Strabag鈥檚 decarbonising construction project is being conducted at the Kanzelstein quarry in Gratkorn, Austria.
It is using a Liebherr L 566 H, said to be the world鈥檚 first large wheeled loader with a hydrogen engine.
Energie Steiermark is supplying green hydrogen for its own hydrogen filling station that has been built at the quarry.
The hydrogen-fuelled machine is expected to save 37,500 litres of diesel 鈥� or up to 100 tonnes of carbon dioxide 鈥� each year.
Strabag chief executive Klemens Haselsteiner said: 鈥淲e want to be climate neutral by 2040. The only way to achieve this is by consistently and comprehensively saving CO2, for example, in the operation of construction machinery.鈥�
The L 566 H from Liebherr is a prototype large wheeled loader 鈥� 24 to 27-tonne operating weight 鈥� with a hydrogen engine.
鈥淭he technology also enables large vehicles that are difficult to electrify due to their high energy demand to be operated without CO2,鈥� said Herbert Pfab, technical director of Liebherr-Werk Bischofshofen, the division of Liebherr that makes these machines. The hydrogen engines are manufactured at Liebherr鈥檚 engine plant in Bulle, Switzerland.
