The objectives of this study are to evaluate the technical and cost implications retrofitting post-combustion Carbon Capture Storage (CCS) in existing coal-fired power plants Thailand, with a special focus on Mae Moh plant managed by Electricity Generating Authority Thailand (EGAT). We undertake detailed analysis using AspenPlus simulation models determine optimum capture per ton CO2 examine effects various flue gas loads performance cost-effectiveness. research reveals key operational insight: as flow rate increases, decreases, indicating economies scale CCS operations. Furthermore, explores potential for integrating solar photovoltaic (PV) technology renewable energy source, which shows promise lowering Thailand’s sector emissions costs. By comparing levelized electricity (LCOE) PV against conventional generation considering country’s favorable geographic climatic conditions, emerges an economically viable environmentally sustainable alternative. findings aim inform strategic policy decisions advocating transition more systems emphasizing balance between environmental responsibility economic feasibility.
