Copper flow batteries
Long-duration storage that powers the grid reliably and sustainably
Foundation
The copper flow battery explained
Unlike traditional batteries that store energy within solid cells, flow batteries store energy in liquid electrolytes kept in external tanks. By leveraging the unique chemical properties of highly abundant and recyclable copper, this innovative system provides a stable, efficient, and future-proof way to manage our growing energy grids and industrial needs.
Advantages
What sets copper apart
Built for the demands of modern grids
Process
How the system works
Three stages move energy through the battery reliably
Charging Up
Electrical current drives the deposition of copper, capturing and storing energy
Holding Steady
Energy is safely preserved in the liquid electrolyte untill it is needed
Delivering Power
The electrical current reverses, instantly providing reliable energy on demand
Performance
Designed to last through decades
Every specification reflects what grid operators and industrial facilities demand. Halide Energy batteries are engineered for the long game.
