A short review of R&D in the field of hydrogen hydride technologies in Russia and CIS countries is presented. As a result of basic research of physical and chemical features of intermetallic alloys and their hydrides, their structural peculiarities, absorption kinetics, thermal processes, etc., methods have been developed for creation high efficient alloys for different applications in metal hydride technology. Original devices such as hydrogen accumulators, thermal compressors, heat transformation systems and other experimental devices with unique characteristics have been created. The results of reviewed R&D demonstrate high efficiency of metal hydride technologies. These investigations and developments give reliable scientific and technical background for the development of the new research projects in the framework of the new Russian program of R&D in hydrogen energy and technology and for international cooperation.
