The Fusion Expert Group (FEG) supports the development of an EU Fusion Strategy, expected to be published in view of the proposal of the Euratom Research & Training Programme for 2028–2032. This FEG Opinion Paper envisions fusion as a sustainable energy source and provides recommendations to accelerate its commercialisation. It identifies five key pillars that leverage research and ITER outcomes, foster a competitive industrial ecosystem, develop a skilled workforce, and drive innovation. The report emphasises the need for regulatory harmonisation, international collaboration, and an effective EU-level decision-making process in order to position fusion as a cornerstone of Europe’s energy future.
