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.
Fracture initiation and propagation in the lined underground caverns for compressed air energy storage
Compressed air energy storage (CAES) has been increasingly investigated compared with conventional large-scale energy storage techniques (Zhou et al., 2017, Kim et al., 2016). This technique uses excess electric energy to store compressed air and generate electricity when needed, which is an effective way to

The hydrostatically compensated air cavern provides dry air at a quasi-constant pressure level and approximately constant temperature. We adapt our cavern model parameters to match the volume of 250 000 m 3 and the cavern depth to be 600 m. Thus, the cavern pressure equates to about 60 bar.The cavern exit temperature is given
