With to the hybrid power source, the buses, with a tank capacity of 38.2 kg of hydrogen on board, will be able to carry out a full day’s schedule of 350 km (217 miles).

Since electric buses in our public transport network do not offer the necessary range, we are pleased that with fuel cells we can use an environmentally friendly drive system in Wuppertal. As we also produce hydrogen with an environmentally friendly method, our project is a one-stop-shop.

Together with the lithium batteries and electric motors, the fuel cells form the basis of the all-electric power source. Hydrogen is converted to electricity in the fuel cell, with water vapour as its only emission, while the batteries provide additional power wherever and whenever needed. With this hybrid power source and the re-use of braking energy, around 8 kg of hydrogen are consumed over a distance of 100 km.

Ballard believes that its fuel cell engine product line has an unparalleled performance record. The company’s seven generations of FCveloCity fuel cell systems have been deployed in buses in 15 countries on 5 continents during the past 10 years. These fuel cell systems powered buses that have travelled more than 12 million kilometers (7.45 million miles) cumulatively in revenue service, equivalent to circling the globe 299 times.

In addition, Ballard believes that its FCveloCity products have demonstrated industry-leading durability, as evidenced by more than 25,000 hours of revenue service in buses of the Transport for London fuel cell bus.

The procurement of new vehicles fits into the framework of Germany’s national innovation program for hydrogen and fuel cell technology (NIP), and is financed by the German Federal Ministry of Transport and Digital Infrastructure (BMVI), financed by the “Fuel Cells and Hydrogen Joint Undertaking” (FCH JU), the European public-private partnership is aimed at accelerating the market introduction of fuel cells and hydrogen technology, operating under the EU Horizon 2020 program.

Van Hool has been building hydrogen buses for the American market since 2005 and for the European market since 2007. By now, Van Hool has produced 53 hydrogen buses for North America (21) and Europe (32). The eight hydrogen-powered tram-buses Van Hool is manufacturing for Pau (France) should be added to this total. These are to be delivered in the second half of 2019.
