About us

The concept of Gravity Storage was invented by Professor Eduard Heindl and has since 2014 been continually developed by the German company Heindl Energy GmbH, supported by a team of civil engineering, geology, mining and geophysics specialists.

The assets of Heindl Energy GmbH has been sold in 2021 to Gravity Storage GmbH, based in Hamburg (Germany) and funded by Dr. Sven Bode. He and the former team are now looking worldwide for a new strategic investor eager to continue the development with the goal of constructing a pilot project to bring this concept to market.

The team is looking forward to providing full support for a breakthrough of this large-scale gravity-based storage technology.

Sven Bode

Dr. Sven Bode, investor and owner of Gravity Storage GmbH. Sven followed the idea of Gravity Storage since 2013 when Robert told him about. He is a very successful founder of several companies, and his professional home is the energy market.
After his degree in industrial engineering at Technical University Hamburg-Harburg on hydrogen fueled aircrafts, he worked as a research assistant at the Hamburg Institute of Economics (HWWA) in the area of energy and climate policy. He also worked for the Hamburgische-Electricitäts Werke (later part of Vattenfall) for 3 years in department energy concept future. He holds a PhD in economics of Hamburg University (you can find a list of publications and projects here). In 2007 he founded his first start-up greenmiles, which offers specific advisory on how to make companies carbon neutral. 2010 he founded the legal-tech company flightright, which is the market leader in the field of air passenger rights enforcement in Europe and which was sold in 2019 to a large investor. Meanwhile he founded several legal-tech Start-ups.


Eduard Heindl

Prof. Dr. Dipl. Ing. Eduard Heindl is the inventor and mastermind of Gravity Storage and former Managing Director of Heindl Energy GmbH and was Member of Board of Gravity Storage Inc..

He holds a degree in physicist (University of Tübingen) and engineering and is currently Professor for IT and E-Business at University of Furtwangen, Germany. His PhD focused on early attempts of artificial intelligence. After some practical years at Siemens, he stayed since then in science and teaching.

Gravity Storage is his invention with highest impact among his track record of successful start-ups: Solarserver GmbH; A3M Technologies; Heindl Internet AG. For his ideas, like inventing a machine to create artificial glaciers or programming a warning system for tsunamis, he has been awarded several times.

Robert Werner

Robert Werner, Co-founder and former Managing Director of Heindl Energy and former CEO of Gravity Storage Inc, Chicago. Eduard and Robert met when Eduard introduced the Gravity Storage to the German Energy community for the first time in 2012.

Before, as a CEO he established a full-service utility based on renewables from start-up to EUR 90 mn annual revenue. He has intensive knowledge of the power market and of the business of planning and constructing and financing wind-, hydro- and solar power plants (investments totaling over EUR 150 mn). He is founder and CEO of the HAMBURG INSTITUT, a consulting firm for energy transition. As General Manager of Gravity Storage GmbH he coordinates the company´s current activities.

Osama Al-Olabi

In 2016, Osama introduced Gravity Storage to the Kingdom of Saudi-Arabia where it received a lot of attention and engineering assessment. His contribution to this project is his in-depth knowledge of international construction, his valuable experience and an advanced degree from Oxford University in mega project management. Further, his network to the Middle East market is extensive.
