Concluding remarks Liquid Air Energy Storage systems have the potential to be a competitive local and grid scale energy storage technology. They also have the potential to facilitate the penetration of renewable energy technologies.
4.1. Standalone liquid air energy storage In the standalone LAES system, the input is only the excess electricity, whereas the output can be the supplied electricity along with the heating or cooling output.
2.1. History 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 .
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.
The basic principle of LAES involves liquefying and storing air to be utilized later for electricity generation. Although the liquefaction of air has been studied for many years, the concept of using LAES “cryogenics” as an energy storage method was initially proposed in 1977 and has recently gained renewed attention.
