The basic idea of diabatic CAES was to transfer off-peak energy produced by base nuclear or coal-fired units for high-demand periods, using only a fraction of the gas or oil that would be used by a standard peaking machine, such as a conventional gas turbine. No experience has been gained to date in the use of abandoned mines for
Potential of repurposing abandoned coal mines, as lower reservoirs for UPSPs. For example, numerous studies on compressed air energy storage (CAES) in salt caverns have shown that rapid temperature drops can cause local mechanical instabilities in the form of spalling and tensile fractures on the cavern wall [193, 194].
Abandoned coal mines have many underground space resources, such as roadways, shafts, and gobs. Among them, abandoned roadways are the best gas storage space for underground compressed air energy

Operationally, abandoned coal mines may safely store compressed air if the shafts and drifts are completely sealed from remaining coal seams to mitigate risks of tunnel wall leaks and
At present, the underground gas storages that can be used for large-scale compressed air energy storage mainly include underground salt caverns [7][8][9], hard rock caverns [10][11][12], abandoned
Compressed air energy storage (CAES) is an established and evolving technology for providing large-scale, long-term electricity storage that can aid electrical power systems achieve the goal of decarbonisation. CAES facilities often utilise large underground storage caverns to ensure high capacity systems. This results in the need
Renewable energy (wind and solar power, etc.) are developing rapidly around the world. However, compared to traditional power (coal or hydro), renewable energy has the drawbacks of intermittence and instability. Energy storage is the key to solving the above problems. The present study focuses on the compressed air energy

Underground coal mines can be used as a lower reservoir of a UPSH project plant. • UPSH allows storing and producing large amounts of energy in abandoned mines from the depressed mining regions. • The water is stored in a reservoir in the form of a network of tunnels. • A numerical model has been made to analyze the behavior of the
Compressed Air Energy Storage (CAES) Compressed air energy storage (CAES) is a way to store energy generated at one time for use at another time. At utility scale, energy generated during periods of low energy demand (off-peak) can be released to meet higher demand (peak load) periods.
Thus, abandoned oil/gas wells and coal mines can provide ample reservoir volume and appropriate stability for compressed air energy. Regarding cost, the capital costs of compressed air energy storage
In this paper,the reuse of abandoned roadway in coal mine as the compressed air storage of compressed air energy storage( CAES) power station was studied. And taking Xuzhou Quantai coal mine as an example,a study on CAES is made. The results show that combining abandoned roadway in coal mine,CAES technology and the price difference

Underground space from abandoned mines can be used as underground reservoirs for underground pumped storage hydropower (UPSH) and compressed air energy storage (CAES) systems [5–11]. Pumped storage hydropower (PSH) is the most mature large-scale energy storage technology,
Turning abandoned mines into energy storage is one example of many solutions that exist around us, and we only need to change the way we deploy them," study co-author Behnam Zakeri said. A novel
However, the effects of EDZ on the stability of the CAES cavern from the roadways of abandoned coal mines have not been investigated.

An abandoned coal mine after long-term service may have a much larger damage zone than those in hard rock caverns and salt caverns [29]. The damage zone may be heterogeneous with different partitions. This numerical simulation model for the compressed air energy storage in abandoned mines is verified by the simulation
Even after the abandoned coal mines are closed, a large quantity of underground resources remains undeveloped and unutilized. According to the survey, coal mines that have been closed so far contain coal resources of up to 42 billion tons, while the natural gas resources are estimated to be nearly 500 billion m 3.Moreover, there also
