Gravity Storage

The worldwide rapid construction of fluctuating renewable energy sources, such as wind and solar energy, has created an increasing demand for storing large quantities of energy. In order to sustain an uninterrupted supply of energy in a grid system dominated by renewable energy sources, there must be substantially larger storage capabilities than available today to cover long periods of little or no wind, and reduced periods of sunshine.

The concept of Gravity Storage (also known as Hydraulic Rock Storage) offers an innovative solution because it can store large amounts of energy for a long time. A cylinder of rock that has been exposed from its natural surroundings is raised up using water pressure, and when power is needed, the water is released and routed to turbines.

Heindl Energy GmbH is developing this concept with the goal of building a pilot project. Please explore our website to learn more about this exciting concept.

Heindl Energy signed a Cooperation Agreement with Al-Ayuni Investment & Contracting Company, a large multidimensional Saudi company, for joint planning, design development and construction of a Demonstrator of Gravity Storage.  

The Demonstrator would be built on one of the numerous granite quarries of Al-Ayuni in Saudi Arabia. The project will generate cheap electricity and the design will be patented and put to commercial use as a joint business with Al-Ayuni in the Gulf region.
