How does gravity energy storage work?
The firm’s technology works by raising weights in a deep shaft and releasing them when energy is required. The technology is similar to that employed by Switzerland-headquartered and NYSE-listed Energy Vault, whose CEO Robert Piconi provided an update to its first commercial gravity energy storage project in Rudong, China, in a shareholder letter.
Is energy vault building a new energy storage system in China?
According to CNET, Energy Vault is building its 400-foot-tall project in China for China Tianying, a waste management and recycling company. The project is designed to have an energy storage capacity of 100 megawatt-hours, which can power 3,400 homes for a day, and the system is expected to be completed in June.
Which energy storage project is under construction in China?

Energy Vault has connected its first commercial EVx gravity-based energy storage system to the grid in China, while construction has been launched on three others, all-in-all totalling 468MWh of capacity.
What is Energy Vault doing now?
It also revealed that the concrete foundations have been completed for the firm’s first gravity storage project in the US, in Georgia with Enel Green Power. Energy Vault now provides a range of energy storage solutions including battery storage and green hydrogen and is forecasting for US$325-425 million in revenues this year.
Can gravity store energy at a decommissioned mine?
The company plans to fund up to five projects at current and former mines. Gravitricity has also been contracted to investigate the potential of storing energy at a decommissioned mine in Halle, Germany, by the mine’s owner Geiger Group.
How will Energy Vault support China's national energy grid?
Energy Vault said that upon completion, the systems will support the balancing of China’s national energy grid through the storage and delivery of renewable energy. The Rudong and Zhangye projects have been designated as new energy storage pilot demonstration projects by China’s National Energy Administration.
