A recent white paper from the BMBF's hydrogen flagship project TransHyDE System Analysis, coordinated by Fraunhofer IEG and DECHEMA e.V., highlights Europe's future hydrogen demand and infrastructure needs. The research projects a minimum requirement of 700 TWh of hydrogen in 2050, driven primarily by the steel and chemical industries. The transportation sector, especially international aviation and shipping, is also expected to heavily rely on hydrogen-based green fuels. The study emphasizes the importance of aligning hydrogen availability with specific industry needs and the establishment of a pan-European hydrogen backbone network. Electrolysis is identified as a key technology for ensuring a continuous hydrogen supply for industrial processes. The research also underlines the potential role of repurposing natural gas pipelines and the importance of imports, particularly from the MENA region, to meet hydrogen demand. A collaborative effort involving various research institutions and organizations is essential to shape Europe's hydrogen economy and infrastructure for a sustainable energy transition.
