How does a thermal energy storage system work?

The thermal energy storage system is loaded by transferring the heat transfer fluid from the solar field or tower to the salt via a heat exchanger. For this purpose, the cold liquid salt is conveyed from the cold storage tank and transported in countercurrent through the heat exchanger, where it heats up.

Can solar energy be stored as thermal energy?

Thermal energy supplied by solar thermal processes can be in principle stored directly as thermal energy and as chemical energy (Steinmann, 2020) The direct storage of heat is possible as sensible and latent heat, while the thermo-chemical storage involves reversible physical or chemical processes based on molecular forces.
