Clean Energy Fuels Corp. RNG Engine Trial:
J.B. Hunt Transport Services is trialing Clean Energy Fuels Corp.’s new Cummins X15N engine, a 15-liter renewable natural gas (RNG) engine, on a 2025 Peterbilt 579 day cab tractor.
The trial lets fleets test the engine over regular routes for up to two weeks.
Widespread Fuel Availability:
Clean Energy Fuels Corp. supports the testing program with over 600 stations across North America, providing RNG for the trials.
J.B. Hunt’s Commitment to Sustainability:
The program aligns with J.B. Hunt’s sustainability goals of reducing carbon emissions across the supply chain and piloting new clean fuel technologies.
RNG’s Environmental Impact:
Renewable natural gas, derived from organic waste, can reduce truck emissions by up to 300% compared to diesel, as per the California Air Resources Board.
It achieves a negative carbon intensity score (-40), meaning it removes more carbon from the atmosphere than it emits.
RNG Sources:
RNG is produced from methane captured at sources like dairy farms, reducing greenhouse gas emissions with minimal environmental impact.
J.B. Hunt’s Experience with RNG:
J.B. Hunt has over 15 years of experience exploring RNG-powered vehicles, with over 180 RNG trucks currently in service.
Sustainability Goals:
J.B. Hunt aims to reduce carbon emissions intensity by 32% by 2034 (from a 2019 baseline).
The company achieved 50% of its goal by 2023 through initiatives like shifting road shipments to rail.
Future of Trucking Industry with RNG:
The demo program will help J.B. Hunt assess RNG’s operational efficiency and decarbonization potential.
RNG-powered engines could lead the trucking industry towards sustainable growth without compromising performance.
Impact on the Industry:
If successful, the program may set the standard for low-carbon, sustainable fuel solutions in the heavy-duty trucking industry.
