The scientific contribution of this work is to answer the questions how technically mature, energy-intensive, and expensive different Power-to-Fuel concepts are compared to each other. Forthis purpose, H$_{2}$-based production processes of eleven different standard-compliant transport fuels were techno-economically compared. The methodological focus is on the homogeneity of the calculations to ensure comparability as well as on the process engineering and design to be able to supply technically and scientifically sound recommendations. The simulation-based and therefore technically robust assessment was carried out using the process simulation software Aspen Plus$^{®}$. Thus, possibilities in terms of production technologies were revealed, and efficiencies as well as costs were determined. For the process engineering analyses, all required chemical plants have been designed in Aspen Plus$^{®}$, whereby technically established processes were adapted and missing sub-processes or synthesis routes were fully new developed. This includes, for instance, fully new process concepts for the H$_{2}$-based synthesis for higher alcohols. Subsequently, all sub-processes of promising synthesis routesbased on H$_{2}$ and CO$_{2}$ were simulated, evaluated, and compared techno-economically. The comparability of the simulations and calculations is ensured by the strict compliance of identical assumptions and boundary conditions. The simulation models were modularized, a validated physico-chemical model for the description of missing component systems was implemented in Aspen Plus$^{®}$ and all unit operations were designed in detail to determine the process utility demand. The heat integration of the sub-processes or synthesis routes is tied to common utilities of a chemical production location (Verbund site). The products largely meet today’s fuel standards. All designed process concepts have no by-products except water, since even non-recyclable by-products of the reactions are converted to synthesis gas using reformers, which can be recycled. Thus, the process concepts are suitable for large-scale use. The sensitivity of the results to the assumptions and boundary conditions was analyzed and assessed. With the holistic picture of Power-to-Fuel concepts and products, this work aims to provide a robust basis for integrating Power-to-Fuel concepts in simulations of future energy systems and energy supply strategies as well as for recommendations regarding the choice of transport fuels for a future at best CO$_{2}$-neutral mobility.
