About Mine Storage (the company):
Mine Storage is an energy storage company committed to a vision of enabling a sustainable energy
transition. The idea for large-scale, fast-responding storage sprung out of the increasing share of
intermittent power generation, which causes imbalance in and significantly weakens the transmission
grids. The Mine Storage team will contribute to a sustainable future with fossil free energy production
by developing environmentally friendly energy storage facilities in decommissioned underground
mines.
About mine storage (the technology):
Mine storage is the underground version of pumped storage hydropower. It relies on the same basic
principle (moving water between two reservoirs), can store large quantities of energy and is highly
suitable to support the grid. The main difference is that the technology is applied in abandoned
industrial mining areas. This is more flexible than traditional pumped storage hydropower since there
are an estimated 1 million decommissioned mines across the globe. By using state of the art
hydropower technology that responds quickly enough to help balance the grid, mine storage can be a
true enabler for the green transition.
