How EARTHENVOLT stores energy with gravity
Our grid-scale gravity battery platform converts surplus renewable power into stored potential energy, then dispatches it back to the grid with predictable performance, sustainable materials, and commercial-scale flexibility.
How the system works
EARTHENVOLT combines proven mechanical principles with modern controls to deliver long-duration storage for utilities, grid operators, and enterprise-scale energy users.
01
Charge with surplus power
When renewable generation exceeds demand, electric motors lift mass within a vertical storage structure, converting excess electricity into stored gravitational potential energy.
02
Hold energy efficiently
The system stores energy without combustion, rare materials, or fuel consumption, enabling stable long-duration performance with low operational complexity.
03
Discharge on demand
When the grid needs support, the descending mass drives generators to return electricity with controlled output for balancing and reliability services.
04
Scale by site type
The platform can be adapted in any environment, large cities, and large infrastructure projects to match local grid and land conditions.
