Metal and phase change material (PCM) is used for thermal storage system.Aluminum as a metal and erythritol as the PCM is a better option for the thermal storage. This thermal storage is charging with the help of solar energy through a solar collector. Parabolic trough solar collector is used to collect the solar energy. Evacuated tube was used to absorb solar radiation and soybean oil-based nanofluid containing Al 2 O 3 nanoparticles at volume concentration of 0.1% is filled in tube to transfer heat from absorber tube to thermal storage. Nanofluid was prepared with the help of ultrasonication. The heat transfer from the absorber to thermal storage through self-circulation unit. Experimentation is carried out with and without nanofluid. Nanofluid of soybean oil and Al 2 O 3 is enhanced the performance of solar collector. The thermal storage and absorber temperature is reached upto the 153 C and 178 C while using nanofluid. The discharging of PCM is carried out through experimentation.The PCM is filled in thermal storage, which changes its phase and stores the energy which can be used at night when solar energy is not available.

“…The PCM is filled in the cylinder of aluminum and heating by the help of HTF through the conduction. Thermal conductivity of metal plays important role in this phenomenon of heat transfer from one medium to another . Foam skeleton of aluminum metal using BCC and FCC structure has been made and PCM is filled in the whole structure.…”

“…Although the storage tanks stored PCM during the phase change period, the storage tanks also stored sensible heat before the phase change process. The charging of an oil-based heat storage tank coupled with a low-cost, small-scale, solar parabolic trough for cooking purposes was done by Mussard and Nydal (2013b). The loop connecting the collector and the storage was filled with the heat transfer oil, which circulated by self-circulation.…”

Many of today's solar cookers lack energy storage and their applications have been limited to day time use while the sun is shining. In addition these cookers need longer cooking time and are less versatile to users compared with the traditional wood stoves. This article presents tests of a solar stove with and integrated heat storage designed to satisfy a particular need of some east African countries to bake their daily food (Injera). The prototype was tested in the solar laboratories at NTNU and Mekelle University, and presented for community demonstrations in Mekelle. Steam is used as heat carrier between a receiver in the focal point of a concentrating dish and a solar salt based latent heat storage. The stored heat enables users to bake at any time. The storage has a capacity to retain usable thermal energy for about one to two days depending on the amount of insulation. This system can supplement the existing electric and biomass Injera stoves and provide inexpensive and clean energy solution for food preparation. Solar baking provides benefits in terms of human health, environmental strain and high costs associated with biomass fuel.
