Scotland And AquaVentus Partner On North Sea Hydrogen Pipeline Plans

The title of this post, is the same as that of this article on H2-View.

These four paragraphs introduce the deal and add some detail.

Hydrogen Scotland has committed to working with the AquaDuctus consortium on cross-border infrastructure concepts to connect Scotland’s offshore wind power to hydrogen production in the North Sea.

Under a Memorandum of Understanding (MOU), the two organisations plan to combine Scotland’s offshore wind with AquaVentus’ offshore electrolysis expertise, linking export and import goals across the North Sea.

The AquaDuctus pipeline is a planned offshore hydrogen link designed to carry green hydrogen through the North Sea, using a pipes and wires hybrid approach. The German consortium plans 10GW of offshore electrolysers in the North Sea, producing around one million tonnes of green hydrogen.

The pipeline design allows offshore wind farms to deliver electricity when the grid needs it, or convert power into hydrogen via electrolysis and transport it through pipelines.

Germany is embracing hydrogen in a big way.

• I introduce AquaVentus in AquaVentus, which I suggest you read.
• AquaVentus is being developed by RWE.
• AquaVentus connects to a German hydrogen network called H2ercules to actually distribute the hydrogen.

This video shows the structure of AquaVentus.

I clipped this map from the video.

Note.

1. The thick white line running North-West/South-East is the spine of AquaVentus, that will deliver hydrogen to Germany.
2. There is a link to Esbjerg in Denmark, that is marked DK.
3. There appears to be an undeveloped link to Norway, which goes North,
4. There appears to be an undeveloped  link to Peterhead in Scotland, that is marked UK.
5. There appears to be a link to just North of the Humber in England, that is marked UK.
6. Just North of the Humber are the two massive gas storage sites of Aldbrough owned by SSE and Rough owned by Centrica.
7. Aldbrough and Rough gas storage sites are being converted into two of the largest hydrogen storage sites in the world!
8. There appear to be small ships sailing up and down the East Coast of the UK. Are these small coastal tankers, that are distributing the hydrogen to where it is needed?

When it is completed, AquaVentus will be a very comprehensive hydrogen network.

I believe that offshore electrolysers could be built in the area of the Hornsea 4, Dogger Bank South and other wind farms and the hydrogen generated would be taken by AquaVentus to either Germany or the UK.

• Both countries get the hydrogen they need.
• Excess hydrogen would be stored in Aldbrough and Rough.
• British Steel at Scunthorpe gets decarbonised.
• A 1.8 GW hydrogen-fired powerstation at Keadby gets the hydrogen it needs to backup the wind farms.

Germany and the UK get security in the supply of hydrogen.

Conclusion

This should be a massive deal for Germany and the UK.
