“…4. The performance of the storage cooking pots during the heat utilisation processes was comparable or slightly better than most of the previously reported works (Chaudhary et al, (2013), Lecuona et al, (2013), Yadav et al, 2017) although optimised storage cooking pot designs by Bhave and Thakare (2018) and Bhave and Kale (2020) showed better heat utilisation characteristics.…”

“…Sunflower oil showed good solar cooking characteristics, but its thermal conductivity needs to be enhanced for it to be more useful during the storage cooking period. Future work will also look at combining both PCM and sensible heat storage material in a single cooking pot to enhance the performance of the pot for both solar and storage cooking periods as reported by Yadav et al, (2017). The effect of different loads of water and sunflower oil on the storage and heat utilisation efficiencies also needs to be studied experimentally and numerically in future work.…”

“…Based on the cost of the three identified types of thermal storage materials, sensible thermal storage materials is cheaper and readily available for people in rural areas and some urban areas of developing countries like Nigeria. Table 1 presents the summary of studies on solar cooker with thermal storage materials (Hussein et al, 2008;Saxena et al, 2013a;Saxena et al, 2013b;Kumaresan et al, 2016;Saxena and Karakilcik, 2017;Yadav et al, 2017;Bhave and Thakare, 2018;Coccia et al, 2018;Saxena and Agarwal, 2018;Keith et al, 2019;Khallaf et al, 2020;Omara et al, 2020;Saxena et al, 2020;Hosseinzadeh et al, 2021;Kanyowa et al, 2021).

Energy need for cooking in both the rural and urban areas all over the world is increasing every day as a result of an increase in population. The consequence of global warming due to the usage of fuels such as fossil fuel, firewood, and other biomass products for cooking necessitates innovative techniques that will improve the standard of living of people. In this study, the design, fabrication, and thermal evaluation of a solar cooking system integrated with an Arduino-based tracking device and sensible heat storage (SHS) materials was investigated. During the water boiling trials with black oil sensible material (BOSHSM), the obtained maximum temperatures for water, cooking box, and sensible heat storage material at 14:00 h when the solar radiation attained its peak value of 881.2 W/m2 were 64,52, and 54°C, respectively, while at 14:00 h with Black coated granite sensible heat storage material (BCGSHSM) at the solar radiation peak value of 890.4 W/m2, the maximum temperatures for water, cooking box, and sensible heat storage material were 73.5, 76, and 59°C, respectively. The maximum cooking power and thermal efficiency obtained from the water boiling trials were 48.4 and 56.4 W, and 31.6 and 35.8% respectively. Also, the results from the cooking of edibles revealed that the cooking power values ranged between 42.5 and 58.2, while that of efficiency ranged between 34.5 and 40.3% respectively. The maximum solar radiation during the cooking trial period was 986, 975, 956, and 953 W/m2. In general, from the results, the developed solar cooking system is a viable alternative to cooking with traditional/open burning of wood or other biomass products that pose a serious environmental and health-related threat to the people living in developing countries.

“…Results showed that one Injera was baked at temperatures in the range of 110-150 C under 3 min. Thermal performance evaluation of a solar cooker with a latent and sensible heat storage unit for evening cooking was done by Yadav et al [117]. The main experimental components consisted of a parabolic solar dish collector, a storage solar cooking vessel, and an insulation box.…”

Biomass and fossil fuels are mostly used in rural areas of developing countries for cooking. These energy resources have negative impacts on the environment and human health mainly due to deforestation and greenhouse gas emissions. A cleaner and environmentally-friendly form of cooking is solar cooking using the sun's energy. Parabolic solar cookers perform better than other solar cookers such as box solar cookers since higher temperatures are achieved in a shorter duration. These higher temperatures allow most types of cooking processes such as; boiling, frying, roasting, and baking to be possible. The major problem with most conventional solar cookers is that cooking is not possible during off-sunshine periods. Integrating solar cookers with thermal energy storage (TES) makes cooking during off-sunshine periods possible. This paper presents a comprehensive review of parabolic solar cookers with TES which is a sustainable cooking solution for developing countries. Previous work on both parabolic trough and parabolic dish solar cookers with TES is presented. Solar cookers with storage are classified according to the two main types of TES technologies which are; sensible heat thermal energy storage (SHTES) and latent heat thermal energy storage (LHTES). The main conclusions of the review are that; parabolic dish solar cookers with TES are more common than parabolic trough cookers, more studies have been done using latent heat storage as compared to sensible heat storage, limited modelling work has been presented, most of the parabolic cookers used aluminum sheets as the reflecting material, large scale experimental studies are limited and fewer studies tackled the techno-economic and socio-economic aspects. The review also highlights research gaps on parabolic solar cookers with TES in terms of the modelling, combined TES (sensible and latent heat), different reflector materials, large-scale experimental setups, and techno-economic and socio-economic analyses. Other important aspects to consider for parabolic solar cookers with TES include; the choice of sensible or latent heat storage materials, environmental impact, types of food to be cooked, and social acceptance.
