H2Mare has initiated a groundbreaking project in Bremerhaven, Germany, focusing on offshore production of green hydrogen and power-to-X (PtX) products from wind energy. The project partners, including KIT, DLR, and the Technical University of Berlin, have launched a floating test platform to showcase a complete PtX process chain for sustainable e-fuel production. The platform will demonstrate the conversion of green hydrogen and CO2 into e-fuels through Fischer-Tropsch synthesis, with components like a direct air capture system for CO2 extraction and a seawater desalination plant. Operating independently of the electricity grid, the platform will adapt to the varying availability of renewable energy sources. Insights gained from this research, including tests in Bremerhaven and Helgoland, are crucial for the future development of large-scale PtX facilities. The project not only focuses on the technical aspects but also considers maritime factors, material properties, and regulatory requirements. Additionally, H2Mare explores alternative PtX synthesis routes like liquid methane, methanol, and ammonia production. This initiative, supported by the German Federal Ministry of Research, Technology and Space, aligns with the country's hydrogen strategy to drive innovation in green energy and sustainable fuel production.
