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

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

This is the sub-heading.

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

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

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

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

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

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

Note.

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

These are my thoughts.

The Salamander Project

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

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

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

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

Bringing The Electricity South

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

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

Note.

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

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

What Will Happen To The Excess Electricity?

Consider.

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

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

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

Possible solutions would include.

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

Note.

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

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

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

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

Conclusion

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

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