A new era for nuclear fusion: the french stellarator innovation

A stellarator capable of operating without interruptions has been discovered in France, a technology that could revolutionize the energy sector: with an advanced design and HTS superconductors, this reactor promises efficiency and continuity

The French outfit Renaissance Fusion is developing continuous operation capability with a very different approach called a stellarator, which offers a unique solution for sustainable and uninterrupted energy generation.

Whereas the more traditional varieties of tokamak reactors rely on pulsed operation and internal currents, stellarators confine plasma steadily using three-dimensional magnetic fields. The icing on the cake with this particular stellarator is its efficiency: where laser fusion takes up to 100 kWh to develop a mere 1 kWh of energy, this new stellarator requires only 2-3 kWh to achieve the same result.

A compact, sleek system

The entire new system is based on three key components:

• HTS magnets, which increase the intensity of the magnetic fields. Liquid metal shielding for the reactor walls and optimization of cooling. An improved stellarator design for consistent and continuous operation.
• With more powerful and durable magnets, Renaissance Fusion has significantly reduced the volume of the plasma, hence coming up with a smaller reactor that can be economically viable.
• The liquid metal shield efficiently captures the heat produced in the fusion process, strengthening the magnetic fields at the same time. This makes the reactor not just compact but also very efficient.

Aiming for the future of Global Energy

It is for this model that Renaissance Fusion is now building a nuclear fusion power plant. If this stellarator-based approach proves successful, then global energy research will be revolutionized, opening the door to a new era of clean, continuous power.
