VANCOUVER, British Columbia, April 01, 2026 (GLOBE NEWSWIRE) -- Westport Fuel Systems Inc. ("Westport" or the “Company”) (TSX:WPRT / Nasdaq:WPRT), a leading supplier of advanced alternative fuel systems and components for the global transportation industry, is pleased to announce that its joint venture, Cespira and their HPDI™ fuel system technology will be utilized by Volvo AB in on-road testing of heavy-duty trucks powered by hydrogen. Volvo has indicated that a commercial launch is planned to take place prior to 2030.

“On-road testing is a key milestone in demonstrating that Cespira’s hydrogen HPDI fuel system is a cost-effective solution that operates on a zero-carbon fuel while delivering best-in-class power, torque, and efficiency,” said Dan Sceli, Chief Executive Officer of Westport. “Hydrogen use in an internal combustion engine with Cespira’s HPDI fuel system delivers nearly 100% CO2 reductions over diesel fueled trucks while allowing OEMs to preserve their existing engine architecture, leverage existing engineering talent and experience, installed investments, and decades of technology development in vehicle powertrain design, supply chain, and manufacturing.”

Cespira’s HPDI fuel system, running on LNG and bioLNG, is a well-established and reliable commercial platform. It is used in over 10,000 Volvo LNG trucks worldwide. The hydrogen powered version of HPDI uses fundamentally the same system that has been proven for LNG with a few small variations. Hydrogen HPDI is a high-performance solution to support climate neutrality in the heavy-duty mobility sector that is capable of being classified as a Zero Emissions Vehicle under the EU CO2 emissions standards. Moreover, hydrogen can be produced from different feedstock than fossil fuels. For example, green hydrogen is created from water. This makes hydrogen a promising option to deliver energy security and independence in various regions around the world and positioning it as an attractive fuel for the future.
