Their discoveries about fuel retention and the problematic role of carbon in trapping fuel are paving the way for more efficient fusio Apr 16, 2025 · Fusion energy would transform the energy landscape. But beyond the Nov 21, 2024 · An artist’s interpretation of spin-aligned atoms during the process of fusion. Jan 12, 2025 · The way scientists think about fusion changed forever in 2022, when what some called the experiment of the century demonstrated for the first time that fusion can be a viable source of clean energy. Jul 28, 2024 · Fusion has often been criticised for always being '10 years away' The project to build a nuclear fusion reactor in Nottinghamshire has been described as the "UK's Nasa moment". The experiment, at Lawrence Livermore National Laboratory, showed ignition: a fusion reaction generating more energy out than was put in. Jun 2, 2025 · Fusion power has long been promised as a clean, abundant energy source, but scientists have struggled to harness it effectively. That doesn’t mean replacing all power plants overnight—but it does mean making real, impactful progress in reducing emissions while meeting global energy needs. May 12, 2025 · Unfortunately, the larger problem with fusion energy remains that, in practice, it still takes more energy to run the whole system than the reaction gives back. Credit: Kyle Palmer / PPPL Communications Department Researchers have developed a method to enhance fusion energy efficiency by optimizing fuel mixtures and employing spin polarization. However, one persistent challenge has slowed progress: the inability to reliably contain the high-energy particles Mar 30, 2023 · In this technology assessment, we've developed policy options that could help address such challenges. Mar 22, 2025 · A cleaner, mercury-free process to isolate lithium-6, a key fusion fuel ingredient, was discovered by accident using a water-filtering material.
