Nuclear fusion is a process in which two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy. The reaction commonly uses hydrogen isotopes such as deuterium and tritium, which can generate energy when heated to extremely high temperatures and converted into plasma. Fusion is considered an advanced clean-energy technology because it has the potential to provide large-scale power generation with very low greenhouse gas emissions and without the long-lived radioactive waste typically associated with conventional nuclear fission.
The global nuclear fusion market encompasses the development, demonstration, and future commercialization of fusion energy systems, as well as supporting technologies, fuel cycles, components, engineering services, and research infrastructure. The market covers companies and institutions working on plasma confinement, superconducting magnets, laser-based fusion systems, tritium handling, fusion fuels, reactor materials, power plant design, diagnostics, and control systems. Although the market is still at an early commercial stage, it is gaining momentum due to rising clean-energy demand, government funding, private investment, and technological progress in magnetic confinement, inertial confinement, magneto-inertial fusion, alternative magnetic systems, and pulsed fusion concepts.
