Pacific Fusion's Demonstration System is a pulser-driven inertial fusion machine that aims for net facility gain by 2030, with fusion bursts above 100 MJ. The company broke ground on a $1 billion-scale research and manufacturing campus in Albuquerque in August 2026.
New to fusion? Nuclear fusion, explained: three ways to bottle a star
Current state
| Status | Under construction |
| Country | United States |
| Location | Mesa del Sol, Albuquerque, New Mexico |
| Developer | Pacific Fusion |
| Developer type | Private |
| Concept | Pulsed-power inertial |
| Fuel | D-T |
| Purpose | Demonstration |
| Net energy target | 2030 |
| Site | Groundbreaking at Mesa del Sol, Albuquerque, August 2026 |
| Private funding raised | USD 900m (as of 2024-10) |
Notes
net energy target 2030 is 'net facility gain' (fusion yield > total energy stored in the machine), stricter than target gain but not Q_eng/electricity. private funding raised is the Series A commitment, released in milestone tranches; aggregators report total commitments above $1bn by June 2026 (unverified).
Timeline
- 2024-10 — Pacific Fusion emerged from stealth with a milestone-tranched Series A commitment of more than $900 million led by General Catalyst. (source)
- 2026-02 — Pacific Fusion and Sandia National Laboratories reported a simplification of pulser-driven ICF in joint experiments. (source)
- 2026-08-24 — Pacific Fusion broke ground on its Albuquerque campus to house the Demonstration System. (source)
The timeline is append-only: corrections are added as new entries. Stated targets appear in the current-state table, never as milestones.
