Cummins Inc. Leader Sees Promise for No-Carbon, Hydrogen-Fueled Internal Combustion Engines

The President of Cummins Inc.’s Engine business segment says hydrogen-fueled internal combustion engines (ICEs) hold tremendous potential in the effort to address the world’s climate challenges.

“Hydrogen ICEs will provide a low-cost, zero-carbon solution for high load factor and high utilization applications where battery-electric solutions cannot meet the operational requirements and fuel cells are not yet economically viable,” Srikanth Padmanabhan wrote in a blog appearing recently on the global power leader’s website.

“Likewise, launching the hydrogen engine also benefits other paths to reach a zero-carbon future, such as hydrogen fuel cells,” he added. “By creating a viable use case and demand for hydrogen in the near term, we can accelerate hydrogen infrastructure build-out and increase scale production of vehicle storage tanks. Both advances are necessary for the widespread adoption of fuel cell powertrains.”

More work on hydrogen-fueled internal combustion engines is necessary to “match the performance capability to the powertrain with the applications most struggling to find viable zero-carbon solutions in the near term,” the Cummins executive wrote.

But he noted the company has extensive expertise in both internal combustion engines and bringing new technologies to market.

Hydrogen-fueled internal combustion engines burn fuel in much the same way gasoline is used in an engine. Hydrogen-fueled engines tend to be most efficient when under high load, such as heavy-duty trucks hauling heavy freight. Commercial vehicles that frequently operate without any load, say tow trucks, may be better initial candidates for hydrogen fuel cells.

Cummins wants to be a leader in addressing the world’s climate challenges. The company is working to reduce the carbon produced by its more traditional products such as internal combustion engines through low-carbon fuels and by other means to achieve carbon savings relatively quickly. 

It’s also bringing to market electrified platforms like hydrogen fuel cells that produce little or no-carbon. It will likely take longer for mass adoption of these new technologies as the infrastructure develops to support them.
