When determining how much a fuel reduces greenhouse gas emissions as compared to pure gasoline, most use Argonne National Laboratory’s GREET Life-cycle model (Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation Model). In recent years, the model has seen some advancements and during the recent ACE Ethanol Conference, Dr. Jeongwoo Han, assistant energy system analyst with Argonne National Labs, discussed these changes.
As he explained, GREET has been updated and used to evaluate/update the environmental impacts of ethanol. Han’s presentation discussed the recent life-cycle analysis results of ethanol with the technology advancement as well as key issues in life-cycle analysis.
