John Warwick Lab AI: Amanda Le Sueur April 2, 2011 Heat Storage of Sodium Thiosulfate Pentahydrate for Solar Heating Introduction The development of clean and renewable sources of energy is becoming more important on earth with each passing year. The current fossil fuels such as coal, oil, and natural gas are not unlimited sources of energy for our planet. When fossil fuels are used to create energy, they negatively affect the environment and wildlife of planet earth. Therefore it is critical that new energy sources are developed for the near future. One clean energy source that is already being used on our planet is solar energy. The two main ways of converting the solar radiation given off by the sun are photovoltaic cells and solar thermal heat. Solar thermal heating uses solar energy collectors to heat a fluid, while photovoltaic cells are made of silicon alloys which convert sunlight into electricity. Specifically in this experiment a solar energy storage system was used that is based on sodium thiosulfate pentahydrate, , a low melting salt. The low melting point (48) is important because it can be gathered by the solar collectors. The salt also forms crystals that can be transported easily and stored in heat storage containers. The purpose of this experiment was to determine if sodium thiosulfate pentahydrate could store enough energy to make it viable for use in solar heating. Calorimetry was used to measure the heat that was released when the salt was being frozen. Using the data that was collected using the calorimeter, a heating curve was created. The heating curve was used to extrapolate from the point where temperature
