Japanese OEMs collaborate on H2 engines for commercial vehicles

Isuzu Motors, DENSO, Toyota Motor, Hino Motors and Commercial Japan Partnership Technologies (CJPT) announced that they have started planning and foundational research on H2 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. H2 engines are one such option. The H2-powered Corolla has participated in the Super Taikyu Series since May 2021, and H2 engine technology is evolving. In addition, efforts toward achieving a H2 society are further accelerating, such as the increase in the number of partners in producing, transporting and using H2.

CO2 reduction in transportation and logistics by heavy-duty commercial vehicles, an important piece of infrastructure that supports people’s lives, is a social issue that needs to be addressed together with partners who share a common vision toward achieving a carbon neutral society. Isuzu, DENSO, Toyota, Hino and CJPT believe that H2 engines are one solution to this issue and will utilize the technologies and know-how each company has accumulated to study the potential of H2 engines in heavy-duty commercial vehicles.
