Integration of Thermal Storage in Solar Cooking for Night-Time Use

Abstract

Solar cooking is a sustainable and eco-friendly alternative to conventional cooking methods, reducing reliance on fossil fuels and minimizing environmental impact. However, one of the primary limitations of solar cookers is their inability to function efficiently during nighttime or periods of low solar radiation. This study explores the integration of thermal energy storage (TES) systems in solar cookers to extend their usability beyond daylight hours. Various thermal storage materials, including phase change materials (PCMs) and sensible heat storage mediums, are examined for their heat retention capabilities and efficiency in maintaining optimal cooking temperatures. The research highlights the thermophysical properties, energy storage capacity, and discharge characteristics of different TES systems, emphasizing their role in enhancing the performance of solar cookers. Experimental and simulation-based analyses demonstrate that incorporating TES significantly improves cooking efficiency and usability during nighttime,
