UniEnergy Technologies

UniEnergy Technologies (UET) is a U.S. vanadium redox flow battery manufacturer in Mukilteo, Washington, which manufactures megawatt-scale energy storage systems for utility, commercial and industrial customers. The company was founded in 2012 by Dr. Gary Yang and Dr. Liyu Li to commercialize a new Vanadium electrolyte formulation the pair had developed while working at PNNL. The new formulation, a mixed-acid solution, was patented by PNNL and the patent was licensed to UET for commercialization. The mixed-acid vanadium electrolyte allows for a wider temperature range for operations, and double the energy density of the traditional vanadium electrolyte. 
The company has designed a megawatt-scale flow battery using this new electrolyte for the purpose of allowing rapid deployment, manufacturing repeatability and lower costs. The company also employs an R&D team which works to make advances on the electrolyte chemistry and stack design.
UET has a subsidiary in Germany, Vanadis Power which provides sales and services for Europe. The company has partnerships with Bolong New Materials, a vanadium electrolyte manufacturer, Rongke Power, the vanadium flow battery stack manufacturer. In December 2015 the company completed their B round funding series which included a major investment from Orix Corp.
Products.
UniEnergy sells a 10kW, 34kWh fully integrated flow battery called the ReFlex. This product is sized to be a building block for commercial and utility scale deployments from kilowatts to multi-megawatt installations.
