The Mittelplate drilling platform with supply ships. 


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-Elektrolyseur erzeugt ab sofort grünen Wasserstoff für die Schifffahrt

Am 15. November wurde in Cuxhaven eine 2-Megawatt-Elektrolyseanlage in Betrieb genommen, die ab sofort grünen Wasserstoff für die Schifffahrt produziert. Der grüne Wasserstoff soll im Projekt H2Move zum Einsatz kommen, in dessen Rahmen Versorgerschiffe der Bohr- und Förderinsel Mittelplate auf Wasserstoffhybridantrieb umgerüstet werden. Bei der offiziellen Inbetriebnahme der Elektrolyseanlage sowie des ersten umgerüsteten Versorgungsschiffes Coastal Liberty nahmen u.a. Turneo-Geschäftsführer Jochen Kaufholt, Tobias Moldenhauer (EWE), Robert Frimpong (Wintershall Dea Deutschland), Cuxhavens Oberbürgermeister Uwe Santjer und Niedersachsens Wirtschaftsminister Olaf Lies teil.

News (14.09.2023): Elektrolyseanlage befindet sich in Montage/Inbetriebnahme!

Die 2 MW-Elektrolyseanlage wurde vor knapp einem Monat in Cuxhaven abgeliefert. Damit wird es möglich sein, nach der erfolgreichen Montage und Inbetriebnahme, eine Produktionskapazität von bis zu 860 kg H2/Tag zu erreichen. An der ebenfalls installierten Tankstelle wird der Wasserstoff in Flaschenbündeln abgefüllt und auf Schiffe transportiert, mithilfe einer Brennstoffzelle wird das Wattenmeer somit geschont.

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.
