Gravitricity Technology Turns Mine Shafts into Low Cost Power Storage Systems

How’s this for a clever energy storage idea, especially in places as heavily mined as Cornwall and parts of Devon?

A report by independent analysts at Imperial College London has found that Scotland-based Gravitricity’s gravity-fed energy storage system may offer a better long-term cost of energy storage than batteries or other alternatives – particularly in grid balancing and rapid frequency response services.

The company states its technology is ideally suited to network-constrained users and operators, distribution networks and major power users. The technology operates in the 1MW to 20 MW power range and enables existing grid infrastructure to go further in a renewable energy world. Full article here..
