Abstract, University of Gavle, 2020

This report studies the importance of solar cooking when moving towards a more sustainable and egalitarian future. The problems regarding its implementation, in fact, technological, social and economic problems, are presented. A historic overview is offered as well as the theory behind the technology. After studying the current situation concerning cooking, different devices have been analysed and considered, from small ones suitable for households to bigger ones for institutions. Furthermore, several backup systems are also proposed aiming to obtain an ideal Integrated Solar Cooker (ISC). Possible hybrid systems have also been evaluated during the work. Furthermore, state-of-the-art technology in Thermal Energy Storage (TES) is also commented and taken into account for the most efficient combination of technologies. Several photovoltaic kitchens are mentioned in this report as well.

Two main conclusions have been drawn: trying to solely rely on the sun is a mistake and the ideal and universal ISC does not exist. Other factors besides the income are determinant when choosing an energy source, therefore, a thorough investigation in every particular case is completely necessary for a successful implementation of an ISC.

However, the countless devices available make the adoption of solar technology possible in every situation, helping to achieve some of the Sustainable Development Goals.

Keywords: solar cooking, thermal energy storage, Phase Change Materials, energy consumption cooking, institutional cooking, energy sources cooking.
