HPDI H2

Our HPDI H2 fuel system technology is a cost effective, high performance solution to support climate neutrality in the heavy-duty mobility sector.

HPDI H2 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.

Performance

Practical
HPDI H2 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.
Efficient
HPDI H2 fuel system equipped engines can exceed the performance of current heavyduty diesel vehicles, while almost eliminating greenhouse gas emissions.
Robust
The HPDI H2 fuel system is a robust solution that doesn’t require extremely pure hydrogen to run, unlike fuel cells.
Cost effective
HPDI H2 I fuel system equipped engines deliver higher performance than spark ignition H2 ICE: significantly higher efficiency and power density; lower operating cost.

Cost

HPDI H2 fuel system equipped engines offer far greater CO2 reductions for every Euro of public and private investment, compared to fuel cells. Based on HPDI’s current technology, the HPDI H2 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 NOX reductions that come from using fuel cells far exceeds the societal cost of NOX emissions.

Market readiness

HPDI solutions are more cost effective than fuel cells for CO2 abatement. HPDI H2 uses the same technology and shares many of its components with existing LNG HPDI powertrains. As a result, HPDI H2 can utilise existing manufacturing infrastructure, with reduced capital investments, thus expediting time to market. The rapid scaling of production means that HPDI can be quickly deployed, stimulating the demand for hydrogen, and accelerating the reduction of cumulative GHG emissions.
