Compressed Air Energy Storage (CAES) has the potential to meet critical grid needs for affordability, reliability, and long-duration energy storage. CAES features paired compression and expansion systems connected by an air storage reservoir. During off-peak hours, excess energy from the grid is used to compress air via a compression train and stored in a solution-mined salt cavern. Then, during peak hours, the stored air is released, reheated and expanded through the...
