LM26
Large-Scale Demonstration in Operation
Lawson Machine 26 (LM26) is General Fusion’s large-scale MTF demonstration machine, built and operating in Vancouver.
Designed, built, and assembled in less than 2 years, the machine is designed to advance through key technical milestones—including 1 keV, 10 keV, and the Lawson criterion—that define progress toward commercial fusion. Each milestone builds on prior results and is intended to validate the performance required for a commercial system.
For General Fusion’s approach, achieving the Lawson Criterion means simultaneously demonstrating, using hydrogen fuel, the temperature, density, and energy confinement time that together correspond to the operating conditions required for D-T plasma to achieve fusion power in excess of the rate of heat loss.
From Demonstration to Commercial Systems
As the LM26 program progresses, General Fusion expects to transition into its commercialization program, potentially as early as 2027, by advancing our engineering efforts to design and demonstrate key commercial systems and components, including seals, valves, and heat exchange systems. Completion of this commercial systems demonstration program is expected to support final plant design and the construction of a first-of-a-kind facility, with initial operations targeted around 2035. This potential pathway is enabled by General Fusion’s engineering-driven approach and the commercialization advantages of MTF.
Commercial system validation will include:
- High repetition rate for key components and systems
- Key liquid metal systems and components
- Key balance of plant systems
These steps support the development of a first-of-a-kind fusion plant and the broader transition to commercial deployment.

First-of-a-Kind Plant
General Fusion is targeting operations of our first-of-a-kind plant by approximately 2035, aiming to achieve engineering breakeven with an integrated, practical commercial-scale MTF machine.
Broad Power and Industrial Applications
General Fusion’s potential customers and early adopters include electric utilities, independent power producers, state-owned enterprises, energy developers, and industrial companies seeking firm, low-carbon power.
Target applications include:
- Grid-scale electricity generation
- Industrial heat and steam
- Power supply for artificial intelligence
- Data centers
- Mission-critical operations, including defense and remote installations.
Regulatory & Siting Simplification
Fusion power systems are also expected to face reduced regulatory and siting complexity compared to conventional nuclear fission facilities, supporting greater flexibility in project development. The expected radiation profile for a fusion power plant is also significantly improved compared to a fission plant, as fusion power does not generate either high-level or long-lived radioactive waste requiring permanent geological disposal, unlike nuclear fission and SMR technologies.
Dependable, Compact Baseload Power
Unlike wind and solar, fusion is designed to provide continuous, dispatchable baseload electricity that is not dependent on weather or time-of-day conditions. Fusion power facilities are also expected to require significantly less land per unit of electricity produced than many renewable generation sources, helping reduce land-use constraints, transmission requirements, and siting challenges.
