The machine is powered by an internal combustion engine modified to run on hydrogen. This clean burning concept produces mostly water vapour from the tailpipe, ensuring low emissions. The CO2 emission profile of the machine from manufacturing to decommissioning are estimated to be around 70% lower than for a conventional machines.

The special H966 power unit was developed at the firm’s Liebherr Machines engine facility in Switzerland and is based on conventional technology adapted for the purpose. The port fuel injection (PFI) and direct injection (DI) systems are said to ensure efficient combustion. Series production of the Liebherr hydrogen-fuelled engines is scheduled to commence in 2025. The H966 engine features six cylinder and a four cylinder H964 unit is also in development. The machine has a 50tonne operating weight.
