Materials for fusion reactors: Containing a star on Earth Sandy (Alexander) Knowles, the Associate Professor in Nuclear Materials at the University of Birmingham, explores experimental metallurgy research and its structural materials to withstand the extreme temperatures inside nuclear fusion reactors. Fusion Energy provides near limitless energy without generating carbon emissions, or long-live radioactive waste. This entails it can be used for its energy density and small land usage, making it capable of providing stable base-load electricity, making it an ideal solution to our present energy challenges. Companies globally are currently seeking new approaches to fusion energy with development and fast deployment timelines, ultimately seeking to bring fusion to market sooner, potentially before 2040. Representing a ‘moonshot' innovation – with equivalence to the moon landing in terms of the pace and scale of developments needed, this collaborative societal grand challenge of fusion energy is a new opportunity for science, technology, engineering and mathematics (STEM), at all levels. |
