The Vision of France, Germany, and the European Union on Future Hydrogen Energy Research and Innovation

Abstract Hydrogen (H2) is an essential vector for freeing our societies from fossil fuels and effectively initiating the energy transition. Offering high density, hydrogen can be used mobile, stationary, or industrial applications of all sizes. This perspective on crucial role shared by a growing number countries worldwide (e.g., China, Germany, Japan, Republic Korea, Australia, United States), which are publishing ambitious roadmaps development fuel cell technologies, supported substantial financial efforts.
