Green Gravity partners for mineshaft energy storage


Gravity energy storage system developer Green Gravity and underground mining contractor RUC have executed a Memorandum of Understanding (MoU) to collaborate on the commercialisation of gravitational energy storage systems.

The MoU sets out cooperation on technical opportunities, data insights and commercial arrangements.

The partnership brings together RUC’s deep capability in shaft sinking and mineshaft hoisting operations with Green Gravity’s energy storage technology.

Founder and CEO of Green Gravity Mark Swinnerton said: “Green Gravity is bringing new technology to an existing population of mineshafts.

“Partnering with a leading organisation who sunk many of those shafts is an obvious choice.

“Bringing the experience of RUC to the table allows the best knowledge of existing operations
to be included into our cutting-edge renewable energy technology.”

Swinnerton said the combination of skills of he two companies had the potential to significantly accelerate and to improve the deployment of gravitational energy storage systems into mineshafts.

“With detailed design underway for our commercial-scale energy storage system, integrating the global scale and innovative thinking of RUC to areas like the vertical transit system and mine winder design will generate superior outcomes for the technology.

“RUC is a recognised industry leader and Green Gravity is proud to be working with them.”

Green Gravity recently constructed its Gravity Lab test rig in Port Kembla NSW.

Associate Director Shafts and Underground Construction at RUC Sean Henley said: “This collaboration is a perfect fit and a great opportunity to provide our specialist expertise and help contribute to a greener future.”
