The brief
- Pacific Fusion develops pulser fusion using rapid high-energy electrical pulses to compress and heat fuel to fusion conditions.
- Founded in 2023; raised $1+ billion Series A led by General Catalyst.
- Broke ground August 2026 on demonstration facility in Albuquerque; targets net gain by 2030.
Technical approach
Pulse generation
Impedance-matched Marx generators
Specialized high-voltage pulse generators create intense, coordinated pulses. Impedance matching nearly doubles efficiency vs. existing systems.
Fuel compression
Inertial confinement approach
Electromagnetic pulses create magnetic field around fuel target, squeezing it to extreme density and temperature for fusion.
System design
Modular, manufacturable architecture
156 identical pulser modules; each has 32 stages of 10 bricks. Each brick: 2 capacitors + 1 switch. Designed for mass manufacturing.
