Thermal Energy Storage
The term ''thermal-energy storage'' also includes heat and cold storage. Heat storage is the reverse of cold storage. Heat storage absorbs energy during charging, and cold storage releases energy in the form of heat during charging. If the energy stored is at a temperature below ambient temperatures, the system is called cold storage.
