Fusion is the process that powers the sun and stars. Stellarex Energy is advancing a made‑in‑Canada fusion capability – providing sustainable, reliable, and affordable power that builds on the country’s nuclear and tritium expertise, strengthens national energy security and industrial competitiveness, and supports a carbon‑free future.
Stellarex Energy combines commercial and business expertise with more than 120 years of combined leadership in fusion science and engineering across laboratories in the USA, UK, Germany, and France.
Stellarex leverages a simplified Stellarator approach to reduce technical risk and uses staged demonstration devices to validate technology, de‑risk scale‑up, and accelerate the commercial deployment of fusion power.
Why Fusion?
All forms of energy on Earth originate from fusion. By harnessing this same process, fusion energy offers a transformative path toward clean, abundant, and dependable power at global scale.
Produces energy without carbon emissions during operation, supporting deep decarbonization of the global energy system.
Fusion reactions cannot run out of control; if operating conditions change, the reaction naturally shuts down.
Delivers continuous, reliable power—unaffected by weather, seasons, or time of day.
Uses fuel derived from widely available resources, offering a virtually limitless energy source.
Generates no long-lived radioactive waste, reducing long-term environmental and storage challenges.
Designed to meet growing global energy demand, from regional grids to large-scale power systems.
