H2DO Launches Offshore Wind-to-Hydrogen Study In Dutch North Sea
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Hydrogen of Dutch Origin (H2DO) and its partners have launched a feasibility and concept study for a 30–50 MW offshore green hydrogen project linked to offshore wind generation in the Dutch North Sea.
These two paragraphs add more details.
The project will examine the development of an offshore hydrogen production installation designed to convert electricity generated by offshore wind farms into hydrogen at sea and transport it to shore via pipeline infrastructure.
The study follows H2DO securing support in 2025 under the Dutch government’s Topsector Energie (TSE) programme, which funds energy innovation and green industrial development projects in the Netherlands.
I am sure this is a good way to develop hydrogen production.
I can envisage a time, when hydrogen is needed close to a windy coast, where a standard platform with a large wind turbine on top is erected in a suitable place and a pipe is run to the shore.
- The largest wind turbine is currently 26 MW.
- There are electrolysers, that can use sea water.
- I also suspect that a lot of gas technology can be repurposed to bring hydrogen ashore.
I certainly wish H2DO best of luck in their venture and I’ll be watching their progress.
JERA Nex BP, EnBW Submit Morven Offshore Wind Farm Application
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
A joint venture between JERA Nex BP and EnBW has submitted Section 36 consent applications for the Morven offshore wind farm to the Scottish government
These two paragraphs add a few details.
The developer secured the seabed rights for the Morven offshore wind farm as a single project in the ScotWind Leasing Round in 2022 and split it into two separate projects during the early development phase.
Located around 60 kilometres off the coast of Aberdeenshire at its closest point, the site is planned to house Morven North and Morven South, which would have a combined installed capacity of up to 3 GW and around 190 wind turbines in total.
Morven Offshore Wind Farm now has a comprehensive web site.
The web site says that the electricity will be brought ashore at Hawthorn Pit.
This Google Map shows the location of Hawthorn Pit.
Note.
- Hawthorn Pit is indicated by the red arrow.
- Sunderland is at the top of the map on the coast.
- Aura Power has already obtained planning permission for Hawthorn Pit solar farm, which will be up to 49.9 MW.
- Zenobe are developing a battery-energy-storage-system(BESS) 1.5 km to the South-East of the new Hawthorn Pit substation, which will have an output of 300 MW. Sloppily, there is no detail on capacity, but Google AI indicates, it is a 300 MW/600 MWh battery.
- Hawthorn Pit substation is also the expected to be the Southern end of Eastern Green Link 1, which will help to bring Scottish wind power to England, which will be a 2 GW undersea interconnector to Torness.
In Murphy Starts Work On £2.5bn Eastern Green Link 1, I detail the start of building of Eastern Green Link 1 and say it should be operational by 2029.
When Is The Morven Offshore Wind Farm Expected To Be Commissioned?
I asked Google AI the question above and received this answer.
The 2.9 GW Morven offshore wind farm is expected to be fully commissioned and operational between 2031 and 2035, with initial grid connections and power export potentially starting as early as 2030.
The timeline for full deployment of the Morven Offshore Wind Farm remains somewhat flexible as it depends on final planning approvals and connection offers from the National Energy System Operator (NESO).
The Cables For The Morven Offshore Wind Farm And Eastern Green Link 1
This map clipped from the Morven Offshore Wind Farm web site, shows the locations of Aberdeen, Hawthorn Pit and the Morven Offshore Wind Farm.
Note.
- The location of the Morven wind array was first mentioned in June 2020, as part of ScotWind by Crown Estate Scotland.
- The development of Eastern Green Link 1 was first mentioned in May 2021, by National Grid.
- Torness is to the East of Edinburgh.
- Eastern Green Link 1 connects Torness and Hawthorn Pit.
- the Morven wind array connects to England at Hawthorn Pit.
Over the last few years National Grid and other companies have been developing a technique called offshore hybrid assets, which I describe in What Are Offshore Hybrid Assets?.
An offshore hybrid asset typically connects two countries via a large offshore wind farm, which can then send electricity to both countries.
In a traditional design, there would need to be.
- A 2 GW cable between Torness and Hawthorn Pit.
- A 2.9 GW cable between Morven and Hawthorn Pit.
In the Offshore Hybrid Asset design, there would need to be.
- A 2 GW cable between Torness and Morven
- A 2.9 GW cable between Morven and Hawthorn Pit.
I suspect cable would be saved.
This map shows the position of each ScotWind Leasing wind farm.
Note.
- The numbers are Scotwind’s lease number in their documents.
- Morven is ScotWind lease number 1.
- Eastern Green Link 1 is one of four interconnectors down the East Coast of the UK.
- I have added up the ScotWind lease numbers 1-6 and they total 10.5 GW.
That would be a lot of power to capture just by converting the four Eastern Green Link interconnectors into offshore hybrid assets.
How Will Aquaventus Connect To Aberdeen?
This is RWE’s description of AquaVentus, which is sub-titled Hydrogen Production In The North Sea.
Hydrogen is considered the great hope of decarbonisation in all sectors that cannot be electrified, e.g. industrial manufacturing, aviation and shipping. Massive investments in the expansion of renewable energy are needed to enable carbon-neutral hydrogen production. After all, wind, solar and hydroelectric power form the basis of climate-friendly hydrogen.
In its quest for climate-friendly hydrogen production, the AquaVentus initiative has set its sights on one renewable energy generation technology: offshore wind. The initiative aims to use electricity from offshore wind farms to operate electrolysers also installed at sea on an industrial scale. Plans envisage setting up electrolysis units in the North Sea with a total capacity of 10 gigawatts, enough to produce 1 million metric tons of green hydrogen.
RWE have also put this AquaVentus video on their web site.
Note, that in the video AquaVentus connects Germany to Denmark, Norway, The Netherlands and Aberdeen and Humberside in the UK.
I asked Google AI, the question in the title of this section, and received this answer.
AquaVentus connects to Aberdeen through a strategic infrastructure partnership with Hydrogen Scotland. The two organizations are integrating offshore wind power, offshore electrolysis, and a shared cross-border pipeline to link Scottish renewable generation with European industrial markets.
The connection strategy relies on a multi-stage approach across the North Sea:
Offshore Production & Transmission: AquaVentus aims to produce green hydrogen directly offshore. It will be transported via a pan-European pipeline network—such as the planned 400 km AquaDuctus to link offshore hubs with both the UK and mainland Europe.
Scottish-German Export Corridor: Building on previous research like the Scot2Ger study, this pipeline corridor directly connects Scotland’s abundant offshore wind resources to European demand, establishing Aberdeen as a critical origin node.
Integrated Energy Backbone: The initiative champions hybrid connection concepts (combining both power cables and hydrogen pipelines). This allows for maximum flexibility when integrating Aberdeen’s local onshore hydrogen infrastructure with broader transnational energy grids.
I will now ask Google AI some supplementary questions about AquaVentus in UK waters.
“Will AquaVentus Produce Hydrogen In UK Waters?”
Google AI gave this reply.
Yes, AquaVentus plans to produce green hydrogen in UK waters. The German-led consortium has partnered with Hydrogen Scotland to harness Scotland’s offshore wind potential for large-scale, cross-border hydrogen production and export.
Key Details of the UK-German Initiative
Production Scale: The initiative aims to install 10 gigawatts (GW) of offshore electrolysis capacity in the North Sea by 2035, producing up to 1 million metric tonnes of green hydrogen annually.
The “Pipes and Wires” Model: Offshore wind parks will be equipped with hybrid connection concepts, providing the flexibility to either send electricity directly to the grid or convert it into hydrogen via offshore electrolysers.
Transportation: The produced hydrogen will be transported to land via a shared transnational subsea pipeline corridor, linking Scottish resources to Germany and mainland Europe.The partnership is specifically aimed at creating a North Sea hydrogen corridor to boost energy security and build the foundational European Hydrogen Backbone.
“Will AquaVentus Land Hydrogen In Scotland?”
Google AI gave this reply.
Yes, the German-led AquaVentus initiative plans to land green hydrogen in Scotland as part of a coordinated North Sea energy corridor.
The cross-border initiative involves the following components:
The Pipeline Connection: A key part of the plan is the AquaDuctus offshore subsea pipeline, designed to collect green hydrogen produced from central North Sea wind farms and land it on the coast.
Scottish Partnership: Hydrogen Scotland and AquaVentus have formalized a Memorandum of Understanding to combine Scotland’s massive offshore wind potential with German infrastructure and electrolysis expertise.
Export Ambitions: Scotland aims to produce up to 3.3 Mt of green hydrogen per year by 2045, heavily relying on pipelines and networks to export this to mainland European hubs like Germany.
Offshore Facilities: The broader initiative plans to install 10 GW of offshore electrolysis capacity in the North Sea to produce up to 1 million tonnes of hydrogen annually.
Note that Google AI has told me that a Megatonne of hydrogen is currently worth around £2.5-5 billion.
“Will AquaVentus Connect To Any Of The ScotWind Leasing Wind Farms?”
Google AI gave this reply.
Yes, AquaVentus plans to link Scottish offshore wind resources (including ScotWind farms) to mainland Europe. Through an agreement with Hydrogen Scotland, AquaVentus intends to utilize hybrid “pipes and wires” infrastructure to transmit power or convert it into green hydrogen for direct pipeline transport.
The partnership serves several strategic goals:
The “Pipes & Wires” Concept: Wind farms built under the ScotWind leasing round will have the flexibility to either route electricity to the UK grid or convert it into green hydrogen via offshore electrolysers.
Cross-Border Pipelines: The hydrogen generated by Scottish offshore wind is targeted to be fed into the planned AquaDuctus pipeline, which forms a transnational energy corridor connecting the UK to Germany and the rest of Europe.
Policy Integration: AquaVentus is actively advocating for legal reforms to accommodate these cross-border hybrid connections, allowing direct pipeline integration for future offshore parks.
I believe these ScotWind Leasing wind farms could be connected to AquaVentus.
- 1 – Morven – 2.9 GW – JERA Nex BP, EnBW
- 2 – Ossian – 2.6 GW – SSE Renewables
- 3 – Bellrock – 1.2 GW – Falck Renewables
- 4 – CampionWind – 2 GW – Scottish Power, Shell
- 5 – Muir Mhòr – 0.8 GW – Vattenfall
- 6 – Bowdun – – 1 GW – Thistle Wind Partners
Note.
- All companies are major energy companies.
- The wind farms are in a cluster to the South-East of Scotland.
- Wind farms 2-5 are floating, and 1 and 6 are fixed.
- There is a maximum power of 10.5 GW.
- These wind farms would not need to be shut down, when there was too much wind, if the excess electricity could be converted into hydrogen.
- The “Pipes & Wires” Concept would allow all energy generated to be transferred to shore, either as electricity or hydrogen.
Cables would need to be laid to perform the functions of the Eastern Green Links 1-4.
- 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
Eastern Green Link 5 is under development between Aberdeenshire and Lincolnshire.
“Is Anderby Creek An Important Node In The Electricity Grid?”
Google AI gave this reply.
Yes, Anderby Creek has become a highly important landfall location for the UK’s electricity grid, acting as a crucial connection point for high-capacity subsea cables bringing renewable energy from Scotland and offshore wind farms into England.
Its role in the national grid’s infrastructure centers on several major “superhighway” projects:
Eastern Green Link 5 (EGL 5): This £3bn National Grid project involves a 585km subsea High Voltage Direct Current (HVDC) cable carrying up to 2 GW of clean power (enough for two million homes) from Aberdeenshire, Scotland, to Anderby Creek.
Eastern Green Links 3 & 4 (EGL 3 / EGL 4): These are additional massive subsea cable projects that also plan to make landfall at Anderby Creek to transport Scottish wind energy down the UK coastline.
Offshore Wind Export Cables: Beyond long-distance transmission, the village already hosts export cables from local offshore wind developments like the Triton Knoll Wind Farm.
Because of the massive volume of power coming ashore, Anderby Creek serves as the starting point for significant onshore infrastructure. The cables transition underground at the beach and run roughly 8km inland to a proposed new converter station near Bilsby/Alford, where the power is converted and integrated into the broader Great Grid Upgrade.
“Will AquaVentus Have Access To The UK’s hydrogen Storage On Humberside?”
Google AI gave this reply.
Yes. Through a strategic partnership with Hydrogen Scotland, the AquaVentus initiative aims to establish cross-border offshore infrastructure that connects the central North Sea with existing and planned hydrogen networks across the UK, including those on Humberside.
The pipeline infrastructure associated with AquaVentus is envisioned to reach the UK just south of the massive hydrogen storage facilities located in East Yorkshire. While the German offshore pipeline (like AquaDuctus) is focused on landing green hydrogen into Germany, the broader AquaVentus framework is designed to integrate with British transmission networks and link to underground cavern storage in the UK.
On Humberside, major energy giants (including Centrica, Equinor, and SSE Thermal) are developing the integrated Humber Hydrogen transport and storage network. This system encompasses large-scale hydrogen storage at the Aldbrough Hydrogen Storage site and Rough Gas Storage. Because the AquaVentus UK branch connects to the Humber area’s onshore network, it positions the initiative to take advantage of these regional storage assets as a cornerstone for international trade and domestic energy resilience.
I think this is key as it gives AquaVentus access to very large hydrogen storage.
Conclusion
It almost looks to me, that National Grid and AquaVentus are combining their pipes and wires between the Southern North Sea and Aberdeen.
- Hydrogen offtake for Germany will be at Wilhelmshaven.
- Hydrogen offtake for England will be at Humberside.
- Hydrogen offtake for Scotland will be at Aberdeen.
- Electricity offtake for Germany will be at Wilhelmshaven.
- Electricity offtake for England will be at Anderby Creek.
- Electricity offtake for England will be at Hawthorn Pit.
- Electricity offtake for Scotland will be at Torness.
- Electricity offtake for Scotland will be at Aberdeen.
Note.
- There will probably be other connections to onshore locations and offshore wind farms.
- Hydrogen imports will be possible from Denmark, Norway and The Netherlands direct into AquaVentus.
TenneT, National Grid Ink Joint Development Agreement For LionLink Offshore Wind Interconnector
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Transmission system operators (TSOs) TenneT and National Grid Ventures (NGV) have signed a Joint Development Agreement (JDA) to advance LionLink, a hybrid interconnector linking the UK and the Netherlands via a future offshore wind farm in the Dutch North Sea.
These three paragraphs add more details.
The agreement sets out how the two partners will jointly develop LionLink towards a final investment decision (FID), including arrangements on procurement, governance, and planning, while also aiming to increase transparency on project costs ahead of construction.
LionLink is designed to integrate cross-border electricity interconnection with offshore wind by establishing a direct connection between the two countries through a grid link to the planned Nederwiek 3 offshore wind farm. According to the developers, this approach will maximise the use of offshore wind, provide additional system flexibility, and reduce the overall amount of required offshore infrastructure.
The LionLink project was launched in April 2023, when the Netherlands and the UK unveiled their plan to build the interconnector, a first-of-its-kind electricity link to connect offshore wind between the two countries via interconnections.
The same article also said these two paragraphs about the operation of the BritNed interconnector.
While the companies move forward with LionLink, their existing BritNed interconnector is marking 15 years of operation. Since entering service in 2011, the 1 GW subsea link has enabled nearly 93 TWh of electricity trading between Great Britain and the Netherlands.
Over the past five years, BritNed has exchanged enough electricity annually to power around 1.4 million households. The 260-kilometre interconnector remains a key part of both countries’ energy systems and has generated around EUR 1 billion in auction revenues on the Dutch side during its operational lifetime, TenneT said in a press release on 1 April.
It looks like BritNed has been a good investment for all stakeholders.
Note.
- LionLink will be a 2 GW interconnector.
- LionLink will land at Walberswick in Suffolk.
- LionLink has a web site.
- BritNed is a 1 GW interconnector.
- BritNed lands at the Isle of Grain in Kent.
- BritNed has a web site.
- NemoLink is an interconnector between Kent and Belgium.
- NeuConnect will be a 1.4 GW interconnector between the Isle of Grain and Wilhelmshaven, which will be operational by 2028.
- There are two actual and two proposed interconnectors between the UK and France.
The List of high-voltage transmission links in the United Kingdom in Wikipedia is growing.
The Wikipedia entry says this about the Rise of UK Interconnection.
The Department for Energy Security and Net Zero’s Digest of UK Energy Statistics reports that the UK was a net importer of electricity in 2024, with net imports of 33.4 TWh, up 40% from 2023.
Interconnectors allow the trade of electricity between countries with excess generation (for example, intermittent renewable) and those with high demand. Interconnectors play a key part in balancing variable renewable generation, for example the 1.4 GW North Sea Link allows the UK to export excess power to Norway during windy periods to conserve Norwegian hydro stocks, and import Norwegian hydro power on less windy days.
During the 2022 energy crisis, the UK exported record amounts of power to mainland Europe, helping to alleviate the effects of the Russian invasion of Ukraine on European security of supply.
As of 12 November 2024, Great Britain had nine operational international electricity interconnectors.
The UK is becoming an offshore energy substation on Europe’s North-West coast.
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.
‘Mobilising EUR 1 Trillion in Investments’ | North Sea Countries, Industry, TSOs to Ink Offshore Wind Pact
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Government officials from Belgium, Denmark, France, Germany, Ireland, Luxembourg, the Netherlands, Norway and the UK are set to sign a declaration confirming the ambition to build 300 GW of offshore wind in the North Seas by 2050, and an investment pact with the offshore wind industry and transmission system operators (TSOs) that is said to mobilise EUR 1 trillion in economic activity.
These three paragraphs add a lot of powerful detail.
Under the Offshore Wind Investment Pact for the North Seas, to be signed today (26 January) at the North Sea Summit in Hamburg, governments of the nine North Sea countries will commit to building 15 GW of offshore wind per year from 2031 to 2040.
The heads of state and energy ministers will also vow to de-risk offshore wind investments through a commitment to provide two-sided Contracts for Difference (CfDs) as the standard for offshore wind auction design. The pact also commits governments to remove any regulatory obstacles to power purchase agreements (PPAs), according to WindEurope, which will sign the pact on behalf of the industry.
On the industry’s side, the commitment is to drive down the costs of offshore wind by 30 per cent towards 2040, mobilise EUR 1 trillion of economic activity for Europe, create 91,000 additional jobs and invest EUR 9.5 billion in manufacturing, port infrastructure and vessels.
These two paragraphs say something about cost reductions.
The cost reduction of offshore wind is planned to be achieved through scale effects, lower costs of capital and further industrialisation supported by clarity and visibility on the project pipeline.
The transmission system operators (TSOs) will identify cost-effective cooperation projects in the North Sea, including 20 GW of promising cross-border projects by 2027 for deployment in the 2030s.
I hope there is a project management system, that can step into this frenzy, just as Artemis did in the 1970s with North Sea Oil and Gas.
The BBC has reported the story under a title of UK To Join Major Wind Farm Project With Nine European Countries.
this is the sub-title.
The UK is set to back a vast new fleet of offshore wind projects in the North Sea alongside nine other European countries including Norway, Germany and the Netherlands.
These six paragraphs add more detail.
The government says the deal will strengthen energy security by offering an escape from what it calls the “fossil fuel rollercoaster”.
For the first time, some of the new wind farms will be linked to multiple countries through undersea cables known as interconnectors, which supporters say should lower prices across the region.
But it could prove controversial as wind farm operators would be able to shop around between countries to sell power to the highest bidder – potentially driving up electricity prices when supply is tight.
Energy Secretary Ed Miliband will sign a declaration on Monday at a meeting on the future of the North Sea in the German city of Hamburg, committing to complete the scheme by 2050.
Jane Cooper, deputy CEO of industry body RenewableUK, said the deal would “drive down costs for billpayers” as well as increasing “the energy security of the UK and the whole of the North Sea region significantly”.
But Claire Countinho, shadow energy secretary, warned “we cannot escape the fact that the rush to build wind farms at breakneck speed is pushing up everybody’s energy bills.”
Claire Coutinho, as an outsider at present and a member of a party out of Government had to say something negative, but her negotiations when she was UK Energy Minister with her German opposite number, which I wrote about in UK And Germany Boost Offshore Renewables Ties, seem very much a precursor to today’s agreement.
First Monopile In At ‘Most Ecological Offshore Wind Farm Yet’
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Van Oord, using its installation vessel Boreas, installed the first monopile at the Ecowende offshore wind farm on 3 December. The project, a joint venture between Shell, Eneco and Chubu Electric Power, is being built off the coast of the Netherlands and is said to become the most ecological offshore wind farm to date.
These four paragraphs add more details.
The offshore wind farm, located approximately 53 kilometres off the Dutch coast near IJmuiden, will have 52 monopile foundations produced by Sif and Smulders supporting 52 Vestas V236-15.0 MW wind turbines.
The offshore wind farm is dubbed “the most ecological to date” since it incorporates several technologies and methodologies that are nature-inclusive, including monopiles coming in two diameters, 8.8 metres and 9.3 metres, to support varying turbine tower heights, as research indicates that higher turbine tip heights may allow birds to fly more safely between the structures, reducing collision risks.
Some of the wind turbines will feature red blades as part of a trial to assess whether increased visibility reduces bird collisions.
Offshore construction on Ecowende (Hollandse Kust West Site VI) offshore wind farm started in September with the installation of eco-friendly scour protection.
Note.
- It looks like its a 780 MW wind farm.
- They’re certainly looking after the birds.
- Scour protection is mainly to protect the wind farm, but at least it’s eco-friendly.
But then the Dutch must know a bit about building windmills, that last a long time.
Centrica Really Can’t Lose At Sizewell
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Centrica’s £1.3 billion investment in Sizewell C guarantees substantial returns, even with cost overruns.
These two-and-a-half paragraphs explain the funding.
Now we know what Ed Miliband means by his “golden age of nuclear” — golden for the companies putting their money into Sizewell C. Yes, reactor projects have a habit of blowing up private investors. But maybe not this one. It looks more like an exercise in transferring risk to consumers and the taxpayer.
Sure, nobody builds a £38 billion nuke on a Suffolk flood plain without a frisson of danger. But the energy secretary and his Treasury chums have done their bit to make things as safe as possible for the companies putting in equity alongside the government’s 44.9 per cent stake: Canada’s La Caisse with 20 per cent, British Gas-owner Centrica (15 per cent), France’s EDF (12.5 per cent) and Amber Infrastructure (7.6 per cent).
For starters, nearly all the debt for the 3.2 gigawatt plant, three-quarters funded by loans, is coming from the state-backed National Wealth Fund. It’s bunging in up to £36.6 billion, with £5 billion more guaranteed by a French export credit agency.
It looks to me that between them the British and French governments are providing £41.5 billion of loans to build the £38 billion nuke.
These are my thoughts.
Hydrogen And Sizewell C
This page on the Sizewell C web site is entitled Hydrogen And Sizewell C.
Under a heading of Hydrogen Buses, this is said.
At Sizewell C, we are exploring how we can produce and use hydrogen in several ways. We are working with Wrightbus on a pilot scheme which, if successful, could see thousands of workers transported to and from site on hydrogen double decker buses. You can read more about the pilot scheme in our press release
Firstly, it could help lower emissions during construction of the power station. Secondly, once Sizewell C is operational, we hope to use some of the heat it generates (alongside electricity) to make hydrogen more efficiently.
This would appear to be a more general statement about hydrogen and that the following is planned.
- Hydrogen-powered buses will be used to bring workers to the site. A press release on the Sizewell C web site, talks about up to 150 buses. That would probably be enough buses for all of Suffolk.
- Hydrogen-powered construction equipment will be used in the building of the power station.
- It also talks about using the excess heat from the power station to make hydrogen more efficiently. I talk about this process in Westinghouse And Bloom Energy To Team Up For Pink Hydrogen.
This is a substantial investment in hydrogen.
Centrica And Electricity From Sizewell C
The article in The Times, also says this.
Even so, there’s a fair bit of protection for the likes of Centrica, which has also agreed a 20-year offtake deal for its share of Sizewell’s electricity. The price of that is not yet known.
Nothing is said in the article about the size of Centrica’s electricity offtake.
- If they get 15 % of Sizewell C, that would by 480 MW.
- If they get 15 % of Sizewell B + C, that would by 660 MW.
If they use their share to generate hydrogen, Suffolk would have a massive hydrogen hub.
To power the buses and construction of Sizewell C, Sizewell B could be used to provide electricity to create the hydrogen.
How Would The Hydrogen Be Produced?
Centrica, along with other companies, who include Hyundai and Kia, are backers of a company in Hull called HiiROC, who use a process called Thermal Plasma Electrolysis to generate hydrogen.
On their web site, they have this sub-heading.
A Transformational New Process For Affordable Clean Hydrogen
The web site also describes the process as scalable from small modular units up to industrial scale. It also says this about the costs of the system: As cheap as SMR without needing CCUS; a fraction of the energy/cost of water electrolysis.
If HiiROC have achieved their objective of scalability, then Centrica could grow their electrolyser to meet demand.
How Would The Hydrogen Be Distributed?
Consider.
- Currently, the Sizewell site has both road and rail access.
- I can still see in my mind from the 1960s, ICI’s specialist articulated Foden trucks lined up in the yard at Runcorn, taking on their cargoes of hydrogen for delivery all over the country.
- As that factory is still producing hydrogen and I can’t remember any accidents in the last sixty years, I am fairly sure that a range of suitable hydrogen trucks could be developed to deliver hydrogen by road.
- The road network to the Siewell site is being updated to ensure smooth delivery of workers and materials.
- The rail access to the Sizewell site is also being improved, for the delivery of bulk materials.
I believe there will be no problems delivering hydrogen from the Sizewell site.
I also believe that there could be scope for a special-purpose self-propelled hydrogen tanker train, which could both distribute and supply the hydrogen to the vehicles, locomotives and equipment that will be using it.
Where Will The Hydrogen Be Used?
I have lived a large part of my life in Suffolk and know the county well.
In my childhood, there was quite a lot of heavy industry, but now that has all gone and employment is based on agriculture, the Port of Felixstowe and service industries.
I can see hydrogen being used in the following industries.
Transport
Buses and heavy trucks would be powered by hydrogen.
The ports in the East of England support a large number of heavy trucks.
Large Construction Projects
Sizewell C is not the only large construction project in the East of England, that is aiming to use low-carbon construction involving hydrogen. In Gallagher Group Host Hydrogen Fuel Trial At Hermitage Quarry, I talked about a hydrogen fuel trial for the Lower Thames Crossing, that involved JCB and Ryse Hydrogen.
Hydrogen for the Lower Thames Crossing could be delivered from Sizewell by truck, down the A12.
Rail
We may not ever see hydrogen-powered passenger trains in this country, but I do believe that we could see hydrogen-powered freight locomotives.
Consider.
- The latest electro-diesel Class 99 locomotives from Stadler have a Cummins diesel engine.
- The diesel engine is used, when there is no electrification.
- Cummins have developed the technology, that allows them to convert their latest diesel engines to hydrogen or natural gas power, by changing the cylinder head and the fuel system.
- Access to the Port of Felixstowe and London Gateway needs a locomotive with a self-powered capability for the last few miles of the route.
A Class 99 locomotive converted to hydrogen would be able to run with out emitting any carbon dioxide from Felixstowe or London Gateway to Glasgow or Edinburgh.
Ports
Ports have three main uses for hydrogen.
- To power ground-handing equipment, to create a pollution-free atmosphere for port workers.
- To fuel ships of all sizes from the humblest work-boat to the largest container ships.
- There may need to be fuel for hydrogen-powered rail locomotives in the future.
There are seven ports with excellent road and/or rail connections to the Sizewell site; Felixstowe, Great Yarmouth, Harwich, Ipswich, London Gateway, Lowestoft and Tilbury.
The proposed Freeport East is also developing their own green hydrogen hub, which is described on this page on the Freeport East web site.
Airports
Airports have two main uses for hydrogen.
- To power ground-handing equipment, to create a pollution-free atmosphere for airport workers.
- In the future, there is likely to be hydrogen-powered aircraft.
There are three airports with excellent road and/or rail connections to the Sizewell site; Norwich, Southend and Stansted.
Agriculture And The Rural Economy
Agriculture and the rural economy would be difficult to decarbonise.
Consider.
- Currently, most farms would use diesel power for tractors and agricultural equipment, which is delivered by truck.
- Many rural properties are heated by propane or fuel oil, which is delivered by truck.
- Some high-energy rural businesses like blacksmiths rely on propane, which is delivered by truck.
- Electrification could be possible for some applications, but ploughing the heavy land of Suffolk, with the added weight of a battery on the tractor, would probably be a mathematical impossibility.
- JCB are developing hydrogen-powered construction equipment and already make tractors.
- Hydrogen could be delivered by truck to farms and rural properties.
- Many boilers can be converted from propoane to run on hydrogen.
I feel, that hydrogen could be the ideal fuel to decarbonise agriculture and the rural economy.
I cover this application in detail in Developing A Rural Hydrogen Network.
Exports
Consider.
- Sizewell B and Sizewell C nuclear powerstations have a combined output of 4.4 GW.
- A rough calculation shows that there is a total of 7.2 GW of wind farms planned off the Suffolk coast.
- The East Anglian Array wind farm alone is said in Wikipedia to be planned to expand to 7.2 GW.
- The Sizewell site has a high capacity connection to the National Grid.
Nuclear plus wind should keep the lights on in the East of England.
Any excess electricity could be converted into hydrogen.
This Google Map shows the location of Sizewell B in relation to Belgium, Germany and The Netherlands.
The Sizewell site is indicated by the red arrow.
The offshore oil and gas industry has used technology like single buoy moorings and coastal tankers to collect offshore natural gas for decades.
I don’t see why coastal hydrogen tankers couldn’t export excess hydrogen to places around the North Sea, who need the fuel.
It should be born in mind, that Centrica have a good reputation in doing natural gas trading. This expertise would surely be useful in hydrogen trading.
Conclusion
I believe that a hydrogen hub developed at Sizewell makes sense and I also believe that Centrica have the skills and technology to make it work.
Ørsted Pulls Plug On 2.4 GW Hornsea 4 Offshore Wind Project In UK
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ørsted has discontinued the development of the UK’s Hornsea 4 offshore wind farm in its current form. The developer said the 2.4 GW project has faced rising supply chain costs, higher interest rates, and increased construction and delivery risks since the Contract for Difference (CfD) award in Allocation Round 6 (AR6) in September 2024.
This introductory paragraph adds more detail.
In combination, these developments have increased the execution risk and deteriorated the value creation of the project, which led to Ørsted stopping further spending on the project at this time and terminating the project’s supply chain contracts, according to the Danish company. This means that the firm will not deliver Hornsea 4 under the CfD awarded in AR6.
Consider.
- Hornsea 4 will be connected to the grid at a new Wanless Beck substation, which will also include a battery and solar farm, which will be South West of the current Creyke Beck substation. Are Ørsted frightened of opposition from the Nimbies to their plans?
- I also wonder if political uncertainty in the UK, and the possibility of a Reform UK government, led by Nigel Farage is worrying companies like Ørsted.
So will factors like these prompt companies like Ørsted to move investment to countries, where they welcome wind turbines like Denmark, Germany and The Netherlands.
Could Ørsted Be Looking At An Alternative?
This is a map of wind farms in the North Sea in the Dogger Bank and Hornsea wind farms, that I clipped from Wikipedia..
These are the Dogger Bank and Hornsea wind farms and their developers and size
- 37 – Dogger Bank A – SSE Renewables/Equinor – 1,235 MW
- 39 – Dogger Bank B – SSE Renewables/Equinor – 1,235 MW
- 38 – Dogger Bank C – SSE Renewables/Equinor – 1,218 MW
- 40 – Sofia – RWE – 1,400 MW
- 1 – Hornsea 1 – Ørsted/Global Infrstructure Partners – 1,218 MW
- 32 – Hornsea 2 – Ørsted/Global Infrstructure Partners – 1,386 MW
- 47 – Hornsea 3 – Ørsted – 2,852 MW
- 51 – Hornsea 4 – Ørsted – 2,400 MW
Note.
- That is a total of 12, 944 MW, which is probably enough electricity to power all of England and a large part of Wales.
- Wikipedia’s List of offshore wind farms in the United Kingdom, also lists a 3,000 MW wind farm, that is being developed by German company ; RWE called Dogger Bank South,
- The Dogger Bank South wind farm is not shown on the map, but would surely be South of wind farms 37 to 40 and East of 51.
- The Dogger Bank South wind farm will raise the total of electricity in the Dogger Bank and Hornsea wind farms to just short of 16 GW.
Connecting 16 GW of new electricity into the grid, carrying it away to where it is needed and backing it up, so that power is provided, when the wind doesn’t blow, will not be a nightmare, it will be impossible.
An alternative plan is needed!
AquaVentus To The Rescue!
AquaVentus is a German plan to bring 10 GW of green hydrogen to the German mainland from the North Sea, so they can decarbonise German industry and retire their coal-fired power stations.
- I introduce AquaVentus in AquaVentus, which I suggest you read.
- AquaVentus is being developed by RWE.
- AquaVentus connects to a German hydrogen network called H2ercules to actually distribute the hydrogen.
This video shows the structure of AquaVentus.
I clipped this map from the video.
Note.
- The thick white line running North-West/South-East is the spine of AquaVentus, that will deliver hydrogen to Germany.
- There is a link to Esbjerg in Denmark, that is marked DK.
- There appears to be an undeveloped link to Norway, which goes North,
- There appears to be an undeveloped link to Peterhead in Scotland, that is marked UK.
- There appears to be a link to just North of the Humber in England, that is marked UK.
- Just North of the Humber are the two massive gas storage sites of Aldbrough owned by SSE and Brough owned by Centrica.
- Aldbrough and Rough gas storage sites are being converted into two of the largest hydrogen storage sites in the world!
- There appear to be small ships sailing up and down the East Coast of the UK. Are these small coastal tankers, that are distributing the hydrogen to where it is needed?
When it is completed, AquaVentus will be a very comprehensive hydrogen network.
I believe that offshore electrolysers could be built in the area of the Hornsea 4 and Dogger Bank South wind farms and the hydrogen generated would be taken by AquaVentus to either Germany or the UK.
- Both countries get the hydrogen they need.
- Excess hydrogen would be stored in Aldbrough and Rough.
- British Steel gets decarbonised.
- A 1.8 GW hydrogen-fired powerstation at Keadby gets the hydrogen it needs to backup the wind farms.
Germany and the UK get security in the supply of hydrogen.
These may be my best guesses, but they are based on published plans.
From Doncaster To Cleethorpes
These pictures were taken on my journey between Doncaster and Cleethorpes.
The area is best summed up as flat and decorated with these features.
- A few hedges.
- Some trees and some woodland.
- dozens of wind turbines.
- Lots of pylons carrying electricity.
- Scunthorpe steelworks
- A few stations and railway sidings.
- A couple of waterways.
- Estates of new housing as you approach Grimsby.
When I returned there was more of the same on the other side of the tracks.
With the addition of all the power stations at Keadby and a couple of wind farms.
These are my thoughts on how this landscape will look at some time after 2030.
More Onshore Wind Farms
There will be a lot more wind farms lining the Doncaster and Cleethorpes railway.
The government has said it might pay for turbines and transmission lines to spoil views.
I feel they will have to, to meet their net-zero targets.
There Will Be Massive Hydrogen Storage On The Other Side Of The Humber
SSE are developing Albrough and Centrica are developing Rough into two of the largest hydrogen stores in the world.
The wind farms of the North Sea will provide them with hydrogen.
More Housing
If the government has its wish there will be a lot more new housing.
And as the newer houses show in my pictures, many of them will have solar panels.
More Power Stations At Keadby
Consider.
- The main purpose of the power stations at Keadby will be to provide backup to the wind and solar power in the area and far out to sea.
- The power stations will use hydrogen stored at Albrough and Rough.
- Some of the gas-fired power stations at Keadby will be fitted with carbon capture.
- One hydrogen-fired power station is already being planned.
The power stations at Keadby will probably be capable of supplying several GW of zero-carbon energy.
There Will Be Energy-Hungry Industries Along The South Bank Of The Humber
Just as in the Victorian era, coal attracted steel-making, chemicals and refining to the area, a South Humberside with large amounts of energy will attract heavy industry again.
Already, Siemens have built a train factory at Goole.
There Will Also Be Large Greenhouses In Lincolnshire
Greenhouses are a wonderful green way of absorbing waste heat and carbon dioxide.
Where Have I Seen This Blend Of Offshore Energy, Hydrogen, Heavy Industry And Agriculture Before?
After I visited Eemshaven in the Northern Netherlands, I wrote The Dutch Plan For Hydrogen.
We are not doing something similar, but something much bigger, based on the hydrogen stores at Aldbrough and Brough, the massive offshore wind farms and Lincolnshire’s traditional heavy industry and agriculture.
The Railway Between Doncaster and Cleethorpes Will Be Developed
Just as the Dutch have developed the railways between Groningen and Eemshaven.
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.
