Thermodynamic study on the effect of cold and heat recovery on performance of liquid air energy storage …
Our analyses found that the amount of cold energy recovered in the discharging cycle is not enough to fully cool the compressed air in the charging cycle (see details in Section 3.1.3), whereas the compression heat generated in the charging cycle is in excess and cannot be used efficiently in the discharging cycle (see details in Section 3.1.4).

Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season. For example, heat from solar collectors or waste heat from air conditioning equipment can be gathered in hot months for space heating use when needed, including during winter months. …
