Story of the Week

Scientists successfully replicate historic nuclear fusion breakthrough three times

Scientists in California shooting nearly 200 lasers at a cylinder holding a fuel capsule the size of a peppercorn have taken another step in the quest for fusion energy, which, if mastered, could provide the world with a near-limitless source of clean power.

Last year on a December morning, scientists at the National Ignition Facility at the Lawrence Livermore National Laboratory in California (LLNL) managed, in a world first, to produce a nuclear fusion reaction that released more energy than it used, in a process called “ignition.”

Now they say they have successfully replicated ignition at least three times this year, according to a December report from the LLNL. This marks another significant step in what could one day be an important solution to the global climate crisis, driven primarily by the burning of fossil fuels.

For decades, scientists have attempted to harness fusion energy, essentially recreating the power of the sun on Earth.

After making their historic net energy gain last year, the next important step was to prove the process could be replicated.

Brian Appelbe, a research fellow from the Centre for Inertial Fusion Studies at Imperial College London, said the ability to replicate demonstrates the “robustness” of the process, showing it can be achieved even when conditions such as the laser or fuel pellet are varied.

Each experiment also offers an opportunity to study the physics of ignition in detail, Appelbe told CNN. “This provides valuable information to the scientists in addressing the next challenge to be overcome: how to maximize the energy that can be obtained.
