The concern about climate change and global warming has triggered global paradigm shift and different energy industrial environment. Energy storage system (ESS) comes into the spotlight as an emerging industry.
Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distributioncenters. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator. An attractive feature of this
Underground compressed air energy storage (CAES) in lined rock caverns (LRCs) provides a promising solution for storing energy on a large scale. One of the essential issues facing underground CAES implementation is the risk of air leakage from the storage caverns. Compressed air may leak through an initial defect in the inner containment liner, such

Hydrostor, based in Toronto, Canada, has developed a new way of storing compressed air for large-scale energy storage. Instead of counting on a salt dome, the company makes a series of shafts that go several thousand feet underground, miners are then sent underground to hollow out a cavern that can be used for compressed air storage.
Large scale energy storage (LSES) systems are required in the current energy transition to facilitate the penetration of variable renewable energies in the electricity grids [1, 2].The underground space in abandoned mines can be a solution to increase the energy storage capacity with low environmental impacts [3], [4], [5].Therefore, underground pumped storage

What is the problem with compressed air energy storage? The main problem with CAES is its low energy efficiency. During compressing air, some energy is lost due to heat generated during compression, which cannot be fully recovered.

The first patent for compressed air storage in artificially constructed cavities deep underground, as a means of storing electrical energy, was issued in the United States in 1948.
Compressed air storage in underground formations is an excellent way to balance energy production and consumption. During off-peak hours, with the consumption of excess electrical energy, the air is temporarily stored at high pressure in the desired environment.
Compressed air energy storage in aquifers (CAESA) has been considered a potential large-scale energy storage technology. However, due to the lack of actual field tests, research on the underground processes is still in the stage of theoretical analysis and requires further understanding. In this study, the first kilometer depth compressed air

Energy Guides; Underground Compressed-Air Energy Storage. Intermittent renewable energy needs large-scale energy storage to become a complete energy solution that is capable of providing reliable power 24/7. And the media coverage of energy storage has focused on Tesla and its battery systems when many other -arguably more suitable solutions exist.

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
Recovering compression waste heat using latent thermal energy storage (LTES) is a promising method to enhance the round-trip efficiency of compressed air energy storage (CAES) systems.
The positive experience gained from underground storage of natural gas cannot be directly extrapolated to compressed air storages because of the risk of reactions between the oxygen in the air and the minerals and microorganisms in the reservoir rock.
In Germany, a patent for the storage of electrical energy via compressed air was issued in 1956 whereby “energy is used for the isothermal compression of air; the compressed air is stored and transmitted long distances to generate mechanical energy at remote locations by converting heat energy into mechanical energy” .
