efficiency of compressed air energy storage in caves

ABSTRACT: Compressed Air Energy Storage (CAES) in caverns is gaining prominence for its role in ensuring grid stability by storing surplus energy and releasing it as needed, thus addressing the intermittent nature of renewable energy sources. However, existing research on CAES caverns stability

Motivated by the suboptimal performances observed in existing compressed air energy storage (CAES) systems, this work focuses on the efficiency optimization of CAES through thermal energy storage (TES) integration. The research explores the dependence of CAES performance on power plant layout

In compressed air energy storages (CAES), electricity is used to compress air to high pressure and store it in a cavern or pressure vessel. During compression, the air is cooled to improve the efficiency of the process and, in case of underground storage, to reach temperatures comparable to the
