Engine manufacturer Cummins is testing a hydrogen-fuelled internal combustion engine, the company has announced. The proof-of-concept test is building on its existing know-how in gaseous-fuel applications and powertrains to create new 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,” commented Srikanth Padmanabhan, President of the Engine 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. 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 the company’s 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,” added 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 exhaust 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 utilising either Cummins fuel cell or engine power.
