About the Company

Pacific Fusion

Modular pulsed-fusion energy system

Pacific Fusion works to develop commercially viable nuclear fusion energy. It uses pulsed magnetic inertial fusion to squeeze and heat small deuterium-tritium fuel capsules with fast, high-current pulses inside a compact fusion chamber, aiming to achieve net energy gain where the output exceeds the input. The system is highly modular: a fast electric pulser built from thousands of identical parts, a small fusion chamber, and many tiny fuel containers, enabling affordable manufacturing, rapid iteration, and simpler supply chains. This focus on practical economics helps distinguish it from competitors that may pursue less manufacturable designs. The company’s goal is to deliver limitless, clean, on-demand power to meet growing global energy demand and help address climate change.
