Compressed-air-energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods.

Customer ServiceCompressed 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.

Customer ServiceThe integration of wind energy and CAES plants holds the potential to enhance the penetration of wind energy in large-scale electrical grids while facilitating the transition from diesel-fired power to a renewable energy source [23].
Customer ServiceThe performance of compressed air energy storage systems is centred round the efficiency of the compressors and expanders. It is also important to determine the losses in the system as energy transfer occurs on these components. There are several compression and expansion stages: from the charging, to the discharging phases of the storage system.
(1) explains how electrical energy can be stored as exergy of compressed air in an idealized reversed process. The Adiabatic method achieves a much higher efficiency level of up to 70%. In the adiabatic storage method, the heat, which is produced by compression, is kept and returned into the air, as it is expanded to generate power.
With an increasing capacity of wind energy globally, wind-driven Compressed Air Energy Storage (CAES) technology has gained significant momentum in recent years. However, unlike traditional CAES systems, a wind-driven CAES system operates with more frequent fluctuations due to the intermittent nature of wind power.
There is cooling of the air as it flows via the thermal energy storage device, followed by an after-cooler. From this stage, there is compression of the air until required pressure is achieved. This means that the temperature of the air is again raised to 380 °C. There is an exchange of heat in the second thermal energy storage system.
This compressed air is held at this storage pressure and then, in times of energy deficiency, this pressurised air is heated, and expands in an expansion turbine which drives a generator that helps to meet power supply demand. An example of a CAES system attached to a wind turbine is also shown below in Fig. 20.
Expansion machines are designed for various compressed air energy storage systems and operations. An efficient compressed air storage system will only be materialised when the appropriate expanders and compressors are chosen. The performance of compressed air energy storage systems is centred round the efficiency of the compressors and expanders.
