For example, replanting abandoned leases could earn carbon credits under the Australian government''s Carbon Farming Initiative. It can help ''hard to abate'' industries such as mining move towards net zero emissions. Sustainable and renewable energy: Abandoned mines can also be used to produce and store renewable energy.
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

Generate PDF. Abandoned coal mines contain large volumes of water at constant temperatures (increasing with depth by 1-3 °C per 100 m), thanks to their networks of flooded galleries and shafts lying at depths of up to several hundred metres below the surface.
