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.
The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery which employs vanadium ions as charge carriers.
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.
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.
25+ Year Operational Lifespan: Vanadium flow batteries can operate for over 25 years, maintaining full capacity throughout their lifecycle. This longevity matches or exceeds the lifespan of other renewable energy assets like solar panels.
This guide helps you compare indoor and outdoor deployment, then choose a mix that fits your riders, regulations, and growth plan-with HelloPower (HelloSwap in Thailand) as your partner from design to operation.
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.
