Concentrated Solar Power (CSP) is a green, efficient and stable generation of power with low operating cost. In comparison with Photovoltaic (PV) Power, the CO2 discharge during the full life circle of CSP plants is only 13~19g/kWh, and its incident photon-to-electron conversion efficiency (IPCE) can be as high as 15%~25%. Unlike Photovoltaic Power, the most prominent advantage of CSP is the solar power that is absorbed can be stored during the day time and can be released in the night to continue generating power.


In late August of 2017, a delegation headed by Mr. Kang Jianbin, Vice President of Hualu, made a week-long visit to Denglingha Prefecture, located in north-east brink of Tarim Basin in China’s north-west Qinghai Province, where China’s first 10 MW CSP is built as a demonstration plant. The CSP plant consists of two towers, with water as heat storage media in the first tower and molten salt in the second tower. Acceptance test organized by the central government authorities in early 2017 reveals that the CSP plant built using the technology developed by Supcon meets its design parameters and the technology is proven for commercial applications. Success of the demon plant puts it as the FIRST of its kind in China, and the THIRD in the world. As a follow-on development, a 50 MW CSP is being constructed adjacent to the demon plant. The commercial CSP plant employs molten salt for heat storage,  enabling it to generate power around the clock.

CSP has such a promising future that there is a good likelihood that it will replace fossil-fuel fired power plants sooner or later, when its per watt capital cost is reduced with large scale applications of the technology in the world.
