CESPIRA'S HYDROGEN HPDI™ FUEL SYSTEM NOW IN ON-ROAD TESTING

Westport Fuel Systems Inc.'s joint venture, Cespira, and its HPDI fuel system technology will be utilized by Volvo in on-road testing of heavy-duty trucks powered by hydrogen. Volvo has indicated that a commercial launch is planned to take place prior to 2030.

"On-road testing is a key milestone in demonstrating that Cespira's hydrogen HPDI fuel system is a cost-effective solution that operates on a zero-carbon fuel while delivering best-in-class power, torque and efficiency," said Dan Sceli, chief executive officer of Westport. "Hydrogen use in an internal combustion engine with Cespira's HPDI fuel system delivers nearly 100-per-cent CO2 reductions over diesel fuelled trucks 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."

Cespira's HPDI fuel system, running on LNG (liquified natural gas) and bioLNG, is a well-established and reliable commercial platform. It is used in over 10,000 Volvo LNG trucks worldwide. The hydrogen powered version of HPDI uses fundamentally the same system that has been proven for LNG with a few small variations. Hydrogen HPDI is a high performance solution to support climate neutrality in the heavy-duty mobility sector that is capable of being classified as a zero-emissions vehicle under the EU CO2 (European Union carbon dioxide) emissions standards. Moreover, hydrogen can be produced from different feedstock than fossil fuels. For example, green hydrogen is created from water. This makes hydrogen a promising option to deliver energy security and independence in various regions around the world and positioning it as an attractive fuel for the future.
