Researchers at a US federally funded research center have achieved a second successful nuclear fusion reaction experiment, resulting in a net energy gain. The Lawrence Livermore National Laboratory (LLNL) announced that scientists at the National Ignition Facility (NIF) surpassed their December breakthrough with a higher energy yield, as reported by Reuters.
The process of nuclear fusion closely mirrors the phenomenon that allows stars to emit light and heat. By employing a laser targeted at fuel, the scientists merged two light atoms into a denser one, releasing a substantial amount of energy. This approach holds great promise as a sustainable, low-carbon energy source to combat climate change.
In the previous December experiment, the laser delivered 2.05 megajoules to the target, resulting in fusion ignition and 3.15 megajoules of energy output, yielding around 1.1 megajoules net energy, equivalent to 0.31kWh, enough to power a 50-watt LED TV for six hours.
While the exact net energy yield from the latest experiment conducted on July 30th remains undisclosed, LLNL spokesperson informed Reuters that researchers are still analyzing the final results.
Although there is still a significant distance to cover before fusion ignition can become a practical mainstream energy production option for powering homes, this successful replication of the experiment and surpassing previous results marks a positive step forward for clean energy research.
