From abandoned mine to pump storage station
In a world first, they''ve turned a flooded abandoned mine pit at Kidston into a system that uses solar energy to pump water out of the mine pit during the day to provide power for the nearby town at night. Mott MacDonald''s Ashley Grohn told me how it works. Ashley - The Kidston project converts a 100 year old gold mine and repurposes
Energy from closed mines: Underground energy storage
Energy storage systems are required to increase the share of renewable energy. 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.
