Pike Reseach reported on Dec 20, 2011 that, an estimated 70% decline in solar PV prices, and an easier permitting regime due to solar PV’s modularity, has contributed to the impression that CSP had missed its window of opportunity, and would be left behind.
Phase Change Materials (PCM) oscillate between solid and liquid phase within a certain temperature range (Mansfield). When the environment’s temperature is higher than that of the PCM, heat transfers from the surroundings to the material, which creates a cooling effect and changes PCM’s state from solid to liquid. When the environment’s temperature is lower than that of the PCM, heat transfers from the PCM to the surroundings, generating a warming effect and PCM changes back to its solid state.

CSP with Thermal Storage increases Power Value

Passive building with PCM and tools for analysis
Building energy consumption for it's temperature can be substantially reduced if solar energy is adequately utilized. Due to a strong need to reduce the total thermal energy requirement (both heating and cooling) in buildings, storage of thermal energy has gained prominence. The integration of phase change materials into building can provide a media to store the energy gain from solar radiation during the day and release the stored energy at night.
