The Netherlands Chooses Site For World’s Largest Offshore Wind-to-Hydrogen Project
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Dutch government has designated an area for what will become the world’s largest offshore hydrogen production project. That area is Ten noorden van de Waddeneilanden (the North of the Wadden Islands), identified earlier for offshore wind development and deemed most suitable for providing 500 MW of electrolysis capacity and for the transport of hydrogen to land.
This Google Map shows the Wadden Islands.
Note.
- Groningen is in the South-East corner of the map.
- I wrote about Eemshaven, which is to the North-East of Groningen in The Train Station At The Northern End Of The Netherlands.
- The Wadden or Frisian Islands are along the coast.
The Wadden Islands of the Netherlands, Germany and Denmark are a World Heritage Site.
In Can The UK Have A Capacity To Create Five GW Of Green Hydrogen?, I said the following.
Ryze Hydrogen are building the Herne Bay electrolyser.
- It will consume 23 MW of solar and wind power.
- It will produce ten tonnes of hydrogen per day.
The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.
If the Dutch build a 500 MW electrolyser it will produce 217 tonnes of hydrogen per day.
The Dutch Plan For Hydrogen
This 500 MW electrolyser fits well with the The Dutch Plan For Hydrogen.
First-Of-Its-Kind Electriq Powder Manufacturing Plant To Be Built In Amsterdam
The title of this post, is the same as that of this article on Hydrogen Fuel News.
This is the sub-heading.
The powder plant can provide a safe end-to-end hydrogen solution.
The home page of their web site has this bold statement.
Meet the Safe & Practical Hydrogen Powder
Underneath is this explanation.
Electriq is a hydrogen carrier that acts like coffee powder for a coffee machine – simplifying storage, transport, and use of hydrogen in off-grid applications and long-term storage.
Similar processes have been proposed for hydrogen in the past, but no-one has compared them to coffee before.
This Technology page gives a lot more details.
These two paragraphs outline the chemistry used.
Electriq’s Fuel and Release technologies turn hydrogen into a coffee-like powder form, then back into electricity through a proprietary catalyst and release system.
Our hydrogenation process reacts hydrogen gas with KBO2 to produce a powdery coffee-like compound (KBH4), ready for easy storage and transportation. Our dehydrogenation process releases the hydrogen – and KBO2 as a by-product – thus forming a full cycle.
The Electriq Release system uses a proprietary catalyst to release hydrogen from the Electriq Fuel, after mixing it with water. The dehydrogenation (release) process provides fuel-cell grade hydrogen and zero-emissions electricity.
Note.
- KBO2 is a chemical compound formed of one potassium, one boron and two oxygen atoms.
- KBH4 is a chemical compound formed of one potassium, one boron and four hydrogen atoms.
- As is with often the case with these processes, It appears that there may be a clever catalyst doing some hard work.
The Technology page finishes with a comparison with other methods of transporting hydrogen.
This Press & Insights page has more information on the company and some interesting videos.
It would certainly be something new, if you filled up your electric bike with a canister of dry powder.
But they have a video of that!
Belgians To Start Building World’s First Artificial Energy Island Next Year (VIDEO)
The title of this post, is the same as that, of this article on offshoreWIND.biz.
This is the sub-heading.
Belgian offshore construction companies Jan De Nul and DEME, through their consortium TM EDISON, have won the tender for the construction of the Princess Elisabeth Island in their home country and the first artificial energy island in the world.
And this first paragraph outlines the project.
The artificial island, which will be built some 45 kilometres off the Belgian coast and will occupy an area of approximately five hectares above the waterline, will serve as the link between the offshore wind farms in the country’s second, 3.5 GW Princess Elisabeth offshore wind zone and its onshore high-voltage grid.
Initial plans don’t seem to be putting any wind turbines or solar panels on the island.
The most impressive part of the article is the video, which shows how the island will be constructed.
To some people of my age, the construction of the island will seem familiar, as the island will be built in a similar way to the Mulberry harbours of World War II.
A few years ago, I went inside some of the giant Pheonix caissons in The Netherlands, where they were initially used to plug the dykes after the North Sea Flood of 1953. They are now a museum of the floods called the Watersnoodmuseum.
Engineering is repeating itself.
Dutch Take Aim At Lower Green Hydrogen Costs By Combining Offshore Wind And Floating Solar
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
A consortium of Dutch companies has launched a government-backed project to explore the synergies between offshore wind, offshore solar and hydrogen production at sea for improved sustainability of North Sea renewable energy projects.
T thought about calling this post, The Dutch Go For The Full Monty, but there is no mention of wave or tidal power.
These two paragraphs outline the project.
The four-year project, dubbed Solar Enhanced North Sea Energy Hub (SENSE-HUB), is expected to accelerate the rollout of offshore solar into offshore renewable energy systems.
Let by TNO, short for Netherlands Organization for Applied Scientific Research, the project will address the integration of various energy system modules for the Dutch North Sea by understanding and removing the implementation barriers for future SENSE-HUBs from a technical, economical, ecological, legal and societal perspective.
I wouldn’t be surprised to see more integrated systems like this in the waters around our coasts.
I also believe that the ultimate offshore energy production system will also use wave and tidal power to generate electricity and have inbuilt energy storage.

EuroLink, Nautilus And Sea Link
EuroLink, Nautilus and Sea Link are three proposed interconnectors being developed by National Grid Ventures.
EuroLink
EuroLink has a web site, where this is said.
To support the UK’s growing energy needs, National Grid Ventures (NGV) is bringing forward proposals for a Multi-Purpose Interconnector (MPI) called EuroLink, which will deliver a new electricity link between Great Britain to the Netherlands.
EuroLink could supply up to 1.8 gigawatts (GW) of electricity, which will be enough to power approximately 1.8 million homes, as well as contribute to our national energy security and support the UK’s climate and energy goals. We’re holding a non-statutory public consultation to inform you about our EuroLink proposals, gather your feedback to help refine our plans and respond to your questions.
Note, that EuroLink is a Multi-Purpose Interconnector (MPI) and they are described on this page of the National Grid website.
In EuroLink’s case, this means it is basically an interconnector between the UK and The Netherlands, that also connects wind farms on the route to the shore.
- Coastal communities get less disruption, as the number of connecting cables coming ashore is reduced.
- Less space is needed onshore for substations.
- Electricity from the wind farms can be directed to where it is needed or can be stored.
As an Electrical and Control Engineer, I like the MPI approach.
The technology to implement the MPI approach is very much tried and tested.
There are many references to EuroLink terminating at Friston.
Nautilus
Nautilus has a web site, where this is said.
Nautilus could connect up to 1.4 gigawatts (GW) of offshore wind to each country through subsea electricity whilst connecting to offshore wind farm/s at sea. By combining offshore wind generation with interconnector capacity between the UK and Belgium, Nautilus would significantly reduce the amount of infrastructure and disruption required both onshore and offshore.
With this new technology, we hope to reduce the impact of infrastructure on local communities and the environment, as well as support the government’s net zero and energy security targets. We are already working closely with other developers in the area to coordinate activities and minimise impact on local communities. We believe that through improved coordination, the UK government can achieve and support the co-existence of renewable energy with coastal communities.
Nautilus is another MPI.
This is said on the web site.
Last year, National Grid Ventures ran a non-statutory consultation for Nautilus, which proposed a connection at Friston.
NGV holds a connection agreement on the Isle of Grain in Kent as part of its development portfolio and we are currently investigating if this could be a potential location for Nautilus. Until this is confirmed to be technically feasible, Nautilus will be included as part of our coordination work in East Suffolk.
So it looks like, Nautilus could connect to the UK grid at Friston or the Isle of Grain.
Sea Link
Sea Link has a web site, and is a proposed interconnector across the Thames Estuary between Suffolk and Kent.
This is said on the web site about the need for and design of Sea Link.
The UK electricity industry is evolving at pace to help lead the way in meeting the climate challenge, whilst also creating a secure energy supply based on renewable and low carbon technologies.
The demands on the electricity network are set to grow as other sectors of the economy diversify their energy consumption from using fossil fuels towards cleaner forms, the move towards electric vehicles being just one example.
Where we’re getting our power from is changing and we need to change too. The new sources of renewable and low-carbon energy are located along the coastline. We need to reinforce existing transmission network and build new electricity infrastructure in these areas in order to transport the power to where it’s needed. This is the case along the whole of the East Coast including Suffolk and Kent.
To allow this increase in energy generation, we need to reinforce the electricity transmission system. Sea Link helps to reinforce the electricity network across Suffolk and Kent.
Our proposals include building an offshore high voltage direct current (HVDC) link between Suffolk and Kent with onshore converter stations and connections back to the national electricity transmission system.
On the web site, in answer to a question of What Is Sea Link?, this is said.
Sea Link is an essential upgrade to Britain’s electricity network in East Anglia and Kent using subsea and underground cable. The proposal includes approximately 130km of subsea cables between Sizewell area in East Suffolk and Richborough in Kent. At landfall, the cables would go underground for up to 5 km to a converter station (one at each end). The converter station converts direct current used for the subsea section to alternating current, which our homes and businesses use. A connection is then made to the existing transmission network. In Suffolk, via the proposed Friston substation; in Kent via a direct connection to the overhead line between Richborough and Canterbury.
Note, that from Kent electricity can also be exported to the Continent.
All Cables Lead To Friston In Suffolk
It looks like EuroLink, Nautilus and Sea Link could all be connected to a new substation at Friston.
But these will not be the only cables to pass close to the village.
This Google Map shows the village.
Running South-West to North-East across the map can be seen the dual line of electricity pylons, that connect the nuclear power stations at Sizewell to the UK electricity grid.
Has Friston been chosen for the substation, so that, the various interconnectors can be connected to the power lines, that connect the Sizewell site to the UK electricity grid.
This would enable EuroLink, Nautilus and/or Sea Link to stand in for the Sizewell nuclear stations, if they are shut down for any reason?
It does appear from reports on the Internet that the Friston substation is not welcome.
Exploring Opportunities For Coordination
The title of this section is a heading in the EuroLink web site, where this is said.
In response to stakeholder feedback, NGV’s Eurolink and Nautilus projects and NGET’s Sea Link project are exploring potential opportunities to coordinate. Coordination could range from co-location of infrastructure from different projects on the same site, to coordinating construction activities to reduce potential impacts on local communities and the environment.
That sounds very sensible.
Dogger Bank – The Joke That Is Growing Up To Be A Wind Powerhouse
The Wikipedia entry for the Dogger Bank, describes it like this.
Dogger Bank is a large sandbank in a shallow area of the North Sea about 100 kilometres (62 mi) off the east coast of England.
But many of my generation remember it from its use in the Shipping Forecast and as a joke place like the Balls Pond Road, Knotty Ash and East Cheam, in radio and TV comedy from the 1950s and 1960s.
But now it is being turned into one of the largest wind powerhouses!
According to Wikipedia’s list of the UK’s offshore wind farms, these wind farms are being developed on the Dogger Bank.
- Sofia Offshore Wind Farm – 1400 MW – Under Construction – Commissioning in 2023/26 – £39.65/MWh – RWE
- Dogger Bank A – 1235 MW – Under Construction – Commissioning in 2023/24 – £39.65/MWh – SSE/Equinor
- Dogger Bank B – 1235 MW – Pre-Construction – Commissioning in 2024/25 – £41.61/MWh – SSE/Equinor
- Dogger Bank C – 1218 MW – Pre-Construction – Commissioning in 2024/25 – £41.61/MWh – SSE/Equinor
- Dogger Bank D – 1320 MW – Early Planning – SSE/Equinor
- Dogger Bank South – 3000 MW – Early Planning – RWE
Note.
- These total up to 9408 MW.
- The Dogger Bank wind farms have their own web site.
- The Sofia offshore wind farm has its own web site.
- The Dogger Bank South wind farms have their own web site.
- Dogger Bank A and Dogger Bank B will connect to the National Grid at Creyke Beck to the North of Hull.
- Sofia and Dogger Bank C will connect to the National Grid at Lazenby on Teesside.
But this is only the start on the British section of the Dogger Bank.
This map, which comes courtesy of Energy Network Magazine and 4C Offshore is entitled 2001 UK Offshore Windfarm Map shows all UK offshore wind farms and their status. It looks to my naive mind, that there could be space for more wind farms to the North and West of the cluster of Digger Bank wind farms.
The North Sea Wind Power Hub
The UK doesn’t have full territorial rights to the Dogger Bank we share the bank with the Danes, Dutch and Germans.
In the Wikipedia entry for the Dogger Bank wind farm, this is said about the North Sea Wind Power Hub.
Dutch, German, and Danish electrical grid operators are cooperating in a project to build a North Sea Wind Power Hub complex on one or more artificial islands to be constructed on Dogger Bank as part of a European system for sustainable electricity. The power hub would interconnect the three national power grids with each other and with the Dogger Bank Wind Farm.
A study commissioned by Dutch electrical grid operator TenneT reported in February 2017 that as much as 110 gigawatts of wind energy generating capacity could ultimately be developed at the Dogger Bank location.
Note.
- 110 GW shared equally would be 27.5 GW.
- As we already have 9.4 GW of wind power, under construction or in planning around the Dogger Bank, could we find space for the other 18.1 GW?
- I suspect we could squeeze it in.
If we can and the Danes, Dutch and Germans can generate their share, the four countries would each have a 27.5 GW wind farm.
What would put the icing on the cake, would be if there could be a massive battery on the Dogger Bank. It wouldn’t be possible now and many would consider it a joke. But who knows what the capacity of an underwater battery based on concrete, steel, seawater and masses of ingenuity will be in a few years time.
Where Does Norway Fit In To The North Sea Wind Power Hub?
It could be argued that Norway could also connect to the North Sea Wind Power Hub.
- 110 GW shared equally would be 22 GW.
- Norway can build massive pumped storage hydroelectric power stations close to the landfall of an interconnector to the North Sea Wind Power Hub.
- the British, Danes, Dutch and Germans can’t do that, as they don’t have any handy mountains.
- Norway is a richer country the others involved in the project.
I can see Norway signing up to the North Sea Wind Power Hub.
The North Sea Link
The Wikipedia entry for the North Sea Link, introduces it like this.
The North Sea Link is a 1,400 MW high-voltage direct current submarine power cable between Norway and the United Kingdom.
At 720 km (450 mi) it is the longest subsea interconnector in the world. The cable became operational on 1 October 2021.
It runs between Kvilldal in Norway and Blyth in Northumberland.
I wouldn’t be surprised to see that the North Sea Link is modified, so that it has a connection to the North Sea Wind Power Hub.
First-Ever Subsidy-Free Offshore Wind Farm Halfway Done
The title of this post, is the same as that of this article on offshoreWIND.biz.
These three paragraphs, outline the project.
Cadeler’s wind turbine installation vessel Wind Osprey has installed the 70th Siemens Gamesa 11 MW wind turbine at the 1.5 GW Hollandse Kust Zuid offshore wind farm in the Dutch North Sea.
The installation of the 70th turbine marks the halfway milestone on the 140-turbine project, Cadeler said.
Once fully installed and commissioned in the summer of 2023, Hollandse Kust Zuid will become the largest operating offshore wind farm, as well as the first one built without government subsidies.
I very much believe that in the near future many, if not all wind farms will be built without subsidy.
