Mitsui Concludes Memorandum of Understanding with Chugoku Electric Power on the Creation of a CCS Value Chain between Malaysia and Japan

Feb. 19, 2024

Mitsui & Co., Ltd. (Head Office: Tokyo, President and CEO: Kenichi Hori, "Mitsui") today concluded a memorandum of understanding with The Chugoku Electric Power Co., Inc. (Head Office: Hiroshima City, Hiroshima Prefecture, President and CEO: Kengo Nakagawa, "Chugoku Electric Power") concerning a joint study aimed at the creation of a value chain encompassing carbon capture and storage (CCS) and carbon transportation. This value chain will be developed for a CO2 storage site in offshore Malaysia that is being jointly developed by Mitsui, Malaysia's Petroliam Nasional Berhad through its subsidiary PETRONAS CCS Solutions Sdn Bhd ("Petronas"), and global multi-energy company TotalEnergies.

The study will cover the following topics, aiming to build a CCS value chain on a commercial scale between Malaysia and Japan:

  • The separation, capture, liquefaction, and temporary storage of CO2 emitted by a coal-fired thermal power plant operated by Chugoku Electric Power
  • Transportation of liquefied CO2 to Malaysia
  • Permanent geological storage of the CO2 in offshore Malaysia
  • Innovative initiatives, including the use of floating offshore temporary storage facilities

Mitsui, Petronas, and TotalEnergies have been jointly developing the CO2 storage site in offshore Malaysia since June 2023, and are aiming to start storing CO2 by around 2030.

By leveraging its knowledge of energy value chain development, including energy resource development, as well as its extensive business networks, Mitsui has been actively pursuing various initiatives with the goal of the early launch of CCS business. These initiatives include equity investment in UK CCS company Storegga Limited, and contracted survey services relating to a feasibility survey on Japanese Advanced CCS Projects promoted by the Japan Organization for Metals and Energy Security (JOGMEC) in 2023. Mitsui will continue to contribute to the creation of an eco-friendly society by providing CO2 reduction solutions through the global development of CCS business.
