The 39_CCU module includes the possibliity to use synthetic gas and liquids. Synthetic gases and liquids can be produced by the model if realization “on” is chosen. Synthetic gases and liquids refer to hydrocarbon liquid (e.g. petrol, diesel, kerosene) and gaseous fuels based on a synthesis of hydrogen and captured CO2. In case of gaseous fuels (h22ch4), it is the methanation process, while in the case of liquid fuels (MeOH) it is either a route via Fischer-Tropsch based on hydrogen or a liquid production route via methanol. A differentiation of the latter two technologies is not necessary due to similar technoeconomic characteristics. The resulting hydrocarbon fuels can then be used in all energy-demand sectors (transport,industry,buildings). The two synfuel technologies (h22ch4,MeOH) convert secondary energy hydrogen to secondary energy liquids or gases. The captured CO2 can either come from the energy supply technologies w/ capture, industry w/ capture and direct air capture. For the former two, it can have either fossil or biogenic origin.
