Abandoned mines used as energy storage power stations

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.

How can abandoned mine facilities be used to generate energy?

Finally, a CAES plant could be established, using the upper mine galleries for underground air storage; the fact that Lieres is a “dry mine” is ideal for this type of system. Thus, the abandoned mine facilities are efficiently used to generate both electrical and thermal renewable energy. Fig. 5.

Can abandoned mines be used as reservoirs for PSPPs?

The use of abandoned mines underground spaces and currently operating mines as reservoirs for PSPPs offers an alternative solution for storing and managing surplus electricity. In 1901, Fessenden proposed the idea of storing natural interstitial energy, for instance, solar energy and wind energy.

Are pumped storage and abandoned mines a good investment in China?

A detailed review of China's latest developments in PSPPs is provided. The combination of pumped storage and abandoned mine demonstrates considerable social and environmental economic benefits. A case study of Panyi mine for developing PSAM in China are presented.

Should closed mines be used for energy storage and geothermal energy plants?

The use of closed mines for the implementation of underground energy storage plants and geothermal energy plants has important environment benefits, but usually higher operation and maintenance costs (O&M) compared to conventional systems.

What is an underground closed mine?

An underground closed mine can be used to store energy for re-use and also for geothermal energy generation, providing competitive renewable energy with a low CO2 footprint. These initiatives aid to ensure sustainable economic development of communities after mine closure. 1. Introduction
