City and County of Denver: Technical comparison between hythane, CNG and gasoline fueled vehicles

PDF Version Also Available for Download.

Description

The City and County of Denver, in cooperation with the Urban Consortium Energy Task Force of Public Technology, Inc. has completed a unique two-year research and development project designed to test and compare the technical merits of three transportation fuels. Comparisons of the tailpipe emissions from Hythane - a new, blended, alternative motor fuel comprised of 85% compressed natural gas (CNG) and 15% hydrogen measured by volume - to the emissions from gasoline and 100% CNG were conducted. This project has been one of the first pioneering studies of a hydrogen blended fuel and, through its success, has prompted eight ... continued below

Description

The City and County of Denver, in cooperation with the Urban Consortium Energy Task Force of Public Technology, Inc. has completed a unique two-year research and development project designed to test and compare the technical merits of three transportation fuels. Comparisons of the tailpipe emissions from Hythane - a new, blended, alternative motor fuel comprised of 85% compressed natural gas (CNG) and 15% hydrogen measured by volume - to the emissions from gasoline and 100% CNG were conducted. This project has been one of the first pioneering studies of a hydrogen blended fuel and, through its success, has prompted eight additional Hythane research projects to date. Phase I of the project provided results from the Federal Test Procedure (FTP) testing of a light duty pick-up truck operating on Hythane. The purpose of this testing was to quantify any decrease in tailpipe emissions and to determine whether Hythane could meet the California Ultra Low Emission Vehicle standard (ULEV) for light duty trucks. During Phase I, FTP analyses were conducted in both Colorado (high altitude testing) and California (sea level testing) on a converted Chevrolet S-10, pick-up truck by Hydrogen Consultants (HCl), the Colorado Department of Health (CDH) and the California Air Resource Board (CARB). Currently, the only other non-electric vehicle which is capable of meeting the ULEV standard is Chrysler`s natural gas vehicle. There was additional interest in the role Hythane could play as a transitional fuel in the introduction of hydrogen. Hydrogen, a renewable energy carrier, may soon be categorized as a ZEV fuel by the South Coast Air Quality Management District. This factor may encourage the use of Hythane as a transportation fuel that not only meets the ULEV standard, but may provide the bridge necessary to the eventual widespread use of hydrogen.
