Technology Description

Compressed Air Energy Storage (CAES) uses compressors to store pressurized air during low electricity demand periods and release it through turbines to generate electricity during high electricity demand periods. CAES projects typically use underground salt domes for air storage, which limits suitable geographical locations. This novel technology aims to expand the geographical locations for CAES and lower its costs by repurposing depleted hydraulically fractured gas wells for air storage.
