Fusion has promised the world limitless clean power. But too often it fails a much simpler test: can it generate electricity at a price that makes commercial sense?
We are developing the centrifugal mirror, a compact steady state fusion machine designed to be simpler to build and maintain and so delivering cost effective power.
Electricity demand is accelerating, driven by AI, electrification and economic growth. At the same time, advances in vacuum and high-voltage technology have made the centrifugal mirror viable.
The opportunity now is to turn proven science into economically viable fusion power.
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.
For decades, fusion has meant increasingly complex machines. The centrifugal mirror takes the opposite approach.
High voltage spins the plasma, while centrifugal force confines it, shear suppresses instability and friction provides heat. One mechanism replaces multiple systems.
The result is a machine just over ten metres long that operates continuously, can be maintained in weeks, and uses existing materials and suppliers.
Fewer systems. Greater reliability. Longer-lasting components. Lower-cost electricity.
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’s next machine GF1 is designed to close the gap between proven physics and a power plant.
The design is complete and costed, with suppliers, sites and regulators already engaged. It is the next step towards commercially viable fusion.
Gridfire engineers helped build CMFX, the world’s first steady-state superconducting centrifugal mirror, achieving first plasma in 18 months with $5M of US Department of Energy funding.
Its fusion results were measured, peer reviewed and published.
