Zap's next-generation Z-pinch fusion research machine, designed to demonstrate scientific breakeven using sheared-flow stabilization without magnets, cryogenics, or high-powered lasers. Plasma current flowing along a fuel column generates its own confining magnetic field, and a sheared axial flow suppresses instabilities that historically prevented Z-pinch from reaching fusion conditions. FuZE-Q achieved first plasmas in 2025 and is the primary platform for Zap's path to net energy gain.
A compact 50 MW liquid-metal-cooled fission microreactor announced in April 2026 as part of Zap's integrated nuclear strategy, combining near-term fission power delivery with long-term fusion development on a shared technology platform. The fission system is intended to generate near-term revenue and operational experience while Zap advances the fusion timeline. Zap is the first company to pursue a combined fission-fusion commercialization strategy under one roof.
