Oman Set For Next Frontier In Energy Storage

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

This first paragraph introduces the story.

Oman’s solar story is already being written. Manah, Ibri II, and the next wave of solar IPPs moving through procurement have placed the Sultanate firmly among the region’s renewable leaders. The next chapter, the one every solar-rich nation is racing to author, is about the long-duration energy storage technology that powers the grid after sunset. Lithium-ion batteries handle the first few hours effectively. What comes after is the harder problem, and it is increasingly being solved by a technology called Liquid Air Energy Storage, or LAES: a technology that aligns naturally with Oman’s industrial base.

The article then describes how the technology to handle LAES technology aligns with all their expertise in handling liquified natural gas.

This paragraph outlines Oman’s expertise in cryogenic engineering.

Oman’s natural advantage in this race deserves far more attention than it has received. Cryogenic engineering, the discipline of holding substances at extraordinarily low temperatures without losing them, is the most demanding part of any LAES plant. It is also the foundation of the LNG export business that has run out of Qalhat for a quarter of a century. The workforce that liquefies natural gas at minus 162 degrees Celsius is the same workforce that can liquefy air. The insulation expertise, the compressor specifications, and the maintenance discipline are all already here, refined over decades and built locally. Few nations possess this depth of capability as a domestic resource. Oman does.

If Oman have called this one right, then any nation with plentiful renewable resources, of solar, hydro, offshore wind or geothermal, should be looking at Liquid Air Energy Storage.

This is not the first time, that Liquid Air Energy Storage has been paired with LNG.

Highview Power are the UK pioneers of Liquid Air Energy Storage and on the Projects page of their web site, there is this section on Japan.

Our investment partner Sumitomo Heavy Industries (SHI), together with Hiroshima Gas, is developing a grid‑scale LAES demonstration plant in Hatsukaichi, Hiroshima. The 5 MW, four‑hour facility will use waste cold from an adjacent LNG terminal to enhance efficiency and sustainability, showcasing the flexibility of Highview’s modular LAES technology. The plant is scheduled to be operational in 2025.

In Is Sumitomo Heavy Industries Highview Power Energy Storage System On Line At Hiroshima?, I describe how the Hiroshima plant held a completion ceremony on the 9th December, 2025.

Liquid Air Energy Storage and LNG may seem unlikely bedfellows, but when engineers share a few beers, joint projects seem to emerge.

Centrica Energy Signs Biomethane Agreement With Stream BioEnergy

The title of this post, is the same as that as this news item from Centrica.

This is the sub-heading.

Centrica Energy, in collaboration with Bord Gáis Energy, has signed an agreement with Stream BioEnergy to provide long term offtake and route-to-market services for Ireland’s largest biomethane facility processing municipal food and garden waste under development near Cork, Ireland. The plant will convert food and green waste into renewable biomethane for injection into the Irish gas grid, supporting the country’s decarbonisation goals and circular economy ambitions.

These two paragraphs add more details.

Stream BioEnergy is a leading developer of biogas plants in Ireland, and this new project represents a significant step forward in scaling sustainable gas production from organic waste. When operational in 2027, the new plant will process 90,000 tonnes per year of domestic and commercial food and garden waste to generate 80GWh annually of unsubsidised biomethane.

Under the agreement, Centrica Energy will offtake 100% of the biomethane produced at the facility and manage the associated green certificates, ensuring the renewable gas reaches end users efficiently and sustainably. The deal is supported by Bord Gáis Energy, Centrica’s Irish energy supply business, which will play a key role in enabling the delivery of biomethane to the Irish market.

It looks like Centrica are using their expertise to distribute the gas and do all the required green paperwork.

 

What Is The Major Use In Ireland Of Biomethane?

This was the obvious question to ask Google AI.

I received this answer.

The major use of biomethane in Ireland is as a renewable substitute for natural gas, primarily injected directly into the national gas grid to decarbonise the heating, industrial, and transport sectors.

While currently a developing industry (with around 75 GWh per annum produced in 2024), Ireland’s National Biomethane Strategy aims for a rapid scale-up, targeting 5.7 TWh by 2030 to meet 10% of national gas demand.

Key areas of focus include:

Grid Injection & Heating: Biomethane is injected into the gas network to decarbonise residential, commercial, and industrial heating.

Transport Fuel (Bio-CNG): It is used as a sustainable alternative to diesel for heavy-duty vehicles (HGVs) and buses, often under the Renewable Transport Fuel Obligation (RTFO).

Industrial Use: It is employed in sectors that are difficult to electrify, helping companies meet sustainability and carbon reduction goals.

Circular Economy/Agricultural Support: The production process creates a byproduct called digestate, which is used as a sustainable bio-fertiliser, helping farmers reduce reliance on chemical fertilisers.

The sector is currently shifting from relying solely on food waste to incorporating agricultural residues like slurry and grass silage.

Are Centrica Involved In Biomethane In The UK?

Out of curiosity, I had to ask Google AI this question.

I received this answer.

Yes, Centrica is actively involved in the biomethane sector in the UK, focusing on offtaking, trading, and transporting green gas, as well as investing in infrastructure.

Key aspects of their involvement include:

Partnerships and Offtake Agreements: Centrica Energy Trading has signed a 15-year agreement with Yorkshire Water and SGN Commercial Services to offtake biomethane from two new gas-to-grid plants in Yorkshire.

Production Capacity: The aforementioned plants, located at Blackburn Meadows and Knostrop, are designed to produce approximately 125GWh of biomethane annually, sufficient to heat over 10,000 homes.

Investment in Bio-LNG/CNG: Centrica acquired a 16% stake in Gasrec, the UK’s largest provider of bio-LNG (liquefied natural gas) and bio-CNG (compressed natural gas) for heavy goods vehicles, supporting the decarbonization of road transport.

Green Gas Trading: Through partnerships like the investment in Barrow Green Gas (BGG), a leading UK green gas supplier, Centrica has established itself as a major player in shipping green gas in the GB network.

Industrial Solutions: Centrica Business Solutions offers “Biomethane CHP” (Combined Heat and Power) to large organizations, enabling them to use green gas certificates to reduce their carbon footprint.

Centrica is aiming to expand its biomethane activities to support its net-zero goals, with a particular focus on using sewage treatment and other waste products for energy.

This seems to fit the pattern of the Irish deal.

Could Centrica be looking for lessons in Ireland, that can be applied to the UK market?

Do British Gas Research Have A Reputation For Innovation?

As British Gas Research developed the heata, which is an idea I like, I felt that it could be enlightening to ask this question of Google AI.

I received this answer.

Yes, British Gas (and its parent company Centrica) has a strong, long-standing reputation for innovation, particularly in the areas of home energy technology, customer services, and net-zero solutions. Their research and development (R&D) efforts are focused on energy efficiency, smart technology, and decarbonization.

Key areas where British Gas demonstrates a reputation for innovation include:

Smart Home Tech (Hive): British Gas pioneered the mass adoption of smart thermostats in the UK with the launch and development of Hive, a key part of their digital strategy for home energy management.

Low Carbon & Renewables: The company is a leading installer of heat pumps and is actively involved in hydrogen innovation for heating solutions.

Digital Customer Experience: They have utilized AI for, among other things, automating complaints root cause analysis and have developed advanced digital tools to allow customers to manage energy usage via apps.

Energy Transition Research: Through Centrica, they invest significant amounts annually in renewable generation and flexible energy solutions to meet net-zero targets.

Data Analytics: British Gas has partnered with research firms to use technologies like eye-tracking to improve the effectiveness of their digital ads and customer engagement.

Strategic Partnerships: They collaborate with industry leaders like Samsung and Barclays to provide energy efficiency incentives and optimize home appliance use.

While they are a major player in new technologies, it is important to note that the broader gas industry is currently focusing on “digital by default” and “flexible and seamless connections” for green gases, as part of their 2026-2028 strategy.

British Gas Research could give the sort of support, that those in the front line need.

Centrica Energy And Whitecap Enter Long-Term Natural Gas Supply Agreement

The title of this post, is the same as that of this news item from Centrica.

This is the sub-heading.

Centrica Energy is pleased to announce signing of a long-term natural gas purchase agreement with Whitecap Resources Inc., a leading Canadian producer dedicated to the responsible development of oil and gas resources across the Western Canadian Sedimentary Basin.

These first three paragraphs add more detail to the story.

Starting in April 2028, Whitecap will deliver 50,000 MMBtu of natural gas per day to Centrica Energy for a period of ten years – equivalent to roughly five LNG cargoes each year. The supply will be priced against the Title Transfer Facility (TTF), the benchmark for European gas markets.

This agreement advances Centrica’s strategy of managing market price exposure across its LNG portfolio by linking feed gas costs to European price signals. For Whitecap, the agreement provides access to international LNG-linked pricing, supporting the company’s natural gas price diversification strategy.

“Entering into this innovative agreement with Whitecap underlines our focus on building a balanced LNG portfolio through strategic partnerships across the globe allowing us to deliver reliable energy solutions to global markets” said Chris O’Shea, Group Chief Executive at Centrica.

I have some thoughts.

This Is The Seventh Deal Of This Type By Centrica In A Few Months

Note.

  1. All are marked with a tag of Natural Gas Trading.
  2. None of the deals appear to be in the Middle East.
  3. All appear to be fairly long term deals, with three stretching until 2037.

Hopefully, with luck we’ll have enough gas for the next few years.

Grain LNG Terminal Is Very Flexible

Consider.

  • It is Europe’s largest LNG Terminal
  • It can import, export and store gas.
  • It has plenty of space for expansion, which could include new technologies.
  • Centrica have said bunkering facilities will be added, which will be able to handle the latest low-carbon fuels.

I can certainly see, why Centrica acquired the terminal.

Is Sumitomo Heavy Industries Highview Power Energy Storage System On Line At Hiroshima?

From some work I did at ICI in the 1970s on a PACE231R analog computer, I believe that Highview Power may have an extremely promising way of storing energy.

The Highview Power web site talks of Sumitomo Heavy Industries, who are building one of Highview’s batteries at Hiroshima in Japan.

So I asked Google AI the question in the title of this post and received this comprehensive answer.

Yes, the Sumitomo Heavy Industries (SHI) Highview Power liquid air energy storage (LAES) commercial demonstration plant in Hatsukaichi, Hiroshima, is operational, having commenced operations on December 1, 2025.

Key details about the plant:
Location: Within the Hiroshima Gas Hatsukaichi LNG Terminal.
Capacity: 5 MW output with 4-hour storage (4 MW charging).
Technology: Uses Highview Power’s CRYOBattery™ technology, specifically utilizing waste cold from the adjacent LNG terminal to improve efficiency.
Role: The facility is designed to support grid stability and enhance renewable energy integration.
A completion ceremony for the project was held on December 9, 2025. This news item from Sumitomo Heavy Industries gives more details.
This paragraph describes Liquid Air Energy Storage or (LAES).
In LAES, surplus power such as off-peak power and renewable energy is utilized to compress and cool air, liquefying it for storage in tanks. When electricity is needed, the liquefied air is pressurized, vaporized, and heated to drive a turbine generator and supply electricity. It is well-suited for long duration energy storage. It not only helps balance electricity supply and demand but also provides a constant, stable supply of inertia and reactive power, thereby contributing to grid stabilization. In combination with unstable renewable energy generation sources like solar power, it can replace thermal power plants.
Note.
  1. It looks like the battery has a capacity of 5 MW/20 MWh.
  2. As it talks about using waste cold, this looks to be a very professionally-designed specialist application.
  3. But surely, that would be expected from a company like Sumitomo Heavy Industries.
Some of the systems, I mathematical-modelled for ICI could certainly have benefited from Highview’s technology.
How Many LNG Terminals Are There In The World?
I asked Google AI the question in the title of this section and received this answer.
There are hundreds of LNG terminals globally, with significant growth driven by over 300 projects (roughly 177 import/regasification and 124 export/liquefaction) expected between 2025 and 2030. In 2023, there were 22 countries with active liquefaction (export) capacity, while Europe alone operates roughly 28 large-scale terminals, supplemented by a rapidly expanding fleet of FSRUs.
Export Capacity: In 2023, global liquefaction capacity was 472 million tonnes per annum (mtpa), with top exporters being Australia, the U.S., and Qatar.
Expansion: By 2027, 52 new liquefaction terminals are expected to commence operations.
Import Growth: European regasification capacity is expanding, with major terminals in Spain, France, Italy, and new additions in Germany and other nations.
U.S. Infrastructure: The U.S. alone has more than 170 LNG facilities performing various services.
There are a lot of LNG Terminals.
  • They are listed in this Wikipedia entry.
  • There are around thirty in Japan alone.
  • Will Centrica add a 5 MW /20 MWh Highview Power battery to their Grain LNG Terminal?
  • Each facility installed is claimed to be designed to support grid stability and enhance renewable energy integration, so the last part must cut carbon emissions.
It would appear, that Sumitomo could keep busy for many years improving the efficiency of LNG Terminals.
Are There Any Other Chemical Engineering Processes That Give Out Lots Of Waste Cold?
I asked Google AI the question in the title of this section and received this answer.
Yes, several major chemical engineering and industrial processes generate significant amounts of “waste cold” (low-grade thermal energy or cryogenic energy) that is often discarded. While the chemical industry conventionally focuses on recovering waste heat, recovering waste cold is becoming increasingly popular for improving energy efficiency, particularly in cryogenic processes.
Here are the primary chemical engineering processes that produce large amounts of waste cold:
  1. Liquefied Natural Gas (LNG) Regasification
  2. Cryogenic Air Separation Units (ASUs)
  3. Dry Ice and CO2 Liquefaction
  4. Liquid Nitrogen Vaporization
  5. Emerging: Cryogenic Carbon Capture
It seems to me that this could be a technology worth exploiting, which Sumitomo are already doing in the case of Liquefied Natural Gas (LNG) Regasification.

  1. Creation of this page was not difficult, but you have to get the tricks right.
  2. I used Google Chrome and Google AI.
  3. My blog is hosted in WordPress.
  4. All pages on this blog, where I have had help in their creation from Google AI are tagged as such.

Centrica Energy And Seneca Resources Company Sign First-of-Its-Kind Long-Term MiQ Methane Emissions Certificates Agreement

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

This is the sub-heading.

Centrica Energy and Seneca Resources Company are proud to announce a groundbreaking agreement, marking the first long-term deal of its kind to support independently verified methane emissions from an MiQ-certified US natural gas producer, helping to underpin reductions over time. This ten-year agreement underscores the commitment of Centrica and Seneca to support global efforts to reduce methane emissions.

This first paragraph added more detail.

Centrica Energy sources and delivers gas and LNG globally, including LNG shipped from the US to international markets. Under the terms of the agreement, Centrica will procure 250,000 MMBtu per day of MiQ-certified gas certificates over the next ten years, a strategic move that positions Centrica at the forefront of methane reduction initiatives, aligns with emerging regulatory requirements, and reinforces leadership in sustainable energy practices.

MiQ is new to me, so here is what the press release says about MiQ.

MiQ is a global leader in methane emissions certification and data. Our mission is to accelerate the transition to lower emissions gas by providing a credible and transparent certification system that drives regulatory compliance, incentivizes continuous improvement, and ensures methane accountability in the oil and gas sector throughout the entire supply chain.

It appears to me that MiQ-certified low-emissions gas is almost like an equivalent of FairTrade coffee.

If the UK buys its gas as MiQ-certified low-emissions gas, it could claim, that it has cut its gas emissions.

Google AI On Low-Emission Natural Gas

I asked its view and received this answer.

Low-emission natural gas refers to methane-based energy with significantly reduced greenhouse gas, methane leakage, and particulate emissions, often achieved through enhanced extraction, certification, or blending with cleaner gases. It offers up to 40% less (CO2) than coal and 20-30% less than oil, serving as a critical transition fuel to support renewable energy. 

low-emission natural gas would seem to be a sensible way to go.

Centrica Energy And Exodus Sign Landmark LNG Agreement

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

This is the sub-heading.

Centrica Energy has announced the signing of a long-term Sale and Purchase Agreement (SPA) to supply liquefied natural gas (LNG) to Exodus for Honduras, marking a new milestone in the country’s energy development.

These two paragraphs add more details.

Under the terms of the agreement, Centrica will deliver approximately six LNG cargoes per year to Exodus through a ship-to-ship operation into the Floating Storage Unit (FSU) Bilbao Knutsen, located in Puerto Cortes. The 15-year contract is expected to commence in 2026.

“This agreement reflects Centrica Energy’s commitment to expanding global LNG access through strategic partnerships,” said Arturo Gallego, Global Head of LNG at Centrica Energy. “By leveraging our global reach and operational expertise, we’re proud to support Exodus and Honduras in its journey toward a more sustainable and resilient energy future.”

It looks a good deal for Centrica, that has been snatched from under the American’s noses.

I also asked Google AI, if Honduras produced any natural gas and received this reply.

No, Honduras does not produce natural gas, but it is importing it through a new liquefied natural gas (LNG) agreement that begins in 2026. The country relies on imports to meet its energy needs, and this new deal aims to diversify its energy mix and provide cleaner energy for power generation.

That’s clear and it’s interesting that Honduras are looking to provide cleaner energy.

These two paragraphs from Centrica’s press release add details on power generation in Honduras.

The LNG will be transported to the Brassavola Combined Cycle Power Plant, an operating 150 MW thermal facility with its combined cycle under construction and set to reach 240 MW of power capacity, marking the first-ever import of natural gas for power generation in Honduras. This initiative represents a significant step toward diversifying the nation’s energy mix and reducing its reliance on less environmentally friendly fossil fuels.

Once operational, the FSU will serve as the backbone of LNG storage at a new terminal currently under construction on Honduras’ Caribbean coast. The project is designed to enhance energy security, improve generation efficiency, and support industrial growth.

This article on Riviera is entitled Honduras Turns To LNG To Meet Energy Needs and provides these points.

  • Honduras is grappling with a 250 MW power shortage.
  • Genesis Energías is spearheading efforts to introduce a reliable and cost-effective energy source by importing liquefied natural gas (LNG).
  • Hyundai, who are one of Centrica’s partners in HiiROC, are converting the Bilbao Knutsen for its new role as a Floating Storage Unit (FSU).

It would certainly help Honduras’s economy, if they had more power generation.

I asked Google AI, if Honduras was developing offshore wind power and received this reply.

While Honduras has been actively developing onshore wind power for over a decade, there is currently no information to suggest it is developing offshore wind power projects. The country’s wind energy development has focused exclusively on land-based projects, with a number of operational farms and more in the pipeline.

I also asked Google AI if Honduras was developing solar power and received this reply.

Yes, Honduras is actively and significantly developing its solar power capacity as a cornerstone of its national energy strategy. The country has been a regional leader in solar energy penetration and continues to invest heavily in new projects to reduce its dependence on fossil fuels.

But, whether its offshore wind, onshore wind or solar power, these renewals will need backup and the 240 MW Brassavola Combined Cycle Power Plant, will be a good start.

I have some further thoughts.

Does HiiROC Have A Part To Play?

If would be good, if the 240 MW Brassavola Combined Cycle Power Plant could be zero-carbon, so that Honduras could be more zero-carbon.

Consider.

  • Centrica own part of HiiROC, who can generate turquoise hydrogen efficiently from natural gas.
  • Honduras will from 2026, have plenty of natural gas.
  • In Hydrogen Milestone: UK’s First Hydrogen-to-Power Trial At Brigg Energy Park, I talked about how Centrica powered Brigg power station with a hydrogen blend.
  • If the Brassavola Combined Cycle Power Plant was reasonably-modern like Brigg, I suspect it could be run on hydrogen or a hydrogen-blend.
  • A reliable supply of hydrogen in Honduras would have its uses.

I wouldn’t be surprised to see a HiiROC plant in Honduras to help decarbonise the country.

HiiROC Creates A Lot Of Carbon Black

When a HiiROC system produces turquoise hydrogen, it produces carbon black as a by-product.

I asked Google AI, if Honduras has a use for carbon black, and received this reply.

Honduras likely has a use for carbon black because the material is a vital component in the production of many common industrial and consumer goods that are used globally. The primary applications are universal across most countries, including those in Central America.

But carbon black can also be used to improve poor agricultural land.

So I asked, Google AI, if Honduras has a lot of land to improve and received this reply.

Yes, Honduras has significant land to improve, but this is complicated by issues like deforestation, land degradation, and a lack of clear land rights for many communities. There is a need to balance economic activities like coffee plantations with conservation, improve sustainable agriculture practices, and address illegal land occupation.

It seems to me, that a sensible hollistic approach could use some of the carbon black.

I also believe, that there are many universities, who could advise Honduras on land restoration.

Does Highview Power Have A Part To Play?

Consider.

  • Centrica are one of the backers of Highview Power, who are building their first two environmentally-friendly liquid air batteries in the UK.
  • Their flagship battery is a 300 MW/3.2 GWh monster that can incorporate a stability island, that controls the grid.
  • Highview Power’s batteries are zero-carbon, with a 40-50 year life.

As a Control Engineer, I believe that one of these batteries would be superb backup for the Brassavola Combined Cycle Power Plant and all those renewables.

Where Will Centrica Get Their LNG For Honduras?

I have already reported on two deals, where Centrica is purchasing LNG.

I can expect more deals like this around the world.

Also, as the Grain LNG Terminal has the ability to export LNG could we be seeing UK natural gas being exported by Centrica to Honduras and the other countries hinted at in the PTT purchase?

Are Centrica Proposing A Comprehensive Solution To A Nation’s Power Problem?

It certainly looks like they are.

And Honduras would be getting a zero-carbon energy system.

This could be repeated all around the world.

 

Conclusion

This certainly looks like a good deal for Centrica, that can be repeated in other places.

Unlocking Efficiency With Cryogenic Cooling Of GaN Traction Inverters

The title of this post, is the same as this insight on the Ricardo web site.

This is the introduction.

As the mobility sector accelerates toward zero-carbon propulsion, hydrogen fuel cell systems (HFCS) are emerging as a cornerstone technology for aviation, marine, and long-haul road transport. Among the most promising innovations in this space is the use of liquid hydrogen (LH₂) not only as a fuel source but also as a cryogenic coolant for electric powertrains. This dual-purpose approach offers transformative potential in system efficiency, packaging, and weight reduction—especially when paired with Gallium Nitride (GaN) semiconductors.

It is a very simple concept, but it appears to give worthwhile efficiency gains.

This was the article’s conclusion.

Ricardo’s cryogenic GaN inverter concept represents a bold leap toward ultra-efficient, lightweight, and integrated hydrogen propulsion systems. While challenges remain in materials, packaging, and reliability, the experimental results are compelling. With efficiencies nearing 99.8% and mass reductions over 50%, cryogenic cooling could redefine the future of electric mobility.

As the hydrogen economy matures, innovations like this will be pivotal in delivering clean, scalable, and high-performance solutions across all mobility sectors.

I very much suggest, that you take the time to read the whole insight.

Using The Concept In a Liquid Hydrogen Carrier

This Wikipedia entry describes the design and operation of an ocean-going liquid hydrogen carrier.

This is a paragraph.

Similar to an LNG carrier the boil off gas can be used for propulsion of the ship.

Ricardo’s concept would appear to be advantageous in the design of liquid hydrogen carriers and I would expect, it could also be applied to the design of LNG carriers.

I would not be surprised to see liquid hydrogen and LNG carriers were the first application of Ricardo’s concept.

This Wikipedia entry describes the Suiso Frontier, which is the world’s only liquid hydrogen carrier.

I believe that Ricardo’s concept could lead to the construction of a more of these ships. Will they mean that liquid hydrogen carriers will deliver hydrogen from sunny climes to places like Europe, Japan, Korea and Canada.

The concept would also enable efficient small liquid hydrogen carriers, that could deliver hydrogen on routes like the North of Scotland to Germany.

Using The Concept In A Railway Locomotive

I could see freight locomotives being designed as a large liquid hydrogen tank with appropriately-sized fuel cells and added electrical gubbins.

  • They would be self-powered and would not require any electrification.
  • They would be much quieter than current diesels.
  • They could pull the heaviest freight trains, between Europe and Asia.
  • They could even pull passenger trains, if an electrical hotel supply were to be arranged.
  • They could be designed with very long ranges.

But above all they would be zero-carbon.

Note that I’ve written about long freight routes before.

I believe that a long-distance liquid-hydrogen locomotive, that was based on the Ricardo concept, would be ideal for some of these routes.

A Specialised Hydrogen Delivery Train

In April 2022, I wrote The TruckTrain, where this is a simple description of the concept.

The Basic Design Concept

The leaflet on their web site describes the concept.

This visualisation at the bottom of the leaflet shows four TruckTrains forming a train carrying twelve intermodal containers, each of which I suspect are 20 feet long.

I believe that the TruckTrain concept could be converted into a hydrogen delivery train.

  • It would be an appropriate length.
  • It would be powered by the on-board hydrogen.
  • The hydrogen would be stored as liquid hydrogen.

It would be able to go most places on the UK rail network.

Conclusion

Ricardo’s concept could revolutionise the use of hydrogen.

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.

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 Enters Into Long Term Natural Gas Sale & Purchase Agreement

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

This is the sub-heading,

Centrica plc today confirmed that its trading arm, Centrica Energy, has entered into a natural gas sale and purchase agreement with US-based Devon Energy Corporation.

This first paragraph adds a few more details.

Under the agreement, Devon Energy will supply 50,000 (MMBtu) per day of natural gas over a 10‑year term starting in 2028. This is equivalent to five LNG cargoes per year. The volumes will be indexed to European gas hub price (TTF). This sale and purchase agreement supports Centrica’s objective of managing market price risk in its LNG portfolio by aligning feed gas pricing with European gas prices whilst providing Devon Energy with international price exposure.

At a first look, it looks a lot of gas.

In Investment In Grain LNG, I talk about Centrica’s purchase of the Grain LNG Terminal from National Grid. But the Grain LNG Terminal comes with several things that Centrica might need for gas from Devon.

  • A large amount of gas storage.
  • The ability to convert liquid natural gas (LNG) into gas suitable for consumers.
  • Space to build more storage if required.
  • The ability to store LNG for other companies.
  • Two jetties for delivering the LNG to the Grain LNG Terminal.
  • The ability to load tankers with LNG, so that it can be sold on to third parties like say the Germans or the Poles.

Centrica also say this about their use of the Grain LNG Terminal in this press release, that describes the purchase of the terminal.

Aligned with Centrica’s strategy of investing in regulated and contracted assets supporting the energy transition, delivering predictable long-term, inflation-linked cash flows, with 100% of capacity contracted until 2029, >70% until 2038 and >50% until 2045.

Centrica have obviously modelled their gas supply and delivery and I believe they have come up with a simple strategy, that will work.

How Will Centrica Use The Gas From The Grain LNG Terminal?

The Wikipedia entry for the Grain LNG Terminal says this about the terminal delivering gas into the gas grid.

The terminal can handle up to 15 million tonnes per annum of LNG, has a storage capacity for one million cubic metres of LNG, and is able to regasify up to 645 GWh per day (58 million cubic metres per day) for delivery into the high pressure gas National Transmission System (NTS).

Note.

  1. This will be one of the major uses of the gas.
  2. I wouldn’t be surprised if these capacities will be increased significantly, so that more gas can be stored and processed.

In Investment in Grain LNG, I outlined how I believe that hydrogen and ammonia will be produced for the bunkering of ships on one of busiest sea lanes in Europe, if not the world.

Some LNG will be used to create these zero-carbon fuels.

Some modern ships, also run on natural gas, so I asked Google AI about their operation and received this answer.

Ships can run on natural gas, specifically liquefied natural gas (LNG), by using it as a fuel source in specially designed engines. LNG is natural gas that has been cooled to a liquid state at -162°C, making it easier to store and transport. This liquid form is then used to power the ship’s engines, either directly or by burning the boil-off gas (BOG) that naturally occurs when LNG warms up.

This means that some LNG could be used to directly fuel these ships.

What Is The Gas Capacity Of The Grain LNG Terminal?

I asked Google AI this question and received this answer.

The Grain LNG Terminal, the largest LNG import terminal in Europe, has a storage capacity of 1,000,000 cubic meters (m³) and an annual throughput capacity of 15 million tonnes of LNG. This is equivalent to about 20% of the UK’s total gas demand. The terminal also has the capacity to deliver 25% of the UK’s daily gas demand.

As the space is there, I wouldn’t be surprised to see Centrica increase the capacity of the terminal, as in cold weather, emergency gas for Germany can be delivered quicker from Kent than the United States.

Could The Grain LNG Terminal Accept Gas Deliveries From The United States?

I’m certain that it already does.

Could The Grain LNG Terminal Accept Gas Deliveries From The UK?

If we start extracting gas again from under the seas around the UK, could the Grain LNG Terminal be used to store it?

Yes, but it would have to be liquified first.

It would be more energy efficient to process the extracted gas, so it could be used directly and gasify enough gas at Grain LNG Terminal from storage to make up any shortfall.

Conclusion

Centrica have done some very deep joined up thinking, by doing a long term gas deal and the Grain LNG Terminal purchase so that they have the gas to supply and somewhere to keep it, until it is needed.
