Westport’s Hydrogen HPDI System Enters On-Road Testing with Volvo

Event summary

  • Westport’s hydrogen HPDI™ fuel system, developed by its joint venture Cespira, is now in on-road testing with Volvo for heavy-duty trucks.
  • Volvo plans a commercial launch of hydrogen-powered trucks before 2030.
  • The system aims to deliver near 100% CO2 reductions over diesel while leveraging existing engine architectures.
  • Cespira’s HPDI technology is already used in over 10,000 Volvo LNG trucks globally.

The big picture

Westport’s hydrogen HPDI system represents a strategic pivot toward zero-emission heavy-duty transport, aligning with global decarbonization mandates. The technology’s ability to integrate with existing engine architectures could accelerate adoption, but success hinges on overcoming infrastructure and cost barriers. Volvo’s involvement signals industry validation, though broader market acceptance remains uncertain.
