Keyou and Komatsu have collaboratively introduced a groundbreaking 12-cylinder, hydrogen engine-powered dump truck for the construction industry, marking a significant milestone in sustainable transportation. The companies are currently undergoing proof-of-concept tests at Komatsu's Ibaraki plant to assess various aspects of the vehicle, including driving performance, continuous operating hours, and fuel efficiency. Equipped with a 700 bar tank system provided by Argo-Anleg, the hydrogen-powered truck aims to maximize storage capacity. The project stems from a six-year partnership between the two firms, with the development of the hydrogen-powered truck commencing in 2023. The initial successful firing of the engine took place at Keyou's partner, KST, in Bad Dürkheim, Germany, with subsequent proof-of-concept tests officially starting in January 2025. Taisuke Kusaba, from Komatsu, emphasized the importance of this technology in reducing CO2 emissions and achieving climate neutrality goals. Furthermore, Komatsu has unveiled plans to significantly decrease CO2 emissions by 2030 and achieve full climate neutrality by 2050, with a strong focus on hydrogen technology as a key element of their carbon reduction strategy. The article also highlights the progress in the heavy-duty hydrogen-powered truck sector, with companies like Nikola and Cummins showcasing advancements. Nikola reported successful sales of its Class 8 TRE FCEV trucks and partnerships with major companies, while Cummins achieved a Guinness World Record for the longest distance traveled by a hydrogen FCEV truck without refueling. These developments underscore the growing momentum and potential of hydrogen-powered vehicles in the transition towards a more sustainable and efficient transportation sector.
