Abstract

The increase in greenhouse gases due to the combustion of fossil fuels is one of the major drivers of global warming and consequently drives the development of low-carbon technologies such as Carbon Capture and Storage (CCS). The aim of this study is to evaluate the technical and economical feasibility of the implementation of CCS technology in the Punagaya Subcritical Coal-Fired Power Plant (CFPP) 2×100 MW as a part of the energy transition strategy towards Net Zero Emissions (NZE) 2060. The simulation was carried out using Aspen HYSYS software, including coal combustion, CO₂ capture through MDEA-PZ solvent, dehydration, transportation, and storage of CO₂ in two saline aquifer locations in Sulawesi. Simulation outcomes indicate 9.7% of energy penalty and the CO₂ emissions reduction from 159 tons/hour to 2 tons/hour. The Levelized Cost of Electricity (LCOE) for the non-CCS power plant is 0.059 USD/kWh, whereas that with CCS increases to 0.161 USD/kWh. The self-consumption energy in the non�CCS CFPP is 22 GWh/year, whereas in the CFPP with CCS is 161 GWh/year. The net electricity production of the CFPP-CCS is a total of 1,501 GWh/year with a CO₂ avoided cost of 123 USD/ton CO₂. Economically, CCS application is still extremely expensive in Indonesia; carbon capture prices still require carbon tax adjustments in order to position CCS technology to be more competitive than other renewable energy sources.
