pessimistic dates.
  2. There are likely to be more announcements of offshore wind power in the sea around the UK, in the coming months.
  3. As an example in Cerulean Winds Submits 1 GW Aspen Offshore Wind Project In Scotland (UK), I talk about 3 GW of offshore wind, that is not included in my yearly totals.
  4. The yearly totals add up to a total of 58,897 MW.

For solar power, I just asked Google AI and received this answer.

The UK government aims to have between 45 and 47 gigawatts (GW) of solar power capacity by 2030. This goal is set out in the Solar Roadmap and aims to reduce energy bills and support the UK’s clean power objectives. The roadmap includes measures like installing solar on new homes and buildings, exploring solar carports, and improving access to rooftop solar for renters.

Let’s assume that we only achieve the lowest value of 45 GW.

But that will still give us at least 100 GW of renewable zero-carbon power.

What will happen if the wind doesn’t blow and the sun doesn’t shine?

I have also written about nuclear developments, that were announced during Trump’s visit.

This is an impressive array of nuclear power, that should be able to fill in most of the weather-induced gaps.

In Renewable Power By 2030 In The UK, I also summarise energy storage.

For pumped storage hydro, I asked Google AI and received this answer.

The UK’s pumped storage hydro (PSH) capacity is projected to more than double by 2030, with six projects in Scotland, including Coire Glas and Cruachan 2, potentially increasing capacity to around 7.7 GW from the current approximately 3 GW. This would be a significant step towards meeting the National Grid’s required 13 GW of new energy storage by 2030, though achieving this depends on policy support and investment.

There will also be smaller lithium-ion batteries and long duration energy storage from companies like Highview Power.

But I believe there will be another source of energy that will ensure that the UK achieves energy security.

SSE’s Next Generation Power Stations

So far two of these power stations have been proposed.

  • Keadby will be 900 MW and has this web site.
  • Ferrybridge will be 1200 MW and has this web site.

Note.

  1. Both power stations are being designed so they can run on natural gas, 100 % hydrogen or a blend of natural gas and hydrogen.
  2. Keadby will share a site with three natural gas-powered power stations and be connected to the hydrogen storage at Aldbrough, so both fuels will be available.
  3. Ferrybridge will be the first gas/hydrogen power station on the Ferrybridge site and will have its own natural gas connection.
  4. How Ferrybridge will receive hydrogen has still to be decided.
  5. In Hydrogen Milestone: UK’s First Hydrogen-to-Power Trial At Brigg Energy Park, I describe how Centrica tested Brigg gas-fired power station on a hydrogen blend.
  6. The power stations will initially run on natural gas and then gradually switch over to lower carbon fuels, once delivery of the hydrogen has been solved for each site.

On Thursday, I went to see SSE’s consultation at Knottingley for the Ferrybridge power station, which I wrote about in Visiting The Consultation For Ferrybridge Next Generation Power Station At Knottingley.

In the related post, I proposed using special trains to deliver the hydrogen from where it is produced to where it is needed.

Could HiiROC Be Used At Ferrybridge?

Consider.

  • HiiROC use a process called thermal plasma electrolysis to split any hydrocarbon gas into hydrogen and carbon black.
  • Typical input gases are chemical plant off gas, biomethane and natural gas.
  • Carbon black has uses in manufacturing and agriculture.
  • HiiROC uses less energy than traditional electrolysis.
  • There is an independent power source at Ferrybridge from burning waste, which could be used to ower a HiiROC  system to generate the hydrogen.

It might be possible to not have a separate hydrogen feed and still get worthwhile carbon emission savings.

Conclusion

I believe we will have enough electricity to power all the data centres, that will be built in the next few years in the UK.

Some of the new power stations, that are proposed to be built, like some of the SMRs and SSE’s Next Generation power stations could even be co-located with data centres or other high energy users.

In Nuclear Plan For Decommissioned Coal Power Station, I describe how at the former site of Cottam coal-fired power station, it is proposed that two Holtec SMR-300 SMRs will be installed to power advanced data centres. If the locals are objecting to nuclear stations, I’m sure that an SSE Next Generation power station, that was burning clean hydrogen, would be more acceptable.

Raft Of US-UK Nuclear Deals Ahead Of Trump Visit

The title of this post, is the same as that of this article on World Nuclear News.The article is a good summary of all the deals done between the US and UK governments concerning next-generation nuclear power.

This is the introduction.

Several agreements have been signed between UK and US companies to advance the deployment of small modular reactors and advanced reactors in both countries. The deals were signed ahead of the state visit of President Donald Trump to the UK later this week.

The whole article is a must-read.

These are my posts, that are related to the main agreement.

I shall finish it later.

Hydrogen Milestone: UK’s First Hydrogen-to-Power Trial At Brigg Energy Park

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

This is the sub-heading.

Centrica and HiiROC, supported by the Net Zero Technology Centre (NZTC), have successfully demonstrated the injection of hydrogen into a gas-fired peak power plant at Centrica’s Brigg Energy Park, North Lincolnshire. The trial that took place last Thursday (11 September) marks a UK first in using hydrogen to decarbonise peak power generation supplying power directly to the electricity grid.

These three opening paragraphs add detail.

HiiROC’s modular hydrogen production technology, using Thermal Plasma Electrolysis (TPE), produced hydrogen on site which was then blended at a 3% ratio for the purposes of a one-hour trial.

The trial marks a further step forward in Centrica’s ongoing efforts to advance innovative solutions for the decarbonisation of its portfolio of gas plants, demonstrating that existing gas infrastructure can operate on a hydrogen blend to provide reliable, low carbon electricity to UK homes and businesses. More broadly, the trial shows a viable route for delivering on decarbonisation readiness obligations for peaker generation as part of the UK’s journey to net zero.

It is also a key milestone in HiiROC’s journey, demonstrating the effectiveness and affordability of HiiROC’s TPE process, which produces hydrogen without CO2 emissions, making it compliant with the UK’s Low Carbon Hydrogen Standard (LCHS). By leveraging the existing gas network and co-locating hydrogen production where it is needed, operators can decarbonise without costly new infrastructure.

Note.

  1. This test was only at a low level of hydrogen.
  2. Brigg power station is a 240 MW power station, which is fuelled by natural gas.

A long journey starts with a single step.

Centrica And X-energy Agree To Deploy UK’s First Advanced Modular Reactors

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

This is the sub-heading.

Centrica and X-Energy, LLC, a wholly-owned subsidiary of X-Energy Reactor Company, LLC, today announced their entry into a Joint Development Agreement (JDA) to deploy X-energy’s Xe-100 Advanced Modular Reactors (“AMR”) in the United Kingdom.

These three paragraphs add more details.

The companies have identified EDF and Centrica’s Hartlepool site as the preferred first site for a planned U.K. fleet of up to 6 gigawatts.

The agreement represents the first stage in a new trans-Atlantic alliance which could ultimately mobilise at least £40 billion in economic value to bring clean, safe and affordable power to thousands of homes and industries across the country and substantive work for the domestic and global supply chain.

A 12-unit Xe-100 deployment at Hartlepool could add up to 960 megawatts (“MW”) of new capacity, enough clean power for 1.5 million homes and over £12 billion in lifetime economic value. It would be developed at a site adjacent to Hartlepool’s existing nuclear power station which is currently scheduled to cease generating electricity in 2028. Following its decommissioning, new reactors would accelerate opportunities for the site and its skilled workforce. The site is already designated for new nuclear under the Government’s National Policy Statement and a new plant would also play a critical role in generating high-temperature heat that could support Teesside’s heavy industries.

This is no toe-in-the-water project, but a bold deployment of a fleet of small modular reactors to provide the power for the North-East of England for the foreseeable future.

These are my thoughts.

The Reactor Design

The Wikipedia entry for X-energy has a section called Reactor Design, where this is said.

The Xe-100 is a proposed pebble bed high-temperature gas-cooled nuclear reactor design that is planned to be smaller, simpler and safer when compared to conventional nuclear designs. Pebble bed high temperature gas-cooled reactors were first proposed in 1944. Each reactor is planned to generate 200 MWt and approximately 76 MWe. The fuel for the Xe-100 is a spherical fuel element, or pebble, that utilizes the tristructural isotropic (TRISO) particle nuclear fuel design, with high-assay LEU (HALEU) uranium fuel enriched to 20%, to allow for longer periods between refueling. X-energy claims that TRISO fuel will make nuclear meltdowns virtually impossible.

Note.

  1. It is not a conventional design.
  2. Each reactor is only about 76 MW.
  3. This fits with “12-unit Xe-100 deployment at Hartlepool could add up to 960 megawatts (“MW”) of new capacity” in the Centrica press release.
  4. The 960 MW proposed for Hartlepool is roughly twice the size of the Rolls-Rpoyce SMR, which is 470 MW .
  5. Safety seems to be at the forefront of the design.
  6. I would assume, that the modular nature of the design, makes expansion easier.

I have no reason to believe that it is not a well-designed reactor.

Will Hartlepool Be The First Site?

No!

This page on the X-energy web site, describes their site in Texas, which appears will be a 320 MW power station providing power for Dow’s large site.

There appear to be similarities between the Texas and Hartlepool sites.

  • Both are supporting industry clustered close to the power station.
  • Both power stations appear to be supplying heat as well as electricity, which is common practice on large industrial sites.
  • Both use a fleet of small modular reactors.

But Hartlepool will use twelve reactors, as opposed to the four in Texas.

How Will The New Power Station Compare With The Current Hartlepool Nuclear Power Station?

Consider.

  • The current Hartlepool nuclear power station has two units with a total capacity of 1,185 MW.
  • The proposed Hartlepool nuclear power station will have twelve units with a total capacity of 960 MW.
  • My instinct as a Control Engineer gives me the feeling, that more units means higher reliability.
  • I suspect that offshore wind will make up the difference between the power output of the current and proposed power stations.

As the current Hartlepool nuclear power station is effectively being replaced with a slightly smaller station new station, if they get the project management right, it could be a painless exercise.

Will This Be The First Of Several Projects?

The press release has this paragraph.

Centrica will provide initial project capital for development with the goal of initiating full-scale activities in 2026. Subject to regulatory approval, the first electricity generation would be expected in the mid-2030s. Centrica and X-energy are already in discussions with additional potential equity partners, as well as leading global engineering and construction companies, with the goal of establishing a UK-based development company to develop this first and subsequent projects.

This approach is very similar to the approach being taken by Rolls-Royce for their small modular reactors.

Will Centrica Use An X-energy Fleet Of Advanced Modular Reactors At The Grain LNG Terminal?

This press release from Centrica is entitled Investment In Grain LNG Terminal.

This is one of the key highlights of the press release.

Opportunities for efficiencies to create additional near-term value, and future development options including a combined heat and power plant, bunkering, hydrogen and ammonia.

Note.

  1. Bunkering would be provided for ships powered by LNG, hydrogen or ammonia.
  2. Heat would be needed from the combined heat and power plant to gasify the LNG.
  3. Power would be needed from the combined heat and power plant to generate the hydrogen and ammonia and compress and/or liquify gases.

Currently, the heat and power is provided by the 1,275 MW Grain CHP gas-fired power station, but a new nuclear power station would help to decarbonise the terminal.

Replacement Of Heysham 1 Nuclear Power Station

Heysham 1 nuclear power station is part-owned by Centrica and EdF, as is Hartlepool nuclear power station.

Heysham 1 nuclear power station is a 3,000 MW nuclear power station, which is due to be decommissioned in 2028.

I don’t see why this power station can’t be replaced in the same manner as Hartlepool nuclear power station.

Replacement Of Heysham 2 Nuclear Power Station

Heysham 2 nuclear power station is part-owned by Centrica and EdF, as is Hartlepool nuclear power station.

Heysham 2 nuclear power station is a 3,100 MW nuclear power station, which is due to be decommissioned in 2030.

I don’t see why this power station can’t be replaced in the same manner as Hartlepool nuclear power station.

Replacement Of Torness Nuclear Power Station

Torness nuclear power station is part-owned by Centrica and EdF, as is Hartlepool nuclear power station.

Torness nuclear power station is a 1,290 MW nuclear power station, which is due to be decommissioned in 2030.

I don’t see why this power station can’t be replaced in the same manner as Hartlepool nuclear power station.

But the Scottish Nationalist Party may have other ideas?

What Would Be The Size Of Centrica’s And X-energy’s Fleet Of Advanced Modular Reactors?

Suppose.

  • Hartlepool, Grain CHP and Torness power stations were to be replaced by identical 960 MW ADRs.
  • Heysham 1 and Heysham 2 power stations were to be replaced by identical 1,500 MW ADRs.

This would give a total fleet size of 5,880 MW.

A paragraph in Centrica’s press release says this.

The companies have identified EDF and Centrica’s Hartlepool site as the preferred first site for a planned U.K. fleet of up to 6 gigawatts.

This fleet is only 120 MW short.

I’m Getting A New Hydrogen-Ready Boiler

The pump in my current nine-year-old boiler has died and it needs to be replaced.

The plumber gave me two solutions.

  • Put a new pump in the old boiler.
  • Replace the boiler with the current version of the old boiler.

Note.

  1. The plumber said the new boiler would be hydrogen-ready.
  2. I seem to remember the same pump failed before.
  3. The pump had failed because of a water-leak into its electrics.
  4. Was the previous failure of the pump caused by the same water-leak?
  5. Fitting a heat pump in my house would probably cost more than I could afford.
  6. The new boiler would come with a ten-year guarantee.

As an engineer, I can see the following scenarios for heating my house and providing hot water.

1. Keeping Calm And Carrying On

This means that the current arrangements for energy continue.

  • There would be no compulsory heat pumps.
  • There would be no change to any of my hardware, after installing the new boiler.
  • I would continue to get gas for heating and hot water  delivered through the mains.

The new boiler solution should give me ten years of reasonably trouble free-running, so long as the gas was natural gas, hydrogen blend or hydrogen.

2. Keeping Calm And Carrying On But My Energy Supplier Switches My Gas To 20 % Hydrogen-Blend

This means that the current arrangements for energy continue.

  • There would be no compulsory heat pumps.
  • There would be no change to any of my hardware, after installing the new boiler.
  • I would continue to get gas for heating and hot water  delivered through the mains.
  • The gas pipe into my house would have to be checked for compatibility with hydrogen-blend. But then I encountered no problems when switched from coal-gas to North Sea Gas around 1970.

The new boiler solution should give me ten years of reasonably trouble free-running, so long as the gas was natural gas, hydrogen-blend or hydrogen.

3. Keeping Calm And Carrying On But My Energy Supplier Switches My Gas To 100 % Hydrogen

This means that the current arrangements for energy continue.

  • There would be no compulsory heat pumps.
  • There would be no change to any of my hardware, after installing the new boiler.
  • I would continue to get gas for heating and hot water  delivered through the mains.
  • The gas pipe into my house would have to be checked for compatibility with hydrogen.

The new boiler solution should give me ten years of reasonably trouble free-running, so long as the gas was natural gas, hydrogen blend or hydrogen.

4. Switching To Some Form Of Heat Pump

  • This would mean that I would go all electric.
  • My house is a concrete lump and a guy I trust, said it would be difficult to fit a heat pump.
  • I am suspicious of scientific and technical solutions proposed by politicians.

I’m not saying, I’d never use a heat pump, but I will take a lot of convincing.

5. Switching To Some New Form Of Electric Heating

I have seen two companies, which use the excess heat from a data centre to heat water for central heating and/or hot water for domestic needs.

  • heata is a spin out from Centrica, that provides hot water and saves you money on your utility bill.
  • thermify is a startup from Wales, that replaces the gas boiler, with an electric one.

There are probably other similar systems under development.

From my knowledge of computing and electrical engineering, I believe devices like this could be new form of cost-efficient electric heating.

Because my house has three-bedrooms, I would need a thermify, for both heating and hot water, but a heata working in tandem with my gas boiler could probably keep me in hot water.

I would feel that large blocks of flats or offices could have a data centre in the basement to provide heat for the building.

I would also suspect, that there are other devices out there, that work on different principles.

My Decision

I’m fitting a new boiler, as that should give me ten years’guarantee-backed and trouble free running and future-proof me for all possible government decisions, except saying that everybody must fit a heat pump.

When, this new boiler pops its clogs, i would hope, that some clever engineers have come up with a plug-compatible electric replacement for the new boiler I am about to have fitted.

Scotland And AquaVentus Partner On North Sea Hydrogen Pipeline Plans

The title of this post, is the same as that of this article on H2-View.

These four paragraphs introduce the deal and add some detail.

Hydrogen Scotland has committed to working with the AquaDuctus consortium on cross-border infrastructure concepts to connect Scotland’s offshore wind power to hydrogen production in the North Sea.

Under a Memorandum of Understanding (MOU), the two organisations plan to combine Scotland’s offshore wind with AquaVentus’ offshore electrolysis expertise, linking export and import goals across the North Sea.

The AquaDuctus pipeline is a planned offshore hydrogen link designed to carry green hydrogen through the North Sea, using a pipes and wires hybrid approach. The German consortium plans 10GW of offshore electrolysers in the North Sea, producing around one million tonnes of green hydrogen.

The pipeline design allows offshore wind farms to deliver electricity when the grid needs it, or convert power into hydrogen via electrolysis and transport it through pipelines.

Germany is embracing hydrogen in a big way.

  • I introduce AquaVentus in AquaVentus, which I suggest you read.
  • AquaVentus is being developed by RWE.
  • AquaVentus connects to a German hydrogen network called H2ercules to actually distribute the hydrogen.

This video shows the structure of AquaVentus.

I clipped this map from the video.

Note.

  1. The thick white line running North-West/South-East is the spine of AquaVentus, that will deliver hydrogen to Germany.
  2. There is a link to Esbjerg in Denmark, that is marked DK.
  3. There appears to be an undeveloped link to Norway, which goes North,
  4. There appears to be an undeveloped  link to Peterhead in Scotland, that is marked UK.
  5. There appears to be a link to just North of the Humber in England, that is marked UK.
  6. Just North of the Humber are the two massive gas storage sites of Aldbrough owned by SSE and Rough owned by Centrica.
  7. Aldbrough and Rough gas storage sites are being converted into two of the largest hydrogen storage sites in the world!
  8. There appear to be small ships sailing up and down the East Coast of the UK. Are these small coastal tankers, that are distributing the hydrogen to where it is needed?

When it is completed, AquaVentus will be a very comprehensive hydrogen network.

I believe that offshore electrolysers could be built in the area of the Hornsea 4, Dogger Bank South and other wind farms and the hydrogen generated would be taken by AquaVentus to either Germany or the UK.

  • Both countries get the hydrogen they need.
  • Excess hydrogen would be stored in Aldbrough and Rough.
  • British Steel at Scunthorpe gets decarbonised.
  • A 1.8 GW hydrogen-fired powerstation at Keadby gets the hydrogen it needs to backup the wind farms.

Germany and the UK get security in the supply of hydrogen.

Conclusion

This should be a massive deal for Germany and the UK.

Powering The Humber Energy Revolution

The title of this post is the same as this story on the Centrica web site.

This is the sub-heading.

From the UK’s largest industrial carbon emitter to a clean energy powerhouse, the Humber is ready to be transformed.

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

We’re prepared to invest £2 billion to keep Rough open and transform it into one of the world’s largest hydrogen storage facilities. This bold move is vital for the UK’s energy security, accelerating the energy transition and unlocking thousands of green jobs. But to make this vision a reality, we need strategic support from government.

We’ve spent time in the Humber, speaking with local communities and industry leaders to understand how this region’s infrastructure shapes lives and powers the nation.

It looks to me, that Centrica have got fed up with our useless, squabbling politicians and decided to act.

There is also a video to watch.

Shell Pulls Plug On Rotterdam Biofuels Plant

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

This is the sub-heading.

Retreat from green energy continues as facility that was earmarked to produce sustainable aviation fuel and renewable diesel will not now be built

These first three paragraphs add some details.

Shell has scrapped construction of one of Europe’s biggest biofuels plants as it continues its retreat from green energy

The move by the FTSE 100 oil and gas group represents a further setback for efforts to cut aviation emissions.

Shell said it would not restart construction of the biofuels facility at its Rotterdam energy and chemicals plant, which was due to produce sustainable aviation fuel (SAF) and renewable diesel.

When I wrote Centrica Secures Investment Stake In Gasrec Helping Boost UK Bio-LNG Ambitions, I took a look at the use of liquified natural gas (LNG) in transport.

This paragraph from the Centrica press release about the stake, gives the thoughts of Chris O’Shea, who is Group Chief Executive, Centrica.

Chris O’Shea, Group Chief Executive, Centrica plc, said: “Demand for bio-LNG for transport is growing fast as more HGV operators make the switch – drawn by a clean, ready-to-use fuel which slashes CO2 emissions by up to 85 per cent in comparison to diesel*. This investment in Gasrec enhances our collaboration with the leading company in the sector, and puts us in a strong position to energise a vital sector of the industry on its journey to net zero.”

Chris O’Shea of Centrica appears to feel that bio-LNG is a good alternative to diesel, so have Shell come to a similar decision, about satisfying the demand for diesel?

I asked Google AI if LNG has advantages over diesel as a truck fuel and received this answer.

Yes, LNG offers advantages over diesel, including significantly lower emissions of nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter (PM), which improves local air quality. It can also be more economically efficient, with fuel costs potentially lower than diesel depending on market conditions. However, the overall greenhouse gas (GHG) benefits are mixed; while LNG has a lower carbon content, it can result in higher lifecycle GHG emissions due to energy losses in its production and transport, as well as methane slip.

Note.

  1. If it drops emissions by up to 85 percent for bio-LNG, surely, it would do the same for LNG.
  2. I also think with tight regulations, the use of LNG could improve air quality in cities like London.
  3. LNG would probably be a more affordable fuel than hydrogen.

It should also be noted, that several major diesel engine makers, now make families of engines, which can handle, diesel, hydrogen and natural gas.

LNG would also be a convenient stepping stone between current fuels and hydrogen, that might give a few extra years for the transition.

Could LNG Be Used In Aircraft?

Consider.

  • LNG would certainly give some reduction in carbon emissions.
  • Handling LNG in aircraft could have similar problems to hydrogen, so companies like Airbus might have already solved them.
  • In addition, LNG doesn’t have the fearsome reputation, that hydrogen seems to have gained because of the Hindenburg.
  • It would be easier to provide LNG fuel at airports all round the world.
  • Airbus have said availability of hydrogen at airports, could be a problem.

Out of curiosity, I asked Google AI if LNG could be used to power an airliner and received this answer.

Yes, liquefied natural gas (LNG) can theoretically be used to power airliners, offering a potential reduction in CO2 emissions compared to conventional jet fuel, but significant challenges exist. These challenges include the need for entirely new, larger, and heavier cryogenic fuel tanks, modifications to aircraft engines and fuel systems, and the development of a new global infrastructure for LNG supply. While experimental tests have been conducted, such as on the Soviet Union’s Tupolev Tu-155 in 1989, LNG is not currently in normal service due to these practical and infrastructural hurdles.

I would prefer it was a purpose-designed Airbus, than a Soviet-era Tupolev.

Centrica Secures Investment Stake In Gasrec Helping Boost UK Bio-LNG Ambitions

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

This is the sub-heading.

Centrica has secured a minority stake in Gasrec, the UK’s largest dual provider of bio-LNG (bio-Liquified Natural Gas) and bio-CNG (bio-Compressed Natural Gas) to the road transport sector,

These first two paragraphs give more details.

Gasrec says the investment will drive the next phase of its infrastructure ambitions, with plans to open a UK wide network of open-access refuelling stations supplying renewable bio-LNG for the decarbonisation of heavy goods vehicles.

Centrica is taking a 16% stake and becomes one of three major shareholders in Gasrec, alongside global integrated energy company bp and private family office 44 North.

I have some thoughts.

Does Running A Truck On bio-LNG or bio-CNG. Reduce Carbon Emissions?

This paragraph from the press release, gives the thoughts of Chris O’Shea, who is Group Chief Executive, Centrica.

Chris O’Shea, Group Chief Executive, Centrica plc, said: “Demand for bio-LNG for transport is growing fast as more HGV operators make the switch – drawn by a clean, ready-to-use fuel which slashes CO2 emissions by up to 85 per cent in comparison to diesel*. This investment in Gasrec enhances our collaboration with the leading company in the sector, and puts us in a strong position to energise a vital sector of the industry on its journey to net zero.”

As Centrica is a public company, with shareholders, who would take a dim view of Mr. O’Shea telling porkies, I suspect we can assume that the following is true.

Drawn by a clean, ready-to-use fuel which slashes CO2 emissions by up to 85 per cent in comparison to diesel.

The asterisk in the full quote, refers to this note.

Low Carbon Vehicle Partnership, Innovate UK and Office for Low Emission Vehicles, Low Emission Freight & Logistics Trial (LEFT), Key Findings, November 2020. Using specific feedstocks CO2 reductions of 200% are achievable.

Centrica could be being conservative with their claims.

Decarbonising Buses, Locomotives And Trucks

Despite what Elon Musk, would have us believe, electric trucks will not dominate the future of freight transport.

An electric truck would be the vehicle equivalent of asking Usain Bolt to run a hundred metres with a large refrigerator on his back.

Trucks are going to need a fuel without a weight penalty and with a long range.

I asked Google for information about Cummins diesel, natural gas and hydrogen engines and received this AI Overview.

Cummins offers engines powered by diesel, natural gas, and hydrogen. While diesel engines are well-established, Cummins is also developing both natural gas and hydrogen engines, particularly focusing on hydrogen as a pathway to zero-carbon solutions for various applications. Cummins utilizes a fuel-agnostic platform, meaning a common base engine can be adapted for different fuel types, including diesel, natural gas, and hydrogen.

Recently, GB Railfreight purchased thirty Class 99 locomotives from Stadler.

  • They can use electrification, where it exists.
  • Where electrification doesn’t exist, they can use an onboard Cummins diesel engine, which is built in Darlington.
  • In electric-mode, they have 6.2 MW of power, and are the most powerful locomotives ever to run on UK railways.
  • In diesel-mode, they have 1.8 MW of power, which is more than enough to haul a large container train in and out of Felixstowe.

I had thought that at some future date, Cummins would convert these locomotives to electro-hydrogen.

But now that Gasrec is providing bio-LNG and bio-CNG, GB Railfreight, have the option of converting both hydrogen and biomethane.

Similar logic can be applied to Wrightbus’s Streetdeck Ultroliner, one version of which is fitted with a Cummins engine, that can be converted to electric, hydrogen or natural gas, which of course includes biomethane. This page on the Wrightbus web site describes the bus.

Wrightbus are also going back into coach manufacture, as I wrote about in Wrightbus Goes Back To The Future As It Relaunches The Contour Coach. As with the Streetdeck Ultroliner, Cummins seem to be providing one of the power units.

It seems to me, that the zero- and low-carbon revolution in transport will generate a need for the availability of biomethane, hydrogen and natural gas fuel for transport all over the country.

Gasrec with around twenty biomethane fuelling points around the country, seem well-placed to supply the biomethane in bio-LNG or bio-CNG  form.

Could Gasrec Deliver Hydrogen?

Various bus companies in the UK, have had difficulty getting the fuel for their hydrogen buses.

I believe that delivering hydrogen would be very similar to delivering LNG and if Gasrec can deliver LNG successfully and safely, they probably have the technology to do the same for hydrogen.

Centrica Seem To Be Assembling An Interesting Consortium

These are some deals, that I have reported on this blog, that involve Centrica.

Note.

  1. A lot of these deals are are about hydrogen production.
  2. Some of these deals are about biomethane production.
  3. None of these deals talk about getting hydrogen and biomethane to customers.

It appears to me, that Gasrec have a model that works to get hydrogen, methane and biomethane from production and storage to the end customers.

Developing A Rural Hydrogen Network

In Developing A Rural Hydrogen Network, I talked about supplying all those millions of off-gas grid properties with hydrogen for heating, agricultural and industrial purposes, in the countryside of the UK.

Gasrec have the technology to decarbonise the countryside.

Conclusion

Gasrec would appear to be a very useful partner for Centrica.
