\n Westport\u2019s next\u2011generation compressed natural gas fuel storage system, combined with Cespira’s on-engine HPDI\u2122 fuel system, marks a major step toward commercializing heavy-duty trucks with diesel performance and efficiency using widely available compressed natural gas<\/em>\n <\/p>\n

VANCOUVER, British Columbia, April 30, 2026 (GLOBE NEWSWIRE) — Westport<\/u><\/a> (TSX:WPRT \/ Nasdaq:WPRT), a global leader in advanced alternative fuel systems for the transportation industry, today announced the first North American demonstration of its compressed natural gas (CNG) fuel storage system combined with the on-engine HPDI\u2122 fuel system of Cespira, Westport\u2019s joint venture with Volvo Group, at ACT Expo 2026<\/u><\/a>, taking place May 4-7 in Las Vegas. These systems are installed on a latest-generation Volvo VNL 300 truck with 500 horsepower and 1,850 lb-ft of torque, and with fuel efficiency on CNG closely comparable to the VNL running on diesel fuel.<\/p>\n

For the first time, Westport is showcasing the system in real\u2011world operation in a demonstration truck. This marks a critical step toward commercializing HPDI technology with CNG for the North American heavy\u2011duty market, where CNG is preferred and demand for practical, cost-effective, lower\u2011emission diesel alternatives continues to grow.<\/p>\n

Westport\u2019s high\u2011pressure (~700 bar) CNG platform is engineered for diesel combustion engines that require in\u2011cylinder, high\u2011pressure gaseous fuel injection, including engines equipped with the HPDI fuel system developed by Cespira. While HPDI is commercially available in more than 30 countries, powering over 10,000 trucks worldwide using liquefied natural gas (LNG), North America\u2019s preference for CNG has limited adoption in this market. Westport\u2019s new fuel storage system removes that barrier.<\/p>\n

\u201cShowcasing our next\u2011generation high\u2011pressure CNG system at ACT Expo marks a defining milestone for the future of clean transportation,” said Westport CEO Dan Sceli. \u201cBy combining advanced high\u2011pressure storage with Cespira\u2019s proven HPDI fuel systems, we\u2019re demonstrating that fleets can achieve diesel performance and efficiency using widely available natural gas. This is more than a product introduction\u2014it\u2019s a meaningful step toward delivering real emissions reductions with compelling operating economics for the North American market.\u201d<\/p>\n

\n Westport debuts its high-pressure CNG fuel system with Cespira HPDI\u2122 technology on a Volvo VNL 300 at ACT Expo 2026, delivering clean fuel power and diesel efficiency with lower emissions for Noth American heavy-duty fleets.<\/em>\n <\/p>\n

\n Building a New Pathway for Hydrogen<\/em>

The HPDI fuel system has the unique ability to be applied and certified to run on a variety of different fuels with minimal hardware changes, including natural gas, hydrogen or a blend of both fuels. OEMs can integrate NG HPDI in the near term and subsequently leverage their existing HPDI engineering and manufacturing investments to extend the technology to other fuels as needed. Unlike fuel cells, an engine equipped with the HPDI fuel system does not require hydrogen to be 99.999% pure. This means hydrogen for HPDI-equipped engines does not need a dedicated, super-clean distribution system and can avoid the high cost of liquefying hydrogen and transporting it in cryogenic trailers. Westport believes that the fuel adaptability of the HPDI on-engine fuel system will provide a more practical path for the use of hydrogen in heavy-duty transportation.<\/p>\n
