Cummins to launch hydrogen internal combustion engine for off-road equipment
Recently, Cummins launched a B6.7H hydrogen internal combustion engine. The new hydrogen internal combustion engine has a power of up to 216kW and a torque output of 1200 N·m, and a series of innovative components have been developed for the working cycle of heavy-duty conditions. At the same time, the engine's peripheral equipment has also been fully upgraded to ensure that it can maintain excellent performance and stability in extreme environments.
Cummins France revealed that the company plans to gradually launch all derivatives of the B6.7 engine series in 2026-2027. This schedule is highly consistent with the upcoming Stage VI emission standards. Given that these engines share the same platform, customers will have the flexibility to choose the engine model that best suits their specific operating needs and site environment, thereby achieving a smooth transition from diesel power to hydrogen energy with only minor adjustments to the engine compartment.
At the recent INTERMAT 2024 exhibition, Cummins will also showcase its cutting-edge NProxx hydrogen fuel storage system. The system is designed to provide efficient fuel replenishment for mechanical equipment equipped with hydrogen internal combustion engines and fuel cells. Its storage tank uses 700bar high-pressure storage technology and can achieve smooth output at a pressure of 10bar. This storage system can be easily installed on remote sites, and can be easily removed and refilled when the fuel is exhausted, and then put back into use.
