CO2 REMOVAL AND FIXATION SOLAR HIGH-TEMPERATURE SYNGAS GENERATION FORFUEL SYNTHESIS

For the use of remote solar energy sources, the generation of liquid f uels is an interesting extension because an existing infrastructure fo r transportation and distribution is available. In this paper two proc esses for climate neutral methanol synthesis working with high tempera ture processes for syngas generation from CO2 and water are described. They offer a better efficiency for the use of solar energy compared t o alternative processes with higher electricity demand. The CO2 enrich ment from the atmosphere has a higher energy demand compared to the re covery from concentrated emissions, but the use of solar energy for th e enrichment process leads to the decision to use atmospheric CO2.
