The carbon intensity (CI) of corn ethanol—i.e., the greenhouse gas emissions produced via the production of a volume of the fuel—is declining, while the average CI of gasoline produced from petroleum sources is gradually increasing, according to a recent report prepared by Life Cycle Associates, LLC for the Renewable Fuels Association (RFA).

Similar trends have been found with regard to fossil energy benefits for the five bioethanol pathways. Corn Ethanol Key conclusions • Corn grain ethanol has a slightly positive net energy on average, but is very dependent on – Ethanol production efficiency – Location and practices in corn production – Transportation distances • Improved corn yield, conversion and purification technology can help, but most gains are incremental 2017-01-12 · In Washington, Agriculture Secretary Tom Vilsack announced the release of a report studying the lifecycle greenhouse gas (GHG) balance of corn ethanol.The report, A Life-Cycle Analysis of the Greenhouse Gas Emissions of Corn-Based Ethanol, finds that GHG emissions associated with corn-based ethanol in the United States are about 43 percent lower than gasoline when measured on an energy GHG Emission Sources for Corn Ethanol 6 10 g 14 g 4 g 31 g 4 g 1 g 9 g Corn Ethanol: 60 g CO2e/MJ (DGS Credit: -13) Fertilizer Production Fertilizer N2O Farming Ethanol Production T&D Combustion LUC From Wang et al.

Abstract. Corn ethanol plants generate high-purity carbon dioxide (CO2) while producing ethanol. If that CO2 could be converted into ethanol by carbon capture and utilization technologies it would be possible to increase ethanol production more than 37% without additional corn grain inputs.
