COMPRESSED GAS ENERGY STORAGE AND RELEASE SYSTEM

摘要

A compressed gas energy storage and release (CGESR) system and method. The system has a gas compressor, a container for storing compressed gas, a pressure engine, and an underground high temperature region. Conduits connect the gas compressor, the container and the pressure engine. The compressed gas drives the pressure engine. An electrical power generating means is operatively connected to said pressure engine to generate electricity. The system further comprises a means to heat at least a portion of one of the conduits utilizing heat from the underground high temperature region to heat the compressed gas therein prior to driving the pressure engine.

1. A compressed gas energy storage and release (CGESR) system comprising:
a gas compressor for compressing gas; a container configured to store said compressed gas, said container being in communication with said gas compressor via a first conduit; a pressure engine in communication with said container via a second conduit, said pressure engine being driven by expansion of said compressed gas, thereby converting said compressed gas into mechanical work; an electrical power generating means operatively connected to said pressure engine, said electrical power generating means being configured to convert said mechanical work into electricity; an underground high temperature region positioned at a level below a surface of the earth; means to heat at least a portion of said first conduit or said second conduit utilizing heat from said underground high temperature region to form a heated compressed gas therein.
