Within the project "Elektrischer Antriebsstrang für Arbeits- und Nutzfahrzeuge" (ELAAN), fuel cell and battery modules are combined with an electric motor to power a utility vehicle LADOG T1250 which is often used in municipal applications. Conventionally, the vehicle is powered by a four cylinder diesel engine which feeds a hydraulic pump. As fuel cells, batteries and electric motor replace the diesel engine and hydraulic traction system, the fuel economy can be improved by a factor of approximately three. Hydrogen is stored at 350 bar and can be refilled within few minutes. This makes the use of the electric vehicle comparable with the conventional one in terms of operation and refill time.
