Helical Fusion bags $15m for fusion energy development

This will support the company’s efforts to build a fusion plant.

Helical Fusion has secured $15m in funding through its Series A round, boosting its efforts to develop a steady-state net power fusion plant in the 2030s.

In a statement, the company said the latest funding brings total capital, including grants and loans, to $35m, accelerating the “Helix Program”, a roadmap toward achieving its 2030 goal.

Helical Fusion’s fusion reactor is based on the stellarator design, a magnetic confinement approach that enables inherently stable, continuous plasma operation.

“Our concept builds on nearly 70 years of worldwide research, particularly at the National Institute for Fusion Science (NIFS) in Japan, home to the Large Helical Device (LHD)—one of the world’s most advanced stellarator facilities,” the company said.

Investors in this Series A round include the various organisations and individuals, such as SBI Investment Co., Ltd, Keio Innovation Initiative, Inc., X&KSK I Investment Limited Partnership, and KDDI Green Partners Fund L.P.

Under the Helix Programme, Helical Fusion is developing Helix KANATA, which is a full-scale pilot plant designed for steady-state, net-electric fusion power. It is also working on Helix HARUKA, an intermediate device for component and system validation.

These aim for continuous operation, net electricity, and high maintainability.
