LM26 is a key step in General Fusion’s milestone-driven pathway to commercialization. Designed to demonstrate that General Fusion’s MTF approach can achieve fusion conditions at a commercially relevant scale, LM26 is intended to de-risk the path to a practical fusion power plant.

Today, General Fusion has built and is operating LM26, a first-of-its-kind fusion demonstration machine. The machine is operational, forming and compressing plasmas as General Fusion executes a demonstration program to achieve transformative technical milestones.

General Fusion aims to complete the Lawson program by mid-2028 and believes this program positions the company to advance toward a first-of-a-kind plant producing energy around 2035. As LM26 progresses, General Fusion intends to move into its commercialization program: an engineering program to design and demonstrate key commercial systems and components, such as seals, valves, and heat exchange systems. This work supports the company’s goal of completing the final design of a first-of-a-kind plant and starting operations around 2035.
