This engine uses the US-based manufacturer’s ‘fuel-agnostic platform’, where below the head gasket each fuel type’s engine has largely similar components. The main differences take place above the head gasket for individual fuel types.

H2 View understands that the ‘zero-carbon’ hydrogen engine is intended to be produced in both the 15-litre and 6.7-litre model, which Cummins claims will ‘enable the industry to take action and reduce GHG emissions’.

Additional testing on Cummins’ more advanced prototypes is set to begin soon, with full scale production expected in 2027.

The testing of Cummins’ hydrogen internal combustion (ICE) technology began in July 2021, with the company stating that the ‘medium-duty engine’ has achieved over 810 ft-lbs of torque and 290hp in testing.

Srikanth Padmanabhan, President Engine Business at Cummins said, “Reducing well-to-wheels’ carbon emissions require innovation of both energy sources and power solutions.

“While use cases for battery electric and fuel cell electric powertrains are promising, the pairing of green hydrogen in the proven technology of internal combustion engines provides an important complement to future zero emissions solutions.”

Despite concerns over the efficiency of hydrogen ICEs, Jim Nebergall, General Manager Hydrogen Engines at Cummins, believes there is a place for them in the market.

Nebergall said, “Our customers are responding favourably to this practical technology. These engines look like engines, they sound like engines and fit where engines normally fit.”

The work of Cummins has been praised by Daryl Wilson, Executive Director at the Hydrogen Council who said, “Heavy-duty trucking is critical to the global economy and is one of the hard-to-abate sectors of the economy.

“We are encouraged by the progress at Cummins in the development of hydrogen-fuelled internal combustion engines and look forward to continued advancements that can help us reach cost-effective decarbonisation of economies worldwide.”

North American Hydrogen Summit  

H2 View is taking its events platform to America’s original clean hydrogen hub of California. Together with the California Fuel Cell Partnership (CaFCP), we will stage our North American Hydrogen Summit in San Francisco on July 14-15.

As our summit theme Building Bridges: Hydrogen hubs and investment suggests, the event will explore the $8bn of funding announced to create at least four regional hydrogen hubs in the US. These hubs will turbo-charge the nation’s progress toward heavy trucking and industrial sectors that run without producing carbon pollution – and they may just provide the path forward to a hydrogen-fuelled future.

With California and Texas vying to be America’s hydrogen capital today, where are the hubs of tomorrow? Further still, what can other states, and countries, learn from California’s success story? And how can we build bridges to a successful flow of international investment?

If you are a member of the CaFCP, be sure to grab your ticket at a discounted rate with a code that can be provided to you by the events team.
