Inertia moves to commercialize one of the world’s most elaborate science experiments

Inertia Enterprises, a fusion power startup, announced on Tuesday that it has established three key agreements with Lawrence Livermore National Laboratory (LLNL) aimed at commercializing the innovative laser-based fusion reactor developed at the lab. These partnerships may provide Inertia with a competitive edge over other startups in the burgeoning fusion energy sector. The National Ignition Facility (NIF) at LLNL stands out as the first experiment to successfully demonstrate that controlled fusion reactions can yield more energy than is needed to initiate them. Inertia gained significant attention earlier this year with a $450 million Series A funding round, positioning itself as one of the most well-funded companies in the field. The collaboration between Inertia and LLNL focuses on inertial confinement fusion, a method that compresses a fuel pellet using external forces, diverging from other techniques that rely on powerful magnetic fields to sustain plasma until fusion occurs. At the NIF, a powerful array of 192 laser beams converges on a small gold cylinder known as a hohlraum, which houses a diamond-coated fuel pellet. Upon striking the hohlraum, the lasers vaporize it, releasing X-rays that compress the fuel pellet. This process transforms the diamond coating into plasma, which further compresses the deuterium-tritium fuel. For this technology to effectively generate grid power, these reactions must occur multiple times per second. The concept for this laser-driven reactor dates back to the 1960s, initially developed for research into thermonuclear weapons, but its potential for energy production was quickly recognized. Groundbreaking work on the NIF began in 1997, culminating in 2022 when the facility reached a critical milestone known as breakeven, where the fusion reaction produced more energy than was required to initiate it. Inertia is one of several startups, including Xcimer, Focused Energy, and First Light, that are striving to turn this scientific breakthrough into commercially viable power generation. Given that the NIF’s laser technology is based on older systems, there is optimism that newer laser technologies can enhance efficiency, thereby reducing the energy needed to ignite fusion reactions and facilitating the establishment of a profitable commercial power plant. The agreements with LLNL will see the two organizations collaborate on two strategic projects and one cooperative research and development initiative. Their joint efforts will focus on developing advanced laser systems and improving fuel targets to enhance performance and manufacturability. Additionally, Inertia is licensing nearly 200 patents from LLNL to further its mission. Annie Kritcher, co-founder and chief scientist at Inertia, played a pivotal role in designing the successful experiment at NIF that achieved scientific breakeven. The passage of the 2022 CHIPS and Science Act enabled Kritcher to establish her company while continuing her work at LLNL, marking an exciting evolution in the pursuit of fusion energy.
