China says it will generate its first electricity from nuclear fusion around 2030 — after two 582-tonne toroidal field magnets, the largest superconducting magnets ever built for a fusion device, passed full-load testing in July 2026. Behind that date sit two "artificial suns": the EAST tokamak in Hefei, world record holder for sustaining a 100-million-degree plasma for 1,066 seconds, and the HL-3 tokamak in Chengdu, which has pushed atomic nuclei to 117 million degrees Celsius — nearly eight times hotter than the Sun's core. Let’s break down how a tokamak actually works, what China's fusion records really mean, the roadmap from 2027 to 2050 — and the honest catch nobody mentions. #NuclearFusion #ArtificialSun #FusionEnergy

Humanity stands on the threshold of a new energy era. In Hefei, eastern China, the next-generation "artificial sun" known as BEST is designed to transform fusion from a science experiment into a real-world power source. Standing for Burning Plasma Experimental Superconducting Tokamak, the reactor’s mission is to achieve “burning plasma,” where the fusion reaction generates its own sustaining heat. This is essential for the industry's holy grail: net energy gain. Targeting a 20 to 200 megawatt output (enough to power tens of thousands of households), BEST plans to demonstrate electricity generation by 2030. As a member of ITER—the world’s largest international fusion project in France—China contributes key components and shares research outcomes. Operating within frameworks like the “Hefei Fusion Declaration,” BEST serves as an open platform, pooling data and resources to accelerate the global transition to abundant, zero-carbon energy. This collaboration is proving that fusion is no longer just a distant dream, but a viable future solution.

So how do you confine a superhot, 100M°C fusion plasma? With superstrong magnets, of course. 🧲 We've now installed three of the 18 toroidal field (TF) magnets needed for our SPARC fusion demonstration machine. TF magnets are one of the three major magnet types we'll use in SPARC (the others being the poloidal field and central solenoid magnets) to corral the plasma once the machine is operating. Because plasma is made up of charged particles, it responds to a magnetic field. It's a technique refined over dozens of earlier tokamaks built around the world that manage this highly energetic cloud of particles that's hotter than the center of the sun. #SPARC #Magnets #FusionEnergy

Here we go… This is the moment our ST40 centre column is lifted out. A bit like open-heart surgery on a tokamak. It’s a delicate operation, and a huge milestone for ST40. The centre column has had a tough life, acting as the core of the toroidal magnetic field coil in the world’s highest-field spherical tokamak. After more than 5,000 plasma pulses, it has helped generate magnetic fields above 2 Tesla at the plasma core, confining plasma at temperatures of more than 100 million °C, the threshold for #fusion. Next up, we install the new and improved centre column built by our partners at The Rockwood Group. This is all part of ST40’s major upgrade programme with U.S. Department of Energy and Department for Energy Security and Net Zero, helping transform it into one of the most reactor-relevant fusion devices in the world. What began as an experimental tokamak is becoming something much bigger: a customer testbed for the technologies and expertise needed to put #fusionenergy onto the grid⚡ And for anyone wondering what the centre column actually does… 👇 It forms the inner limb of each turn of the toroidal field coil. Its 24 wedges each carry up to 200 kA of current, generating the powerful magnetic fields needed to confine the plasma. Wrapped around the wedges, a 192-turn central solenoid helps drive and sustain the plasma current, after merging-compression start-up. An impressive piece of equipment with an equally impressive track record! #Fusion #FusionEnergy #Innovation

China just dropped another quiet bombshell in the tech race: its “Artificial Sun” fusion project is no longer a lab curiosity, it’s becoming an integrated industrial ecosystem. The U.S. talks about fusion breakthroughs. China builds the supply chain. In the Yangtze River Delta alone: • superconductors from Shanghai • armor materials from Zhejiang • insulation systems from Jiangsu • 60% of reactor components made locally • an alliance that grew from 60 → 300 companies in 3 years • ITER-level demand fueling domestic upgrades This is what the West still doesn’t get: Fusion won’t be won by a single experiment, it will be won by the civilization that can manufacture the future at scale. China isn’t just chasing fusion, it is industrializing it. Different strategies. Different time horizons. Different destinies. The U.S. is racing for a breakthrough. China is racing to make the breakthrough commonplace.

The "Golden Man" is a testament to the cooperation and friendship between China and France. As representatives of two great civilizations, East and West, the friendship between China and France has a long history. 35 years ago, China and France began their cooperation in nuclear energy. Since then, the close cooperation between CGN and EDF has never ceased. From jointly building the Daya Bay Nuclear Power Plant, a handcrafted megawatt-class nuclear power plant in mainland China, to jointly building the EPR global reactor Taishan Nuclear Power Plant, and then to jointly developing three major nuclear power projects in the UK, the cooperation between the two sides has continued to deepen, yielding fruitful results in nuclear energy cooperation. Today, the nuclear energy cooperation between China and France has ushered in an unprecedented historical opportunity. CGN and EDF will join hands to embark on a new journey, creating a new chapter from the "Golden Man" to the "Golden Age".

New year, new major milestone: We have completed, delivered, and mounted our first magnet for SPARC inside Tokamak Hall ✅ 🧲 . The significance of this toroidal field (TF) magnet achievement can't be overstated. In many ways, its story is the CFS story. Back when the company started in 2018, some thought creating a TF magnet with high-temperature superconductor (HTS) was a farfetched idea. But our founders' resolve to develop this key innovation unlocked our new pathway to a smaller, more economical fusion power plant. This toroidal field (TF) magnet is one of 18 that'll be threaded around the vacuum vessel to help tame and confine the superhot plasma once our SPARC tokamak is operational. The vacuum vessel, the donut-shaped container at the heart of the machine as devoid of air as outer space, offers the extreme conditions needed for fusion. The TF magnets help create a magnetic bottle, confining the fusion plasma to keep it away from the vessel walls that would cool it down.

$Elon Musk just exposed the most catastrophic energy blindspot in the entire AI arms race. The West is still debating which twigs to burn. China is capturing the sun. Musk: “People just don’t understand how solar is everything. Compared to the sun, all other energy sources are like cavemen throwing some twigs into a fire.” Every natural gas plant. Every nuclear reactor. Every experimental fusion project being debated in Washington right now. Twigs. Musk: “We have a giant free fusion reactor that shows up every day. It’s farcical for us to create little fusion reactors.” And then he gave the most clarifying statistic in the entire energy debate. Musk: “The sun is over 99.8% of all mass in the solar system. Jupiter is around 0.1%. So even if you burnt Jupiter, the energy produced by the sun would still round up to 100%.” Musk: “And then if you teleported three more Jupiters into our solar system and burnt them too, it would still round up.” The sun is not an energy source. It is the only energy source. Everything else is rounding error. China already knows this. While American tech executives beg for permits to build natural gas plants, China crossed 1,000 gigawatts of installed solar capacity in 2025. More than the rest of the world combined. They are not holding summits about it. They are not commissioning reports about it. They are building it. Harvesting the free fusion reactor that arrives every morning at zero cost and feeding it directly into their AI data centers. The AI race is not an algorithm race. It is an electro-industrial race. You cannot build superintelligence without infinite compute. You cannot have infinite compute without infinite energy. And right now, the United States is losing the energy war while holding committee meetings about which twigs to burn next. China built the energy-compute flywheel. Cheap, scalable, infinite solar power feeding AI models at a fraction of the cost. Compounding every single day. The nation that captures the sun’s output will hold a permanent monopoly on global intelligence. The nation that doesn’t will spend the next decade trying to understand how it lost. Everyone else gets left holding the twigs.$
