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. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational as of 2024.
Liquid air energy storage (LAES), as a form of Carnot battery, encompasses components such as pumps, compressors, expanders, turbines, and heat exchangers [7] s primary function lies in facilitating large-scale energy storage by converting electrical energy into heat during charging and subsequently retrieving it during discharging [8].Currently, the …

The energy storage systems encompasses technologies that separate the generation and consumption of electricity, allowing for the adaptable storage of energy for future utilization [4].Currently, pumped hydro energy storage holds the majority share of global installed capacity for ESS, owing to its well-established technology, high round trip efficiency (RTE), and quick …
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 distributioncenters. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.
The potential energy of compressed air represents a multi-application source of power. Historically employed to drive certain manufacturing or transportation systems, it became a source of vehicle propulsion in the late 19th century. During the second half of the 20th century, significant efforts were directed towards harnessing pressurized air for the storage of electrical …

Upon removal from storage, the temperature of this compressed air is the one indicator of the amount of stored energy that remains in this air. Consequently, if the air temperature is too low for the energy recovery process, then the air must be substantially re-heated prior to expansion in the turbine to power a generator.
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 [, ].
