Fusion Energy Milestone
Fusion Energy Milestone
December 2022
On December 5, scientists at Lawrence Livermore National Laboratory (LLNL) conducted the first controlled nuclear fusion experiment in history to produce more energy than was used to drive it. The U.S. Department of Energy hailed this achievement as “a major scientific breakthrough decades in the making that will pave the way for advancements in national defense and the future of clean energy.”“LLNL’s experiment delivered 2.05 megajoules (MJ) of energy to the target, resulting in 3.15 MJ of fusion energy output, demonstrating for the first time a most fundamental science basis for inertial fusion energy,” LLNL said. Many advanced science and technology developments still are needed to commercialize fusion energy.
Investing in the next generation of affordable, carbon-free technologies that can operate 24/7 is critical to delivering a resilient clean energy future. EEI and our partners in the Carbon-Free Technology Initiative long have advocated for continued funding and research for advanced nuclear fission and fusion. Learn more.
