Dr. Uisung Lee is a researcher in the Systems Assessment Group of the Energy Systems Division at Argonne National Laboratory. His expertise mainly focuses on life-cycle analyses (LCAs) of various Waste-to-Energy (WTE) pathways and mid-point impact analysis. WTE pathways that Dr. Lee analyzed include feedstocks such as organic municipal solid waste and sludge from wastewater treatment facilities, which are converted into transportation fuels through biochemical (anaerobic digestion and fermentation) and thermochemical (hydrothermal liquefaction) processes. The WTE pathways were further expanded for the LCAs of other renewable hydrocarbon fuel production such as dimethyl ether (DME) generated from landfill gas or renewable natural gas.
Dr. Lee’s research also covers mid-point impact analyses. He specifically evaluated the regional impact of consumed water for various energy systems, because the impact of the same amount of water consumption may be different by region due to the spatial variation of available water resources. The mid-point impact analysis is a way of interpreting life-cycle inventories by evaluating the potential impacts of an emission or extraction. This analysis is not only limited to water resources but also can be further expanded to other mid-point impact analysis.
