Switzerland’s Energy Vault installs EVx storage systems in China

All five EVx projects have an estimated 3.26 GWh capacity and more than $1b in value.

Swiss-based energy storage producer Energy Vault Holdings, Inc. has deployed five new EV gravity energy storage systems (GESS) in China.

The delivery, supported by China Tianying Inc. (CNTY), will bring its proposed EVx projects to seven, bringing a 3.26 GWh capacity with more than $1b in value and including a 5% project royalty. Among the projects include the 100 MWh EVx GESS in Rudong and the 2 GWh EVx GESS in Tong Liao, Inner Mongolia.

CNTY began the process of grid integration last September 2023 for its first EVx system, with the final commissioning in Rudong of its 35 kV overhead power line to the local substation.

In turn, the Rudong EVx system will be the first commercial, grid-scale gravity energy storage system in the world to serve as an alternative to energy storage assets, which represents 90% of the global storage capacity.

“As we commission the first 100MWh system in Rudong, which we have optimized for the China market requirements, we are pleased to be quickly expanding this groundbreaking technology that will enable intermittent wind and solar power generation to more readily replace other fossil fuel-based generation and thus help accelerate China’s clean energy transition and achievement of its net carbon neutral goals.” Yan Shengjun, Chairman of China Tianying, said.

Alongside the delivery, CNTY is preparing the installation of a 2 GWh EVx system, supporting the zero-carbon industrial parks in Tong Liao, Inner Mongolia.
