China Accelerates ‘Artificial Sun’ Fusion Ambitions, Targeting Experimental Reactor by 2035

China has set an ambitious target to complete an experimental fusion reactor, widely referred to as its “artificial sun,” by 2035, paving the way for commercial fusion power in the decades that follow. The announcement highlights the country’s determined push to harness nuclear fusion as a cornerstone of long-term energy security and technological self-reliance.

The timeline supports the development of the China Fusion Engineering Test Reactor (CFETR), a next-generation tokamak facility intended to bridge the gap between experimental research and practical electricity generation.

Construction milestones are advancing steadily, with expectations for an industrial prototype around 2035 and broader commercial deployment targeted for approximately 2050. This builds on significant progress at existing facilities, particularly the Experimental Advanced Superconducting Tokamak (EAST) in Hefei.

EAST, often called China’s “artificial sun,” has achieved multiple world records in recent years. Researchers have reported breakthroughs in high plasma density, surpassing previous limits through advanced operating modes and plasma self-organization. The facility has also sustained high-confinement plasma for more than 1,066 seconds and operated at temperatures exceeding 100 million degrees Celsius, conditions far hotter than the Sun’s core.

Fusion energy holds the potential to transform global power generation by offering a clean, abundant alternative to fossil fuels and conventional nuclear fission.

China’s fusion program enjoys strong state backing, integrated into national science and technology strategies, including the latest Five-Year Plan. Projects such as the HL-3 tokamak complement EAST and reflect a coordinated effort across research institutions and state enterprises.

While significant technical challenges remain, such as achieving sustained net energy gain, developing materials that can withstand extreme conditions, and ensuring cost-effective scaling, China’s consistent experimental successes have positioned it as a frontrunner in the international fusion race, alongside major collaborative projects like ITER.

Images shared alongside recent reports show President Xi Jinping beside a large tokamak device featuring the Chinese national flag, underscoring high-level political support for advancing fusion as a strategic priority.

If realized, commercial fusion could reshape the global energy landscape by providing reliable, low-carbon power on a massive scale and helping to end energy scarcity. As timelines tighten, the next decade will prove decisive in determining whether fusion transitions from promising laboratory results to practical reality on the power grid.
