In a project that recently started at the Kanzelstein quarry in Gratkorn, Austrian construction company STRABAG is carrying out a two-year trial of German-Swiss construction machinery manufacturer Liebherr’s large hydrogen-powered wheel loader.

A hydrogen filling station is being built to refuel the wheel loader directly at the quarry. Energy supplier Energie Steiermark will supply hydrogen for the filling station.

The hydrogen engines are manufactured by the Liebherr components division’s engine plant in Bulle, Switzerland.

“The technology also enables large vehicles that are difficult to electrify due to their high energy demand to be operated without CO₂,” said Herbert Pfab, Technical Director of Liebherr-Werk Bischofshofen.
