Fuse Energy
Pulsed-power fusion systems with a near-term radiation-testing business
The product
Pulsed-power and dense-plasma-focus systems that serve radiation-effects and high-energy-density-physics customers while advancing a MagLIF fusion roadmap. Current systems include the FAETON-I neutron source and 1 TW TITAN impedance-matched Marx generator; the planned 15 TW Z-Star facility is designed to combine 16 TITAN modules.
The thesis
Fuse is using national-security and commercial radiation testing to fund and exercise the same pulsed-power, neutron-generation and high-energy-density capabilities needed for fusion. Its five-year NNSS research agreement adds to existing collaborations with Sandia and Los Alamos, while a new Albuquerque site expands scarce U.S. radiation-testing capacity.
How it runs
Fuse builds and operates pulsed fusion radiation sources and sells nuclear-effects and radiation-hardness testing to defense, government-space, and commercial aerospace customers while using the shots and resulting data to advance its longer-term fusion-power program.
How it earns
Near-term revenue comes from radiation-testing campaigns and government development contracts, including an Air Force SBIR award; Fuse presents those testing revenues as funding and de-risking its path to commercial fusion. Customer pricing and contract values are generally undisclosed.
Why it wins
Its staged model monetizes the same pulsed-power and neutron-generation capabilities needed for fusion through scarce radiation-effects-testing services. FAETON's compact dense-plasma-focus source has completed a 140-plus-shot customer campaign and is offered to defense and commercial customers.
