VANCOUVER, British Columbia, January 10, 2022 (GLOBE NEWSWIRE) – General Fusion today announced that it has achieved several ambitious performance goals of a prototype system for its Fusion Demonstration Plant (FDP). The company’s prototype plasma compression, located in its laboratory in Vancouver, Canada, is used to demonstrate an essential element of its proprietary magnetized target fusion (MTF) technology. This milestone marks another milestone in General Fusion’s goal of creating a practical and commercially viable fusion power.

Commissioned in early 2021, the prototype machine causes a powerful, but precisely shaped, symmetrical collapse of a large liquid vortex cavity within tens of milliseconds. The forces involved in the large-scale FDP compression system will be immense, pushing the boundaries of materials science, fluid dynamics and mechanical design. Achieving this milestone with the prototype significantly reduces the engineering and technical risks for General Fusion’s FDP. It will use a collapsing liquid metal cavity to heat and compress plasma fuel under melting conditions of 100 million degrees Celsius.

The idea of ​​using a collapsing liquid metal cavity to create a fusion has been around for decades, but General Fusion has been able to bring in new enabling technologies such as high-speed digital control systems, the additive manufacturing and advanced composite materials to make this concept viable. and reduce the risks of its implementation in the FDP. Driving a fast, smooth, spherical-shaped collapse of a cavity created inside a rotating liquid has been a difficult engineering challenge that General Fusion has now demonstrated in this prototype machine. It is the pioneer of a larger prototype being built in 2022 to validate further improvements to various technical aspects of this technology.

“Net power generation is essential, but not really the ultimate goal of commercializing fusion energy, which is to build low-cost, carbon-free fusion power plants,” said Christofer Mowry, CEO of General Fusion. “Our unique technology, developed over two decades, solves the longstanding challenges of building practical fusion power plants for global energy markets struggling to move away from fossil fuels. The successful performance of this important prototype confirms that we are on the road to success. “

General Fusion’s unique MTF technology overcomes several key challenges in creating practical fusion energy. MTF will economically create fusion conditions, efficiently convert fusion energy into carbon-free electricity, protect the fusion machine from the combustion of fusion plasma, and produce enough fusion fuel for its own use. General Fusion’s prototype compression system validates one of the most critical parts of its MTF technology, as a mechanically collapsed liquid cavity is the cornerstone of MTF to overcome all of these challenges.
