what is needed for compressed air energy storage
Solved 1. One can store energy by compressing air and use it
1. One can store energy by compressing air and use it later to power a turbine to create energy when needed. The air must be heated to make this, effective, which can be accomplished by compressing the air under adiabatic conditions. This is called adiabatic compressed air energy storage (CAES).
