Gwynt Glas Offshore Wind Project Strengthens Development And Welcomes New Partner, Sumitomo

The title of this post, is the same as that of this news item from Gwynt Glas.

These three initial paragraphs add some detail.

The Gwynt Glas offshore wind project has today announced a significant strengthening of its joint venture with Sumitomo Corporation joining as an equal partner alongside EDF power solutions UK and Ireland and ESB. Each partner now holds a 33.33% stake, while DP Energy continues to provide critical development support, leveraging its expertise in early stage project delivery and local engagement.

This strategic collaboration brings together three global leaders in renewable energy combining deep expertise in large scale development and delivery. The partnership positions Gwynt Glas to advance confidently through its next phases, reinforcing its role in delivering clean, homegrown energy for Wales and the UK while supporting energy security and economic growth.

Gwynt Glas is a proposed innovative floating offshore wind farm in the Celtic Sea. The up to 1.5 GW project continues to make strong progress and successfully submitted its Scoping Report to the Planning Inspectorate this summer.

Are Sumitomo Involved In Offshore Wind?

I asked Google AI, the question in the title of this section and received this answer.

Since making its first investment in a European offshore wind project in 2014, Sumitomo Corporation
has accumulated extensive expertise throughout the development, construction and operation phases of offshore wind projects.

This marks Sumitomo Corporation’s first participation in a floating offshore wind project.

Are Sumitomo learning about floating offshore wind, by participating in a major project or are they up to something very innovative technically?

In Is Sumitomo Heavy Industries Highview Power Energy Storage System On Line At Hiroshima?, I talked about how Sumitomo’s engineers had taken Highview Power’s ideas for energy storage using liquid-air and downsized it to improve the efficiency of an LNG Terminal at Hiroshima, by adding a 4MW/20 MWh battery.

I just wonder, if some of the steel floats that will support the wind turbines, will also be used for liquid-air tanks as part of one of Highview Power’s batteries. As initially, there will be 66 turbines at Gwynt Glas, the battery could be a monster, but a very environmentally-friendly one!
