Clean Energy noted that an iPhone app station locator will be available by the end of the year to complement its web-based locator at http://www.cnglngstations.com.The LNG fueling stations coincide with the arrival of new natural gas truck engines well suited for heavy-duty, over-the-road trucking. At the ATA Summit, executives from engine manufacturers and original equipment truck manufacturers such as Cummins-Westport, Kenworth, Peterbilt, Navistar, Freightliner and Volvo presented their plans to rollout a variety of Class-8 trucks and engine sizes allowing for varied road and driving requirements. Jim Arthurs, President of Cummins Westport Inc., reiterated the scheduled launch of the much-anticipated ISX 12 G natural gas engine to begin in Spring 2013 with full production and delivery by Fall 2013. Presenting at the Natural Gas Summit were executives from all segments of the trucking industry including the CEOs of the three largest truck stop chains, natural gas producers ConocoPhillips and Exxon and representatives from some of the largest shippers and truckers who are already benefiting from transitioning a portion of their fleets to natural gas. Governor Bill Graves, President and CEO of the ATA, called the trucking industry’s transition to natural gas “historic” and compared it to two other major milestones in the industry – deregulation and the formation of the ATA. ATA Chairman Michael Card, who is also president of Combined Transport Inc., said, “We are truly at the cusp of a potential revolutionary change in the trucking industry” as it moves toward more use of natural gas as a transport fuel. Clean Energy’s ANGH stations are in addition to the ongoing CNG station building planned for the company's traditional markets in transit, refuse, airport/taxi/shuttle and local/regional trucking, which activity accounts for 60 station projects in 2012 and is expected to account for approximately the same number in 2013.
