Presented By: Aerospace Engineering
Chair's Distinguished Lecture: Low-Carbon Transportation Fuels - Restarting the Conversation Around Hydrogen
Margaret Wooldridge
Professor
Department of Aerospace & Mechanical Engineering
University of Michigan
Hydrogen is an attractive energy carrier because it emits nearly zero carbon emissions when the hydrogen is sourced from a carbon neutral process. Although many pathways for hydrogen production exist, the primary barrier to widespread use of H2 remains the costs associated with H2 synthesis, storage and distribution. If costs can be reduced; however, there are additional challenges to the design of combustion systems that use high concentrations of hydrogen. You might think H2 is the simplest combustion fuel, so we should be able to build H2 engines with high confidence in their performance. However, H2 is a tricky gas that likes to defy expectations. Some examples of the anomalous combustion behavior of hydrogen will be presented here. The experimental results include performance and imaging data from H2 spark-ignition engine studies and fundamental studies of hydrogen ignition. The discussion focuses on understanding the hydrogen properties important for improving predictive performance of H2-fuels engines.
About the speaker...
Professor Margaret Wooldridge is an Arthur F. Thurnau Professor in the Departments of Mechanical Engineering and Aerospace Engineering and the Director of the Dow Sustainability Fellow Program at the University of Michigan. She received her Ph.D. and M.S. degrees in mechanical engineering (M.S.) from Stanford University and her B.S. M.E. degree from the University of Illinois at Champagne/Urbana. Prof. Wooldridge was on the faculty at Texas A&M University in 1995 before joining the University of Michigan in 1998. Her research program spans diverse areas where high-temperature chemically reacting systems are critical, including power and propulsion systems, fuel chemistry, and synthesis methods for advanced nanostructured materials. Her research team has pioneered methods for characterizing fundamental fuel properties and performance in modern spark-ignition and gas turbine engines. She is a 2013 recipient of the Department of Energy Ernest Orlando Lawrence Award and a fellow of the Combustion Institute, the American Society of Mechanical Engineers and of the Society of Automotive Engineers.
