Prototype roll out this year, on-vehicle validation in 2024, full-scale mass production in 2025
HYUNDAI Doosan Infracore (HDI) are accelerating engine development after completing the design of their hydrogen internal combustion engines (hydrogen ICEs) and rolling out the prototype.
The hydrogen engine under development by HDI is an 11-litre-class engine that produces a power output of 300kW (402hp) and a torque of 1,700Nm at 2,000 rev/min. It satisfies Tier 5 / Stage V / Euro 7 regulations which require the emission level to be 90% reduced from the current level to meet Zero CO2 (below 1g/kWh) and Zero Impact Emission (zero emission in the EU).
Hydrogen engines are powered by low-purity hydrogen, making them durable, economical and energy-dense, and therefore the most suitable engine system for mid-to-large-sized vehicles and vehicles for long distances. A single charge of 10mins enables a distance of up to 500km, and they are 25–30% more economical than fuel-cells or battery packs when vehicle price and maintenance costs are taken into consideration.
HDI say they plan to leverage their existing engine technology and facilities to reduce costs and accelerate commercialization. The new hydrogen engines will be installed on commercial vehicles such as trucks and construction equipment for validation by 2024, with full-scale mass production planned for 2025.
The company will showcase various products including H2ICE, EV battery packs and plug-in full-hybrid powertrains at next month’s Conexpo show in Las Vegas.
Kim Joong-soo, head of HDI’s engine department, said: ‘Hydrogen internal combustion engines will be used in mid-to-large-sized commercial vehicles such as trucks and construction equipment and in 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.’
