4C Offshore Empowering Intelligence
28 Oct 2022: The Federal Maritime and Hydrographic Agency (BSH) published second draft of an updated development plan (FEP). The 2nd draft contains changes and consultation questions on co-use at sea, technical aspects of the grid connection and on development options for hydrogen production and test fields. Other generation area SEN-1 has been expanded from 27 km2 to 95.4 km2. A pipeline and route is not specified by the FEP but any future developer must meet requirement of at least 2 GW a pipeline. There is possibility to connect to an existing pipeline e.g. Europipe 1 pipeline which runs adjacent. The FEP is consulting splitting the area into two (SEN-1 and SEN-2). Responses from developers and industry bodies lobby for smaller staggered tenders to allow increased competition, risk spreading, testing multiple technologies and technology scaling.
