Gridfire is the only team positioned to make economic fusion a reality.
Whilst fusion is magical, we care about a single, basic outcome; the lowest $ cost per unit of fusion energy.
Global energy demand is accelerating as emissions, grid instability, and geopolitical pressures intensify. Fusion promises carbon-free, baseload power at enormous scale — but only when science and execution align.
At Gridfire, we only entered fusion following deep analysis of the global ecosystem — from regulation to deployment readiness. We believe the technology has reached a true inflection point.
We are the core team behind the pioneering — ARPA-E funded — Centrifugal Magnetic Mirror at the University of Maryland.
Joined by world-leading plasma physicists, materials scientists, and fusion engineers, we bring deep experience building and operating fusion machines — with a shared belief that compact systems can deliver grid-scale fusion at a world-leading price.
Fusion has long relied on massive, complex machines requiring decades of R&D and enormous capital. Gridfire takes a different approach: economical fusion must be simple, maintainable, rapidly iterable, and powerful.
Our approach is a modern evolution of a proven idea — the Centrifugal Magnetic Mirror.
By extending a well-established principle from tokamak physics — increased confinement through sheared rotation — the centrifugal mirror delivers a step-change in performance through:
And the result is simple: Truly economic fusion power
Gridfire is building a practical path to fusion energy. We welcome engagement from partners, investors, and collaborators who share our ambition to deliver clean, reliable power at global scale.
Gridfire is developing its second-generation machine with clear milestones to validate physics and prove scalability toward commercial fusion—backed by strong IP and detailed cost analyses through full power plants.
