Advancing Solar Still Performance with Nano-Integrated Thermal Energy Storage Systems

Abstract

Obtaining safe drinking water is still a major worldwide concern, especially in resource-limited regions. Solar distillation provides an eco-friendly and cost-effective solution and this study advances the field by integrating innovative materials into hybrid solar still systems. By combining phase change materials (PCMs) such as stearic acid, lauric acid, and Paraffin wax with nanoparticles like CuO and TiO₂, the research introduces a groundbreaking approach to optimizing heat transfer and enhancing water productivity. The experimental setup features a solar still connected to a solar water heater, employing advanced materials to boost energy efficiency and distillate output. This novel integration significantly improves exergy performance, pushing the boundaries of conventional solar still technologies. The results reveal a transformative leap in water production efficiency, demonstrating the potential of sustainable, innovative solutions to tackle global water scarcity. This study redefines the capabilities of solar distillation systems, showcasing how the synergy between PCMs and nanoparticles can revolutionize water purification in a practical, scalable, and environmentally responsible manner.
