The invention relates to a safe hydrogen-storing tank that is easy to manufacture and enables the quick kinetic absorption of hydrogen, which reduces the variations in volume and has a low cost in terms of material and energy. The invention has the aim of providing a tank for storing hydrogen, including a hydrogen inlet () and a hydrogen outlet () in fluid communication with at least one solid body (-) capable of the exothermal absorption and endothermal desorption of hydrogen, wherein said at least one solid body (-) is made of a compacted material containing light metal hydride and a heat-conducting matrix, and wherein said at least one solid body (-) is in heat-transfer relation with at least one heat recovery material () free from salt or molten-salt compounds and capable of absorbing the heat generated by the hydrogen absorption and of releasing said absorbed heat so as to provide heat for hydrogen desorption.

Adiabatic tank for metal hydride

The invention relates to a method for preparation of a material adapted to reversible storage of hydrogen, including steps consisting of providing a first powder of a magnesium-based material, hydrogenating the first powder to convert at least part of the first powder into metal hydrides, mixing the first hydrogenating powder with a second powder additive, the proportion by mass of the second powder in the mix obtained being between 1% and 20% by mass, wherein the additive is formed from an alloy with a centred cubic structure based on titatnium, vanadium and at least one other metal chosen from chromium or manganese, and grinding the mix of first and second powders.
