Abstract
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.
