Abstract
A method and apparatus for storing excess electricity generated during off-peak periods. The electricity is used to run compressors which compress the air in a plurality of stages. The air is cooled after each stage to remove the heat of enthalpy. The air is stored in bags on the bottom of the sea. To recover the energy, the compressed air is run through turbines and the heat removed during compression is reintroduced.
