Dr. Guiyan Zang is the technoeconomic analysis research lead at the MIT Energy Initiative (MITEI), where she leads the research of techno-economic analysis (TEA), life cycle analysis (LCA) and supply chain analysis. She has contributed to the projects on low-carbon fuel production (electro-fuel, ammonia, methanol, hydrogen, Fischer–Tropsch fuel), Industrial decarbonization (Iron/steel, refinery, cement, ethylene), power generation (novel power generation system design and low-carbon fuel used for power generation), and building decarbonization (office building energy supply system design). She contributed for the development of SESAME software, which is a novel, system-scale energy analysis tool to assess the system-level greenhouse gas emissions and cost of hundreds of individual energy pathways. Before joining MIT, she worked for Argonne National Laboratory (ANL) on energy conversion system design, TEA, and LCA. She has co-work closely with Department of Energy (DOE) Hydrogen and Fuel Cell Technology Office, Strategic Energy Analysis Center, and Office of Nuclear Energy to evaluate the cost and emissions of multiple decarbonization technologies to supply references for policy and funding decisions. She has taken part in the development of GREET software and has received two Impact Argonne Awards. She holds a PhD in mechanical engineering from the University of Iowa.
