Fuel and Fuel Additive Registration Testing for Ethanol-Diesel Blend for O2Diesel, Inc.
2/1/2004
Testing was performed on a heavy-duty diesel engine in support of the Environmental Protection Agency (EPA) requirements for registration of designated fuels and fuel additives as stipulated by sections 211(b) and 211(e) of the Clean Air Act. Emission generation, collection, and analysis of the regulated emissions and speciation of vapor-phase and semi-volatile hydrocarbon compounds were performed on a Detroit Diesel Series 60 engine manufactured in 2002 and meeting the 1998 federal heavy-duty emission standards that applied in 2002.

State-Level Workshops on Ethanol for Transportation
1/31/2004
In 2002/2003, under contract to the National Renewable Energy Laboratory, BBIInternational conducted state-level workshops ethanol in Hawaii, Nevada, Kentucky and California. These four workshops followed over 30 other workshops previous held under the Ethanol Workshop Series program sponsored by the U.S. Department of Energy. Two other workshops were conducted by BBI International during 2003, Oklahoma and Kansas, under contract to the Western Regional Biomass Energy Program.The Ethanol Workshop Series (EWS) was intended to provide a forum for interest groups to gather and discuss what needs to be accomplished to facilitate ethanol production in-state using local biomass resources. In addition, the EWS was to provide a promotional and educational forum for policy makers, community leaders, media and potential stakeholders. It was recognized that to eventually achieve biomass-ethanol production, it was necessary to supportgrain-ethanol production as a bridge.The long-term goal of the Workshops was to facilitate the development of biomass ethanol plants at a state-level. The near-term goal was to provide correct and positive information for education, promotion, production and use of fuel ethanol. The EWS drew from 65 to over 200 attendees and were deemed by the local organizers to have served the objectives set out by the U.S. Department of Energy.

Biomass Power and Conventional Fossil Systems with and without CO2 Sequestration--Comparing the Energy Balance, Greenhouse Gas Emissions and Economics
1/31/2004
Power generation emits significant amounts of greenhouse gases (GHGs), mainly carbon dioxide (CO2). Sequestering CO2 from the power plant flue gas can significantly reduce the GHGs from the power plant itself, but this is not the total picture. CO2 capture and sequestration consumes additional energy, thus lowering the plant's fuel-to-electricity efficiency. To compensate for this, more fossil fuel must be procured and consumed to make up for lost capacity. Taking this into consideration, the global warming potential (GWP), which is a combination of CO2, methane (CH4), and nitrous oxide (N2O) emissions, and energy balance of the system need to be examined using a life cycle approach. This takes into account the upstream processes which remain constant after CO2 sequestration as well as the steps required for additional power generation.

Production of Butyric Acid and Butanol from Biomass
1/1/2004
Butanol was used to replace gasoline gallon for gallon in a 10,000 mile trip across the U.S. without the need to highy modify a 1992 Buick. Butanol can now be made for less than ethanol and yields more BTUs from the same corn, making the plow-to-tire equation positive. Butanol when substituted for gasoline gives better gas mileage and does not pollute the atmosphere.

Roadmap for Agriculture Biomass Feedstock Supply in the United States
11/30/2003
The Biomass Research and Development Technical Advisory Committee set forth a goal that biomass will supply 5% of the nation's power, 20% of transportation fuels, and 25% of chemicals by 2030. These combined goals are approximately equivalent to 30% of the current petroleum consumption. The benefits of a robust biorefinery industry supplying this amount of domestically produced power, fuels, and products is considerable, including decreased demand for imported oil, revenue to the depressed agriculture industry, and revitalized rural economies. A consistent supply of high quality, low cost feedstock is vital in achieving this goal. This biomass roadmap defines the research and development path towards supplying the feedstock needs of the biorefinery and achieving the important national goals set for biomass.

Safety and Performance Assessment of Ethanol/Diesel Blends (E-Diesel)
9/1/2003
In this study, TIAX performed a failure mode and effects analysis (FMEA) to evaluate the relative safety risks and performance risks of E-diesel use compared to standard diesel fuel use. The fuel use process evaluated included the preparation, transportation, fleet vehicle fueling station storage, and use of E-diesel. Only the use of E-diesel fuel containing up to 15% ethanol in heavy-duty vehicle fleets was evaluated.

Fuel-Cycle Energy and Emission Impacts of Ethanol-Diesel Blends in Urban Buses and Farming Tractors
7/30/2003
About 2.1 billion gallons of fuel ethanol was used in the United States in 2002, mainly in the form of gasoline blends containing up to 10% ethanol (E10). Ethanol use has the potential to increase in the U.S. blended gasoline market because methyl tertiary butyl ether (MTBE), formerly the most popular oxygenate blendstock, may be phased out owing to concerns about MTBE contamination of the water supply. Ethanol would remain the only viable near-term option as an oxygenate in reformulated gasoline production and to meet a potential federal renewable fuels standard (RFS) for transportation fuels. Ethanol may also be blended with additives (co-solvents) into diesel fuels for applications in which oxygenation may improve diesel engine emission performance.Numerous studies have been conducted to evaluate the fuel-cycle energy and greenhouse gas (GHG) emission effects of ethanol-gasoline blends relative to those of gasoline for applications in spark- ignition engine vehicles (see Wang et al. 1997; Wang et al. 1999; Levelton Engineering et al. 1999; Shapouri et al. 2002; Graboski 2002). Those studies did not address the energy and emission effects of ethanol-diesel (E-diesel or ED) blends relative to those of petroleum diesel fuel in diesel engine vehicles. The energy and emission effects of E-diesel could be very different from those of ethanol-gasoline blends because (1) the energy use and emissions generated during diesel production (so-called "upstream" effects) are different from those generated during gasoline production; and (2) the energy and emission performance of E-diesel and petroleum diesel fuel in diesel compression-ignition engines differs from that of ethanol-gasoline blends in spark-ignition (Otto-cycle-type) engine vehicles.The Illinois Department of Commerce and Economic Opportunity (DCEO) commissioned Argonne National Laboratory to conduct a full fuel-cycle analysis of the energy and emission effects of E-diesel blends relative to those of petroleum di

The Effect of Biodiesel Composition on Engine Emissions from a DDC Series 60 Diesel Engine
2/28/2003
Certificaation fuel runs exhibited a mean NOx emission level of 4.59 g/bhp-h (+/-.053) with no significant drift over the four month test program. PM emissions averaged 0.261 g/bhp-h (+/-0.019). A small downward drift in PM emissions was evident (11% over the course of the project). Thus, no correction for drift was applied to the NOx emissions data but a small correction wass applied to PM.
