Fujikura's Strategic Move in Fusion Energy

Fujikura Ltd., headed by President and CEO Naoki Okada, has recently made a pivotal investment in Starlight Engine Corporation, a company focused on driving forward the FAST (Fusion by Advanced Superconducting Tokamak) project. This initiative is a public-private partnership that aims to demonstrate electricity generation through fusion energy in the 2030s, positioning it as a central player in the ongoing search for sustainable energy solutions.

About Starlight Engine Corporation

Founded in April 2025, Starlight Engine is a subsidiary of the globally recognized fusion energy startup, Kyoto Fusion Engineering Co., Ltd. The company is tasked with overseeing the entire FAST project, which encompasses a variety of crucial elements such as technology and business development, securing funding, site selection, and building supply chains to achieve commercially viable fusion plants.

Understanding Fusion Energy

Fusion energy, which mimics the natural processes occurring in the sun, involves the fusion of light atomic nuclei (specifically deuterium and tritium) into a heavier nucleus, helium. This reaction releases immense energy – a single gram of fuel can generate energy equivalent to burning eight tons of oil. Notably, the fuel used in this process can be extracted from seawater, and the methodology employed for power generation through fusion does not emit carbon dioxide (CO₂). Consequently, fusion energy is gaining traction as a significant solution to environmental issues like global warming, playing a vital role in achieving a carbon-neutral society.

Objectives of Fujikura’s Investment

Fujikura views its investment in Starlight Engine and the FAST project as a critical step toward the societal implementation of fusion energy. A key element in this venture is Fujikura’s high-temperature superconducting wires, which are essential for creating and controlling high-temperature superconducting magnets that confine plasma necessary for fusion reactions. With over three decades of expertise in high-temperature superconducting wire technology and a proven track record of supplying similar materials for fusion energy projects in Japan and overseas, Fujikura aims to contribute significantly to the advancement of the FAST initiative through this investment.

Commitment to Sustainable Energy

Fujikura remains dedicated to reducing environmental impacts and realizing sustainable energy supply through further innovation. As the company continues to expand its presence in fusion energy development, it aims to leverage its technological advancements in superconductivity.
