What: Renaissance Fusion is developing a nuclear fusion reactor that it hopes will provide clean and affordable energy by the next decade. The Grenoble-based company is part of a wave of Deep Tech companies that are hoping to harness nuclear fusion, long a theoretical research dream, and turn it into a commercial service. Renaissance is conducting research on High Temperature Superconducting (HTS) magnets, liquid metal, and the stellarator (a plasma device that potentially could be the housing for nuclear fusion reactions). Renaissance is betting that by combining these three technologies, it can create small, modular reactors that are stable and generate low-cost energy while producing minimal radioactive waste.

Why: Nuclear power plants today use the fission process, which has the advantage that it does not create carbon emissions. But fission generates large amounts of radioactive waste, and the health and cost impacts around such plants remain controversial, limiting their adoption. Fission supporters believe their technology can replace that with a safer and cheaper fusion system.
