Uisung Lee

Energy Systems Analyst


Dr. Uisung Lee is an energy systems analyst in the Systems Assessment Center of the Energy Systems Division at Argonne National Laboratory. His expertise mainly focuses on conducting life-cycle analyses (LCAs) of various energy systems to evaluate the environmental impacts such as life-cycle greenhouse gas emissions, fossil fuel use, air pollutant emissions, and water consumption. The systems include but not limited to waste-to-energy (WTE) pathways, sustainable aviation fuel pathways, and marine fuel pathways. He supports the development of GREET (The Greenhouse gases, Regulated Emissions, and Energy use in Transportation) model, an LCA model developed by Argonne that is structured to systematically examine the life-cycle energy use and emissions with a wide. In addition, Dr. Lee’s research also covers regional and seasonal water stress analysis of energy systems such as hydrogen production, electricity generation, and algal biofuel production using a water stress index, AWARE-US, developed by Argonne that considers regional and seasonal water availability in U.S. counties. He is a nominated expert to the International Civil Aviation Organization’s (ICAO) Fuels Task Group (FTG) for evaluating core LCA values of aviation fuels. His recent research focuses on analyzing the environmental impact of CO2 utilization which converts waste gas into valuable products such as ethanol and chemicals.

Areas of Expertise

  • Evaluation of energy and environmental impacts of various energy systems (waste-to-energy pathways, sustainable aviation fuels, marine fuels, CO2 utilization, batteries, biopower)
  • Regional/seasonal water stress analysis using AWARE-US (hydrogen fuel cell vehicles, electricity generation, algal biofuel production)
