We propose an energy–efficient carbon dioxide (CO2) capture system for Carbon Capture and Utilization (CCU). In our approach, CO2 reacts with hydrogen (H2) derived from renewable energy sources to produce methane. The gas mixture used in the reactor consists of CO2 and renewable–origin H2. When hydrogen is introduced into the CO2 desorption section of the separation process, the partial pressure of CO2 decreases, leading to an accelerated CO2 desorption. This acceleration significantly contributes to energy savings across various technologies, including absorption liquid, adsorbent, or membrane separation methods.
