Thermal energy storage (TES) allows the transfer and storage of heat energy, by means of a thermal reservoir. The thermal energy stored can then be used later. A typical example used for cooling is to run a refrigeration plant overnight using cheaper off peak electricity, then during the day the refrigeration plant is cycled off and the energy used in the ice is used for cooling, thus avoiding using more expensive peak electricity. Glaciem’s thermal energy storage solution, Thermcold, makes use of special phase change materials to allow thermal storage at previously unheard of temperatures.
