As the world aims for a greener future, the push towards decarbonization is reshaping the landscape of heavy-duty transport. Among various alternatives, compressed natural gas (CNG) is emerging as a practical solution that aligns economic viability with environmental responsibility. With challenges such as fluctuating diesel prices and stringent emissions regulations, many fleets are now considering CNG as a reliable and established technology.
In North America, the rapid increase in diesel costs, coupled with evolving regulatory frameworks, has prompted an industry-wide reevaluation of fuel sources.
Electric and hydrogen technologies may hold promise, but CNG stands out as an immediately deployable option that offers both efficiency and performance. The companies innovating in this sector are poised to reap significant benefits as fleet operators seek cost-effective alternatives.

The advantages of CNG in the trucking industry
The economic and environmental attributes of CNG are increasingly relevant in today’s market. The U.S. Energy Information Administration reports that natural gas prices have remained consistently lower than diesel, often by 50 to 60 percent since 2015, with forecasts suggesting this trend will persist. This price stability provides a strategic advantage for fleet operators looking to manage their expenses more predictably.
CNG as a proven alternative fuel
According to the North American Council for Freight Efficiency, natural gas is recognized as the most proven and scalable low-emission fuel for heavy-duty applications. Trucks utilizing CNG can achieve the necessary range and power while emitting fewer pollutants compared to traditional diesel engines. The average daily distance traveled by these vehicles, ranging from 400 to 600 miles, is well within the operational capabilities of CNG-powered trucks.
Market forecasts suggest that the global CNG heavy-duty truck market could grow from $7.1 billion to nearly $12 billion, reflecting a compound annual growth rate of 5.7 percent. This growth is largely attributed to the conversion of existing fleets to CNG and the integration of new original equipment manufacturers (OEMs) into the market.
Innovation driving CNG adoption
The appeal of CNG lies not only in its cost-effectiveness but also in its compatibility with existing infrastructure and technologies. Unlike battery electric and hydrogen systems, CNG can leverage established fueling networks, making it a more accessible option for fleet operators. The U.S. Department of Energy indicates that CNG engines can reduce greenhouse gas emissions by 15 to 25 percent compared to diesel engines, while also improving air quality through lower nitrogen oxide and particulate emissions.
Technological advancements in CNG systems
Recent innovations have enhanced the performance capabilities of CNG vehicles, making them competitive with diesel engines. For example, the High Pressure Direct Injection (HPDI) system developed by Westport Fuel Systems showcases how CNG can achieve diesel-like performance metrics. This technology allows for exceptional fuel efficiency, robust engine braking, and the ability to cover over 600 miles on a single tank.
Westport’s recent strategic shift emphasizes its commitment to the CNG market. With the divestment of its light-duty business, the company is focusing its resources on expanding its high-pressure control systems and HPDI technologies for heavy-duty and industrial applications. Through its partnership with Volvo Group, Westport has equipped nearly 9,000 trucks globally with HPDI technology, positioning itself at the forefront of CNG advancements.
Investment opportunities in CNG technology
The current landscape presents a unique opportunity for investors. CNG is not only a viable choice today but also a stepping stone towards a sustainable future. Its deployment can lead to significant emissions reductions and cost efficiencies without dependence on maturing technologies like hydrogen or electric vehicles. For investors looking to capitalize on this transition, companies like Westport are well-positioned, given their proven technology and strategic partnerships.
As CNG gains traction in the trucking industry, it is clear that this fuel source is more than just a temporary alternative. It represents a concerted effort to balance operational demands with environmental responsibilities. The ongoing development in CNG technology and infrastructure will play a crucial role in shaping the future of heavy-duty transport, making it a worthwhile consideration for both fleets and investors alike.
