Japan Petroleum Exploration Co., Ltd. (JAPEX) has started feasibility studies for "Business Feasibility Study on Japanese Advanced CCS Project" in the fiscal year 2023 commissioned by Japan Organization for Metals and Energy Security (JOGMEC) in two areas: the Tomakomai area in Hokkaido and the Higashi-Niigata area. The former is a joint commission by Idemitsu Kosan Co., Ltd. and Hokkaido Electric Power Co., Inc., while the latter is a joint commission by MITSUBISHI GAS CHEMICAL COMPANY, INC., Tohoku Electric Power Co., Inc., Hokuetsu Corporation, and Nomura Research Institute, Ltd.
In both commissioned studies, each company is conducting specific studies on the CO₂ separation, capture, transportation, and storage, which constitute CCS projects. JAPEX is in charge of the studies related to the transportation and storage of CO₂. In each project, studies were conducted to select and evaluate candidate storage sites within the area, to start CO₂ storage by 2030. For site selection, a three-dimensional geological model based on various public data, seismic surveys, information obtained from existing wells, and various subsurface data owned by JAPEX were used to create reservoir models for storage simulations.
We will introduce the overview of these CCS projects and the studies related to CO₂ storage.
