Our Technology

Fusion Demonstration Program

A groundbreaking fusion demonstration program designed to commercialize our technology.

The Fusion Demo Program

Charting A Path For Breakeven.

We are accelerating our technological advancements to bring commercial fusion energy to the grid by the 2030s. General Fusion is constructing a cutting-edge Magnetized Target Fusion (MTF) fusion machine in Richmond, named Lawson Machine 26 or LM26. This machine is designed to achieve fusion conditions of over 100 million degrees Celsius by 2025, with a breakeven target set for 2026.

The plasma injector has already achieved the temperature and energy confinement times required by the new machine. LM26’s results will validate the company’s ability to compress magnetized plasmas in a repeatable manner and achieve fusion conditions at scale using General Fusion’s uniquely practical approach to fusion without requiring superconducting magnets or high-powered lasers.

This new machine will significantly de-risk the commercialization process, as it is designed to provide technical performance in the near term while shortening the technical path from our next near-commercial machine to a commercial plant.

Benefits of Magnetized Target Fusion Technology
General Fusion is pursuing the fastest, most practical path to bringing fusion energy to market using its Magnetized Target Fusion (MTF) technology. Here’s how our approach sidesteps the longstanding barriers to commercialization that others still face.

Man working

Plasma Injector

24 prototypes and over 200,000 plasma experiments helped us build the world’s largest and most powerful operational fusion plasma injector for LM26.

Compression System

With our scalable control systems, we’ve achieved the required timing precision with full-scale drivers to produce smooth, rapid, and symmetric compression of a liquid metal cavity.

Our Impact

Propelling Fusion Forward One Milestone After Another.

LM26 is a MTF demonstration that will seamlessly integrate our operational plasma injector with a simplified compression system. The plasma injector has already achieved the temperature and magnetic confinement times required by the new machine.

The data gathered from LM26 will be incorporated into the design of our planned near commercial machine in the UK. We are collaborating closely with our partners at the UKAEA as we advance LM26.
