FCA US, the North American automaking unit of Fiat Chrysler Automobiles N.V., will invest $40 million to convert 179 trucks in its private fleet to run on compressed natural gas and build in Detroit the largest private CNG fueling station in North America.

American Natural Gas said it has completed a new compressed natural gas fueling station in Lancaster, New York, to support grocery retailer Tops Friendly Markets’ new fleet of 55 CNG-powered tractors from Ryder Inc.

Agility Fuel Systems has reached a seven-year agreement under which it will be the sole provider of natural-gas fuel systems for Freightliner Trucks.

Despite the recent downturn in the price of oil, the use of natural gas as a transportation fuel could displace more than 1.5 million barrels a day of oil demand by 2030, according to a new report.

GE Capital Canada said it has signed an agreement with Shell Canada Products to facilitate the trucking industry’s adoption of liquefied natural gas in that country.

A switch to cleaner-burning natural gas as a fuel for heavy-duty trucks could increase global warming due to the release of methane at drilling sites and the fact that natural gas-powered engines get fewer miles per gallon than traditional diesel-powered engines, according to a report issued May 19 by the Environmental Defense Fund.

Oil has the lowest share of the U.S. transportation fuel market since the 1950s, when steam trains remained a common sight on American railroads.

UPS Freight has added 64 liquefied natural gas-fueled tractors to its fleet. The tractors join UPS’ worldwide fleet of more than 2,500 natural gas-powered vehicles, the company said April 30.

Trucking and natural-gas industry witnesses told a Senate panel Dec. 3 that Congress could spur the use of the alternative fuel in the transportation sector by changing the tax code, subsidizing a fueling network and addressing existing weight restrictions on highways.
