‘Fusion is and always will be 30 years away!’ ‘There is no progress in nuclear fusion research!’ ‘Why don’t we just use our already working fusion reactor and simply use solar panels?’
Statements like these are not unusual when it comes to nuclear fusion, but let’s explore the reality.
Is there really no progress in nuclear fusion research? Are we never going to unlock nuclear fusion’s full potential?
To answer these questions and more, we’re excited to invite you to ‘EUROfusion Engage’, a new series where we delve into the world of nuclear fusion research. Here, we are going to show you a weekly ‘image of the week’, giving you insights into current nuclear fusion activities and ongoing research. The aim is to create a collaborative environment with room to share fresh perspectives, discuss current challenges, and together, explore potential solutions. Whether you’re taking your first step into nuclear fusion or you’re already passionate about energy innovation, your voice is welcome here. Let’s learn, discuss, and contribute to shaping a sustainable energy future!
Our first image gives an insight into challenges related to materials. Have you ever wondered what happens when the perfect material for a project doesn’t exist?
You could dig through the whole periodic table or hit the books, but sometimes, even that’s not enough. The only available option here: Do Research. Imagine new methods. Improve manufacturing techniques. Explore new material combinations or designs.
Scanning electron microscope (SEM) image of a tungsten fiber reinforced tungsten composite manufactured via Chemical Vapor Deposition (CVD), Alexander Lau, Forschungszentrum Jülich (FZJ). Image was obtained with an SEM Carl Zeiss LEODSM982.
This image showcases such an approach, using tungsten fibers with specific structures, reinforcing a tungsten matrix. This kind of material utilizes the same reinforcing mechanisms as reinforced concrete, with the aim to increase the toughness and endurance of tungsten. Tungsten is vital in the plasma-facing wall of fusion machines due to its high melting point and unique properties. Upscaling lab-scale solutions also demands time and resources. Going from A to B, like building a nuclear fusion reactor, is like climbing a hill with numerous milestones. It necessitates new tools, materials, and solutions for unforeseen challenges.

“I am particularly fond of this image because it represents my first-ever tested sample within the scope of my project. It’s a constant reminder of the unique design of our composites and its broad application potential. The challenge of working in extreme environments often leads to groundbreaking technological discoveries that can benefit numerous fields. For me, being a part of this innovative and dynamic area of research is not just professionally rewarding, but also a personal and fulfilling journey.”
