The Future of Carbon Capture Technology: A Novel Moisture Powered Thin-Film Supercapacitor that Adsorbs Carbon Dioxide

Carbon capture and storage technology (CCS) has tremendous potential to enable the use of fossil fuels while reducing the emissions of CO₂ into the atmosphere, and, consequently, combating climate change. CCS faces several challenges such as energy consumption, cost, low practical applications and environmental friendliness. Herein, a novel thin-film moisture electricity generator (MEG) in the structure of a supercapacitor that absorbs carbon dioxide is proposed. The developed thin-film supercapacitor successfully demonstrated the capacity for supercapacitive swing adsorption of CO₂, while generating green energy from ambient humidity.
