| US DOE - US Department of Energy | - 1. A Full Fuel-Cycle Analysis of Energy and Emissions Impacts of Transportation Fuels Produced from Natural Gas
This study reveals that, in general, the use of natural gas-based fuels reduces energy use and emissions relative to use of petroleum-based gasoline and diesel fuel, although different natural gas-based fuels in different vehicle technologies can have significantly different energy and emissions impacts. - 1. Facts about CNG and LPG Conversions
Office of Transportation Technologies, DOE. - 1. Just the Basics: Fuel Cells - Transportation for the 21st Century
A fuel cell harnesses the chemical energy of hydrogen and oxygen to generate electricity without combusion or pollution. The only byproducts are pure water and useful heat. - 1. Pierce Transit, Tacoma, Washington, US
In 1986, the Pierce County Transportation Benefit Area Authority (Pierce Transit), based in Tacoma, Washington, made a commitment to the future of the transportation industry and to the environment by deciding to put buses powered by compressed natural gas (CNG) into everyday service. Eleven years, 72 CNG buses, and countless curious inquiries later, CNG is no longer a novelty it s business as usual. - 1. The Technical Background of Hybrid Electric Vehicles
Hybrid Electric Vehicles (HEVs) combine two or more energy conversion technologies (e.g., heat engines, fuel cells, generators, or motors) with one or more energy storage technologies (e.g., fuel, batteries, ultracapacitors, or flywheels). - 11. Rogue Valley Transport District, Rogue Valley, Oregon, US
The increasingly urbanized region served the Rogue Valley Transportation District (RVTD), home to nearly 130,000 people and situated in a valley at the convergence of the Cascade and Siskiyou mountain ranges in southwest Oregon, faces a continuing challenge to maintain air quality because of the local air shed's susceptibility to terrain-induced temperature inversions. - 12. Antelope Valley School Buses
Located about 70 miles northeast of Los Angeles, the Antelope Valley Schools Transportation Agency (AVSTA) operates a fleet of school buses and special-education vans that transport students in four school districts covering 1,700 square miles. - 13. Sun Metro, El Paso, Texas, US
Sun Metro, the public transportation authority of El Paso, Texas, operates the world s largest natural-gas-fueled mass transit fleet. Approximately 53% of Sun Metro's fleet of 240 vehicles - buses, paratransit vehicles, and support vehicles - runs on natural gas. - 17. Pierce Transit, Tacoma, Washington, US
In 1986, the Pierce County Transportation Benefit Area Authority (Pierce Transit), based in Tacoma, Washington, made a commitment to the future of the transportation industry and to the environment by deciding to put buses powered by compressed natural gas (CNG) into everyday service.

- 5. Distributed Hydrogen Fueling Systems Analysis
Directed Technologies Inc. has analyzed the costs and other attributes of three fuel infrastructure systems to support fuel cell vehicles: hydrogen, methanol and gasoline. This work compliments previous DTI analyses of onboard fuel system costs for these three fuels B onboard hydrogen storage systems in the case of hydrogen, and onboard fuel processors for methanol and for gasoline. - 5. Is Clean Diesel Fuel an Option for Developing Countries?
- 6. Alternatives to Traditional Transportation Fuels
Petroleum-based gasoline and diesel fuel account for nearly all of the fuel used in onroad vehicles today. Concerns about the environmental effects of fossil fuel use and the Nation s dependence on foreign oil are providing the impetus for increasing use of alternativefueled vehicles (AFV s) and alternatives to traditional transportation fuels. - 7. DOE Hybrid Electric Vehicle Program ... Why HEVs?
The development goals for this progressive technology include emissions reduction, while obtaining superior fuel economy, as well as the flexibility of using either petroleum or alternative fuels. - Alternative Fuel Vehicle Fleet Buyer's Guide
The Vehicle Buyer's Guide for Fleets is designed to educate fleet managers and policy makers about alternative fuels and vehicles and help them determine whether the Energy Policy Act of 1992 (EPAct) affects them. Use the site to figure if your fleet is covered under EPAct, obtain pricing and technical specifications for light- and heavy-duty AFVs, find an alternative fueling station in your area, or research information about state AFV purchasing incentives and laws. - Clean Cities Program
The U.S. Department of Energy's Clean Cities Program supports public-private partnerships that deploy alternative fuel vehicles and build supporting alternative fuel infrastructure. - Diesel Emission Control - Sulfur Effects (DECSE) Program - Final Report: Diesel Oxidation Catalysts and Lean-NOx Catalysts
The Diesel Emission Control - Sulfur Effects (DECSE) Program is a joint government/industry program which aims to determine the impact of diesel fuel sulfur levels on emission control systems whose use could lower emissions of nitrogen oxides (NOx) and particulate matter (PM) from on-highway trucks from the 2002-2004 model years.
