The Liebherr plant in Bischofshofen, Austria recently demonstrated two new development’s from Liebherr: the world’s first large wheel loader with a hydrogen engine and the opening of the first hydrogen filling station in the region.
Both innovations were demonstrated at a trade event, where the hydrogen wheel loader was demonstrated for the first time in practical use.
At the same time as this world première, the first hydrogen filling station in the state of Salzburg was inaugurated, representing an important milestone in the use of hydrogen as a sustainable energy source.
“To make progress in hydrogen research, we need to have access to hydrogen. We built this filling station to further advance our goals for decarbonising construction machinery,” said Dr. Herbert Pfab, Chief Technical Officer of Liebherr Bischofshofen.
Prototype L 566 H
The L 566 H from Liebherr is the world’s first prototype large wheel loader with a hydrogen engine.
Following extensive studies, the new technology was identified as the optimal solution for operating large vehicles that are difficult to electrify without carbon dioxide emissions.
For smaller vehicles up to about 15 tons, battery-electric solutions are often suitable. However, the situation is different with larger machines with an operating weight of up to 40 tons and high energy requirements.
Hydrogen reciprocating piston engines prove to be ideal in this case.

These hydrogen engines are manufactured at the engine plant of Liebherr’s Components product segment in Bulle, Switzerland. They enable not only zero emissions of greenhouse gases and almost no nitrogen oxides but are also highly efficient. Another advantage is the interfaces are comparable to those of a diesel engine, both thermally and mechanically. This represents a significant step forward in the development of sustainable large-scale machinery.
Another highlight of the event was a MAN truck, also powered by a hydrogen engine. This shows that hydrogen technology is not only feasible in wheel loaders but is already used in construction site trucks.
First hydrogen filling station
As part of the development of the hydrogen wheel loader, Liebherr Bischofshofen opened its own hydrogen filling station – the first of its kind in the state of Salzburg, Austria.
An important strategic partner in this project is Maximator Hydrogen, which is not only the manufacturer of the newly opened filling station, but also a research partner of Liebherr. Together, they are working on mobile filling facilities so machinery can be refuelled directly at the construction sites. This is important for remote construction sites and machines that are not very mobile.
MPREIS is also a partner for the filling station by ensuring the supply of green hydrogen.
