Abstract

It is trite to say that energy storage is essential for furthering renewable energy by stabilizing the supply and demand. It is also cliché to point out that compressed air energy storage (CAES) is a promising means for energy storage. To highlight but a few of the multitude of recent publications on CAES, Tan et al. [1] present a comprehensive review concerning various energy storage technologies for empowering smart grid. CAES is also one of the most promising energy storage means in the harsh marine environment [2]. Guo et al. [3] discuss the promise and challenges of utility-scale CAES in aquifers. A regional review of CAES for northern China is compiled by Tong et al. [4]. Mahmoud et al. [5] compare and contrast the three main mechanical energy storage options, flywheel, pumped hydro, and CAES. They conclude that flywheel is best suited for short-duration applications. For longer durations, pumped hydro has the efficiency while CAES provides a faster start-up. For good environmental stewardship, adiabatic or isothermal CAES is recommended. In short, the case for CAES is clear. It is expected to ramp up its importance as we march forward to harness progressively greener energy.
