Clean Fuels Paving the Way for America's Future: A Source for Information on Clean Burning Alternative Transportation Fuels
4/1/1995
With so many alternative fuels being promoted by various groups, it is important for legislators, the public and all interested parties to understand the different fuels that are available, how they are made, how they are used and their impact on the environment. This brochure is intended to help legislators at all levels to make informed decisions and for the media, with a responsibility of informing the public, to be educated on these issues. The fuels covered in this brochure include: ethanol, ethyl tertiary butyl ether, methanol, methyl tertiary butyl ether, biodiesel, gasoline additives and combustion modifiers, electric vehicles, natural gas and propane. It also summarizes regional and state clean fuel policies and regulations.

Results of Combustion and Emissions Testing when Co-Firing Blends of Binder-Enhanced Densified Refuse-Derived Fuel (b-dRDF) Pellets and Coal in a 440 MW, Cyclone Fired Combustor
7/30/1994
This research project characterized the effects o f burning a combination of binder-enhanced densified refusederived fuel (b-dRDF1 pellets and coal in a commercial-scale electrical generating facility. Pelletized b-dRDF has been burned in coal combustors, but only in quantities of Jess than 3% in large utility systems. This research investigated using b-dRDF in quantities up t o 20%. Through this research, project participants gained operating, technical, and economic viability data that will be critical for the near-term commercial use of b-dRDF.

Notes: This report contains the test data from the co-firing of b-dRDF pellets and coal in a MO-MW, cyclone- fired combustor. These tests were conducted under a Cooperative Research and Development Agreement (CRADA). The CRADA partners included the U.S. Department of Energy (DOE); the National Renewable Energy Laboratory (NREL); Argonne National Laboratory (ANL); Otter Tail Power Company; Green Isle Environmental, Inc.; XL Recycling Corporation; and Marblehead Lime Company. The report. is made up of three volumes. Volume 1 contahs a description of the test facility, the test program, test results, and study conclusions and recommendations; Volume 2 contains the field data and laboratory analysis of each individual run. Volume 3 contains other supporting information, quality assurance documentation, and safety and test plans. This multi-volume approach enables readers to find information at the desired level of detail, depending on individual interest or need.
Impacts of Alternative Fuels on Air Quality
6/1/1994
The objective of this project was to determine the impact of alternative fuels on air quality, particularly ozone formation. The alternative fuels of interest are methanol, ethanol, liquefied petroleum gas, and natural gas. During the first year of study, researchers obtained qualitative data on the thermal degradation products from the fuel-lean (oxidative), stoichiometric, and fuel-rich (pyrolytic) decomposition of methanol and ethanol. The thermal degradation of ethanol produced a substantially larger number of intermediate organic by-products than the similar thermal degradation of methanol, and the organic intermediate by-products lacked stability. Also, a qualitative comparison of the UDRI flow reactor data with previous engine test showed that, for methanol, formaldehyde and acetone were the organic by-products observed in both types of tests; for ethanol, only very limited data were located.

How Much Energy Does It Take to Make a Gallon of Soydiesel?
1/1/1994
Is more energy used to grow soybean feedstock and to process it into soydiesel than is contained in soydiesel fuel itself? This study addresses this question. This report concludes that soydiesel production in the United States is a net energy generator. Even under a worst case scenario, more energy is contained in esterified soybean oil and its co-products - glycerine and soy meal - than is used to grow the soybean crop and process it into soydiesel fuel and associated products. If soybean is grown as a rotation crop with corn using state of the art farm practices as much as four times the energy input can be realized from the various products generated.
