CESPIRA, THE JOINT VENTURE BETWEEN WESTPORT AND VOLVO GROUP, SIGNS AGREEMENT WITH VOLVO GROUP TO COMPLETE HYDROGEN-FUELED ENGINE DEVELOPMENT

Cespira, Westport Fuel Systems Inc.'s joint venture with Volvo Group, and Volvo Group have signed a development agreement to finalize the integration and commercialization of Cespira's HPDI fuel system technology to enable Volvo Group's 13-litre engine to run on hydrogen. Volvo trucks are currently in on-road testing as announced by Volvo Trucks on April 1. The European certified commercial launch is targeted to happen before 2030.

Building on the proven HPDI fuel system technology in liquified-natural-gas-powered heavy-duty engines, this agreement governs the final development and commercialization activities to extend the 13L engine platform to run on hydrogen.

Cespira's HPDI fuel system enables direct injection of alternative fuels at high pressures into internal combustion engines, supporting the use of lower-carbon fuels while preserving the performance, durability and operating characteristics required for heavy-duty applications.

Applied to hydrogen, the technology is designed to deliver diesel-equivalent performance with a zero-carbon fuel, hydrogen. HPDI's unique tolerance to a range of hydrogen fuel compositions is a significant benefit over fuel-cell systems, which require highly pure hydrogen. Moreover, with heavy duty load cycles, HPDI running hydrogen has performance and efficiency that is competitive with fuel cell systems.

"This development project reflects Volvo Group's continued commitment to advancing low-carbon solutions for heavy-duty transport through multiple technology pathways. By partnering with Cespira on the hydrogen application of its HPDI fuel system technology to allow our 13-litre engine platform to run on hydrogen, we recognize the potential of hydrogen internal combustion as a viable long-haul option for fleets to reduce emissions in demanding applications. Our commitment to this program underscores the confidence we have in our JV, Cespira and in the long-term potential of HPDI fuel system technology," said Mehdi Ferhan, senior vice-president, powertrain technology, Volvo Group.

"Hydrogen HPDI is the next phase of our HPDI fuel system strategy. Its high tolerance to hydrogen purity and ability to blend with natural gas support better economics for all stakeholders, enabling fleets to reduce CO2 emissions with no trade-off in the performance they rely on. What is more, our HPDI development allows OEMs to adapt trucks to regional realities in fuel availability, price and infrastructure, while leveraging a common engine platform. This gives the industry cost-effective pathways to decarbonize today and builds optionality for other renewable fuels as the market evolves," added Carlos Gonzalez, president and chief executive officer of Cespira.

HPDI is a trademark of Cespira Canada LP, a Canadian limited partnership within the Cespira JV.
