Carbon Capture and Storage (CCS) is considered as one of the most practical approaches for the reduction of CO2 emission. If CCS is applied to low carbon power generation, its deployment will require the construction of CO2transport infrastructure on a massive scale. Because of its cost, estimated at many billions of dollars, decision makers who set the direction of the climate-change strategy must understand how to deploy the CCS infrastructure and when to extend it properly. 

 However, there is a dearth of data concerning CO2 transport and storage. First, reservoir uncertainty has made it difficult to determine how many CO2 sources can be connected to a reservoir. Second, it is hard to decide a transport method for locations and estimate its cost due to a lack of CO2 transport data. Third, it is not clear whether to extend current transport infrastructure or change transport method when CO2 emission rates and reduction objective increase with time. Because of those, it is necessary to provide analysis of CO2transport network based on various transport scenarios.

 In this presentation, authors present analysis of the CO2 transport network deployment with time using South Korean case. To overcome a dearth of data, the cost model and configuration method of transport are estimated from similar cases, such as natural gas transport. After making the cost model per distance, authors match CO2 source to reservoir and decide transport methods by the regular rules on reservoir scenarios. Lastly, CO2transport network with time is optimized for cost savings.
