Hydrogen Engines for Heavy-Duty Vehicles

The companies Isuzu Motors, Denso Corporation, Toyota Motor Corporation, Hino Motors and the Commercial Japan Partnership Technologies Corporation (CJPT) have started planning and research on hydrogen engines for heavy-duty commercial vehicles with the aim of further utilizing internal combustion engines as one option to achieve carbon neutrality.


On the road to carbon neutrality, there are various powertrain options to meet customers’ demands, including HEVs, BEVs, and FCEVs, in accordance with the differences in energy conditions in different countries and diversified customer uses. Hydrogen engines are one such option. The hydrogen-powered Corolla has participated in the Super Taikyu Series since May 2021, and hydrogen engine technology is evolving. In addition, efforts toward achieving a hydrogen society are further accelerating, such as the increase in the number of partners in producing, transporting, and using hydrogen.


To reduce carbon emissions in transportation and logistics by heavy-duty commercial vehicles needs to be addressed. Isuzu, Denso, Toyota, Hino, and CJPT believe that hydrogen engines are one solution to this issue, and will utilize the technologies and know-how each company has accumulated to study the potential of hydrogen engines in heavy-duty commercial vehicles.
