The lower cost of fuel for natural gas-powered highway tractors compared to their diesel-fired brethren could make it more profitable for trucking companies to engage in longer lengths of haul for intermodal shipments.
Farmers, waste management companies and the energy industries have long experimented with converting methane, a byproduct of decomposing organic matter, into transportation fuel.
Those efforts have met with mixed success, and a renewable natural gas fuel has not been widely available in the United States. But now, one leading supplier of natural gas transport fuel is taking a big step toward changing that.
Beginning in July 2013, Procter & Gamble will work with eight transportation carriers to convert up to 20 percent of its North America truck load shipments to natural gas vehicles within two years. By meeting this goal, it is expected P&G will incur savings for the converted lanes and reduce greenhouse gas emissions (GHG) by nearly 5,000 metric tons (or the equivalent GHG emissions from 1,000 passenger vehicles for a year).
