Radically accelerating the world''s renewable transition
Green Gravity’s energy storage system moves heavy weights vertically in legacy mine shafts to capture and release the gravitational potential energy of the weights. By simply using proven mechanical parts and disused mine shafts, Green Gravity’s energy storage technology is low-cost, long life and environmentally compelling.
Storing energy in this way uses no processed chemicals and has no performance degradation. Moving weights vertically allows for high Round Trip Efficiency and using legacy mine shafts allows reuse of existing structures, contributing to the circular economy and lowering costs.
Green Gravity''s energy storage technology improves the economics of wind and solar power, leading to a faster and lower cost transition away from fossil fuels. Truly the next generation of ultra-green energy.
Green Gravity''s energy storage solution harnesses the fundamental principles of gravity and kinetic energy to store and dispatch energy by lifting and lowering heavy-weighted objects. Green Gravity’s innovative technology was inspired by pumped hydro like Snowy 2.0.
Like pumped hydro, we use the gravitational potential energy of a mass moving between two heights. However, rather than water between two dams, Green Gravity requires much less space by using very dense materials. To overcome friction, a vertical height available from a mine shaft is used rather than an incline on the side of a hill.
Our solution can provide services at all levels of the electricity system. We make renewable energy cheaper, make the grid more stable and reduce transmission costs, and can help mines and industrial plants reduce carbon emissions. We also have a role in supporting local community energy schemes through firming distributed energy resources.

Gravitational storage refers to a process of converting electrical energy into gravitational potential energy through moving an object to a height. The energy is then released back to electrical energy at a later time by moving the object to a lower height, in the process turning an electric motor using the kinetic force of the descending object.
Green Gravity’s system can be deployed in many types of mine shafts. With nearly 100,000 shafts in Australia, this offers many potential deployment locations. Locations with the best economic case include those with shafts built after 1950, with electrical infrastructure sill accessible, and with greater depth. Shafts over 300 metres deep offer very attractive energy economics.
Green Gravity’ energy storage system is fundamentally more sustainable than chemical batteries. Some of the most important differentiating points include:
