Cummins Inc. has taken a step forward in advancing zero-carbon technology as the company begins testing a hydrogen-fueled internal combustion engine.
The proof-of-concept test aims to create new power solutions that help customers meet the energy and environmental needs of the future.
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 decarbonization of commercial vehicles.
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. 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.
Integrating hydrogen technology
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. 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.
