The recent low prices and abundance of natural gas have the trucking industry making steps toward implementation of natural gas trucks and fueling stations. Heavy trucks account for more than one-tenth of the oil consumption in the United States and natural gas provides an opportunity for reducing fuel costs and emissions in the industry. 
“The route is known, the mileage is high and economics is the primary decision factor [for liquefied natural gas in heavy trucking],” said Tiffany Groode, director of the HIS Automotive Long-Term Planning and Scenarios Service.  The long distances, regular routes, and high volume capacity of trucks makes supplying for liquid natural gas trucking economical. Liquefied natural gas is about 30% more cost efficient than diesel with current U.S. prices.
While the opportunity seems promising, it proposes a chicken or the egg problem. What will come first: natural gas trucks or natural gas filling stations? The infrastructure does not currently exist for natural gas trucking to be feasible. In order for filling stations to have a purpose, there must be a market for them to serve (i.e. Natural gas trucks need to be somewhat common on the road). For natural gas trucks to be a practical substitute for diesel trucks, they need to be able to travel the same distances and refuel regularly.
So what comes first? In November 2012, T. Boone Pickens, a major oil and gas investor, invested in a network of 70 natural gas fueling stations.  The natural-gas filling stations would be implemented at existing truck stops on major highways spaced about 250 miles apart with a goal of increasing to 150 stations in 2013. There are currently 70 natural gas fueling stations in 33 states. However, most are dormant and awaiting the introduction of the first generation of natural gas trucks.LNG trucks are about an $80,000 premium compared to traditional diesel trucks but would make up for the cost within 3 years without government incentives. Cummins Westport will begin production this month on an 11.9-liter natural gas engine. Other truck manufacturers such as Freightliner, Kenworth, Peterbilt, Volvo, and Navistar are planning to use new LNG rigs on the road by August.
The low prices of natural gas are alluring however; the switch to LNG rigs would also decrease the emissions of greenhouse gases. Natural gas has decreased carbon dioxide emissions by 30 percent but, there is a significant increase in the leakage of methane. Despite this leakage, a switch from diesel to natural gas would decrease total greenhouse gas emissions from 6 to 11 percent.
There are also added benefits to the truck drivers such as a lack of smell and quieter ride. They are required to wear insulated gloves and face shields as they refuel due to the extremely chilled fuel. However, these have not been seen as drawbacks.
Despite the growth of infrastructure, the worry still is that there will not be enough fueling stations in to get from point to point.
