ENN claims first hydrogen-boron fusion reaction by a commercial firm on Xuanlong-50U

ENN Group said its Xuanlong-50U (EXL-50U) spherical torus achieved a hydrogen-boron (proton-boron) fusion reaction at a measured rate above 10^8 per second — the first such claim among commercial fusion firms. The shot combined neutral-beam injection with radio-frequency waves; the next-step Helong-2 (EHL-2) is under construction for completion around end-2027.

• Hydrogen-boron reaction rate exceeded 10^8 per second
• Method: neutral-beam injection plus radio-frequency waves
• Helong-2 (EHL-2) under construction, completion around end-2027
• Targets: 2030 first light, steady power before 2035
