Green Gravity has secured a lease to conduct its first underground trial of gravity energy storage technology at the #4 shaft of the Russell Vale coal mine near Wollongong. The project involves installing safety equipment and repurposing old mine infrastructure to test a system that stores 150 kW of power using a 400-meter deep shaft. The technology works by dropping a weight down the shaft to gen

Description
Description | Green Gravity has secured a lease to conduct its first underground trial of gravity energy storage technology at the #4 shaft of the Russell Vale coal mine near Wollongong. The project involves installing safety equipment and repurposing old mine infrastructure to test a system that stores 150 kW of power using a 400-meter deep shaft. The technology works by dropping a weight down the shaft to generate electricity and pulling it up using excess renewable energy, similar to pumped hydro but using large mass. |
