The vanadium flow battery (redox flow battery), can absorb and stabilize the fluctuations of outputs predicated by renewable energy sources. Essentially, it’s a large scale energy storage system featuring a vanadium flow battery that charges and discharges depending on oxidation and reduction of vanadium ions in electrolytes.

As such, the lifecycle is long – 20 years – with little to no risk. This is why it can be used on a large scale safely. It also allows for real-time accurate monitoring of the remaining charge, along with ease of operation and virtually no limit to the charge/discharge systems. Perhaps its most notable point is that it is incombustible, which translates to no fire hazard.
