Stellarex is a fusion energy development firm that uses a simplified Stellarator and milestone‑driven demonstrators to validate systems integration, de‑risk scale‑up, and execute a staged technology roadmap from prototypes through demonstration devices to commercial fusion power plants. It's running two device programs - SXA (intermediate prototype) and SX0 (net‑energy demonstrator) - run in parallel from 2026 through 2032, anchored by the launch of the Centre for Fusion Energy.
