With increasing apprehensions over global warming and environmental issues, the need to develop renewable energy is becoming more critical to secure our future energy needs. Solar energy is the most abundant source of energy and is easily accessible. However, making efficient use of solar energy is not an easy task. Energy materials, especially in their micro and nanoscale, have an excellent potential for absorbing, transferring and storing solar energy when they are dispersed in an aqueous medium. The increased surface area to volume ratio of energy materials at nanoscale exhibits extraordinary characteristics. Various applications relevant to heat transfer, energy conversion, and storage have increasingly used nanoparticles due to their ability to absorb, store, and carry heat. However, successful deployment of materials in energy harvesting and storage applications must also consider some of the very fundamental challenges, including but not limited to sedimentation, entrainment, stability, and life of these potential energy materials. Additionally, there are novel applications of newly developed specialized materials in solar energy capture, transport and storage. This topic is to circumscribe all challenges, innovative applications and numerical studies in materials for energy capture, transfer, and storage to have a safe future in terms of solar energy utilization.

Thermal energy storage technologies are gaining attention nowadays for uninterrupted supply of solar power in off-sunshine hours. An indigenized solar phase change material (PCM) system was developed and performance evaluated in the current study to efficiently store solar thermal power using a latent heat storage approach, which can be utilized in any subsequent decentralized food processing application. A 2.5 m2 laying Scheffler reflector is used to precisely focus the incoming direct normal irradiance (DNI) on a casted aluminum heat receiver (220 mm diameter) from where this concentrated heat energy is absorbed and conducted to the PCM unit by the flow of thermal oil (Fragoltherm-32 thermo-oil). During the circulation around PCM pipes inside the PCM unit, thermal oil discharges heat energy to the PCM, which undergoes change of phase from solid to liquid. Computational fluid dynamics (CFD) analysis of the PCM unit were also performed according to the actual boundary conditions, which gave satisfactory results in terms of temperature and velocity distribution. With an average DNI of 781 W/m2, the highest temperature of the receiver surface during the trials was observed at about 155 C that produces thermal oil at 110°C inside the receiver and around 48°C of PCM in the PCM unit. The heat energy losses per unit time (W) due to the lack of reflectivity from the Scheffler reflector, out-of-focus radiations at the targeted area, absorptivity of heat receiver, piping system losses, and cylinder losses (in the form of conduction, convection, and radiations using 50 mm insulation thickness) were found to be 110 W (10 %), 99 W (9 %), 89 W (8 %), 128 W (12 %), 161 W (15 %), and 89 W (8 %), respectively. These findings of CFD analysis and mathematical modeling were also consistent with real-time data, which was logged through an online Control and Monitoring Interface portal. The final energy available to the PCM was 414W with an overall system efficiency of 38 %, which can be improved by decreasing thermal losses of the system and using other PCM materials.
