How BEST, EAST and Chengdu’s FRC Device Fit Into China’s Fusion-Energy Race

China’s next-generation fusion projects represent a change in emphasis. Earlier milestones focused on creating and controlling extremely hot plasma; the newer projects are intended to test whether that plasma can become part of a repeatable energy-producing system.

The most important caveat is timing. BEST’s proposed electricity demonstration around 2030 and Chengdu’s operating and neutron-production goals are project targets. Neither device is currently a commercial power plant.

EAST is the foundation, not a power station

The Experimental Advanced Superconducting Tokamak, or EAST, is China’s best-known “artificial sun.” In January 2025, it maintained a steady-state, high-confinement plasma for 1,066 seconds at temperatures above 100 million °C. The Chinese Academy of Sciences described the result as a major step toward fusion power generation. 39

That achievement demonstrated endurance and plasma control. It did not demonstrate net electricity. A fusion power plant would also need to extract heat, convert it into electricity, withstand neutron and heat loads, maintain components, manage fuel and operate reliably over repeated cycles.

EAST therefore matters because it supplies operating experience for the next engineering stage. The record shows that researchers can sustain relevant plasma conditions for much longer than a brief pulse; it does not by itself establish that a plant can produce more usable energy than the full facility consumes.

BEST is China’s bridge from experiment to electricity

The Burning Plasma Experimental Superconducting Tokamak, or BEST, is under construction in Hefei. Available reporting places expected completion around the end of 2027 and its first fusion-electricity demonstration around 2030. 21921

BEST’s significance is its intended role. It is designed to move beyond isolated plasma performance and test a more complete chain: burning-plasma behavior, confinement, fuel handling, heat removal and electrical output. Project descriptions also give a proposed fusion-power range of roughly 20 to 200 megawatts, although that is a design target rather than an achieved result. 2028

The phrase “first kilowatt-hour” can therefore be misleading if it is read as a promise of commercial electricity. A successful demonstration would be an important pilot milestone, but it would not show that fusion electricity is already economical or ready for widespread grid deployment.

A major part of BEST’s progress has been industrial rather than purely scientific. Two domestically developed superconducting magnets passed technical acceptance and full-load testing in 2026, while reporting said the project was moving toward final assembly. 1921 Those milestones illustrate the manufacturing and qualification burden behind a tokamak: the plasma chamber is only one part of the system.

Chengdu’s HHMAX-901 tests a different design

Chengdu’s HHMAX-901, associated with HH Fusion, follows a linear field-reversed-configuration, or FRC, approach. Unlike a conventional tokamak’s doughnut-shaped chamber, the reported device is a more-than-20-metre-long linear machine and has been presented as China’s first fusion device on that route. 36

The project has been described as targeting operation by the end of 2026. Reports also frame linear FRC systems as potential neutron sources for applications such as neutron imaging, nuclear medicine, materials work and nuclear-waste research. 38

Those applications could provide an earlier commercial use than electricity generation. But the distinction between a useful neutron source and a power plant is substantial. Claims about future neutron output, commercial performance or operating schedules remain targets until independently measured results are published.

FRC technology also faces unresolved power-plant questions: plasma confinement and gain, repetition rate, component lifetime, heat extraction and the ability to operate reliably at industrial scale. Its potentially compact and modular geometry is attractive, but its route to a dependable fusion plant is less established than the tokamak research base.

Why China is pursuing several fusion routes

China is not relying on a single machine or design philosophy. Research and commercial groups in Sichuan have been reported as exploring tokamak, linear FRC, inertial and magnetically driven fusion approaches. 10

That diversity reflects the uncertainty of fusion engineering. Tokamaks have the deepest experimental record, but they require complex superconducting magnets, demanding vacuum systems and plasma-facing components. Linear concepts may offer different engineering and commercial options, particularly for neutron production, but must still prove sustained confinement and power-plant performance.

The result is a portfolio strategy: EAST and BEST advance the tokamak path, while private and regional projects test alternatives that could eventually compete on size, construction speed, modularity or intermediate applications.

The real race is for an integrated industrial system

Fusion progress is often summarized by temperature or plasma duration. For a power plant, the harder problem is integration. The system must combine superconducting materials and magnets with specialty metals, ultra-high vacuum, cryogenics, plasma heating, diagnostics, power electronics, first-wall and divertor technologies, shielding, remote maintenance and safety systems.

BEST’s magnet program is a visible example of that shift from laboratory science to heavy engineering. The successful testing of a magnet is meaningful, but reporting has also cautioned that full assembly and long-term service testing under extreme conditions remain ahead. 2

This is why a plasma record and an electricity milestone should not be treated as interchangeable. A reactor can sustain plasma for a long time and still fall short on net plant energy, component durability, availability or operating cost.

Fusion’s first commercial products may not be electricity

Neutron sources could become an intermediate market for some linear-fusion projects. Reported possibilities include boron neutron-capture therapy, neutron imaging, isotope-related work, materials research and nuclear-waste treatment. 812

These uses would not prove that fusion power generation has arrived, but they could help companies build revenue, test hardware and develop expertise in radiation engineering, controls, electromagnetic compatibility and system qualification before attempting a power-producing facility.

The same supply chain may also support non-fusion industries. Superconducting magnets, cryogenics, precision power systems, vacuum equipment and radiation-resistant materials have potential relevance to medical and industrial equipment. The available sources support this broader spillover logic, but they do not provide enough authoritative evidence here to verify the specific claim that a domestically developed superconducting proton-therapy device treated its first clinical-trial patient in August 2026.

Capital is following the engineering opportunity

Private investment is expanding alongside public and institutional projects. One report counted 28 new Chinese fusion financing deals in the first half of 2026 and put sector financing at 7.268 billion yuan for that period. 51

That figure is a market report rather than proof of technical progress, and it should not be confused with government or industry procurement. Separate reporting put fusion-related procurement at roughly 10 billion yuan in 2026. 26

The investment pattern does, however, reinforce the broader shift: Chinese companies are forming around different technical routes and around the industrial capabilities needed to build them. The feedback loop runs in both directions—research creates engineering requirements, while industrial manufacturing and testing determine which scientific concepts can become repeatable machines.

What to watch next

The next meaningful tests are not simply whether a device reaches a higher temperature. They are whether projects can demonstrate:

• net energy performance at the relevant system boundary;
• repeatable plasma operation rather than a one-time pulse;
• durable first-wall, divertor and magnet systems;
• a workable deuterium–tritium fuel cycle and, eventually, tritium breeding;
• effective heat removal and electricity conversion;
• remote maintenance and acceptable component replacement times;
• safety, licensing and electromagnetic-compatibility performance; and
• a credible cost and availability case for grid electricity.

China’s fusion program is consequently best understood as an expanding engineering ecosystem, not as a finished energy technology. EAST supplied important long-pulse plasma experience. BEST is intended to connect that experience to a pilot electricity demonstration. Chengdu’s HHMAX-901 is testing a different linear route, with neutron applications potentially arriving before power generation.

If the projects meet their targets, they will mark progress toward fusion power. They will not, by themselves, prove that commercial fusion has reached the grid.
