France runs fusion reactor for record 22 minutes
Achieving the dream of commercial fusion power is the Holy Grail of engineering and has been for 80 years. With a single gram of hydrogen isotopes yielding the energy equivalent of 11 tonnes of coal, a practical fusion reactor would hold the promise of unlimited, clean energy for humanity until the end of time. France has upped the ante in the quest for fusion power by maintaining a plasma reaction for over 22 minutes – 25% longer than the previous record set by China in January 2025.
