The aim of the H2Ocean project is the development of an offshore platform which will harvest wind and wave power, using part of the energy on-site for multiple applications – including a multi-trophic aquaculture farm, and convert on-site the excess energy into hydrogen that can be stored and shipped to shore as green energy carrier. In the sub-project desalination the main task of IGB will be optimizing RO-membranes with low-fouling properties.
