AB  - Carbon capture and storage (CCS) technology mitigates greenhouse gas (GHG) emissions. However, comprehensive studies assessing the sustainability of coal-based power generation (CBPG) with CCS remain limited. This study focuses on developing comparative sustainability indicators across the entire life cycle of CBPG integrated with CCS technology. Sixty-six pathways were analyzed after establishing five sustainability indicators for each. These indicators were standardized per megawatt-hour (MWh) of energy, encompassing quantitative impacts on water, land, air quality, and the levelized cost of electricity (LCOE). Among the pathways examined, the highest sustainability indicators were recorded for LCOE (118.05 USD/MWh), GHG emissions (374 kg of CO2 eq./MWh), and land use (0.513 m2/MWh). These were associated with a life cycle involving underground coal mining, subcritical power generation technology with dry cooling, and pre-combustion CCS technology. Conversely, the lowest LCOE (65.17 USD/MWh) and land use (0.337 m2/MWh) indicators were observed in a life cycle scenario involving surface coal mining, ultra-supercritical technology with a cooling tower, and oxyfuel CCS technology. This study presents sustainable scenarios encompassing the most cost-effective approaches, minimal use of natural resources, and the most minor GHG emissions. These scenarios cover an electricity demand range from 250 MW to 5000 MW.
