STORAGE SOLUTIONS
E22’s cost effective flow batteries are the best partner to make the renewable revolution a reality.
Our technology
Vanadium Redox Flow Batteries
Our Vanadium Redox Flow Batteries (VRFBs) are designed to be robust, bankable, cost effective, and long lasting batteries. E22’s flow batteries employ strong track record and proven experience in vanadium redox flow chemistry with an industrial optimization to reach reliability at the lowest cost.
VRFBs utilize a recyclable, with non-chemical degradation, non-dangerous iron-based electrolyte valid for unlimited cycles, and with a proven track record over 12,000 cycles of power with marginal maintenance cost.

Why VRFB?
Flow batteries can provide a full range of power (kW) and energy (kWh) applications from the very same unit: all-in-one. Vanadium Redox Flow Batteries can perform from short to long duration, including simultaneously service for ramping and frequency regulation. Also system provide the advantage of no state-of-charge 100% SOC, 100% net energy and no duty cycle limitation.
As a remarkable feature of the VRFBs, power and energy are decoupled, enabling maximum system flexibility.
No other technology can match the advantages of E22’s Redox batteries.
