The Anonymous Widower

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.

Green Hydrogen – Meranti Green Steel Launches Green Iron Project In Oman

The title of this post is the same as that of this article on Hydrogen Central.

The title shows how if you have plenty of energy, you can produce green steel.

Surely, if the Omanis can do it, we can attract a company to make green steel in the UK, as we have lots of renewable energy around our shores.

All the current steelmakers do is blackmail the UK Government into paying them subsidies.

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.

Investment in Grain LNG

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

This sub-heading outlines the deal.

Centrica plc (the “Company”, “Centrica”) is pleased to announce the acquisition of the Isle of Grain liquified natural gas terminal (“Grain LNG”) in partnership1 with Energy Capital Partners LLP (“ECP”) from National Grid group (“National Grid”) for an enterprise value of £1.5 billion. After taking into account approximately £1.1 billion of new non-recourse project finance debt, Centrica’s 50% share of the equity investment is approximately £200 million.

The press release lists these key points.

  • Grain LNG delivers vital energy security for the UK, providing critical LNG import/export, regasification and rapid response gas storage capacity to balance the energy system.
  • 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.
  • Opportunities for efficiencies to create additional near-term value, and future development options including a combined heat and power plant, bunkering, hydrogen and ammonia.
  • Highly efficient funding structure, with Centrica’s equity investment of approximately £200 million alongside non-recourse project financing.
  • Strong life of asset returns aligned with Centrica’s financial framework, with an expected unlevered IRR2 of around 9% and an equity IRR2 of around 14%+
    Underpins delivery of £1.6 billion end-2028 EBITDA target3 – Centrica’s share of EBITDA expected to be approximately £100 million per annum and cash distributions expected to be around £20 million on average per annum for 2026-2028, representing an attractive yield on Centrica’s equity investment
  • Partnership with ECP (part of Bridgepoint Group plc), one of the largest private owners of natural gas generation and infrastructure assets in the U.S. with direct experience in supporting grid reliability.

This Google Map shows the various energy assets on the Isle of Grain.

 

Note.

  1. It appears that works for the 1, 400 MW NeuConnect interconnector to Wilhelmshaven in Germany, are taking place in the North-East corner of the map.
  2. Grain CHP powerstation is a 1,275MW CCGT power station, which is owned by German company; Uniper, that is in the South-East corner of the map, which can also supply up to 340MW of heat energy recovered from the steam condensation to run the vapourisers in the nearby liquefied natural gas terminal.
  3. The Grain LNG terminal is at the Western side of the map.
  4. In the Thames Estuary to the East of the Isle of Grain, I estimate that there are about 1,500 MW of wind turbines.

I find it interesting that two of the assets are German owned.

I have some thoughts.

It Is A Large Site With Space For Expansion

This Google Map shows the whole of the Isle of Grain.

Note.

  1. The Grain LNG terminal is around the label Wallend.
  2. The River Medway runs East-West at the bottom of the map.
  3. Gas tankers deliver and take on gas at jetties on the North Bank of the Medway.

There could be space to expand the terminal, if the RSPB would allow it.

As an example, I asked Google AI, if peregrine falcons nest on chemical plants and got this reply.

Yes, peregrine falcons do nest on chemical plants. They have adapted to using various urban and industrial structures, including chemical plants, for nesting. This is particularly true in areas where natural cliff habitats are scarce.

Peregrine falcons are known for their adaptability, and their population has seen a resurgence in recent decades, partly due to their ability to utilize man-made structures. These structures often mimic their natural cliffside nesting

Cliffs do seem scarce on the Isle of Grain. I also asked Google AI, if peregrine falcons ate small rodents, as several chemical and other plants, where I’ve worked, had a rodent problem. One plant had a cat problem, as there had been so many rats. This was the reply.

Yes, peregrine falcons do eat small rodents, though they primarily consume birds. While their diet mainly consists of other birds like pigeons, doves, and waterfowl, they will also hunt and eat small mammals, including rodents such as mice, rats, and voles. They are opportunistic hunters and will take advantage of readily available prey, including insects, amphibians, and even fish.

I’m sure if Centrica wanted to expand, they’d employ the best experts.

Who Are ECP?

One of the key points of the press release is that this deal is a partnership with ECP (part of Bridgepoint Group plc), one of the largest private owners of natural gas generation and infrastructure assets in the U.S. with direct experience in supporting grid reliability.

The Wikipedia entry for ECP or Energy Capital Partners has this first section.

Energy Capital Partners Management, LP (ECP) is an American investment firm headquartered in Summit, New Jersey. It focuses on investments in the energy sector. The firm has additional offices in New York City, Houston, San Diego, Fort Lauderdale and Seoul.

In August 2024, ECP merged with Bridgepoint Group to form a private assets investment platform.

The Wikipedia entry for the Bridgepoint Group has this first paragraph.

Bridgepoint Group plc is a British private investment company listed on the London Stock Exchange and is a constituent of the FTSE 250 Index.

The company had started as part of NatWest.

Are The Germans Going To Take Away Some Of Our Electricity?

Consider.

  • Germany has a big need to replace Russian gas and indigenous coal, and to decarbonise.
  • Neuconnect is a 1.4 GW interconnector between the Isle of Grain and Wilhelmshaven in Germany. It is scheduled to be completed in 2028.
  • The Grain CHP powerstation is a 1,275MW CCGT power station, which is owned by German company; Uniper, could almost keep NeuConnect working at full power on its own.
  • I said earlier, in the Thames Estuary to the East of the Isle of Grain, I estimate that there are about 1,500 MW of wind turbines. One of which is part German-owned.

The Germans are also building a large electrolyser at Wilhelshaven, which is described by Google AI like this.

The Wilhelmshaven Green Energy Hub will initially feature a 500MW electrolyzer, with plans to potentially expand to 1GW, according to Energy Monitor. The hub, a joint project between Tree Energy Solutions (TES) and EWE, aims to produce green hydrogen using renewable energy sources like offshore wind. The 500MW electrolyzer is scheduled to be operational by 2028.

I wouldn’t be surprised to see that the Wilhelmshaven electrolyser were to be powered by British-generated electricity flowing down NeuConnect.

Centrica Says Their Future Development Options Include A Combined Heat And Power Plant

This objective was set in one of the key points.

This is the first paragraph of the Wikipedia entry for the Grain LNG Terminal.

Grain LNG Terminal is a Liquefied Natural Gas (LNG) terminal on the Isle of Grain, 37 miles (60 km) east of London. It has facilities for the offloading and reloading of LNG from ships at two jetties on the River Medway; for storing and blending LNG; for truck loading; and regasifying and blending natural gas to meet UK specifications. 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). The facility is owned and operated by National Grid Grain LNG Ltd, a wholly owned subsidiary of National Grid.

Note.

  1. This paragraph was written before the Centrica takeover.
  2. The terminal also converts liquid natural gas into gas to be distributed around the UK.

The heat needed to convert the liquid natural gas to gas is provided by the Grain CHP power station.

  • Currently 340 MW of heat is provided.
  • If the Grain LNG terminal is expanded, it will probably need more heat.

I can see Centrica building a combined heat and power (CHP) power station, that can be expanded to meet the current and future needs of gasification at the Grain LNG terminal.

I wouldn’t be surprised to see the CHP power station fitted with carbon capture, as Kent is surely one county, where carbon dioxide can be used in food production, so we can generate our carbon dioxide and eat it.

 

 Centrica Says Their Future Development Options Include Hydrogen

This objective was set in one of the key points.

Consider.

  • Centrica are an investor in HiiROC, who have a unique method of generating affordable zero-carbon hydrogen called thermal plasma electrolysis, which uses a fifth of the electricity, that traditional electrolysis does.
  • HiiROC can use natural gas as a feedstock. Centrica won’t be short of that at Grain.
  • There is space to build a large HiiROC system at the Isle of Grain site.
  • The hydrogen could be taken away by tanker ships.

Like the electricity , which will use the 450 mile NeuConnect interconnector, the hydrogen could even be exported to Wilhelmshaven in Germany by pipeline.

Wilhelmshaven is being setup to be a major German hub to both generate, import and distribute hydrogen.

 

I asked Google AI, how much hydrogen a GWh would produce and received this answer.

A GWh of electricity can produce approximately 20-22 tonnes of hydrogen through electrolysis, depending on the efficiency of the electrolyzer. Modern commercial electrolyzers operate at an efficiency of roughly 70-80%, meaning they require about 50-55 kWh of electricity to produce 1 kg of hydrogen. A GWh (1 gigawatt-hour) is equal to 1,000,000 kWh, and 1 tonne of hydrogen contains roughly 33.33 MWh of energy. 

As it is claimed on the web that HiiROC is five times more efficient than traditional electrolysis, it could need around 10-11 kWh to produce one kg. of hydrogen.

1 GWh would produce between 90-100 tonnes of hydrogen.

 Centrica Says Their Future Development Options Include Ammonia

This objective was set in one of the key points.

I asked Google AI if ammonia can be produced from hydrogen and received this answer.

Yes, ammonia (NH3) can be produced from hydrogen (H2) through a process called the Haber-Bosch process. This process involves combining hydrogen with nitrogen (N2) from the air, under high temperature and pressure, in the presence of a catalyst.

Ammonia has a large number of uses, including making fertiliser and the powering of large ships.

I asked Google AI, if there are small Haber-Bosch processes to make ammonia from hydrogen and nitrogen and received this answer.

Yes, there are efforts to develop smaller-scale Haber-Bosch processes for ammonia production. While the traditional Haber-Bosch process is typically associated with large industrial plants, research and development are exploring ways to adapt it for smaller, distributed production, particularly for localized fertilizer or fuel applications.

I wondered if Centrica are involved in the efforts to develop smaller-scale Haber-Bosch processes for ammonia production.

Google AI gave me this quick answer.

Centrica is involved in research related to the Haber-Bosch process, particularly in the context of transitioning to a low-carbon energy future. They are exploring how to adapt the Haber-Bosch process, which is crucial for fertilizer production but also a significant source of CO2 emissions, to utilize renewable energy sources. This includes investigating the use of green hydrogen produced from water electrolysis and renewable electricity. Centrica is also involved in research related to using ammonia as a fuel, including potentially for power generation

That looks to be a very positive answer. Especially, as local low-carbon fertiliser production could be a very powerful concept.

Centrica Says Their Future Development Options Include Bunkering

This objective was set in one of the key points.

Bunkering is the process of refuelling ships.

I didn’t know much about bunkering, when I started to read Centrica’s press release, but the Wikipedia entry, was a good way to get some information.

This section in the Wikipedia entry is entitled Two Types Of Bunkering, where this is said.

The two most common types of bunkering procedure at sea are “ship to ship bunkering” (STSB), in which one ship acts as a terminal, while the other moors. The second type is “stern line bunkering” (SLB), which is the easiest method of transferring oil but can be risky during bad weather.

Over the years, I have found, that two zero-carbon fuels are under development, for powering ships; hydrogen and ammonia. Others are developing ships powered by naturalo gas.

I asked Google AI if hydrogen can power ships and received this answer.

Yes, hydrogen can power ships. It can be used as a fuel for fuel cells, which generate electricity to power the ship’s propulsion and other systems, or it can be burned in modified combustion engines. Hydrogen offers a zero-emission solution for shipping, with water vapor being the only byproduct when used in fuel cells.

Google AI also told me this.

The world’s first hydrogen-powered cruise ship, the “Viking Libra”, is currently under construction and is scheduled for delivery in late 2026. This innovative vessel, a collaboration between Viking Cruises and Italian shipbuilder Fincantieri, will utilize hydrogen for both propulsion and electricity generation, aiming for zero-emission operation.

I also asked Google AI if ammonia can power ships and received this answer.

Yes, ammonia can be used to power ships and is considered a promising alternative fuel for the maritime industry. Several companies and organizations are actively developing ammonia-powered ship designs and technologies. While challenges remain, particularly around safety and infrastructure, ammonia is seen as a key potential fuel for decarbonizing shipping.

Finally, I asked I asked Google AI if natural gas can power ships and received this answer.

Yes, ships can be powered by natural gas, specifically in the form of liquefied natural gas (LNG). LNG is increasingly used as a marine fuel, offering environmental benefits over traditional fuels like diesel.

It would seem to be a case of you pays your money and makes a choice between one of four technologies; ammonia, hydrogen fuel-cell, hydrogen-ICE and LNG.

I looks to me, that if Centrica provide bunkering services for ships, they have the means to cover most of the market by providing hydrogen and ammonia, in addition to natural gas.

Although, I don’t know much about bunkering, I do feel that the two current methods, that work for oil, could be made to work for these fuels.

This Google Map shows the Thames Estuary.

Note.

  1. The Port of Tilbury is in the South-West corner of the map.
  2. London Gateway is indicated by the red arrow.
  3. The Isle of Grain is in the South-East corner of the map.
  4. Other ports between Tilbury and the Isle of Grain include Barking, Dagenham, Dartford, Erith, Greenwich, Northfleet, Purfleet, Silvertown and Thurrock.

There was never a more true phrase than – “Location, Location and Location”. And the Isle of Grain would appear to be in the right place to send out a bunkering tanker to a passing ship, that was calling at a port in London or just passing through the Strait of Dover.

This Google Map shows the Thames between London Gateway and the Isle of Grain.

Note.

  1. London Gateway is indicated by the red arrow.
  2. The Isle of Grain is in the South-East corner of the map.

It seems to me, that a refuelling philosophy could easily be worked out.

How Large is The Bunkering Market?

I asked Google AI this question and received this answer.

The world bunker fuel market is a multi-billion dollar industry, with the market size valued at USD 150.93 billion in 2023. It is projected to reach USD 242.29 billion by 2032, growing at a CAGR of 5.4% according to SkyQuest Technology. In terms of volume, the global bunker demand was estimated at 233.1 million metric tons in 2023 according to the IMO.

The market is not small!

Demonstration Of Commercial-Size Hydrogen Module

The title of this post, is the same as that of news item on the SunHydrogen web site.

This is the sub-heading.

SunHydrogen has successfully demonstrated live operation of its commercial-size 1.92m² hydrogen module, producing renewable hydrogen using only sunlight and water. This major milestone showcases the scalability and off-grid potential of the company’s renewable hydrogen production technology.

These first three paragraphs add more details.

SunHydrogen, developer of a breakthrough technology to produce renewable hydrogen using sunlight and water, today announced the successful live operation of its 1.92 m² (20.7 sq. ft.) hydrogen module. Conducted in an open prototype housing, the demonstration marks a pivotal milestone in the company’s path toward commercial-scale, renewable hydrogen production.

The 1.92m² hydrogen module, which uses only sunlight and water to produce hydrogen, represents the most advanced version of SunHydrogen’s proprietary hydrogen production technology. Engineered to operate independent of the electrical grid, the system integrates solar collection and hydrogen production into a single unit, offering a modular and scalable solution for distributed renewable hydrogen.

“This successful demonstration of the commercial-size reactor underscores the progress we’ve made in bringing our technology out of the lab and into the real world,” said Tim Young, CEO of SunHydrogen.

There is a video of this demonstration.

On their home page, there is a section called A Breakthrough In Clean Energy, where this is said.

SunHydrogen has developed a breakthrough technology to produce renewable hydrogen using sunlight and any source of water.

By optimizing the science of water electrolysis at the nano-level, our low-cost photoelectrochemical technology uses sunlight to separate hydrogen from water, making the process truly green from start to finish.

I will accept their word that it is truly green, but it is truly unique in that it doesn’t appear to use only sunlight to generate hydrogen.

£125m Hydrogen Supply Deal To Replace Gas Usage

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

This is the sub-heading.

Tissue maker Kimberly-Clark has signed a £125m contract with two hydrogen facilities to reduce the amount natural gas used in its production line

These five paragraphs give more details.

The Andrex and Kleenex producer signed a long-term deal receive hydrogen from the upcoming Carlton Power facility in Barrow-in-Furness, Cumbria, and the HYRO plant in Northfleet, Kent, which are expected to be operational in 2027.

The facilities have already secured funding and planning permission and will be built near existing Kimberly-Clark plants.

The company said that, as a result of the deal, from 2027 it expected to see a 50% reduction to its 2024 consumption of natural gas across its UK production lines.

The new facilities will produce and store hydrogen for the exclusive use of Kimberly-Clark.

It would replace fossil-fuel natural gas used for steam generation in the manufacture of toilet and facial tissues, the company said.

I would expect that converting an industrial steam-generator from natural gas to hydrogen operation could be a reasonably straightforward task.

I have these thoughts.

Will Kimberly-Clark Advertise Their Future Products As Carbon-Free?

I suspect they could, if they looked at where everything they used came from.

Will Carbon-Free Tissue Products Sell Better?

This will be the acid test. And of course the sums must add up.

Will Kimberly-Clark Make Their Tissue Products Plastic Free?

There is an article in The Times today, which is entitled Work Starts To Remove ‘Wet Wipe Island’ From Thames, which says this.

The congealed mass of wet wipes has formed on the Surrey side of the river near Hammersmith Bridge and was described on Sunday night as an “embarrassment to the capital”.

Plastic-free products would go a long way to solve the problem of ‘Wet Wipe Island’

Surely, a double change to carbon- and plastic-free will be better than two single changes.

Will Kimberly-Clark Use Hydrogen-Powered Trucks To Deliver Finished Products?

Availability of hydrogen is often cited for not using hydrogen-powered trucks.

But that won’t apply at Barrow-in-Furness or Northfleet.
