Major activities

Building a balanced energy resource portfolio and developing a value chain business

Energy Business Unit I is focused on establishing a stable supply system to meet growing energy demand, while maintaining a well-balanced energy resource portfolio and further developing its energy value chain business spanning upstream to downstream.

Mitsui's core oil and natural gas assets for exploration, development and production are based in the Middle East, Southeast Asia, Oceania, North America, and Europe, and we maintain a portfolio that is balanced in terms of geography, products, development phases and partners. In U.S. we utilize Mitsui's comprehensive strengths to build a value chain that leverages our upstream business in such areas as chemicals, liquefaction facilities and other plants, and steel products for drilling and ships. We are also pursuing the development of AI solutions for sub-surface structure analysis based on deep learning technology, utilizing our knowledge and expertise accumulated in the upstream business.

To strengthen our downstream oil activities in Asia, where demand is expected to grow, we have moved our base of operations from Japan to Singapore, and conduct our global crude oil and petroleum product trading and marketing primarily through Mitsui & Co. Energy Trading Singapore Pte. Ltd. In coal distribution, we are focusing on the Asian market, along with imports of coal for domestic customers. In addition, we are working to establish a stable biofuel supply system for Japanese consumers using biofuels such as wood pellets, which are increasing in demand in line with trends in climate change initiatives. We are also participating in a woody biomass power generation business in Tomakomai and Shimokawa in Hokkaido. Furthermore, we contribute to stable nuclear power generation through our nuclear fuel cycle business and uranium trading activities. Our goal is to contribute to a stable supply of energy, and we will constantly endeavor to enhance our trading activities to meet diverse customer needs.

Statement about the Management of Radioactive Materials

A wholly owned subsidiary of Mitsui & Co. in the United States purchases and sells uranium concentrate. However, the scale of business is extremely limited in terms of value and quantities handled when seen in the context of Mitsui & Co.'s overall business operations. Furthermore, the materials are not physically relocated and do not leave the storage facility. The storage contractor to which the materials are entrusted has been licensed by the U.S. Nuclear Regulatory Commission (NRC) to handle radioactive materials and ensures that the employees in its storage facility comply stringently with NRC standards concerning the management of radioactive materials and the risk of exposure. The storage contractor also undergoes regular inspections by the NRC. On this basis, we believe that the risk that uranium concentrate owned by Mitsui & Co.'s subsidiary will damage the local environment or cause exposure is quite limited. All of the uranium concentrate handled is intended solely for peaceful, civilian purposes, such as power generation, and is compliant with all NRC regulation. Note that Mitsui & Co. and its subsidiary stringently ensure compliance with NRC management standards (including those for nuclear waste) in handling the materials, but no nuclear waste is handled whatsoever.
