Water sorption-based thermochemical storage materials: A review from material candidates to manufacturing routes

A comprehensive and updated review is provided in this article, with a focus on water sorption-based thermochemical storage (WSTCS) materials, covering materials their manufacturing routes. The state of the art 22 most relevant salt hydrates classified into seven groups (bromides, sulphates, carbonates, chlorides, nitrates, hydroxides, sulphides) studied as candidates. This followed by discussion TCS material manufacturing, both conventional (shaping, pelletizing, etc. ) more advanced routes (e.g., extrusion, 3D printing, encapsulation, ). Finally, concluding remarks are presented, including limitations future potentials for research.
