Concentrating Solar Power (CSP) Discussed by SBI09 Feb 2012 • by Natalie Aster
The heat transfer fluid (HTF) flows from one receiver to the next, gaining heat at each step.
The fluid is collected and distributed through several manifolds. Alignment of the arrays is critical to minimize the already difficult piping. Part of the controls of the plant will include the valves that open and close the lines and control the movement of the HTF.
According to the report “Concentrating Solar Power (CSP)” by SBI, potential improvements in the HTF would reduce costs by increasing the operating range of the HTF. Currently the temperature limit to avoid thermal breakdown of the synthetic oil is typically below 750oF (400oC).
Mirrors consist of glass, polished metal or polymer films that are acquired in rolls and positioned on the mirrors on site. The mirrors must be able to withstand extreme temperature swings, wind, and dust storms. A high degree of reflectivity is necessary as well as a high degree of optical accuracy.

Brightsource, a CSP developer active in the southwest United States, was formed by some of the technical talent of the Israeli-based company Luz. Luz developed the PTT and implemented it in the original Solar Energy Generating Stations (SEGS) starting in the 1980's. The fact that Brightsource would now be endorsing CRS over PTT is very convincing.
Due to the reasons mentioned by BrightSource, SBI Energy believes the market will start to lean toward CRS technology. Additionally, as molten salt replaces oil as a heat transfer fluid,CRS will be even more favored as the piping is so much simpler. Significant heat tracing will be required but the increase in capacity as a result of longer hours of operation will offset the increased cost.
