Effects of nitrogen fertilizer on the ethanol fuel system

Abstract

Ethanol is used as a substitute transportation fuel for gasoline in two ways: E10 (a mixture of 10 vol % ethanol and 90 vol % gasoline) and E85 (a mixture of 85 vol % ethanol and 15 vol % gasoline). Using ethanol derived from corn grain as liquid fuel would reduce nonrenewable energy and greenhouse gas emissions, but would increase acidification, eutrophication and photochemical smog, compared to using gasoline as liquid fuel, if current practices remain unchanged (primarily agricultural practices). The effects of nitrogen fertilizer application on the bioethanol fuel system were studied. To estimate local soil carbon and nitrogen dynamics in biomass cultivation, the DAYCENT model was used, which is the daily time step version of the CENTURY model, a multicompartmental ecosystem model. The system boundary includes corn production, transportation of corn to a dry mill, the dry mill processing steps, transportation of ethanol to users, ethanol fueled vehicle operation, and upstream processes. The effects of planting winter cover crops on the bioethanol fuel system were examined. The potential impact categories considered were nonrenewable energy consumption, greenhouse gas emissions, photochemical smog, acidification, and eutrophication. This is an abstract of a paper presented at the AIChE Annual Meeting (Salt Lake, UT 11/4-9/2007).
