Cespira, the joint venture between Westport Fuel Systems and Volvo Group, has signed a development agreement with Volvo Group to finalize the integration and commercialization of Cespira's HPDI fuel system technology for Volvo Group's 13-litre engine to run on hydrogen. Volvo trucks are currently in on-road testing, and the European certified commercial launch is targeted before 2030. The HPDI system enables direct injection of alternative fuels at high pressures, delivering diesel-equivalent performance with zero-carbon hydrogen while tolerating a range of hydrogen fuel compositions, a significant advantage over fuel-cell systems. Mehdi Ferhan, Senior Vice President of Powertrain Technology at Volvo Group, said the project reflects Volvo's commitment to low-carbon solutions and confidence in the joint venture, while Cespira President and CEO Carlos Gonzalez highlighted the technology's ability to support better economics and allow OEMs to adapt trucks to regional fuel realities using a common engine platform.
