GenF at VivaTech 2026 : Inertial Fusion Enters the Industrial Era

GenF at Vivatech 2026
Inertial Fusion Enters the Industrial Era
From June 17 to 20, 2026, GenF is proud to take part in VivaTech, Europe’s largest event dedicated to technological innovation and startups, held at Paris Expo, Porte de Versailles. This 10th edition is a unique opportunity to meet our teams and discover our vision for inertial fusion energy
A Historic Moment for Nuclear Energy
Humanity faces an unprecedented equation: massively decarbonizing our energy mix while meeting a global electricity demand that could double by 2050. Renewables, although essential, will not be enough on their own to deliver dispatchable, dense and continuous power.
Nuclear fusion, which replicates the reactions at the heart of stars, offers an unmatched promise:
- Virtually unlimited energy from abundant fuels (deuterium, lithium)
- Zero CO₂ emissions during operation
- No risk of runaway reaction and no long-lived high-level waste
- An unrivaled energy density serving industrial sovereignty

The GenF promise: laser inertial fusion, faster and simpler
Born from the French ecosystem of excellence (Thales, CEA, CNRS), GenF is developing a direct-drive inertial fusion approach, leveraging recent breakthroughs in high-power lasers and PCSEL diodes. Our architecture aims to:
- Radically simplify reactor engineering compared with magnetic approaches
- Capitalize on the industrial maturity of laser components and cryogenic targets
- Accelerate time-to-market with a roadmap aligned with the European fusion strategy and France 2030 priorities
- Build a sovereign value chain, from tritium breeding to thermal conversion systems
Our ambition is clear: to deliver the first commercial inertial fusion electricity within the next decade.
Come and meet GenF at VivaTech
VivaTech 2026 will gather the global ecosystem of tech, startups, AI and green technologies in Paris. Whether you are an investor, industrial partner, public stakeholder, researcher, talent, or simply curious about fusion, our teams will welcome you at our booth to:
- Discover our technology and demonstrator
- Discuss industrial and scientific partnership opportunities
- Explore career openings within GenF
- Share our vision of a Europe leading the fusion race
📍 Join us June 17–20, 2026
