Awardees working on hydrogen combustion engine innovation include:
PACCAR. Development and demonstration of a heavy-duty hydrogen internal combustion engine.
Cummins. Development of a high-efficiency, low emissions, heavy-duty hydrogen internal combustion engine.
Powertrain. Development of a high-power, ultra-low emissions, heavy-duty hydrogen engine.
These internal combustion engine projects will support the use of hydrogen in the medium- and heavy-duty (MD/HD) transportation sector, thereby also supporting the use of hydrogen in MD/HD fuel cell vehicles, which have been identified as a key end use for clean hydrogen in the national clean hydrogen strategy.
The national strategy guides the priorities of the Hydrogen Interagency Task Force, which is coordinating a whole-of-government approach to advancing clean hydrogen. These efforts include tax incentives in the Inflation Reduction Act and ongoing research, development, and demonstration to drive down the cost of clean hydrogen and achieve the Hydrogen Shot goal of $1 per kilogram within a decade.
