DOE's Energy Storage Program is funding research to develop next-generation vanadium redox flow batteries (VRBs) that reduce costs by improving energy and power densities, widening the operating temperature window, and simplifying and optimizing stack/system designs. These efforts build on Pacific Northwest National Laboratory research that has developed new redox electrolytes that enable increased VRB operating temperatures and energy storage capabilities.

The City of Painesville, OH, and its partners will demonstrate vanadium redox battery storage capacity at the 32 megawatt (MW), coal-fired Painesville Municipal Electric Plant (PMEP). Using stored power enables the facility to attain the same daily output requirement, more efficiently and with a lower carbon footprint. When the project is fully implemented, the plant will operate at a constant 26 MW, 80 percent of rated capacity.
