The quest for carbon neutrality raises challenges in most sectors. In coal mining, overcapacity cutting is the major concern at this time, and the increase in the number of abandoned mine shafts is a pervasive issue. Pumped storage hydropower (PSH) plants built in abandoned mine shafts can convert intermittent electricity into …
An Energy Swiss Army Knife. A mine storage supports the energy system in several ways, often simultaneously. It can act as energy storage, grid frequency regulator, capacity reserve, transmission support, inertia provider, or as a behind-the-meter solution to support large energy producers or energy-intensive industries.
