Cummins tests hydrogen-fueled internal combustion engine
Cummins Inc. began testing a hydrogen-fueled internal combustion engine. The proof-of-concept test is building on Cummins’ existing technology leadership in gaseous-fuel applications and powertrain leadership to create new power solutions that help customers meet the energy and environmental needs of the future. Following this trial, the company plans to evaluate the engine in a variety of on- and off-highway applications, supporting their efforts to accelerate the decarbonization of commercial vehicles.
“Cummins is thrilled about the potential of the hydrogen engine to reduce emissions and provide power and performance for customers,” said 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.”
“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,” said Jonathon White, Vice-President of Engine Business Engineering.
Hydrogen engines offer OEMs and end-users the benefit of adaptability by 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.
The hydrogen engines can use green hydrogen fuel, produced by Cummins-manufactured electrolyzers, 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, electrolyzers 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.
