It uses cryogen, or liquid air, as its energy vector. This study, for the first time, employed systematic, content, and bibliometric review approaches to provide an overview of the progress of research on LAES technology between 2000 and 2023.
This paper fills the gaps mentioned above and provides a comprehensive overview of LAES technology, covering its development history, comparison with other energy storage technologies, and research progress of LAES subsystems, standalone LAES systems, and hybrid LAES systems.
Although the liquefaction of air has been studied for over a century, the first concept of using cryogenics as energy storage was proposed for the first time in 1977 and rediscovered only in recent times.
Korean scientists have designed a liquid air energy storage (LAES) technology that reportedly overcomes the major limitation of LAES systems - their relatively low round-trip efficiency.
Liquid air energy storage (LAES) can offer a scalable solution for power management, with significant potential for decarbonizing electricity systems through integration with renewables.
Liquid Air Energy Storage (LAES) represents an innovative energy storage technology, leveraging air as the storage medium and the working fluid. As a promising solution to address the inherent variability of renewable energy sources, LAES enhances grid stability and resilience. LAES has attracted significant attention due to its high energy density, scalability, geographical flexibility,
Korean scientists have designed a liquid air energy storage (LAES) technology that reportedly overcomes the major limitation of LAES systems - their relatively low round-trip efficiency.
The air purification process in LAES imposes constraints on the energy storage efficiency and energy storage duration. To enhance the flexibility, continuous energy storage capability, and system efficiency, this paper proposes a
Liquid air energy storage (LAES) is becoming an attractive thermo-mechanical storage solution for decarbonization, with the advantages of no geological constraints, long lifetime (30–40 years), high energy density (120–200
A particular form of CES, Liquid Air Energy Storage (LAES), has gained growing attention respect to other cryogens. The current state of LAES is still at the development and demonstration stage since no com- mercial or pre-commercial plants have been built.

Concluding remarks Liquid air energy storage (LAES) is becoming an attractive thermo-mechanical storage solution for decarbonization, with the advantages of no geological constraints, long lifetime (30–40 years), high energy density (120–200 kWh/m 3), environment-friendly and flexible layout.
Hybrid LAES has compelling thermoeconomic benefits with extra cold/heat contribution. Liquid air energy storage (LAES) can offer a scalable solution for power management, with significant potential for decarbonizing electricity systems through integration with renewables.
2.1.1. History of liquid air energy storage plant The use of liquid air or nitrogen as an energy storage medium can be dated back to the nineteen century, but the use of such storage method for peak-shaving of power grid was first proposed by University of Newcastle upon Tyne in 1977 .
Consulting, 2012; IEC, 2011; IRENA, 2017). Air has been recently regarded as a Cryogenic Energy Storage (CES) medium, whereby air is liquefied at around −195 °C and stored in insulated tanks (Antonelli et al., 2017). This technology is called Liquid Air Energy Storage (LAES).
Liquid air does not require important storage volumes consid- ering significant energy density compared to that of PHS and CAES (Chen et al., 2009). Therefore, LAES is considered as a compact- technology.
