U.S. Vanadium Successfully Recycles Electrolyte From Vanadium Redox Flow Batt17 Mar 2021 12:31
Successful VRFB Recycling Moves the World One Step Closer to Relying on 100% Renewable Energy Power Generation
U.S. Vanadium is pleased to announce that it has successfully demonstrated the ability to recycle the liquid electrolyte used in Vanadium Redox Flow Batteries (“VRFB”), a rapidly growing commercial technology that promises to enable intermittent renewable energy technologies such as solar and wind to provide power on a round-the-clock basis.
Because of their nearly unlimited energy storage capacity, high efficiency, zero emissions, very long cycle lives, and relatively low cost of available electricity on a lifecycle basis, VRFB energy storage systems are enabling consumers to utilize renewable energy systems for 100% of their actual power needs without having to rely on renewable energy credits and other accounting offsets.
“VRFB technologies are key to the U.S. and other nations in moving closer to truly 100% grid-level renewable energy power generation systems,” said Mark A. Smith, Chief Executive Officer of Hot Springs, Ark.-based U.S. Vanadium.
Against a background of increasingly prevalent waste disposal issues faced by lithium-ion batteries, VRFBs have the important benefit of its liquid electrolyte being nearly 100% recyclable. Vanadium electrolyte, and its ability to be recycled for continuing use, is considered to be a key advantage for the technology that is expected lead to increased worldwide adoption of VRFBs as an alternative to lithium-ion batteries.
U.S. Vanadium, a leading U.S. producer of high-purity vanadium and VRFB electrolyte products, recently demonstrated the technical and economic feasibility of recycling VRFB electrolyte, provided by VRFB industry leader Invinity Energy Systems plc (LSE:IES).
“This technological breakthrough represents a large leap forward in realizing the revolutionary potential of vanadium redox flow battery systems,” said Mr. Smith. “I cannot understate the importance to the power generation industry, and the future of renewable energy in general, of enabling VRFB electrolyte recycling. U.S. Vanadium looks forward to assisting in the manufacturing and recycling of VRFB electrolyte from systems around the world.”
The VRFB electrolyte recycling initiative at U.S. Vanadium, where a vanadium recovery rate of 97% was achieved, was led by Mike Woolery, vanadium technologist for U.S. Vanadium and a Rensselaer Polytechnic Institute chemical engineer with over four decades of experience in the vanadium industry.

“Successfully recycling and restoring VRFB electrolyte presents a number of difficult technical and economic challenges,” said Mr. Woolery. “I am very pleased with the outcome of this effort and with U.S. Vanadium’s commitment to stay on the leading edge of initiatives s
