“…Figure 8 shows different concepts for power-to-fuel production from renewable hydrogen via electricity and carbon dioxide using different sources. Concept (a) considers the fermentation of bio-waste and biogas upgrading to bio-methane, including CO2 separation (see Decker et al [94]), in combination with renewable hydrogen. It is designed as an off-grid system for a power-to-fuel market launch scenario based on small-scale activity at farm sites.…”

“…Therefore, different research groups (see the literature listed above) have proposed various innovative separation technologies, such as reactive distillation [114], adsorption by zeolites [115], pervaporation [116], thin film [110], and falling film evaporators [109]. [94]), in combination with renewable hydrogen. Concept (b) foresees CO2 separation from air or from industrial sources in combination with hydrogen from water electrolysis using electricity from wind and solar energy within the framework of the German energy system in 2050 (see Stolten et al [95] and Robinius et al [96]).…”

Achieving the CO2 reduction targets for 2050 requires extensive measures being undertaken in all sectors. In contrast to energy generation, the transport sector has not yet been able to achieve a substantive reduction in CO2 emissions. Measures for the ever more pressing reduction in CO2 emissions from transportation include the increased use of electric vehicles powered by batteries or fuel cells. The use of fuel cells requires the production of hydrogen and the establishment of a corresponding hydrogen production system and associated infrastructure. Synthetic fuels made using carbon dioxide and sustainably-produced hydrogen can be used in the existing infrastructure and will reach the extant vehicle fleet in the medium term. All three options require a major expansion of the generation capacities for renewable electricity. Moreover, various options for road freight transport with light duty vehicles (LDVs) and heavy duty vehicles (HDVs) are analyzed and compared. In addition to efficiency throughout the entire value chain, well-to-wheel efficiency and also other aspects play an important role in this comparison. These include: (a) the possibility of large-scale energy storage in the sense of so-called ‘sector coupling’, which is offered only by hydrogen and synthetic energy sources; (b) the use of the existing fueling station infrastructure and the applicability of the new technology on the existing fleet; (c) fulfilling the power and range requirements of the long-distance road transport.

“…These fuels are considered as being produced mainly based on the electricity provided by VRES (Brynolf et al, 2018). Besides water electrolysis, this electricity also supplies processes like CO 2 hydrogenation (Pearson et al, 2012;Brynolf et al, 2018;Decker et al, 2019) or co-electrolysis of CO 2 and H 2 O (Larsson et al, 2015;Hänggi et al, 2019). Aside the two aforementioned keywords, the literature makes use of a scattered diversity of terms that aim at precising the features of the considered fuel: for instance, "solar fuel," "power gas" or "green synthetic fuel."…”

“…Due to the economic inertia and their infrastructure legacy (Ahlgren, 2012), fuels remain the most appropriate solution for sectors requiring high energy density (e.g. heavy-duty transport, shipping, aviation or chemical industry) (Zeman and Keith, 2008;Pearson et al, 2012;Rosa, 2017;Goede, 2018;Trieb et al, 2018;Decker et al, 2019;Albrecht and Nguyen, 2020;Stančin et al, 2020). Contino et al (2020) point out that the energy transition is an interdisciplinary effort and not solely about the power sector.…”

Utilization of the gas streams generated by the iron‐ and steel‐making industry for the synthesis of synthetic fuels or chemicals is a promising way to kickstart a technical carbon cycle. Methanol synthesis from cleaned blast furnace gas is a challenge for process design and operation due to high inert gas contents and fluctuations in the gas supply. In this work, a miniplant setup with an adiabatic quench bed reactor was operated with cleaned blast furnace gas over a wide range of process conditions. The experimental data obtained were used to validate a simulation model of the miniplant setup with the perspective for an optimization of the process operational parameters. A high agreement between experimental and simulation data could be obtained, validating the applicability of the simulation approach presented in this work.
