“…The effect of SM on LCOE has been simulated for molten salt linear Fresnel plant (MSLFP) with solar field only, that is, without BS and storage thermal energy, using the wet cooling system because it is the lower than dry cooling in CSP plant as mentioned in different studies . Furthermore, the value of SM is varied between 1 and 3 with a step equal to 0.1, then LCOE has been plotted in function of SM.…”

In the present work, the design-environmental and economic (D2E) comparative study of seven different configurations of Linear Fresnel solar thermal power plants using two-generation modes (direct and indirect steam generation) with nine various working fluids, with and without integrated thermal energy storage or/and backup fuel system is presented, with minimum levelized cost of energy (LCOE) as objective.This study is based on a power plant of capacity of 50 MW. A sensitivity analysis is developed to optimize the solar multiple of the solar field, Fossil fuel fraction of backup system (BS), and TES hours capacity, using System Advisor Model software.The results show that the wrong choice of plant's components and inexact performance optimization lead to the increasing cost of electricity generated due to operating costs and additional investments. The BS was the most significant contributor to greenhouse gas emissions at all sites, contributing over 90% of total emissions, due to its relative contribution (95 kg/MWh). Finally, the combination of the storage and BSs in molten salt mode makes it more competitive under Algerian climates, which confirms that molten salt linear Fresnel solar plant with 25% of a BS and 6 hr of the storage system is the best and optimum solution.

It reinforced what advocates have long argued: That a rapid and global transition to RE technologies offers a realistic means to achieve sustainable development and avoid catastrophic climate change. 1 Moreover, RE technologies can help countries meet their policy goals for secure, reliable and affordable energy, electricity access for all, reduced price volatility, and the promotion of social and economic development. 2 In Algeria, With the development of economy and the rapidly increasing of electricity demand, environmental issues, and fossil energy shortage are becoming increasingly serious, which allows the government to use other sources as REs. Therefore, the challenge facing governments has shifted from identifying what needs to be done and how best to achieve it.Different questions can be given for the electricity system by variable renewable, but the principle is the same: A mix of technologies in a range of locations will be required to meet the demand that varies

“…By considering four factors (i.e., energy, environment, exergy, and economy), the study concluded that the presented optimization analysis can be further improved by taking into consideration influential factors such as solar radiation, cooling system technology, and key plant design parameters. Based on a 50 MW capacity CSP power plant intended to be implemented in Hassi R'mel City, in the south of Algeria, Mihoub et al ( 2017 ) proposed a procedure for identifying the best configuration as well as an ideal design to adopt for the future solar thermal power plants setting maximization of their annual power generation and minimization of their LCOE as the methodological objectives.…”

“…Given the fact that parabolic trough systems, with their dominance and ability to generate electricity whether as stand-alone or in hybrid systems at the lowest LCOE and with low technical and economic risks, have been widely utilized over the past decades worldwide, and while several studies such as (Abbas et al 2013a , b ; Boukelia et al 2015 ; Mihoub et al 2017 ; Ikhlef and Larbi 2020 ) have attempted investigate the possibility of implementing parabolic trough systems in Algeria to ensure a sustainable energy transition, to the knowledge of the authors no study has so far taken into consideration prominent factors such as solar radiation, cooling system technology used, seasonal variations, and other key design parameters in their investigations. Also, these studies in the literature did not consider the actual electricity load profile of the targeted location investigated for the installation of the parabolic trough power plant.…”

Algeria’s energy demands are tremendously growing, and on the African continent it ranks among the countries with the highest energy consumption. To counter its growing energy demand, the country is progressively adopting renewable energy technologies, although conventional energy technologies still play a central role in its electricity production. The huge solar energy potential in Algeria can be exploited and utilized to meet the country’s growing energy demand with minimal greenhouse gas production. Given that concentrating solar power is viewed as one of the most promising alternatives in the field of solar energy utilization, this study investigates the viability of a 100 MW parabolic trough-based power plant at Tamanrasset, Algeria. The plant was simulated in the System Advisor Model software considering the actual electricity load profile of the targeted location and implementing two different condenser types: evaporative and air-cooled. By comparing the plant’s electricity production to the city’s real load, the plant was in position of supplying about 78% and 60% of the city’s electricity demand during the winter and summer seasons, respectively. The results show that implementation of such CSP plants could play an important role in meeting the energy demand as well as mitigating climate change through greenhouse emissions avoided in electricity generation process.

“…Solar energy is an important renewable energy source that is expected to play a significant role in the future energy supply mix. Concentrated solar power (CSP) technology is an important option for acquiring solar energy which draws increasing attention during past several decades [1,2]. It is internationally believed that for every 1 percentage point increase in the annual average power generation efficiency of solar thermal power generation systems, the average power generation cost will be reduced by 5% to 8%.…”

Effect of Laser Shock Processing and Aluminizing on Microstructure and High-Temperature Creep Properties of 321 Stainless Steel for Solar Thermal Power Generation

The aluminized layer of 321 stainless steel was treated by laser shock processing (LSP). The effects of constituent distribution and microstructure change of the aluminized layer in 321 stainless steel on creep performance at high temperature were investigated. SEM and EDS results reveal that aluminized coating is mainly composed of an Al 2 O 3 outer layer, the transition layer of the Fe-Al phase, and the diffusion layer. Additionally, LSP conducted on coating surface not only improves the density of the layer structure, resulting in an increment on the bonding strength of both infiltration layer and substrate, but also leaves higher residual compressive stress in the aluminized layer which improves its creep life effectively. Experimental results indicate that the microhardness of the laser-shocked region is improved strongly by the refined grains and the reconstruction of microstructures. Meanwhile, the roughness and microhardness of aluminized steel are found to increase with the laser impact times. On the other hand, the intermetallic layers, whose microstructure is stable enough to inhibit crack initiation, reinforce strength greatly. The anticreep life of aluminized sample with three times LSP was increased by 232.1% as compared to aluminized steel, which could attribute to the increased dislocation density in the peened sample as well as the decrease of creep voids in size and density.
