Why do we need four different solutions?
"The mobility of the future is a major challenge. In addition to technical innovations and changes, we also need to change people's behaviour," says department head Brigitte Buchmann. "This is why all new forms of mobility are so important. In order to master the changeover, we have to develop various paths further and not rely on a single technology."
The current Motor Show is marked by new, standard electric vehicles. But these are no panacea for the mobility issues of the future. With the Hyundai Nexo and the Toyota Mirai, two hydrogen vehicles can also be seen at the Geneva Motor Show. Hydrogen is already very well suited for city buses, municipal vehicles or parcel delivery services. Fuel cell vehicles are emission-free locally and could significantly reduce air pollution in inner cities. However, the network of filling stations is currently still too thin for long-distance hydrogen traffic. This could soon change: The H2 Mobility Switzerland Association wants to establish a nationwide network of hydrogen filling stations in Switzerland by 2023. There are already 62 hydrogen filling stations in Germany. By the end of 2019 there should be more than 100.
E-Fuels for diesel and gasoline vehicles
But already today – and with the existing filling station network for diesel and petrol – it is possible to switch to renewable energies. The sustainably produced hydrogen must be further processed into gaseous or liquid fuels using an industrial chemical process (Fischer-Tropsch synthesis). Empa is realising and investigating such concepts in its mobility demonstrator "move" in Dübendorf and is testing the production and use of such fuels in reality.
