General Fusion Group Ltd.

About

General Fusion, founded in 2002 by Canadian physicist Dr. Michel Laberge, is dedicated to developing a practical path to fusion energy. The company focuses on building real systems designed to deliver clean, reliable fusion power at scale, advancing fusion technology through experimental systems and large-scale machines over more than two decades.

["Lawson Machine 26 (LM26) is General Fusion’s large-scale MTF demonstration machine. Built, commissioned, and operating in under two years, LM26 is designed to compress plasmas to achieve industry-recognized milestones:\n\n- **1 keV — 10 million degrees Celsius**\n- **10 keV — 100 million degrees Celsius**\n- **Achieving 100% Lawson Criterion1  — the combination of fusion parameters that can produce net fusion energy in the plasma**\n\n1. For General Fusion’s approach, achieving the Lawson Criterion means simultaneously demonstrating, using hydrogen fuel, the temperature, density and energy confinement time which combined correspond to operating conditions required for D-T plasma to achieve fusion power in excess of the rate of heat loss.\n\nLM26 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.\n\nToday, 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.\n\nGeneral Fusion aims to complete the Lawson program in 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.\n\nLM26 has progressed from construction to operation and is advancing through a defined sequence of technical milestones.\n\nAchieved\n\nLM26 Assembly Completion (December 2024) from General Fusion on Vimeo\n\nFebruary 2025\n\nFirst plasma\n\nApril 2025\n\nFirst plasma compression\n\nAdvancing Toward\n\n1 keV (10 million degrees Celsius)\n\n10 keV (100 million degrees Celsius)\n\n100% Lawson criterion"]
