Cummins Testing Hydrogen-Fueled Internal Combustion Engine

Global power leader Cummins is taking another step forward in advancing zero carbon technology as the company begins testing a hydrogen-fueled internal combustion engine.

The proof-of-concept testing builds on Cummins’ existing technology leadership in gaseous-fuel applications and powertrain leadership to potentially create new low-carbon power solutions that help customers meet the energy and environmental needs of the future.

“Cummins is thrilled about the potential of the hydrogen engine to reduce emissions and provide power and performance for customers,” said Srikanth Padmanabhan, President of the company’s Engine business segment. “We are using all new engine platforms equipped with the latest technologies to improve power density, reduce friction and improve thermal efficiency, allowing us to avoid the typical performance limitations and efficiency compromises associated with converting diesel or natural gas engines over to hydrogen fuel.”

Following the proof-of-concept testing, the company plans to evaluate the engine in a variety of on- and off-highway applications, supporting Cummins’ efforts to accelerate the decarbonization of commercial vehicles.

“The hydrogen engine program can potentially expand the technology options available to achieve a more sustainable transport sector, complementing our capabilities in hydrogen fuel cell, battery electric and renewable natural gas powertrains,” said Jonathon White, Vice-President of Engine Business Engineering.

Renewable hydrogen production globally could provide a growing opportunity for the deployment of hydrogen-powered fleets utilizing either fuel cell or engine power. Cummins wants to offer customers a broad portfolio of power solutions, so they have the power to choose what works best for their situation and sustainability goals.
