TES (Thermal energy storage) can enhance energy systems by reducing environmental impact and increasing efficiency. Thermochemical TES is a promising new type of TES, which permits more compactness storage through greater energy storage densities. In this article, closed and open thermochemical TES is investigated using energy and exergy methods.
The closed system consists of a working fluid and a thermochemical material where internal substances are separate from the heat transport fluid. Thermal energy from an energy resource, which provides the energy for dissociation of the thermochemical material, is transferred to a working fluid.
