System to store and retrieve stored energy - has gas type auxiliary energy storage medium which is liquefied when energy requirements are low

摘要

A method to supply energy consumers with energy produced by generator which in times of low energy consumption stores part of the energy produced by means of a gas type auxiliary energy carrying agent is constructed such that in time of low energy requirement the auxiliary energy carrying medium is liquefied and stored under almost no pressure condition. During times of large energy requirement the auxiliary energy transport medium is vapourised, heated up and efficiently expanded. A gas turbine, compressor, cooler and reactor may be incorporated in the closed cycle.
