Accelerating its development program to support growing natural gas vehicle fueling demand, Clean Energy Fuels Corp. (Nasdaq:CLNE), North America’s leading provider of natural gas fuel for transportation, significantly increased its fueling station project completions during 2011. During 2011, Clean Energy completed 68 fueling station projects in 16 states, including five LNG truck fueling stations on America’s Natural Gas Highway. “We increased the number of station projects completed during the year by 50% over 2010,” said Andrew J. Littlefair, President and CEO of Clean Energy. “These included stations serving transit (7), refuse (18) and airport/taxi/shuttle (28) operations around the country, as well as locations situated to support the needs of local and regional trucking and small fleets (15).” “During the second half of 2011, Clean Energy received total investment commitments of $450 million, largely to fund substantially more fueling station development going forward, particularly LNG truck fueling stations along America’s Natural Gas Highway,” noted Littlefair. “We are pleased to be leading the way for key segments of our nation’s transportation system to convert to the use of natural gas fuel, saving money and helping the environment and our nation’s energy security through growing independence from imported oil,” Littlefair added. 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. Additionally, natural gas is a secure North American energy source with 98% of the natural gas consumed produced in the U.S. and Canada. Clean Energy (Nasdaq: CLNE) is the largest provider of natural gas fuel for transportation in North America and a global leader in the expanding natural gas vehicle market. It has operations in CNG and LNG vehicle fueling, construction and operation of CNG and LNG fueling stations, biomethane production, vehicle conversion and compressor technology. Clean Energy fuels over 25,000 vehicles at 273 strategic locations across the United States and Canada with a broad customer base in the refuse, transit, trucking, shuttle, taxi, airport and municipal fleet markets. We are building “America’s Natural Gas Highway,” a network comprised initially of approximately 150 LNG truck fueling stations connecting major freight trucking corridors across the country. Clean Energy del Peru, a joint venture, fuels vehicles and provides CNG to commercial customers in Peru. We own (70%) and operate a landfill gas facility in Dallas, Texas, that produces renewable natural gas, or biomethane, for delivery in the nation’s gas pipeline network, and we plan to build a second facility in Michigan. We own and operate LNG production plants in Willis, Texas and Boron, Calif. with combined capacity of 260,000 LNG gallons per day and that are designed to expand to 340,000 LNG gallons per day as demand increases. NorthStar, a wholly owned subsidiary, is the recognized leader in LNG/LCNG (liquefied to compressed natural gas) fueling system technologies and station construction and operations. BAF Technologies, Inc., a wholly owned subsidiary, is a leading provider of natural gas vehicle systems and conversions for taxis, vans, pick-up trucks and shuttle buses.
