Hyundai Doosan Infracore (HDI) has finished the design of its hydrogen internal combustion engines and will soon begin rolling out the prototype.

The 11-litre class hydrogen engine under development by HDI produces a power output of 300kW and a torque of 1700 Nm at 2000 RPM. It satisfies Tier 5 / Stage 5 / Euro 7 regulations, which require the emission to be 90% reduced to the current level to meet Zero CO2 (below 1g/kwh).

Hydrogen engines are powered by low-purity hydrogen, making them durable, economical and energy-dense. A single charge of ten minutes enables a distance of up to 500 km, and they are 25-30% more economical than fuel cells or battery packs when vehicle price and maintenance costs are considered.

 The new hydrogen engines will be installed on commercial vehicles such as trucks, large buses and construction equipment for validation by 2024. Full-scale mass production is planned for 2025.

HDI’s Head of the Engine Department, Kim Joong-soo, said: “Hydrogen internal combustion engines will be used in mid-to-large-sized commercial vehicles such as trucks, buses and construction equipment and mid-to-large-sized power generators. We will put in the utmost effort to realize carbon neutrality in response to the eco-friendly market by developing green hydrogen-related technologies in line with increasingly strict carbon emission regulations.”
