underground gravity energy storage

Gravity energy storage

Underground gravitational energy storage The idea of this system, also known as gravitricity, is the use of mine shafts that are already existing and in service. The use of a very deep vertical pathway (a hole into the ground) to carry a big mass (in the shape of a shaft) is the main principle of this GES concept for charging and discharging ...
