Plans for a 650-800MW offshore wind farm that would be fully integrated into a major new bridge linking Denmark with north east Germany have been been drawn up by developer, Wind-projekt.
The Baltic Energy Bridge proposal foresees a 43km road and rail bridge linking Rostock on the German Baltic Sea coast to Denmark via Gedser on the Danish island of Falster. The bridge would reduce travelling times between Copenhagen and Berlin while simultaneously generating electricity, thanks to up to 60 turbines that would be built along the route.
Wind-projekt foresees turbines with a rated power of 10-12MW and operating at more than 4000 full load hours per year. Their location adjacent to the bridge route would simplify access enormously, argues the developer. The project could also include hydrogen production via an electrolysis system. This would be fed into a gas pipeline running alongside both the road and the electricity transmission cable. Hydrogen filling stations for vehicles would be built close to landing points on both sides and an underground hydrogen storage facility could be built near Rostock.
Oxygen produced during the electrolysis process could be pumped into the Baltic Sea to counter prevalent under-oxygenation, notes Wind-projekt.
Last December, the developer lodged an application for electricity transmission to shore with transmission system operator (TSO) 50Hertz.
The Baltic Energy Bridge proposal revives an idea for a Germany–Denmark link once discussed as an alternative to a now-planned link between the two countries due to run via the German island of Fehmarn. A letter of intent was signed in June 2007 by the Danish and German transport ministers in favour of the Fehmarn proposal. The German transport ministry's website currently states that the Fehmarn link will not come into operation before the end of 2021 "due the extremely complex preparations for the permitting procedures in Germany and Denmark."
Wind-projekt was involved in early development of Baltic 1 offshore wind farm, commissioned since May 2011, as well as Baltic 2. Both projects are now owned by German utility, EnBW.
