What is energy storage and how does thermal energy storage

How Thermal Energy Storage Works. Thermal energy storage is like a battery for a building''s air-conditioning system. It uses standard cooling equipment, plus an energy storage tank to shift all or a portion of a building''s cooling needs to off-peak, night time hours. During off-peak hours, ice is made and stored inside IceBank energy storage tanks.
