NEWPORT BEACH, Calif. – Clean Energy Fuels Corp. (Nasdaq: CLNE) announced today that it will begin supplying its Redeem renewable natural gas (RNG) to 118 Catalina Pacific®, a CalPortland® Company, ready-mix concrete trucks which operate throughout Southern California. By converting these trucks to Redeem, Catalina Pacific® will operate the cleanest ready-mix concrete fleet in the United States, reducing greenhouse gas emissions (GHGs) by over 70 percent and smog-causing NOx emissions by over 90 percent (compared to a 2010 diesel engine).

By adopting a combination of Clean Energy’s Redeem™ RNG with the new Cummins Westport natural gas engine Catalina Pacific is able to achieve zero emissions from its fleet vehicles, while saving millions of dollars a year in fuel costs.

“Switching to zero emission engines fueled by renewable natural gas instead of diesel has been a real game changer,” said Allen Hamblen, president/CEO of CalPortland. “We look forward to continued exploration of clean alternatives that will make a positive impact on the environment and demonstrate our ongoing commitment to the community.”

An industry leader on energy conservation and environmental quality for more than a decade, CalPortland’s Energy Management Services Program is dedicated to monitoring and improving the functionality of energy use across its operations, which include 65 ready mix plants, 25 aggregate quarries, and 16 cement plants/terminals. The company has been awarded the prestigious U.S. Environmental Protection Agency’s Energy Star® Partner of the Year for 14 consecutive years.

Catalina Pacific’s 118 concrete mixers are expected to consume an average of 75,000 gallons of Redeem fuel per month, which displaces approximately 8,365 metric tons annually of GHG emissions. The trucks will fuel at two Catalina Pacific private time fill stations, as well as Clean Energy’s network of public access stations in Southern California.

“CalPortland has been a trailblazer in sustainable initiatives, and to date has made the largest investment in natural gas vehicles within the concrete industry in the western United States,” said Chad Lindholm, vice president of sales, Clean Energy. “By converting its fleet to the new clean natural gas engine technology and Redeem, CalPortland will dramatically reduce the amount of smog and greenhouse gases it produces. We congratulate them on their leadership.”
