National Institutes for Fusion Science

The National Institutes for Fusion Science (NIFS) in Japan is dedicated to researching nuclear fusion, a process that powers the sun and stars. Fusion involves combining lightweight atoms, like hydrogen, to release energy. NIFS develops advanced devices, such as the Large Helical Device (LHD), to study how to sustain and control fusion reactions safely on Earth. Success in this field could provide a nearly limitless, clean energy source. The institute collaborates internationally to advance fusion science and aims to make fusion power a practical, sustainable energy solution in the future.
