The superconductivity research group of the University of Twente (UT) has made a technological breakthrough crucial to the success of nuclear fusion reactors, allowing for clean, inexhaustible energy generation based on the workings of the stars in our galaxy.

The crux of the new development is a highly ingenious and robust superconducting cable system. This makes for a remarkably strong magnetic field that controls the very hot, energy-generating plasma in the reactor core, laying the foundation for nuclear fusion. The new cables are far less susceptible to heating due to a clever way of interweaving, which allows for a significant increase in the possibilities to control the plasma. Moreover, in combination with an earlier UT invention, the cables are able to withstand the immense forces inside the reactor for a very long time. The increased working life of the superconductors and the improved control of the plasma will soon make nuclear fusion energy more reliable: the magnet coils take up one third of the costs of a nuclear fusion power station. The longer their working life, the cheaper the energy will be. The research is a project within the context of the Green Energy Initiative of the University of Twente.
