Cummins Is Investing to Adapt an Internal Combustion Engine and Transform It into a Hydrogen-Powered Propulsion System
When it comes to hydrogen for powering vehicles, people often think of the use of fuel cells and complex systems that convert chemical reactions of hydrogen into electricity to power electric motors. However, some companies, such as Cummins, are exploring a simpler use of this fuel in an internal combustion engine. Since the fuel is a flammable gas, it could be used in appropriate internal combustion engines.

Cummins Hydrogen Engines May Expand Technology Options in the Automotive Industry
According to Jonathon White, vice president of Engine Business Engineering, the hydrogen engine program has great potential to expand the available technology options and achieve a cleaner transportation sector, alongside the company’s capabilities in hydrogen fuel cells, natural gas engines, and electric batteries.
The major advantage of using a hydrogen-powered internal combustion engine is that car owners and automakers will continue using vehicles equipped with existing transmission systems, able to operate in nearly every vehicle currently manufactured.
Additionally, Cummins’ hydrogen combustion engine will also be capable of using green hydrogen as fuel, which is produced by electrolyzers manufactured by the company with nearly zero CO2 emissions in the exhaust and levels approaching zero for NOx. The projected investment in global green hydrogen production will create growing opportunities for deploying hydrogen-powered fleets using Cummins’ fuel cell technologies or internal combustion engines.
