CSP-Storage-Hydrogen Integrated Solution

CSP Heat Collection, Thermal Storage, Power & Hydrogen

Overview

The CSP-Storage-Hydrogen system uses concentrated solar power as a clean heat source. Parabolic trough or Fresnel collectors capture solar thermal energy to heat thermal oil or molten salt for thermal storage, enabling 24/7 continuous and stable heat and steam output. The system can directly supply heat (40–50% efficiency) or drive turbine generators for power generation (22–25% efficiency), while also producing stable green hydrogen through electrolysis. This achieves multi-energy coupling of solar, heat, power, and hydrogen. Compared to traditional CSP plants, adding hydrogen production further improves economic viability and operational flexibility. The system is ideally suited for high-altitude cold regions, remote areas, large-scale national energy projects, and industrial heat applications.
