Overview and Analysis for Compressed Air in Energy Storage
Partha Sarathy. Compressed Air Energy Storage (CAES) Compressed air energy storage (CAES) is a way to store energy generated at one time for use at another time. At utility scale, energy generated during periods of low energy demand (off-peak) can be released to meet higher demand (peak load) periods.
