Westport (Nasdaq: WPRT) ramps up hydrogen and alt-fuel component production

Rhea-AI Filing Summary

Westport Fuel Systems Inc. reports that production has begun at two key high-pressure fuel system facilities: its expanded product development and manufacturing site in Cambridge, Ontario, and its new China Hydrogen Innovation Center and manufacturing facility in Changzhou, China. Initial products were shipped to customers in December 2025, and both sites are expected to continue ramping up capacity through the first quarter of 2026.

The facilities support Westport’s GFI-branded high-pressure controls and systems business, which designs and manufactures safety-critical components such as regulators, valves, and pressure relief devices for hydrogen and other alternative fuel systems. The new China facility is aimed at serving a broad range of hydrogen applications, including commercial vehicles, buses, trains, marine, material handling, and stationary power, while the expanded Cambridge site strengthens Westport’s North American innovation and engineering hub. Management frames these moves as aligned with its growth strategy in hydrogen, CNG, and RNG technologies.

Insights

Clean transportation & industrials analyst

Westport expands global hydrogen and alternative fuel component production capacity.

Westport is scaling its High-Pressure Controls and Systems business by starting production at an expanded Cambridge, Ontario facility and a new hydrogen-focused plant in Changzhou, China. These sites support GFI-branded regulators, valves, and pressure relief devices used across automotive, truck, bus, and industrial markets, with initial shipments already made in December 2025 and further ramp-up through Q1 2026.

The China facility targets what is described as the world’s largest hydrogen transportation market, supplying components for commercial vehicles, buses, trains, marine, material handling, and stationary power generation. The Cambridge expansion reinforces Westport’s North American innovation hub, potentially improving engineering responsiveness and logistics for regional OEM customers.

While this represents a strategic manufacturing expansion in high-growth hydrogen and alternative fuel segments, the information provided does not quantify capital spending, capacity, or revenue contribution. The ultimate impact will depend on customer adoption of hydrogen and natural gas technologies and Westport’s ability to execute the production ramp and win additional OEM programs in these applications.

Westport Announces Start of Production at Two Key High-Pressure Controls and Systems Facilities

~  Global Production Expansion Strengthens Hydrogen and Alternative Fuel System Manufacturing Capacity  ~

VANCOUVER, British Columbia, Jan. 19, 2026 (GLOBE NEWSWIRE) -- Westport Fuel Systems Inc. (“Westport") (TSX:WPRT / Nasdaq: WPRT), a supplier of alternative fuel systems and components for the global transportation industry, announces the commencement of production at its expanded product development and manufacturing facility in Cambridge, Ontario and its new China Hydrogen Innovation Center and Manufacturing facility in Changzhou, China. Both facilities will support the development of Westport’s GFI-branded fuel system components by advancing Westport’s global hydrogen, CNG and RNG strategies and enabling local manufacturing capacity in China, a market widely cited as the largest in the world for hydrogen commercial vehicle deployment, with Chinese sales of hydrogen buses and trucks exceeding those of all other regions combined in 2024. Initial products were shipped to customers in December 2025, with both facilities continuing to ramp up capacity through the first quarter of 2026.
