Fraunhofer ISIT Contributes Key Expertise in Maritime Hydrogen Energy Systems

Press release /

The international research project OceanH2 has been officially endorsed as a “Decade Project” under the UN Ocean Decade by the Intergovernmental Oceanographic Commission (IOC) of UNESCO. This recognition places OceanH2 among a selected group of global initiatives addressing critical challenges related to the ocean, energy, and sustainability.

OceanH2 aims to develop and demonstrate technologies for the offshore production of green hydrogen for multi-use applications. The project focuses on integrated energy systems that efficiently combine renewable energy generation, hydrogen production, storage, and utilisation under demanding maritime conditions.

Fraunhofer Institute for Silicon Technology ISIT plays a key role in the project, contributing its expertise in power electronics and energy systems integration. Within Work Package 3, the institute develops advanced modelling approaches for offshore power electronic systems and corresponding control strategies. The objective is to ensure stable and efficient interaction between renewable energy sources, electrolyzers, and energy storage systems, even under highly dynamic and site-specific offshore conditions.

A particular focus lies on the simulation and validation of power electronic converters designed for offshore microgrid applications. This includes the selection of suitable converter topologies, the design of robust control loops, and hardware-in-the-loop testing to evaluate system performance under realistic operating scenarios.

“The recognition within the UN Ocean Decade highlights the international relevance of our work in maritime energy systems,” says Prof. Dr.-Ing. Marco Liserre, Fraunhofer ISIT.
“In particular, the integration of hydrogen technologies into complex offshore energy systems requires advanced approaches in power electronics and system control – this is where we contribute our expertise.”

By joining the UN Ocean Decade, OceanH2 becomes part of a global network of stakeholders from research, industry, and policy working towards sustainable ocean solutions. The endorsement further strengthens the visibility of European research efforts in the field of climate-neutral energy systems.
