Site characterization and geotechnical aspects on geological storage of CO2 in Korea

Abstract

The long-term storage of carbon dioxide (CO2) in deep geological formations, known as geological CO2 storage (GCS), has the potential to reduce CO2 emissions by 20%, a figure considered necessary to stabilize atmospheric CO2 levels over the next century. The purpose of this paper is to present the current state and future direction of geological CO2 sequestration in Korea. This study reviewed current storage technologies and strategies related to GCS worldwide, and the most suitable basins for GCS in Korea were selected from current available geophysical and geological research results. Finally, scientific questions and technical challenges were discussed in relation to the injection, storage, and monitoring processes from geotechnical engineering perspectives.
