Toward the realization of a carbon-neutral society in 2050, it is necessary to actively work on the introduction and promotion of zero emission and negative emission technologies such as CO2 capture and storage (CCS) and the utilization of renewable energy to reduce CO2. It is also necessary to secure a storage site for CO2.
Regarding the storage site survey, the technical viewpoints of understanding the subsurface information such as the storage capacity of the target area and the social economic viewpoints such as the distance from the CO2 emission source are the important factors to be examined. The government and research institutes have been conducting continuous surveys of suitable storage sites in Japan and the surrounding sea areas. In addition, a wide range of fundamental technologies related to CCS development programs such as the Tomakomai CCS demonstration project has also been implemented by research institutes and private companies for recent years.
It is very important to confirm the CO2 storage capacity, injection rate and long-term stability of the storage system based on subsurface evaluation for investment decisions and appropriate operation management of CCS projects. In the near future, the government will establish standards for permitting CCS projects and making financial support decisions. When the evaluation process can be standardized, it will be possible to promote the efficient CCS business, and the JOGMEC's CCS guideline may indicate one direction toward standardization.
In this presentation, we will discuss a series of the subsurface evaluation workflow consisting of geological and geophysical data acquisition/processing/analysis, reservoir/seal evaluation, 3D geological model construction, storage capacity evaluation and CO2 injection simulation. In addition, we are going to organize the importance of each elemental technology and their issues to be solved in the future, and explain the relevance to ISO international standards.
