Development of CO2 Hub-Clustering Management in The South Sumatera Basin

Abstract

The escalating urgency of mitigating climate change demands immediate and effective strategies, with Carbon Capture and Storage (CCS) emerging as a pivotal solution. This scientific study presents a systematic and quantitative approach to the selection of carbon dioxide (CO₂) storage sites, focusing on the petrochemical industry in South Sumatera as the CO₂ source with annual emission reach 3.5 MtCO₂. A comprehensive screening process was executed, employing 14 distinct criteria, each assigned a weighted score, to ensure the inclusion of technically feasible options for CO₂ capture and storage. Notably, the emphasis on Subsurface Data Analysis, encompassing vital factors such as storage reservoirs, boundary zones, traps, potential injectivity, prospective storage resources, and existing seismic data, served as a cornerstone in enhancing the robustness of our assessments. The research successfully identifies 15 CO₂ storage fields, with the total storage capacity of up to 475 MtCO₂. This quantitative evidence underscores the substantial potential for large-scale CO₂ storage within the study area. Furthermore, the consideration of spatial dynamics, with two distinct scenarios within 100 km and 200 km radius from CO₂ emission sources, provided precise quantitative insights into the geographical distribution of these storage sites relative to emission sources. Importantly, the optimization of pipeline infrastructure and the utilization of existing Right of Ways (ROW) were quantitatively validated as cost-effective measures for CO₂ distribution, a crucial factor given the urgency of implementing CCS. Spatial calculations supported the proposal of a 600-kilometer pipeline route, demonstrating the quantitative feasibility of leveraging existing infrastructure to facilitate extensive CO₂ management. This research could help understanding large-scale CO₂ storage potential and provides valuable insights for CCS policy and business development in South Sumatera
