OverviewTypesCompressors and expandersStorageEnvironmental ImpactHistoryProjectsStorage thermodynamics
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.
Recent research on new energy storage types as well as important advances and developments in energy storage, are also included throughout.
The investigation thoroughly evaluates the various types of compressed air energy storage systems, along with the advantages and disadvantages of each type. Different expanders ideal for various different compressed air energy storage systems are also analysed.

Isochoric as well as isobaric compressed air storage systems are ideal for both underground or above storage systems. The compressed air storages built above the ground are designed from steel. These types of storage systems can be installed everywhere, and they also tend to produce a higher energy density.
Modularity of compressed air energy storage systems is another key issue that needs further investigation in other to make them ideal for various applications.

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.
There are several options for underground compressed air energy storage systems. A cavity underground, capable of sustaining the required pressure as well as being airtight can be utilised for this energy storage application. Mine shafts as well as gas fields are common examples of underground cavities ideal for this energy storage system.
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.
There are several compression and expansion stages: from the charging, to the discharging phases of the storage system.
