Compressed air energy storage (CAES) is one of two available grid-scale energy storage systems [11]. CAES is superior to pumped hydro energy storage (PHES) because of its relatively longer life time, much lower environmental impact, shorter construction time, higher reliability and lower installation costs [12] .
Compressed air energy storage (CAES) is a large-scale energy storage technology that can overcome the intermittency and volatility of renewable energy sources, such as solar
Regarding cost, the capital costs of compressed air energy storage are generally driven by the storage vessel itself. Thus, replacing a fabricated storage vessel with an abandoned well or mine can have large benefits to the cost.

Many studies on the use of abandoned mines for energy storage are described in the literature. For example, they refer to thermal energy storage [13,14], compressed air energy storage [15][16]
Compressed air energy storage (CAES) is a large-scale energy storage technology that can overcome the intermittency and volatility of renewable energy sources, such as solar and wind energy. Although abandoned mines can be reused for
Compressed-air energy storage can also be employed on a smaller scale, such as exploited by air cars and air-driven locomotives, and can use high-strength (e.g., carbon-fiber) air-storage tanks. In order to retain the
Therefore, Underground Pumped Storage Power Plants (UPSP), as first introduced in the early 20th century by Fessenden [11], offer a viable solution that capitalizes on the utilization of abandoned underground spaces and effectively circumvents topographical constraints and limitations associated with surface footprint [5, 12].
