Volvo trucks are currently in on-road testing as announced by Volvo Trucks on April 1st. The European certified commercial launch is targeted to happen before 2030.

Building on the proven HPDI fuel system technology in LNG-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.
