Westport signs third global heavy-duty OEM collaboration agreement to demonstrate H2 HPDI fuel system on IC engine platform

Westport Fuel Systems is collaborating with a global original equipment manufacturer (OEM) to evaluate the performance, efficiency and emissions of the OEM’s engine equipped with Westport’s H2 HPDI fuel system. This collaboration marks Westport’s third major OEM engagement evaluating its H2 HPDI fuel system to date. Funded by the OEM, the work starts immediately and continues through year end.

Vehicle makers around the world are recognizing that there are many possible paths to reaching the important goal of significantly reducing or eliminating emissions. Demonstrating our H2 HPDI fuel system is the first step on the path to commercialization and supports the growing view that a ‘one size fits all’ approach to emissions reduction does not exist. Maintaining existing diesel engine architectures and related manufacturing infrastructure is critical to enabling OEMs to offer timely, efficient, cost-effective peak performance in transport applications.

—David M. Johnson, CEO of Westport Fuel Systems

Hydrogen use in an internal combustion engine with Westport’s H2 HPDI fuel system offers a cost-effective solution that delivers substantial CO2 reductions 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.

Westport’s production HPDI system fueled with LNG and bioLNG is a mature and proven commercialized platform, providing a solid foundation to develop the hydrogen-fueled version of the HPDI system.

This collaboration is designed to demonstrate that Westport’s H2 HPDI fuel system is a cost-effective solution that delivers significant CO2 abatement while achieving power, torque, and efficiency that exceeds the performance of a diesel engine.



If i were a trucker i would be interrested to buy. But as a car driver im interrested to buy a small hydrogen ice car and be fully carbon neutral as engine oil last longer. Also tires and brakes last long on a lighter car.



Very valid points about tires and brakes lasting longer on a much lighter ICE vehicle vs a heavy BEV of similar passenger capacity and cargo space. I leased a Model S it absolutely ate tires every 15-20,000 miles expensive low profile tires at that. It got replaced with a full sized Kia sedan that just went 107,000 miles on a set of Kumho low pros. The neat thing about direct hydrogen/ngas injection engines is that theu can use either fuel and a mix of both in any ratio from 0 to 100% of either with modern ECUs and close loop wide range O2 sensors. Why a mix you ask? Because at a given tank storage pressure and volume be it 300bar or 700bar natural gas will have THREE times the energy content in that volume at equal pressures vs H2 gas. This means you can go three times farther on a tank of natural gas vs H2. The obvious choice is to use H2 gas for local driving and return to depot type fueling or for retail or home use a micro electrolysis system using off peak power or solar power from a roof top array while the owner is away during the day. For long distance trips fill the pressure tank with natural gas and triple your range. If it makes you feel better use landfill gas or synthetic natural gas from CO2 and H2 like Audi is making. Either way gas fuel ICE engines run so clean they qualify as Tier 3 bin Zero EPA ratings and CARB ZEV ratings that's equal to a zero emissions vehicle. The added benefit is engines oils last for twice to four times as long it's worth using analytical oil testing to determine oil life remaining vs fixed change intervals.
