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 in continental Europe, we work in a region that is home to 40% of the world’s talent, labs, universities in the field and with ITER, has fostered a unique 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 will at least double by 2050*

To meet net zero emissions goals, a safe, abundant, 24/7 energy source is needed to complement renewables and storage.

Fusion is that source.
