Description
Carbon Capture and Utilization (CCU) is essential for mitigating climate change by re-purposing $CO_2$ emissions into sustainable fuels and chemicals. A pivotal step in this process is the conversion of $CO_2$ into carbon monoxide (CO), a precursor for syngas, methanol, and Fischer-Tropsch hydrocarbons. While traditional thermal and electrochemical methods often suffer from high costs, limited scalability, and the need for harsh operating conditions [1], plasma-based technologies offer a promising alternative. These systems can be driven by renewable energy and utilize electron-driven mechanisms to dissociate $CO_2$ at milder temperatures [2, 3]. In this study, we utilize a sub-atmospheric alternating current (AC) plasma system to investigate the electrical characteristics of pure $CO_2$ plasma. By analyzing current-voltage profiles and plasma power via Lissajous figures across varying pressures[4], we aim to determine the optimal power requirements for efficient $CO_2$ dissociation.
