Startorus Fusion is a Chinese fusion developer founded in 2021. Its programme combines spherical tokamaks with repetitive magnetic-reconnection heating. It participates in SUNIST-2 with Tsinghua University and develops NTST, CTRFR-1, HTS magnets and associated instrumentation.

Reviewed 17 October 2026. Design targets, experimental reports and issuer statements are distinguished below.

Origins and locations

Startorus was founded in 2021, initially operating in Shaanxi, with Rui Chen and Yi Tan leading business and technical development.[1][2] By 2026, reports identified the company with Shanghai and its Jiading experimental base; company materials also retained a Xi’an address.[3][4]

Research programme

Its approach combines spherical tokamaks, repetitive reconnection heating and HTS development.[5][6] Tsinghua University designed and led SUNIST-2, with Startorus participating through collaboration and technology transfer. The July 2023 announcement reported initial plasma current of 100 kA; the design current was 0.5 MA. These should not be confused.[7]

In 2026, SUNIST-2 was operating, NTST was under construction, and CTRFR-1 was in development.[4] An August investor update described component manufacture and a full-size HTS toroidal-field magnet test at 20 K and 4.5 kA.[8] Future equivalent-Q and power-export milestones remain company plans. Associated electronics products include pulsed power, signal conditioning and data acquisition; product delivery does not establish commercial fusion electricity production.[4]
