Deal Worth £12bn Announced To Build Offshore Wind Farms
The title of this post is the same as that of this article on the BBC.
This is the sub-heading.
A £12bn deal to construct wind farms has been described by Prime Minister Andy Burnham as “a vote of confidence for building in Britain”.
These two paragraphs add more details.
Energy company RWE and investment firm KKR have announced the funding, which will deliver the Vanguard West and Vanguard East offshore wind farms off the Norfolk coast.
The wind farms are expected to be fully commissioned in 2030, with offshore construction scheduled to begin in early 2027.
These two paragraphs give Andy Burnham’s view.
“It is great news for billpayers because every turbine we put up is power under British control, not at the mercy of events on the other side of the world,” added Burnham, as he prepared to head to the Cop31 climate summit.
“With coastal communities from Scotland to East Anglia powering Britain’s future, the places that host this energy benefit from the jobs and opportunities that it brings,” he added.
But I’m not sure that all the small print has been disclosed yet.
These are my thoughts.
Germany’s Energy Problems
Germany’s energy problems are that they don’t have enough energy and in particular the don’t have enough green energy.
- Twenty percent of their electricity comes from coal.
- Some of that is even the ultra-filthy brown coal.
- They have closed down all their nuclear stations.
- In 2025, they imported 22 TWh of electricity.
But they do make good electrical generators, wind turbines and other electrical equipment.
This map shows the Exclusive Economic Zones (EEZ) around the UK.
Note.
- The UK EEZ is shown in light blue.
- The Irish EEZ is shown in mauve and marked IE.
- The small German EEZ is marked DE.
- Undoubtedly, the rules by which EEZs were drawn, favoured the UK, and countries like Belgium and Germany didn’t do as well.
- The area of the UK’s European EEZ is twenty-three times that of Germany’s whole EEZ, which also includes an area of the Baltic Sea.
- Belgium doesn’t do well compared to The Netherlands.
- There is a substantial area between the UK and Ireland, which can deliver energy to where it is worth more.
- Great Britain and Ireland are surrounded by a large area, that must be worth developing.
- There is a convenient corridor, that runs North-West from the German EEZ to the UK EEZ, which could be used to deliver energy to Germany.
Didn’t the UK (and the Irish) do well!
But the Germans are running out of space to put new offshore wind farms, in their small EEZ.
The Two-Pronged German Solution
The first part of their solution, is to create a gas network called H2ercules that will bring hydrogen to any power station and industry, that needs it from the deep-water port of Wilhelmshaven in North-West Germany, where they would import or generate the gas.
Their first plan to bring green hydrogen to Germany, by creating it in the Namibian deserts using solar panels and wind turbines. It would then be transported to Germany as green ammonia in tanker ships and then converted back to hydrogen.
Unsurprisingly, it never got very far.
Finally, they settled on AquaVentus, which is a system of pipes and wires, that uses wind power in the North Sea to create green electricity, which can also be turned into green hydrogen, which is then brought to Wilhelmshaven in Germany to feed H2ercules.
AquaVentus has planned legs to Denmark, Norway and The Netherlands, and North-East Scotland and Humberside in the UK.
In countries like Denmark, Norway and the UK, we will use AquaVentus to send our surplus electricity to Germany.
The Location Of The Norfolk Wind Farms
This map from RWE shows the Norfolk wind farms.
Note.
- The Norfolk Zone consists of three wind farms; Norfolk Vanguard West, Norfolk Boreas and Norfolk Vanguard East.
- The three wind farms are 1.4 GW fixed-foundation wind farms.
- In Vattenfall Selects Norfolk Offshore Wind Zone O&M Base, I describe how the Port of Great Yarmouth had been selected as the O & M base.
- Great Yarmouth and nearby Lowestoft are both ports, with a long history of supporting shipbuilding and offshore engineering.
- Great Yarmouth and Lowestoft both have a good rail connection to London.
- The Sizewell nuclear power complex is a few miles down the cost just North of Aldeburgh.
- Sizewell C is using hydrogen to minimise the carbon dioxide emissions from construction.
From my knowledge of the area and tales from bringing home North Sea Oil and Gas, I would feel, that the three Norfolk projects wouldn’t be the most difficult of large wind projects to undertake.
The Location Of Wilhelmshaven
This Google Map shows the location of Wilhelmshaven in North-West Germany.
Note.
- Bremen is in the South-East corner of the map.
- Bremerhaven is to the North of Bremen.
- Hamburg is off the map to the East.
- Note the islands along the coast, which feature in the Riddle of the Sands.
- Groningen in The Netherlands is in the South-West corner of the map.
Wilhelmshaven is picked out in red.
This larger map shows the sea and coasts between Hull and Bremen.
Note.
- Bremen and Bremerhaven are in the North-East corner of the map.
- Wilhelmshaven is a dozen miles West of Bremerhaven.
- The red arrow to the North of Norwich on the Norfolk Coast is where the Norfolk Vanguard cables will make landfall at Happisburg.
- Norfolk Boreas cables will make landfall at South Happisburg.
- Hull is in the North-West corner of the map.
From the map, it does appear to me, that the a cable between Humberside and Wilhelmshaven could possibly be routed via the Norfolk wind farms.
Connecting The Norfolk Boreas and Vanguard Wind Farms To The Grid
Google AI gave me this answer.
The Norfolk Boreas and Norfolk Vanguard offshore wind farms (owned and developed by RWE after acquiring the Norfolk Offshore Wind Zone from Vattenfall) connect to the UK National Grid via a major High Voltage Direct Current (HVDC) transmission system:
Landfall Point: Power comes ashore via subsea export cables at Happisburgh on the coast of North Norfolk.
Onshore Cable Route: Electricity is transmitted inland through a 60 km underground cable corridor running across three local authority areas (North Norfolk, Broadland, and Breckland District Councils).
Grid Connection Substation: The underground cables lead to an onshore converter and substation infrastructure adjacent to the Necton substation in Breckland, where it ties into the UK’s National Grid.
Technology & Ownership: The projects use HVDC technology for long-distance transport to minimize environmental and visual impact on the Norfolk countryside compared to overhead lines, backed by multi-billion-pound funding agreements involving RWE and the National Wealth Fund.
My only worry, is will the Norfolk Nimbys allow the 60 km. underground cable to be built?
What Is An Offshore Hybrid Asset?
Google AI defines an Offshore Hybrid Asset like this.
An Offshore Hybrid Asset (OHA)—formerly known as a Multi-Purpose Interconnector (MPI)—is a dual-function subsea power infrastructure that combines offshore wind farm transmission with cross-border electricity interconnection.
How They Work
Instead of individual wind farms building separate dedicated cables to the shore, and countries running point-to-point interconnectors separately, an OHA merges both functions.
Key Examples of Offshore Hybrid Assets
LionLink: A first-of-its-kind OHA project connecting Dutch offshore wind farms (via the TenneT Nederwiek 3 platform) to the Great British grid (landing in Suffolk), providing up to 1.8–2 GW of clean electricity and cross-border trade between the UK and the Netherlands.
Nautilus: A project connecting Belgian offshore wind generators—including links routed via Princess Elisabeth Island (PEI) and the Modular Offshore Grid 2 (MOG2)—to the Great British grid (landing at the Isle of Grain in Kent), delivering up to 1.4 GW of shared wind and interconnector capacity between the UK and Belgium.
Other Integrated Marine Concepts: In a broader renewable context, hybrid marine prototypes combine diverse sources like floating offshore wind with marine solar, or pair ocean wave energy converters with offshore storage and green hydrogen production.
I can see Offshore Hybrid Assets, developed extensively in the future.
GriffinLink
In February 2026, in National Grid, TenneT Germany Launch GriffinLink, A First Of A Find Project To Maximise Offshore Wind, I introduced GriffinLink which was being proposed as a Multi-Purpose Interconnector between the UK and Germany.
Consider.
- The Germans are building electrolyser capacity at Wilhelmshaven in North-West Germany of up to 1 GW.
- I estimate that from Norfolk Boreas wind farm to Wilhelmshaven is 230 miles.
- The Langeled pipeline is a 725 miles between Norway and UK.
- The Viking Link is a 475 mile electrical interconnector between Denmark and the UK.
- Neuconnect is a 460 mile interconnector between the Isle of Grain and Wilhelmshaven.
I believe that despite the distances involved, that the GriffinLink could be an Offshore Hybrid Asset between Happisburg in Norfolk and Wilhelmshaven in Germany.
- It would connect to the three Norfolk wind farms.
- There would be 230 mile electrical connection to Wilhelmshaven.
- There would be 45 mile electrical connection to Happisburg.
- If both electrical connections were 2 GW, then if the three wind farms were at the full total output of 4.1 GW, there would almost be enough capacity to keep all wind farms generating at full capacity.
- It is known that RWE are developing offshore electrolysis and any spare electricity generated in the Norfolk wind farms could be used to create hydrogen.
- Any hydrogen would be stored or sent to Wilhelmshaven in a pipeline.
But Vanguard West and East would be fully operational until 2030, so Germany would have a couple of years of slack in which to build the hydrogen generation, storage and transfer infrastructure.
In What Are Offshore Hybrid Assets?, I describe the concept.
- It would allow hydrogen and electricity to be sent as required to Norfolk or Germany.
- Infrastructure in the two countries could be sized appropriately.
- Hydrogen could be generated offshore
- I believe that batteries could be placed offshore with the wind farm.
- More wind farms could be added.
I can see Offshore Hybrid Assets, developed extensively in the future.
EU Deal Means Return Of Pet Passports For Dogs, Cats And Ferrets
The title of this post is the same as that of this article in The Times!
This is the sub-heading.
New rules will be ratified at a summit on November 20 at which Britain must juggle trade-offs to gain access to Europe’s car and energy markets
I don’t care about dogs, cats and ferrets, provided everybody treats them right and allows me to say hello occasionally, but I do care about energy.
In my opinion the most important paragraph in the article is this one, which introduces, what it will mean for energy in the EU and the UK.
In a separate negotiation, the EU is calling on the UK to pay into European development funds if British energy companies are to gain the freedom to trade in the EU’s single market for electricity. Brussels would stipulate that British taxpayers’ money be funnelled into projects to build roads, airports and green energy facilities in the bloc’s poorer member states.
It might mean, that we have to pay some money in, but we are sitting on one of the largest green energy resources in Europe.
This map shows the The Exclusive Economic Zones (EEZ) around the UK.
Note.
- Undoubtedly, the rules by which EEZs were drawn, favoured the UK, and countries like Belgium and Germany didn’t do as well.
- The area of the UK’s European EEZ is twenty-three times that of Germany’s whole EEZ, which also includes an area of the Baltic Sea..
- Belgium doesn’t do well compared to The Netherlands.
- There is a substantial area between the UK and Ireland, which can deliver energy to where it is worth more.
- Great Britain and Ireland are surrounded by a large area, that must be worth developing.
- There is a convenient corridor, that runs North-West from the German EEZ to the UK EEZ, which could be used to deliver energy to Germany.
Didn’t the UK (and the Irish) do well!
Earlier in my opinion, I considered this paragraph to be the most important paragraph in the article.
In a separate negotiation, the EU is calling on the UK to pay into European development funds if British energy companies are to gain the freedom to trade in the EU’s single market for electricity. Brussels would stipulate that British taxpayers’ money be funnelled into projects to build roads, airports and green energy facilities in the bloc’s poorer member states.
I believe that if we joined the EU’s single market for electricity, this will open up joint UK/EU energy projects.
Energy Supply To The Island Of Ireland
This may be a bit parochial, but it’s important if you live in the Irish Republic or Northern Ireland.
I asked Google AI, the title of this section and received this reply.
The island of Ireland relies heavily on a mix of natural gas, wind power, and energy imports, operating through an all-island wholesale electricity market.
Key Energy Supply Facts
Fossil Fuel Reliance: Ireland remains a net energy importer, with fossil fuels accounting for roughly 79% to 83% of primary energy supply.
Electricity Generation Mix: In recent data, gross electricity supply is led by natural gas (~40%), wind energy (~32%), and net imports (~16%). Coal-fired generation at Moneypoint ended in 2025, and peat-fired generation has phased out or transitioned to biomass.
Single Electricity Market (SEM): The wholesale electricity market operates across the entire island of Ireland (Republic of Ireland and Northern Ireland) as a single pool, managed via the Single Electricity Market Operator (SEMO).
Grid Operators: Transmission systems are operated by EirGrid in the Republic and ESB Networks handling distribution. Interconnections link the island to Great Britain and France.
Demand Drivers: Total electricity demand sits around 34.1 TWh, with commercial services and data centers making up a significant and growing portion of consumption.
Note.
- Energy on the island of Ireland is one of the oldest cross-border energy projects in Europe.
- Sixteen perecent of electricity is imported.
- It appears that electricity in all of Ireland is highly integrated and operates as a single market.
- In What Is The Potential Capacity Of Wind Farms In The Atlantic To The West Of Ireland?, I showed that as much as 600 GW of green electricity could be developed to the West of the island of Ireland.
The island of Ireland has outstanding potential for the development of offshore wind.
How Much Electricity Is Transferred Between The UK And The Irish Republic?
I asked Google AI, the title of this section and received this reply.
The Republic of Ireland and Northern Ireland import approximately 16% of their combined electricity needs from Great Britain.
Interconnectors Between Britain and Ireland
The power exchange happens via subsea high-voltage direct current (HVDC) and AC interconnections:
East-West Interconnector (EWIC): Connects Portan (County Meath, Ireland) and Shotton (North Wales) with a capacity of 500 MW.
Greenlink Interconnector: Connects Great Island (County Wexford, Ireland) and Pembroke (Wales) with a capacity of 500 MW (operational since early 2025).
Moyle Interconnector: Connects Scotland and Northern Ireland with a capacity of 500 MW (Northern Ireland shares an all-island Single Electricity Market with the Republic of Ireland).
North-South Interconnector: Links the grids of Northern Ireland and the Republic of Ireland (capacity around 540 MW).
It would appear that the UK grid and the two grids on the island of Ireland are well-connected.
Would There Be Advantages If Both The UK And The Irish Republic Were In The Same EU Single Market For Electricity?
I asked Google AI, the title of this section and received this reply.
Re-aligning or fully coupling the UK and the Irish Republic within the EU single market for electricity (or the EU’s Internal Energy Market) offers several well-documented economic and operational advantages:
Lower Wholesale Electricity Prices: Post-Brexit decoupling between Great Britain and the island of Ireland’s Single Electricity Market (SEM) caused wholesale electricity prices in Northern Ireland to be up to 20% higher. Recoupling helps lower consumer bills by restoring efficient cross-border trade.
More Efficient Use of Interconnectors: Market coupling links electricity markets across interconnected regions so that prices and power flows are set simultaneously via shared algorithms, allowing electricity to move seamlessly from lower-cost areas to higher-cost ones.
Enhanced Security of Supply: Larger integrated electricity networks make local grid problems easier to manage by enabling immediate energy imports from neighboring systems when a plant trips or demand spikes.
Reduced Reserve Requirements: Operating across a larger, unified grid lowers the total amount of spinning or standby generation reserves needed to maintain stable system performance, since a single plant outage has a smaller relative impact.
Better Integration of Renewable Energy: Greater interconnection prevents the wasteful curtailment of wind and solar farms during high-generation periods, letting regions export surplus green power and maximize environmental and economic returns.
Wind farms could also be built between the two islands with the ability to send electricity where it was needed most.
Would A Combined EU/UK Single Market For Electricity Encourage Cross-Border Energy Projects?
I asked Google AI, the title of this section and received this reply.
A combined EU/UK single market for electricity would significantly encourage cross-border energy projects by removing administrative bottlenecks, optimizing physical infrastructure, and reducing system costs.
Key Ways Integration Encourages Cross-Border Projects
Day-Ahead Market Coupling: Reconnecting Great Britain to the EU’s day-ahead market-coupling system restores automated pan-European optimization for electricity flows. According to the EU Agency for the Cooperation of Energy Regulators (ACER), integrated trading lets countries seamlessly share generation, storage, and demand-side flexibility, which directly supports investments in new interconnectors.
North Sea Hybrid and Offshore Projects: The UK and EU share massive ambitions for North Sea offshore wind (targeting up to 300 GW by 2050). A unified market framework creates the regulatory alignment, carbon pricing clarity (such as linking the UK and EU Emissions Trading Systems), and long-term investor confidence needed to finance multi-country grid links and hybrid wind projects.
Reduction of System Inefficiencies: Current post-Brexit trading arrangements lead to sub-optimal use of interconnector capacity (roughly 12–14 GW). Reintegration is estimated to eliminate annual system inefficiencies worth £120 million to £370 million, making cross-border commercial cases much stronger for developers.
Context and Trade-Offs
Financial and Political Conditions: Discussions and draft proposals (including reports around potential UK contributions to EU development or regional funds in exchange for access) highlight that market re-entry involves political and financial trade-offs for both sides.
Broader Alignment: Analysts note that while full market coupling lowers wholesale power costs and improves grid balancing, its ultimate success depends on avoiding new non-tariff or carbon-border friction (like unaligned Carbon Border Adjustment Mechanisms) that could offset green export gains.
It would appear that on balance a combined EU/UK single market for electricity would encourage cross-border projects and would.be beneficial.
Could A Combined EU/UK Single Market For Hydrogen Work?
I asked Google AI, the title of this section and received this reply.
A combined EU/UK single market for hydrogen could work economically and technically, driven by shared resources in the North Sea and complementary supply-and-demand needs, but faces major political and doctrinal hurdles.
Economic and Technical Potential
Shared Infrastructure: Collaborating on North Sea renewable power generation, hydrogen pipelines, and carbon capture and storage (CCUS) can significantly cut project costs and improve financial backing.
Regulatory Alignment: Both the UK and the EU are implementing Carbon Border Adjustment Mechanisms (CBAM) that cover hydrogen imports by 2027 to prevent carbon-leakage. Harmonizing standards avoids expensive compliance duplication.
Supply and Demand at Scale: The EU has set massive renewable hydrogen targets through REPowerEU, while the UK aims to scale its own domestic capacity (though facing domestic policy and delivery delays).
Political and Institutional Obstacles
The “Indivisibility” Doctrine: The European Commission has previously assessed that deep energy market linkages of this nature run counter to the EU’s core doctrine of the indivisibility of the single market.
Red Lines on Bureaucracy: UK policymakers remain cautious about accepting EU oversight or rejoining Brussels regulatory bodies, while EU officials resist allowing the UK to “pick and choose” cherry-picked single-market access outside of full membership.
Current Frameworks: Post-Brexit trade relies on the Trade and Cooperation Agreement, which lacks deep, permanent integration for emerging clean-energy sectors, though both sides have signaled intent to hold technical and regulatory exchanges on hydrogen and clean tech.
I feel that if the single market can be made to work for electricity, it can be made to work for hydrogen.
Is This Healey’s Magic Money Tree?
It looks to me that Healey has found a Magic Money Tree, which does the following.
- Saves the welfare budget.
- Allows him to abolish standing charges on gas bills.
- Allows him to take VAT off electricity bills.
- Allows him to give £100 to 20,000,000 householders.
- The Kyiv Independent has a headline of UK Announces ‘Biggest Ever’ Ukraine Support Package Of $13 Billion In 2027.
- He seems committed to increasing defence spending.
- Setting up the National Agentic Security Unit will cost millions.
Is this the Magic Money Tree?
- Jackdaw’s gas goes to St. Fergus as planned!
- One leg of AquaVentus, which is a German system of pipes and wires, that brings green hydrogen and electricity from around the North Sea to Wilhelmshaven could start at the St. Fergus Gas Terminal.
- Other legs of AquaVentus are planned to start in Denmark, Norway and The Netherlands.
- Two H2 molecules can be extracted from each gas molecule, as methane is CH4.
- One way is a process called HiiROC that was developed in Hull, which is backed by big names including Cemex, Centrica, Hyundai, INEOS, Kia and Melrose.
- HiiROC is five times more energy efficient than traditional electrolysis.
- The Aberdeen area is not short of green electricity, given the large number of offshore wind farms.
- Germany gets the hydrogen to decarbonise, through the pipes of AquaVentus.
- The wires of AquaVentus could also take green electricity to Germany.
- Germany has run out of space in their Exclusive Economic Zone (EEZ) for more turbines.
- But as our EEZ is 23 times the size of Germany’s, we have enough to rent out space for German wind turbines.
- The route of AquaVentus will use the UK EEZ and could export energy from existing and planned UK wind farms.
- When the EEZs were drawn up, a corridor was left between the German and UK zones, where pipes and wires could be laid to transfer energy between the two countries.
- Burnham visited Merz a few weeks ago and nothing was said about energy to the media.
- But did they put together an energy deal to give Germany the green energy it needs?
- Chris O’Shea is CEO of Centrica and has several professional connections to Burnham from his Manchester days and the recent Labour Conference.
If Germany should be getting all this green energy, Healey will surely be getting loadsaeuros in return.
These are some further thoughts.
EEZ Of The UK And Neighbouring Coastal States
If you like to know more about EEZs or Exclusive Economic Zones, they have a Wikipedia entry, which includes these two statements.
- The idea of allotting nations’ EEZs to give them more control of maritime affairs outside territorial limits gained acceptance in the late 20th century.
- It was not until 1982 with the UN Convention on the Law of the Sea that the 200 nautical mile exclusive economic zone was formally adopted.
This is possibly, the most significant map concerning the future of the UK.
Note.
- The UK EEZ is shown in bright blue.
- The UK EEZ was setup by David Cameron’s government in 2014.
- Much of the UK EEZ stretches a full 200 nautical miles from the coast.
- Germany’s EEZ is indicated by DE.
- The UK EEZ is 23 times the size of Germany’s.
- There is a narrow corridor between the UK and German EEZs, which goes between the Dutch and Danish EEZs, which was the result of an expensive legal battle and gives Germany access to the North Sea.
- Wilhelmshaven is about in the mid-point of the North-facing part of the German coast.
- But the corridor could most-likely be the route of the Aquaventus pipes and wires system between Aberdeen and Wilhelmshaven via Humberside.
Whichever way you look at it, the UK did incredibly well, when EEZs were allocated.
The Route Of AquaVentus To The UK
This map shows the border between the UK and German EEZs.
Note.
- The North-East corner of Scotland is clearly visible in the North-West corner of the map.
- The corridor between the UK and German EEZs is clearly visible.
- The corridor points at the North-East corner of Scotland.
- Wilhelmshaven is on the round estuary on the German coast.
- AquaVentus has a preferred route via Humberside, which looks feasible.
If an AquaVentus leg ran between the German EEZ and the North-East corner of Scotland, it would be totally in the UK EEZ, which would probably simplify any negotiations.
Could AquaVentus Make Use Of The UK’s Energy Storage?
Consider.
- Various companies are building three or four large pumped storage hydro systems in the Highlands of Scotland.
- There are two large gas storage facilities; Aldbrough and Rough on Humberside, which could be converted to hydrogen storage.
Energy storage would surely add functionality to AquaVentus.
Does Germany Import Nuclear Energy Through Interconnectors?
Germany doesn’t have any nuclear power stations, but does it import nuclear energy?
I asked Google AI, thquestion in the title of this section, and received this answer.
Yes, Germany imports electricity that originates from nuclear power plants in neighboring countries via cross-border high-voltage interconnectors.
Key Facts on Nuclear Imports via Interconnectors
Zero Domestic Generation: Germany completed the shutdown of its last domestic nuclear power reactors in April 2023 and produces zero nuclear electricity locally.
Integrated European Grid: Electricity in Europe flows through a shared, interconnected network based on market prices, supply, and demand rather than national political borders.
Sources of Nuclear Imports: When Germany imports electricity—such as from France, Switzerland, or Belgium—a portion of that power mix comes from nuclear generation.
Rising Import Volumes: Estimates by DataPulse Research via Visual Capitalist indicate that Germany’s estimated nuclear electricity imports rose to roughly 18,313 GWh in 2024 following the complete nuclear phaseout.
It appears that so long as they don’t build any nuclear power stations, it’s OK!
What Will Be The Route Of AquaVentus From Denmark, Norway And The Netherlands?
The exact routes have not been decided, but if you look at the map of the EEZ Of The UK And Neighbouring Coastal States, it appears, that nearly all of the routes of the pipes and wires, will lie within the UK EEZ.
The hydrogen and electricity may have not been generated by the UK, but it has come through our EEV.
It looks to me, that we have those Europeans screwed, glued and tattooed.
Germany Has Run Out Of Space In Their Exclusive Economic Zone For More Wind Farms
So they have come up with a plan, where they rent space in the EEZs of other countries and then bring the energy as either green hydrogen or electricity, back to Germany using the pipes and wires of AquaVentus.
Could Dogger Bank South Wind Farm Be Connected To AquaVentus?
Consider.
- It will be a pair of two 1,500 MW wind farms
- They are two of the furthest East UK wind farms and are not far from the border between the UK and German EEZs.
- They are being developed by German company ; RWE.
- They are currently to be connected to the UK grid at Birkhill Wood in the East Riding of Yorkshire.
But if it were more convenient or affordable could the two wind farms be connected to AquaVentus and send their green energy to Germany?
Conclusion
AquaVentus will bring Germany the energy it needs from around the North Sea.
And Chancellor Healey will have a long-lasting Magic Money Tree.
New North Sea Gas To Flow After Approval For Jackdaw Drilling
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
The first significant British field in almost a decade could begin production by Christmas. The taxes raised will fund ‘clean power’, the chancellor says
These three paragraphs add more detail.
North Sea gas production will increase within weeks after ministers gave approval on Wednesday for drilling in the first big new field in almost a decade.
Miatta Fahnbulleh, the energy secretary, confirmed that Jackdaw, off Aberdeen, has passed a new environmental assessment and will go into production before Christmas.
The field is the UK’s largest known untapped gas reservoir and could account for 6 per cent of North Sea gas production when fully operational.
I will now ask a couple of questions.
How Will Jackdaw’s Gas Get To The UK Gas Grid?
I asked Google AI this question and received this answer.
Gas extracted from the Jackdaw gas field will reach the UK gas network by utilizing existing North Sea energy infrastructure through a multi-stage pipeline connection:
1. Subsea Pipeline to Shearwater: Gas will first flow from the Jackdaw platform through a newly designed 31km subsea pipeline to the nearby, existing Shearwater hub.
2. Transportation Onshore: From the Shearwater platform, the gas and associated liquids will be tied into major existing offshore transmission systems—specifically the Fulmar Gas Line and the Forties Pipeline System.
3. UK Grid Entry: These pipelines route the resources directly onshore to processing facilities, primarily the St Fergus gas terminal in Aberdeenshire, Scotland, where the gas is processed and fed directly into the Great British National Transmission System (NTS).
The project, operated by Adura (a Shell and Equinor joint venture), has received final government approval and is expected to begin supplying the UK grid as early as late October 2026.
What Is Aquaventus?
I asked Google AI this question and received this answer.
AquaVentus is a major German-led energy initiative aimed at producing green hydrogen at scale from offshore wind energy in the North Sea. Managed by the AquaVentus Förderverein e.V.—which is registered on the island of Helgoland with offices in Berlin—the project brings together a consortium of more than 100 international companies, research institutions, and organizations.
The overarching goal of the initiative is to establish 10 gigawatts (GW) of offshore electrolysis capacity by 2035. This capacity is projected to yield roughly 1 million tonnes of climate-neutral green hydrogen per year, providing a critical clean energy source to decarbonize heavy industries, aviation, and maritime shipping that cannot be easily electrified.
Core Architecture & Flagship Projects
The initiative operates through a synchronized value chain broken down into highly specialized sub-projects:
AquaPrimus: A practical demonstrator project testing offshore wind turbines integrated directly with hydrogen production units under real-world sea conditions.
AquaSector: A large-scale offshore hydrogen park intended to prove the commercial and operational viability of scaled-up marine electrolysis.
AquaDuctus: The central “hydrogen backbone” pipeline. Instead of converting electricity to send ashore via traditional subsea cables, this pipeline will collect hydrogen directly from the offshore platforms and transport it straight to the German core grid. It was officially integrated into Germany’s hydrogen core network planning in October 2024.
AquaCampus: A European research and testing platform set up in the North Sea to advance marine electrolysis technologies.
AquaPortus & AquaNavis: Infrastructure projects focused on adapting coastal harbours and developing hydrogen-based maritime shipping applications.
Infrastructure and Partnerships
Rather than relying purely on electricity transmission, AquaVentus champions a combined connection concept. This hybrid infrastructure links offshore wind farms using both traditional power cables and hydrogen pipelines. Depending on fluctuating market electricity prices and real-time demand, wind farms can alternate between feeding electricity directly into the grid or generating hydrogen on-site. The initiative has actively lobbied European regulators to fully anchor these hybrid layouts into offshore wind energy legislation.
The consortium includes major global energy and industrial players like RWE, BP, Shell, TotalEnergies, Ørsted, and Siemens Energy. Furthermore, it continues to scale its international footprint, recently partnering with organizations like Hydrogen Scotland to explore connecting North Sea infrastructure directly into broader European energy markets.
Aquaventus will connect to Norway, Denmark, The Netherlands, and Aberdeen and Humberside in the UK to Wilhelmshaven in Germany.
Could Aquaventus Be Supplied with Scottish Hydrogen?
I asked Google AI this question and received this answer.
Yes, AquaVentus can be supplied with Scottish green hydrogen.
Key Details of the Partnership
Memorandum of Understanding (MoU): AquaVentus (a German-led offshore wind-to-hydrogen initiative) and Hydrogen Scotland signed an agreement to link Scottish offshore wind and hydrogen production into the North Sea energy network.
Shared Infrastructure: The collaboration aims to connect Scotland’s offshore wind potential with cross-border transport concepts like the planned AquaDuctus offshore hydrogen pipeline.
Export Goals: The partnership is designed to establish Scotland as a major green hydrogen supplier to European markets such as Germany, integrating Scottish production into a pan-European hydrogen backbone.
Some electrolysis capacity would need to be built.
Could Jackdaw’s Gas Be Used To Create Hydrogen For AquaVentus?
Consider.
- There will be an Aquaventus connection from Aberdeen to Wilhelmshaven via Humberside.
- Jackdaw is connected to the St. Fergus Gas Terminal, which is less than 40 miles from Aberdeen.
- There are now efficient ways of extracting the four hydrogen atoms of each methane molecule from natural gas.
- There is plenty of green electricity at Aberdeen.
I believe that natural gas from Jackdaw could be turned into hydrogen at Aberdeen and sent to Germany via Aquaventus.
One of the best methods to create hydrogen has been developed by HiiROC.
- HiiROC is a spin-out of Hull University.
- HiiROC’s backers include Melrose Industries, HydrogenOne, Centrica, Cemex, Hyundai and Kia, Wintershall Dea and VNG.
- HydrogenOne is backed by INEOS.
- HiiROC uses a fifth of the energy of traditional electrolysis.
- The HiiROC process, which is called thermal plasma electrolysis, splits any hydrocarbon gas into hydrogen and carbon black.
- Feedstocks can include chemical plant offgas, biomethane and natural gas.
- Carbon black has various uses including manufacturing tyres and rubber products.
- In Hydrogen Milestone: UK’s First Hydrogen-to-Power Trial At Brigg Energy Park, I describe how Centrica and HiiROC have generated electricity at Brigg power station.
- In Cemex To Install World-First Hydrogen Process At UK Cement Plant, I describe how Cemex will use HiiROC to make low-carbon cement at Rugby.
I believe that a large HiiROC electrolyser at Aberdeen could provide enough hydrogen for Aquaventus.
I have some thoughts.
Will Aquaventus Be Using The Albrough And Rough Gas Storage?
I asked Google AI this question and received this answer.
Yes, the broader AquaVentus framework is designed to integrate with British transmission networks and link to underground cavern and reservoir storage assets on Humberside, including the Aldbrough Hydrogen Storage site and Rough Gas Storage.
Key Details
AquaVentus Integration: While the primary focus of offshore German pipelines like AquaDuctus is delivering green hydrogen to Germany, the broader AquaVentus network links into UK transmission systems and regional storage options.
Aldbrough Hydrogen Storage: SSE Thermal and Equinor are developing plans to repurpose and expand the underground salt caverns at the Aldbrough site in East Yorkshire to store low-carbon hydrogen.
Rough Gas Storage: Centrica has explored plans to convert the offshore Rough gas storage field in the North Sea for hydrogen storage as part of the wider regional infrastructure development in the Humber area.
The hydrogen can also be distributed to customers on Humberside.
No, the carbon black created by HiiROC will not be a problem; instead, it is an economically valuable asset and an environmental benefit. Rather than producing gaseous carbon dioxide, HiiROC’s Thermal Plasma Electrolysis (TPE) process locks carbon into a stable, solid carbon black co-product.
The solid carbon black generated by this technology is a solution rather than a problem for several key reasons:
1. It Completely Avoids Carbon Dioxide Emissions
In traditional hydrogen production (like steam methane reforming), carbon is released as gas. HiiROC operates a completely oxygen-free plasma system. Because there is no oxygen, carbon dioxide cannot form. The carbon is instantly cooled and solidified into an inert powder, trapping it permanently so it cannot escape into the atmosphere.
2. It Replaces a Highly Polluting Global Industry
Carbon black is already a massive global commodity used heavily in vehicle tires, plastics, inks, and coatings. However, traditional carbon black manufacturing (the oil furnace process) is notoriously dirty and generates severe greenhouse gas emissions and air pollution. HiiROC’s product serves as a sustainable, zero-emission alternative for these manufacturing chains.
3. It is Highly Marketable and Versatile
Rather than a waste material that requires disposal, HiiROC’s carbon black is being commercialized for various industrial uses:
Automotive: Tokyo Gas and major tire manufacturers are testing and assessing its use for sustainable tires.
Construction & Infrastructure: It is being integrated into building materials like concrete through partnerships with global companies like Cemex.
Agriculture: It can be safely utilized for soil enhancement.
It sounds like HiiROC should be filed under too good to be true.
Is Research Being Undertaken To Find More Uses For Carbon Black?
I asked Google AI this question and received this answer.
Yes, extensive research is actively underway to find and expand new uses for carbon black, particularly in clean energy, advanced electronics, and sustainable manufacturing.
Emerging & Research-Backed Applications
Lithium-Ion Batteries & Energy Storage: Researchers are optimizing carbon black grades as conductive additives and low-cost alternatives to lithium metal in battery cathodes and anodes, as well as use in fuel cells, supercapacitors, and solar cells.
Electric Vehicles (EVs): Manufacturers are developing specialized, high-conductivity carbon black formulations to improve EV tire durability, lightweight polymers, and high-performance battery systems.
Electromagnetic & Conductive Materials: Research explores carbon black in conductive adhesives, electromagnetic interference (EMI) shielding, antistatic flooring, and radar-absorbent materials.
Green & Circular Production Methods: Scientists are investigating alternative manufacturing pathways—such as methane pyrolysis, turquoise hydrogen co-production, and tyre pyrolysis—to create recovered and circular carbon black (rCB) with a significantly lower carbon footprint than traditional fossil-oil burning.
Note.
- The HiiROC process is considered turquoise hydrogen co-production.
- Tyre pyrolysis recovers valuable carbon black by breaking down end-of-life tires (ELTs) at high temperatures (typically 450°C to 600°C) in an oxygen-free environment.
It seems to me that HiiROC could transform an industry.
New Ferry Link Proposed Between Aberdeen And Iceland
The title of this post is the same as that of this article in The Times.
This is the sub-heading.
Talks are under way for a ferry from Aberdeen to Seydisfjordur in eastern Iceland, reviving a North Atlantic connection that endured for 150 years
These three paragraphs add more detail.
There were wild celebrations when the first ever regular mail steamer from Scotland arrived in Iceland.
Cheering crowds gathered as the Clyde-built Victor Emanuel, her single funnel belching black smoke, slipped into Reykjavik harbour in 1858 after crossing the North Atlantic from Leith. It was an historic day, marking a service that was to bind Britain and Iceland in a way they never had been before.
There was little or no emotion, however, when the last regular sea connection between Scotland and Iceland was lost in 2008 amid the rise of low-cost airlines, ending a century and a half of shipping history.
But now it appears that the ferry might be revived, as The Times article reports.
This Google Map shows the seas between Aberdeen and Iceland.
Note.
- Iceland is in the North-West corner of the map.
- Seydisfjordur, which will be the port, where the service will terminate is indicated by the red arrow.
- The Faroe Islands are in the middle of the map.
- Aberdeen is in the South-West corner of the map.
- The Orkneys and Shetlands are North of Scotland.
I was rather surprised, I could get everything on the single map.
This second map shows all the wind farms being developed around the North of Scotland.
Note.
- These seventeen wind farms have a total capacity of 24 GW.
- Currently, in total, as I write this we’re using 35.7 GW and generating 32.9 GW.
- The difference is made up of transfers.
- There are more details on these wind farms in Ørsted, Simply Blue, Subsea7 Submit Application For 100 MW Scottish Floating Wind Farm.
There would appear to be plenty more space for wind farms.
What Will Happen To This Energy In The North Of Scotland?
The Germans have a shortage of green energy and it is likely that they will build a system of pipes and wires called AquaVentus between Aberdeen and Wilhelmshaven via Humberside to bring green hydrogen and electricity to Germany.
I can see a need for ferries linking Wilhelmshaven, Aberdeen, Orkney, Shetland, the Faroes and Iceland, if construction really takes off in the area, where there is one of the largest undeveloped areas in Europe, that is suitable for wind farms.
And much of the area is in the UK EEZ.
I do wonder, if in his recent visit to Merz, Burnham and the German Chancellor agreed to develop the Northern part of the UK EEZ for the mutual benefit of the two countries.
I will finish with these questions.
What Is The Offshore Wind Potential Of Iceland?
I asked Google AI this question and received this answer.
Iceland possesses massive theoretical offshore wind resources, estimated by the World Bank at approximately 847 gigawatts (GW), which is more than the combined potential of countries like France and Spain.
Key Aspects of Iceland’s Offshore Wind Potential
Resource Scale: The World Bank estimates Iceland’s coastal waters could yield up to 847 GW of power, far exceeding the country’s domestic electricity consumption (which is currently met almost entirely by geothermal and hydroelectric power).
Geographical and Climate Challenges:
Shallows and Coastline: Unlike shallow North Sea basins, Iceland’s rugged coastlines have relatively few shallow areas, which can complicate conventional fixed-bottom turbine installations.
Harsh Conditions: Winter wind speeds and power densities are exceptionally high (with offshore values exceeding 1,000 W/m² in southern, eastern, and western coastal areas), though extreme weather, tectonic activity, and volcanic-glacial sediments require specialized foundation engineering.
Export and Cross-Border Concepts: Because Iceland’s domestic energy needs are already satisfied by low-cost renewables, large-scale offshore wind developments are often proposed for export. For example, developers like Hecate Independent Power (HIP Atlantic) have explored multi-gigawatt offshore wind projects off Iceland’s coast linked directly to the United Kingdom via long-distance subsea HVDC transmission cables.
Emerging Research: Scientific bodies like the British Geological Survey (BGS) and the Icelandic Geological Survey (ÍSOR) have partnered on grants to map Iceland’s seabed and glacial outwash plains to better evaluate site suitability and turbine foundation designs.
Iceland could be Europe’s largest power station.
It’s lucky Trump has no engineering, mathematical or scientific knowledge, otherwise he’d be jealous.
What Is The Offshore Wind Potential Of The Faroe Islands?
I asked Google AI this question and received this answer.
The Faroe Islands possess substantial wind resources, though deep surrounding waters present engineering challenges for standard bottom-fixed offshore wind turbines. To bypass these constraints and overcome local onshore resistance (“NIMBY” opposition), the territory has actively explored and planned offshore installations:
Planned Offshore Wind Projects
Tórshavn Offshore Wind Farm: The Faroese power company SEV planned an initial offshore wind project near the capital, Tórshavn, sized between 96 MW and 120 MW.
Replacement of Onshore Plans: This single offshore initiative was designed to replace at least five delayed or contested onshore wind farms, accelerating the territory’s push toward its goal of 100% sustainable electricity generation by 2030.
Technical & Geographical Challenges
Deep Waters: Standard fixed-bottom offshore wind turbines are difficult or costly to deploy because the waters surrounding the steep volcanic islands become deep very quickly.
Alternative Approaches: Studies and strategies have investigated floating offshore wind options, as well as integrating offshore wind with green hydrogen and ammonia production to power local maritime and industrial sectors.
Tidal Complement: Because standard wind and solar can be variable or affected by harsh salt and wind conditions, the islands are heavily supplementing their wind strategy with predictable underwater tidal kite technology (such as Minesto systems) which hold a separate 2 GW national tidal potential.
It looks like The Faroes goal of 100 % sustainable electricity generation by 2030, will mean they won’t be exporting large amounts of energy.
What Is The Offshore Wind Potential Of The Shetland Islands?
I asked Google AI this question and received this answer.
The Shetland Islands possess some of the most consistent and high-capacity wind resources in Europe, with multi-gigawatt offshore wind potential supported by ScotWind leasing rounds.
Key Offshore Wind Projects & Potential
Arven Offshore Wind Farm: A major floating offshore wind project targeted for the early 2030s located east of Shetland. It features a planned capacity of 2.3 GW (enough to power roughly 2 million homes annually).
Stoura Offshore Wind Farm: An early-stage floating wind project awarded to ESB via Crown Estate Scotland’s ScotWind process. Located about 40 km east of Shetland, it has a targeted capacity of 500 MW.
NE1 Site & Regional Leasing: The broader waters surrounding Shetland have yielded licensing for roughly 2.8 GW to 3 GW or more of offshore floating wind capacity through recent leasing rounds, utilizing deep-water floating technology for depths exceeding 60 meters.
Complementary Energy Infrastructure
Onshore Integration: The massive 443 MW Viking Energy Wind Farm (103 turbines) and related onshore sites operate alongside a 260 km subsea HVDC interconnector cable linking Shetland directly to the UK mainland grid.
Industrial Transition: The historic Sullom Voe Terminal is shifting into a clean energy and carbon storage hub (via projects like Veri Energy and ORION), exploring how excess offshore and onshore renewable power can drive green hydrogen production and offshore platform electrification.
Local Challenges: Developers and authorities must balance this massive marine energy potential with spatial constraints, local fishing industry concerns, and grid-connection capacities.
Shetland seems to have implemented an excellent local solution.
What Is The Offshore Wind Potential Of The Orkney Islands?
I asked Google AI this question and received this answer.
The Orkney Islands possess massive offshore wind potential, with surrounding regional waters estimated to hold anywhere from 5 GW to over 17 GW of immediate local generation capacity, alongside broader island and northern Scottish shelf sharing over 100 GW of combined offshore wind potential.
Key Offshore Wind Scale & Figures
Immediate/Local Potential: Between 5 GW and 10 GW of generation capacity lies within 12 miles of the islands, with broader regional models citing up to 17,000 MW (17 GW) of nearby offshore wind potential.
Broader Northern Potential: Orkney—alongside Shetland and the Outer Hebrides—shares access to a regional pool exceeding 100 GW of offshore wind capacity.
Major Projects: The landmark West of Orkney Windfarm (located 30 km off the west coast) features a capacity of 2 GW (up to 125 fixed-foundation turbines), designed to power over 2 million homes and target initial power generation around 2030. It is the first ScotWind project to secure both offshore and onshore planning consents.
Infrastructure & Grid Challenges
Grid Bottlenecks: Orkney frequently generates more than 130% of its local power needs from renewables, leading to significant wind curtailment because legacy interconnector cables to the Scottish mainland are heavily constrained (limited to roughly 40 MW).
Upcoming Upgrades: A new major transmission interconnector cable project is slated to scale up export capacity and relieve these constraints by the end of 2028.
Ports and Supply Chain: Strategic port developments—such as the Scapa Deep Water Quay project at Scapa Flow—are receiving multi-million-pound investments to transform Orkney into a primary assembly, manufacturing, and maintenance hub for Scottish and European floating and fixed offshore wind farms.
It appears that the priority is better transmission of the generated electricity.
Conclusion
It looks like a substantial amount of green electricity can be harvested and brought South, either as electricity or as green hydrogen.
UK And Germany Will Face Threats Together, Says Burnham In Berlin
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
The UK and Germany will face threats together, Prime Minister Andy Burnham has said as he reaffirmed a series of defence and security partnerships
These two paragraphs add some more detail.
On his first official European trip, apart from visits to Ukraine, Burnham met German Chancellor Friedrich Merz, and was greeted with military honours in Berlin.
Speaking to reporters at the German capital’s Federal Chancellery, the prime minister said both countries were facing hybrid attacks “on a regular basis” and “it makes sense” to take them on together.
I am surprised that the article doesn’t mention energy, as it is a problem for both Germany and the UK.
Germany’s problems include.
- They are short of both green electricity and gas.
- They produce about a fifth of their electricity from coal.
- They have weaned themselves off Russian gas and nuclear power.
- They have poor electricity storage.
Their strengths include.
- Siemens is the second-largest European wind turbine manufacturer.
- 29 wind farms in the UK, have been built around Siemens wind turbines.
- RWE is a major German developer of wind farms.
- RWE is the largest generator of electricity in the UK.
- RWE own or part-own thirteen wind farms in the UK.
Germany also has good plans to solve their problems.
- AquaVentus is a series of pipes and wires to bring green electricity and hydrogen from Norway, Denmark, the Netherlands, and Aberdeen and Humberside in the UK. to Wilhelmshaven in North-West Germany.
- H2ercules is a plan to deliver hydrogen around Germany to power industry.
In New Study Shows How North Sea Offshore Wind Can Yield More While Costing Less, I found this “It appears from the text in this must read report, that the Germans might develop as much as 20 GW in neighbouring countries.”
The UK’s problems include.
- High electricity and gas prices.
- Not enough electricity storage.
- Poor connections to the grid.
Our strengths include.
- A large amount of solar and wind power is being developed.
- We will generate more electricity than we need.
- Geographically, we generate more electricity on the East side of the UK, so our electrons are ideally placed in invade Germany.
- We shall be able to send electricity and hydrogen to Germany using the AquaVentus system.
- We are developing at least three 2 GW/30 GWh pumped storage systems in Scotland to store electricity and back up AquaVentus.
- Rough and Aldbrough are gas storage reservoirs on Humberside, that could be converted to store hydrogen, so we could keep Germany supplied.
- HiiROC is affordable hydrogen production technology being developed in Hull, which is five times more efficient, than traditional methods.
Centrica is backing HiiROC and is developing a stable of British ideas.
The UK’s Biggest Advantage
This map shows the The Exclusive Economic Zones (EEZ) around the UK.
Note.
- Undoubtedly, the rules by which EEZs were drawn, favoured the UK, and countries like Belgium and Germany didn’t do as well.
- The area of the UK’s EEZ is twenty-three times that of Germany’s EEZ.
- Belgium doesn’t do well compared to The Netherlands.
- There is a substantial area between the UK and Ireland, which can deliver energy to where it is worth more.
- Great Britain and Ireland are surrounded by a large area, that must be worth developing.
- There is a convenient corridor, that runs North-West from the German EEZ to the UK EEZ, which could be used to deliver energy to Germany.
Didn’t the UK (and the Irish) do well!
I believe that there are joint actions that the UK and Germany can take to both their own advantages.
Find A Way To Keep Rough Operational
If we keep Rough operational, then.
- It can usefully act as hydrogen storage for the Germans, with a connection to AquaVentus.
- We can also use it as a store for hydrogen created from excess energy, when we have too much.
- It can also supply hydrogen to companies like INEOS on Humberside.
- Hydrogen could also be exported from the Port of Hull in small coastal liquid hydrogen tankers.
- Companies that need a lot of zero-carbon energy could move to Humberside.
I suspect John Healey will make an announcement in the 2026 Budget.
AquaVentus And Energy Storage
AquaVentus, the pumped storage hydro in Scotland and the hydrogen storage on Humberside could make a big difference to the cost of UK energy, as instead of paying wind farm operators to turn off their wind farms, the excess electricity be handled in one of these ways.
- It can be sent to Germany using AquaVentus as electricity.
- Electricity can be stored in the pumped storage hydro in the Highlands.
- It can be used to create hydrogen which can be stored in Rough and Aldbrough.
- Hydrogen can be sent to Germany using Aquaventus.
- Electricity waste is minimised, which saves the UK money.
- Germany gets a more reliable supply of green hydrogen.
The UK should get a cash flow from Germany for the energy, that is delivered.
AquaVentus Could Be Combined With National Grid’s Eastern Green Links Project
Consider.
- AquaVentus will bring energy from Aberdeen and Humberside to Wilhelmshaven.
- National Grid are building five Eastern Green Links along the East Coast of the UK to move electricity to where it is needed.
- EGL1 will link Murton, Co Durham and Torness.
- EGL2 will link Drax, Yorkshire and Peterhead.
- EGL3 will link Anderby Creek and Peterhead.
- EGL4 will link Anderby Creek and Westfield, Fife.
- EGL5 will link Anderby Creek and Peterhead.
- All willhave a capacity of 2 GW.
The Eastern Green Links have a Wikipedia entry.
This Google Map shows the location of Wilhelmshaven with respect to the UK.
Wilhelmshaven is marked by the red arrow.
- It looks to me, that between Lincolnshire and Scotland AquaVentus and EGL1-5 will be following a similar route up the East Coast of the UK, which would surely make construction easier, faster and less costly.
- Provision could easily be made to provide a link to the Sizewell nuclear site, which has a total capacity of 4.4 GW.
- NeuConnect is a 1.4 GW interconnector between the Isle of Grain and Wilhelmshaven, that is under construction and will be 725 kilometres long.
- On the Isle of Grain is the 1.32 GW gas-fired power station, that is owned by RWE.
- BritNed is a 1 GW interconnector between the Isle of Grain and Rotterdam.
- Nemo Link is a 1 GW interconnector between Kent and Zeebrugge.
- LionLink is a proposed 1.8GW HVDC electrical interconnector to link offshore wind farms in the North Sea to the electrical grids in both Great Britain and the Netherlands.
- In National Grid, TenneT Germany Launch GriffinLink, A First Of A Find Project To Maximise Offshore Wind, I talk about GriffinLink, which will run between the UK and Germany.
I wouldn’t be surprised to see a tidying-up of the electrical connections between England, Belgium, The Netherlands and Germany.
Are the Danish And German Grids Connected Under The North Sea?
I asked Google AI this question and received this answer.
The Danish and German electricity grids are connected through undersea and land infrastructure, though direct grid-to-grid interconnections under the North Sea itself are currently expanding rather than existing as a direct bilateral link between the two countries’ mainland grids.
Current and Planned Connections
Land Boundary: The primary connection between Denmark and Germany is a shared 146-kilometer land border across the Jutland peninsula, which carries high-voltage alternating current (HVAC) power lines linking the two national transmission systems.
North Sea Undersea Cables (Indirect/Transit): The COBRAcable, a high-voltage direct current (HVDC) submarine link operated by TenneT and Energinet, connects the electricity grids of the Netherlands and Denmark, running through the German sector of the North Sea.
North Sea Hybrid Projects: German and Danish transmission system operators (such as Amprion and Energinet) have signed agreements and memoranda—including joint declarations from the North Sea Summit—to examine and develop future hybrid offshore wind interconnectors and energy hub links in the North Sea.
Baltic Sea Connections: In contrast, direct cross-border grid and hybrid wind connections between Denmark and Germany are more established or actively deploying in the Baltic Sea, such as through the Kriegers Flak and Bornholm Energy Island projects.
It looks like what is happening between England and Germany has already been developed between Germany and Denmark.
Does Germany Want To Put Wind Farms In Other Countries EEZs And Bring The Energy To Germany?
Google AI gave this answer to my question.
Yes, Germany is moving toward integrating and allowing cross-border and radial offshore wind projects located in the Exclusive Economic Zones (EEZs) of neighboring countries—such as Denmark—to connect directly to the German grid.
Rather than “renting” areas unilaterally, Germany is accomplishing this through joint cross-border European partnerships and bilateral agreements.
Key Details
Regulatory Changes: Germany has proposed amendments (such as via drafts integrating “international offshore connection lines” into its WindSeeG legislation) to explicitly cover radial lines from an offshore farm outside the German EEZ connected exclusively to the German grid.
Counting Toward Targets: These proposed rules allow cross-border radial offshore wind projects to count directly toward Germany’s national offshore wind targets (such as its 70 GW offshore wind goal).
Cross-Border Cooperation: Strategic frameworks—such as between Denmark and Germany—are being established to link projects in foreign waters (like Danish waters) to German converter platforms (e.g., the OST-2-4 platform in the German EEZ).
Research and Industry Push: Studies (including analysis by Fraunhofer IWES) and industry voices (such as Örsted) have argued that shifting or sharing some offshore build-out into neighboring waters like Denmark and Sweden can optimize output, lower costs, and reduce the risk of regionally weak wind conditions. This is also part of broader European agreements like the North Sea Summit declarations scaling up cross-border infrastructure.
Note.
- The UK and German EEZs join via a corridor, that would surely be bideal for a large capacity cable, which is clearly visible on then EEZ map.
- The UK has more than enough space for wind farms.
- The primary source of the UK’s offshore energy could shift to wind farms to the West and North-West of Great Britain.
- Eastern British would probably play a large part in the construction and service of German wind farms to the East of Great Britain.
There would appear to be winners all round.
- Germany gets the energy it needs.
- The UK gets the affordable energy it needs.
- The UK gets paid for the energy created in and exported from its waters.
- British jobs will be created in the construction and support of the German wind farms.
This could be the start of something very big for Germany and the UK.
New Study Shows How North Sea Offshore Wind Can Yield More While Costing Less
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
A less dense development of offshore wind in the German Exclusive Economic Zone (EEZ) of the North Sea, and a relocation of capacities to neighboring countries can both increase the yield from offshore wind and reduce costs, a new study by the Fraunhofer Institute for Wind Energy Systems (Fraunhofer IWES) has shown.
These two paragraphs add more detail.
With Germany’s current expansion target of 70 gigawatts (GW) by 2045 and the planned land use to date, the utilization of offshore wind power will fall far short of its technical potential, the study has shown.
While the North Sea is among the windiest regions worldwide, shading effects would significantly reduce the achievable yield of up to 5,000 full-load hours. Furthermore, the close proximity of wind farms reduces each other’s wind output.
It appears from the text in this must read report, that the Germans might develop as much as 20 GW in neighbouring countries.
In Will A Large Green German Elephant Get Involved In The Clacton By-Election?, I talked about a 2 GW cluster of wind farms being developed by RWE and their partners.
- 1.1 GW – Five Estuaries
- 504 MW – North Falls
- 353 MW – Galloper
Note:
- In total they are around 2 GW.
- The wind farms are around 30 km. offshore from Clacton.
- RWE are a respected German company, who are one of the UK’s largest electricity generators.
I believe that RWE and their partners could receive a lot of opposition to an overhead power line across Essex to connect these wind farms to the National Grid, and 2 GW would not be a small set of pylons.
Would it be a better value project to bring this energy to Germany, either as green electricity or green hydrogen, than connect it to the UK’s National Grid?
Consider.
- A cable between the three wind farms and the nearest part of Germany would be about 300 miles.
- The longest undersea interconnect is the Viking Line between England and Denmark, which is 475 miles long.
- RWE have been building a big offshore electrolyser in The Netherlands called H2OpZee and I believe that similar technology could be used with the Clacton wind farms.
- 2 GW of energy would be ten percent of the energy, that Germany needs.
- I’m sure Rachel from Accounts would be happy for any payments for the energy.
It looks to me that energy links between the UK and Germany will only get more numerous and stronger as the years roll by.
North Sea Exclusive Economic Zones
Out of curiosity, I searched for a map and found this on Wikipedia.
Note.
- Yellow is France.
- Mauve is Belgium, who drew the short straw.
- Light Blue is The Netherlands.
- Black is Germany, who despite their large land area, don’t have as much sea as the UK.
- Red is Denmark.
- Dark Blue is Norway.
- Green is The UK.
Didn’t we do well!
But Belgium and Germany miss out badly, when it comes for virgin sea to fill with wind farms.
Energy Links To Belgium
The UK has developed or is developing two grid links to Belgium.
- Nemo Link – a 1.0 GW interconnector.
- Nautilus – A 1.7 GW offshore hybrid asset.
National Grid is a partner with their Belgian equivalent ; Elia in both.
Energy Links To Germany
Germany is developing.
- NeuConnect – a 1.4 GW interconnector.
- GriffinLink – a hybrid offshore link.
- AquaVentus – In AquaVentus, I outlined this massive German project to bring Hydrogen to Germany from the North Sea.
I believe there will be more links.
Crown Estate To Re-Tender 1.5 GW Offshore Wind Site Relinquished by EnBW And JERA Nex BP
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Crown Estate will launch a competitive tender process next month to bring the 1.5 GW Morgan offshore wind project in the Irish Sea back to market, with plans to appoint a new developer by late 2026.
These two paragraphs add more detail.
The Morgan site was originally awarded through Offshore Wind Leasing Round 4 in 2021, but development was discontinued in January 2026 by the joint venture between EnBW and JERA Nex BP, which held the lease rights.
After EnBW decided to exit the Morgan and Mona offshore wind projects in the UK, its joint venture partner JERA Nex BP acquired EnBW’s stake in 1.5 GW Mona, while the joint venture discontinued the development of the Morgan project and returned the lease rights to the Crown Estate.
There is no Morgan web site, but there is a joint web site with the Morecambe wind farm, which also has its own web site.
The joint web site has a home page showing both Morgan and Morecambe wind farms connecting to Penwortham substation.
In Mooir Vannin Offshore Wind Farm, I say that this web farm will also have a connection to the Penwortham substation.
There does seem a lot of bitterness about using the Penwortham substation being built.
This Ørsted map shows the large number of wind farms in the Irish Sea.
Note.
- Mooir Vannin is a 1.4 GW wind farm being developed to the East of the Isle of Man
- Morgan wind farm would have been a 1.5 GW wind farm to be South of Mooir Vannin.
- Mona wind farm will be a 1.5 GW to the South of Morgan.
- Mona will connect to the North Wales coast.
- Morecambe will be a 480 MW wind farm to the East of Morgan and Mona.
- Mooir Vannin will connect to the Isle of Man.
- Morgan and Morecambe wind farms were all planned to connect to the Penwortham substation.
- Mooir Vannin will additionally connect to the Isle of Man.
It will be interesting to see, what proposals are put to the Crown Estate for a replacement of the Morgan wind farm.
I wouldn’t be surprised to see something to do with offshore production of hydrogen, as there is much more hydrogen production on the East side of the UK, due to the massive German AquaVentus project.
New Baltic Sea Interconnector On Horizon As Lithuania, Latvia, and Germany Plan Cross-Border Link
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Lithuania, Latvia, and Germany are planning a joint offshore interconnector that would enable electricity trading between the Baltic countries and Germany and allow for the integration of up to 2 GW of offshore wind capacity in Lithuania and Latvia
These first two paragraphs add more detail to the article.
The energy ministers of the three countries signed a joint declaration of intent on 18 February, paving the way for the development of the Baltic-German PowerLink interconnector, which would, in addition to electricity trading and offshore wind capacity integration, also enable the expansion of onshore renewable energy capacity.
The Lithuanian, Latvian, and German transmission system operators (TSOs) – Litgrid, Augstsprieguma tīkls and 50Hertz – agreed to assess the feasibility of the hybrid electricity interconnection.
As Germany, has the following connections under development in the West.
- AquaVentus to Aberdeen, Humberside, Denmark, Norway and The Netherlands.
- NeuConnect to the Isle of Grain In England.
- GriffinLink, which is an offshore link to England.
The Germans seem to be putting themselves at the centre of an energy distribution system, that has the capability to stabilise European and UK electricity for thousands of years. Especially, if the network grows to include more countries.
This paragraph says this about the Baltic-German PowerLink project.
The Baltic-German PowerLink project concept developed by Litgrid, Augstsprieguma tīkls, and 50Hertz includes a 2 GW, approximately 600 kilometres long hybrid offshore connection, with the connection point in the Baltic States planned to be on the border between Lithuania and Latvia. The exact location is to be determined after technical studies.
Note.
- The interconnectors may be long, but they are not longer than anything built successfully before in European waters.
- The UK and the Island of Ireland are well-linked.
- There would appear to be no need for challenging projects like the Morocco-UK Power Project
I suspect that Germany will get the energy it needs and the British Isles will get a nice little earner.
If Europe is generating large amounts of wind and solar energy with its variable output it will need lots of energy storage.
What Countries Have The Terrain For Pumped Storage Hydro In Europe?
I asked Google AI and received this answer.
Key countries with ideal, high-elevation terrain and significant existing or planned capacity include:
Alpine Region (The Heart of European Pumped Storage):
Switzerland: Extremely high capacity due to steep, mountainous landscapes and significant water sources, hosting the world’s oldest working pumped storage plant.
Austria: Heavily mountainous, it is a major player in PSH expansion and modernization.
France: Home to one of Europe’s largest, the Grand Maison hydroelectric power station.
Italy: Holds high capacity with numerous planned projects.
Germany: Strong existing infrastructure.
Southern Europe:
Spain: Features some of Europe’s largest plants (e.g., La Muela/Cortes-La Muela).
Portugal: Significant recent investment in large-scale projects like the Tâmega complex.
Other Potential Areas:
Norway: High potential due to its mountainous, water-rich terrain.
United Kingdom: High project volume currently under construction.
Balkans & Central Europe:
Countries like Bulgaria, Romania, and the Czech Republic have suitable terrain for further development.
These countries benefit from significant hydraulic head (steep drop) and natural or artificial reservoir potential, making them ideal for storing energy for peak consumption hours.
Note.
- As expected, the Alpine region is Top of the League.
- The UK is holding its own despite its small mountains.
- There is a lot of potential to be developed.
But then Electric Mountain in Snowdonia is certainly at the top table of pumped storage systems despite being built in the 1980s.
What Countries Have The Terrain For Hydrogen Storage In Europe?
I asked Google AI and received this answer.
Key European countries with suitable geological terrain—specifically salt caverns and depleted gas fields—for large-scale, underground hydrogen storage include Germany, the Netherlands, Denmark, the United Kingdom, and France. Other significant regions for storage potential include Spain, Hungary, and Austria, which are developing porous storage facilities.
Key Regions & Terrain Types:
Salt Caverns (North-Western Europe): Germany, the Netherlands, Denmark, France, and the UK have substantial salt deposits suitable for creating caverns, identified as cost-efficient for large-scale storage.
Depleted Gas Fields (Porous Rock): The Netherlands, Germany, and parts of Central/Southern Europe (Spain, Hungary) have significant capacity in existing porous storage, particularly in the North Sea region.
Specific Projects: Germany (Uniper’s Krummhörn project), Netherlands (HyStock), and France (HYPSTER at Etrez) are active, with Spain and Denmark emerging as major hydrogen hubs.
Capacity Potential: The Netherlands, for instance, holds massive potential (35-60 TWh) due to its offshore and onshore depleted fields.
Salt cavern projects, which offer high-deliverability storage, are heavily concentrated in the North-Western European industrial corridor.
I was lucky enough have a tour of ICI’s salt mine in Cheshire, when I worked there in the 1960s and I remember these facts from those days.
- There was enough salt in the ground under Cheshire to last several thousand years.
- Most salt was extracted from boreholes, for making chlorine using electrolysis and the Castner-Kellner process.
- Hydrogen was a by-product and much of it was mixed with coal gas to raise steam for the works.
The same technique used to make boreholes to extract the salt, is used to hollow caverns in the salt to store gases like hydrogen.
Once, when they were digging salt out of the salt mine at Winsford, a worker broke into an unmarked borehole and ICI nearly lost the mine because of the water rushing in.
Two stories stand out from the rescue of the mine.
- There was a need for dry clothes for all the workers, so ICI took a truck to Marks & Spencer in Northwich and emptied it of anything they might need. I was told the story enriched with plagues of locusts.
- A Ford Transit was found to have travelled a few thousand miles underground in axle deep salt slurry. Rather, than scrap it and buy another, it was offered back to Ford, who were delighted to swap it for a new one. I heard that Ford said, that the accelerated corrosion research would have taken many years, if done on the roads.
Always think out of the box.
Consultation On Offshore Wind Reform: Hydrogen Sector Calls For Hybrid Connection Concepts And Warns Of Compensation Risks
The title of this post, is the same as that of this article on the AquaVentus web site.
There is this statement on the home page.
Berlin, January 02 2026. In the context of the consultation launched by the Federal Ministry for Economic Affairs and Energy (BMWE) on the reform of the Wind Energy at Sea Act (WindSeeG), the hydrogen initiative AquaVentus is calling for clear legislative action to enable a cost-efficient and system-friendly development of offshore wind energy. At the heart of its position is the timely legal establishment of hybrid connection concepts, allowing offshore wind farms to be connected via both electricity cables and hydrogen pipelines.
Note.
- I’ve always felt that copying proven technologies from the offshore oil and gas industry is good practice.
- It may be easier to recycle infrastructure like pipelines, platforms and storage by creating the hydrogen offshore.
- In the UK, Centrica and SSE are already re-purposing natural gas storage for hydrogen.
It may feel safer to some for the hydrogen to be produced a distance offshore.
