Renaissance Fusion

Renaissance Fusion is a R&D company in fusion energy and high temperature superconductors HTS. The European Union's "Net Zero" strategy, combined with a doubling of the world's energy needs by 2050, has launched the race to develop concrete solutions to produce energy without greenhouse gas emissions. Renaissance Fusion's unique solution consists of a stellarator-type nuclear fusion reactor, designed as a modular composition, with a new generation of HTS magnets and liquid metal walls. The aim is to produce clean, safe and aboundant energy, limitating the use of non-renewable/critical raw materials and without using fossil fuels. 
 

We are providing infinite, continuous and clean energy to all the planet with zero carbon emission, bringing fusion energy on Earth. The unique solution of Renaissance Fusion is to realize safer, smaller and simpler fusion reactor, to be commercialized in the next decade. How? By developing groundbreaking fusion technologies like: an innovative stellarator reactor, manufactured using wide films of high temperature superconductors (HTS) for plasma magnetic confinement and liquid metals (LM) as internal walls, next to plasma. The aim is to build a reactor generating 1GW of electricity and to sell it to power plant builders (EDF, GE...). 

No fossil fuels nor critical raw materials will be used as fuel for the fusion reaction. Every step of our process produce valuable products and there are no radioactive waste. Neutrons produced at first treat fission waste and create scarce medical isotopes. A further increase in Q (difference in energy provided/produced) will pave the way to decarbonize industrial processes and maritime transport. Higher values of Q will unlock net electricity and combined applications of heat and electricity such as green hydrogen and the retrofit and upcycle of coal, gas and nuclear power-plants. Fusion will have a huge impact on society.

Fusion energy will be produced with an innovative stellarator, different from the experimental ones. A simpler geometry, thanks to disruptive technologies, will allow the magnetic confinement of the plasma in a smaller reactor and more powerful. The main features will be: i) innovative wide HTS films, deposited on modular cylinders of one meter diameter; ii) grooves on HTS, made by laser cut, constitute the 10T magnets which confine the plasma; iii) thick liquid metal walls around the plasma conduct the heat and absorb radiation emission. Inside the reactor, the deuterium et tritium feed the fusion reaction. The first one is aboundant in sea water and the second one is produced in the reaction. 
 

The core technologies are:

• the development of the stellarator with the determination of the best plasma configuration that is compatible with the performance of the magnets: the challenge being the control of the plasma, the correlation between simulation and experience, overall efficiency of the 1GW reactor;

• the development of 10T HTS magnets, obtained from wide HTS films with a new deposition technology, to reduce the size of the reactor and its construction cost;

• the development of liquid metal walls that encompass plasma and allow to:

- decrease the reactivity from neutrons and other ionizing particles (stop at least 99% of the neutrons generated in the reactor by the deuterium-tritium fusion reaction) to secure the reactor;

- evacuate the heat produced in the reactor to power the turbines and generate electricity;

- breed tritium (one of the two isotopes that fuse) to fuel the fusion reaction.
