ABSTRACT:
A method is disclosed for storage of energy produced at a conventional power station and release of said energy when subsequently required. The method comprises using the energy to refrigerate and liquefy atmospheric nitrogen and oxygen, storing the liquid gases at substantially below atmospheric temperature and subsequently using cold liquid gas, in combination with a source of heat at or above atmospheric temperature, to drive a closed cycle heat engine and yield mechanical energy. Auxiliary open and closed cycle heat engines are added to yield further mechanical energy and so utilize the full energy potential of the cold liquid gases.
