The complex liquid cooling circuit increases the danger of leakage, so the liquid cooling system (LCS) needs to meet more stringent sealing requirements [99]. The focus of the LCS research
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.
Liquids for the cold/heat storage of LAES are very popular these years, as the designed temperature or transferred energy can be easily achieved by adjusting the flow rate of liquids, and liquids for energy storage can avoid the exergy destruction inside the rocks.
In this context, liquid air energy storage (LAES) has recently emerged as feasible solution to provide 10-100s MW power output and a storage capacity of GWhs.
A liquid cooled system is generally used in cases were large heat loads or high power densities need to be dissipated and air would require a very large flow rate. Water is one of the best heat transfer fluids due to its specific heat at typical temperatures for electronics cooling.
The heat engine-based systems that incorporate thermal storage with thermodynamic cycles for power/heat generation are covered in Chapters 3 and 636, including compressed air energy storage, liquid air energy storage, and pumped heat energy storage.
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.
