<p>A promising approach to minimizing the carbon footprint involves optimizing the operational performance of industrial and energy facilities while simultaneously deploying advanced carbon dioxide sequestration and utilization technologies. In this study, we analyze modern methods and technological solutions for decarbonization, particularly in the context of underground storage or injection of carbon dioxide for water-alternating-gas (WAG) enhanced oil recovery. The current and prospective carbon capture technologies are examined, with a comparative assessment of their technological features, advantages, and limitations. The study includes an analysis of production costs associated with CO₂ and flue gas capture and emission mitigation across various industrial sectors and energy facilities, including their economic efficiency, cost structure, energy consumption, and process-related expenditures.</p>
