Supply Chain Fleet Operators Increasingly Turn to Natural Gas Power

Fleet Trucks Fuel at Clean Energy’s National Network of CNG & LNG Stations —
Seal Beach, CA (March 26, 2012) — In increasing numbers, major U.S. contract freight carriers are deploying heavy-duty natural gas-powered trucks to support their customers’ supply chain transport requirements. Clean Energy Fuels Corp. (Nasdaq: CLNE), North America’s leading supplier of natural gas fuel for transportation, contracts with carrier fleet operators to provide compressed natural gas (CNG) or liquefied natural gas (LNG) fueling services at Clean Energy public access stations nationwide.

Among the most recent for-hire fleet operators to opt for natural gas fuel are Premier Transportation, headquartered in Atlanta, Georgia; Transplace, Frisco, Texas and Glacier Transportation & Logistics, Atlanta, Georgia; Dillon Transportation LLC, Burr Ridge, Illinois; C.R. England, Salt Lake City, Utah; Ryder Dedicated Logistics, El Segundo, California; CEVA Logistics, Hoofddorp, the Netherlands; and Werner Enterprises, Omaha, Nebraska.

James Harger, Chief Marketing Officer, Clean Energy, said, “Like Premier, Transplace, Glacier, Dillon, C.R. England, Ryder, CEVA and Werner, truck fleet operators across the country are turning to natural gas power. They seek fuel cost savings, reduced foreign oil dependence, and the environmental benefits of this abundant American resource. Clean Energy commends these companies, and many others like them, for their visionary leadership in the retail and customer products transportation sector.”

Premier Transportation
Premier Transportation is a nationwide provider of transportation and logistics solutions to the retail department stores and consumer products industries. Premier’s CNG trucks will initially be deployed in major metropolitan areas throughout the U.S. Premier will fuel exclusively at Clean Energy facilities and it is expected that each truck will consume over 15,000 gallons per year.

Transplace and Glacier Transportation & Logistics
Third party logistics leader Transplace and Sunny Delight Beverages Co. have partnered with Glacier Transportation and Clean Energy to deploy a new CNG-powered truck fleet. The five-year agreement will transport products such as Sunny Delight and Fruit2O beverages to customers across the Southern California market. Glacier expects the transition from diesel power to CNG fuel for its fleet operations will result in substantially less greenhouse gas emissions and reduced fuel costs.

Transplace has been Sunny Delight’s 3PL (third-party logistics) provider since 2006. Transplace Director of Operations, Clint Dearing, said, “Both Clean Energy and Glacier Transportation have proven to be outstanding partners as we worked together through implementing the CNG fleet with Sunny Delight. Transplace used our expertise to give Sunny Delight value added services through contract negotiations, transportation management, and carrier coordination.”

Dillon Transportation LLC
Dillon’s temperature-sensitive tanker truck fleets operate throughout the U.S. and Canada, with contract services concentrated east of the Rocky Mountains. Dillon LNG-powered trucks now deliver raw materials to Owens Corning industrial production plants in Texas and Ohio. Owens Corning is a leading global producer of residential and commercial building materials, fiberglass reinforcements and engineered materials for composite systems. Dillon’s operations are averaging nearly 250,000 miles per truck per year — consuming over 40,000 gallons per truck in both Ohio and Texas. Dillon is now evaluating LNG trucks for its operations in Florida and Georgia. Dillon fuels its fleet exclusively in Clean Energy’s American Natural Gas Highway™ LNG station network.

C.R. England
One of America’s largest contract freight carriers, C.R. England, has deployed a new fleet of Peterbilt LNG trucks to transport products out of Southern California to the Las Vegas area. The trucks feature 15-liter Cummins-Westport LNG engine systems and fuel in Clean Energy’s Southwest Corridor of LNG fueling stations. C.R. England operates a fleet of 4,000 trucks and consumes over 70 million gallons of fuel per year.

Ryder Dedicated Logistics
Ryder provides product transportation services for Fresh & Easy, a growing Western U.S. chain of retail grocery stores. Fresh & Easy is a subsidiary of Tesco, which is among the world’s leading retailers. Ryder operates a regional fleet of CNG tractors for Fresh & Easy’s Moreno Valley distribution center. The fleet is expected to consume more than 400,000 gallons of CNG fuel annually.

CEVA Logistics
A global logistics company involved in freight management, contract logistics, distribution, and transportation management, CEVA uses its new fleet of LNG trucks to transport American Honda parts from the Honda distribution center in Ontario, Calif. to dealerships and independent companies throughout Greater Los Angeles.

The combined fleet consumes well over 100 million gallons annually.

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 lowers greenhouse gas emissions up to 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.
