Rostock’s seaport is to be gradually developed into a large-scale hub for green hydrogen with an energy output of 1 gigawatt by 2030. The necessary renewable energies will be fed into the port mainly from offshore wind farms via the Bentwisch energy grid connection. The surplus heat generated during the conversion process will be supplied to the district heating network of Rostock municipal utilities for the district heating supply of the Hanseatic and university city.
