Within the framework of the joint project H2Wind, the scientific fundamentals of a quasi-autonomous offshore hydrogen production along a sustainable value chain are to be investigated. For a sustainable offshore production of hydrogen, a novel, compact PEM water electrolysis is necessary. At the same time, both an appropriate offshore water treatment for the electrolysis and a storage option for the produced hydrogen gas will be investigated.
The overall objective of the subproject H2Wind - LUH is the experimental and model-theoretical support of the development of a membrane electrode unit optimized for the special offshore conditions. For this purpose, experiments with 4 cm2 cells as well as with site-expanded single-channel cells are performed. The model-theoretical accompaniment includes a spatially distributed consideration of the membrane-electrode unit.
