Abstract: 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.
