Westport Fuel Systems Inc, a global leader in alternative fuel transportation technologies, announced today a collaboration with Johnson Matthey, a global leader in sustainable technologies, to develop an emissions aftertreatment system tailored to Westport’s proprietary H2 HPDITM hydrogen fuel internal combustion engine.


The collaboration focuses on merging Johnson Matthey’s technologies and products with Westport’s H2 HPDI fuel system to achieve the lowest feasible exhaust emissions from vehicles. Westport will test and develop the Johnson Matthey prototype system in partnership with the company’s engineering centre in Vancouver, Canada.

“This joint effort is a natural fit as we are both working toward zero emissions solutions for affordable and cleaner transportation that do not compromise performance or efficiency,” said David M. Johnson, Chief Executive Officer of Westport Fuel Systems. “We are pleased to be partnering with Johnson Matthey, driving cleaner performance together, by optimizing our hydrogen HPDI fuel system running on zero-carbon hydrogen for heavy-duty transportation.”

Hydrogen internal combustion engines (ICE) have the potential to broaden the technology alternatives available for achieving a more sustainable transportation future, complementing Johnson Matthey’s hydrogen fuel cell capabilities. For commercial vehicles, where the route to fuel-cell and battery-electric powertrains is still in its early stages of development, hydrogen ICE will be a significant supplement to these technologies, particularly in heavier load and greater horsepower applications. Furthermore, hydrogen ICE will be able to fulfil stringent pollution and CO2 regulations.

“Heavy-duty transportation is crucial for the movement of goods so it’s important we’re able to do this as sustainably as possible,” said Andy Walker, technology market insights director at Johnson Matthey. “As a leading manufacturer of emissions controls systems for the last 50 years, we’re excited to be combining our expertise with Westport to make commercial transportation clean and fit for the future.”
