In the long term, carbon dioxide capture and storage (CCS) technology that reduces greenhouse gases on a large scale is in the spotlight. In order to evaluate the stability and efficiency of the CCS project and to minimize the impact on the surrounding environment, an environmental management system and legislation covering the life-cycle CCS process is proposed. The biggest issue with underground storage is whether there is a risk due to the leakage of injected carbon dioxide. This is because when carbon dioxide leaks, not only the storage efficiency is lowered, but also the health of local residents and the surrounding ecosystem are adversely affected. Therefore, it is essential to grasp the behavior of injected carbon dioxide and to prevent leakage. In particular, in the case of land storage, the protection of potable groundwater resources is the most important. Therefore, in order to ensure that underground storage is safe and eco-friendly, it is necessary to monitor all stages from site selection to closure during and after injection, and establish national licensing/license regulations and environmental management regulations.
In Korea, CCS technology was also selected as a key fostering technology for low-carbon green growth in 2014. It has been revised and has established and promoted the basis for CCS technology development, which aims to commercialize CCS plants and secure international technological competitiveness by 2020.
However, compared to such research and development, environmental management guidelines and legal regulations for environmentally safe CCS projects are still insufficient, and solutions related to public communication in particular need to be discussed further.
In this study, the concept, importance, and international research status of CCS technology as a means of responding to climate change are briefly reviewed, and tentatively named 「Carbon Dioxide Storage etc. Act」 draft as a part of the Integrated Environmental Act is considered.
