At Renaissance Fusion we build stellarators (from ‘stella’, Latin for ‘star’) - the most efficient, steady, and stable fusion reactors on Earth.
With unique High Temperature Superconducting (HTS) magnets and liquid metal shields, we bring stellarators out of the lab and onto the grid.
1. Direct deposition of HTS coils: a large surface, for instance a cylinder, is directly coated with several superconducting films.
2. Direct patterning of HTS coils: the surface is then engraved by laser ablation to create 1D/2D coils
3. Simplified assembly of stellarator coil winding surfaces: toroidal array of patterned cylinders generates the 3D stellarator field.
4. Neutron shielding and heat extraction:
cylinders are coated with flowing liquid metals
Who we are
As the first magnetic‑confinement fusion start‑up launched in continental Europe, we operate in a region that concentrates up to 40% of the world’s fusion talent, laboratories, and universities — and that, with ITER, has fostered a uniquely powerful ecosystem of related industries.
“We’re rebels rooted in solid science,
we think creatively outside the box
and re-invent engineering
under economic constraints.”
Global energy demand set to rise
to nearly 30% by 2050*
AI and data centres are driving a major surge in electricity demand, set to roughly double in the next few years and climb even higher after.
To meet the net zero emissions goals of the Paris Agreement, a clean, safe and abundant energy source is needed to complement renewables and storage.
Fusion can deliver it.
