VRB Energy, a clean technology innovator, has commercialized the largest vanadium flow battery cell stack (50 kilowatts) and power module (1 megawatt) on the market. This battery system has been certified by Underwriters Laboratories 1973, recognized as a global standard for commercially available battery energy storage.
A press release by the company states that the vanadium flow battery project has the ability to store and release 700MWh of energy. This system ensures extended energy storage capabilities for various applications. It is designed with scalability in mind, and is poised to support evolving energy demands with unmatched performance.
Vanadium flow batteries provide continuous energy storage for up to 10+ hours, ideal for balancing renewable energy supply and demand. As per the company, they are highly recyclable and adaptable, and can support projects of all sizes, from utility-scale to commercial applications.
The Xinhua Ushi ESS vanadium flow battery project - termed the world's largest - is located in Ushi, China.
Vanadium flow batteries are safe and reliable because they use the same electrolyte on both sides of the battery. This eliminates the risk of harmful corrosion or degradation over time.
VRB Energy's vanadium flow batteries use the same electrolyte on both sides of the battery, unlike some flow batteries that use different chemicals for the positive and negative sides.
