Life cycle emissions vary between 1.5 and 22 gCO2eq./MJ ethanol (2011 design) depending on production location (98% to 77% reduction vs. gasoline). Using system expansion for co-product allocation, ethanol production in studied locations meet the Energy Independence and Security Act emissions requirements for cellulosic biofuels; however, regional factors and on-going technology developments significantly influence these results.
Keywords: Life Cycle Assessment, Corn Stover, EthanolHighlights: We evaluate the impacts of regional parameters and technology development on the life cycle greenhouse gas emissions of corn stover-derived ethanol The impacts of corn stover removal on soil carbon stocks and N2O emissions are the dominant regionally-dependent parameters Biorefinery emissions based on the 2011 NREL design model are approximately double that of the preceding 2002 NREL model due to inclusion of greenhouse gas-intensive inputs (caustic, ammonia, glucose) For all regions and process design models considered, corn-stover derived ethanol would meet the emissions reduction threshold of the US Energy Independence and Security Act when system expansion is used for co-product allocation.3
