Solar Dish Collectors for Hydrogen Production: A Review

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Solar‐driven hydrogen production stands at the nexus of the global transition toward net‐zero energy systems. This review surveys the role of solar dish collectors (SDCs) as high‐flux concentrators that can directly or indirectly split water, positioning hydrogen as a long‐duration, carbon‐free energy carrier.
