ELECTROCATALYSIS FOR SUSTAINABLE ENERGY TECHNOLOGIES

Drew Higgins, Postdoctoral Fellow, Stanford University


RESEARCH INTERESTS

Achieving a sustainable energy economy is among the biggest challenges of the 21st century. Electrochemical energy storage and conversion devices (i.e., batteries, fuel cells, electrolyzers) will be integral components of clean energy infrastructures, as they boast zero emission operation and high theoretical efficiencies. These systems, however, are not currently techno-economically viable at scale, primarily due to electrocatalyst limitations. My research interests lie in the development and device integration of advanced, high performance electrocatalysts. These materials have the potential to address the performance, durability and cost challenges facing many emerging clean electrochemical technologies. The ultimate goal is to transform the landscape of the energy sector by providing cost competitive devices that can be applied in the transportation sector, grid scale energy storage, or industrial applications.


FUTURE PLANS

My career goal is to manage a research group at an academic institution that works on the cutting edge of clean energy technologies, particularly with respect to energy transformations and electrocatalysis. In the short term, my research will be focused on two thrust areas: (1) Electrochemical Carbon Dioxide Reduction, an integral process of artificial photosynthesis that converts CO2 directly into fuels or industrial chemicals; and (2) Oxygen Electrocatalysis,the most pertinent and performance limiting processes occurring in fuel cell and electrolyzer devices. I envision early work focusing on the development of new electrocatalyst materials that will be characterized and electrochemically evaluated to understand performance capabilities. The best in class electrocatalysts will be engineered into electrode structures for device performance testing and optimization.

In the long term, my vision is to lead a research program that spans: (1) Fundamental Electrocatlaysis/Surface Science; (2) Electrocatalyst Design and Synthesis; and (3) Electrochemical Device Design, Integration and Prototype Demonstration. These three core areas will be strategically integrated to operate in a feedback loop, whereby new knowledge generated in one area will be applied to achieve advances in other areas. Over time, this research program will be expanded to encompass different thrust areas that are synergistic with those listed above, including hydrogen electrochemistry, new battery chemistries (i.e., metal-air or sodium-ion) and electrochemical purification techniques. The overarching goals of this research program will be two-fold. First, is to develop innovative material solutions and technologies that address the pertinent energy and environmental challenges facing the modern world. Second, is to educate and train the next generation of scientists and engineers that will be lifelong contributors in this sector of increasing global importance. Academic, industrial and government collaborations will be fostered and leveraged to establish an interdisciplinary research environment, and to provide targeted training and avenues for research personnel to enter the workforce.
