Cummins has started testing an internal combustion engine powered by hydrogen. The proof-of-concept test leverages existing Cummins technology in gaseous fuel and powertrain applications to create a new fuel solution.

“We use all new engine platforms equipped with the latest technology to improve power density, reduce friction and improve thermal efficiency, which allows us to avoid typical performance limitations and efficiency tradeoffs. associated with converting diesel or natural gas engines to hydrogen fuel, ”said Srikanth Padmanabhan, Cummins Engine Segment President, in a press release.

Padmanabhan said the company was “optimistic” about bringing the engine to market. Following proof of concept testing, the company plans to evaluate the engine in various on and off road applications.

The effort supports the company’s efforts to accelerate the decarbonization of commercial vehicles.

“The hydrogen engine program has the potential to expand the technological options available to achieve a more sustainable transportation sector, by supplementing our capabilities in hydrogen fuel cell, battery electric and renewable natural gas powertrains,” said said Jonathon White, vice president of commercial engine engineering.

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