One year ago today, researchers at Lawrence Livermore National Laboratory achieved a record shot at the National Ignition Facility (NIF) that set the world talking about the potential of fusion energy. And the buzz hasn’t stopped. Fusion energy is getting its most significant attention yet on the world stage at COP28 in Dubai, UAE, where John Kerry, U.S. special presidential envoy for climate, delivered a keynote address today titled “An inclusive fusion energy future,” followed by a panel discussion.

Focused Energy and Lawrence Livermore National Laboratory have signed a strategic partnership project agreement that will allow LLNL—home of the National Ignition Facility (NIF)—to help the company develop and assess isochoric compression target designs for inertial fusion energy. Focused Energy announced the news on November 7.

Focused Energy and Xcimer Energy are two of the eight fusion developers the Department of Energy selected in late May for funding under the public-private Milestone-Based Fusion Development Program, and the only developers using an inertial confinement concept. The Milestone program, announced in September 2022, was open to any fusion developer willing to undergo a competitive merit-review process, regardless of fusion confinement concept. But the prospects for inertial fusion concepts might have gotten a boost from Lawrence Livermore National Laboratory’s December 2022 achievement of scientific breakeven at the National Ignition Facility (NIF), which was announced shortly before the application window for the Milestone program closed.

Lawrence Livermore National Laboratory hosted current and former staff, government officials, and media on May 8 to celebrate the lab’s achievement of fusion ignition at the National Ignition Facility (NIF) on December 5, 2022. Energy secretary Jennifer Granholm and undersecretary for nuclear security and National Nuclear Security Administration administrator Jill Hruby were in attendance, and Granholm took the opportunity to announce funding of up to $45 million to support inertial fusion energy (IFE) research and development. The Department of Energy’s Office of Science (DOE-SC) wants to establish multiple IFE Science and Technology Innovation Hubs (IFE S&T hubs), with total funding for 2023 of up to $9 million for projects lasting up to four years in duration.

Ignition and net gain at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) in December 2022 focused global attention on the prospects of inertial fusion energy (IFE). First Light Fusion and the U.K. Atomic Energy Authority (UKAEA) acknowledged the achievement as they announced plans on January 25 to design and build a demonstration facility known as Machine 4 at UKAEA’s Culham Campus in Oxford, U.K., using First Light’s “projectile approach” to IFE. Construction is expected to begin in 2024, and operations are “likely to commence” in 2027.

It’s official: Early in the morning on December 5 at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), the laser-triggered implosion of a meticulously engineered capsule of deuterium and tritium about the size of a peppercorn yielded, for the first time on Earth, more energy from a fusion reaction than was delivered to the capsule. The input of 2.05 megajoules (MJ) to the target heated the diamond-shelled, spherical capsule to over 3 million degrees Celsius and yielded 3.15 MJ of fusion energy output. The achievement was announced earlier today by officials and scientists representing the Department of Energy and its National Nuclear Security Administration, the White House, and LLNL during a livestreamed event.

Just over one year ago, on August 8, 2021, researchers achieved a yield of more than 1.3 megajoules (MJ) at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) for the first time, achieving scientific ignition and getting closer to fusion gain.

The scientific results of the historic experiment were published exactly one year later in three peer-reviewed papers: one in Physical Review Letters and two (an experimental paper and a design paper) in Physical Review E. In recognition of the many individuals who worked over decades to enable the ignition milestone, more than 1,000 authors are included on the Physical Review Letters paper.

One of the last remaining milestones in fusion research before attaining ignition and self-sustaining energy production is creating a burning plasma, where the fusion reactions themselves are the primary source of heating in the plasma. A paper published in the journal Nature on January 26 describes recent experiments at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) that have achieved a burning plasma state.

Lawrence Livermore National Laboratory is celebrating the yield from an experiment at the National Ignition Facility (NIF) of more than 1.3 megajoules of energy—eight times more than the yield from experiments conducted this spring and 25 times more than NIF’s 2018 record yield.

Inside a new steel-clad facility nicknamed “The Citadel,” First Light Fusion has installed a 22-meter two-stage gas gun—the third-largest such component in Europe.
