An alternative to those systems is represented by the liquid air energy storage (LAES) system that uses liquid air as the storage medium. LAES is based on the concept that air at ambient pressure can be liquefied at −196 °C, reducing thus its specific volume of around 700 times, and can be stored in unpressurized vessels.
The liquid air storage section and the liquid air release section showed an exergy efficiency of 94.2% and 61.1%, respectively. In the system proposed, part of the cold energy released from the LNG was still wasted to the environment.
When air is liquefied, it is usually separated into its components, mainly liquid nitrogen and liquid oxygen that finds a wide range of industrial and medical applications. From the beginning of the 20th century, there were several attempts to use cryogenic media as an alternative energy vector mainly for transports .
The storage section of the LAES stores the liquid air produced by the liquefaction cycle in unpressurized or low pressurized insulated vessels. The energy losses for a LAES storage tank can be estimated to be around 0.1–0.2% of the tank energy capacity per day, which makes the LAES suitable as a long-term energy storage system.
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 .
LAES uses electricity to cool air below -196 degrees Celsius, turning it into a liquid. This liquid air is stored in insulated tanks until it is needed. Excess renewable energy is converted into electricity. Electricity is utilized to liquefy air. Liquid air is stored in insulated tanks until energy demand arises.
