press release

Fujikura Ltd. (Director, President and CEO: Naoki Okada) has announced its investment in Commonwealth Fusion Systems LLC ^*1 (hereinafter “CFS”), a U.S.-based fusion energy start-up company, in collaboration with a consortium of 12 Japanese companies^*2.
This marks our third investment in the fusion energy sector, following our previous investments in Kyoto Fusioneering and EX-Fusion which are both based in Japan.

[About CFS]
CFS is the world’s leading and largest private fusion company, utilizing the magnetic confinement system (tokamak type) ^*3 The company announced plans to build the world's first commercial fusion power plant "ARC" in Virginia in the United States, with the intent of commencing operations in the early 2030s.
The Japanese Consortium will acquire technical and commercial expertise in policy, regulatory, and the development, construction, operation, and maintenance of ARC from CFS's commercialization projects in the United States. In addition, each consortium will bring together its know-how and expertise and aspire to expedite the commercialization and industrialization of fusion energy power generation in Japan.   The collaboration between the Japanese Consortium and CFS is in line with the Japan – U.S. joint partnership to accelerate the development and commercialization of fusion energy power generation in Japan and the United States, and represents a strong commitment and growing momentum toward the early realization of commercialization in both countries. 

[About Fusion Energy]
Our high-temperature superconductors (HTS) achieve high current characteristics and strength even in high magnetic fields. This makes our HTS exceptionally suitable for use in high-temperature superconducting magnets, which are used to confine and control plasma at temperature of approximately 100 million degrees.
Since CFS’ founding, we have built a relationship with the company and have supplied HTS to CFS. Additionally, we are making further capital investments to increase HTS production for the social implementation of fusion energy reactors. We expect that our manufacturing technology will accelerate the development of fusion energy reactors and play an important role in realizing a carbon-neutral society.

[Purpose of investment]
Fujikura has built a relationship with CFS since its founding and has been supplying the company with high-temperature superconducting wire. Fujikura's high-temperature superconducting wire is capable of achieving high current characteristics and high strength even in high magnetic fields, and is therefore used in high-temperature superconducting magnets to confine and control plasma at approximately 100 million degrees.
Fujikura is currently investing in further increasing production of high-temperature superconducting wire in order to bring fusion energy reactors into practical use in society, and we expect that Fujikura's technological capabilities will accelerate the development of fusion energy reactors and play an important role in realizing a carbon-neutral society.

Fujikura will continue to innovate in order to achieve a sustainable energy supply that has a reduced environmental impact thereby contributing to societal development.
