Compressed air energy storage technology (CAES) is an energy storage technology that cleverly converts electrical energy into air internal energy and realizes storage and release.
Before or during this expansion, the air must be heated to prevent it from cooling to sub-zero temperatures and to improve the efficiency of the conversion. Adiabatic CAES systems use the

In the air liquefaction process, the ambient air is firstly purified to remove CO 2 and water; then, it is compressed to a high pressure by consuming offpeak electricity or renewable energy, and
To address the challenge, one of the options is to detach the power generation from consumption via energy storage. The intention of this paper is to give an overview of the current technology developments in
As renewable energy production is intermittent, its application creates uncertainty in the level of supply. As a result, integrating an energy storage system (ESS) into renewable energy systems could be
The reverse operation of both components to each other determines their design when integrated on a compressed air energy storage system. The screw and scroll are two examples of expanders, classified under reciprocating and rotary types.
A detailed understanding of compressed air energy storage systems paired with an in-depth comprehension of various expansion stages of air will form the basis for any selection criteria. The overall process of expansion is also crucial, so is fixing the operating pressure conditions as well as temperatures and flow rates.
The 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.
Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.
For the advanced adiabatic compressed air energy storage system depicted in Fig. 11, compression of air is done at a pressure of 2.4 bars, followed by rapid cooling. There is considerable waste of heat caused by the exergy of the compressed air. This occurs due to two factors.
The presence of water in compressed air energy storage systems improves the efficiency of the system, hence the reason for water vapour being injected into the system [, ]. This water vapour undergoes condensation during cooling in the heat exchangers or the thermal energy system [, ].
