In addition to its fuel agnostic approach, Cummins will showcase a particularly interesting hydrogen ICE medium-duty concept truck at IAA 2022. The vehicle is powered by the B6.7H hydrogen engine developed by the Columbus-based company. The proof-of-concept installation is rated 290 hp (216 kW) and features a 700-bar pressure high-capacity hydrogen storage system. The H2-ICE conversion highlights the opportunity for truck applications across the 10-to-26T gross vehicle weight (GVW) range to operate on zero-carbon hydrogen fuel with a potential operating range of up to 500-kilometres.
The Cummins H2-ICE project utilised a Mercedes-Benz Atego 4×2 truck, representing a versatile and widely used vehicle for multi-drop distribution haulage. The hydrogen conversion work does not compromise truck performance, cargo capacity or payload. The seamless substitution of the diesel engine with the 6.7-litre hydrogen engine and integration with the existing driveline highlights the ability of H2-ICE to offer a zero-carbon solution for fleets based on a lower cost and a more easily deployable technology path.
Cummins hydrogen ICE truck: technical development
Technical development work on the H2-ICE concept truck was undertaken by the Cummins team at the Gross-Gerau facility in Germany, working in collaboration with vehicle engineering specialists, the EDAG Group. “The H2-ICE concept truck on show at IAA puts Cummins at the forefront of this rapidly emerging internal combustion engine technology using zero-carbon hydrogen fuel”, commented Alison Trueblood, Cummins Executive Director – On-highway Business Europe. “While Cummins hydrogen fuel cells offer a highly effective solution for specific applications within the truck industry, our hydrogen engines can also help accelerate fleet decarbonisation by offering a lower cost basis using more familiar engine technology”.
The B6.7H hydrogen engine with 1200 Nm peak torque is an all-new engine platform featuring cutting-edge technology to enhance power density, reduce friction losses and improve thermal efficiency. As a result, performance is equivalent to that of a similar displacement diesel engine and compatible with the same transmissions, drivelines and cooling packages.
