Abstract
Heat storage systems based on two-tank thermochemical heat storage are gaining
momentum for their utilization in solar power plants or industrial waste heat recovery since
they can e ciently store heat for future usage. However, their performance is generally limited
by reactor configuration, design, and optimization on the one hand and most importantly on the
selection of appropriate thermochemical materials. Metal hydrides, although at the early stage of
research and development (in heat storage applications), can o er several advantages over other
thermochemical materials (salt hydrates, metal hydroxides, oxide, and carbonates) such as high
energy storage density and power density. This study presents a system that combines latent heat
and thermochemical heat storage based on two-tank metal hydrides. The systems consist of two
metal hydrides tanks coupled and equipped with a phase change material (PCM) jacket.
