THE FIRST PRODUCTIZED FACTORY-BUILT FLOW BATTERY

Avalon has built the first productized and factory-built flow battery produced in high volumes for consistency and reliability, rather than a series of custom-engineered one-off projects.

AFB3 is self-contained and incredibly easy to deploy. It uses proven vanadium redox flow technology to store energy in an aqueous solution that never degrades, is non-flammable, and requires little maintenance and upkeep. All of Avalon’s batteries have a built-in DC:DC converter to provide consistent DC voltage for a direct connection to an inverter.

Available in banks of ten or 100 with integrated bank controls.

PERFORMANCE THAT NEVER DEGRADES

The Avalon™ Flow Battery’s exceptional durability means performance that never declines.

The anodes and cathodes inside the battery are inert, so performance after 25 years is essentially the same as new.

VANADIUM DOES THE HEAVY LIFTING

Vanadium is a non-toxic, widely-available metal that is typically used for strengthening steel, lightening titanium alloys and even as a dietary supplement. Vanadium is produced globally, either by recycling wastes from power generation or steel manufacturing, or from primary mining operations. Massive vanadium reserves are present in the USA, Canada, China, Brazil and South Africa; no significant sources currently exist within so-called “conflict regions”.

The exceptional durability, performance, and safety of the Avalon™ Flow Battery has been validated by third-party independent engineers and regulatory agencies.
