The non exclusive licence covers tritium compatible hardware for firing frozen hydrogen pellets into plasmas, a mechanism no current injector can run at reactor scale.
A frozen hydrogen pellet, a few degrees above absolute zero, fired at high speed into a 100-million-degree plasma: that is how a deuterium–tritium fusion reactor eats. The hard part is not the plasma. It is keeping it fed.
Under a non-exclusive agreement, Oak Ridge National Laboratory (ORNL) licensed four tritium-compatible cryogenic inventions to Type One Energy, the lab said. The deal hands the Tennessee-based fusion startup a pellet gas gun, a screw extruder for plasma energy pellet injection, a pressure-relief device, and a single-phase-change solid conveyance for cryogenic extrusion recirculation.
ORNL says pellet fuelling reaches the plasma core more effectively than gas puffing. The lab also notes that no current pellet injector produces pellets at the rates a reactor would need, framing the four technologies as filling that gap. Deuterium–tritium reactors must be continuously refuelled, and tritium's scarcity and radioactivity make the hardware harder than ordinary hydrogen plumbing.
Type One Energy is based in the same city as ORNL and has previously worked with the lab on a high-heat-flux test facility and on the Department of Energy's Innovation Network for Fusion Energy (INFUSE) programme. ORNL Director Stephen Streiffer called the licence "an exciting next step" in the partnership.
The licence is research-stage tech transfer. Commercial pellet-rate targets, deployment milestones, and a reactor timeline are not part of the announcement.
