Gravity Storage

Who we are and what we do

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

Gravity Storage Inc. is the only shareholder of Heindl Energy. Gravity Storage Inc. is owned by Swiss investor HTG Ventures AG, which is financing the development of the concept. Heindl Energy holds several patents on this storage concept and is currently developing its readiness for realization, with the goal of constructing a pilot project.

Status of development

We are preparing the engineering and planning for a demonstrator plant we intend to build to proof the concept. The demonstrator will be the starting point of a stepwise market uptake and a gradual commercialization.
