Renaissance Fusion

About

Founded in 2021, Renaissance Fusion is a private headquartered in Fontaine, France with approximately 50-200 employees specializing in Fusion.

Renaissance Fusion is a magnetic confinement fusion company pioneering the development of stellarator reactors. The company leverages three core technology pillars: stellarators (the most efficient, steady, and stable fusion reactor design), high-temperature superconducting (HTS) magnets for direct coil deposition and patterning, and liquid metal shields for neutron shielding and heat extraction. Founded as the first magnetic confinement fusion startup in continental Europe, Renaissance Fusion is positioned in Grenoble, a region hosting 40% of global fusion expertise, research laboratories, and universities in the field, as well as ITER. The company is developing innovative manufacturing approaches including direct HTS coil deposition on large cylindrical surfaces, laser-patterned coil designs, and simplified assembly methods. Their technology aims to bring stellarators from research laboratories to commercial power generation.
