El ferri fluvial Mondorf, cerca de Bonn, ya no lanza hollín negro al aire y, al navegar, solo se escuchan el viento y las olas. Desde febrero de 2025, motores eléctricos de 290 kW (400 CV) han reemplazado a los antiguos motores diésel. El Rin tiene aquí 400 metros de ancho. La travesía de este ferri para automóviles dura unos dos minutos. La energía proviene de una batería de 1000 kilovatios hora (kWh), lo que equivale a la capacidad de batería de 14 autos eléctricos.
