Comparison of energy storage capabilities of vermiculite-based composite materials impregnated with different sorbents

In recent years, energy storage has become increasingly important for the continuous and efficient use of energy due to the increasing demand for energy day by day following the effect of the increasing population along with developing and changing technologies. In this study, composite sorbents were produced by salt impregnation for thermochemical energy storage (THS). Vermiculite was used as structural support for two different sorbent salts (CaCl2, LiCl). Thermal energy storage capacities of the composites were characterised using a Differential Scanning Calorimetry (DSC). The results obtained here compared with the results obtained from the laboratory scale thermochemical heat exchanger prototype system.
