Space-based solar power vs terrestrial solar-plus-storage: cost, capacity factor, and scalability compared
Compares space-based solar power (SBSP) delivering 99% capacity factor via microwave or laser beaming against terrestrial solar-plus-battery systems averaging 25–30% capacity factor. SBSP demo costs exceed $10B while utility-scale solar+storage falls below $40/MWh. Evaluates technology readiness, timeline to commercial viability, and grid integration requirements.
