(459c) Redox Flow Battery Technologies and Applications

Redox flow batteries (RFBs) are increasingly being recognized as a prominent candidate for large-scale energy storage due to their advantages of high safety, decoupling of power and energy, long lifespan, quick response, and potentially low cost. To introduce this unique energy storage technology to the broader chemical and electrochemical engineering community, this talk will provide an overview on the working mechanism, development history, major components, and various chemistries of the RFBs. The talk will also cover new redox flow chemistries including aqueous and non-aqueous systems, electrode and membranes developed at Pacific Northwest National Laboratory (PNNL). User case examples of the application of RFBs from the Clean Energy Fund (CEF) projects sponsored by Washington State Department of Commerce will be discussed as well.
