## About

Based in New South Wales, Australia, and founded in 2021, Green Gravity Energy Pty. Ltd. operates as an energy storage company that enhances renewable energy efficiency and support global sustainability efforts through the development of energy storage technologies. In October 2024, Green Gravity raised AUD 9 million in Series A funding from investors HMC Capital, BlueScopeX, Pacific Channel, and Sumitomo Corporation. The firm as of December 2024, is led by its CEO, Mark Swinnerton.

Green Gravity harnesses disused mine shafts to store energy using gravitational potential. The technology lifts and lowers heavy weights to capture and release energy, offering a low-cost, long-duration, and environmentally sustainable solution for renewable energy storage. By repurposing existing mining infrastructure, Green Gravity reduces both costs and environmental impact. Unlike traditional storage methods, it avoids chemicals and provides long-lasting, efficient solutions. With its simplicity and low operational costs, the technology is poised to play a key role in the future of renewable energy, ensuring stable storage for wind and solar power.

The company plans to utilize the October 2024 funding to complete the remaining product development for its mineshaft-based gravitational energy storage technology.
