Cummins testing hydrogen-fuelled internal combustion engine

Cummins has begun testing a hydrogen-fuelled internal combustion engine. The proof-of-concept test is designed to assess new power solutions to 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,” says Srikanth Padmanabhan, president of the engine segment, Cummins. “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.”

Following the proof-of-concept testing, the company plans to evaluate the engine in a variety of on- and off-highway applications, supporting its efforts to accelerate the decarbonisation 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,” adds Jonathon White, vice-president of engine business engineering.

The hydrogen engines can use green hydrogen fuel, produced by Cummins-manufactured electrolysers, emitting near zero CO2 emissions through the tailpipe and near zero levels of NOx. Cummins is investing across a range of technologies to support hydrogen-based transportation including hydrogen engines, fuel cells, electrolysers and storage tanks.
