Abstract
This paper reviewed the sensible thermal storage systems specifically designed for cooking applications. The review focuses on the characteristics of storage materials, their practical applications, and the overall performance of the systems. The review consolidated an array of experimental and numerical research published across various sources such as journals, conferences, books, online resources, and professional reports. A systematic review is used to reach the conclusion of this paper. Significant findings from this study include the wide range of storage capacities attained from small-scale systems that can store ~1–5 MJ of energy for a single meal to bigger systems that can store ~10–50 MJ. Some systems are made for low-temperature cooking ≤ 100 ℃, while others may achieve temperatures of over 300°C for uses like baking or frying. Additionally, the overall efficiency of the systems ranges from 50% to 90% due to charging and discharging losses; this condition emphasizes the importance of optimal designs to reduce heat loss. Materials such as rocks, concrete, and specialized phase change materials exhibit varying thermal conductivities from 0.1 to ~5 W/mK and specific heat capacities from 700 to over 2000 J/kgK, which directly affect the performance of the systems. Furthermore, the research also identified gaps in knowledge concerning the durability of storage mediums and the feasibility of integrating cookers with storage systems. The development and implementation of sensible heat storage systems for cooking applications are in early stages of innovation but have the potential to save energy, especially from intermittent sources.
