Design point published with independent technical backing
Data confidence: Medium-high
Overview
- Confinement
- Z-pinch (sheared-flow stabilized)
- Fuel cycle
- D-T / D-D
- Development stage
- Prototype operating
- Key milestone
- Feasibility study for pilot plant at Centralia, WA retired coal site
- Target first commercial power
- Mid-late 2030s (est.)
- Notes
- Compact, low-capex approach; good potential Grid Fit candidate for smaller ex-BESS parcels — verify footprint.
