A recent study suggests that while fusion power promises a zero-emissions, steady energy source, the cost reduction curve might not mirror the dramatic drops we've seen with solar or lithium-ion batteries. We often assume that every new tech follows a predictable downward cost trajectory, but fusion involves extreme engineering requirements—like superconducting magnets and tritium breeding—that don't necessarily scale linearly. If the capital expenditure for these plants remains astronomical, will they ever be competitive with a mix of renewables and advanced fission? Or are we risking billions in funding based on the assumption that 'it will get cheaper eventually' without a clear roadmap for how that happens?
