An integration of compressed air and thermochemical energy storage with SOFC and GT was proposed by Zhong et al. [134]. An optimal RTE and COE of 89.76% and 126.48 $/MWh was reported for the hybrid system, respectively. Zhang et al. [135] also achieved 17.07% overall efficiency improvement by coupling CAES to SOFC, GT, and ORC hybrid system.
The potential energy of compressed air represents a multi-application source of power. Historically employed to drive certain manufacturing or transportation systems, it became a source of vehicle propulsion in the late 19th century. During the second half of the 20th century, significant efforts were directed towards harnessing pressurized air for the storage of …

(CAES) plants requires underground reservoirs capable of storing compressed air. In general, suitable reservoirs for CAES applications are either porous rock reservoirs or cavern reservoirs.
Compressed Air Energy Storage. Another way to store large amounts of energy is by pumping compressed air into underground caverns. In most cases, the cavern is in an underground salt deposit that can be made reasonably airtight to allow the compressed air to be stored. The salt domes used for this kind of storage are uncommon, so their ...

using underground caverns as compressed air reservoir. The energy storage capacity of the compressed air energy storage system using closed underground mines as compressed air reservoir is given by Eq. (2). E CAES=[(ṁ a+ṁ F) ∙(h 3-h 4)∙ 𝜂∙𝑡] ∙𝛼 (2) where E CAES is the stored energy (MWh per cycle), ṁ
With the development of the compressor, expander and underground energy storage facility, compressed air energy storage has been developing rapidly in recent years, and its wide application depends mostly on the cost of energy storage facility [8, [15], [16], [17]]. Thus, the key to compressed air energy storage is to find out the appropriate ...
