Technical FAQs 4

What is gravity energy storage system (GESS)?

The 25 MW/100 MWh EVx™ Gravity Energy Storage System (GESS) is a 4-hour duration project being built outside of Shanghai in Rudong, Jiangsu Province, China. The EVx™ is under construction directly adjacent to a wind farm and national grid.

Why is gravity the future of energy storage?

As the world generates more electricity from renewable energy sources, there is growing demand for technologies which can store excess energy produced and release it on demand. Gravitricity develops innovative, long duration underground storage technologies that deliver flexible, low-cost solutions for energy storage.

How does gravity energy storage work?

Gravitricity develops below ground gravity energy storage systems and raised £40 million to commercialise projects in January this year, as covered by our sister site Solar Power Portal. The firm’s technology works by raising weights in a deep shaft and releasing them when energy is required.

Where is the gravity energy storage system based?

The research and development of the gravity energy storage system has been based in Ticino and operational since 2019 with its own R&D centre. The commercial demonstration unit has been connected to the Swiss national utility grid and used for two years of testing and software commissioning.
