The Mittelplate drilling platform with supply ships.
H2Move (abgeschlossen)
The Mittelplate oil field is the most productive oil field in Germany and has been operated by Wintershall Dea for 35 years. The field is located in the Schleswig-Holstein Wadden Sea, which is why it is planned to operate it in the most environmentally friendly way possible. In the H2Move project, the Mittelplate Drilling and Production Island's supply ships are to be converted to hydrogen hybrid drives. The hydrogen required for this is to be produced in aCO2-neutral manner in Cuxhaven.
News (15.11.2023): 2-megawatt electrolyzer now producing green hydrogen for shipping
On November 15, a 2-megawatt electrolysis plant was put into operation in Cuxhaven, which is now producing green hydrogen for shipping. The green hydrogen is to be used in the H2Move project, as part of which supply vessels on the Mittelplate drilling and production island will be converted to hydrogen hybrid propulsion. Turneo Managing Director Jochen Kaufholt, Tobias Moldenhauer (EWE), Robert Frimpong (Wintershall Dea Deutschland), Cuxhaven's Lord Mayor Uwe Santjer and Lower Saxony's Minister of Economic Affairs Olaf Lies were among those present at the official commissioning of the electrolysis plant and the first converted supply vessel Coastal Liberty.

News (14.09.2023): Electrolysis plant is in assembly/commissioning!
The 2 MW electrolysis plant was delivered to Cuxhaven just under a month ago. Following successful installation and commissioning, it will be possible to achieve a production capacity of up to 860 kg H2/day. At the filling station, which has also been installed, the hydrogen will be filled into bundles of cylinders and transported onto ships, thus protecting the Wadden Sea with the help of a fuel cell.
An electrolysis plant with a capacity of 2 megawatts is currently being built in Cuxhaven for the production of green hydrogen. This is to be used by the supply ships on Mittelplate Drilling and Production Island. In addition, storage tanks with different pressure levels are being built in Cuxhaven to enable the refueling processes to be carried out as quickly as possible.
Once the plant has been completed, it is planned to transport the hydrogen produced in Cuxhaven to the Mittelplate ships in so-called tank containers under a pressure of up to 350 bar. The hydrogen will then be fed from the containers to a fuel cell, which will generate electricity and ultimately drive the electric motor of the Mittelplate vessels.
According to Wintershall Dea, the four supply vessels in the Mittelplate fleet cover a combined distance of about 12,500 nautical miles annually. The first supply vessel to be converted is the Coastal Liberty. This ship alone consumes around 275,000 liters of diesel per year and has the potential to save up to 700 tons ofCO2 annually.
The development and implementation of the onshore supply infrastructure is being implemented by Turneo GmbH, a joint venture between Hamburg-based Karlsson GmbH and EWE Gasspeicher GmbH from Oldenburg. The company EnTec Industrial Services GmbH had previously successfully completed a feasibility study in Cuxhaven. The project will ultimately also lay the foundation for the development of a regional hydrogen infrastructure in Cuxhaven.
