Pacific Fusion

Pacific Fusion is a fusion energy company founded in 2023 and based in Fremont, California. The company aims to provide abundant, affordable, and clean energy through commercial fusion power. It specializes in designing and building pulsed magnetic fusion systems, utilizing pulser technology to deliver controlled bursts of electrical energy that drive fusion reactions. The core technology of Pacific Fusion is the next-generation impedance-matched Marx generator (IMG), co-invented by cofounder and CTO Keith LeChien. This technology combines multiple IMG modules to create a pulser system that generates powerful electric currents, compressing fusion fuel targets to the necessary conditions for fusion ignition. The company is actively testing production-scale pulser modules and plans to build a demonstration system by 2030, aiming for net energy gain from fusion. Pacific Fusion collaborates with General Atomics to enhance its development efforts. The company has raised significant funding, including a $900 million Series A round in 2024, indicating strong investor confidence in its mission and technology.
