As the largest bus company in Austria, Postbus is driving innovative mobility solutions in Austria. In addition to the use of battery-powered electric buses, Postbus was the first company in Austria to test a hydrogen bus in regular service.
The technology is extremely promising: After all, hydrogen buses do not release any environmentally harmful emissions at all. And: Even the fuel cell that generates this energy is fully recyclable.
Hydrogen as a fuel for the electric motor
The bus is powered by an electric motor and refuelled with hydrogen. Inside the fuel cell installed in the vehicle, a chemical reaction takes place when oxygen is added, generating the energy needed to power the vehicle. A major difference to battery-operated buses is that electricity is generated directly inside the vehicle. The range of a hydrogen-powered bus is around 400 kilometres per tank of fuel. Hydrogen buses are therefore well-suited for intercity transport. The hydrogen bus offers a further advantage for winter operation: The chemical reaction in the fuel cell also generates heat, which can be used to warm the vehicle in winter.
