Applied Physics Colloquia

"Organic Aqueous Flow Batteries for Massive Electrical Energy Storage" with Mike Aziz, Professor of Materials and Energy Technologies.

The ability to store large amounts of electrical energy is of increasing importance with the growing fraction of electricity generation from intermittent renewable sources such as wind and solar. Flow batteries show promise because the designer can independently scale the power (electrode area) and energy (arbitrarily large storage volume) components of the system by maintaining all electro-active species in fluids. Wide-scale utilization of flow batteries is limited by the abundance and cost of these materials. We have developed an approach to electricity storage using the aqueous redox chemistry of small, inexpensive organic molecules such as quinones. The absence of active metal components in both redox chemistry and catalysis represents a significant shift away from the direction modern battery R&D has been taking. This new approach may enable massive electrical energy storage at greatly reduced cost.

Speaker Bio: Michael J. Aziz received a Ph.D. in Applied Physics from Harvard in 1983, having written a thesis on crystal growth kinetics under David Turnbull. He spent two years at Oak Ridge National Laboratory as Eugene P. Wigner Postdoctoral Fellow developing ion and laser beam materials processing. He has been a member of the faculty at what is now the Harvard John A. Paulson School of Engineering and Applied Sciences since he joined in 1986 and is now Gene and Tracy Sykes Professor of Materials and Energy Technologies.  Aziz has made significant contributions to a number of fields in applied physics and materials science.  His recent research interests include novel materials and processes for energy technology and greenhouse gas mitigation. He is co-inventor of the organic aqueous flow battery and directs a multi-investigator research program on stationary electrical energy storage.  He is the Faculty Coordinator for the Harvard University Graduate Consortium on Energy and Environment, for which he developed a quantitative course on Energy Technology for a group of students in diverse disciplines. He is authoring a textbook, "Introduction to Energy Technology: Depletable and Renewable", to be published by Wiley-VCH.
