Hyundai Doosan Infracore has rolled out the prototype of its new hydrogen internal combustion engine. The 11-litre engine produces a power output of 300kW (402 HO) and a torque of 1700 Nm at 2000 RPM.
The engine passed 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) and Zero Impact Emission (Zero Emission in EU).
Powered by low-purity hydrogen, the engines are durable, economical and energy-dense, which makes them the most suitable engine system for mid-to-large-sized vehicles and vehicles for long distances. A 10 minute charge 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.
HDI plans to leverage its existing engine technology and facilities to reduce costs and accelerate commercialisation. The new hydrogen engines will be installed on commercial vehicles such as trucks and large buses, and construction equipment for validation by 2024, and 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 realise carbon neutrality in response to the eco-friendly market by developing green hydrogen-related technologies in line with increasingly strict carbon emission regulations.”
HDI will showcase various products including H2ICE, EV battery packs and plug-in full hybrid powertrains at the CONEXPO 2023 to be held in the US in March.
