Offshore wind power potential in Germany seen at over 60 GW

September 24 (Renewables Now) - Germany has the potential to install more than 60 GW of offshore wind power if all available options are used and this could be used for the production of substantial amounts of green hydrogen, shows an analysis published by Foundation Offshore Wind Energy.

Germany plans to expand its offshore capacity to 40 GW by 2040 from currently 7.5 GW, but if it uses its full potential, the excess wind power could produce more than 1.3 million tonnes of green hydrogen annually, or up to 44.2 TWh, according to the analysis. This would be more than the green hydrogen target set in the country's National Hydrogen Strategy of 28 TWh by 2035/40.

The estimates are based on the assumption for 8 MW installed capacity per square kilometre under the current maritime spatial plan and do not take into account territorial sea where the potential is seen at 2 GW and the Dogger Bank shallow area of the North Sea which could add a further 4-6 GW.

Against this backdrop, the next German government must set binding targets, designate enough sea areas for hydrogen production in addition to those meant for electricity generation and come up with an expansion path for offshore wind as soon as possible, according to Karina Wuertz from the Varel-based foundation.
