A recent study conducted by the Fraunhofer Institute for Energy Economics and Energy System Technology IEE has shed light on the potential economic benefits of offshore hydrogen production in Germany. The study focused on the impact of establishing offshore hydrogen production on two energy islands, each connected to 10 GW of offshore wind power. By comparing this scenario to transporting all offshore wind electricity to the mainland for general use, the study found that Germany could save up to 4.3 billion Euros annually. One key advantage highlighted in the study is the reduced grid buildout costs associated with offshore hydrogen production. By locating production sites closer to the energy source, particularly renewable offshore wind, the need for expensive grid infrastructure, such as long-distance cables to transport electricity, is minimized. This proximity leads to higher utilization of HVDC cables and reduces energy loss during transportation. The study also compared two scenarios: one with only a hydrogen pipeline connection to the islands and another with a limited grid connection in addition to the hydrogen pipeline. The latter scenario, which allows for flexible use of offshore wind energy either for hydrogen production or direct electricity supply to the grid, was found to offer significant efficiency gains. During periods of high renewable energy supply and low prices, electricity is diverted to hydrogen production; while during high-demand periods, wind energy is used to meet electricity needs directly. Overall, the findings suggest that offshore hydrogen production on energy islands not only presents economic advantages but also contributes to grid efficiency, environmental sustainability, and the overall transition to renewable energy sources. The study underscores the importance of integrating offshore hydrogen production into the energy system to maximize benefits and create a more flexible and efficient energy infrastructure in Germany.
