Empa is in the midst of establishing the Future Mobility Demonstrator on ist Dübendorf campus. This ambitious Projekt should reveal how excess electricity, generated by solar and wind-power, can be converted to fuel in the most sensible way. After all, this could slash Switzerland's carbon dioxide emissions by over 4 million tons – which would match perfectly the Swiss contribution to the Kyoto protocol. Empa will evaluate methods to fuel electric vehicles, hydrogen powered vehicles as well as natural gas cars.
