Westport Fuel Systems & AVL conclude high-efficiency H2 powertrain can outperform fuel cells in TCO for heavy-duty applications
A model-based analysis by Westport Fuel Systems and AVL indicates that H
2-HPDI (High Pressure Direct Injection with pilot ignition) a combustion approach for hydrogen in engines has the potential to achieve fuel economy close to that of a fuel-cell electric vehicle (FCEV) for heavy duty applications, due to its high efficiency at both part and full loads.
In a joint publication, WFS and AVL conclude that the combined high efficiency and lower system costs relative to FCEVs make H
2-HPDI the most capital efficient means to use hydrogen and lower CO
