Construction and mining equipment leader Liebherr has unveiled its hydrogen-powered wheel loader, claiming it to be the first of its kind globally. The company has announced a pilot project at the Kanzelstein quarry in Gratkorn, Austria, marking a significant step in the use of hydrogen technology in heavy machinery.
The new project, initiated in collaboration with STRABAG, Austria’s largest construction company, aims to serve as a proof of concept over a two-year testing period. STRABAG will utilize the L 566 H wheel loader prototype, which was first showcased earlier this year at Liebherr’s private testing facility. This collaboration highlights the commitment of both companies to explore sustainable alternatives in construction operations.
Unlike traditional hydrogen fuel-cell systems, the Liebherr wheel loader is powered by a specially modified combustion engine that burns hydrogen instead of diesel fuel. This innovative design is expected to prevent the emission of up to 100 metric tons of carbon dioxide annually, which is equivalent to the carbon footprint of approximately 37,500 liters of diesel. This advancement underscores the potential of hydrogen technology to reduce greenhouse gas emissions in heavy machinery.
Dr.-Ing. Herbert Pfab, technical director of Liebherr, emphasized the significance of this technology, stating, “The technology … enables large vehicles that are difficult to electrify due to their high energy demand to be operated without emitting carbon dioxide.” This capability positions hydrogen combustion engines as a viable solution for sectors where electrification is challenging.
To support the operation of the wheel loader, a hydrogen filling station will be established at the quarry, supplied by Energie Steiermark. This station will provide the necessary green hydrogen for refueling, ensuring that the project aligns with sustainability goals and reduces reliance on fossil fuels.
