Challenge
Climate change also requires action in the field of international aviation. While the technologies for environmentally friendly air transport are still quite challenging and synthetic fuels need to come onto the market, a lot is already happening on the ground, where considerable emissions are still being produced today.
Project scope
In the finalize! project, large utility vehicles at Stuttgart Airport are being tested with battery-electric drive systems. Electric utility vehicles are being procured for the airport apron and the associated charging structure is being installed. While the vehicles are in use, operating data will be collected and used to carry out a life cycle analysis and a comparison with alternative technologies. In addition, charging strategies for energy integration and support of the power grid will be developed and analyzed. The findings from the operating phase will then be used for the initiation of standardization processes for refuelling operations by electric vehicles and the development of a cross-vehicle charging infrastructure for airport vehicles.
