For the use of remote solar energy sources, the generation of liquid fuels is an interesting extension because an existing infrastructure for transportation and distribution is available. In this paper two processes for climate neutral methanol synthesis working with high temperature processes for syngas generation from CO2 and water are described. They offer a better efficiency for the use of solar energy compared to alternative processes with higher electricity demand. The CO2 enrichment from the atmosphere has a higher energy demand compared to the recovery from concentrated emissions, but the use of solar energy for the enrichment process leads to the decision to use atmospheric CO2.
