Energy Vault Wins Big With Gravity Storage In China
The Energy Vault (NRGV) installation at Rudong, near Shanghai, is the first gravity energy storage system to be commissioned in the world. The EVx facility towers above the wind turbines whose energy it will store. Energy Vault (NYSE: NRGV) will license six additional EVx gravity energy storage systems in China just months after starting the commissioning of the world’s first GESS facility near Shanghai.
Comprehensive Insights into Gravity Energy Storage
Gravity energy storage systems (GESS) utilize gravitational potential energy to store and release energy. This innovative technology is designed to address the challenges of energy storage, particularly for renewable sources like wind and solar. By lifting and lowering heavy blocks, these systems can effectively store excess energy generated during peak production times and release it when demand is high.
Energy Vault’s approach to gravity storage is particularly noteworthy. Their installations use excess renewable energy to lift massive composite blocks. When energy is needed, the blocks are dropped, converting potential energy back into electricity. This method not only provides a sustainable energy solution but also boasts a round-trip efficiency (RTE) of over 80%.
