abstract = {Power-to-Fuel technologies are indispensable for achieving
a largely CO$_{2}$-neutral energy supply in the future. 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.},
