About Helical Fusion Inc.

Helical Fusion is a startup aiming to commercialize fusion energy. It spun out in 2021 by leveraging research outcomes from the National Institute for Fusion Science (NIFS), an inter-university research institute corporation under the National Institutes of Natural Sciences. The company adopts the "helical system," a unique Japanese nuclear fusion reactor design, and is advancing the "Helix Program," which fulfills the rigorous requirements demanded of commercial power plants.

Business Progress and Future Outlook

Helical Fusion is steadily progressing toward practical application by demonstrating core technologies for nuclear fusion reactors, initiating the construction of its final demonstration device, "Helix HARUKA," and securing Japan's first fusion energy power purchase agreement. Fusion energy is a national policy domain highlighted by the government as a key investment target for growth strategies. E-Crowd NEXT aims to strongly support the social implementation of Japan's fusion energy industry by mobilizing capital from both the public and private sectors, as well as from individual investors.
