It is called the "energy of the stars" and perhaps represents the future of clean energy. Yesterday, in France, scientists maintained a plasma for 22 minutes, far exceeding the latest Chinese nuclear fusion record, a method opposed to fission, used in power plants around the world.

The French tokamak WEST maintained a stable fusion reaction for more than 22 minutes (1,337 seconds), thus exceeding by 25% the previous world record, held by China. The stability of the plasma was maintained with a heating power of 2 megawatts. This progress marks a new key step for the commercial exploitability of fusion energy, the next step being to maintain plasma for several hours. Nuclear fusion is the subject of research [...] This artic…

CEA Claims Nuclear Fusion Energy Record for Plasma Duration

Feb. 18, 2025 — French research organization CEA reported that on 12 February, the CEA’s WEST tokamak maintained a nuclear fusion plasma for more than 22 minutes, a 25 percent improvement over the previous record. “This leap forward demonstrates how our knowledge of plasmas and technological control of them over longer periods is becoming more […]
