This is a historic milestone in the quest for a clean nuclear energy source.

Scientists at Lawrence Livermore National Laboratory in California have made a major breakthrough in the field of nuclear fusion, sparking hope for a new carbon-free power source.

How did they do it?

The breakthrough came in an impossibly small slice of time, less than it takes a beam of light to move an inch. In that tiny moment, nuclear fusion as an energy source went from far-away dream to reality. The world is now grappling with the implications of the historic milestone. For Arthur Pak and the countless other scientists who’ve spent decades getting to this point, the work is just beginning.

Pak and his colleagues at Lawrence Livermore National Laboratory are now faced with a daunting task: Do it again, but better—and bigger.

That means perfecting the use of the world’s largest laser, housed in the lab’s National Ignition Facility that science-fiction fans will recognize from the film “Star Trek: Into Darkness,” when it was used as a set for the warp core of the starship Enterprise. Just after 1 a.m. on Dec. 5, the laser shot 192 beams in three carefully modulated pulses at a cylinder containing a tiny diamond capsule filled with hydrogen, in an attempt to spark the first fusion reaction that produced more energy than it took to create. It succeeded, starting the path toward what scientists hope will someday be a new, carbon-free power source that will allow humans to harness the same source of energy that lights the stars.

Lawrence Livermore National Lab fires 192 lasers at a fuel pellet and yields 1.5 times more energy output than input, a fusion breakthrough.

Technology developed at Argonne can help narrow the field of candidates for molten salts, a new study demonstrates.

Scientists are searching for new materials to advance the next generation of nuclear power plants. In a recent study, researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory showed how artificial intelligence could help pinpoint the right types of molten salts, a key component for advanced nuclear reactors.

The ability to absorb and store heat makes molten salt important to clean energy and national climate goals. Molten salts can serve as both coolant and fuel in nuclear power reactors that generate electricity without emitting greenhouse gases. They can also store large amounts of energy, which is increasingly needed on an electric grid with fluctuating sources such as wind and solar power.

The three major lessons on energy security.

On October 19, European Commission president Ursula von der Leyen announced that the EU had replaced two-thirds of its Russian gas imports since February by switching to other suppliers. Such a turnaround seemed unattainable last spring when the invasion of Ukraine turned Moscow from an EU business partner into a military threat.

Despite the EU’s reduction of its energy dependence on Russia, there is work to be done in the long term. To achieve autonomy from Russian energy, the Union could learn from the experience of one of its members, Lithuania – a country which, since declaring its independence from the USSR in 1990, has been able to adapt to a complex geopolitical context to ensure its energy security.

Fusion News overblown.

NEW YORK, Dec 13 (Reuters Breakingviews) — A fusion breakthrough unveiled on Tuesday by the U.S. Department of Energy is a scientific tour de force, and a commercial irrelevancy.

It’s a notable feat that researchers produced more energy from fusing atoms together than they used to start the process. The development has been an elusive goal since the 1930s, promising essentially limitless power from cheap hydrogen found in seawater. One gram of hydrogen theoretically contains as much energy as burning about 10 tons of coal.

U.S. Department of Energy.

The U.S. Department of Energy said on December 13, 2022, that for the first time – and after several decades of trying – scientists have managed to get more energy out of the process than they had to put in.

After six decades we have finally reached controlled fusion “ignition.” Here is how it works and what it means (and doesn’t mean):

At the Lawrence Livermore National Lab (LLNL) the National Ignition Facility (NIF) starts with the Injection Laser System (ILS), a ytterbium-doped optical fiber laser (Master Oscillator) that produces a single very lower power, 1,053 nanometer (Infrared Light) beam. This single beam is split into 48 Pre-Amplifiers Modules (PAMs) that create four beams each (192 total). Each PAM conducts a two-stage amplification process via xenon flash lamps.

Surpassing energy breakeven at US facility constitutes a “Wright brothers moment” for fusion research, say researchers.

Scientists have been striving to achieve fusion ignition for decades.

Scientists from the Lawrence Livermore National Laboratory (LLNL) announced a major breakthrough for nuclear fusion on Tuesday, December 13. In a historic first, they achieved fusion ignition during a nuclear fusion experiment. This means they produced more energy than they put into their fusion experiment, paving the way for practically limitless clean energy production from nuclear fusion.
