Cummins Hydrogen Engine Programme to move ahead with medium and heavy-duty platforms  


Funding Award from UK Advanced Propulsion Centre Will Accelerate Development

Darlington, UK (23 Sept. 2021) – Cummins hydrogen-fuelled internal combustion engine (H2-ICE) programme is ready to move ahead with the development of a medium-duty 6.7-litre and a heavy-duty 15-litre engine. Based on next generation platforms, the new hydrogen engines will aim to achieve zero carbon emissions, enhanced power density and improved thermal efficiency.

The engine development work will be accelerated after receiving a £7.2 million funding award from the UK Government provided through the Advanced Propulsion Centre (APC), recognising the potential for H2-ICE to play a major role in decarbonising commercial trucks and construction equipment from 2025 onward.

Designated as the APC18 BRUNEL Project, the technical readiness work will expand on Cummins’ experience from its existing H2-ICE programme and recent proof-of-concept testing. Planned development of the 6.7-litre hydrogen engine will focus on medium-duty truck, bus, and construction applications, such as excavators and wheel loaders. A new 15-litre platform offers the potential to bring hydrogen gas-fuelled engine capability to long-haul trucks with up to 44-ton gross vehicle weight and other heavy-duty applications.

The APC estimates that the successful execution of the Cummins H2-ICE project could reduce more than 11 million tons of carbon emissions annually, equivalent to the emissions of 2.4 million cars in the UK.

UK Minister for Investment Lord Grimstone said: “The BRUNEL Project is carrying on Darlington’s long tradition of skilled engineering, which will continue to grow for many years to come. We are working to build back better and greener after the pandemic and government investment in this
