The Nature of the Chemical Bond in Hydrogen Storage Compounds... 

Most hydrogen storage compounds such as LaNij, Mg Ni, CaNi and TiFe consist of both endothermic and exothermic elements in view of the heat of formation of their hydrides. For example, an exothermic element. La, has a strong attractive interaction with hydrogen and hence forms easily the hydride, LaH. The endothermic elements (e.g., Ni) may work to reduce such an attractive interaction, so that the hydrogen desorption process could be activated by the presence of them. 

The present approach is applicable to other hydrogen storage compounds. Here, two examples will be shown briefly.
