abstract = {There is an urgent need to reduce carbon dioxide emissions
from the burning of fossil fuels in the transport sector.
Through its focused efforts in technology research on water
electrolysis and in the technoeconomic evaluation of future
transport solutions in the period under review, IEK-3
succeeded in improving the technological maturity of
advanced water electrolysis and gaining ground-breaking
insights into process engineering for the production of
synthetic fuels from H$_{2}$ and CO$_{2}$. Water
electrolysis at temperatures of roughly 70 °C permits
highly dynamic operation with fast start-up and shut-down
procedures. Electrolyzers with polymer electrolyte membranes
or potassium hydroxide solution have reached a sufficient
degree of maturity to facilitate the construction of large
plants on the megawatt scale, with current and future R\&D
activities focusing on improving performance, increasing
lifetimes, and reducing investment and operating costs.
Rolling out large-scale plants for electrochemical H$_{2}$
production serves as a test for their integration in the
energy system. Steam electrolysis at temperatures of up to
approximately 800 °C permits the use of surplus
high-temperature heat produced in many industrial
processes.The maturity of electrolyzers based on solid oxide
cells depends on that of the relevant fuel cells and is now
sufficiently high to enable plants to be constructed on the
kilowatt scale. Current and future R\&D activities focus on
resolving issues related to material changes that reduce
performance and lifetime; other priorities include designing
a reversible system for electrolysis and fuel cell operation
and achieving application-relevant cost targets. The
targeted processing of hydrogen from renewable sources and
carbon dioxide from climate-neutral sources produces a
synthetic, liquid fuel that in its ideal form substitutes
today’s kerosene or diesel and at the same time burns
without harmful residues. Dimensioning tools and methods are
being used to design a synthesis reactor – comprising an
autothermal reformer, WGS reactor, and catalytic burner –
which will synthesize the two source gases, H$_{2}$ and
CO$_{2}$, into a synfuel with high selectivity and low
conversion losses.},
