Compressed air energy storage (CAES) plants are largely equivalent to pumped-hydro power plants in terms of their applications. But, instead of pumping water from a lower to an upper pond during periods of excess power, in a CAES plant, ambient air or another gas is compressed and stored under pressure in an underground cavern or container.
During each discharging condition, the pressure of the compressed air decreases approximately from 4.74 to 3.27 MPa, and the amount of energy released remains steady. Therefore, the power generation capacities of the system during different cycles are relatively similar. According to Eq. (48), the ED is almost constant.
