Thermochemical energy storage is quite a new method and is under research and development phase at various levels (Prieto, Cooper, Fernández, & Cabeza, 2016 ). In this technique, the energy is stored and released in the form of a chemical reaction and is generally classified under the heat storage process.
Alternatively, heat can be stored by directing thermal energy to an endothermic chemical reaction. In this reaction, a thermochemical absorbs the energy and splits into separate substances, which can be stored until the energy is needed again.
Chemical energy storage in the form of biomass, coal, and gas is crucial for the current energy generation system. It will also be an essential component of the future renewable energy system. With each facility ranging in the terawatt-hours, chemical energy storage has by far the largest capacity.
Provided by the Springer Nature SharedIt content-sharing initiative Policies and ethics Thermochemical energy storage (TCES) is considered the third fundamental method of heat storage, along with sensible and latent heat storage. TCES concepts use reversible reactions to store energy in chemical bonds.
Thermochemical heat storage works on the notion that all chemical reactions either absorb or release heat; hence, a reversible process that absorbs heat while running in one way would release heat when running in the other direction. Thermochemical energy storage stores energy by using a high-energy chemical process.
