“The picture has changed dramatically.”
Munich inventors want to build fusion reactors with barely used technology
Today 05.06.2023 | 11:05
Nuclear fusion aims to secure energy supplies for future generations. Munich startup Proxima Fusion is doing just that. The basis for the future reactor is one of the most impressive test facilities in the world.
In the search for renewable energy, one technology is particularly promising: nuclear fusion. Two hydrogen atoms fuse to form a helium atom. As a result of this process, some matter is converted into energy – not very little. Nuclear fusion generates about 90,000 kilowatt-hours of energy from just one gram of fuel. This roughly corresponds to the amount of energy of 11 tons of coal.
Munich startup Proxima Fusion plans The first commercial star reactor in the 1930s to construct. This design makes it possible to keep the plasma permanently in a burning state though several millionths of a degree Celsius. This is achieved by the complex arrangement of many strong magnetic coils. in press release The company announced that its latest fundraising round raised seven million euros from investors. Proxima Fusion is one Chapter of the Max Planck Institute. The research institute has created the world’s largest starburst facility in Greifswald, Mecklenburg-West. The Wendelstein 7-X has been in beta operation since 2015.
The complex structure provides advantages
Basically, there are two promising approaches to nuclear fusion reactors. On the other hand, there are tokamak reactors that, for example, in South Korea Run in test mode. On the other hand, there are the stellar reactors. Both types of systems differ in how they work. Tokamak reactors generate and discharge plasma. On the other hand, starbursts keep the plasma stable. This requires one Significantly more complex structure . The Wendelstein 7-X Test Facility contains 50 magnetic coils to stabilize the plasma. There are also another 20 magnetic coils, with which the plasma can be diversified and enhanced during the reaction.
Star reactors combine the two The highest and lowest temperatures in the entire solar system in the smallest space. The plasma temperature can reach 100 million degrees Celsius, while the surrounding magnetic coils are cooled to minus 270 degrees Celsius.

The rise to stardom gives reason for optimism
To date, most research institutions have relied on tokamak reactors. The development of star systems turned out to be much more complicated. “The experimental developments of W7-X and recent advances in stellar modeling have fundamentally changed the picture,” explains Francesco Sciortino, Co-Founder and CEO of Proxima Fusion. ” Stellarators can now fix major problems with tokamaks and extending its range by radically improving plasma stability and achieving high steady-state power. “If the Munich start-up can actually build functional stellar devices early next year, global energy problems can be solved.
