Compressed Air Energy Storage (CAES) is a way of storing energy for future usage, primarily energy generated at off-peak (lower cost) times for use at on-peak (higher cost) times. Methods of storage include use of electrical or wind power to compress air into underground ‘mines’ made of solids such as concrete or stone, or fluids such as hot oil or molten salt. Once removed from storage, the air must be expanded via air engine or turbine before being used to power a generator or even a car such as the Tata ONE Car. CAES is still a subject of ongoing study to determine the most efficient practices.
