Fuse Energy Technologies

Fuse Energy Technologies pursues magnetised liner inertial fusion (MagLIF) using pulsed-power generators inspired by Sandia's Z-machine, but mass-produced for repetitive operation. The architecture targets laser-fusion-class gain at a fraction of the driver cost.

Pulsed-power MagLIF can match laser fusion gain at a fraction of the driver cost.

Global electricity demand is entering an unprecedented growth phase driven by AI infrastructure, data centers, transport electrification, industrial decarbonization, water desalination, and advanced manufacturing. Solar suffers intermittency, wind capacity-factor variability, natural gas carbon emissions, conventional nuclear cost and deployment speed, and batteries energy-density and duration limits. The world requires a new source of clean, dispatchable baseload energy. Fusion represents the ultimate energy source — the challenge is making it commercially practical.

MagLIF combines axial magnetic field, laser preheat, and pulsed-power compression of a metal liner. Sandia has demonstrated the physics; Fuse aims to industrialise the pulsed-power driver for power-plant duty cycles.

Deuterium-tritium fusion releases ~80% of its energy as 14.1 MeV neutrons, which deposit their kinetic energy in a surrounding blanket. The heat drives a conventional steam (Rankine) or supercritical-CO₂ (Brayton) turbine.

The most thoroughly understood fusion fuel cycle, highest cross-section at achievable temperatures, and proven back-end engineering (steam turbines are 19th-century technology). Trade-offs: neutron-induced materials damage, tritium handling, ~33–40% Carnot-limited efficiency.

Pulsed-power switches and capacitors follow well-understood industrial learning curves; MagLIF's economics improve roughly linearly with switch repetition rate and liner manufacturing throughput.
