The most advanced carbon capture technologies currently require large amounts of energy and they are expensive. Researchers in the UK have designed a supercapacitor that consists of two electrodes of positive and negative charge. They found that alternating from a negative to a positive voltage improved the supercapacitor’s ability to capture carbon. When the electrodes become charged, the negative plate draws in the CO2 gas, while ignoring other emissions, such as oxygen, nitrogen, and water. Using this method, the supercapacitor both captures carbon and stores energy. They have developed a technique to understand the mechanism at play inside the supercapacitor when CO2 is absorbed and released. According to the researchers understanding these mechanisms, the possible losses, and the routes of degradation are all essential before the supercapacitor can be scaled up…read more.
