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 president and CEO Gary Yang and CTO 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 containerized 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.

UniEnergy sells a 500 kW, 2 MWh fully integrated AC Battery called a Uni.System. Each AC battery is capable of 600 kW AC peak power, 2.2 MWh AC peak energy. Each Uni.System is made of four DC batteries, each housed in a 20 ft shipping container and a 5th shipping container that holds the Power Conversion System (inverter and rectifier) and the transformer to deliver AC power. This product is sized to be a building block for utility–scale deployments which need multi-Megawatt installations or larger commercial and industrial customers. The company is planning to begin deployments of a smaller 100 kW system in 2016 with a deployment planned for NY.
