Currently implemented gravity energy storage projects

Can gravity energy storage power 9 homes a year?

The company's first commercial grid-scale project using its proprietary gravity energy storage technology in Rudong, near Shanghai, was connected to the grid in December 2023 and can store up to 100 MWh. In other words, this is enough electricity to power nine homes for a whole year just from stored energy.

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.

What is gravity & how does it work?

This allows renewable energy to be used when it is needed. Gravitricity is developing a novel storage technology which offers some of the best characteristics of lithium batteries and pumped storage. Its patented technology is based on a simple principle: raising and lowering a heavy weight to store energy.

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.
