Inertia Enterprises has reduced the production time for fusion fuel pellets from one week to approximately three hours. The startup developed this manufacturing process through a public-private partnership with the Lawrence Livermore National Laboratory. This advancement addresses a primary barrier to scaling fusion technology from laboratory experiments to commercial power generation.

Commercial fusion plants require a high volume of fuel pellets to operate continuously, with Inertia projecting a need for ten pellets per second. By accelerating production and reducing the required tritium inventory, the company aims to lower operational costs and safety risks associated with handling radioactive isotopes. These manufacturing efficiencies are intended to support the development of a viable, large-scale fusion energy grid.

Fusion power startup Inertia Enterprises reduced the fuel filling process from a week to just a few hours. It's one of 10 hurdles the company must overcome to make a profitable power plant.

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 10 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.
