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.

Clean Cities Alternative Fuel Price Report
5/1/2000
The Clean Cities Alternative Fuel Price Report provides regional alternative and conventional fuel prices for biodiesel, compressed natural gas, ethanol, hydrogen, propane, gasoline, and diesel. The Alternative Fuel Price Report is a snapshot in time of retail fuel prices. Alternative fuel fleets can obtain significantly lower fuel prices than those reported by entering into contracts directly with local fuel suppliers.
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.

Urban Waste Grease Resource Assessment
11/1/1998
This study collected and analyzed data on urban waste grease resources in 30 randomly selected metropolitan areas in the U.S. Two major categories of urban waste grease were considered, including yellow grease feedstock collected from restaurants by rendering companies, and grease trap wastes from restaurants.

Alternative Fuel Vehicles: Real-World Perspectives from the Federal Fleet
7/1/1998
Vehicles that run onfuels other than gasoline, or "alternative fuel" vehicles (AFVs), offer great promise for improving air quality and lessening our nation's dependence on imported oil. But if they are to fulfill this promise and replace traditional gasoline vehicles on a large scale, they must meed the needs of the people using them, and consumers must have access to"real-world" information about them. Do they drive as well as gasoline vehicles? Are their refueling stations as convenient as the corner gas station? Can we expect the same reliability that we've come to expect from our gasoline vehicles? How better to answer these questions than to ask the people who are actually running the AFVs? So in 1996, the National Renewable Energy Laboratory (NREL), a U.S. Department of Energy (DOE) national labortory, designed a nationwide study to capture the opinions of federal fleet managers and drivers onthe performance, reliability, driveability, and acceptability of AFVs. NREL put together this short brochure to serve as a "quick look" summaryof the surveys and their results.
