Sorption Thermal Energy Storage | SpringerLink
Sorption TES belongs to the wider class of thermochemical energy storage. The definition ''sorption'' was first reported by McBain [ 1] in 1909 to describe the interaction occurring between a gaseous sorbate and a liquid or solid sorbent. The former interaction was identified as absorption while the latter as adsorption.
