![]() “Hydrogen is found in water so the stuff that generates this energy is wildly unlimited and it is clean.” ![]() “Unlike coal, you only need a small amount of hydrogen, and it is the most abundant thing found in the universe,” Julio Friedmann, chief scientist at Carbon Direct and a former chief energy technologist at Lawrence Livermore, told CNN. Tritium is rarer and more challenging to obtain, although it can be synthetically made. The deuterium from a glass of water, with a little tritium added, could power a house for a year. Fusion projects mainly use the elements deuterium and tritium – both of which are isotopes of hydrogen. Scientists around the world have been studying nuclear fusion for decades, hoping to recreate it with a new source that provides limitless, carbon-free energy – without the nuclear waste created by current nuclear reactors. Nuclear fusion happens when two or more atoms are fused into one larger one, a process that generates a massive amount of energy as heat. ![]() What is nuclear fusion and why does it matter? Nuclear fusion is a man-made process that replicates the same energy that powers the sun. Here are key things to know about today's announcement - and possible next steps: Scientists at Lawrence Livermore National Laboratory’s National Ignition Facility have made history by successfully producing a nuclear fusion reaction resulting in a net energy gain, a breakthrough hailed by US officials as a “landmark achievement” and a “milestone for the future of clean energy.” (Jason Laurea/Lawrence Livermore National Laboratory) ![]() NIF Target Area operators inspect a final optics assembly during routine maintenance at Lawrence Livermore National Laboratory’s National Ignition Facility. ![]()
