A Journal of Industrial Ecology article outlines the research, conducted by an interdisciplinary team of UNL researchers, which evaluated dry-mill ethanol plants that use natural gas. Such plants account for nearly 90 percent of current production capacity. This research is the first to quantify the impact of recent improvements throughout the corn-ethanol production process, including crop production, biorefinery operations and co-product use, said Ken Cassman, UNL agronomist who was part of the research team. Previous studies, which found ethanol to have a much smaller edge over gasoline in GHG emissions, relied on estimates based on corn production, ethanol plant performance and co-product use as they were seven years ago. "Critics claim that corn ethanol has only a small net energy yield and little potential for direct reductions in GHG emissions compared to use of gasoline," Cassman said. "This is the first peer-reviewed study to document that these claims are not correct." More recently built -- and more efficient -- plants now represent about 60 percent of total ethanol production and will account for 75 percent by the end of 2009, Cassman added. These newer biorefineries have increased energy efficiency and reduced GHG emissions through the use of improved technologies. Also, many are located near cattle feeding or dairy operations, which allows efficient use of the co-product distillers grains as cattle feed. For example, the distillers grains don't have to be dried to facilitate long-distance travel; drying uses up to 30 percent of total energy use in the ethanol plant. Also contributing to corn ethanol's GHG performance are improvements in how the crop is grown, including improved crop and soil management, and better hybrids that help farmers achieve a steady increase in corn yields without having to increase fertilizer or energy inputs. The result of these improvements: The ethanol industry currently is producing a fuel that is 48 to 59 percent lower in direct-effect lifecycle greenhouse gas emissions than gasoline. That's two to three times the reduction reported in earlier studies that did not take into account recent advances in corn-ethanol production. The net energy ratio, which averaged 1.2 to 1 in earlier studies, is 1.5-1.8 to 1 in the recent research, Cassman said. That means that for every unit of energy it takes to make ethanol, 1.5 to 1.8 units of energy are produced as ethanol. Even more striking is the corn ethanol's potential to replace oil. This new study estimates that 10-19 gallons of ethanol are produced for every gallon of petroleum used in the entire corn-ethanol production life cycle. The range in the ethanol-oil replacement value, as well as the ranges measured for net energy efficiency and GHG emissions reduction, are due to differences in crop management practices and ethanol plant performance. The findings are key to corn ethanol's long-term viability, Cassman said, because the industry has been justified, in part, by the assumption that GHG emissions would be reduced as ethanol replaces petroleum-derived gasoline. The research is a component of a regional, multi-university research initiative known as NC506, to assess the economic and environmental sustainability of the rapidly expanding Midwestern corn ethanol industry. This project is funded by the U.S. Department of Agriculture and the North Central Bioeconomy Consortium. Other sources of funding include the Western Governors Association, Environmental Defense, and the Agricultural Research Division at UNL, and the Nebraska Center for Energy Sciences Research. Researchers used the UNL-developed Biofuel Energy Systems Simulator, or BESS, to make their calculations. This software is available for download at http://www.bess.unl.edu . BESS analyzes energy yield and efficiency, greenhouse gas emissions and resource requirements for individual biofuel production systems. This "seed-to-fuel" tool quantifies lifecycle carbon savings and environmental impact of individual biofuel systems. It factors in energy use and greenhouse gases from crop production, ethanol conversion, co-product use, and transportation. The study did not take into account indirect land use change, because there is not yet a scientific consensus about how to estimate the magnitude of these effects as a component of the greenhouse gas intensity of biofuels. ?2009 Governors' Biofuels Coalition.

Our spring BioDiesel/Clean Diesel workshop is coming up! Please attend or encourage an associate with an interest in these topics to spend two days at Wake Tech, March 3, 4 2009. The sessions will begine at 8:30 and end at 4:30. Format: 15 hours of classroom and hands on presentation to be held at Wake Technical CC Abstract of presentation: The workshop will be divided into two sections. Section 1: The production of BioDiesel. We will begin by describing the nature of tri-glycerides, fatty acids, methyl esters, etc. After introducing these basic concepts, the class will move to the lab where they will participate in the trans-esterification of 25 gallons of WVO utilizing equipment already owned and used by Wake Tech. The class will move in and out of the lab through the duration of the workshop as the production process continues through mixing, settlement, glycerin removal, water washing, etc. While in class we will also cover ASTM testing protocols and various quality and usage issues. Section 2: Clean Diesel/Common Rail Technology. This section will introduce the participants to the functional description of high pressure common rail systems, including high pressure delivery pumps, Piezo Injectors, advanced engine management systems and emission after-treatment system including Diesel Particulate Filters and Selective Catalytic Reduction NOx Converters. Practices that ensure the successful use of Bio Diesel with these late model technologies will be emphasized. Intended audience-- anyone with an interest in the topic may attend, course is directed toward those with an interest in producing BioDiesel and Diesel Technicians. Sponsor: The Continuing Education Division of Wake Tech. Cost: $60.00 (Where else can you beat that price?)

John Bonitz Pittsboro, NC ~~~~~~~~~~~~~ Research Finds Ethanol Production Is More Efficient with Fewer Emissions A report published in Yale's Journal of Industrial Ecology finds corn-ethanol systems have a far greater potential to reduce GHG emissions and U.S. dependence on foreign oil for transportation fuels than prior studies have suggested. The report, Improvements in Life Cycle Energy Efficiency and Greenhouse Gas Emissions of Corn-Ethanol , was a project of the University of Nebraska-Lincoln's Nebraska Center for Energy Sciences Research. New technologies that improve energy efficiency at bio-refineries, environmentally friendly soil management, and co-product utilization are listed as major factors for the lower emissions rate. The study found ?direct effect GHG emissions were estimated to be equivalent to a 48% to 59% reduction compared to gasoline, a two-fold to three- fold greater reduction than reported in previous studies.?
