Clean Energy Fuels Corp. has partnered with Quarles Petroleum, a Mid-Atlantic fleet fuel station operator, to add natural gas fueling services at selected Quarles station locations.

Quarles operates approximately 125 fueling stations that are available 24/7 to serve its commercial vehicle fleet customers in strategic urban areas of Virginia, Maryland, Delaware, Pennsylvania, West Virginia, and North Carolina. Quarles' customers have exclusive access to the stations by using company-issued charge cards for fuel purchases. Initially, Clean Energy expects to add natural gas fueling capability at several existing Quarles stations in the Richmond, Virginia and the Washington Dulles International Airport areas.

"Many of our customers are interested in natural gas-powered vehicles for their fleets," explained Ben Wafle, President, Quarles Petroleum.

Currently priced up to $1.50 or more per gallon lower than diesel or gasoline (depending upon local markets), the use of natural gas fuel reduces costs significantly for vehicle and fleet owners, and reduces greenhouse gas emissions up to 30% in light-duty vehicles and 23% in medium to heavy-duty vehicles, according to advocates.
