    Abstract

    Some of the magnesium properties essential to the applicability of the reaction Mg+H2⇆MgH2 as a hydrogen storage system have been investigated. Three magnesium powders with particle size smaller than 50 μm average diameter were cycled, over 31, 71 and 151 cycles respectively, at 675K (400°C) and at absorption pressures, 2-3 MPa. The powders absorbed and desorbed 60-95% of the theoretically maximal amount of hydrogen given by stoichiometric MgH2. The reaction rates changed negligibly over the extent of the experiments permitting the mentioned hydrogen exchange to be completed in less than 20 minutes. A high capacity, automatic cycling facility suitable for a more comprehensive investigation of the long term capacity parameters has been constructed and tested but not yet applied
