Clean Energy Contracts to Add Four New CNG Fueling Stations at Airports in Four States

New CNG Fueling Facilities Are Slated for Tampa, New York City, New Orleans
and Philadelphia Airports —

Seal Beach, Calif. (May 5, 2011) — Clean Energy Fuels Corp. (Nasdaq: CLNE) has signed long-term agreements with four major airport complexes in four states to design, build, own and operate new compressed natural gas (“CNG”) stations to support ground transport vehicles and off-airport parking shuttles. The new Clean Energy stations, available 24/7 for public access, will be located in Tampa, Florida; New York City, New York; New Orleans, Louisiana; and Philadelphia, Pennsylvania.

“With these new agreements, the number of major airports that Clean Energy supports with CNG fueling services will increase from the current 23 to 27. Airports and allied ground transport services have become magnets for natural gas vehicle usage of all types in response to the need to curtail emissions, decrease fuel costs, and reduce dependence on imported oil,” said James Harger, Chief Marketing Officer, Clean Energy. “We welcome this opportunity to support forward-looking airport fleet operators and off-airport parking leaders as they transition their fleets to natural gas power.”

Currently priced significantly less than diesel, natural gas fuel produces up to 30% lower greenhouse gas emissions in light-duty vehicles and 23% percent lower emissions in medium to heavy-duty vehicle applications. U.S. Department of Energy reports estimate that 98% of the natural gas consumed in the U.S. is sourced in the U.S. and Canada.

Tampa, Florida International Airport
At Florida’s Tampa International Airport, the Clean Energy public access facility will support the airport’s expanding fleet of low carbon, low emission CNG passenger and employee transit buses, as well as off-airport hotel and parking shuttle fleets. Tampa International will be the first airport in Florida to implement CNG power for its ground transportation vehicle fleets.

John F. Kennedy International Airport, New York City
Clean Energy has contracted with JFK AP, LLC to develop, own and operate a new CNG fueling station at the Airport Plaza convenience store and fueling center adjacent to JFK International Airport. The station, located on land owned by the Port Authority of New York and New Jersey, will be available 24/7 for public access. It will support JFK’s expanding on-airport CNG-powered ground transport vehicle fleets, off-site Parking Spot CNG shuttle buses, taxis and other CNG vehicles operating in the area.

Louis Armstrong New Orleans International Airport, Louisiana
Clean Energy has contracted for a new CNG fueling station adjacent to Louisiana’s New Orleans International Airport on property leased by off-airport shuttle operator Park N’ Fly. The station will provide CNG fueling services to Airport Authority-operated shuttle vehicles, CNG-powered taxis, and varied off-airport parking shuttle fleets, including the Park N’ Fly fleet.

Philadelphia, Pennsylvania International Airport
The new Clean Energy Philadelphia Airport CNG fueling station will be located on property owned by Wallypark, a national off-airport parking shuttle operator. The station will be available 24/7 for public access and will provide CNG fueling services to Airport Authority-operated shuttle vehicles, CNG-powered taxis, and varied off-airport parking shuttle fleets, including the Wallypark CNG shuttle fleet.
