VANCOUVER, British Columbia, Feb. 25, 2021 (GLOBE NEWSWIRE) -- Westport Fuel Systems Inc. ("Westport Fuel Systems") (TSX/Nasdaq: WPRT) a global leader in alternative fuel, low-emissions transportation technologies today released a joint publication with AVL, the world's largest independent company for the development, simulation and testing of powertrain systems, entitled "Total Cost of Ownership (TCO) Analysis for Heavy Duty Hydrogen Fueled Powertrains."

The analysis presents the case for Hydrogenand on AVL's website here.

"Our analysis shows that a high efficiency hydrogen ICE powertrain (namely H₂-HPDI) can outperform fuel cell electric vehicles in terms of TCO. This is possible because H₂-HPDI leverages powertrain systems in high volume production today, while achieving near fuel cell-like efficiency in heavy duty applications," said David Johnson, CEO of Westport Fuel Systems. "Fleets will appreciate a product that meets the same performance characteristics of today's conventional diesel trucks without the product development risk and costs associated with fuel cells. HPDI 2.0 is already used by large fleets today, reducing CO₂ by 23% with fossil LNG, and delivering net zero carbon emissions when used with bioLNG."

Hydrogen plays an effectual role in the decarbonizing of a wide range of carbon-emitting activities. It has the adaptability to operate cleanly across the transport, heat, industry and electricity sectors, which together account for around two-thirds of global carbon dioxide emissions.
