Gravity Energy storage

Our GraviStore underground gravity storage technology uses the power of gravity to offer some of the best characteristics of lithium batteries and pumped hydro storage.

Ideally suited to network-constrained users and operators, distribution networks and major power users, our technology operates in the 1MW to 20 MW power range and enables existing grid infrastructure to go further in a renewable energy world.

Key features:

With no cycle limit or degradation

Zero to full power in less than a second

Can run fast to deliver high power, or more slowly for longer duration

Levelised costs well below lithium-ion batteries

These special characteristics mean Gravitricity’s gravity energy storage is ideally suited to the following use cases:

Grid services. Delivering power to distribution and transmission network operators (DNOs and TSOs) for grid balancing and frequency regulation, allowing them to ensure quality and security of supply with a technology designed to last for decades.

Co-location. By coupling gravity storage with large scale renewable generation at the same site, solar farm owners and operators can time-shift solar supply to high price peak periods, reduce connection costs and stack revenue streams.

Industrial decarbonisation. On-site energy storage can support industries including mining, oil and gas and data centres to decarbonise their operations through reducing grid demand, increasing the resilience and reliability of supply, and delivering ancillary service income.

Energy access. Gravity storage can be designed into mini grids allowing utilities and mini grid developers to reduce infrastructure spend and deliver better energy access to rural and off grid communities, especially during non-daylight hours.
