Experimental results for solar metallurgy, solar powder metallurgy of titanium, solar surface treatment of titanium and titanium welding are briefly reviewed. Most of them were performed at Plataforma Solar de Almeria Spain using solar furnaces SF5 and SF40 in gas/vacuum furnace. Generally, it was observed that the time to achieve required sample temperature is very short when concentrated solar power used. Thanks to use of renewable solar energy these technologies starts to be attractive for industrial production of titanium in Earth solar belt. It can be expected that the obtained results and approaches are similar also in Space. According to the obtained knowledge, the possible solutions/necessary changes for solar furnaces on Moon, Mars and in main asteroids belt are discussed.

Concentrated Solar Power

Aim & Scope: Renewable solar energy is one of the possible ways to decrease our impact on climate changes. Recent works worldwide starts to be focusing on applicability of Concentrated Solar Power in all aspects of our activities. A lot of work is done to use Concentrated Solar Power in industrial technologies instead of electrical energy during technological processes for example in desalination, plastic waste treatment, chemical and biological cleaning. Moreover, as indicate already published results of SFERA and SFERA 2 EU funded projects, Concentrated Solar Power can be also used directly in ore preheating, refinement and metallurgy of materials. In addition the solar energy can be used in materials science for sintering, reaction synthesis, heat treatment, surface treatment, composite preparation, welding, etc.. We kindly invite you to submit a manuscript(s) for this Special Issue. Full papers, communications, and reviews are all welcome.

Temperature Range

In the development of renewable energy sources, there has been a trend toward increasing and stabilising the power output of Concentrated Solar Power Plants (CSPPs) during times of reduced solar resource through the use of Thermal Energy Storage Devices (TESDs). This study investigates whether the use of a molten salt TESD decreases the efficiency of a parabolic trough CSPP due to additional system energy losses despite prolonging the operational time of the CSPP. A theoretical analysis of a simplified CSPP was made to determine if a TESD would impact the efficiency of the CSPP. This was followed up by a survey of currently active parabolic trough CSPPs both with and without molten salt TESDs. The theoretical analysis illustrated that a TESD would have no effect on the efficiency of a CSPP. However, the survey revealed that the use of a TESD improved the efficiency of a CSPP. The results of the study don't support the theoretical analysis or the hypothesis suggesting that a property has been overlooked. This property is most likely to be that generators tend to operate best within a certain temperature range, and in a CSPP the optimum temperature range cannot be maintained. This results in a generator being selected capable of operating for the longest period with the lowest amount of excess solar energy. When a TESD is implemented, the excess solar energy is stored for later use, prolonging the generator's running time and increasing the useable energy. The realisation of the ability of a TESD to increase the efficiency of a CSPP as well as extending its operating time shows a promising area of development in CSPP technology and increasing its application in electricity generation.

This paper analyzes the impacts of whole solar energy technologies on the economic situation of Afghanistan. Details and positive effects of solar mini-grids which are implemented through the Citizens’ Charter National Priority Program CCNPP in the rural areas of Afghanistan are given as samples of solar energy projects in Afghanistan. The result of this analysis then compared with the fossil fuel electricity that people use in the rural areas of Afghanistan based on the economic effects. The Levelized Cost of Energy (LCOE) for electricity generated through the diesel generator is estimated to be 29 ¢/kWh, which is 3.16 times higher than the cost of electricity produced via photovoltaic (PV) in 9.17 ¢/kWh. The potential for solar thermal as a recently boomed technology in the world is also studied with regard to the climate, economy, and security situation of Afghanistan. The country with 300 sunny days in a year has 1900-2000 kWh/m2 potential of producing electricity through the Concentrated Solar Power (CSP) technology. Using Multi-Criteria Decision Analysis (MCDA) the Parabolic Trough Collector (PTC) is selected as an optimal type of CSP in Afghanistan and a 3.5 MW PTC power plant is simulated via the System Advisor Model (SAM) software. The result of this simulation shows that this novel technology in Afghanistan needs more time and efforts to set as a secure approach of energy

The significance of sustainable power source has expanded because of environmental change and worldwide cautioning concerns because of its renewing quality. Solar energy is the focal point of numerous examinations due to modern industrial applications and small scale local applications in emerging nations. Solar energy is being bridled, either specifically utilizing photovoltaic or secondarily utilizing concentrated solar power. This study aims to design and fabricate a small scale concentrated solar power (CSP) plant using linear parabolic trough. Linear parabolic trough collector is used because of high efficiency and exceedingly prescribed kind of CSP. The scope of this study is to develop a CSP plant and also study the properties of various thermal fluids and expect the best transfer medium. The study done in this research is based on carrying out a detailed energy balance scheme for a linear parabolic trough collector while observing twenty-six vital design parameters, including the geometric measurements and material properties of concentrator and receiver pipe, thermal fluids properties, and operating conditions. Modeling of the system is carried out for different thermal fluids that are deemed viable for use. It was found that the results obtained from the fabricated parabolic trough CSP were used to verify the model and compare with the theoretical results. The conclusions deduced from this study will help design both small and large scale applications of linear parabolic troughs.

This study presents an outlook on the renewable energies in Iraq, and the potential for deploying concentrated solar power technologies to support power generation in Iraq. Solar energy has not been sufficiently utilized at present in Iraq. However, this energy source can play an important role in energy production in Iraq, as the global solar radiation ranging from 2000 kWh/m2 to a 2500 kWh/m2 annual daily average. In addition, the study presents the limited current solar energy activities in Iraq. The attempts of the Iraqi government to utilize solar energy are also presented. Two approaches for utilizing concentrated solar power have been proposed, to support existing thermal power generation, with the possibility of being implemented as standalone plants or being integrated with thermal power plants. However, the cost analysis has shown that for 50 kW concentrated solar power in Iraq, the cost is around 0.23 US cent/kWh without integration with energy storage. Additionally, notable obstacles and barriers bounding the utilization of solar energy are also discussed. Finally, this study proposes initiatives that can be adopted by the Iraqi government to support the use of renewable energy resources in general, and solar energy in particular.
