Pressure response of large-scale compressed air energy storage …
The results show that the induced pressure changes laterally throughout the storage formation are due to initial fill of the air storage. Because of high air compressibility, the pressure fluctuations caused by daily cyclic operation can only be observed in the gas phase which reaches a distance of roughly 500 m.
