Recently, amid extreme cold weather reaching -15°C in Delingha, Qinghai, exciting news came from CGN's Solar Thermal Test Base: its self-developed large-aperture molten salt trough collector system technology has achieved a key breakthrough, with the outlet molten salt temperature of the loop reaching 550°C, marking the complete success of the first thermal collection test. This achievement signifies that China's core concentrated solar power (CSP) technologies are now fully independent and controllable, significantly driving down the levelized cost of electricity (LCOE), and injecting strong momentum into the closed-loop industrial chain of "salt lake—molten salt—solar thermal" and the construction of Delingha as China's "Solar Thermal Capital."
According to reports, CGN Solar Thermal Technology Company currently maintains professional R&D teams specializing in system integration, operational control, solar collection, and thermal energy storage technologies. Since 2025, the company's independently developed domestic-first macro site selection platform software for CSP has provided increasingly precise and efficient site selection consulting services for projects including the Tibet Wumatang Trough CSP Integrated Project. Leveraging the Strategic Special Project for Trough CSP Power Generation (Phase I), CGN Solar Thermal Technology Company has achieved fruitful innovation results throughout 2025: completing the design, development, assembly and installation of a new-generation large-aperture molten salt trough collector; successfully developing critical supporting equipment including local control systems, molten salt flexible connection components, and mirror surface inspection systems; and establishing a large-aperture molten salt trough pilot platform—all laying a solid foundation for subsequent large-scale application and continued cost reduction.
