THE CHOICE OF SYSTEMS FOR REGENERATING HEAT OF METALHYDRIDE ELEMENTS OF THERMOSORPTION HEAT CONVERTERS IN HYDROGEN ENERGETICS

The use ofecologically clean metalhydride power and heat pump plants utilizing heat from natural sources, is considered as a prospective trend in hydrogen energetics. The factors influencing the efficiency of operation of metalhydride devices of power and cooling plants are revealed, of which heat regeneration in a thermochemical cycle is shown to be the major factor. Methods of and devices for regeneration of heat accumulated in metalhydride elements are proposed and their efficiency is demonstrated.
