Gravitricity 250kW demonstrator stores power for first time

Gravitricity has successfully commissioned their 250kW energy storage demonstrator – proving the capability of their novel gravity-powered technology.

It provides a cost-effective, long-life alternative to lithium-ion batteries, without the need for rare earth metals.

Their demonstrator has been built above ground, whilst future commercial projects will be underground – using either decommissioned mine shafts or purpose-sunk shafts.

Gravitricity’s ‘battery’ works by raising one or more heavy weights in a deep shaft and releasing them when energy is required.

A full-scale 8MW project would store enough electricity to power 5000 homes for an hour.
