Automotive Hyundai, hydrogen on a dual path

Redazione

Despite the challenges linked to integrating hydrogen into automotive propulsion systems, Hyundai continues to refine both its fuel cell systems and hydrogen internal combustion engines. These two parallel lines of development combine technological innovation with real-world industrial applications Over recent years, hydrogen has taken on an increasingly central role as an alternative energy carrier, emerging as one of the most promising solutions for reducing emissions in the automotive sector and giving rise to two distinct yet complementary technological directions: on one hand, fuel cell propulsion, and on the other, the…

Kubota’s two stands at Bauma 2025 were full of upgrades and innovations. The Japanese manufacturer showcased its hydrogen engine once again, updated the performance of the four-cylinder “V3307” and “V5009” engines, and introduced a new sensor for analyzing HVO fuels. Making its world debut was the twin-cylinder “Z482K,” compliant with Euro 5+ emissions standards, designed for on-road applications In Kubota’s off-road engine lineup, there had been a gap in the five-liter high-power range. For instance, the company’s 175-horsepower “M7004” agricultural tractor is powered by the six-cylinder “V6108.” At Bauma, Kubota…

In the aerospace sector, the decarbonization of propulsion systems is increasingly turning toward hydrogen as a viable alternative fuel for thermal engines. While this approach presents several engineering challenges, it offers the potential to match the performance and range of conventional fossil fuel-powered engines In recent years, the aviation industry has significantly accelerated the development of hydrogen-based propulsion technologies, aiming to replace fossil-derived fuels in thermal engines. Although hydrogen is often associated with electrified propulsion through fuel cells, its use as a direct combustion fuel offers a major advantage: the…
