CO2 use for the production of synthetic fuels:
Many sectors can directly use renewable energies through electrification. In aviation and heavy-duty transport, as well as in various other applications, will rely on liquid synthetic fuels in the future. Biomass-based fuels have been a possibility for some time, but their potential is limited (Biomass- to-Liquid).
Synthesis of hydrogen and CO2 captured from the air or industrial processes can produce syngas, which can be used to produce many different fuels (Power-to-Liquid). Direct production of synthesis gas from water and carbon dioxide using solar collectors (Sun-to-Liquid) is one possibility, but it is still under development.
