Implementation of offshore electrolysis for optimized offshore expansion in zones 4 and 5 based on mixed connection concepts consisting of submarine cables and pipelines

The ongoing development of offshore wind energy in Germany requires an efficient and forward-looking grid connection in order to make the best possible use of the renewable electricity generated, to achieve the offshore wind expansion and climate protection targets and to accelerate the ramp-up of the hydrogen economy. The Hydrogen Rowing Boat is committed to the increased integration of offshore electrolysis into maritime area development planning in order to minimize grid bottlenecks, increase economic efficiency and adapt the regulatory framework accordingly. Therefore, in view of the current optimization of offshore wind expansion, a system-integrated overall concept is required for zones 4 and 5 of the German Exclusive Economic Zone (EEZ), which enables an economically sensible, balanced and practicable implementation of the measures currently under discussion, such as reduction of power densities, overbuilding and peak capping as well as offshore electrolysis. In addition, it should be shown how and where the energy should be transported using offshore electrolysis hubs based on combined connections from submarine cables and pipelines .
