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.
Australian startup to fast-track gravity energy storage system
Green Gravity covered in pv Magazine Australia with excellent insights into the impact of partnership with GHD and with Yancoal Australia Ltd to the rapid commercialisation of clean tech.
Green Gravity Partners With GHD To Strengthen Technology Commercialisation
Green Gravity and global professional services company GHD have executed a Memorandum of Understanding (MoU) to collaborate on the commercialisation of gravitational energy storage systems.
Gravity could soon put power back into Austar mine at Cessnock
Regional radio station 2HD published an article on the positive impact Green Gravity’s storage can have on legacy mining sights and the MOU between Green Gravity and Yancoal.
Green Gravity collaborates with Yancoal to conduct gravitational energy storage technology study at former Austar Coal Mine site near Cessnock
Local publication, Cessnock Advertiser, looks into the economic prospects that Green Gravity can offer regional communities with debilitated mining infrastructure, such as Yancoal’s Austar mine in Cessnock.
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.
