Since 2022 Nuclear Fusion Breakthrough, US Researchers Have More Than Doubled Its Power Output

The U.S. Department of Energy’s National Ignition Facility (NIF) has achieved significant advancements in its net-positive fusion experiment, increasing energy yields from 3.15 megajoules in 2022 to 8.6 megajoules in recent attempts. While these results demonstrate the potential of controlled nuclear fusion, none of the experiments have yet produced enough power to contribute to the grid or offset the facility’s energy consumption, as the initial net-positive shot required 300 megajoules solely for the laser system. Nevertheless, these findings provide evidence that controlled fusion is a viable scientific pursuit.
