In order to examine the feasibility of Carbon Capture & Sequestration, a major technological strategy for the national goal of greenhouse gas reduction, this paper studies the various methods and corresponding costs for the transportation of $CO_2$ captured at the domestic thermal power plants, as well as performing comparative analysis with overseas CCS demonstration projects. It is predicted that the investment cost would be about 98 million USD when the using land-based pipelines to transport captured $CO_2$ from the thermal power plant located in the south coast. And using marine-based offshore pipelines, it will cost about twice the amount. When the captured $CO_2$ is transported from the power plant in the west coast instead, the cost is expected to increase substantially due to the transportation distance to the storage site being more than double to that of the south coast power plant case.

문제 정의
In addition to the above cost analysis, this paper analysed the major features of integrated CCS demonstration projects operating worldwide as well as performing cost analysis on transportation/storage aspects to analyse the geological and technological feasibility of domestic integrated CCS demonstration projects. Major overseas CCS project in 2016 as summarized by MIT [14] based on the latest report [15] published by GCCSI (Global CCS Institute) were analysed.
In relation to the CCS integrated demonstration project currently under review by the government, this paper analyses the cost of transportation of CO2 using pipelines (onshore and offshore piping), a major gas transportation system, using various domestic and overseas literature data.
제안 방법
As a main assumption for the analysis, the CO2 capture source was set as coal-fired power plants located on the west and south coasts of the Korean Peninsula in order to confirm the effect of distance to the storage.
Based on the above analysis of the various options for CO2 transportation, this study analysed the CO2 transportation cost from the capture source to the storage site for the method that was analysed as the most practically suitable option for large capacity CO2 transportation in Korea: pipeline transportation.
In order to examine the feasibility of Carbon Capture & Storage (CCS) for national GHG reduction goals, various technical options and costs for CO2 capture at domestic thermal power plants were calculated, and comparatively analysed with overseas CCS demonstration projects.
이론/모형
For the techno-economic evaluation of large scale CO2 transportation, overall scheme was designed using gCCS ver 1.1.0, PSE [16].
성능/효과
As a result of analysis using various literature values, it is predicted that the investment cost to transport CO2 to the East Sea Gas Field using onshore pipelines would be approximately 98 million USD (approximately 116 billion KRW) when the CO2 is captured from thermal power plants located in the south coast, which is geographically close to the East Sea Gas Field, and using offshore pipelines would increase the cost by about two times the amount.
Tables 2 and 3 below show the CO2 transportation costs for onshore + offshore piping and exclusively offshore piping for a coal-fired power plant located on the west coast (700 km from the storage site, based on offshore piping). As a result of the analysis, labor cost accounted for about 60% of the entire investment cost, followed by other expenses, material costs and land compensation, which make up the remaining portion. Operating expenses comprise of less than 1% of the total investment cost, being a minor portion of the investment costs.
From the analysis results, it was predicted that the investment cost would sum up to approximately 98 million USD (approximately 116 billion KRW) if the CO2 is transported from the candidate power plant located in the south coast (closest to the storage site) to the hub terminal through onshore pipelines, and then transported through offshore piping from the hub terminal to the storage site, while transportation with only offshore pipelines estimated to be approximately two times the amount (approximately 183 million USD, 220 billion KRW).
후속연구
Therefore, it will be necessary for future studies to quantify into cost data the various qualitative aspects related to CO2 transportation (civil complications, environmental pollution, difficulty of construction, etc.) to allow for quantitative comparisons as well as reliable cost analysis for onshore and offshore pipeline transportation technology.
Therefore, this study shows that further study on the selection of CO2 storage sites will be needed.
Therefore, when CO2 supply of the gas field is completed in the future, further study for the storage in nearby areas can be easily conducted.
