This research aims to evaluate the technical and economic feasibility of implementing Carbon Capture, Utilization, and Storage (CCUS) technology as well as biomass co-firing systems at the Teluk Balikpapan 2×110 MW Steam Power Plant (PLTU). CO₂ capture simulations were performed using a post-combustion approach with amine solvents, comparing the efficiency between MEA/PZ and MDEA/PZ mixtures. The simulation results show that the MEA/PZ solvent achieved a CO₂ capture efficiency of up to 92.4%, with a lower regeneration energy requirement compared to MDEA/PZ. Co-firing with biomass (wood bark and palm kernel) affects the flue gas characteristics, increasing the energy consumption of the CO₂ capture system, but still results in a CO₂ purity of 99.2%. The economic analysis indicates that this CCS project is financially viable with an IRR of 10.02%, an LCOE of IDR 2,400.51 /kWh, and an investment payback period of 6.96 years. These findings confirm that integrating CCUS and biomass co-firing in an existing power plant can serve as a sustainable energy transition strategy to reduce carbon emissions in Indonesia.
