Controlled nuclear fusion, known as an “artificial sun,” related development work is being accelerated. The reporter learned from events related to the 2026 Nuclear Fusion Energy Conference and Nuclear Fusion Activity Week that breakthroughs have been made intensively in global fusion installations, and the industry as a whole is moving from theoretical experiments to the stage of engineering and industrialization. However, common problems such as plasma self-sustaining combustion, material service, and tritium fuel cycle are still “must-answer questions” throughout the engineering process. Facing development bottlenecks, upstream and downstream of the industrial chain have accelerated collaborative efforts, and various types of capital have continued to enter the market, enabling exploration of multiple differentiated fusion technology routes.
