The Anonymous Widower

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!

Flotation, Vargronn Complete NorthConnect Deal

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

This is the sub-heading.

1.4GW Cenos floater backers seal ‘productive partnership’ with interconnector acquisition

These three paragraphs add more details to the deal.

Flotation Energy and Vargronn have closed their acquisition of the NorthConnect interconnector project between Scotland and Norway.

The developers said the deal had followed close collaboration on shared transmission infrastructure and a common grid connection point for the interconnector and the proposed 1.4GW Cenos floating wind farm off east Scotland.

NorthConnect already has consent for an offshore and onshore cable route to a substation near Boddam, Aberdeenshire, that will link to SSEN’s Peterhead substation.

This looks like a clever use of the permissions for the interconnector to connect the Cenos wind farm to the grid.

Offshore Grid For Irish, Celtic and North Seas Closer To Delivery

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

This is the sub-heading.

Joint development can be ‘key step for Europe’s energy future’ and climate neutrality

These paragraphs add detail.

EirGrid and other leading European power transmission system operators (TSOs) have backed moves to develop an offshore electricity grid for the Irish, Celtic and North seas.

The next stage in a collaboration, being undertaken by nine system operators under the Offshore TSO Collaboration (OTC), was announced at the WindEurope annual conference in Copenhagen on Wednesday.

It followed the initial results of a pilot study evaluating how the grid could be established.

The report supports Europe’s goal of establishing a “green power plant” offshore that will play a crucial role in the Continent securing an independent, affordable and climate-neutral energy supply.

If you open the article, there is an excellent map of the various interconnectors, that will be in place by 2040.

Conclusion

This is all good stuff and can only lead to energy security for the participating countries.

Drax To Get £24m In Green Subsidies For Pumped Hydro

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

These three paragraphs give details of the subsidy.

Drax will bank £24 million in green subsidies from energy bill-payers for its pumped hydro assets, ahead of a revival in the energy storage technology in Britain.

The FTSE 250 constituent, which also operates Britain’s largest power station in North Yorkshire, has secured contracts to provide 434 megawatts of capacity from its pumped storage and hydro assets, the largest of which is the Cruachan power station near Oban in Scotland.

The contracts cover energy to be delivered between October 2028 to September 2029, at a price of £60 a kilowatt a year.

This will arouse the anti-Drax lobby, but it should be born in mind, that according to Wikipedia, Cruachan can provide a black start capability to the UK’s electrical grid.

This is Wikipedia’s definition of a black start.

 

A black start is the process of restoring an electric power station, a part of an electric grid or an industrial plant, to operation without relying on the external electric power transmission network to recover from a total or partial shutdown.

After the Great Storm of 1987, we were without power in my part of Suffolk for two weeks and I suspect there were several black starts in the South of England.

I suspect that power from interconnectors could now be used.

Drax is expanding Cruachan from 440 MW to 1 GW, which will be a large investment and surely increase its black start capability.

So in this case the future subsidy could be considered something like an insurance policy to make sure black start capability is available.

UK, Netherlands To Connect Grids via Nederwiek 3 Offshore Wind Farm

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

This is the sub-heading.

Dutch Climate and Green Growth Minister Sophie Hermans has included LionLink, said to be the first direct-current hybrid interconnector, in the country’s latest Offshore Wind Energy Development Framework. LionLink will use the offshore grid connection of Nederwiek 3 offshore wind farm in the Netherlands to connect to both the Dutch and the UK onshore high-voltage grids.

These are points from the article.

  • The interconnector can also be used as an additional high-voltage link to exchange electricity between the countries.
  • With LionLink now added to the offshore wind development framework, TenneT may now make investments in the project, which the Dutch transmission system operator (TSO) is realising in close cooperation with UK partner National Grid Ventures (NGV).
  • Nederwiek 3 is planned to be launched in 2026.

The offshore grid between the UK and Europe is on its way.

Race For Clean Power Surges Ahead As New Electricity Superhighway Greenlit

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

These three paragraphs, explain the infrastructure.

Flagged by the National Energy System Operator (NESO) as an essential element in achieving the Government’s Clean Power 2030 ambition, Eastern Green Link 1 (EGL1As part of its mission to rapidly upgrade the energy system with a minimum cost to customers, Ofgem has identified over £43m of savings which have been cut from the project costs without impacting delivery or quality. Communities that host the infrastructure in Scotland and North-East England are also set to benefit from a £7.9m social value and community benefit fund.) is a high voltage electricity superhighway able to transport 2 gigawatts of homegrown wind generated electricity between Torness, East Lothian and Hawthorn Pit, County Durham. A gigawatt (GW) is equivalent to one billion watts, and one gigawatt hour (GWh) of electricity is enough to power one million homes for one hour. Most of the 196km cable will be under the North Sea, with the remaining 20km of cables underground linking the cable to substations and converter stations in Scotland and England.

The project will reduce Great Britain’s reliance on volatile international gas markets by further harnessing the power of homegrown North Sea wind. NESO’s recent Clean Power 2030 Report has also shown that the project will deliver annual saving of over £870m by reducing the need to compensate British wind generators who are currently asked to turn off production during times of high wind due to lack of grid capacity. This in turn will help drive down consumer bills.

Note.

  1. Eastern Green Link 1 (EGL1) is a high voltage electricity superhighway able to transport 2 gigawatts of homegrown wind generated electricity between Torness, East Lothian and Hawthorn Pit, County Durham.
  2. This is the second down the eastern side of the UK.
  3. In Contracts Signed For Eastern Green Link 2 Cable And Converter Stations, I described how contracts were signed for EGL2 from Peterhead in Scotland to Drax in England .
  4. Most of the 196km cable will be under the North Sea, with the remaining 20km of cables underground linking the cable to substations and converter stations in Scotland and England.

There are another two 2 GW cables to follow in the current plan!

UK To Fund Hydro Energy Storage Projects

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

This is the sub-heading.

New infrastructure aims to help balance the electricity system after the rapid growth in renewables

These three paragraphs infrastructure the article.

Projects that use water to store and release energy are to be given government support, in an attempt to help manage the volatility in supply and demand as more green power enters the grid.

From next year, pumped hydro storage projects will be able to apply for government subsidies, which will be provided via a “cap and floor” mechanism. These would guarantee revenues if prices drop below a certain floor but prevent providers from charging above a ceiling when power prices are high.

Like other government support schemes, any cost will be levied on energy bills, while consumers will be paid back any money generated above the cap. It is yet to be decided precisely how the cap and floor will be set.

I feel it is reasonable to expect the system to be a success, as a similar system is used for interconnectors and this article on Offshore Energy is entitled Over $86 million To Be Split Between UK and Belgium Consumers As 1 GW Subsea Interconnector’s ‘Remarkable’ Revenues Exceed Ofgem’s Cap.

It looks like Ofgem played this right for interconnectors and the Nemo Link is making a substantial payment.

It will be interesting to see what happens when “cap and floor” contracts are assigned.

This move by Ofgem will probably have effects in two areas.

  • SSE, Statera and Statkraft, who are typically developing systems at the high end with a size of about 1.5 GW/25 GWh could find money is easier to come by.
  • At the lower end, companies like Highview Power, who have systems of 50 MW/300 MWh and 200 MW/2.5 GWh under development, will also benefit.

My Control Engineering thoughts are leaning towards the 200 MW/2.5 GWh systems being the popular ones. Especially as they would appear to be close to the right size to support a 1 GW wind farm for two hours.

A Highview Power Two-Hour Liquid Air Battery could fit nearly with a fleet of Two-Hour BESS.

It should be noted that CAF use a little-and-large approach to theit battery-electric trams in the West Midlands.

A large lithium-ion battery is the main storage device.

A supercapacitor handles the high-frequency response and keeps the power steady.

Pairing a Highview Power Two-Hour Liquid Air Battery and a Two-Hour BESS could achieve the same performance and possibly result in some cost savings.

What Are Offshore Hybrid Assets?

The title of this post is the same as that of a story explaining energy from National Grid.

This is the sub-heading.

Offshore Hybrid Assets or OHAs (formerly known as multi-purpose interconnectors) are a new generation of subsea technology that will connect clusters of offshore wind farms to multiple countries.

This is the first paragraph.

OHAs will help to speed up the connection of offshore wind and maximise the use of wind generation. They will also reduce the impact on local communities by reducing the amount of connection points and onshore infrastructure required to connect this clean energy to the shore.

The story goes on to discuss OHAs and how they are being developed.

It is very much a must read.

RWE Goes For An Additional 10 GW Of Offshore Wind In UK Waters In 2030

This press release from RWE is entitled RWE And Masdar Join Forces To Develop 3 Gigawatts Of Offshore Wind Projects Off The UK Coast.

This is the last paragraph.

The UK plays a key role in RWE’s strategy to grow its offshore wind portfolio RWE is a leading partner in the delivery of the UK’s Net Zero ambitions and energy security, as well as in contributing to the UK build-out target for offshore wind of 50 GW by 2030. RWE already operates 10 offshore wind farms across the UK. Following completion of the acquisition of the three Norfolk offshore wind projects from Vattenfall announced at the end of 2023, RWE is developing nine offshore wind projects in the UK, representing a combined potential installed capacity of around 9.8 GW, with RWE’s pro rata share amounting to 7 GW. Furthermore, RWE is constructing the 1.4 GW Sofia offshore wind project in the North Sea off the UK’s east coast. RWE’s unparalleled track record of more than 20 years in offshore wind has resulted in 19 offshore wind farms in operation, with a goal to triple its global offshore wind capacity from 3.3 GW today to 10 GW in 2030.

Note.

  1. Nine offshore wind projects in the UK, representing a combined potential installed capacity of around 9.8 GW
  2. RWE are saying they intend to add 6.7 GW in 2030.

The eight offshore wind farms, that RWE are developing in UK waters would appear to be.

  • Sofia – 1,400 MW
  • Norfolk Boreas – 1380 MW
  • Norfolk Vanguard East – 1380 MW
  • Norfolk Vanguard West – 1380 MW
  • Dogger Bank South – 3000 MW
  • Awel y Môr – 500 MW
  • Five Estuaries – 353 MW
  • North Falls – 504 MW

This is a total of 9897 MW, which ties in well with RWE’s new capacity figure of 9.8 GW.

The Location Of RWE’s Offshore Wind Farms

RWE’s wind farms seem to fit in groups around the UK.

Dogger Bank

This wind farm is on the Dogger Bank.

  • Dogger Bank South – 3000 MW – Planned

This wind farm would appear to be rather isolated in the middle of the North Sea.

RWE could have plans to extend it or even link it to other wind farms in the German area of the Dogger Bank.

Lincolnshire Coast

This wind farm is along the Lincolnshire Coast.

  • Triton Knoll – 857 MW – 2022

As there probably isn’t much heavy industry, where Triton Knoll’s power comes ashore, this wind farm can provide the power needed in the area.

But any excess power in the area can be exported to Denmark through the Viking Link.

Norfolk Coast

These wind farms are along the Norfolk Coast.

  • Norfolk Boreas – 1380 MW – Planned
  • Norfolk Vanguard East – 1380 MW – Planned
  • Norfolk Vanguard West – 1380 MW – Planned

These three wind farms will provide enough energy to provide the power for North-East Norfolk.

North Wales Coast

These wind farms are along the North Wales Coast.

  • Awel y Môr – 500 MW – Planned
  • Gwynt y Môr – 576 MW – 2015
  • Rhyl Flats  – 90 MW – 2009
  • North Hoyle – 60 MW – 2003

These wind farms will provide enough energy for the North Wales Coast.

Any spare electricity can be stored in the 1.8 GW/9.1 GWh Dinorwig pumped storage hydroelectric power station.

Electric Mountain may have opened in 1984, but it is surely a Welsh giant decades ahead of its time.

Suffolk Coast

These wind farms are along the Suffolk Coast.

  • Five Estuaries – 353 MW – Planned
  • Galloper – 353 MW – 2018
  • North Falls – 504 MW – Planned

These wind farms will provide enough energy for the Suffolk Coast, which except for the Haven Ports, probably doesn’t have many large electricity users.

But if the area is short of electricity, there will be Sizewell B nuclear power station to provide it.

Teesside

This wind farm is along the Teesside Coast

  • Sofia – 1,400 MW – Planned

Teesside is a heavy user of electricity.

These six areas total as follows.

  • Dogger Bank – 3,000 MW
  • Lincolnshire Coast – 857 MW
  • Norfolk Coast – 4140 MW
  • North Wales Coast – 1226 MW
  • Suffolk Coast – 1210 MW
  • Teesside – 1,400 MW

Backup for these large clusters of wind farms for when the wind doesn’t blow will be provided as follows.

  • Dogger Bank – Not provided
  • Lincolnshire Coast- Interconnectors to Denmark and Scotland
  • Norfolk Coast – Not provided
  • North Wales Coast – Stored in Dinorwig pumped storage hydroelectric power station
  • Suffolk Coast – Sizewell B and Sizewell C
  • Teesside – Interconnectors to Norway and Scotland and Hartlepool nuclear power stations

Note.

  1. The interconnectors will typically have a 2 GW capacity.
  2. The 1.9 GW/9.1 GWh Dinorwig pumped storage hydroelectric power station must be one of the best wind farm backups in Europe.

There is a very solid level of integrated and connected assets that should provide a reliable power supply for millions of electricity users.

How Will Dogger Bank And The Norfolk Coast Wind Clusters Work Efficiently?

The Dogger Bank and the Norfolk Coast clusters will generate up to 3 and 4.14 GW respectively.

So what purpose is large amounts of electricity in the middle of the North Sea?

The only possible purpose will be to use giant offshore electrolysers to create hydrogen.

The hydrogen will then be transported to point of use by pipeline or tanker.

Feeding H2ercules

I described H2ercules in H2ercules.

H2ercules is an enormous project that will create the German hydrogen network.

The H2ercules web site, shows a very extensive project, as is shown by this map.

Note.

  1. Hydrogen appears to be sourced from Belgium, the Czech Republic, The Netherlands and Norway.
  2. RWE’s Dogger Bank South wind farm will be conveniently by the N of Norway.
  3. RWE’s Norfolk cluster of wind farms will be conveniently by the N of Netherlands.
  4. The Netherlands arrow points to the red circles of two hydrogen import terminals.

For Germany to regain its former industrial success, H2ercules  will be needed to be fed with vast amounts of hydrogen.

And that hydrogen could be in large amounts from the UK sector of the North Sea.

Uniper’s Wilhelmshaven Hydrogen Hub

This page on the Uniper web site is entitled Green Wilhelmshaven: To New Horizons

This Uniper graphic shows a summary of gas and electricity flows in the Wilhelmshaven Hydrogen Hub.

Note.

  1. Ammonia can be imported, distributed by rail or ships, stored or cracked to provide hydrogen.
  2. Wilhelmshaven can handle the largest ships.
  3. Offshore wind energy can generate hydrogen by electrolysis.
  4. Hydrogen can be stored in underground salt caverns.

I suspect hydrogen could also be piped in from an electrolyser in the East of England or shipped in by a hydrogen tanker.

All of this is well-understood technology.

Sunak’s Magic Money Tree

Rishi Sunak promised a large giveaway of tax in his manifesto for the 2024 General Election.

As we are the only nation, who can provide the colossal amounts of hydrogen the Germans will need for H2ercules, I am sure we will be well paid for it.

A few days ago we celebrated D-Day, where along with the Americans and the Canadians, we invaded Europe.

Now eighty years later, our hydrogen is poised to invade Europe again, but this time for everybody’s benefit.

This document on the Policy Mogul web site is entitled Rishi Sunak – Conservative Party Manifesto Speech – Jun 11.

These are three paragraphs from the speech.

We don’t just need military and border security. As Putin’s invasion of Ukraine has shown, we need energy security too. It is only by having reliable, home-grown sources of energy that we can deny dictators the ability to send our bills soaring. So, in our approach to energy policy we will put security and your family finances ahead of unaffordable eco zealotry.

Unlike Labour we don’t believe that we will achieve that energy security via a state-controlled energy company that doesn’t in fact produce any energy. That will only increase costs, and as Penny said on Friday there’s only one thing that GB in Starmer and Miliband’s GB Energy stands for, and that’s giant bills.

Our clear plan is to achieve energy security through new gas-powered stations, trebling our offshore wind capacity and by having new fleets of small modular reactors. These will make the UK a net exporter of electricity, giving us greater energy independence and security from the aggressive actions of dictators . Now let me just reiterate that, with our plan, we will produce enough electricity to both meet our domestic needs and export to our neighbours. Look at that. A clear, Conservative plan not only generating security, but also prosperity for our country.

I believe that could be Rishi’s Magic Money Tree.

Especially, if the energy is exported through electricity interconnectors or hydrogen or ammonia pipelines and tankers.

Will This Be A Party Anyone Can Join?

Other wind farm clusters convenient for the H2ercules hydrogen import terminals on the North-West German coast include.

  • Dogger Bank – SSE, Equinor – 5008 MW
  • East Anglian – Iberdrola – 3786 MW
  • Hornsea – Ørsted – 8056 MW

That totals to around 16.5 GW of wind power.

I can see offshore electrolysers producing hydrogen all around the coasts of the British Isles.

What Happens If Sunak Doesn’t Win The Election?

RWE and others have signed contracts to develop large wind farms around our shores.

They didn’t do that out of the goodness of their hearts, but to make money for themselves and their backers and shareholders.

Conclusion

I believe a virtuous circle will develop.

  • Electricity will be generated in the UK.
  • Some will be converted to hydrogen.
  • Hydrogen and electricity will be exported to the highest bidders.
  • European industry will, be powered by British electricity and hydrogen.
  • Money will be paid to the UK and the energy suppliers for the energy.

The more energy we produce, the more we can export.

In the future more interconnectors, wind farms and electrolysers will be developed.

Everybody will benefit.

As the flows grow, this will certainly become a Magic Money Tree, for whoever wins the election.

Ørsted, Simply Blue, Subsea7 Submit Application For 100 MW Scottish Floating Wind Farm

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

This is the sub-heading.

Ørsted, Simply Blue Group and Subsea7, through their joint venture partnership in Scotland, have submitted an offshore consent application for the proposed 100 MW Salamander floating offshore wind farm, one of the 13 projects selected in Scotland’s Innovation and Targeted Oil and Gas (INTOG) leasing round.

The article starts with a map that shows the location of the Salamander floating offshore wind farm and it shows how the sea is getting very crowded 35 kilometres off Peterhead.

This map shows the various ScotWind leases, around the North of Scotland.

 

The numbers are Scotwind’s lease number in their documents.

These are the Scotwind wind farms to the North-East of Scotland.

  • 1 – BP Alternative Energy Investments – 859 km² – 2.9 GW – Fixed
  • 2 – SSE Renewables – 859 km² – 2.6 GW – Floating
  • 3 – Falck Renewables Wind – 280 km² – 1.2 GW – Floating
  • 4 – Shell – 860 km² – 2.0 GW – Floating
  • 5 – Vattenfall – 200 km² – 0.8 GW – Floating
  • 6 – DEME – 187 km² – 1.0 GW – Fixed
  • 9 – Ocean Winds – 429 km² – 1.0 GW – Fixed
  • 10 – Falck Renewables Wind – 134 km² – 0.5 GW – Floating
  • 11 – Scottish Power Renewables – 684 km² – 3.0 GW – Floating
  • 12 – BayWa r.e. UK  – 330 km² – 1.0 GW – Floating

Note.

  1. Salamander is located to the South of wind farms 10, 11 and 12 and to the North-West of wind farm 5.
  2. These windfarms total up to 16 GW.
  3. 4.9 GW are fixed foundation wind farms.
  4. 11.1 GW are floating wind farms.

These are my thoughts.

The Salamander Project

In the big scheme of things, the 100 MW Salamander wind farm, is rather a tiddler of a wind farm.

On the Salamander wind farm web site, a section gives the Project Goals.

  1. Our innovative pre-commercial stepping-stone concept will use novel floating foundations to (i) maximise Scottish content, (ii) enable the Scottish supply chain to gear up for the future floating offshore wind commercial opportunities in ScotWind and (iii) reduce the financial, environmental and technology risks of floating offshore wind.
  2. The Salamander project will contribute to the Scottish Government and UK Government net-zero targets. The project can contribute to the Scottish government’s target of 11 GW of installed offshore wind by 2030, as well as the UK government’s target of 5 GW of operational floating offshore wind by the same date.
  3. We are dedicated to developing a sustainable and transformative project, working with the oceans, and enabling communities to benefit from Project Salamander. Therefore, we commit to having a continuous and strong stakeholder and community engagement.

It appears to me, that the Salamander project will be a pathfinder for the 11.1 GW of floating wind farms to be built off Peterhead.

Bringing The Electricity South

National Grid are building four interconnectors between Eastern Scotland and Eastern England.

  • Eastern Green Link 1 – Torness and Hawthorn Pit
  • Eastern Green Link 2 – Peterhead and Drax
  • Eastern Green Link 3 – Westfield and Lincolnshire
  • Eastern Green Link 4 – Peterhead and Lincolnshire

Note.

  1. All interconnectors are 2 GW.
  2. All interconnectors are offshore for a long part of their route.
  3. It also appears that National Grid are burying much of the onshore sections.

But the 4 GW of interconnectors will only be able to bring a quarter of the offshore electricity generated in the Peterhead area to the South.

What Will Happen To The Excess Electricity?

Consider.

  • There could be 16 GW of planned offshore wind power around Peterhead and North-East Scotland.
  • There is only 4 GW of interconnector capacity between Peterhead and Eastern England.
  • There is another 6.8 GW of electricity around North-West Scotland.
  • There is 2.8 GW of electricity being developed to the East of Shetland.
  • The Crown Estate is thinking of increasing the size of some offshore wind farms.

It is likely, that other wind farms will be built in the seas around the North of Scotland.

It appears that the North of Scotland could have at least 20 GW of excess electricity.

Possible solutions would include.

  • Developing energy intensive industries like metal refining.
  • More interconnectors to Denmark, England, Ireland and Norway.
  • Storage of the electricity in giant pumped storage hydroelectric power stations.
  • Creation of green hydrogen for export.

Note.

  1. Aluminium refining has been developed in the North of Scotland before.
  2. More interconnectors are a possibility, especially as Scotland is developing cable manufacturing capacity.
  3. Some maps show extra interconnectors between West Scotland and Merseyside.
  4. At least 70 GWh of pumped storage hydroelectric power stations are being developed along the Great Glen.
  5. I suspect that the pumped storage hydroelectric power stations could be connected to the wind farms, by cables under the waters of Loch Ness.

But surely, production of green hydrogen for export would be a very good way to go.

  1. Extra electrolysers could be added as required.
  2. Because of the interconnectors down both East and West Coasts, electrolysers could be built in England, where there is a large need for hydrogen.
  3. Hydrogen would be exported initially by tanker ships.
  4. At some point in the future, it might be viable to build a hydrogen pipeline to connect to the growing European hydrogen network.

The giant pumped storage hydroelectric power stations and the hydrogen electrolysers would be sized to make sure, that no wind power is never wasted.

Conclusion

The 100 MW Salamander floating wind farm may only be small, but it will prove the technology, the manufacturing and the supply chains, so that Scotland can have a second energy boom from the North Sea.

But this boom will certainly last longer than a hundred years.
