, Ltd. , KKT, Kepple Group, and Ecrowd Inc. The round was part of a larger JPY 5. 93 billion series B funding.
Helical Fusion develops stationary fusion reactors using helical magnetic confinement of high-temperature plasmas using a pair of superconducting helical coils with a double-helix structure similar to DNA, for a sustainable source of power generation. The firm aims to provide a sustainable source of base energy by designing a fusion reactor with elemental technology. Helical Fusion plans revenue from selling fusion-generated electricity, licensing reactor technologies, and partnering with utilities and manufacturers once commercial fusion power plants become operational. The company plans to use the funding to accelerate fusion-energy technology development and demonstration, including Helix HARUKA and the development of its first power plant, Helix KANATA.
