A recent study conducted by the Fraunhofer Institute for Energy Economics and Energy System Technology IEE has delved into the potential economic impacts of incorporating offshore hydrogen production into the European energy system, with a focus on Germany. The study specifically evaluates the effects of establishing offshore hydrogen production on energy islands connected to offshore wind farms, compared to a scenario where all electricity generated from offshore wind is transmitted to shore without additional hydrogen production. The findings reveal that Germany could reap annual savings of up to 4.3 billion Euros by implementing offshore hydrogen production on these energy islands. The study highlights that the proximity of hydrogen production to the renewable energy source offshore results in enhanced efficiency and cost savings. By situating the production facilities near the energy generation sites, the need for extensive grid infrastructure, particularly costly cables to transmit electricity from the coastline to inland regions, is significantly reduced. Additionally, the study underscores that offshore hydrogen production proves to be more effective than onshore methods, as it minimizes energy loss and eliminates substantial investments in long-distance electricity transportation. Moreover, the research emphasizes the advantages of connecting offshore hydrogen production to the grid through a limited grid connection. This setup allows for flexible utilization of energy, enabling the produced electricity to be utilized for hydrogen production or transmitted to the mainland as needed. The flexibility provided by this approach enhances the overall efficiency and resilience of the energy system, with the ability to adjust energy usage based on market conditions and supply-demand dynamics. In conclusion, the study underscores the significant benefits of offshore hydrogen production in terms of economic savings, efficiency gains, and increased flexibility in the utilization of renewable electricity within Germany's energy system.
