IAEA report maps global fusion energy progress and investment

The IAEA has published the World Fusion Outlook 2025 highlighting global developments, investment trends, and modelling of fusion deployment.

• Main announcement/action: The IAEA World Fusion Outlook 2025 documents that ITER remains the central international endeavour with 33 nations collaborating; global private investment has exceeded US $10 billion; the IAEA established the World Fusion Energy Group in 2024, and more than 160 fusion facilities are operational, under construction or planned. The report also includes MIT-conducted global modelling showing cost scenarios and projected electricity shares (see price details).
• Background and details: The Outlook outlines multiple parallel approaches (tokamaks, stellarators, laser/inertial confinement, magneto-inertial, mirror machines, field reversed configurations, pinches), highlights a special focus on HTS magnets, and cites projects integrating HTS such as SPARC and WHAM. The modelling uses capital cost scenarios of US $2.8K/kW (2050) and US $11.3K/kW, projecting fusion shares by 2100, and notes funding sources including sovereign wealth funds, major corporations and energy users.
