Pacific Fusion Begins Construction on New Mexico Demonstration Facility Aiming for Net Facility Gain

Pacific Fusion has started building a new facility in Albuquerque, New Mexico, aimed at reaching a critical milestone in nuclear fusion: generating as much energy as the overall facility consumes. The startup, established in 2023, is targeting net facility gain by 2030 as a foundational step toward deploying a commercial fusion power plant in the mid-2030s.

What Happened

On Tuesday, Pacific Fusion broke ground on its demonstration facility in New Mexico. According to Carrie von Muench, co-founder and chief operating officer, the site represents a novel project in the country focused on net facility gain. While prior experiments—notably at the National Ignition Facility—have produced controlled reactions that generated more energy than the reaction itself absorbed, no system has yet produced sufficient power to cover the entire facility’s operational energy usage.

The decision to construct the site follows successful component trials earlier this year, where Pacific Fusion tested a one-third-scale pulser module that discharged 440 gigawatts of peak power in 80 nanoseconds.

Key Highlights

• Target Milestones: Pacific Fusion plans to achieve net facility gain by 2030 and aims to have an operational commercial power plant by the mid-2030s.
• Technical Methodology: The system deploys powerful, synchronized electrical pulses to generate a magnetic field around a pencil-eraser-sized fuel target, compressing it until fusion takes place.
• Scale and Infrastructure: The demonstration unit will integrate 156 pulser modules. Each module contains 32 circular stages composed of 10 bricks, with each brick housing two power-storing capacitors and one switch.
• Energy and Output: Chief technical officer Keith LeChien stated that each pulse is intended to produce roughly 100 megajoules, which is approximately ten times the output of the National Ignition Facility.
• Operational Pace: The Albuquerque demonstration plant will conduct a handful of test shots per day, whereas a commercial system will require one shot every second.
• Commercial Capacity: A full commercial reactor must generate roughly five times more energy than the demonstration plant to power necessary auxiliary equipment.
• Funding Structure: Supported by more than $1 billion raised through a milestone-based Series A round, the company has bypassed the requirement to raise capital every few years.
• Additional Uses: The site is also slated to host high-yield fusion experiments related to national security.

Why This Matters

Reaching net facility gain is one of the most difficult engineering barriers in commercializing fusion energy. Existing government research hubs, including the National Ignition Facility, are aging, and international competitors like China are developing comparable infrastructure. Achieving net gain at a facility scale would show that fusion devices can realistically supply net power rather than operating at a continuous energy deficit.

What to Watch Next

Pacific Fusion will proceed with the construction and assembly of the 156-module pulser system in Albuquerque, working toward its planned 2030 target for net facility gain. Observers will also track the broader commercial race against other well-funded fusion startups targeting mid-2030s grid connections, including Commonwealth Fusion Systems, Helion Energy, Proxima Fusion, and Inertia Enterprises.

Frequently Asked Questions

What is net facility gain?

Net facility gain refers to a benchmark where an entire fusion facility generates at least as much power as it consumes to operate, rather than just producing more energy within the core reaction itself.

How does Pacific Fusion trigger fusion reactions?

The company uses 156 pulser modules to deliver coordinated pulses of electricity. These pulses create a magnetic field that compresses a fuel target roughly the size of a pencil eraser until atomic fusion occurs.

When does Pacific Fusion expect to launch a commercial power plant?

The company is aiming to operate a full commercial power plant by the mid-2030s, following demonstration benchmarks targeted for 2030.
