Recent research published in ‘Scientific Reports’ has unveiled a promising advancement in the realm of energy storage through the innovative use of paraffin-based phase change materials (PCMs) enhanced by a hybrid sand core matrix. Conducted by Hossam A. Nabwey from the Department of Mathematics at Prince Sattam Bin Abdulaziz University, this study explores an effective method for managing mining waste while simultaneously improving solar energy storage systems.
The research focuses on the valorization of iron extracted from mining wastewater, which is combined with sand to create a sand core. This sand core is then encapsulated in paraffin to enhance its performance as a PCM. The study’s findings indicate that the encapsulated sand core-PCM can significantly improve the thermal efficiency of solar energy systems.
During experiments conducted at peak solar intensity, the researchers found that the heat gained from the system increased dramatically, from 7 to 48 kJ/min when utilizing a 1.5%-sand core-PCM blend. This substantial enhancement translates to an impressive 92% increase in system efficiency, marking it as a potential breakthrough in solar energy storage solutions.
Nabwey stated, “The results showed the system is a good candidate for increasing the system efficiency and presents a potential solution for solar energy storage during off-peak periods.” This is particularly relevant for industries looking to optimize energy use and reduce costs, as improved solar energy storage can lead to more reliable and sustainable energy systems.
The commercial implications of this research are significant. Industries involved in renewable energy, waste management, and materials science stand to benefit from the integration of these enhanced PCMs into their operations. By utilizing mining waste and improving energy storage capabilities, companies can not only reduce their environmental footprint but also enhance their economic viability.
As the demand for sustainable energy solutions continues to grow, this innovative approach could pave the way for new technologies that capitalize on both waste valorization and improved energy efficiency. The findings from Nabwey’s study provide a clear pathway for further research and development in this field, potentially leading to commercially viable products that address both energy storage and waste management challenges.
