What is thermal energy storage? – 5 benefits you must know

What is thermal energy storage? Thermal energy storage means heating or cooling a medium to use the energy when needed later. In its simplest form, this could mean using a water tank for heat storage, where the water is heated at times when there is a lot of energy, and the energy is then stored in the water for use when energy is less plentiful.

HVAC: Cool Thermal Storage

Thermal energy storage (TES) for HVAC applications is a way of utilizing the cheap electrical energy during lean periods to produce thermal energy when it is not needed (or is less expensive to produce). Here''s how TES Works The concept behind TES is simple. Water is cooled by chillers during off-peak * hours and stored in an insulated tank.
