Radically accelerating the world’s renewable transition
Green Gravity uses disused mines to store energy. This allows renewable energy to be used when it is needed.
Our technology
Green Gravity’s technology raises and lowers heavy weights in a mine shaft to capture and release the gravitational energy of the weights.
Green Gravity partners with Wollongong Resources to study 8 sites for gravitational energy storage
Green Gravity and Wollongong Resources have signed a Memorandum of Understanding (MOU) to study the application of gravitational energy storage technology at up to 8 sites in NSW. The project has the potential to deliver more than 100 MWh of clean energy storage within the greater Sydney metropolitan area.
Buried Treasure: Startup Mines Clean Energy’s Prospects With Digital Twins
NVIDIA
Mark Swinnerton aims to fight climate change by transforming abandoned mines into storage tanks of renewable energy. The CEO of startup Green Gravity is prototyping his ambitious vision in a warehouse 60 miles south of Sydney, Australia, and simulating it in NVIDIA Omniverse, a platform for building 3D workflows and applications.

Green Gravity Concludes Partnership Aimed At Delivering Energy Storage At Seventeen Sites In Romania
Green Gravity and Complexul Energetic Valea Jiului S.A. (CEVJ) have executed a Cooperation Framework Agreement to explore the application of Green Gravity’s innovative energy storage technology in seventeen (17) mine shafts on the four (4) mining operations in the Valea Jiului in Romania.
Our technology provides low-cost, flexible and ultra-green energy storage.
Circular
Driving circular economic value by reusing old mine shafts to support green energy.
Flexible
Provides short or mid duration storage or grid ancillary services.
Sustainable
Low noise, small land use, no water, chemicals, or destruction of farmland. Our technology can be fully recycled, unlike battery options.
Local
Locally sourced materials, supply chain and workforce create economic value in the local community.
Low-Cost
Offering attractive economics due to reuse of infrastructure, high efficiency, low operating and maintenance costs and long life of the asset.
Long Life
Our system does not degrade, meaning we invest once to match long run energy security needs, avoiding the costly performance degradation of batteries.
