In the August issue of HDT, we kicked off a series on "Natural Gas: What Fleets Need to Know." In addition to the features in the magazine, on this page we offer additional online articles and resources.

We'll be adding to this page as we go along, so bookmark it and visit us again.

The HDT Print Series

Natural Gas: What Fleets Need to Know, Part 1
In 2011, the use of natural gas as a vehicle fuel rose 7.1% year over year and 38% from 2006, federal data show. It more than doubled during the past decade, to 38.85 million cubic feet in 2011.

Natural Gas: What Fleets Need to Know, Part 2: New Engines, More Options
A limited number of engine options has meant it's just not a viable strategy for some fleets, especially the type of regional linehaul fleets that may be best poised to take advantage of the limited but growing fueling infrastructure. That's set to change significantly in the next two years.

Natural Gas, What Fleets Need to Know Part 3: What's the Payback?
The environmental and image benefits of being "green" and reducing dependence on foreign oil are among the reasons fleets are looking at natural gas fuel for trucks, but even the most diehard "green" fleet is still looking for a return on its investment.

Six Questions to Ask Yourself about Natural Gas
Interest is high in natural gas as a heavy-duty truck fuel. With a dollar per diesel-equivalent gallon differential, why wouldn't it be? Natural gas is likely to remain less expensive than diesel for the foreseeable future, and domestic supplies of the stuff are plentiful. Is natural gas a savior-in-waiting for beleaguered diesel buyers? Maybe, but here are six questions you need to ask before taking the plunge.<!break>

Carriers Looking at Natural Gas, See Fuel Availability, Equipment Cost as Hurdles
More than half of large carriers say they are considering buying natural gas fueled trucks, but there are hurdles, according to a study from Transport Capital Partners and ACT Research.

Study: Annual Sales of Natural Gas Trucks and Buses Will Surpass 180,000 by 2019
A new report from Pike Research forecasts steady growth in the market for natural gas trucks and buses.


Natural Gas Truck and Engine Information
Announcements about new natural gas engines, bi-fuel engines and aftermarket conversion systems are coming faster and faster.


Natural Gas Fueling Infrastructure Growing
One of the key roadblocks to wider adoption of natural gas fuel by the trucking industry has been a lack of fueling infrastructure. In the past, natural gas was mostly an option only for companies that could return to a central fueling station each night. That's changing, as you'll see in this sampling of recent announcements.
