About
LINEA Innovations, Inc. (株式会社LINEAイノベーション) is a Tokyo-based fusion energy startup founded in September 2023, built on research from Nihon University and the University of Tsukuba. The company is developing an aneutronic fusion reactor using the 'FRC-mirror hybrid approach,' which combines field-reversed configuration plasma formation with mirror magnetic fields, and targets the hydrogen-boron (p-11B) fuel cycle. Because the p-11B reaction produces charged alpha particles instead of neutrons, it generates virtually no radioactive byproducts and requires no tritium, addressing key practical challenges around reactor material activation and regulatory compliance. Under its mission 'Fusion Energy to the Future Generations,' LINEA has been recognized by Falling Walls Venture as one of the TOP 100 Science Startups to Watch in 2026.
