Commercialization Path

OUR PATHWAY TO ECONOMICAL CARBON-FREE ENERGY IN THE NEXT DECADE

Today, General Fusion operates Lawson Machine 26 (LM26), a world‑first Magnetized Target Fusion (MTF) machine that was designed, built, and brought into operation in under two years. LM26 serves as the foundation for our program to achieve a series of transformative technical milestones that position us to deliver a first‑of‑a‑kind plant producing energy around 2035.

We aim to have the Lawson Program completed by mid‑2028. As we make progress with LM26, General Fusion intends to move into our commercialization program, an engineering program to design and demonstrate key commercial systems and components such as seals, valves, and heat‑exchange systems.

This leads to our goal of completing the final design of a first‑of‑a‑kind plant and beginning operations around 2035.

Lawson Program

This program involves a machine already in operation, LM26, that is designed to create fusion conditions at 50% power plant scale and validate our approach with industry‑changing milestones.

Validating & Demonstrating Commercial Systems

The goals of this program are to design and demonstrate key commercial systems and components, including seals and valves, liquid‑metal systems, and balance‑of‑plant and heat‑exchange systems.

Building & Operating a First-of-a-Kind Power Plant

A General Fusion FOAK plant will achieve engineering breakeven with an integrated commercial‑scale MTF machine, producing energy at commercial scale.

Today we have built and are operating a fusion demonstration machine that is the first of its kind, LM26. The machine is operational, forming and compressing plasmas, and we are now executing a demonstration program to achieve transformative technical milestones with our technology. First, we will heat to 1 keV, or 10 million degrees Celsius, then progress to 10 keV, or 100 million degrees. Ultimately, we aim to be the first company in the world to achieve the Lawson criterion—the combination of fusion parameters that can produce net fusion energy in the plasma. [For General Fusion’s approach, LM26 is designed to simultaneously demonstrate with hydrogen fuel the temperature, density, and energy confinement time that combined, represent the operating point of D-T plasma that satisfies the Lawson condition.]

Collaborators and Suppliers

Our Collaborators

General Fusion’s pathway is validated by an ecosystem of collaborators, suppliers, and potential early adopters who are working with us today.

We work with a wide array of technical and commercialization partners, including the UK Atomic Energy Authority and the U.S. Department of Energy on R&D and technology development; commercial collaborators such as Hatch on power‑plant engineering; Kyoto Fusioneering on fuel‑cycle and liquid‑metal systems; and a major automaker on piston‑compression technology development.

We are also engaged with more than a dozen potential end users who have signed agreements to join our Market Development Advisory Committee and work with us on our technology development and commercialization efforts.

General Fusion’s Magnetized Target Fusion

What sets General Fusion apart from the outset is our uniquely practical MTF approach with a liquid metal wall. Our technology was designed from the ground up with a power plant in mind.

By addressing key barriers such as material degradation, fuel production, energy capture, and cost, our approach offers a practical path without relying on expensive lasers or superconducting magnets.

The liquid metal wall:

Shields the fusion vessel from neutron activation.
Produces tritium fuel through neutron interactions with lithium.
Captures the energy produced by fusion efficiently. The liquid metal then circulates to a heat exchanger, producing steam to drive a turbine and generate clean electricity.
