Gravity energy storage
A new form of renewable energy storage to power a cleaner world
As the world generates more and more electricity from intermittent renewable energy sources, there is a growing need for technologies which can capture and store energy during periods of low demand and release it rapidly when required.

Fast, long-life energy storage
At Gravitricity we are developing a novel storage technology which offers some of the best characteristics of lithium batteries and pumped storage.
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.
50-year design life
with no cycle limit or degradation
Response time & efficiency
zero to full power in less than one second
Versatility & simplicity
can run slowly at low power or fast at high power
Cost efficiency
levelised costs well below lithium batteries
Our 250kW demonstrator project
We have constructed a 15-metre high test rig at the Port of Leith. This 250kW concept demonstrator uses two 25-tonnes weights suspended by steel cables connected to two winches. The demonstrator is being used to validate engineering simulations, which will feed into full-scale system design, and to confirm Gravitricity’s unique selling points.
