Cummins tests hydrogen engine
GLOBAL ENGINEMAKER CUMMINS IS WORKING ON both hydrogen fuel cell electric technology…and a hydrogen-fuelled internal combustion engine.
It says that it’s now doing proof-of-concept testing of the engine, which taps Cummins’“existing technology leadership”in gaseous-fuel applications and powertrain knowledge.
Cummins Engine Segment president Srikanth Padmanabhan says: “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.”
Once the current testing is completed, Cummins intends further evaluation of the hydrogen engine in on-highway and off-highway applications.
The hydrogen engines can use green hydrogen fuel, produced by Cummins-manufactured electrolysers – emitting near-zero CO2 and NOx emissions.
Cummins says the hydrogen engine has the potential to expand the technology options for sustainable transport – “complementing our capabilities in hydrogen fuel cell, battery electric and renewable natural gas powertrains.”
It offers OEMs and end-users the benefit “of continuing to use familiar mechanical drivelines, with vehicle and equipment integration mirroring that of current powertrains, while continuing to provide the power and capability for meeting application needs.”
Meantime, Cummins has signed an agreement with global industrial gases supplier Air Products, to supply hydrogen fuel cell electric powertrains to convert its fleet of around 2000 trucks to FCEVs – starting next year.
