Des Moines Metropolitan Transit Authority to Convert Diesel Buses to O2Diesel™ Through CityHome™ Program

NEWARK, DE -- (MARKET WIRE) -- July 6, 2005 -- O2Diesel Corporation (AMEX: OTD) today announced that the Des Moines Metropolitan Transit Authority (MTA) has joined the CityHome™ program. CityHome is a major national clean air initiative designed to create a better quality of life for city residents by improving urban air quality. It allows the public transportation systems to significantly reduce diesel emissions by burning O2Diesel™ fuel at no additional cost to the transit systems.

MTA is the fourth public transportation system to join CityHome and represents the largest fleet conversion to date under the CityHome program. With an annual consumption close to one million gallons, the MTA plans to convert all 140 of its diesel-powered coaches and para-transit vehicles to O2Diesel's cleaner burning ethanol-diesel fuel in early August 2005.

Launched nationally on March 10 in Lincoln, NE, CityHome is an innovative partnership involving public transportation systems, O2Diesel and corporate sponsors. The sponsors make it possible for participating cities to offset the added cost of O2Diesel's ethanol-diesel fuel blend.

"Des Moines and the entire state of Iowa are virtually synonymous with ethanol production, and we are pleased to have MTA's commitment to convert its buses to O2Diesel's ethanol-diesel fuel," said Alan Rae, CEO of O2Diesel. "CityHome continues to prove itself as a valuable air quality and community relations program that benefits local residents. Additionally it allows municipalities to implement an alternative fuel program that begins to loosen the ties to traditional fuel sources by using locally produced renewable ethanol."

"The timing could not be better for the City of Des Moines and the MTA to embrace ethanol-diesel fuel blends for our bus fleet through the CityHome program," said Steve Spade, MTA General Manager. "Not only does CityHome help improve the quality of life for our citizens by reducing diesel fuel emissions, it also has a broader impact across the region by supporting Iowa's agricultural economy, while reducing dependence on foreign oil supplies."

The official press conference to launch the MTA CityHome Program and announce the sponsors will be held in August. Select MTA buses will also display CityHome bus wraps as part of the program.
