Energy Vault Demonstrates Large‑Scale Gravity Storage in China

Energy Vault’s Rudong gravity‑storage plant in China has reached commercial scale, proving that a first‑of‑kind project can be built with local supply chains and government backing. The facility uses locally sourced concrete, steel, motors, power electronics and industrial construction, and it has been integrated with the national grid under coordinated support. By operating at this size, the project removes many of the typical excuses that plague early‑stage energy storage deployments. The plant’s performance sets a demanding benchmark for battery storage, highlighting the potential of gravity‑based systems to compete on cost and reliability. The demonstration shows that large‑scale gravity storage can be deployed rapidly with domestic resources, offering a viable alternative to battery‑based solutions for grid balancing and renewable integration.
