Abstract: An underground fluid storage structures formed by mechanical excavation of a subsurface formation in a controlled fashion. The structure comprises vertical holes (260, 270) and transversal caverns (256) of circular section and preferably in spiral arrangement. Storage caverns as described herein may further employ hydraulic pressure compensation to prevent wide pressure variations in the storage caverns, and to provide relatively constant injection and discharge pressures when introducing or releasing stored fluids. The preferred application is compressed air energy storage (CAES) systems for storing energy in the form of compressed air in order to generate electricity.
