While not flammable, the electrolyte in VRB systems is corrosive. It is composed of a sulfuric acid-based solution similar to common automotive lead-acid batteries. While very similar to such batteries, VRBs are notably different and deemed safer than lead-acid.
Vanadium flow batteries consist of two tanks containing vanadium electrolyte, a pump system to circulate the electrolyte, and a fuel cell stack where the electrochemical reactions occur.
Self-contained and incredibly easy to deploy, they use proven vanadium redox flow technology to store energy in an aqueous solution that never degrades, even under continuous maximum power and depth of discharge cycling. Our technology is non-flammable, and requires little.
SDG&E's 2MW/8MWh vanadium system proved 30% lower lifecycle costs than lithium alternatives. It's like comparing a diesel generator to a Prius-different tools for different jobs. Industry forecasts suggest we'll see: 2025: $250-$400/kWh (we're already here!).
A vanadium flow battery is a type of electrochemical energy storage system that uses vanadium ions in different oxidation states to store and release energy.
Specifically, lithium-ion systems typically range from $400 to $600 per kilowatt-hour, while flow batteries can cost between $700 and $1,200 per kilowatt-hour. They're scalable, long-lasting, and offer the potential for cheaper, more efficient energy storage.
These advanced energy storage systems are gaining traction as a game-changer for renewable energy integration, offering scalability, longevity, and environmental benefits that traditional batteries struggle to match.
