What is compressed air energy storage?

Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.

How to reuse temperature related exergy of compressed air?

The simplest way to reuse the temperature related part of the exergy of the compressed air is to store the hot air itself inside a combined thermal energy and compressed air storage volume (Fig. 18a). Due to the high temperatures already reached at rather low pressure ratios these concepts require highly temperature resistant storage volumes.

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.
