Construction of a gravity-based storage facility has begun in China

At Rudong in Jiangsu Province, China, Energy Vault, Atlas Renewables, and China Tianying have begun work on a 100 MWh (megawatt-hour) gravity-based storage facility close to the national grid site and a wind farm.

The EVx system, China’s first, will assist supplement and balancing the country’s national energy grid by delivering renewable power to the State Grid Corporation of China. The start of EVx construction follows the announcement of a renewable energy storage license and royalty deal with Houston-centered Atlas Renewable and its principal shareholder China Tianying.

“Our maiden commercial EVx installation in China is a critical landmark for Energy Vault and the People’s Republic of China as it chases its decarbonization goals,” said Robert Piconi, who is the co-founder, chief executive officer, and chairman of Energy Vault.

In order to reach its decarbonization targets, China is quickly growing its usage of renewable energy and enacting annual energy storage quotas. “We are delighted that EVx as well as our energy management system software have already acquired local regulatory approval and are now being deployed as a crucial enabling technology to help China achieve its energy shift and carbon neutrality goals.”

China emitted higher metric tons of greenhouse gases in 2021 than the next 4 largest nations combined, and it is on track to continue increasing emissions until 2030, according to current plans. “We must act quickly to reverse this trend, and we will do so in collaboration with local allies Atlas Renewable and China Tianying.”

“The world’s first deployment of Energy Vault’s groundbreaking EVx technology is occurring in China, and it exemplifies US-China collaboration at its best,” said Atlas Renewable CEO Eric Fang. This project indicates China’s seriousness about its COP26 promises and will act as a paradigm for worldwide decarbonization.

“The Rudong project will be historically significant as a road ahead, supported by both American and Chinese private businesses working together collaboratively and successfully for a common climate goal: non-carbon-based energy storage which fully completes the energy production and consumption cycle of renewable electric power supplied from non-carbon sources,” said China Tianying chairman Yan.

The gravity-based solutions from Energy Vault are based on the physics and mechanical engineering basics of pumped hydroelectric energy storage, but instead of water, they use custom-built composite blocks constructed from low-cost and locally obtained materials such as coal combustion residuals (coal ash), local soil, mine tailings, and decommissioned wind turbine blades.
