UK and Europe Sign Hamburg Declaration to Deliver 100GW North Sea Offshore Wind

The UK and several European nations have signed the Hamburg Declaration, a landmark clean energy security pact designed to accelerate offshore wind cooperation across the North Sea.

Agreed at the Future of the North Seas Summit in Hamburg, the deal commits participating countries to jointly deliver 100 GW of offshore wind capacity by 2050 through cross border projects. The move comes amid ongoing geopolitical instability and aims to strengthen regional energy security while reducing reliance on volatile fossil fuel markets.

The agreement marks the first time North Sea countries have formally committed to delivering a defined share of their broader 300 GW offshore wind target through joint projects. A key feature of the declaration is the development of offshore hybrid assets, wind farms connected to more than one country through interconnectors. This approach is expected to improve grid efficiency, lower infrastructure costs and allow clean electricity to flow to where it is needed most.

The UK is positioning itself at the forefront of the pledge following a record breaking offshore wind auction that secured 8.4 GW of capacity and attracted billions in private investment. The pact also outlines closer cooperation on interconnected offshore grids, joint planning frameworks and collaboration with countries including Germany, Belgium, Denmark and the Netherlands to speed up delivery.

Industry leaders have welcomed the declaration, describing it as a major step toward transforming the North Sea into a shared clean energy hub. They stress that continued UK and EU alignment on electricity markets, supply chains and infrastructure will be critical to delivering affordable, secure and low carbon power for households and businesses across the region.

A 100 GW North Sea offshore-wind commitment reshapes European renewable supply-chain planning through 2035 - installation vessels, port infrastructure, grid connections, PPA availability all get repriced.
