Cummins progressing with H2 combustion engine development

According to Cummins, its hydrogen-fueled internal combustion engine (H2-ICE) program is ready to move ahead, with the development of a medium-duty 6.7-liter and a heavy-duty 15-liter engine. Based on next-generation platforms, the aim of the new hydrogen engines is to achieve zero carbon emissions, enhanced power density and improved thermal efficiency.

The new 15-liter platform offers the potential to bring hydrogen gas-fueled engine capability to long-haul trucks and other heavy-duty applications.
