Humankind has relied on fossil fuels, such as coal, oil, and natural gas, but aside from coal, their reserves are expected to be depleted in just decades. To sustain our society, renewable energy is crucial. Although some renewable energy power generation methods are affected by weather conditions,  the geothermal development and power generation business, in which Mitsubishi Materials has been involved for more than 40 years, has gained attention as a stable power source that is not affected by weather fluctuations, as it utilizes the heat of underground magma.
To leverage our accumulated expertise in geothermal developments and operations of power generation and expand our business, Mitsubishi Materials is going to develop new geothermal areas once every three years. We currently have ongoing geothermal development projects in numerous areas. We started a geothermal resource survey in the Komonomori area of Akita Prefecture in 2021 and have participated in a geothermal development project in the Esan area, the southern part of Hokkaido Prefecture, since 2022. We are also making progress in the constructions at the Appi Geothermal Power Plant, which are scheduled to start operations in 2024.

Mitsubishi Materials had developed renewable energy power to provide electricity for our mines and smelters, which are now closed. To accelerate this movement, we have set a goal to expand renewable energy power generation to achieve 100% self-sufficient renewable energy by FY2031. In the future, we will enter into wind power generation, which is expected to have less power generation costs, and develop new biogas plants to expand the business areas. Through these initiatives, we will aim to achieve self-sufficient renewable power generation that can offset our company’s electricity consumption by FY2051.
What can we do “For People, Society and the Earth”? As Mitsubishi Materials has contributed to society by recycling and reusing resources and materials and generating sustainable energy, we will draw on our expertise and strengths to achieve carbon neutrality.
