Nuclear Fusion Explained Clearly and Vividly: The New acatech HORIZONS Are Here

Munich, 21 September 2026

Once considered science fiction, nuclear fusion is now being intensively researched and developed in Germany and many other countries as a potentially viable energy source for the future. As great as its potential is, the physical principles of nuclear fusion and its technological application are highly complex. The new acatech HORIZONS on nuclear fusion provide an accessible introduction and support an informed debate: science-based and accessible, vivid and balanced. 

For a long time, nuclear fusion was regarded as a technology of the distant future. It has now become a key focus of innovation policy strategies, is attracting enormous investment worldwide and is driving a global competition for scientific expertise and technological leadership. Germany has set itself the goal of building the world’s first fusion power plant. acatech is advising on the development of a Research and Innovation Roadmap for Nuclear Fusion.

But what are the physical principles of nuclear fusion? How does it differ from nuclear fission? Why does nuclear fusion require such extreme temperatures? And how can fusion energy be integrated into renewable energy systems? The new acatech HORIZONS answer these questions with scientifically sound content in accessible language, accompanied by vivid infographics.

For the first time, acatech HORIZONS are also being published as an interactive website. Alongside the printed brochure, the website offers videos, animations, in-depth information and a fusion quiz. The HORIZONS are aimed at anyone looking for an in-depth yet accessible and entertaining introduction to the fascinating and complex world of nuclear fusion. They are a valuable resource for anyone looking for engaging, scientifically sound materials developed in collaboration with leading fusion researchers. The explanatory graphics from acatech HORIZONS: Nuclear Fusion are available to download free of charge for use in presentations, at events and on social media.
