Gravitricity Ltd is an energy storage company based in Edinburgh, UK. We are developing a grid-scale mechanical energy storage technology which shares many of the best attributes of lithium batteries and pumped storage – offering fast, versatile electricity storage which can be located exactly where it is required. It will appeal to network-constrained users and operators, distribution networks and major power users and has potential to provide significant network benefits including reduced overall costs. Over the next 12 months we will be undertaking sub-system design and testing at an existing mine site, and aim to trial our first full-scale prototype in 2022. Our demonstrator testing concluded in summer 2021.
