Energy storage measures in abandoned tunnels of coal mines

Can underground space energy storage technology be used in abandoned coal mines?

The underground space resources of abandoned coal mines in China are quite abundant, and the research and development of underground space energy storage technology in coal mines have many benefits.

Can abandoned mines be used for energy storage?

Closed mines can be used for the implementation of plants of energy generation with low environmental impact. This paper explores the use of abandoned mines for Underground Pumped Hydroelectric Energy Storage (UPHES), Compressed Air Energy Storage (CAES) plants and geothermal applications.

Can abandoned coal mine facilities be used to generate energy?

Thus, the abandoned mine facilities are efficiently used to generate both electrical and thermal renewable energy. Fig. 5. Combined design of underground energy storage systems (UPHES and CAES) and geothermal utilization in an abandoned underground coal mine.

What are underground energy storage and geothermal applications?

Underground energy storage and geothermal applications are applicable to closed underground mines. Usually, UPHES and geothermal applications are proposed at closed coal mines, and CAES plants also are analyzed in abandoned salt mines. Geothermal power plants require flooded mines, which generally have closed more than 5 years ago.

What is coal underground thermal energy storage?

Coal underground thermal energy storage (CUTES) is a form of energy storage that makes extensive use of the underground highways in closed mines as a place to store energy and to offer heating and cooling in the winter and summer months, respectively.

Can a mine thermal energy storage system be used in abandoned mines?

Out of this reason, fundamental research in the eld of seasonal heat storage in abandoned mines has to be conducted for further technology develop-ment and establishment of large scale storage systems. e aim of this feasibility study is to conceptualize a mine thermal energy storage system for the hard coal mine Prosper-Haniel.
