Cummins has been conducting proof-of-concept testing of a hydrogen-fuelled internal combustion engine, with plans to evaluate the engine in a variety of on- and off-highway applications.
The hydrogen engine can use green hydrogen fuel, produced by Cummins-manufactured electrolysers, emitting near zero CO2 emissions through the tailpipe and near zero levels of NOx. The projected investment in renewable hydrogen production globally will provide a growing opportunity for the deployment of hydrogen-powered fleets utilizing either Cummins fuel cell or engine power.
Cummins is investing across a range of technologies to support hydrogen-based transportation including hydrogen engines, fuel cells, electrolysers and storage tanks. The high energy density of hydrogen enables easily integrated on-board gas storage without compromising either the vehicle payload or operating range. Cummins’ joint venture partnership with hydrogen storage specialist NPROXX adds the ability to integrate the fuel cell or hydrogen engine with the high-pressure gas cylinder tanks and supply lines on the vehicle. NPROXX is also a leading supplier of containerized storage vessels, enabling fast hydrogen refuelling for end users.
Srikanth Padmanabhan, president of the engine segment, 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.”
Jonathon White, vice-president of engine business engineering, Cummins, said: “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.”
Cummins role in expanding the hydrogen ecosphere goes beyond fuel cells and storage solutions to the manufacture of decarbonized renewable hydrogen, with the experience of more than 600 electrolyser installations across the globe. The modular scalability of its electrolysers are suited to a range of applications, from the localized supply of truck and bus fleets to utility-scale electrolysis.
