The Fusion Energy Race: ITER to KSTAR — 2026-09-28
China's BEST compact tokamak moved into hardware delivery mode this week, with the first batch of toroidal-field coil cases shipped from Deyang on September 27. A Tsinghua-affiliated startup secured a nine-figure yuan capital injection, and on the sidelines of a manufacturing conference industry figures anchored a 2030 target for fusion's "first light." Meanwhile, US and Korean activity spanned rock-bottom-budget magnetic mirrors and plans for around-the-clock fusion plants.

BEST tokamak's toroidal-field coil cases delivered in batch
On September 27, a completion-and-shipping ceremony was held at the Deyang base of China National Machinery Industry Heavy Equipment (国机重装) for the first batch of TF (toroidal field) coil cases for BEST — the Burning plasma Experimental Superconducting Tokamak, described as the world's first compact fusion energy experimental device. TF coil cases are the metal load-bearing housings that contain and support the superconducting magnets, and suppliers say the handover opens up an industrial manufacturing chain for fusion-reactor core components. Guoji Zhongzhuang also signed a batch manufacturing contract with ASIPP for BEST shielding blocks, expanding the partnership from single components to broader systems. BEST is positioned as the device filling China's gap between "experimental" and "demonstration" reactors.
Industry anchors 2030 for fusion's "first light" as BEST targets end-2027
At the World Manufacturing Convention, industry participants said BEST is scheduled for completion by the end of 2027, with the sector aiming to see "the first lamp lit by fusion" around 2030. The report highlights China's multi-device strategy: EAST in Hefei has achieved stable high-confinement operation at 100 million degrees for over a thousand seconds, while Chengdu's HL-3 (China Torus III) has passed "double 100-million-degree" operation and is expected to run burning-plasma experiments in 2027. This tracks alongside ITER's continued progress and record private fusion fundraising internationally.
Tsinghua-linked startup Startorus Fusion gets ¥100 million boost
Startorus Fusion (星环聚能), a "Tsinghua-affiliated" fusion unicorn, received a ¥100 million capital injection, Singapore's Lianhe Zaobao reported on September 27. The company builds on spherical tokamak foundations with repeated short-pulse "firing" cycles using magnetic reconnection heating — a deliberate departure from the traditional approach of sustaining hot plasma for long durations, aiming to make fusion reactors smaller.
Terra Fusion spins plasma with salvaged parts and a shoestring budget
IEEE Spectrum (about five days ago) profiled Terra Fusion's magnetic mirror reactor, which is pursuing breakeven energy production using secondhand components on a minimal budget — a deliberately lean contrast to the multi-billion-dollar programs at ITER and Commonwealth Fusion Systems. It's a small story financially, but notable as evidence that alternative confinement concepts are still attracting players far outside the megacap startup tier.
Energy venture cash flows — sometimes beyond fusion
Capital and Concrete's weekly energy digest (September 21 edition) captured a busy financing week: Samsung C&T put $100 million into Kairos Power, EnableFusion raised a $33 million Series A, and Bechtel exited TerraPower — alongside a breeder blanket overview relevant to fusion reactor design. It's a reminder that fusion supply chains and component industries are increasingly drawing capital through adjacent fission and grid deals.
Local view
Korean media are framing the next phase of KSTAR as a quest for a "24-hour fusion power plant." Money Today's September 27 feature — "We will build the unextinguishing artificial sun" — quotes stakeholders noting that global fusion companies are currently focused on how high a plasma performance they can achieve, with round-the-clock operation as the decisive next bet. In China, the funding story for Startorus Fusion was carried by Zaobao's China finance desk. Chinese tech and industry outlets — IT之家 via Sohu, iFeng, and Sina's real-time science tracker — all covered the September 27 BEST TF coil case shipment, emphasizing that supplier Guoji Zhongzhuang has now established an engineering-grade manufacturing chain for fusion reactor core components. Also notable: an academician-level reality check from Peng Xianjue carried by NetEase Science — that fusion only counts as energy if cost per kilowatt-hour ultimately works out.
Context & numbers
- ¥100 million: the capital injection into Startorus Fusion reported September 27.
- $33 million: EnableFusion's Series A; $100 million: Samsung C&T's investment into Kairos Power
- End-2027: BEST completion target; 2030: the industry-anchored date for fusion's "first light"
- 100 million °C for over 1,000 seconds: EAST's steady-state high-confinement benchmark cited at the convention; HL-3 burning-plasma experiments expected in 2027
- For scale, Commonwealth Fusion Systems' SPARC is roughly 80% complete with net-energy-gain targeted for 2027
On the radar
- October 2026: Watch whether the US NRC publishes its final rule for fusion machines — a regulatory milestone flagged by Venture Atlas, alongside the FY2027 Fusion Energy Sciences budget request
- Late 2026–2027: SPARC operational window; CFS has said the machine at Devens targets first plasma around then, shaping how the private race compares to ITER's 2039 D-T schedule
- BEST next steps: with TF coil cases now shipping, expect further magnet-system deliveries and assembly milestones ahead of the end-2027 completion target
- Rumor watch: Korean coverage hints that next-generation KSTAR campaigns will target significantly longer plasma durations to support DEMO-type operation planning — treat specific new records as unconfirmed until KFE officially announces fall campaign results
