Large-scale renewable energy sources with tremendous potential include concentrated solar power, which is currently attracting attention due to its use and room for growth. Due to their higher efficiency when compared to photovoltaic, parabolic trough solar collectors (PTSCs) in particular are becoming more and more popular. This work aims to assess the performance of a planned 24-m-long PTSC model in a 10m 3 /day solar MED water desalination plant with a 2.2m 3 storage tank. Oil served as the working fluid in a glass heat-collection element. Based on seasonal data for average intake and outflow temperatures and surface temperatures for Cairo's climatic conditions, the suggested model's authentication is supported.

“…Typical PCMs for low temperature applications are organic compounds with very low thermal conductivities and heat transfer rates. A number of approaches to improve the thermal conductivity of PCMs have been investigated, including the addition of highly thermally conductive phases such as graphite [7,8]. Further, encapsulation of organic PCMs into inorganic shells with higher thermal conductivity was found to increase the heat transfer rates [9,10].…”

“…Addition of micro and nano-scale EPCM to a HTF allows for good dispersion stability, creates minimal obstructions to the flow, and offers dual property advantage such as increased specific heat due to the latent heat of PCM [7,12] as well as enhanced thermal conductivity [12,13].…”

Use of encapsulated zinc particles in a eutectic chloride salt to enhance thermal energy storage capacity for concentrated solar power

Concentrated Solar Power (CSP) is considered as a viable large-scale renewable energy source to produce electricity. However, current costs to produce electricity from CSP are not cost competitive as compared to the traditional energy generation technologies based on fossil fuels and nuclear. It is envisioned that development of high efficiency and high heat capacity thermal storage fluids will increase system efficiency, reduce structural storage volume, and hence, contribute to reducing costs. Particularly, with respect to CSP, current high temperature energy storage fluids, such as molten salts, are relatively limited in terms of their thermal energy storage capacity and thermal conductivity. The current work explores possibility of boosting the thermal storage capacity of molten salts through latent heat of added phase change materials. We studied the advantage of adding coated Zn micron-sized particles to alkali chloride salt eutectic for enhanced thermal energy storage. Zinc particles (0.6 µm and 5 µm) obtained from commercial source were coated with an organo-phosphorus shell to improve chemical stability and to prevent individual particles from coalescing with one another during melt/freeze cycles. Thermal cycling tests (200 melt/freeze cycles) showed that coated Zn particles have good thermal stability and are chemically inert to alkali chloride salt eutectic in both N 2 and in air atmospheres. Elemental mapping of the cross-sectional view of coated Zn particles from the composite after thermal cycles showed no signs of oxidation, agglomeration or other type of particle degradation. The measured enhancement in volumetric thermal storage capacity of the composite with just ~10 vol% of coated Zn particles over the base chloride salt eutectic varies from 15% to 34% depending on cycling temperature range (∆T = 50°C-100°C).
