Investing in the future of energy storage

The concept of Gravity Storage was invented by Professor Eduard Heindl and has since then been continually developed by the company Heindl Energy GmbH, supported by a team of civil engineering, geology, mining and geophysics specialists.

Early 2020 Heindl Energy GmbH ran out of cash and filed for insolvency. The patents and the engineering work has been sold to an interim investor, Gravity Storage GmbH, who is now looking for a new strategic investor willing to continue the development.

Gravity Storage

Gravity Storage is a concept with which unprecedentedly large quantities of power can be stored for a long time of 6-14 hours, and can be made available again. The fundamental principle is based on the hydraulic lifting of a large rock mass. Using electrical pumps, as already used today in pumped storage power plants, water is pumped beneath a movable rock piston, thereby lifting the rock mass. During times of insufficient generation of renewable power, the water which is under high pressure from the rock mass, is routed to a turbine, as in conventional hydroelectric plants, and generates electricity using a generator.

The capacity of energy storage can be choosen between 1 and 10 GWh, comparable to large Pumped Hydro Storage. For more information see also:
