   J.B. Hunt has 200 compressed natural gas trucks, most of which have 12-liter engines. Over the past 12 months, the carrier introduced 15-liter RNG engines to its fleet. Full production of Cummins’ X15N natural gas engine got underway in September 2024. […] J.B. Hunt Transport Services — which ranks No. 3 on the Transport Topics Top 100 list of the largest for-hire carriers in North America, No. 1 on the intermodal sector list and No. 2 in the truckload/dedicated segment — has more than 22,000 trucks overall. J.B. Hunt trucks are fueled 8,000 times a day. The carrier buys the equivalent of 200 million gallons a year of diesel. But biodiesel, renewable diesel and RNG now account for 22% of J.B. Hunt’s total fuel by volume, said Mounce. “We’re going to convert hundreds more of these trucks” to RNG, Mounce said at American Trucking Associations’ Management Conference & Exhibition. “We’re in a spot now where we’re a lot closer to cost parity.”
