Mitsubishi invests in Commonwealth Fusion Systems
Massachusetts, 4 days ago
Mitsubishi Corporation (MC) is pleased to announce its participation in a third-party allotment of shares by Commonwealth Fusion Systems, a fusion energy start-up originating from Massachusetts Institute of Technology (MIT).
This investment was made in collaboration with a consortium of 12 Japanese companies.
In the field of fusion energy, this investment builds on MC’s previous investment in Kyoto Fusioneering, announced on May 17, 2023.
Fusion energy is produced when two light nuclei, typically deuterium and tritium, collide to form a single heavier nucleus, helium.
This is the same process that powers the Sun and other stars. Since no carbon dioxide is emitted during power generation and the fuel is abundantly available in seawater, fusion offers an almost inexhaustible energy source.
A small amount of fuel can produce a tremendous amount of energy.
Fusion is gaining global attention as a next-generation energy source that supports decarbonisation and ensures a stable energy supply.
In June 2025, the Japanese government revised its Fusion Energy Innovation Strategy, which outlines the development and promotion of fusion energy.
This policy aims to position Japan as a global leader in power generation by the 2030s.
CFS, a spin-off company of MIT, is the world’s leading and largest private fusion company, utilising the magnetic confinement system (tokamak type).
The company plans to build the world's first commercial fusion power plant "ARC" in Virginia in the US, with the intent of generating electricity in the early 2030s.
In June of this year, CFS announced that it signed a power purchase agreement with Google for 200 megawatts of electricity from its first ARC power plant.
The Japanese Consortium will acquire technical and commercial expertise in policy, regulatory, and the development, construction, operation, and maintenance of ARC from CFS's commercialisation projects in the US.
In addition, each consortium company will bring together its know-how and expertise and aspire to expedite the commercialisation and industrialisation of fusion energy power generation in Japan.
The collaboration between the Japanese Consortium and CFS is consistent with the Japan – U.S. joint partnership to accelerate the development and commercialisation of fusion energy power generation in Japan and the US, and represents a strong commitment and growing momentum toward the early realisation of commercialisation in both countries.
Through this investment, MC seeks to acquire cutting-edge knowledge in fusion energy and contribute to both decarbonisation and a stable energy supply by leveraging its extensive networks and industrial capabilities to support the practical application of fusion technologies. -OGN/TradeArabia News Service
