Germany's 100% hydrogen engine passes test with increased power density

Germany-based Everllence has successfully commissioned and tested a single-cylinder 35/44DF engine running on 100% hydrogen at its Augsburg site, marking a significant advancement in hydrogen combustion technology. This development, part of the HydroPoLEn project funded by the German Federal Ministry for Economic Affairs and Energy, involved re-engineering engine architectures and designing combustion processes and mechanical components optimized specifically for hydrogen use. The new process notably increases power density during hydrogen operation, and the Augsburg site now features dedicated hydrogen supply infrastructure, positioning it as a hub for alternative fuel research. The HydroPoLEn consortium includes technical and industrial partners such as WTZ, the Technical University of Munich, Tenneco, and Carnival Maritime, reflecting a collaborative effort to address the challenges of hydrogen engine safety and component adaptation. Project leaders emphasize that while the technology is still in early market readiness stages, hydrogen is emerging as a viable option for decarbonizing passenger ships, complementing other fuels like ammonia and methanol in future
