  • State trucking association officials say interest in NGVs rising, increased fleet own

    Interest in trucks fueled by natural gas is increasing among truckingfleets, according to a recent NGV Today survey of officials at statetrucking associations. But barriers to deploying NGVs remain, andthe trucking association officials pointed to efforts to raise awarenessof the NGV marketplace as well as government policy initiatives thatthey think would encourage more trucking fleets to deploy NGVs.As the chart shows, 85 percent of the trucking association officialssurveyed responded that interest in NGVs is increasing among,,,Read more

    Crude oil originally produced mostly kerosene and the natural gas and gasoline were burned off. Then the gasoline engine came along. A pair of chemical engineers at Standard Oil of Indiana had an idea to add pressure to the standard heating process used in distillation. Under both heat and pressure, it turned out that heavier molecules of kerosene, with up to 16 carbon atoms per molecule, "cracked" into lighter molecules such as those of gasoline, with 4 to 12 carbons per molecule, Thermal cracking, as the process came to be called, doubled the efficiency of refining, yielding 40 percent gasoline. Burton was issued a patent for the process in 1913.

    Direct-injection turbo-charged diesel engines that have now become standard emerged during the 1950s, in large part thanks to the work of Volvo in Sweden. Engine manufacturers such as the U.S. Cummins and British Perkins companies began heavily supplying the market with diesel engines through the 1960s as the trucking industry began its conversion from standard gasoline to diesel.

    Today, CNG comprises 3 per cent of the transportation sector compared to 22 per cent diesel and 56 per cent gasoline.

      Erik Neandross for ACT News - Fleet Owner August 22, 2018: The Truth about NatGas Tractors

      In spite of the headlines, or lack thereof, the heavy-duty natural gas truck market continues to steadily march forward and mature, and is on track to have one of its best sales years ever. Class 8 truck orders – regardless of technology/fuel type – for July 2018 was the highest number of truck orders recorded since March of 2006, and several of the months before July were record breaking months as well.

      A major driver of this growth is the booming U.S. economy. And economic activity translates to growth in the manufacturing sector, which in turn translates to growth in the trucking industry to move the goods that Americans buy. Truck orders have also likely gained an additional boost due to the new tax law, which for 2018 offers companies the ability to accelerate depreciation on capital assets.

      Regardless of the fact that natural gas engines, CNG/LNG fuel systems, and other necessary components are readily available from reputable suppliers across the country, the OEM build slots – or lack thereof – is hindering the immediate growth of heavy-duty NGVs here in 2018. NGVs are currently one of the only commercially available vehicle platforms that can provide significant emission reductions across most heavy-duty weight classes.

      NGVs are currently one of the only commercially available vehicle platforms that can provide significant emission reductions across most heavy-duty weight classes. This is particularly true now that there is a 12-litre natural gas engine from Cummins Westport that is their newest addition to their line of “near-zero emission” products that are certified to emit 90% less emissions than the most stringent national emissions standard.

        Roselynne Reyes for Green Fleet May 23, 2018 - What’s the Future for CNG?

        In recent years, CNG has not made headlines the way it used to. Gasoline and diesel prices remained low for a few years and electric vehicle technology has advanced. It has become harder to justify the costly up-front investment in CNG vehicles and fueling infrastructure — which is also a problem for those basing their return-on-investment calculations on higher fuel costs.

        Government Fleet spoke to a few fleets that have made the investment to see how this shift away from CNG has affected their plans:

        The City of Phoenix purchased its first CNG solid waste trucks and, since 2012, the fleet has replaced its diesel solid waste trucks with CNG-powered models. CNG now powers 100 of the fleet s 225 heavy-duty solid waste trucks. Overall CNG vehicles are not more costly to maintain, there s good public relations with them, and we have the infrastructure, Gregg Duckett, Public Works operations manager for the City of Phoenix, said.

        The City and County of Denver has used CNG in its solid waste vehicles for about six years. CNG vehicles act like unleaded gasoline vehicles because there s no urea and no regens, said Todd Richardson, fleet management director. This makes it ideal in an urban environment. Anywhere you can have a fixed route and it’s a predictable fixed route where you can come home every night and refuel the units on a slow-fill, it absolutely makes sense to use CNG.

        City of Columbus Ohio continues to replace diesel trucks with CNG, and plans to reach 404 CNG vehicles by 2020 because it is the right thing to do and it saves the city money, Kelly Reagan, fleet administrator, said. You do need to take a long view, because fuel tomorrow can be $1.90 a gallon and the next day it could be $4 a gallon.

        The City of Tulsa is diversifying its alternative fuel options by exploring technologies such as electrification and renewable diesel. Richardson noted there is a potential for growth for CNG as more fueling stations become available. But he doesn’t see much of a future for CNG in the long run. He believes that electric will be the next big powertrain and, until then, diesel and unleaded gasoline will continue to rule.

        Duckett is a little more wary about the future alternative fuel for heavy-duty fleets. Whether that’s electric, or hydrogen, or some other source, he does not believe that technology will be ready any time soon. For now, he is sticking to CNG and B-20.
