Efforts to decarbonise heavy-duty and off-road machinery in Germany have gained significant momentum through the 'PoWer' project led by Purem by Eberspaecher. Supported by the Federal Ministry for Economic Affairs and Climate Protection, the initiative aims to investigate the potential of hydrogen engines in industries like construction and agriculture. Hydrogen engines are lauded for their efficiency and minimal untreated emissions, making them well-suited for non-road mobile machinery applications. The consortium involved in the project includes major industry players such as MAHLE, DEUTZ, and Claas, along with academic institutions like the Karlsruhe Institute of Technology and the German Aerospace Center. Their focus is on conducting vehicle concept studies and infrastructure evaluations to advance hydrogen engine technology for off-road applications. Purem by Eberspaecher is particularly investigating the impact of hydrogen on materials and developing exhaust gas aftertreatment systems to meet future emissions standards. The German government's significant financial support of €2.8bn for hydrogen decarbonisation projects and €24bn for the national hydrogen network aligns with the country's National Hydrogen Strategy objectives. These include targets like installing 10 gigawatts of domestic electrolysis capacity, establishing a hydrogen transport network exceeding 1,800 kilometers by 2028, and fostering domestic and international hydrogen projects with multi-billion euro allocations.
