Abstract. It is anticipated that utilizing the underground space in abandoned mines to build and operate pumped-storage hydroelectricity (PSH) plants can reduce capital investment and geological constraints. However, there are currently few detailed investigations into techno-economic feasibility except for conceptual studies. In this

In general, in accordance with the presence or absence of natural runoff, PSPPs are divided into two categories. One is a pure PSPP [32], where the upper reservoir has no or only a small amount of natural runoff, and the water body is recycled between two reservoirs; these PSPPs are mainly used in tasks such as peak shaving and emergency

However, not all old coal mines have suitable head heights for building pumped storage power plants. Existing studies [44, 57] have indicated that the optimal head height is between 200 m and 800
Former mines in the United Kingdom Midlands could provide 804 MWh of storage. This paper investigates the potential of using gravity energy storage with suspended weights as a new technology for redeveloping abandoned deep mine shafts. The technology has relatively low energy density, but has advantages including a power
This paper has investigated gravity energy storage using suspended weights as a new technology for redeveloping abandoned deep mine shafts. It has been shown how to size of the suspended weight to maximize the energy storage capacity for a mine shaft, given its physical dimensions. It has also been shown that faster ramp-rates

In the future, there will be more and more abandoned oil-gas wells with the exploitation of onshore oilfield resources. However, the large height difference in abandoned oil-gas wells can be used as building blocks for gravity power generation, thus maximizing the economic value of abandoned oil-gas wells. In this study, a scheme of gravity power generation
Currently, most subterranean infrastructures are abandoned without further use [29, 30], but they could be reused to promote circular economy for a current and necessary purpose.This would contribute to achieving several sustainable development goals [31] and introducing circular economy in the mining sector, given the fact that it is

Hard coal mines in Poland are very large, making them suitable for CAES technology. However, in order to apply the CAES technology in abandoned coal mines in Poland, further studies on the impact of this technology on the underground and above-ground environment are necessary. 4. Underground Gas Energy Storage.
Mine gas from abandoned mines typically contains no oxygen, and its composition changes very slowly. The methane content can range from 60-80%. Even after coal mines are shut down, coal mine gas continues to be released. The composition of abandoned mine methane gas presents no technical difficulties for combustion in gas engines.
The Quincy Mine, on Michigan''s Keweenaw Peninsula, is one more than 1,000 old hard-metal mines across the nation with the potential to add reliable energy storage to the mix, offering even more possibilities.
