How RNG Powertrains Are Gaining Traction in Truck Fleets and What It Means for Freight Transport

Renewable Natural Gas Powertrains Gain Momentum Amongst Truck Fleets

There’s a growing buzz in haulage circles about renewable natural gas (RNG) engines, particularly the advent of larger, heavy-duty powertrains that challenge the status quo of diesel dominance. What once sparked hesitation among fleet managers – mainly due to higher upfront costs and untested performance at scale – is now starting to sound more like a promising opportunity for cost savings and sustainability.

From Scepticism to Optimism

Historically, the haulage industry has trod lightly around alternative fuels. The financial pressures felt by fleet operators, who juggle the costs of new vehicles and evolving safety standards, made RNG-powered lorries somewhat of a tough sell. But the tide appears to be turning.

One of the country’s largest fleet operators, J.B. Hunt Transport Services, has been pioneering this shift. The company operates about 200 compressed natural gas (CNG) lorries equipped primarily with 12-litre engines but recently started incorporating 15-litre RNG engines after the full-scale launch of the Cummins X15N natural gas engine in late 2024.

According to their energy and sustainability leadership, the 15-litre engines offer improved fuel economy, outperforming the 12-litre units by approximately 3% to 5%. This not only highlights performance gains but also points towards achieving closer cost parity with diesel trucks.”

The Power Behind the Numbers

Here's a quick rundown on how fleets like J.B. Hunt are adjusting and what they're seeing in terms of RNG adoption:

OEMs Step Up WiNew RNG Engine Offerings

The emergence of larger RNG engines such as the Cummins X15N powertrain marks a significant milestone. People in the business are particularly excited because this engine can deliver power and torque comparable to traditional diesel plants, reaching up to 500 horsepower and 1,850 pound-feet of torque.

This isn’t your grandad’s natural gas engine. The X15N has a broader torque curve and offers better low-end torque compared to older 12-litre models, which means it’s more versatile and responsive in on-highway applications. That’s music to the ears of freight operators who demand reliability and performance.

Available Truck Models and Market Response

Freightliner has opened new orders for its fifth-generation Cascadia tractors equipped with the X15N engines. This truck, revamped in 2024, remains the top-selling Class 8 tractor in the United States.

Meanwhile, Kenworth and Peterbilt also support X15N engines across popular models such as the T680, T880, 579 semi, 567 vocational, and 520 refuse variants. Production of these lorries is syncing with surging interest in RNG powertrains.

Fuelling Infrastructure and Production Growth

RNG lorries require a robust fuelling network, and progress here is nothing short of impressive. Over the past decade, natural gas fuelling stations have blossomed from scarce outposts to a widespread network that rivals traditional fuelling stations. This growth mitigates one of the biggest hurdles for RNG adoption – convenient refuelling.

Production facilities for RNG are also scaling up. For example, partnerships such as the one between Opal Fuels and waste management authorities have opened new landfill-based RNG production plants, turning waste into valuable fuel. This push enlarges the supply base and enhances the environmental benefits of RNG by repurposing methane emissions from waste.

Natural Gas Vehicle Fuel Consumption Snapshot

• In 2024, U.S. natural gas vehicles consumed fuel equivalent to 774 million gallons of petrol.
• Out of that, 861TWh of vehicles were fuelled by RNG, marking a clear trajectory towards cleaner alternatives.
• The US remains the largest conventional natural gas producer globally, reinforcing the country’s position in the RNG sector.

Broader Implications for Logistics and Freight Transport

The upturn in RNG-powered haulage presents exciting possibilities for the logistics industry. Reduced emissions, better fuel economy, and advancing engine technology collectively facilitate greener supply chains. For companies moving massive fleets or managing large-scale freight contracts, RNG powertrains could translate to lower operational carbon footprints without sacrificing power or mileage.

Moreover, as infrastructure gaps close and fuel availability increases, the dispatch and haulage operations become more flexible. Fleets can rely on RNG without the worry of fuel scarcity, enabling smoother planning and distribution cycles. This is a game-changer when it comes to international shipments and bulky cargo that demand consistent transportation schedules.

Key Benefits Impacting Logistics

• Дотримання екологічних норм: RNG options help fleets meet increasingly stringent emission regulations worldwide.
• Cost Control: Improved fuel economy and price parity reduce total cost of ownership over time.
• Operational Stability: More filling stations popping up makes longer journeys easier and more reliable.
• Fleet Versatility: Engine performance on par with diesel means no compromises on power or hauling capabilities.
