Washington Metropolitan Area Transit Authority: Biodiesel Fuel Comparison Final Data Report
8/15/2002
The West Virginia University measured the exhaust emissions from a Flxible Transit bus with a 1990 Cummins L10 engine operated on standard federal type-1 deisel fuel (D1), ultra-low sulfur type-1 diesel fuel (ULSD1) and on a blend of 20% biodiesel and 80% ULSD1 fuel (BD20). During the ULSD1 and BD20 tests the transit bus was equipped with an Engelhard DPX catalyzed particulate filter. The vehicle was exercised over a chassis dynamometer test cycle that was developed from data logged from WMATA buses during normal passenger service in the Washington D.C. Metropolitan Area. All measurements were made in accordance with the guidelines set forth in the Code of Federal Regulations CFR40 Part 86 Subpart N.

United Parcel Service (UPS) CNG Truck Fleet: Final Results
8/1/2002
In cooperation with UPS, a selection of Freightliner CNG delivery vehicles from the company's original 1996 order were evaluated as part of the U.S. Department of Energy/National Renewable Energy Laboratory (DOE/NREL) Truck Evaluation Project. The plan for this evaluation was to test as many as 15 CNG package delivery cars and 3 diesel package delivery cars operating in the Hartford, Connecticut area from UPS's Waterbury, Hartford, and Windsor facilities. This report included a technical review of data collected for the UPS CNG package delivery car operations in Hartford and Waterbury, Connecticut, compared with UPS diesel truck operations in Windsor, Connecticut. The objective of this project was to provide transportation professionals with quantitative, unbiased information on the cost, maintenance, operational, and emissions characteristics of CNG as one alternative to conventional diesel fuel for heavy-duty trucking applications.

Technical Assessment of Advanced Transit Bus Propulsion Systems
8/1/2002
This report provides the results of a technology assessment developed as part of Phase I of the Dallas Area Rapid Transit (DART) Zero Emission Program (ZEP). The scope of this report explores the advanced propulsion technologies feasible for bus ordering by DART in 2007 (replacing the model year 1998 and prior standard bus fleet) and capable of adequate performance for DART service, while meeting the emissions standards.
Beyond Diesel-Renewable Diesel
8/1/2002
This fact sheet explores domestically produced, renewable fuels such as biodiesel and E-diesel as possible alternatives to conventional diesel and a way to displace some of America's petroleum imports.
Hybrid Electric Transit Buses: New York City Transit (NYCT) Diesel Hybrid Electric Buses: Final Results
7/1/2002
New York City Transit (NYCT), part of the Metropolitan Transportation Authority in New York, began operating the first of 10 heavy-duty diesel hybrid-electric transit bus prototypes (Model VI) from Orion Bus Industries in 1998. All 10 buses were in revenue service by mid-2000. The operating costs, efficiency, emission, and overall performance of these low-floor hybrid buses were compared against those of 14 conventional high-floor diesel transit buses from (NovaBUS Corporation and Orion) operated by NYCT in similar service. The objective of this DOE research project, managed by the National Renewable Energy Laboratory (NREL), was to provide transportation professionals with quantitative, unbiased information on the cost, maintenance, operational, and emission characteristics of diesel hybrid-electric systems as one alternative to conventional diesel engines for heavy-duty transit bus applications.

Battery-Powered Electric and Hybrid Electric Vehicle Projects to Reduce Greenhouse Gas Emissions: A Resource Guide for Project Development
7/1/2002
This report provides national and international project developers with a guide on how to estimate and document the GHG emission reduction benefits and/or penalties for battery-powered and hybrid-electric vehicle projects. This primer also provides a resource for the creation of GHG emission reduction projects for the Activities Implemented Jointly (AIJ) Pilot Phase and in anticipation of other market based project mechanisms proposed under the United Nations Framework Convention of Climate Change (UNFCC). Though it will be necessary for project developers and other entities to evaluate the emission benefits of each project on a case-by-case basis, this primer will provide a guide for determining which data and information to include during the process of developing the project proposal.
General Evaluation Plan: Fleet Test & Evaluation Projects
7/1/2002
The National Renewable Energy Laboratory (NREL) Fleet Test and Evaluation (FT&E) team was formed to accomplish the objectives of U.S. Department of Energy's (DOE) current and emerging programs. Composed of NREL and Battelle personnel, the team supports vehicle test project initiated by DOE's Office of FreedomCAR and Vehicle Technologies (OFCVT) and the Office of Hydrogen, Fuel Cells, and Infrastructure Technologies (OHFCIT). FT&E projects help fleet owners and operators facilitate purchase decisions by providing them with comprehensive laboratory and fleet test data on viable alternative fuel vehicles (AFVs) and advanced technology vehicles (ATVs). ATVs include hybrid electric and fuel cell vehicles.
Diesel Emissions Control-Sulfur Effects Project (DECSE) - Summary of Reports
6/1/2002
Testing conducted by Diesel Emissions Control-Sulfur Effects (DECSE) project was designed to provide data on effects of various levels of sulfur in diesel fuels on emission control systems. Fuel composition affects engine efficiency, chemical composition of the exhaust, and the amount of a given pollutant or proportions of types of pollutants. This report summarizes the results of testing of diesel particulate filters, lean-NOx catalysts, diesel oxidation catalysts, and NOx adsorber catalysts.

The Congestion Mitigation and Air Quality Improvement Program: Assessing 10 Years of Experience
6/1/2002
The Congestion Mitigation and Air Quality Improvement (CMAQ) program was enacted as part of the Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991 and reauthorized by the Transportation Equity Act for the 21st Century (TEA-21) of 1998. After nearly a decade of the program's operation, congressional sponsors were interested in knowing whether it has been effective and whether its projects were cost-effective relative to other strategies for reducing pollution and congestion. Their questions were summarized in a request to the National Academy of Sciences for a study to evaluate the CMAQ program.

Lignocellulosic Biomass to Ethanol Process Design and Economics Utilizing Co-Current Dilute Acid Prehydrolysis and Enzymatic Hydrolysis For Corn Stover
5/30/2002
The U.S. Department of Energy (DOE) is promoting the development of ethanol from lignocellulosic feedstocks as an alternative to conventional petroleum-based transportation fuels. DOE funds both fundamental and applied research in this area and needs a method for predicting cost benefits of many research proposals. To that end, the National Renewable Energy Laboratory (NREL) has modeled many potential process designs and estimated the economics of each process during the last 20 years. This report is an update of the ongoing process design and economic analyses at NREL. We envision updating this process design report at regular intervals; the purpose being to ensure that the process design incorporates all new data from NREL research, DOE funded research and other sources, and that the equipment costs are reasonable and consistent with good engineering practice for plants of this type. For the non-research areas this means using equipment and process approaches as they are currently used in industrial applications.
