SEMINAR | Organic Aqueous Flow Batteries for Massive Electrical Energy Storage: Michael J. Aziz at FBK

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. Solid-electrode batteries are drained far too soon, when discharged at their rated power, to economically fill the gaps in photovoltaic or wind temporal power profiles. 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, particularly those utilizing redox-active metals such as vanadium or precious metal electrocatalysts. We have developed high performance flow batteries based on the aqueous redox behavior of small organic molecules such as quinones. The redox active materials can be very inexpensive and exhibit rapid redox kinetics and long lifetimes. This new approach should enable massive electrical energy storage at greatly reduced cost.

Michael J. Aziz 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. 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 Harvard's University-Wide Graduate Consortium on Energy and Environment.

Michael J. Aziz will be in FBK thanks to the collaboration with Green Energy Storage, a company focused ont he development of organic flow batteries that collaborates with FBK in the research and innovation activities on this field. In particular, the research units ARES (Applied Research on Energy Systems) e FMPS (Functional Materials and Photonic Structures) of the Centre for Materials and Mycrosystems, and ES (Embedded Systems) of the Centre for Information and Communication Technology are involved.  

Luigi Cremaresponsible of the research activies on flow batteries, within Georg Pucker (FMPS) and Alessandro Cimatti (ES), coordinate the team of researchers dedicated to the identification of innovative materials for the specific application, the development of components and battery prototypes with real-scale advanced performances and for the configuration of a full system control unit based on predictive management tools.
