Rudong, China Gravity Energy Storage System

Energy Vault’s groundbreaking EVx™ is the world’s first commercial-scale Gravity Energy Storage System (GESS), providing industry leading round-trip efficiency and a 35-year operating life.

Project Overview

The 25 MW/100 MWh EVx™ Gravity Energy Storage System (GESS) is a 4-hour duration project being built outside of Shanghai in Rudong, Jiangsu Province, China. The EVx™ is under construction directly adjacent to a wind farm and national grid. It will augment and balance China’s energy grid through the shifting of renewable energy to serve the State Grid Corporation of China (SGCC). The system is expected to be fully grid interconnected by the end of 2023 as planned with local grid authorities.
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 battery systems. With a projected operational lifespan of 35 years, this project aligns with China's "Zero-Carbon parks" initiative and national "30-60" net carbon neutral plan. This inaugural deployment sets a benchmark for worldwide collaborations in decarbonization technology.

Rudong Project Highlights

Intelligence
Innovative

The Rudong project is the world's first commercial scale deployment of a non-pumped hydro, gravitational energy storage system.

Atom Editor
High Round Trip Efficiency 

An anticipated 80% round trip efficiency puts the EVx™ ahead of competing long duration technologies such as flow battery, thermal, and compressed air energy storage.

Increase
Performance Longevity

No degradation of the storage medium requiring augmentation; no self-discharge; and an impressive 35-year project life span leads to sustained performance over an extended time horizon.

Circuit-1
Localized Supply Chain 

The EVx™ design enables compliance with domestic content requirements through regional sourcing of labor and materials while simultaneously limiting exposure to high-cost material market changes.
