Evaluation of CCS Networks Based on Pinch Design Method in the Central Part of Indonesia

At least for two decades, various techniques have been developed to solve the greenhouse gas emissions problem. The carbon capture and storage (CCS) technology is the main solution to reduce carbon dioxide emissions from the industrial sector and power plant. CCS involves the capture of CO₂ emissions from an exhaust gas, transporting and storing in geological storage. All of these CCS activities give several planning problems related to geographical conditions that may be an archipelago country, a considerable distance between the CO₂ sources and sinks, and the difference in time of CO₂ capturing and injecting to storage. The process integration technique by pinch design method can be used for CCS networks. This paper presents an application of pinch design method for CCS networks in central parts of Indonesia. The integration of carbon incentive and carbon tax is proposed to evaluate the value of CCS networks. The effect of time difference between sources and sinks on the amount of CO₂ uncaptured was considered to assess the sensitivity of CCS project's value. The results showed that the combination of pinch design method with the carbon trading and carbon tax provided a potential method to assess the effectiveness of CCS networks.
