Fuel cell bus fleet starts operating in Wuppertal


In Wuppertal, ten scheduled buses with fuel cells are scheduled to go into operation on Saturday, June 20, 2020. This is reported by the WSW Wuppertaler Stadtwerke GmbH. The hydrogen for their drive is generated in Wuppertal with electricity from waste incineration.

In the bus, electricity from the fuel cell is temporarily stored in a high-voltage lithium battery on the vehicle roof or directly drives the electric motors. The vehicle has an output of 210 kW. Recuperation can limit hydrogen consumption to around 9 kg / 100 km. With a tank filling of 38.5 kg corresponding to a range of around 350 km and a tank duration of less than ten minutes, the deployment plans do not have to be significantly changed compared to buses with a diesel engine.

The two-axle A330 from the Belgian manufacturer Van Hool is around 12 meters long, has 35 seats and 39 standing places, one for a wheelchair user and one for a stroller. The buses are barrier-free, have USB connections and WiFi.

A bus costs around 650,000 euros, almost three times as much as a conventional diesel bus. The total cost is 12 million euros. 6.5 million euros came from the European Union, the federal government, the state of North Rhine-Westphalia and the Rhein-Ruhr transport association.

With the production and use of hydrogen as a fuel, pollutant emissions in Wuppertal are to be significantly reduced. In the waste incineration plant on Korzert, hydrogen is obtained from water by electrolysis, the electricity required for this comes from waste incineration. The electrolysis capacity is around 400 kilograms of hydrogen a day.

If necessary, the system can be expanded. The hydrogen bus fleet is to be doubled to 20 vehicles in the coming year.
