Pacific Fusion
🇺🇸 US · Founded 2023 · Active
Pacific Fusion is a US company founded in 2023, headquartered in California, developing what it calls pulser fusion: very fast, high-current electrical pulses squeeze small containers of deuterium-tritium fuel until they fuse, a form of inertial confinement fusion. Its pulsed power driver is based on the impedance-matched Marx generator, co-invented by its chief technology officer. In October 2024 it announced a Series A of about $900 million led by General Catalyst, committed in stages as undisclosed technical milestones are met. It chose Albuquerque, New Mexico, for a research and manufacturing site to house its Demonstration System, which it says is designed to reach net facility gain, meaning more fusion energy out than all the stored energy put in, and broke ground there in August 2026. It has run target experiments at Sandia National Laboratories.

$900m of equity is committed in stages against milestones rather than received, and is not counted as raised.
Terms
- Magneto-inertial
- Compression of a magnetised plasma; sits between MCF and ICF in density and timescale.
- Deuterium–tritium
- Lowest ignition threshold; 80% of energy in 14.1 MeV neutrons. The reference fuel for every near-term net-gain claim.
