Electrochemical energy storage (EES) systems offer the potential for a more secure and cleaner electrical grid, from improving resiliency and reliability to improving the implementation of renewable into the current infrastructure. Pacific Northwest National Laboratory (PNNL) is currently conducting extensive research and development efforts into multiple energy storage systems under the Department of Energy – Office of Electricity (DOE-OE.) Energy Storage Program including vanadium redox flow batteries.     This talk will focus on the latest developments in redox stack development including stack design and performance validation utilizing PNNL’s mixed acid redox electrolyte.
