Cummins began testing a hydrogen-fueled internal combustion engine.The proof-of-concept test is building on Cummins’ existing technology in gaseous-fuel applications and powertrain to create new a power solution.

“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,” said Srikanth Padmanabhan, president of Cummins’ engine segment, in a press release.

Padmanabhan says the company is “optimistic” about bringing the engine to market. Following the proof-of-concept testing, the company plans to evaluate the engine in a variety of on- and off-highway applications.

The effort supports the company’s efforts to accelerate the decarbonization 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,” said Jonathon White, vice president of engine business engineering.

Cummins is investing across a range of technologies to support hydrogen-based transportation including hydrogen engines, fuel cells, electrolyzers and storage tanks, Cummins officials said.
