gravity-based energy storage

A group of researchers in China has developed an energy management system for modular gravity storage. Compared to single block gravity storage, the modular counterpart offers more flexibility in output power, ease of mass production of related equipment and better flexibility in the selection of weights.

Green Gravity, an Australian energy storage startup, says it will explore opportunities to deploy its gravitational energy storage technology in Europe, after signing an agreement with Romanian state-owned energy producer Complexul Energetic Valea Jiului SA.

Energy Vault has started commissioning a 25 MW/100 MWh energy storage facility adjacent to a wind power facility near Shanghai.

Australian renewables startup Green Gravity has teamed with underground mining contractor RUC to accelerate the commercialization of its gravitational energy storage tech.

Scotland’s Gravitricity is developing gravity-based storage facilities in former mine shafts to stabilize electricity networks at 50 Hz, by responding to full power demand in less than a second. CEO Charlie Blair speaks to pv magazine about the potential and limitations of the tech, and how it compares to lithium-ion battery storage.

Robert Piconi, CEO of gravity storage specialist Energy Vault, makes the case for the US company’s long-duration energy storage solutions as an alternative to lithium-ion batteries, and discusses the ideal project size from an economic perspective.

UK-based Gravitricity plans to set up a pilot demonstration project for its gravity energy storage systems in India.

Switzerland’s Energy Vault will support Indian state-run power producer NTPC by deploying its gravity-based energy storage technology and software solutions.

Australia-based mining giant Fortescue has started the development of an electric train that recharges itself using gravity, after settling its recent purchase of UK-based Williams Advanced Engineering.

From pv magazine USA The gravity-based energy storage tower developed by Energy Vault has reached commercialization, with the company signing an agreement with DG Fuels to supply 1.6 GWh of energy storage. The tower will be charged with solar photovoltaic energy. The dispatched storage will support the creation of renewable hydrogen, biogenic based, synthetic aviation […]
