Cummins Inc says it has taken another step forward in advancing zero-carbon technology as the company began testing a hydrogen-powered internal combustion engine. According to him, the proof-of-concept test “builds on Cummins’ existing technological leadership in gaseous fuel applications and powertrain leadership to create new power solutions that help customers meet needs. energy and environmental issues of the future ”.

“Cummins is excited about the potential of the hydrogen engine to reduce emissions and provide power and performance to customers,” said Srikanth Padmanabhan, president of the engine segment. “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 the conversion of diesel or natural gas engines to hydrogen fuel. We have made significant technological advancements and will continue to move forward. We are optimistic about bringing this solution to market.

Following proof-of-concept testing, the company plans to evaluate the engine in various on- and off-road applications, supporting 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.

Hydrogen engines offer OEMs and end users the advantage of adaptability by continuing to use familiar mechanical drivelines with vehicle and equipment integration mirroring that of current powertrains while continuing to deliver power and performance. capacity required to meet application needs. Hydrogen engines can use green hydrogen, produced by electrolysers manufactured by Cummins, emitting near zero CO2 emissions through the tailpipe and near zero NOx levels. The planned investment in the production of renewable hydrogen on a global scale will provide a growing opportunity for the deployment of hydrogen fleets using either the Cummins fuel cell or engine power.

Cummins invests in a range of technologies to support hydrogen-based transportation, including hydrogen engines, fuel cells, electrolysers and storage tanks. “The high energy density of hydrogen allows for easily integrated on-board gas storage without compromising 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 into high pressure gas cylinder tanks and vehicle supply lines. NPROXX is also a leading supplier of containerized storage vessels, enabling rapid hydrogen refueling for end users.

Cummins says its “central role in expanding the hydrogen ecosphere” goes beyond fuel cells and storage solutions for the manufacture of carbon-free renewable hydrogen, with the experience of more than 600 electrolyser installations around the world. “The modular scalability of our electrolysers is ideal for a range of applications, from localized supply of truck and bus fleets to large-scale electrolysis. Cummins has unique hydrogen capabilities that span from fuel production to storage and vehicle power. ”
