Simple, clever and durable: The technical concept of Gravity Storage uses the gravitational power of a huge mass of rock. It will store electricity of large capacity between 0,5 and 10 GWh and will close the gap between renewable energy production and 24/7 supply with zero carbon electricity: cost-efficient, at giga-scale, environmentally friendly.

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 ...
