Helical Fusion Company Profile

Background

Helical Fusion Co., Ltd., established on October 22, 2021, is a Tokyo-based startup dedicated to advancing nuclear fusion technology. The company's mission is to develop and implement the world's first steady-state fusion reactor, aiming to provide a sustainable and stable energy source that will enable the coexistence of humans and the Earth for the next millions of years. By leveraging decades of research from Japan's National Institute for Fusion Science (NIFS), Helical Fusion seeks to transform Japan from an energy importer to a self-sufficient energy producer and exporter, thereby enhancing national energy security.

Key Strategic Focus

Helical Fusion's strategic focus centers on the development of a helical fusion reactor utilizing the heliotron design, a type of stellarator that employs continuously wound helical coils to create a stable magnetic field for plasma confinement. This approach is chosen for its potential to achieve steady-state, long-pulse operations without the need for plasma current, thereby reducing the risk of disruptions. The company is actively developing high-temperature superconducting (HTS) magnets and liquid metal blankets, essential components for efficient and compact fusion reactors. Targeting a pilot reactor with a generation capacity of 50-100 megawatts by 2034, Helical Fusion aims to commence commercial operations in the 2040s.

Financials and Funding

Helical Fusion has secured significant funding to support its ambitious projects:

Pre-Seed Round (May 2022): Raised ¥65 million (approximately $500,000) from investors including Makoto Naruke, former president of Microsoft Japan; Hideto Fujino, chairman and president of Leos Capital Works; Kazunori Asada, PhD; Sony Innovation Fund; Plug and Play Japan, Inc.; and BIOTOPE.

Seed Round (April 2023): Secured $6 million led by SBI Investment Co., Ltd., with participation from Mitsui Kinzoku. The funds are allocated for the development of the helical fusion reactor and related technologies such as HTS magnets and liquid blankets.

Japanese SBIR Grant (October 2023): Awarded ¥2 billion (approximately $13.5 million) by the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT) under the Small Business Innovation Research (SBIR) program. This grant is designated for advancing HTS cable technology, specifically the Wind and Impregnated Stacked Elastic (WISE) conductor, aiming to elevate its Technology Readiness Level from 5 to 7.

Pipeline Development

Helical Fusion's development roadmap includes:

HTS Cable Development: In February 2024, the company successfully conducted a critical test involving a 19kA current in its proprietary HTS cable, demonstrating superior superconductivity at cryogenic temperatures within a high magnetic field environment. This milestone is pivotal for the development of compact and efficient fusion reactors.

Prototype Reactor: Plans to construct and operate a prototype device integrating key technologies such as HTS magnets and liquid metal blankets. This phase aims to validate the integrated system's performance and inform the design of the pilot reactor.

Pilot Reactor (HESTIA): Targeting operation by 2034, the HESTIA pilot reactor is designed to demonstrate net electricity generation, long-pulse operation exceeding one year, and availability greater than 80%.

Commercial Reactor: Following the pilot phase, Helical Fusion aims to develop a 100 MWe-class commercial reactor by 2040, suitable for applications ranging from distributed power sources to large-scale centralized power generation.

Technological Platform and Innovation

Helical Fusion's technological advancements include:

Heliotron Design: Utilizing a stellarator-based heliotron design with continuously wound helical coils to achieve stable plasma confinement without the need for plasma current, reducing disruption risks.

High-Temperature Superconducting (HTS) Magnets: Development of the WISE conductor, a flexible HTS cable capable of being wound into complex coil shapes while maintaining superconducting properties. This innovation enhances the compactness and efficiency of fusion reactors.

Liquid Metal Blankets: Designing modular liquid metal blankets for efficient heat extraction and neutron shielding, essential for sustained fusion reactions.
