STRABAG and Liebherr have initiated a pioneering project at Kanzelstein Quarry in Gratkorn, Austria, to decarbonize the construction site. The project involves testing Liebherr's innovative L 566 H prototype wheel loader, which is powered by a hydrogen engine, making it the world's first large hydrogen wheel loader. The two-year trial, attended by key figures like Leonore Gewessler and Jan Liebherr, marked the beginning of this sustainability-focused initiative. Liebherr's hydrogen-powered wheel loader is set to undergo daily testing by STRABAG at the quarry. A hydrogen filling station is being constructed on-site, facilitated by Energie Steiermark to provide the necessary green hydrogen. This deployment aligns with Austria's climate goals, emphasizing the importance of green hydrogen in reducing CO2 emissions. The collaboration between Liebherr and STRABAG is not only a technological advancement but also a significant step towards decarbonizing challenging sectors like construction. The L 566 H prototype is expected to contribute to saving up to 100 tonnes of CO2 annually, equivalent to 37,500 liters of diesel. Liebherr's hydrogen engines, with their high efficiency and minimal emissions, offer a promising solution for the industry. The joint effort of two industry leaders showcases the potential of green hydrogen as a sustainable energy source for reducing greenhouse gases. The project's success could serve as a model for other construction companies looking to embrace climate-neutral technologies and drive decarbonization forward.
