New research published in Nature Energy suggests that fusion power may not become significantly cheaper over time, contrary to optimistic projections. The study estimates fusion's "experience rate"—the cost reduction per capacity doubling—to be between 2% and 8%, much lower than the 8% to 20% often assumed in current models. This slower cost decline, driven by fusion's complexity and size, could mean that electricity from fusion plants remains expensive for a considerable period. The findings prompt questions about current investment levels in fusion, especially concerning its role in decarbonization efforts. AI
