Gravity-based storage for distributed solar – pv
The formula for gravitational potential energy in kwh is mgh/3600000. So for 1kWh of storage and a 10m elevation (about 2 stories) you''d need a 40 tonne mass.
Gravity Storage
The outstanding advantage of Gravity Storage compared to other storage technologies is its huge storage capacity. It increases with the fourth power of the piston´s radius, r4, which allows capacities up to 10 GWh or even more. The construction costs however only increase with the square of the radius, r². This means that with a wider radius
