The U.S. Environmental Protection Agency (EPA) recently recognized Mukilteo, Wash.-based flow battery provider UniEnergy Technologies (UET) with a Green Chemistry Challenge Award.
The award acknowledged UET’s work in partnership with Pacific Northwest National Laboratory (PNNL) on an advanced vanadium redox flow battery, which was originally developed by PNNL and commercialized by UET.
“We congratulate those who bring innovative solutions that will help solve problems and help American businesses,” EPA Administrator Scott Pruitt said in a June 8 statement. “These innovations encourage smart and safe practices, while cutting manufacturing costs and sparking investments. Ultimately, these manufacturing processes and products spur economic growth and are safer for health and the environment.”
EPA said the battery works in a broad temperature range with one-fifth the footprint of previous flow battery technologies. In addition, the electrolyte is water-based and does not degrade, and the batteries are non-flammable and recyclable.
In April, the University of Alaska Fairbanks named UET the winner of the Microgrid Project laboratory testing award in the Alaska Center for Microgrid Technologies Commercialization industry competition. The award includes 25 dedicated lab days, consultation with staff and testing in the Power Systems Integration Lab at the UAF Alaska Center for Energy and Power. According to the university, the lab can evaluate equipment under a range of real-world scenarios and emulates the microgrids and operating conditions found in rural Alaska.
“With the accelerating deployment of microgrids globally, including in cold-weather climates, the need for long-duration and long-life energy storage solutions such as UET’s advanced vanadium flow batteries is now widely-recognized,” Russ Weed, UET’s vice president for business development and marketing, said in an April statement.
