About

Zephyr Fusion is building the first in-orbit fusion power source: a megawatt-class reactor enabling large-scale industry in space, at a fraction of the cost of equivalent solar. Founded by former physicists from Lawrence Livermore and Oak Ridge National Laboratories, Zephyr leverages decades of fusion research to deliver a compact magnetic confinement system designed to take advantage of the space environment.

Powering tomorrow's industrial revolution in space

Zephyr Fusion announces plans to provide megawatt-class power in orbit using a dipole magnetic confinement fusion reactor powered by high-temperature superconductors, enabling large-scale in-space industrial activity. The company targets space-based power for a growing space economy, arguing fusion in orbit reduces hardware and launch costs while enabling MW-scale power for satellites, propulsion, data centers, and habitats.
