The parcel transport by solar ship across the Spree River started in October of 2022. Since then, according to DHL, up to 350 shipments a day have been delivered in the capital via this CO2-neutral route. By way of comparison, the Group delivers around 250,000 parcels per day in Berlin. The parcels transported by the 10.50-meter-long, 2.50-meter-wide ship first arrive by road at the Börnicke parcel center northwest of Berlin. From there, an emission-free truck takes the deliveries to the southern port of Spandau, where they are loaded onto the ship. They then continue across the Spree to the Westhafen. From there, delivery staff on electric cargo bikes take the parcels to recipients in the immediate vicinity.
