[pdf] Compression of air creates heat; the air is warmer after compression. Expansion removes heat. If no extra heat is added, the air will be much colder after expansion. If the heat generated during compression can be stored and used during expansion, then the efficiency of the storage improves considerably. There are several ways in which a CAES system can deal with heat. Air storage can be , diabatic, , or near-isothermal.

[pdf] Chinese energy storage specialist Guangdong Yuyang New Energy leveraged its self-developed air-cooled energy storage system to establish strategic cooperation with African partners, culminating in the successful delivery of a 300kW-1MWh project (using 20-foot standard containers) in July 2025.
[pdf] Some of the challenges of this technology include high upfront capital costs, the need for heat during the expansion step, lower round-trip efficiency (RTE), siting and permitting challenges, difficulty in identifying and preparing natural caverns for storage, low depth of discharge, and longer response times.
