SuperShuttle CNG Fleet Study Summary
3/1/2001
In March 1999, the Office of Technology Utilization's Field Operations Program began a fleet evaluation of CNG vans in the SuperShuttle fleet in Boulder, Colorado. The results for the evaluation were positive and the fleet is considering adding more alternative fuel vehicles in the future. This fact sheet summarizes the details of the study.

State Alternative Fuel Vehicle Incentives: A Decade and More of Lessons Learned
2/1/2001
This report assesses the effectiveness of state incentives and suggests incentives that might encourage new vehicle technologies. It does not assess whether a state should promote alternative fuel vehicles or whether such vehicles are the most effective means to reduce air pollution. Rather, the analysis analyzes the effectiveness of state incentives of the past decade and describes the characteristics of effective alternative fuel vehicle incentives and the fiscal implications for a state that is committed to support an effective alternative fuel vehicle program.

Waste Management LNG Truck Fleet Alternative Fuel Truck Evaluation Project: Final Results
1/1/2001
Waste Management, Inc. a private company based in Houston, Texas, began operating a fleet of heavy-duty refuse trucks powered by liquefied natural gas (LNG) at it Washington, Pennsylvania facility in 1997. Waste Management currently operates seven LNG refuse trucks at that site. The U.S. Department of Energy (DOE) Office of Heavy Vehicle Technologies sponsored a research project to collect and analyze data on the performance and operation costs of five Waste Management's LNG trucks in commercial service, for comparison with data on the performance of three diesel trucks operating on similar routes. This report presents an evaluation of five of the first seven LNG trucks produced by Mack. Mack partnered with Waste Management in Washington, Pennsylvania, to field test its natural gas engine design and gain experience.

SuperShuttle CNG Fleet Evaluation: Final Report
10/1/2000
SuperShuttle originated in Los Angeles in 1983 as a shuttle service that focused on shared ride door-to-door airport passenger service. The company currently services 23 airports, with 1,000 vehicles transporting more than 20,000 passengers each day. SuperShuttle has been operating in Colorado since mid 1996, serving the local community and Denver International Airport (DIA). Their fleet of 85 vehicles includes 18 AFVs, fueled by both liquefied petroleum gas (LPG) and compressed natural gas (CNG). For this project, data was collected from 13 passenger vans operating in the Boulder/Denver, Colorado, area. The study vehicles were all 1999 Ford E-350 passenger vans based at SuperShuttle's Boulder location. Five of the vans were dedicated CNG, five were bi-fuel CNG/gasoline, and three were standard gasoline vans that were used for comparison.

On the Road in 2020: A Life-cycle Analysis of New Automobile Technologies
10/1/2000
This report is a description of work done at MIT during the past two years to assess technologies for new passenger cars that could be developed and commercialized by the year 2020. The report does not make predictions about which technologies will be developed nor judgments about which technologies should be developedissues for the marketplace and for public policy that are not examined here.
The primary motivation for this study was the desire to assess new automobile technologies which have the potential to function with lower emissions of greenhouse gases (GHGs) widely believed to contribute to global warming. The GHG of most concern here is carbon dioxide (CO2), but methane (CH4) and nitrous oxide (N2O) can also be important. If public policy or market forces result in constraints on GHG emissions, automobiles and other light-duty vehiclesa key part of the transportation sectorwill be candidates for those constraints since the transportation sector accounts for about 30% of all CO2 emissions in OECD countries, and about 20% worldwide.

Waste Management LNG Truck Fleet Final Data Report
8/1/2000
Waste Management, Inc., based in Houston, Texas, is the largest waste management service company in North America. This report addresses activities at one of Waste Management's facilities in Washington, Pennsylvania, south of Pittsburgh. This site has been operating seven heavy duty LNG refuse trucks (Mack trucks with E7G engines) with the first LNG truck starting operation in August 1997. The following document describes the results of data collection and evaluation of five of the seven heavy-duty LNG refuse trucks compared to three similar heavy-duty diesel refuse trucks operating in the Washington, Pennsylvania area.
Heavy-Duty Truck Demonstration with a 400-HP DDC Series 60G LNG Engine, and Support for the Downtown Los Angeles LNG Station
6/9/2000
The Trucking industry has taken an active interest in the use of engines powered by liquefied natural gas (LNG) to reduce NOx and PM emissions. However, major barriers exist to widespread use of LNG in trucking applications, including reduced performance and higher initial capital costs compared to diesel-fueled vehicles, as well as a limited fueling infrastructure. To help address these barriers, the National Renewable Energy Laboratory, with funding from the U.S. Department of Energy, joined with the South Coast Air Quality Management District (SCAQMD)to contract with a team led by the San Jose Transportation Technology Group of ARCADIS Geraghty & Miller. The focus of the contract was to upgrade a Detroit Diesel Corporation (DDC) Series 60G (S60G) engine for increased power and torque, and demonstrate this engine in an LNG-fueled semi-tractor.
Limited Progress in Acquiring Alternative Fuel Vehicles and Reaching Fuel Goals
2/1/2000
with the first deadline approaching for EPAct's petroleum replacement goals the GAO was asked to review progress towards achieving EPACT goals. gao was asked to determine the progress made in acquiring alternative fuel vehicles and using altnerative fuels to meeting the act's fuel replacement goals. Also, GAO determined the impediments to using alternative fuel vehicles and the measures that can be taken to address those impediments in order to reach the act's replacement goals.
Alternative Fuel Case Study: UPS Delivers with Alternative Fuels
8/1/1999
This four-page fact sheet discusses how the United Parcel Service has integrated alternative fuel vehicles, specifically CNG vehicles, into their fleets. UPS has operated its service with many different kinds of AFVs since the early 1930s. The fact sheet also discusses the different types of alternative fuels and the types of AFVs UPS has incorporated into their fleets.
