Clean Energy Fuels continues to grow its natural-gas fueling network, with expansions in Texas, Pennsylvania and New York, and more fleets signing on to fuel at the nationwide network.

It has begun fueling at its Amarillo, Texas, and Oklahoma City facilities to serve UPS' growing heavy-duty liquefied natural gas truck fleet.

UPS has deployed six heavy-duty LNG trucks that are fueling at Clean Energy's newly-opened Oklahoma City station. An additional four trucks are expected to begin fueling at this station within weeks. The Texas station is fueling 10 LNG trucks under its previously announced bulk fueling agreement with UPS.

Additional truck fueling agreements were also announced for fleets fueling across Clean Energy's nationwide network from Los Angeles, Calif., to Jacksonville, Fla. Among the most notable:

• The carrier E.J. Madison has deployed a fleet of 20 long haul dual-fuel LNG trucks on routes spanning the Clean Energy Fuels network in Los Angeles; Phoenix; Houston, Dallas and San Antonio in Texas, and Jacksonville, Fla. The fleet currently has traveled over 500,000 miles and intends to expand with an additional 30 dual-fuel LNG/diesel trucks in the coming months, according to Clean Energy.

• Dillon Transport has deployed eight additional heavy-duty compressed natural gas trucks, which will fuel at Clean Energy's Fair Oaks Dairy station in Indiana.

Meantime, in Pennsylvania, the Department of Community & Economic Development has awarded Clean Energy approximately $2.5 million to offset the cost of constructing two natural gas stations to fuel light, medium, and heavy-duty vehicles with CNG or LNG.

The stations will be located in Pittston Township, Pa., and Pottsville Township, Pa., to serve the heavily trafficked I-81 and I-476 highways. Both stations are projected to open by the end of 2014.

Additionally, 10 Clean Energy customers were among the 25 companies awarded approximately $7.7 million in funds by the state of Pennsylvania for 129 heavy-duty natural gas vehicle conversions.

Finally, in New York, fueling has also begun at Clean Energy Fuels newest public access CNG station, located at JFK International Airport within the newly opened JFK multi-fuel travel plaza, the only travel plaza in New York City available to motorists.

Clean Energy will be fueling many types of fleets including refuse trucks, heavy and medium duty trucks, ready-mix concrete trucks, as well as shuttles and taxis that directly serve JFK travelers.
