Technology Assessment & Commercial Milestones
Spin-out of Max-Planck IPP (Wendelstein 7-X). In early 2026 signed a landmark agreement with RWE, the Free State of Bavaria and IPP to build the world's first commercial stellarator power plant — Stellaris — on the site of a retired fission plant.
Thesis: Inherit the world's best operating stellarator dataset (W7-X) and combine it with modern HTS coils and AI-driven optimisation.
Key engineering bottlenecks: HTS coil manufacturing in non-planar geometry; Divertor heat exhaust in stellarator topology.
Recent milestones: 2024 — €20M seed; 2025 — €185M Series A — Europe's largest fusion round; Early 2026 — RWE / Bavaria / Max Planck agreement for Stellaris.
Device pipeline: Alpha demonstrator → Stellaris pilot.
Timeline: Net gain in the 2030s; Stellaris at former Gundremmingen fission site.
