Road freight transport is responsible for about one-third of road transport emissions and it is\nstill growing. One solution to decarbonize this sector are electric trolley trucks powered by overhead\nlines. We compare electric trolley trucks to conventional diesel vehicles from a techno-economic\nperspective in Germany up to 2030. We find that an infrastructure set-up ordered by utilization of\nroads can be financed up to 2700 km with higher savings than cost. The impact on the energy system\nis lower than expected and the largest impacts are found in rural areas with highway intersections.\nFurther fields of research are discussed.
