Cummins and Accelera Showcase Broadest Portfolio of Decarbonizing Technologies With an Emphasis on Hydrogen - Seite 2

X15H Peterbilt Model 579 Concept Truck

Cummins will reveal a heavy-duty concept truck featuring the X15H hydrogen internal combustion engine (H2-ICE). The proof-of-concept installation with ratings up to 500 horsepower (372 kW) features a 700-bar pressure 80 kg high-capacity hydrogen storage system. The H2-ICE conversion highlights the opportunity for heavy-duty truck applications to operate on zero-carbon hydrogen fuel with an operating range of more than 500 miles. The hydrogen conversion work is not expected to compromise truck performance, cargo capacity or payload. The substitution of the diesel engine with the 15-liter hydrogen engine and integration with the existing driveline highlights the ability of H2-ICE to offer a zero-carbon solution for fleets to deploy quickly with limited investment.

Technical development work on the H2-ICE concept truck was undertaken by the Cummins team at the Cummins Machine Integration Center at its headquarters in Columbus, Indiana.

The X15H hydrogen engine with up to 1900 foot-pounds 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. A further benefit of the X15H is significantly quieter running than a diesel.

“Our hydrogen engines also can help accelerate fleet decarbonization by offering familiar engine technology at a lower cost,” said Jim Nebergall, General Manager of Hydrogen Engines.

Hydrogen Fuel Cell Engine

Hydrogen fuel cell engines turn hydrogen stored onboard a fuel cell electric vehicle (FCEV) into electricity to power the electric powertrain. This creates efficient, zero-emissions power for demanding applications with longer ranges and harder duty cycles. On display at ACT Expo is Accelera’s FCE150 Gen 4 fuel cell engine, powered to go the distance with superior performance and reliability and zero tailpipe emissions. It features increased power density, efficiency and durability with ease of system integration. It is available in 150 kW and 300 kW configurations with the flexibility to decarbonize a range of heavy-duty applications.
