Offshore conversion of wind energy into chemical products using hydrogen from seawater and use of Carbon Dioxide.
The sea offers ideal conditions for generating renewable electricity. Direct production of green hydrogen from wind energy in offshore systems without grid integration can significantly reduce costs compared to onshore production. The H2Mare lighthouse project is therefore researching the offshore production of green hydrogen and other Power-to-X products (PtX).
H2Mare consists of four collaborative projects with a total of 32 partners from research and industry. The total budget of the project is more than 100 Millionen Euro.
Goals of the H2Mare subproject PtX-Wind
Unlocking the full potential of offshore wind energy to produce green hydrogen and PtX products derived from it
Analysis of different PtX process chains with different electrolysis technologies for the production of methane, carbohydrates, methanol and ammonia
Examination of the entire PtX process chain including the offshore supply of educts, the intermediate storage of energy and products as well as logistics
Experimental testing of an exemplary PtX process chain in the maritime environment with containerized subsystems
Development of a concept for a generic offshore PtX research platform and a digital twin
Identification of optimal system configurations and operating strategies for offshore island applications
Goals and tasks of the DLR Institute of Engineering Thermodynamics
Aims:
Demonstration and analysis of SOEC electrolysis directly from offshore wind energy
Tasks:
