Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The continuous rise of CO<sub>2</sub> emissions is a major cause of global climate change. Carbon capture and storage (CCS) is widely seen as a practical technology for reducing CO<sub>2</sub> emissions. CCS mainly consists of capturing CO<sub>2</sub> from large emitting sources and its transportation to a sequestration site where it can be stored safely for a long period of time. The average CO<sub>2</sub> emission growth rate of Korea is 1.0% which is the second highest among the Organization for Economic Co‐operation and Development (OECD) countries. It becomes even more challenging when CO<sub>2</sub> is transported to an offshore storage since there is little experience with subsea pipelines for CO<sub>2</sub> transportation. In this study, a plausible transport and storage model scheme has been developed and then employed to study different offshore CO<sub>2</sub> transportation cases for South Korea as: CO<sub>2</sub> transport in liquid phase (Temperature= −20<sup>°</sup>C, Pressure= 6.50 MPa); CO<sub>2</sub> transport in liquid phase (Temperature= 5<sup>°</sup>C, Pressure= 9.30 MPa); CO<sub>2</sub> transport in supercritical phase (Temperature= 40<sup>°</sup>C, Pressure= 15.00 MPa). CO<sub>2</sub> storage capacity in sedimentary basins of Korea is evaluated between 19 and 27.2 Gt (giga‐ton) of CO<sub>2</sub>. Finally, this paper explores the costs associated with transport and geologic sequestration of CO<sub>2</sub>. Transport cost varies from 10.9 to 15.5 US$/tCO<sub>2</sub> while the storage cost ranges from 20.8 to 21.3 US$/tCO<sub>2</sub> depending on the specific scenario and depth at which CO<sub>2</sub> is stored. Sensitivity analysis showed a decrease in storage cost of 62.4% and 93.6% in 2030 and 2050 respectively for projected CO<sub>2</sub> volumes in Korea. © 2013 American Institute of Chemical Engineers Environ Prog, 33: 978–992, 2014</p> </abstract>
