About

Zephyr Fusion is an early-stage nuclear fusion company targeting the decarbonization of industrial heat — the process heat used in steel mills, cement plants, chemical facilities, and other heavy industries that collectively account for approximately 20% of global CO2 emissions. While most fusion programs target electricity generation, Zephyr's approach focuses on delivering high-temperature heat (>1000°C) directly to industrial processes, potentially displacing fossil fuel combustion in applications where electrification is difficult or impossible. The company is developing a compact fusion device designed for co-location with industrial facilities.
