Dr. Amgad Elgowainy is a senior scientist and the leader of the Electrification and Infrastructure Group at Argonne National Laboratory, leading a large team of researchers covering engineering process modeling, environmental life cycle analysis and techno-economic analysis of energy systems, fuel infrastructure and vehicle technologies. His research projects support governmental agencies, OEMs, energy industries, and utility and gas companies. He is serving as a technical expert on several Technical Teams of the US DRIVE and the 21st Century Truck Partnerships. He also served as a technical expert in several of the International Energy Agency (IEA) Technical Collaboration Programs on electric vehicles, hydrogen, and fuel-cell vehicles, and is currently supporting the development of greenhouse gas (GHG) emissions accounting methodology for the International Partnership of Hydrogen Economy (IPHE). Dr. Elgowainy has contributed to the development of the environmental life cycle analysis models (GREET®) since 2001, and has led the development of the hydrogen infrastructure technoeconomic suite of models (HDSAM, HRSAM and HDRSAM). These models are recognized by thousands of users globally. Dr. Elgowainy authored and coauthored more than 200 technical publications, edited a volume on Electric, Hybrid and Fuel Cell Vehicles, and authored several book chapters on low carbon fuels and electrification of transportation. He developed several licensed patents related to hydrogen fueling methods. He received numerous government and industry awards. In 2020 he was recognized by U.S. DOE Secretary Achievement Award related to his contribution to nuclear hydrogen demonstration projects. Dr. Elgowainy earned his PhD in Mechanical Engineering from the University of New York at Buffalo in 1994, and has taught many undergraduate and graduate engineering and environmental courses at University of Chicago, Purdue University Northwest, Tennessee State University, and University at Buffalo.
