Westport Reveals CNG Solution For Natural Gas HPDI Engines And North America’s Clean Transportation Future

Innovative and proprietary solution aims to set a new standard for high-efficiency performance while delivering superior economics and flexibility to operate on natural gas and renewable natural gas (RNG) as well as blends of natural gas, RNG, and hydrogen.

VANCOUVER, British Columbia, Nov. 06, 2025 (GLOBE NEWSWIRE) -- Westport Fuel Systems Inc. ("Westport") (TSX:WPRT / Nasdaq: WPRT), a supplier of alternative fuel systems and components for the global transportation industry, today announces a breakthrough solution designed to dramatically expand the addressable market for HPDI™ while significantly improving the affordability and performance of heavy-duty natural gas trucks in many markets globally. Westport’s compressed natural gas (CNG) solution, when combined with the on-engine HPDI™ fuel system of Cespira, Westport’s joint venture with the Volvo Group, is designed to enable fleet operators to achieve diesel-like performance at a lower total cost of ownership and reduce or even eliminate greenhouse gas emissions.

The HPDI system has been commercially available for several years as a liquefied natural gas (LNG) solution. This LNG HPDI technology is now operating in more than 30 countries, powering over 9,000 trucks worldwide. However, in many markets with extensive pipeline infrastructure and abundant natural gas resources—particularly in North America—Westport believes that a CNG solution is a better fit than LNG. Until now, CNG has not been an option for the HPDI system.

Westport is revealing today a proprietary CNG solution that leverages advanced high-pressure storage technology, designed to deliver the performance required for HPDI. This breakthrough enables faster time-to-market for CNG-powered HPDI applications and prioritizes reduced lifecycle costs by optimizing system design. The new platform will expand HPDI’s reach to markets that require a CNG-based solution, enhancing its accessibility and economic advantages. Field testing for Westport’s CNG solution is expected to begin in 2026, with the path to commercialization expected to follow.

Dan Sceli, Chief Executive Officer of Westport, said: “Westport is redefining what’s possible for natural gas-powered transportation. Our goal has always been to deliver practical, affordable, and scalable solutions for fleets that need reliability and performance without compromising sustainability. We believe that CNG with HPDI will give operators a clear advantage over other low-carbon technology options—helping fleets reduce costs, cut emissions, and stay competitive in a changing market.”

“Conventional and renewable natural gas are among the cleanest, most affordable, and scalable motor fuels,” said Daniel Gage, President of The Transport Project, a Washington DC-based coalition of North American fleets, equipment and engine manufacturers, fuelers, and fuel producers that advances the growth and deployment of practical, clean, gaseous fuels for commercial transportation. “The use of renewable natural gas in transportation has grown by 93% in the past five years. Westport’s CNG solution will introduce a new natural gas technology for the North American market, which along with CNG’s low cost and stable pricing, will increase product options for commercial fleets and further the case for natural gas as the best alternative to diesel.”

Westport is already operating on the road. An engineering truck equipped with a CNG system in Vancouver, Canada, is showcasing some of the potential of the technology’s real-world performance and fuel efficiency. Additionally, the Company plans to have demonstration trucks with the full proprietary CNG system operating in real-world fleet applications in 2026, as Westport expands customer demonstration programs to validate the system’s benefits under diverse operating conditions.

Brad Fedora, President & CEO at Trican Well Services Ltd., said: “We are encouraged by this initiative by Westport. This appears to be a practical step toward delivering lower prices at the pump while also lowering emissions in the heavy-duty transport sector, all without compromising the power, reliability, or efficiency of compression ignition. Trican owns hundreds of heavy-duty trucks, which are on the road every day, and our demanding operating conditions, where diesel-like performance is essential, need a solution where we don’t have to choose between performance and sustainability. Trican will be following the development of this HPDI system for CNG in real-world conditions typical of our industry.”

“We are also encouraged by the federal government’s continued commitment—reaffirmed in Budget 2025 through Canada’s Climate Competitiveness Strategy—to strengthen Canadian leadership in a low-carbon economy,” added Sceli. “The Budget confirms ongoing support for clean hydrogen, renewable natural gas, and other bio-based energy solutions through Clean Economy Investment Tax Credits and clean-growth programs. These measures reinforce Canada’s transition toward net-zero by 2050 and pave the way for greater adoption of innovative low-carbon technologies such as ours.”
