What is gravity energy storage (GESS)?

The Switzerland and California-based company announced that it is entering the first phases of commissioning for its first commercial-scale gravity energy storage system (GESS). Slated to be fully grid-interconnected in Q4 2023, the gravity tower will mark the world’s first non-pumped hydro gravity-based storage facility.

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.

Could gravity energy storage be a new form of energy storage?

Energy Vault, a Swiss company, is betting on new forms of energy storage, including its gravity energy storage systems (GESS), which have been dubbed EVx and look from the outside like large buildings filled with concrete blocks. The company wants to harness gravity and kinetic energy with an automated weighting system.

Does Energy Vault have a GESS storage system?

Energy Vault has successfully interconnected its GESS storage system. A development that was to Rudong EVx as the world’s first commercial scale non-pumped hydro gravity energy storage system. However, final provincial and state approvals are still awaited before it can be operated commercially.

Where is the 25 MW / 100 MWh project located?

The 25 MW / 100 MWh project in Jiangsu Province, China. The project is located near a wind power facility outside of Shanghai in Jiangsu Province, China. It is a 25 MW / 100 MWh storage system that makes use of the company’s new “ribbon” based lifting systems.

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.
