Review on the Economic Impacts of Solar Thermal Power Plants
Data availability: No data was used for the research described in the article.Copyright © 2023 The Author(s). A systematic literature review on the economic performance of solar thermal power plants including integrated solar combined cycle (ISCC) plants was conducted. A number of solar thermal technologies like parabolic trough (PT), solar tower (ST), linear Fresnel reflector (LFR) and solar dish (SD) were evaluated. The evaluation revealed that solar tower plants typically had the highest capital costs, followed by parabolic-trough and linear Fresnel plants. The results of the studies showed that at smaller capacities of 10–50 MW, PT plants achieved lower LCOE than ST plants, while at larger capacities of 100 MW and above, ST tend to have lower LCOE than PT. There was limited comparative studies on the economic performance of LFR and SD plants. Hence, future studies should focus on the economic impact of different solar thermal technologies including LFR and SD of various capacities using homogeneous modelling conditions. The economic performance of direct steam generation (DSG)-ISCC plants was compared to ISCC, combined cycle gas turbine (CCGT) and conventional solar thermal plants and the results showed that DSG-ISCC plants achieved the lowest LCOE values. Studies also showed that in general, hybrid plants achieved lower LCOE than standalone solar thermal plants. LCOE and capital costs were the dominant financial metrics used in the literature, with very few studies using total life cycle cost, revenues, payback time and internal rate of return. Future studies should include these metrics in order to provide a comprehensive financial assessment of solar thermal power plants, enabling their economic performance to be compared with other renewable and non-renewable energy systems.EU Horizon 2020 research and innovation programme, Application of Solar Thermal processes in Industrial Processes (ASTEP), under grant agreement No 884411

Environmental impacts of solar thermal power plants used in industrial supply chains
Data availability: No data was used for the research described in the article.Copyright © 2023 The Author(s). A systematic literature review was conducted to investigate the environmental impact of solar thermal power plants in the industrial supply chains. A number of different solar thermal power collectors like parabolic trough (PT), linear Fresnel (LFR), solar dish (SD) and solar towers (ST) were considered and analysed. The first observation was that PT collectors generate the lowest level of Green House Gas (GHG) emissions, followed by LFR, DT and SD plants. There was a lack of studies dealing with the GHG emissions of LFR and SD plants, which demonstrated a need of conducting more studies to gain better understanding of their environmental performances. The second observation was that different environmental assessment software tools used for analysing the environmental impact showed conflicting results because of the different approaches used in the characterization factors management in each software. Those software tools include: SimaPro, Gabi, System Advisor Model (SAM), Umberto and Thermoflex + PEACE. The standardization of environmental software tools and life cycle impact assessment methods is required to prevent discrepancies in life cycle assessment results. The third observation was the need for integrated environmental and economic assessments to provide a comprehensive evaluation of the solar thermal plants as it will enable investors, policy-makers and researchers to make informed decisions about the environmental and economic impacts of those plants.EU Horizon 2020 research and innovation programme, Application of Solar Thermal processes in Industrial Processes (ASTEP), under grant agreement No 884411
