“…However, as reported in the literature, based on the thermal stability test, the maximum temperature of PCM as a means of solar cooking is around 120 • C. Indirect heating is found to be the most suitable mode of heating when PCM is incorporated as a heat storage material, for which the temperature drop between the cooking container surface and storage material would be approximately 10-15 • C. Thus, it can be deduced that the maximum possible temperature of the cooking vessel surface is 100 • C, which is below the temperature needed for frying and fast cooking. In order to overcome this problem, a solar cooking system using PCM A-164 as the storage medium is still being studied [128][129][130]. This system consists of a solar collector with a concentrator, a PCM based thermal storage unit and an indoor cooking unit [131].…”

Solar energy is a renewable energy source that can be utilized for different applications in today’s world. The effective use of solar energy requires a storage medium that can facilitate the storage of excess energy, and then supply this stored energy when it is needed. An effective method of storing thermal energy from solar is through the use of phase change materials (PCMs). PCMs are isothermal in nature, and thus offer higher density energy storage and the ability to operate in a variable range of temperature conditions. This article provides a comprehensive review of the application of PCMs for solar energy use and storage such as for solar power generation, water heating systems, solar cookers, and solar dryers. This paper will benefit the researcher in conducting further research on solar power generation, water heating system, solar cookers, and solar dryers using PCMs for commercial development.

“…It depends on the sun shine to work and therefore cannot be a stand-alone technology. Solar is a clean source of energy for domestic cooking [7] and institutional cooking [8]. Other researchers have proposed the use of solar induction stoves that are very efficient and option for clean cooking [13].…”

Accessing affordable and reliable energy services for cooking is important in most developing countries. Improving access to affordable energy reduces effects on human health and environmental influences caused by burning of various biomasses. This review examines the energy resources available in the world and their use in cooking. It also looks at challenges and the ways these energy resources are used as well as possible solutions to such challenges. The major challenges facing the use of available fuels are low efficiencies, high cost, un-sustainability and indoor house pollution that affect many people. The paper has identified that the use of combustion-less cooking, the use of solar for cooking, hydrogen and electrical systems that improve cooking activities and therefore overcome indoor and environmental pollution. Research findings indicate that the pressure-cooking concept improves energy efficiencies in boiling operations. Other energy efficiency improvement techniques in cooking are insulation, containment of escaping steam while cooking and automating the cooking vessel with micro-controllers. The overall efficiencies for electrical induction heating, natural gas, traditional cooking stoves, fuel wood stoves and electrical resistive heating was found to be 90%, 45-60%, 10%, 23-40% and 75% respectively. Induction cooking is both faster and more efficient than gas cooking, while electrical energy systems as a whole were found to be the cleanest, offering ease of control and versatility. The combination of a micro-controller automated insulated pressure cooker and induction cooker can highly improve the cooking efficiency. This is done by cutting a power supply using a relay controlling an induction cooker and therefore preventing the exit of steam. It is therefore identified that zero emission release during cooking will reduce both indoor and environmental pollution significantly.

To run the Solar energy appliances, the continuous availability of solar energy is an essential. The Solar appliances are run by using solar energy either from PV cell or solar collector. Both of these devices require continuous solar rays. In order to use the solar energy after sunshine, it requires being stored first and then can be transferred to the appliances. One of the focused applications by using solar energy is the solar cooking. A Lot of research is going on the use of solar energy for cooking. But still, some extensive technique needs develop for easily usable systems. The various solar cookers are discussed to insist the need for development of solar storage systems for efficient cooking. This paper presents the comparative study of heat storage and transfer systems for solar cooking. The key aspects like, methodology to develop the heat storage system, requirements and properties of heat storage materials, need of insulations and their types are addressed. Some most usable materials are also analyzed.
