Westport- - Model H2 HPDI™ - High Pressure Direct Injection Technology

PRACTICAL
Vehicle performance is critical for fleet managers, who are limited in the compromises they can make to advance sustainability.

EFFICIENT
H2 HPDI™ fuel system equipped engines can exceed the performance of current heavy-duty diesel vehicles, while almost eliminating greenhouse gas emissions.

ROBUST
The H2 HPDI™ fuel system is a robust solution that doesn’t require extremely pure hydrogen to run, unlike fuel cells.

COST EFFECTIVE
H2 HPDI™ fuel system equipped engines deliver higher performance than spark ignition H2 ICE: significantly higher efficiency and power density; lower operating cost.

H₂ HPDI™ fuel system equipped engines offer far greater CO2  reductions for every Euro of public and private investment, compared to fuel cells. Based on Westport’s current technology, the H₂ HPDI™ fuel system avoids reliance on the sensitive and expensive minerals used in fuel cell catalysts and batteries, resulting in far lower cost base than fuel cells.

The marginal cost of the additional NO_X reductions that come from using fuel cells far exceeds the societal cost of NO_X emissions.

H₂ HPDI™ fuel system equipped engines optimized to run on hydrogen offer many advantages over other pathways, enabling an accelerated adoption of hydrogen as part of a sustainable road freight system.
