Slated to be fully grid-interconnected in the fourth quarter of 2023, the gravity tower will mark the world's first non-pumped hydro gravity-based storage facility. The project is located near a wind power facility outside of Shanghai in Jiangsu province, China. The EVx ™ system is projected to achieve an impressive round-trip efficiency exceeding 80%. This places the new gravity system at the forefront of energy storage efficiency compared to alternative long duration energy storage methods such as mechanical, thermodynamic, compressed air, and flow. Rudong EVx, a pioneering gravity energy storage project on the outskirts of Shanghai, has successfully integrated into China's national grid, marking a transformative step in the storage and distribution of renewable energy. 7 GWh, which will generate future project revenue royalty streams to Energy Vault as systems are built and commissioned. There are many ways to store energy, from electrochemical batteries, to pumped hydro, to iron-air batteries, to flywheels, and more. Energy Vault has taken a new approach. Gravitricity has partnered with firms in the US and Germany to deploy its gravity energy storage solution while Energy Vault has provided an update on its China project.
