One of the universe’s fundamental forces, gravity is set to power an energy storage project in Edinburgh.
Located at Forth Port’s Prince Albert Dock, the £1 million demonstration project will use underground shafts and massive weights to store energy.
The plant comprises a 15-metre tower, two 25-tonnes weights suspended by steel cables and two fully grid-connected generator units.
The project is supported by a £640,000 grant from Innovate UK.
Frances Tierney, Engineering Project Manager, said: “We calculate we can go from zero to full power in less than a second, which can be extremely valuable in the frequency response and backup power markets.
