Sammendrag
In this work we test the potential of thermochemical energy storage (TCES) for waste-heat recovery in industry processes. Different TCES technologies were considered, finding sorption TCES the most promising. The temperature range of TCES sorption technologies is extensively wide, so this work focuses on the most unexplored range, 100-300°C, which also fits the heat generated in several industry processes. The hydrate salt MgCl 2 was incorporated into alumina, obtaining a heat storage capacity >500 kJ/kg. Through the results from this work and follow-up studies, we will facilitate the industrial uptake of water-sorption thermochemical energy storage materials and technologies.
