▶ Conducted driving test on Daegwallyeong ramp with large trucks... Completed verification of immediate ignition start and fuel supply stability;
▶ Final verification before mass production, including high temperature of 55℃ and durability test of 100,000km;
▶ Scheduled for mass production of engines in early 2026, hydrogen engine truck launch in first half of 2027

HD Hyundai Infracore has completed verification of the durability and stability of hydrogen engine vehicles in extreme frigid temperatures of -20 degrees Celsius.

On the 20th (Thursday), the company announced that it successfully completed the extreme climate test of an 11-liter hydrogen engine (HX12) in cooperation with Tata Daewoo Mobility in Daegwallyeong, Gangwon-do from the 4th to the 14th.

This test is designed to evaluate how well hydrogen engine vehicles demonstrate stable performance even in frigid temperature environments, and verified immediate ignition start, stable fuel supply in the hydrogen tank, slope drivability and braking under cargo loading conditions, and charging safety.

Based on the results of this test, HD Hyundai Infracore plans to conduct road driving tests with Tata Daewoo Mobility so as to improve the drivability and acceleration of hydrogen engine vehicles and measure emissions and fuel efficiency.

Additionally, the final tests leading up to mass production of hydrogen engine vehicles will be conducted, such as ▲ driving in hot climate ▲ measuring slope climbing capability ▲ testing in a 55℃ high-heat chamber (laboratory environment) ▲ testing driving durability of 100,000 km.

HD Hyundai Infracore will mass-produce hydrogen engines for trucks in early 2026, and supply them to Tata Daewoo Mobility. After that, it will embark on the commercialization stage, with the hydrogen engine truck to be released in the first half of 2027. This will mark the world’s first case of commercial vehicles, such as buses and trucks, being equipped with hydrogen engines.

The company's hydrogen engine was developed based on the CNG (compressed natural gas) engine for commercial vehicles, making it easy to install in conventional vehicles and more economical than other power sources that require high-purity hydrogen, such as hydrogen fuel cells. In recognition of this technological prowess, it won top honors of the 'Best Product Media Award' at the H2MEET 2024 hydrogen industry exhibition held in September last year.

HD Hyundai Infracore’s Jeong Wook, head of the Engine Product Development Division, said, "This frigid temperature test is an important process to verify the durability of our hydrogen engine technology," and added, "We will continue to accelerate technology development, ensuring that our hydrogen engines remain globally competitive in the eco-friendly mobility market."
