Chinese private energy company ENN (新奥) has announced a major breakthrough in hydrogen-boron (p-B11) fusion commercialization, using its 'Xuanlong-50U' (玄龙-50U) magnetic confinement device. This marks the first time a global commercial fusion company has achieved hydrogen-boron fusion on its own device, and the first time a Chinese magnetic confinement fusion device has used advanced fuels (hydrogen-boron, deuterium-helium-3) for clean, neutron-free fusion. Hydrogen-boron fusion offers advantages such as no neutron radiation, abundant and cheap fuel, and low cost, producing only helium (alpha particles). However, it requires higher reaction temperatures and triple product conditions than deuterium-tritium fusion. ENN's team used a synergy of high-energy neutral beam injection and radiofrequency waves to significantly increase the non-thermal equilibrium fast proton share at the first resonance peak of the hydrogen-boron reaction, achieving a fusion reaction rate greater than 10^8 per second. This indicates ENN's hydrogen-boron fusion has entered the burning plasma experimental stage, representing a major breakthrough in China's multi-path fusion energy development, as reported by Science and Technology Daily.
Source report
ENN's "Xuanlong-50U" device achieves hydrogen-boron fusion reaction, marking a global first for a commercial fusion company.
Recently, a major breakthrough in hydrogen-boron fusion commercialization was achieved by ENN: the "Xuanlong-50U" device successfully realized a hydrogen-boron fusion reaction. This marks the first time a global commercial fusion company has achieved a hydrogen-boron fusion reaction on its own device, and also the first time a magnetic confinement fusion device in China has achieved a clean, neutron-free fusion reaction using advanced fuels (hydrogen-boron and deuterium-helium-3).
Key Advantages and Challenges
Hydrogen-boron fusion offers several commercial advantages:
- Neutron-free reaction
- Abundant and easily accessible fuel
- Low cost
The reaction product is helium (alpha particles). However, compared to deuterium-tritium fusion, hydrogen-boron fusion requires:
- Higher reaction temperatures
- Higher triple product requirements
- More stringent reaction conditions
Technical Achievement
ENN's fusion team achieved this milestone by synergizing high-energy neutral beam injection with radiofrequency waves. This approach significantly increased the proportion of non-thermal equilibrium fast protons at the first resonance peak of the hydrogen-boron reaction, achieving a hydrogen-boron fusion reaction rate greater than 10⁸ per second.
Significance
This achievement indicates that ENN's hydrogen-boron fusion has entered the experimental phase related to burning plasma. It represents a major breakthrough in China's multi-path fusion energy development.
