Port of Long Beach Approves Plan to Replace No Less Than 50 Percent of Aging Diesel Trucks with Alternative-Fueled Models

Clean Energy Renews Commitment to Supply Fuel for Thousands of New 'Green' Liquefied Natural Gas (LNG) Trucks Slated for Port Service

SEAL BEACH, Calif.--(BUSINESS WIRE)--

At a special meeting at Port of Long Beach (POLB) headquarters on Feb. 19, 2008, harbor commissioners voted to approve a plan calling for replacement of at least half of current port drayage diesel trucks with trucks powered by clean alternative fuels -- specifically liquefied natural gas (LNG) or other alternative fuels that perform better than 2007 emission standards. Reacting to the move, Clean Energy Fuels Corp. (Nasdaq: CLNE) has renewed its stated commitment to supply clean-burning LNG fuel for thousands of LNG-powered trucks slated to replace aging diesel models as part of the San Pedro Bay Ports' Clean Air Action Plan (CAAP).

The CAAP Clean Truck Program targets the replacement of 16,800 old diesel trucks. The POLB plan calls for the replacement of its trucks with no less than 50 percent new alternative-fueled trucks, as well as new or converted diesel trucks that meet the minimum 2007 emission specifications for reduced harmful particulate matter and nitrogen oxide emissions. LNG trucks provide better emissions performance than the U.S. Environmental Protection Agency's 2007 truck standards, and can achieve the agency's 2010 emission standards while providing a 20 percent greenhouse gas reduction over diesel. The Clean Truck Program aims to cut truck-related air pollution by 80 percent within four years.

"We applaud the Long Beach Board of Harbor Commissioners for their action, a powerful demonstration of their intent to address and mitigate the greenhouse gas and toxic air contaminants that are emitted daily by the thousands of diesel-powered port trucks," said Andrew Littlefair, Clean Energy's President and CEO.

In December 2007, Clean Energy opened the first major LNG truck fueling station adjacent to the port complex that is designed specifically to support CAAP goals. Littlefair explained that the new station is the first of three in the port area that Clean Energy will build in the near future to serve new LNG port drayage trucks.

"Further helping to make the Clean Truck Program's goals a practical reality, Kenworth Trucks and LNG truck engine maker Westport Innovations have stated that they can produce 5,000 new heavy-duty LNG trucks in 24 months," Littlefair added.

Meanwhile, to help meet expanding port and other heavy-duty vehicle requirements, Clean Energy is currently building California's first large-scale LNG production plant in the Mojave Desert, approximately 75 miles northeast of Los Angeles. At the new plant, Clean Energy will liquefy pipeline gas for shipment to customers by tanker trailers. Initial production capacity is anticipated to be 160,000 LNG gallons per day, with a potential for expansion, as needed, up to 240,000 gallons per day.
