Thermal energy, especially solar heat, is converted into chemical energy by being used for the endothermic dissociation of a compound which is exothermically recombinable to release at least a substantial part of that energy at a time and/or location at which the original heat source is not readily available. One or more of the dissociation products are transported to the point of utilization, preferably after interim storage, and are there recombined with one another and/or with locally available reactants to restore the original compound which is then returned, again preferably after interim storage, to the dissociation site for a repetition of the process. The exothermic reaction at the recombination site may be used to decompose a locally available compound, e.g. water, for the purpose of liberating one of its constituents, e.g. hydrogen.
