Hereby, a special focus is set on the Power-to-Fuel concept for the production of electricity based synthetic fuels. The frame of the investigations is set by the transport sector in its entirety, for which pathways for the reduction of climate gases are elaborated under different development scenarios. This thesis yields a strategy for the deployment of synthetic fuels for the transition to a transport sector in compliance with climate protection goals, based on quantitative analyses. Foundation for all system analyses is the general development of the transport sector by means of vehicle market developments. Two scenarios were elaborated to describe the development of vehicle mileage and energy demand until 2050. These were used next to three literature scenarios to describe the general development of the transport sector and, in combination with the CO2 reduction goals, set the framework for the applied system optimization programs to determine fuel demands. In a subsequently developed optimization model, approaches for calculating the economic performance of fuel synthesis plants were additionally implemented. In this manner, a production infrastructure for supplying the synthetic fuel demand including concrete locations for the production plants was calculated and evaluated by means of different case studies. Furthermore, a production concept for producing synthetic fuels in an off-grid system was developed to show the economic viability of the implementation in a short- to mid-term scenario. All investigations and results are ultimately merged using the s-curve method yielding the outline of a fuel strategy for a transition to a sustainable transport sector. Depending on the used scenario, the demand for synthetic fuels is calculated to be between 55 and 980 PJ for the year 2050. The lower and upper boundaries of these results are respectively given by scenarios with strongly optimistic and pessimistic market penetration rates of electric vehicles. In the reference scenario a synthetic fuel demand of 220 PJ has been calculated for 2050, and it should be considered, that the demand for 2030 is within a very similar range. Based on a comparison with historic development data of the base chemical industry in Germany, possible developments of the production capacity of synthesis plants were derived and compared with the previously calculated fuel demands. This analysis leads to the conclusion, that the market driven development can meet production demand for the year 2050. However, the necessary production capacity to supply synthetic fuel demand in 2030 is not reached. This suggests constructing a plan for import of fuel deficiencies from advantageous production regions. The implementation of production capacities in Germany can however be attractive in the phase of market launch.
