Helical Fusion<\/strong> successfully completed the first commercial-scale High-Temperature Superconductor (HTS) coil<\/strong> test, advancing Japan further in the race for limitless and clean energy.<\/p>\n\n\n\n

Japan has marked another significant development in the field of nuclear fusion energy<\/strong>. The country’s leading startup, Helical Fusion<\/strong>, announced that it has successfully completed a large-scale performance test of its High-Temperature Superconducting (HTS) coil<\/strong>. This test was the first international demonstration where an HTS coil<\/strong>, manufactured at the size of a commercial reactor, was able to sustain stable current generation under superconducting conditions<\/strong>.<\/p>\n\n\n\n

Takaya Taguchi, CEO of Helical Fusion, stated at a press conference, “This means that the possibility of realizing fusion energy<\/a><\/em><\/strong> generation before the rest of the world has been proven.”<\/p>\n\n\n\n

The test was completed by achieving a stable superconducting current<\/strong> of 40 kiloamperes (kA)<\/strong> at a temperature of 15 Kelvin ($\\mathbf{-258^\\circ C}$)<\/strong> under a 7 Tesla magnetic field<\/strong>. The experiment was conducted at the facilities of Japan’s National Institute for Fusion Science (NIFS)<\/strong>.<\/p>\n\n\n\n

Helical Fusion<\/strong> will continue its research under the Helix Program<\/strong>. The company aims to complete performance tests of integrated “blanket\/divertor<\/strong>” systems with HTS magnets<\/strong> by the late 2020s. The next major step will be the construction of an integrated demonstration device called Helix HARUKA<\/strong>. This system is intended to prove that stable and continuous fusion reactions<\/strong> are practically possible.<\/p>\n\n\n\n

In the 2030s, the company plans to commission a pilot fusion facility<\/strong> named Helix KANATA<\/strong>. This facility is designed to meet the three fundamental criteria for commercial fusion: 24\/7 continuous operation<\/strong>, net positive electricity generation<\/strong>, and efficient component maintenance<\/strong>.<\/p>\n\n\n\n

Helical Fusion<\/strong>, as the only company to inherit NIFS’s helical fusion technology<\/strong>, aims to build the world’s first commercial fusion power plant based on this design. The helical “stellarator”<\/strong> structure provides a longer and more stable operation time compared to other fusion models by enabling continuous plasma confinement<\/strong> without the need for an external current driver. It is possible to think of the stellarator<\/strong> design as a more advanced version of tokamaks<\/strong>, another fusion design. However, this “advancement” also necessitates a much more complex fusion process.<\/p>\n\n\n\n
