Enhancing renewable energy systems using loop heat pipes: A case research on solar thermal applications

The growing global demand for clean energy solutions underscores the need for renewable technologies that address the limitations of traditional systems. Solar thermal systems, integral to decarbonization efforts, face challenges such as thermal inefficiencies, high heat losses, and performance fluctuations under varying environmental conditions. This research proposes the integration of Loop Heat Pipes to enhance solar thermal system efficiency and reliability. The model systematically investigates Loop Heat Pipes integration across different operating conditions, emphasizing improved thermal performance, reduced energy losses, and adaptability to diverse climates. Unlike previous studies that rely on theoretical analyses and isolated cases, this research introduces innovative configurations, incorporating advanced heat transfer models and experimental validation. Two case studies assess Loop Heat Pipes integration: a residential solar water heating system in Phoenix, Arizona, and a utility-scale solar thermal power plant in Rajasthan, India. Results indicate that residential systems achieved a 41.7% thermal efficiency improvement and a 30% increase in peak water temperature. Utility-scale systems demonstrated a 75% reduction in thermal losses, an 18.75% increase in energy output, and a 20% decrease in the levelized cost of energy. These enhancements confirm Loop Heat Pipes technology's potential to optimize solar thermal performance and sustainability. The research validates system efficacy through theoretical models and experimental setups, ensuring real-world applicability. Findings highlight Loop Heat Pipes integration as a transformative approach for minimizing heat losses and improving reliability, supporting global clean energy goals. By advancing solar thermal efficiency, this research contributes to sustainable energy transitions and the broader adoption of renewable technologies worldwide.
