Ten times a second, all day, every day—that's when fusion becomes power.
In Livermore, California, a startup called Inertia is attempting one of the most consequential translations in the history of energy: converting a laboratory triumph into an industrial process. Building on the ignition milestone achieved at Lawrence Livermore National Laboratory, the company is constructing what it calls the world's first fusion fuel factory, with the ambition of delivering clean, continuous electricity to the grid by 2035. The endeavor asks not merely whether fusion is possible, but whether it can be made ordinary enough to power a civilization.
- Decades after fusion was first imagined as humanity's ultimate energy source, a Livermore startup is now racing to turn a recent ignition breakthrough into a working production line — and the clock is running.
- The engineering demands are staggering: tiny fuel capsules must be manufactured at scale and a laser system must fire ten times per second, every second of every day, to cross the threshold from scientific milestone to functioning power plant.
- Political visibility is rising alongside technical ambition, with U.S. Representative Zoe Lofgren touring the facility and lending the project the rare compliment of calling it pragmatic — a signal that fusion is no longer a fringe bet in the halls of power.
- Inertia has set hard public deadlines — a fuel production line operational within a year, a gigawatt-scale plant breaking ground by 2030, and commercial grid power by 2035 — staking its credibility on a timeline with little room for drift.
Inside a nondescript building in Livermore, California, a company called Inertia is preparing to do something that has never been done before: manufacture fusion fuel on a factory floor. The effort builds directly on a landmark achievement at nearby Lawrence Livermore National Laboratory, where scientists proved that a fusion reaction could release more energy than was needed to ignite it. Inertia is now asking the harder question — can that proof of concept be made to work reliably, at scale, day after day?
The facility the company calls the "House of Fusion" is being converted into what Inertia describes as the world's first fusion fuel factory. The product is tiny capsules — fuel targets — that will be struck by the world's most powerful laser to trigger fusion reactions. Each capsule, the company says, holds more energy potential than two Falcon rockets. This is not a prototype effort. It is a production line.
Co-founder and chief scientist Dr. Annie Kritcher describes fusion's appeal in terms that carry unusual weight when spoken inside a facility actually building toward it: the energy is clean, producing no long-lived radioactive waste; it is abundant and cheap; and unlike solar or wind, it runs as baseload power regardless of weather. For a grid that must decarbonize without sacrificing reliability, that combination is difficult to replicate.
The technical demands are severe. Chief technology officer Mike Dunne outlined a precise roadmap: manufacturing processes developed by year's end, a full end-to-end production line operational within a year after that. But the laser system must also fire ten times per second, continuously — a cadence that separates a scientific demonstration from a functioning power plant.
CEO Jeff Lawson has committed publicly to breaking ground on a gigawatt-scale plant by 2030 and delivering fusion electricity to the grid by 2035. These timelines were stated plainly before elected officials and journalists, including U.S. Representative Zoe Lofgren, who toured the facility and called the plan pragmatic — high praise in the language of energy policy, where pragmatism implies not just theoretical soundness but genuine executability.
Inertia is not alone in the race toward commercial fusion, but it carries a distinctive advantage: proximity to, and continuity with, the national laboratory that proved ignition was possible. Whether the company can now prove that ignition is repeatable, manufacturable, and economically viable will become clearer in the eighteen months ahead.
Inside a nondescript building in Livermore, California, a company called Inertia is preparing to transform fusion from a laboratory curiosity into something far more consequential: a factory floor operation that manufactures the fuel for a new kind of power plant. The work builds directly on a breakthrough achieved nearby at Lawrence Livermore National Laboratory, where scientists recently demonstrated that fusion reactions could produce more energy than was required to ignite them—a threshold the field had chased for decades. Now Inertia is taking that proof of concept and asking a harder question: Can we make this work at scale, reliably, day after day, in a way that actually powers homes and cities?
The facility Inertia calls the "House of Fusion" will soon become something the company describes as the world's first fusion fuel factory. The transformation is not metaphorical. Over the coming months, the team plans to develop manufacturing processes for fusion fuel targets—tiny capsules that will be bombarded with the world's most powerful laser to trigger the fusion reaction. These targets, according to the company, contain more energy potential than two Falcon rockets. The scale of ambition here is worth pausing on: Inertia is not building a prototype. It is building a production line.
Dr. Annie Kritcher, the company's co-founder and chief scientist, frames the stakes in terms that have become familiar in climate and energy conversations, but which carry particular weight when spoken inside a facility actually attempting to solve the problem. Fusion energy, she explains, is clean—it produces no long-lived radioactive waste. It is abundant. It is cheap. And critically, it operates as baseload power, meaning it can run continuously regardless of weather, unlike solar and wind. For a grid that needs to decarbonize while maintaining reliable electricity supply, fusion offers something neither renewables nor traditional nuclear can quite deliver on their own.
The engineering challenge is immense. The company's chief technology officer, Mike Dunne, laid out the timeline with precision: by the end of this calendar year, the team will have developed the manufacturing processes. By this time next year, the entire facility will function as an end-to-end production line for fuel capsules. But manufacturing the fuel is only half the problem. The laser system itself must operate at a pace that seems almost absurd when you first hear it: ten times per second, continuously, all day, every day. That cadence is what transforms fusion from a laboratory achievement into a practical energy source. One shot every few hours is a scientific milestone. Ten shots per second is a power plant.
CEO Jeff Lawson articulated the vision plainly: the goal is to generate a continuous stream of energy capable of meeting humanity's electricity needs. By 2030, Inertia hopes to break ground on a gigawatt-scale power plant—a facility large enough to power roughly a million homes. Five years after that, in 2035, the company expects to begin feeding fusion-generated electricity into the grid. These are not tentative timelines hedged with caveats. They are public commitments made in front of elected officials and journalists.
On a recent Friday, U.S. Representative Zoe Lofgren toured the facility. Lofgren has been a consistent advocate for fusion research and development, and her presence underscored something important: this is no longer a fringe bet. It is receiving political attention and, implicitly, the kind of support that comes with it. She described the company's plan as pragmatic and said it made her hopeful. The language matters. In energy policy, pragmatism is a high compliment. It suggests a path that is not merely theoretically sound but actually executable.
What remains to be seen is whether Inertia can execute at the pace it has promised. The company is not the only fusion startup racing toward commercialization—there are dozens of others, backed by billions in venture capital and government funding. But Inertia has a particular advantage: it is building on work done at one of the world's premier national laboratories, just down the road. The National Ignition Facility at Lawrence Livermore proved that fusion ignition is possible. Now Inertia must prove that it is repeatable, manufacturable, and economically viable. The next eighteen months will be telling.

When you say they're converting the facility into a fuel factory, what does that actually mean? Are they building something new, or repurposing what's already there?
They're repurposing. The building already exists. What changes is what happens inside it—the equipment, the workflow, the purpose. Right now it's a research and development space. By next year, it becomes a production line. Same walls, completely different operation.
And these fuel targets—the capsules they're going to manufacture—how small are we talking?
Small enough to hold in your hand, but engineered to extraordinary precision. The energy density inside them is what matters. When the laser hits, the compression is so violent and so fast that it triggers fusion. The capsule itself is almost incidental to the physics, but manufacturing it consistently is everything.
Ten times per second sounds impossible. How do you even cool a laser system running at that pace?
That's the engineering problem they're solving right now. It's not just about the laser firing ten times a second—it's about the entire system cycling that fast without degrading. The materials, the optics, the timing. It's why they're being careful about the timeline. They're not guessing.
What happens if they miss their 2030 deadline for the power plant?
Then they're not the first fusion company to slip schedule. But the difference here is they're building on proven science from Livermore. They're not inventing the fusion reaction. They're scaling the manufacturing and the repetition. That's a different kind of problem—harder in some ways, but more solvable.
Why does Zoe Lofgren's visit matter? She's one representative.
She represents political permission. Fusion has been a punchline for decades—always thirty years away. Now a congresswoman is touring a facility and saying it's pragmatic. That changes the conversation in Washington. It changes funding conversations. It changes whether venture capital keeps flowing.
If they succeed, what does the grid look like in 2040?
Fundamentally different. Fusion as baseload power means you're not dependent on weather or time of day. You can retire coal plants. You can reduce the need for massive battery storage. You can actually decarbonize while keeping the lights on. That's the promise. Whether they deliver it is still an open question.
