“…Among the solar thermal technologies, parabolic troughs (PTC) and linear Fresnel lenses (LFC) are popular for generating electricity in addition to the molten salt tower technology. 24 The solar concentration ratios in PTC and LFC are to a maximum of 40 to 45 compared to up to 1500 in the case of the STT. The corresponding temperatures that can be achieved at the receiver will also be lower in the PTC and LFC.…”

India has incorporated renewable energy sources like solar and wind in its energy mix in order to achieve its ambitious plan to set up 175 GW of renewable energy by 2022 to reduce the emissions of greenhouse gases. Among the solar technologies for power generation, solar photovoltaic (SPV) is considered and large SPV parks are deployed around the country. Some of the drawbacks of deploying large-scale SPV parks are discussed in the manuscript. Because of the intermittency of SPV and wind, there is a backup resource of fossil fuel fired thermal plants that are ramped up or down to meet the electricity demand in the grid, especially the peak demand. The manuscript proposes that India has to consider solar thermal technology that can be ramped up and down, namely, the molten-salt solar tower technology (STT). Based on the direct solar irradiance data there are about 6000 sq. km of land with 7.5 to 8.0 kWh/m 2 /day and about 12 000 sq. km with 7.0 to 7.5 kWh/m 2 /day where such STT plants can be set up. Cost analysis demonstrates that the capital cost of STT plant is roughly ₹ 389 million per MW. This is quite competitive compared to the nuclear and coal thermal technologies because these technologies have high operational costs.

“…A mathematical model of solar plants can be created using various techniques, and a nonlinear system of partial differential equations can accurately predict design features, operational parameters, and performance. 14,15 Concentrated solar power (CSP) or concentrated solar energy (CSE) alternatives have been developed to efficiently produce renewable thermal energy 16,17 and provide thermal energy to industrial processes such as a textile factory in Spain, 18 a pasteurization process in Austria, 19 a sea-water desalination plant in India, 20 a soft drinks factory in Cyprus. 8 Although CSP/CSE plants have been built in various countries, they are considered expensive to install in remote areas or in countries where they have not been previously implemented, such as developing and least-developed countries.…”

This study analyzes the integration of a solar thermal plant for indirect steam generation in a typical industrial process with thermal energy requirements. Solar irradiation is computed using a validated predictive model in Santa Fe province, Argentina. Three configurations are proposed, consisting of parabolic trough collectors and thermal storage tanks. Performance indicators, such as generated energy, resulting solar fraction (the fraction of the industrial process' thermal requirements met by solar energy), and necessary solar field area, are evaluated for each configuration. A specific energy map is generated, showing the solar generation potential at each location. For required solar fractions of 20%‐25%, incorporating a thermal storage system does not provide any benefits as the solar plant does not produce enough energy to contribute to the industrial process during winter months. For required solar fractions of 30%‐35%, the resulting solar fraction can be increased to 42%‐45% with additional capture area and thermal storage capacity. For required solar fractions of 37%‐40%, the thermal storage improves the efficiency of the solar plant, resulting in a solar fraction of 50%‐60%, allowing the industrial process to receive energy for at least 6 h a day throughout the year. It is concluded that these configurations are suitable for providing a portion of the industrial process' thermal requirements.

In this study, “Concentrated Solar Energy (CSE)” is applied for soldering and is named as the “Concentrated Solar Energy Soldering (CSES) technique.” Lead-free solders are used for comparing novel CSES technique solder joints with CSI (Conventional Soldering Iron) solder joints. Tensile strength, bending/flexural strength, microhardness, electrical resistivity, fractography, optical microstructures, SEM microstructures, and EDS analysis were used to compare CSES solder joints with CSI solder joints. The salt spray test (SST) was used for corrosion analysis of CSES and CSI solder joints. Experimental results reveal that the tensile response, bending strength, and microhardness of the CSES solder joints were almost equal to those of the CSI solder joints. It was observed that after corrosion, the tensile strength, bending strength, and microhardness for CSES and CSI solder joints reduced. CSES solder joints were found to be slightly better than CSI solder joints for electrical resistivity. Electrical resistivity for all the cases studied was found to increase slightly after corrosion. Interfacial integrity and effect of corrosion were clearly observed on CSES and CSI solder joint microstructures. The intermetallic compounds (IMC) formed in case of CSES solder joints were found to be having slightly less thickness than that of CSI solder joints. The results demonstrate CSES technique as a green technology and a potential substitute to the CSI method.
