Properties and applications of metal hydrides in energy conversion systems

Abstract

Structural, thermodynamic, and kinetic properties and phase diagrams of hydrogen in metals and alloys are presented in relation to materials development for the ‘hydrogen energy technology'. Among the materials considered special attention is paid to the hydrides of Li, Mg, Y, V, Nb, U, TiFe, and LaNi₅. It is shown how these materials are utilized for the production of hydrogen by water splitting, stationary and mobile storage, heat pumps and heat storage, heat engines, fusion-reactor technology, and hydrogen-isotope separation.
