Abstract
A method for the preparation of active magnesium hydride-magnesium-hydrogen storage systems, which absorb hydrogen reversibly is disclosed. Finely divided magnesium is doped with nickel for this purpose. A pressure reactor is charged with a mixture of finely divided magnesium and an amount of nickel sufficient for the doping. Tetracarbonyl nickel is produced in the pressure reactor and subsequently decomposed. Carbon monoxide is then withdrawn from the pressure reactor and the doped magnesium obtained is hydrogenated at temperature of .gtoreq.300.degree. C. and elevated pressure.
