Cummins is working across the hydrogen sector

Engine could be cheaper to run than hydrogen fuel cells, especially for heavy vehicles

Engine manufacturer Cummins has started testing a hydrogen-fuelled internal combustion engine (HICEV). Most hydrogen vehicles in operation are electric vehicles powered by a hydrogen fuel cell. If Cummins were successful in commercialising the technology, then manufacturers would be able to offer low-carbon vehicles without having to radically redesign their models. Following the proof-of-concept testing, Cummins plans to evaluate the engine in a variety of road applications. Technological advancements have allowed the company to avoid the performance limitations usually associated with converting diesel or natural gas engines to run on hydrogen.  “We are using all new engine platforms equip
