Scientists in South Korea have developed a new gas battery capable of turning greenhouse gases into electricity while capturing harmful emissions. The device, called the Gas Capture and Electricity Generator (GCEG), was created by researchers at Sungkyunkwan University in Seoul. Unlike traditional carbon capture systems that require large amounts of external energy, the new technology produces electricity directly during the gas capture process.
The research team, led by Ji-Soo Jang, designed the battery using carbon-based electrodes and hydrogel materials. When gases such as carbon dioxide and nitrogen oxides are absorbed, microscopic reactions inside the device generate a steady flow of direct current electricity without any outside power source. Researchers say the breakthrough could redefine greenhouse gases as a potential energy resource rather than simply pollutants.
Scientists believe the technology could support future self-powered environmental devices, including air-quality sensors and remote Internet of Things systems. Industrial facilities may also use the battery to reduce emissions while harvesting energy from exhaust gases. The study, published in the journal Energy & Environmental Science, highlights the system as a scalable and low-energy solution that could contribute to global carbon neutrality efforts.
