2025 marks the year nuclear fusion transitions from experimental research to measurable industrial deployment. Driven by AI, regulatory innovation, and strategic hubs across North America, Europe, China, and Japan, this wrap-up highlights key milestones, market acceleration, and the outlook for grid-connected pilot plants by 2028–2030.

Germany is making a bold €2 billion bet on fusion, shifting the conversation from research to commercialization. With lighter regulation, dual-tech pathways, and strong public–private backing, Berlin is positioning itself to lead the global fusion race. The question now is not if fusion will happen—but who will deploy it first.
