제목 | Current Status of CO2 Geological Storage Research |
초록 | According to the forecast of the International Energy Agency (IEA), carbon capture and storage (CCS) has the potential to reduce carbon dioxide emissions and could contribute to 19% of global carbon dioxide mitigation by 2050. Korean government recently announced that Korea has set its voluntary 2020 emissions reduction target to a 30 % reduction from its forecast under a "business as usual" scenario, which is equivalent to 4% less than the 594 million tons of carbon that was emitted in 2005. CCS is included to achieve this target. This presentation will introduce current status of CO2 geological storage programs worldwide. Four commercial CO2 storage projects will be first introduced which store more than 1 million tons of CO2 per year. Two demonstration projects of Otway in Australia and Nagaoka in Japan will also be explained. Research projects currently running in Korea are to be explained. Most of these projects are focused on the screening CO2 storage sites in both onshore and offshore sedimentary basins. Preliminary study shows that more than 1 billion tons of pore space will be available in the onshore basins to store CO2. The petrophysical properties of this storage sites will determine the actual storage capacity. Vast data of offshore basins are available including seismic data and drilling data. While onshore sedimentary basins seem to have unfavorable physical properties such as porosity and permeability, offshore sedimentary basins exhibit very good physical properties in sand thickness and porosity. We expect much higher storage capacity in offshore sedimentary basins. Laboratory experiments to determine the injectivity and storage efficiency will be finally explained including pilot study. The most urgent one in CCS program in Korea is to integrate the capture project and storage project. The business model integrating capture and storage projects will be briefly introduced. |
