The prototype vehicle, a 425 hp Volvo VNL retrofitted with a US version of Clean Air Power’s patented Dual-Fuel Genesis-EDGE product, successfully made the 2,720 mile journey across the US from the group’s manufacturing facility in Poway, California to the Convention Center in Washington DC.

The truck, which runs primarily on liquid natural gas (LNG), started with a full tank of LNG in San Diego and refueled at a LNG filling station in Dallas during what was the first coast-to-coast crossing of the US by a LNG/Dual-Fuel vehicle, according to the company. 1,000 miles were covered in Dual-Fuel operation with the balance in diesel.

The company anticipates that the first customer trial vehicles will be on the road and undergoing validation by the end of 2013, with production commencing in early 2014.
