Cummins tests hydrogen-fueled internal combustion engine

Cummins will start testing a new hydrogen-fueled internal combustion engine , which will help meet future energy and environmental needs.

Following the proof-of-concept testing, the company wants to study the engine in a number of on- and off-highway applications, supporting Cummins’ efforts to expedite commercial vehicle decarbonisation.

Cummins claims that green hydrogen fuel produced by Cummins-manufactured electrolysers may be used in hydrogen engines, resulting in near-zero carbon emissions and NOx levels at the tailpipe.

Global investment in renewable hydrogen production is expected to increase, paving the way for the deployment of hydrogen-powered fleets powered by Cummins fuel cells or engines.

This is part of a larger investment in hydrogen-based transportation technology such as hydrogen engines, fuel cells, electrolysers, and storage tanks.

Because of hydrogen’s high energy density, on-board gas storage can be easily accommodated without sacrificing vehicle payload or operating range.

The joint venture with hydrogen storage specialist NPROXX allows the fuel cell or hydrogen engine to be integrated with the vehicle’s high-pressure gas cylinder tanks and supply lines.

Srikanth Padmanabhan, President of the Engine Segment at Cummins, said, “Cummins is thrilled about the potential of the hydrogen engine to reduce emissions and provide power and performance for customers.

“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.

“We have made significant technological advancements and will continue moving forward. We are optimistic about bringing this solution to market.”
