The article discusses the pressing need for carbon dioxide (CO2) reduction to address global warming and the potential role of direct air capture (DAC) in achieving this goal. DAC, particularly through electrochemical methods, is highlighted for its flexibility and potential for integration with renewable energy sources. The captured CO2 can be converted into renewable methane (CH4), offering opportunities for energy distribution and carbon emission reduction. The article presents a novel hybrid electro-thermochemical device that combines DAC and H2 production with CO2 methanation, showcasing a cost-effective and efficient process. By integrating electrochemical and thermochemical modules, the device enables optimized CO2 release, H2 production, and methane generation, emphasizing energy efficiency and system cost reduction in the carbon capture and methane production processes.
