A research team from Sungkyunkwan University in South Korea has developed the Gas Capture and Electricity Generator (GCEG), detailed in Energy & Environmental Science. This technology aims to power low-energy electronics and improve environmental outcomes by directly converting the energy from gas adsorption into electricity.
Current carbon capture systems require significant energy and are limited in pollutant handling. The GCEG features a dual structure with polyacrylamide hydrogels and carbon black-coated mulberry paper.
Testing showed it produced 0.8 volts and 55 microamperes with 50 ppm of nitrogen dioxide. When modules were interconnected, output reached nearly 4 volts and 150 microamperes, suitable for small devices. Further enhancements are needed for scalability.
