Proxima Fusion

The world’s growing demand for energy urgently requires clean, safe, and scalable solutions. Fusion energy, the process that powers the stars, represents the ultimate goal: a limitless, carbon-free source of energy. Yet, achieving stable and continuous fusion on Earth has remained one of humanity’s greatest engineering  challenges.

Proxima Fusion was founded to overcome this barrier by building the first generation of quasi-isodynamic (QI) stellarator fusion power plants. Building on decades of research in magnetic confinement and leveraging advances in computational design and high-temperature superconducting magnets, the company aims to turn fusion from a scientific dream into an industrial reality. 

Proxima Fusion is pioneering an entirely new model for fusion power plants based on quasi-isodynamic stellarators.

This model stands out for its ability to maintain a continuously stable plasma, avoiding the typical instabilities found in tokamak reactors. Their disruptive approach relies on a unique combination of three key technological pillars:

• advanced magnetic field optimization.
• high-performance computational design.
• next-generation high-temperature superconducting (HTS) materials.

Additionally, Proxima Fusion is the first-ever spin-off from the Max Planck Institute for Plasma Physics, allowing it to directly merge cutting-edge academic research with an industrial and entrepreneurial mindset.
 

The development of fusion power plants by Proxima Fusion could transform the global energy landscape.

The company aims to deliver energy that is clean (zero greenhouse gas emissions), safe (no long-term radioactive waste and no meltdown risk), and abundant (capable of meeting growing global electricity demand).

This contribution directly supports several of the United Nations' Sustainable Development Goals (SDGs), particularly:

• SDG 7: Affordable and Clean Energy
• SDG 13: Climate Action

Proxima Fusion will leverage Dassault Systèmes’ 3DEXPERIENCE platform to accelerate the development of stellarator-based fusion power plants.

By creating a high-fidelity virtual twin, the company will be able to simulate and validate designs, optimize multi-physics performance, and plan complex manufacturing and assembly processes.

The platform will also provide end-to-end digital continuity, ensuring that engineering, simulation, and operations are seamlessly connected, while enabling secure collaboration with suppliers and research partners.

Proxima Fusion places a strong emphasis on collaborative and collective intelligence.

As a spin-off of the Max Planck Institute, the company benefits from the expertise of leading plasma physicists. Its team includes top-tier researchers, complex systems engineers, and experts in computer science and data.

Proxima Fusion also engages in scientific partnerships to publish fusion plant concepts, reflecting a transparent and collaborative development model.

Furthermore, the company launched the “ConStellaration Challenge” in partnership with Hugging Face, aimed at optimizing stellarator design through artificial intelligence and machine learning. This open challenge is a clear demonstration of their commitment to tapping into global talent to accelerate the energy transition.
