Inertia Enterprises finds a way to make its fusion fuel fast
Fusion startup Inertia Enterprises has developed a manufacturing process to produce fusion fuel pellets in minutes rather than days. This breakthrough aims to transition fusion technology from experimental prototypes to mass-manufacturable commercial power sources.
Why it matters
Scaling fuel production is a critical bottleneck for commercial fusion energy, which is considered a potential solution for carbon-free base-load power.
Fusion startup Inertia Enterprises said it has found a way to cut the time it takes to make its fuel pellets from several days to just minutes.
By slashing fuel filling time, Inertia says it has knocked down one of the ten barriers it must overcome to deliver the first phase of its commercial power plant ambitions. The startup gave TechCrunch an exclusive first look at the process.
The advance was not guaranteed: Investors gave Inertia $450 million on the premise that it could commercialize technology developed at the National Ignition Facility (NIF), which is an elaborate science experiment that requires painstaking care and feeding to operate. At the NIF, making fuel pellets can take a week or more and cost a small fortune. That’s not a great recipe for a profitable operation.
