Dillon Transport uses natural gas as a strategy to go after new customers for whom sustainability is a key requirement.

At a time when many shippers have chief sustainability officers and government contracts are requiring low-emissions or alternative-fuel equipment, some fleets are finding it pays to have natural gas trucks in their arsenal.

Such was the case with two very different fleets who spoke to attendees in an educational session at the Green Fleet Conference this fall in Phoenix, Ariz.: Chicago-based Dillon Transport and Phoenix-based Waste Management.

Dillon Transport

Dillon Transport is a big advocate for natural gas. But in an anecdote illustrating the chicken-and-egg problem of infrastructure, Vice President Charles Musgrove noted that when it took a truck to Capitol Hill to promote incentives for natural gas, it couldn’t get there on its own power. It was shipped by flatbed. However, with the determination of fleets like Dillon, that’s changing.

Dillon started investigating in natural gas four to five years ago. Today it runs both liquefied natural gas and compressed natural gas, depending on the particular location. By the second quarter of 2014 it plans to have 25% of its 500-truck fleet running on natural gas.

In addition to being unusual in using both fuels, Dillon is unusual in its approach to the ROI of natural gas. Instead of focusing on the per-gallon fuel savings, it finds the big appeal of natural gas is its ability to bring in new, sustainability-focused clients. Contracts with those clients are multi-year deals that make the move feasible for Dillon and also lock in prices and capacity for the client.

Musgrove offered a list of common excuses not to use natural gas, and his responses.
• Tractors are too heavy. In fact, he says, they can be lighter with the elimination of the diesel particulate filter, DEF tanks and other emissions equipment.
• Not enough range. Fleets and truck makers are developing more multiple-tank options that extend range. One of the trucks being used in its Tampa operation has two saddle tanks and back-of-cab tanks, giving it a 450- to 500-mile range. The operation is only doing 320 miles per shift.
• The engines aren’t powerful enough. “We have 24 trucks that do it every day” with the 9-liter engines, Musgrove said, and the 12-liter is now available, with 15-liters from two companies in the works.
• I can’t get the ROI without government assistance. Musgrove maintains it’s working for Dillon without funding help.
• Drivers don’t like them. Dillon’s drivers do, he said. They’re quieter, for one thing – and one driver even told him it might have saved his marriage because he no longer came home stinking of diesel fumes.
• Maintenance costs are too high. Dillon has found the costs to be reasonable. With most problems, when they do occur, being covered by warranty. Without maintenance costs to emissions control systems, it may even be cheaper in comparison.
• The infrastructure isn’t there. Not yet, but it’s moving quickly, and there are portable/temporary fueling options available.

Waste Management

California emissions standards may have herded Waste Management into natural gas at first, but it quickly took the reins. Today the Phoenix-based fleet is working to transition its entire 32,000-vehicle fleet.

Marty Tufte, corporate fleet director, said the early driver of the refuse giant’s strategy back in the late ‘90s was really emissions.

The company found that the fuel offered it much more than emissions compliance. It has realized fuel cost savings, maintenance savings and customers demand it.

By the end of 2014, the fleet expects to be approaching the 4,000-vehicle mark in its transition. Although it still has close to 500 LNG trucks in its fleet, all WM’s new investment is CNG.

To support its efforts, the company has more than 50 natural gas stations across the country. It also sells its own brand of Clean N Green CNG in partnership with PetroCard.

WM also has a facility at its Altamont landfill near Livermore, Calif., that converts landfill gas into natural gas to fuel its trucks.

Tufte, who says he “walks the talk” and drives a natural-gas-fueled Honda Civic, says the company got into it in a big way starting in 2009 when it was asked to bid for the business of the City of Seattle. The bid called for either EPA 2007 diesels running 30% biodiesel or alternative fuels.

“At that point I chose alternative fuel, and I don’t regret that decision at all,” he says. “When we looked at that decision later, we went to the corporate office and showed them what the decision had yielded in terms of ROI, and they committed to convert the whole fleet.”

    We now have 5 LNG trucks @ Vons Grocery co. in Southern California, that we have on lease from Tec Volvo. They are 12 liter Cummings engines.
    They are quiet, smooth, and so far performing very well. With 6 fueling stations in our area we are very happy with the program so far.
    Back 14 years we also had LNG trucks that were dual fuel, they worked fairly well, but the technology was new and had if draw backs.
    Today with Cummings LNG ISX12G they have hit a home run !
