Westport announced Thursday that it is bringing its next-generation compressed natural gas (CNG) fuel storage and delivery system to ACT Expo 2026. The announcement marks the first North American demonstration of the technology, which the company says can match diesel performance while running on widely available CNG.

The system will be showcased at the May 4-7 event in Las Vegas on a Volvo VNL 300 heavy-duty truck that produces 500 horsepower and 1,850 pound-feet of torque, with fuel efficiency closely comparable to that of diesel-powered models. The demonstration represents what Westport calls a critical step toward commercializing high-pressure direct injection (HPDI) technology for the North American market.

“Showcasing our next-generation high-pressure CNG system at ACT Expo marks a defining milestone for the future of clean transportation,” said Dan Sceli, chief executive of Westport. “By combining advanced high-pressure storage with Cespira’s proven HPDI fuel systems, we’re demonstrating that fleets can achieve diesel performance and efficiency using widely available natural gas.”

The HPDI fuel system is managed through Cespira, a joint venture between Westport and Volvo Group launched about a year and a half ago. The technology is already commercially available in more than 30 countries, powering over 10,000 trucks worldwide using liquefied natural gas.
