Truckin' - Can the Trucking Sector's Shift to CNG and LNG Survive Low Diesel Prices?
U.S. trucking companies, trash haulers and transit agencies continue to invest in new vehicles fueled by compressed natural gas or liquefied natural gas, in part to meet corporate or agency carbon-footprint goals. But the economic rationale for switching trucks and buses from diesel to CNG or LNG is weaker than it was a few years ago, when diesel cost two-thirds more than natural gas fuels on a per-BTU basis — prices for diesel, CNG and LNG are now in the same ballpark. Also, developing regional or national networks of CNG/LNG fueling stations doesn’t come cheap. Today, we discuss the growing use of natural gas in trucks and buses — and threats to that trend.
