Abstract. A compressed air energy storage (CAES) system is an electricity storage technology under the category of mechanical energy storage (MES) systems, and is most appropriate for large-scale use and longer storage applications. In a CAES system, the surplus electricity to be stored is used to produce compressed air at high pressures.

This paper explores a new idea for electrical energy storage that is similar to CAES but uses depleted or nearly depleted hydraulically fractured wells instead of salt dome formations to store compressed natural gas that can be released to spin an expander/generator when electrical demand is high (Augustine et al., 2021b).
Compressed gas energy storage. Methods and systems for thermal energy storage and enhanced oil recovery are described herein. In some embodiments, natural gas may be injected down a well which has been previously hydraulically fractured to store thermal energy and to stimulate the well to greater hydrocarbon production.
Overview. Hazards associated with compressed gases include oxygen displacement, fires, explosions, and toxic gas exposures, as well as the physical hazards associated with high pressure systems. Special storage, use, and handling precautions are necessary in order to control these hazards.
