The H2Mare project aims to establish a whole new type of turbine at sea in the future – a solution which integrates an electrolyser into an offshore wind turbine optimally for direct conversion of the electricity.
In addition, the project will also investigate further offshore power-to-X processes. This will involve consideration of the entire value creation chain: from wind energy generation and hydrogen production to the conversion of hydrogen into methane, liquid hydrocarbons, methanol, or ammonia right up to use in industry or the energy sector.
Siemens Energy is responsible for the coordination of H2Mare and is supported by institutes of the Fraunhofer Gesellschaft. The four H2Mare projects are being promoted independently of each other:
OffgridWind: Pursues the implementation of a turbine concept that realizes electrolysis directly in the offshore wind turbine,
H2Wind: Consists in the development of a PEM (proton exchange membrane) electrolysis system optimally adapted to the offshore environment and tuned to the wind turbine. In addition to the durability of the turbines and the challenge of processing seawater, the maximum yield of wind energy is one of the project’s goals.
PtX-Wind: In contrast to pure offshore hydrogen production, the focus here is on conversion to more easily transportable, synthetic energy carriers and fuels, such as methane, methanol, and ammonia. The power-to-X products are produced via high-temperature electrolysis and CO2 extraction from the air or sea. Direct saltwater electrolysis is also being tested.
TransferWind: TransferWind addresses the transfer of knowledge to the public as well as the exchange of expertise across projects. At the same time, it also considers safety and environmental issues as well as infrastructure requirements.
