ABSTRACT Compressed air energy storage (CAES) is considered a viable option for matching intermittent sustainable energy and the production of peak electrical demand.
The present study focuses on the compressed air energy storage (CAES) system, which is one of the large-scale energy storage methods. As a lot of underground coal mines are going to be closed in China in the coming years, a novel CAES system is proposed for application in roadways of the closing coal mines.
Compressed air energy storage (CAES) in underground mine tunnels using the technique of lined rock cavern (LRC) provides a promising solution to large-scale energy storage. A coupled thermodynamic and thermomechanical modelling for CAES in mine tunnels was implemented. Thermodynamic analysis of air during CAES operation was carried out.

The results are given in Table 2. It can be seen that the pressure loss in the water pipe is approximately 0.11 MPa, while that in the air pipe is 1.19 MPa.
Brief Introduction of a Compressed Air Energy Storage System A typical CAES system without heat storage has three parts, as seen in Figure 2 a, i.e., air compressing (electromotor and compressor), air storage, and the power-generating unit (turbine and generator).
Among the different ES technologies, compressed air energy storage (CAES) can store tens to hundreds of MW of power capacity for long-term applications and utility-scale. The increasing need for large-scale ES has led to the rising interest and development of CAES projects.
