In a significant advancement for concentrated solar power (CSP) technology, researchers have unveiled findings that could reshape the economic landscape of solar energy production. The study, led by Aabla Yahya from the National School of Arts and Trades at Moulay Ismail University in Morocco, focuses on optimizing the Noor I Solar Power Plant, one of the largest of its kind in the world, located in Ouarzazate.
Utilizing the System Advisor Model (SAM) developed by the National Renewable Energy Laboratory (NREL), the research meticulously evaluated various heat transfer fluids (HTFs) to determine their impact on both the efficiency and cost-effectiveness of the plant. Traditional thermal oils were compared with innovative silicone-based HTFs, including Helisol 5A and Helisol XLP, known for their superior thermal properties at elevated temperatures.
Yahya’s team discovered that employing these advanced HTFs could dramatically decrease the Levelized Cost of Energy (LCOE) to 25.72 cents per kilowatt-hour, a figure that positions the Noor I plant as a more competitive player in the renewable energy market. “The integration of silicone-based HTFs not only enhances thermal management but also paves the way for significant economic benefits,” Yahya stated. “Our findings suggest that optimizing these fluids can lead to a more sustainable and cost-effective energy production model.”
The research also highlighted the importance of optimizing thermal energy storage duration and HTF flow rates. The team found that a 3-hour storage period combined with an 8.1 kg/s flow rate struck the optimal balance between operational costs and energy output, further boosting annual energy production to an impressive 421 GWh.
The implications of this research extend beyond the Noor I plant. By demonstrating the potential for advanced HTFs to enhance CSP performance globally, this study offers a scalable framework that could inspire similar innovations in solar thermal power plants worldwide. As the energy sector increasingly shifts towards renewable sources, the findings could lead to broader adoption of CSP technologies, fostering a more sustainable energy future.
