Systematic Framework for CO₂ Transport Design of CCS System in the Archipelagic State

In the carbon capture and storage system, carbon dioxide transport plays an essential role in connecting the source and sink points. A series of design stages should be developed to obtain a feasible transport design from an economic perspective. This paper presents a systematic framework for feasible CO₂ transport design. The framework combines various methods and procedures in an integrated manner. The framework consists of two stages. The first stage involves task and system boundary identification, design, and evaluation of the carbon capture and storage (CCS) network. Three design schemes with overall, regional, and pseudo-regional approaches are used to generate the CCS network. The second stage involves designing CO₂ transport in a CCS network with different transport technologies and evaluating all identified transport designs in terms of technical feasibility and economics. Two transport design scenarios are used in this stage, standalone design and shared facilities design. The framework is implemented for the CCS system candidate in the central and eastern parts of Indonesia. The specific cost is used to select the most effective transport designs. The results show that the framework is applicable for the CCS system with many sources and sinks separated in different regions. In such cases, offshore pipelines are not feasible to be applied because the CO₂ transport volume is relatively small and the high-pressure drop. The most effective transport design can be achieved by the regional scheme in which CO₂ transport is restricted only in the same regions.
