Shaanxi Xinghuan Energy Technology

Startorus Fusion is developing compact and scalable fusion power devices based on a high-field spherical tokamak approach that uses high-temperature superconductors. A key feature of their technical route is the use of repeated magnetic reconnection for plasma heating, a method intended to enable stable and efficient energy output within a compact device. The company's business model integrates research and development, design, and operation and maintenance of these commercial fusion reactors. Its objective is to provide clean, reliable energy to the grid. The company operates on a rapid iteration cycle of "operating one generation, constructing one generation, and conducting preliminary research for one generation" to accelerate development.

The company's first experimental device, SUNIST-2, was developed jointly with Tsinghua University and has been operational since 2023. This device has been used to validate their magnetic reconnection heating concept. Startorus Fusion is currently designing its next-generation device, which will utilize high-temperature superconducting magnets to confine plasma and aims to achieve fusion conditions by raising plasma temperatures to 100 million degrees. The company has a workforce of over 100 employees, with a high concentration of post-graduate degree holders in fields like plasma physics, nuclear engineering, and electrical engineering. In January 2026, Startorus Fusion raised approximately $140-$143 million in a Series A funding round, a record for China's private fusion sector, with participation from state-owned funds and other institutional investors. This capital is allocated towards the development of its next-generation fusion devices. The company's roadmap targets engineering validation around 2028, with the goal of delivering a grid-capable fusion demonstration plant by approximately 2032.
