The share of renewable energy sources in electricity generation is increasing day by day. However, being an intermittent resource, it is not enough to completely end the use of fossil fuels. In the current situation, the use of fossil fuels continues, but the amount of carbon they release into the air during combustion is at a point that cannot be ignored, and carbon capture, storage and transportation technologies gain importance at this stage. In this study, examples of Carbon Capture, Utilization, and Storage (CCUS) technologies used in the electricity generation sector in the world and in Türkiye are examined. The CCUS techniques used in the plants and the working principle of these techniques are mentioned. The efficiency of the plants before and after CCUS is analyzed according to the fuels used. The situation in Türkiye and the world is analyzed technically, economically and politically and the potentials are evaluated. According to the data obtained, it is seen that the use of amine-based carbon capture technology (monoethanolamine (MEA)) is more appropriate in the electricity generation sector. Carbon capture from flue gas after combustion has been found to slightly reduce the total system efficiency. As a result, in addition to the few examples in the world, the applications in Türkiye are at the pilot stage and it is seen that there is already a high potential for carbon capture when the installed natural gas and coal plants are considered.
