Are lined rock caverns a good choice for compressed air energy storage?
Some new conceptual conclusions about lined rock caverns in compressed air energy storage systems are proposed. Compressed air energy storage (CAES) is considered as a feasible approach of providing ancillary services to the power system, with the underground lined rock cavern (LRC) being a good choice for storing compressed air.
What is the maximum compressed air pressure in a rock cavern?
The rock cavern is in granite and has good rock mass quality. The maximum compressed air pressure is 10 MPa. The cavern stability in the excavation and operation stages needs to be evaluated.
How does cyclic loading affect the stability of a rock cavern?
A rock mass is mainly subjected to a high internal pressure load in the lined rock cavern (LRC) for compressed air energy storage (CAES). However, under the action of long-term cyclic loading and unloading, the mechanical properties of a rock mass will deteriorate, affecting the long-term stability of the cavern.
Do lined rock caverns have high internal pressure?
The mechanical response of the lined rock caverns with high internal pressure is theoretically analyzed. Some previously conceptual conclusions about lined rock caverns in compressed air energy storage systems are identified. The sensitive parameters about the building of lined rock caverns in compressed air energy storage systems are given.
How stable is a CAES underground rock cavern?
The CAES underground rock cavern is subjected to both the internal cyclic air pressure and the external rock pressure from the surrounding rock, thus its stability over the CAES operation is of great significance and should be investigated in detail (Xia et al., , Xu et al., ).
