Compressed-air energy storage
OverviewTypesCompressors and expandersStorageHistoryProjectsStorage thermodynamicsVehicle applications
Compression of air creates heat; the air is warmer after compression. Expansion removes heat. If no extra heat is added, the air will be much colder after expansion. If the heat generated during compression can be stored and used during expansion, then the efficiency of the storage improves considerably. There are several ways in which a CAES system can deal with heat. Air storage can be adiabatic, diabatic, isothermal, or near-isothermal.

6 FAQs about [Air energy storage plant operation]
Where can compressed air energy be stored?
The number of sites available for compressed air energy storage is higher compared to those of pumped hydro [, ]. Porous rocks and cavern reservoirs are also ideal storage sites for CAES. Gas storage locations are capable of being used as sites for storage of compressed air .
What is compressed air energy storage?
Overview of compressed air energy storage Compressed air energy storage (CAES) is the use of compressed air to store energy for use at a later time when required , , , , . Excess energy generated from renewable energy sources when demand is low can be stored with the application of this technology.
What is a compressed air energy storage expansion machine?
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.
How many kW can a compressed air energy storage system produce?
CAES systems are categorised into large-scale compressed air energy storage systems and small-scale CAES. The large-scale is capable of producing more than 100MW, while the small-scale only produce less than 10 kW . The small-scale produces energy between 10 kW - 100MW .
What are the stages of a compressed air energy storage system?
There are several compression and expansion stages: from the charging, to the discharging phases of the storage system. Research has shown that isentropic efficiency for compressors as well as expanders are key determinants of the overall characteristics and efficiency of compressed air energy storage systems .
Is China planning to use compressed air for energy storage?
But according to Asia Times, China is planning to lean heavily on compressed air energy storage (CAES) as well, to handle nearly a quarter of all the country's energy storage by 2030.
