Summary
While hybrid and electrified drivetrain systems have already proven their effectiveness in on-road applications, their use in mobile machinery - particularly in the construction and mining sectors - remains significantly limited. In this context, hydrogen-based fuel cell systems offer considerable potential, as they enable shorter refueling times, higher energy densities, and longer operating cycles compared to battery-electric drives. Additionally, their local zero-emission operation represents a clear advantage over internal combustion engines.
Despite these technological benefits, fuel cell systems have yet to gain widespread adoption in heavy-duty mobile applications. This is primarily due to the extremely demanding environmental and operational conditions, which lead to high requirements for system integration, reliability, and drivetrain robustness. As part of this work, a hydrogen-powered fuel cell demonstrator vehicle was developed and tested under realistic field conditions to demonstrate the technical feasibility of zero-emission drivetrains in the construction and mining sectors.
