Energy storage is a technology that holds energy at one time so it can be used at another time. Building more energy storage allows renewable energy sources like wind and solar to power more of our electric grid .

Thermal energy storage (TES) systems provide both environmental and economical benefits by reducing the need for burning fuels. Thermal energy storage (TES) systems have one simple purpose. That is preventing the loss of thermal energy by storing excess heat until it is consumed. Almost in every human activity, heat is produced.
