[HSC07-13] JOGMEC initiative for the transition toward a decarbonized society

Japan Organization for Metals and Energy Security (JOGMEC) is a governmental agency of Japan responsible for energy security in Japan. JOGMEC announced “JOGMEC Carbon Neutral Initiative” in November 2022, which is composed of three basic policies: 1) strengthening efforts for clean resources and energy, 2) strengthening efforts for decarbonized fuel and technology, 3) contributing to the development of systems necessary for decarbonization. This presentation will introduce our initiative for the transition toward a decarbonized society with highlighting the role of Carbon Capture and Storage (CCS).

We begin with our coverage of diverse clean energy developments that contribute to a stable energy supply in Japan. Then, we further discuss our role and responsibility for CCS projects in which a geoscientific understanding of the subsurface plays a crucial role. This is composed of the three aspects as detailed below.

First, we discuss the technical aspects of CCS projects with an emphasis on the subsurface technologies. We discuss subsurface characterization, modeling, and monitoring for CCS, using real field examples from our ongoing CCS/CCUS demonstration projects in Japan and other countries. We present several of our experiences as follows: 1) reservoir characterization and modeling efforts for the planning of CO2 injection at the Minami-Aga oil field, 2) feasibility study for monitoring of CO2 injection at the Hirai gas field, and 3) CO2 injection operation at an onshore reservoir in an oversea country. We show the importance of fit-for-purpose application of technologies on a specific site basis. Lessons learned from these demonstration projects will lead to further optimization of future implementation of tangible CCS projects.

Next, we touch upon non-technical aspects of CCS projects, e.g., regulatory framework, business environment, carbon credits and CO2 cross-border transport and storage. We published CCS guidelines and a CCS carbon credit handbook aiming to help society better understand CCS projects. By introducing these publications, we discuss non-technical aspects of CCS projects which are crucial for the commencement of tangible CCS projects.

Lastly, we conclude our presentation with the introduction of the seven selected CCS projects, namely the advanced CCS project. These projects plan to capture domestic CO2 emissions and their feasibility study has started since 2023.
