CO2 partial pressure in the desorber is lowered by the H2 supplied to the bottom of the desorber and the mass transfer of CO2 from a liquid phase (i.e., amine solution absorbing CO2) to a gas phase is accelerated, making the desorber temperature lower. The mixture of CO2 and H2 gases collected from the head of the desorber can be used as material for the CO2 reduction reaction. As illustrated in the figure, the process to fabricate petroleum-independent fuel or chemicals is made feasible by making use of H2 electrolyzed by renewables (e.g., solar energy) and CO2 included in exhaust gas from facilities such as power plants.
