Gravity-powered batteries generate electricity when the wind dies down | Scotland

A company aiming to use old mine shafts as batteries to store renewable energy is to build a demonstration project showcasing its technology in Scotland.

Gravitricity believes that it can use large weights on cables attached to winches on the surface to help to compensate for the intermittent nature of wind farms.

The company estimates that the cost of its technology would be lower than the large-scale lithium ion battery deployment being considered by many renewable energy producers.

The Gravitricity method means that on days when more electricity is being generated than is needed by the grid the weight would be lifted to the top of the mine shaft. Then when demand is outstripping supply the weight can be lowered, with the movement of the
