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] 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.
[pdf] Recently, PowerChina and Shanghai Giant Energy Technology Co., Ltd. formally signed the "100MW Advanced Compressed Air Energy Storage EPC General Contract Contract", and officially won the bid for the world's first air compressed energy storage project.
