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.

What are sustainable post-mining solutions?

Innovative technologies for sustainable post-mining solutions include the geothermal use of mine water and the pumped energy storage using the mine infrastructure, taking advantage of the deep mine shafts and voids, and the pumping installations. Worldwide, the estimate of the number of abandoned mines exceeds one million .

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

What are closed mines used for?

Closed mines can be used for underground energy storage and geothermal generation. Underground closed mines can be used as lower water reservoir for UPHES. CAES systems store energy in the form of compressed air in an underground reservoir. The geothermal use of water from a mine allows heating and cooling nearby buildings.

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.

Are mining companies balancing the need for a reliable power supply?

At the same time, mining companies are balancing the need for a reliable and stable power supply to maintain productivity and reduce downtime. In the interview below, Juergen Zimmermann, Head of Business Development and Technology at Hitachi Energy, outlines some of the key challenges and opportunities facing the mining industry.
