Comparative assessment of CCS with other technologies mitigating climate change

AbstractThe purpose o f this report is to show the importance of CCS as a climate change mitigation technology by comparing it with other climate change mitigation technologies currently being developed. In order to objectively evaluate those technologies including CCS currently being researched and developed, the study conducted and compared these technologies in term of their potential in reducing GHG emissions at two set points in the future. The authors believe that the result of the study can be an effective way to promote public acceptance (PA) of CCS technology. The study was conducted with support from the ‘R&D project of CO2 Geological Storage Technology’ which is subsidized by Japan’s METI. In the result of evaluation, it shows that in order for the CCS technology to become practical, risks must be more clearly identified and the economic viability must be improved. Therefore, preparing frameworks and building social systems that support CCS technology would be inferred to become critical elements. These analysis results can be re-assessed when situations change for each subject technology whenever appropriate and will help make it possible to deal with changing reality in a flexible manner
