In order to use hydrogen as an efficient energy carrier, even today technical efforts must be carried out into the H2 Generation-Storage-Use chain. Specifically, in the field of storage, although compressed gas and cryogenic liquid are the best known ways for hydrogen confinement due to the industry experiences, there is another promising way for hydrogen storage by the use of chemical systems like metal hydrides, carbon-based materials, or metal organic frameworks (MOFs) among others [1], [2]. In this point, hydride forming materials are well known and moderate operative conditions of pressure and temperature are the main advantages of this way in comparison with compressed or cryogenic H2. Although commercial storages based on metal hydrides are available, the practical application of this storage option still needs an optimization step in order to know real durability, hydrogen flow capacities, charging times or thermal requirements, especially when the hydride material is scaled from milligrams to hundred of grams or kilograms [3].
