Thermochemical Storage Materials: This approach involves endothermic and exothermic chemical reactions for energy storage and release. These materials, such as metal hydrides and calcium oxide, can store heat over a long period without significant losses. TES systems have versatile applications across numerous sectors:
During discharge, the thermal energy storage material transfers thermal energy to drive the heat pump in reverse mode to generate power, as well as lower-grade heat that can be used in various other applications.
Classification of thermochemical energy storage by the reaction type. Thermochemical storage materials should be characterized by a suitable reaction temperature and enthalpy for the application. Further material requirements are listed in Section 1.1.
Typically, thermochemical energy storage refers to two main processes, thermochemical reactions and sorption processes. Thermal adsorption reactions can be used to store heat or cold in the bonding of a substance to another solid or liquid. A common sorption process used in TCS systems is the adsorption of water vapor to silica gel or zeolites.
Various modes of thermal energy storage are known. Sensible heat storage represents the thermal energy uptake owing to the heat capacity of the materials over the operational temperature range. In latent-heat mode, the energy is stored in a reversible phase transition of a phase change material (PCM).
For discharging, in the exothermic reaction, the gas is recombined with the solid. In general there are various types of solid–gas reaction systems that can be used for thermochemical energy storage as follows: Thermal desoxygenation of metal oxides (application in the range of 600°C–1000°C)
