Die rohstoffliche Nutzung von CO 2 gewinnt in Anbetracht des Klimaschutzes und als alternative Rohstoffbasis zunehmend an Bedeutung. Sowohl elektrochemische Direktsynthesen als auch thermochemische Verfahren zur CO 2 -Konversion gehen mit einem hohen Bedarf an elektrischer Energie einher. Ein Beitrag zum Klimaschutz ist nur im Fall einer CO 2 -armen Stromerzeugung möglich, wie sie z. B. durch die Nutzung von Windkraft oder Solarenergie realisiert werden kann. Vor diesem Hintergrund präsentiert der vorliegende Artikel eine Methodik zur Identifizierung von geeigneten Standorten für die CO 2 -basierte Produktion von Olefinen in Deutschland.Schlagwörter: Carbon capture and use, CO 2 -Nutzung, CO 2 -Quellen, Methanol-to-Olefins, StandortplanungThe use of CO 2 as raw material is increasingly gaining in importance as an option for climate protection and as an alternative raw material feedstock. Both direct electrochemical syntheses and thermochemical processes are associated with a high demand for electrical energy. A contribution to climate protection is only possible in the case of low-carbon power generation, as can be realized, e.g., by wind power or solar energy. This article presents a methodology for identifying suitable sites for the CO 2 -based production of olefins in Germany.

Accelerating CO2 electrochemical conversion towards industrial implementation

“…The employed substrates and targeted products must be economically deliverable to and away from the electrolyzer, respectively. Specifically, while some technoeconomic analyses have been performed, these focus mainly on the North-American market, underlying the need to develop analytic models based on topography for different regions of the world 31 . Such models would allow for more efficient collaborations between academia and industry, generating heat-maps of markets/locations with elevated CO 2 emissions, access to cheap renewable electricity and in addition close proximity to bio-mass sources.…”

“…for energy generation. As the CO 2 concentrations of such gases are rather low, the CO 2 has to be extracted prior to its utilization . State of the art is amine scrubbing, which, however, increases the energy demand for CCU .…”

Supply chain optimization for electricity-based jet fuel: The case study Germany

“…Regardless of the synthesis path, appropriate sites for large-scale synthesis of electricity-based fuels are limited. In a densely populated country with complex regulatory approval requirements, such as Germany, existing refinery sites seem particularly suited [22].…”
