This paper surveys state-of-the-art technologies of CAES, and makes endeavors to demonstrate the fundamental principles, classifications and operation modes of CAES.
What is the typical pressure used in compressed air energy storage?
During the operation, excess electricity is used to compress the air into a salt cavern located underground, typically at depths of 500–800 m and under pressures of up to 100 bars. Diabatic storage systems utilize most of the heat using compression with intercoolers in an energy storage system underground.
How is energy stored in a low demand space?
In low demand periods, energy is stored by compressing air in an air tight space (typically 4.0~8.0 MPa) such as an underground storage cavern. To store energy, air is compressed and sealed in the space. To extract the stored energy, compressed air is drawn from the storage vessel, mixed with fuel, and then combusted. The expanded air is then passed through a turbine.
