High-pressure hydrogen storage for on-board applications and for coupling renewable energies to the electric grid

This paper deals with hydrogen storage issues and reports the high-pressure technological advancement performed to date at a laboratory scale in two distinct domains. For on-board storage applications, the developments enter the scope of the adsorption approach that relates to materials exhibiting high specific areas and microporous volumes; experimental results connected to a specific device operating under pressures up to 70MPa are presented. For renewable energy sources, the development aims to reassess the coupling to the electric grid of those suffering from inherent variability; pressurized hydrogen in dedicated pipeline sections is therein considered as a buffer storage means. The latter part presents the recently developed distribution-related pipe section test bench, previously designed for testing under monotonic loading up to 30MPa or under cyclic loading between 4 and 10MPa, that the new development shall benefit from.
