Distinctive technological elements of numerical simulation for underground carbon dioxide storage

This lecture provides an overview of the advancements in carbon capture and storage（CCS） technology and its application to numerical simulations. According to the 2023 report by the Global CCS Institute, the number of carbon capture, utilization and storage（CCUS）projects has tripled in the past five years, and in Japan, several projects have advanced to the feasibility study stage. However, the study of CCS did not begin just recently; it has a history of about 30 years. This history can be divided into three phases: the initial rise, the period of stagnation, and the current phase. The technological advancements during each period were closely related to the technologies used in oil and natural gas development.
