Pacific Fusion has a staff that knows its way around pulsers and inertial fusion, and an ongoing collaboration with General Atomics. Today, the two companies are announcing plans to test Pacific Fusion’s pulser-driven inertial fusion energy concept, with commercial fusion power as the goal.

“We are building a fusion machine and testing all equipment—including components and a pulser module—at our Pacific Fusion test center,” Pacific Fusion cofounder and chief technology officer Keith LeChien told Nuclear News. “GA’s engineering expertise remains an important part of our progress, and we expect this collaboration to continue through future phases of development.”

Pacific Fusion predicts “1,000-fold leap” in performance, net facility gain by 2030

Inertial fusion energy (IFE) developer Pacific Fusion, based in Fremont, Calif., announced this morning that it is on target to achieve net facility gain—more fusion energy out than all energy stored in the system—with a demonstration system by 2030, and backs the claim with a technical paper published yesterday on arXiv: “Affordable, manageable, practical, and scalable (AMPS) high-yield and high-gain inertial fusion.”

With more than 40 fusion development companies announcing plans and funding, it’s hard for a newcomer to stand out, but Pacific Fusion is giving it a try. The company, based in Fremont, Calif., was founded in summer 2023 and emerged from “stealth mode” last Friday with $900 million in committed funding from investors, a team that includes people directly involved in the successful ignition experiments at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), and a technical paper that makes a case for a pulsed magnetic fusion approach to fusion energy.
