ENN's "Xuanlong-50U" Device Successfully Achieves Hydrogen-Boron Fusion Reaction

In late September 2026, ENN achieved a major breakthrough in the commercialization of hydrogen-boron fusion: the “Xuanlong-50U” device achieved a hydrogen-boron fusion reaction. This is the first time a global commercial fusion company has achieved a hydrogen-boron fusion reaction on its own device, and also the first time China's magnetic confinement fusion device has achieved a clean neutron-free fusion reaction with advanced fuels (hydrogen-boron, deuterium-helium-3).

Hydrogen-boron fusion has commercialization advantages such as being neutron-free, having abundant and easily accessible fuel, and low cost. Its product is helium (α particles), but compared with deuterium-tritium fusion, it requires higher reaction temperature and triple product, and more demanding reaction conditions. In this experiment, the ENN fusion team, through the synergy of high-energy neutral beam injection and radio-frequency waves, greatly increased the non-thermal equilibrium fast proton fraction at the first resonance peak of the hydrogen-boron reaction, achieving a hydrogen-boron fusion reaction rate greater than 1.0E8/s. This indicates that ENN's hydrogen-boron fusion has entered the experimental stage related to burning plasma, marking a major breakthrough in China's multi-path fusion energy development.

More than ten authoritative fusion experts from research institutes and renowned universities in multiple countries around the world held a special review meeting on the results of this experiment and unanimously agreed that: this experiment achieved effective and reproducible measurement of the proton energy spectrum and the hydrogen-boron fusion reaction product α particles in a spherical torus device. The detection method is reliable and can support verification of hydrogen-boron fusion reactions. It is a milestone breakthrough in the innovative exploration and practice of hydrogen-boron fusion in spherical torus devices and has important value and contributions to global scientific research on magnetic confinement hydrogen-boron reactions.

ENN's fusion research and development takes commercialization implementation as its core driving force and systematically lays out five key technologies to address the core challenges of hydrogen-boron fusion: laying out hydrogen-boron reaction rate improvement technology to achieve "ignitable, high-gain" hydrogen-boron fusion through theoretical and experimental breakthroughs; developing high-parameter engineering technology to meet the engineering needs of commercial reactors; developing technologies related to high plasma temperature to meet the high reaction temperature requirements of hydrogen-boron fusion; developing direct power generation technology for the hydrogen-boron fusion product α particles to achieve efficient conversion of fusion energy into direct current electricity; developing fusion artificial intelligence technology to accelerate research and development speed and achieve intelligent steady-state operation of commercial reactors.

Looking to the future, ENN is implementing the commercialization of hydrogen-boron fusion through a "three-step" strategy: the first step is to achieve a hydrogen-boron fusion reaction by the end of 2026, and this goal has now been achieved ahead of schedule; the second step is to light the first lamp of hydrogen-boron fusion by 2030. The next-generation spherical torus device "Helong-2," which bears this mission, has already begun full-scale construction and is expected to be completed by the end of 2027; the third step is to achieve steady-state, high-power power generation before 2035 and enter the demonstration reactor stage.
