Abstract or Summary
  • Global energy needs are continuously increasing while fossil fuels remain an uncertain resource. With a growing population and demand for energy, alternative energy sources are being pursued to power the future. Fossil fuels are an unsustainable resource that brings along problems of climate change and atmospheric pollution. Concentrated solar power (CSP) is a promising method of converting solar energy into electricity while avoiding carbon emissions. Thermal energy storage (TES) in conjunction with CSP can increase efficiency in power generation and allow for generation beyond on-sun hours. One method of TES is thermochemical energy storage (TCES), which has potential for higher energy density. TCES is based storing energy chemical via reversible reactions. During peak sun hours, the endothermic reaction stores the thermal energy; thus, the reaction can be reversed to produce heat for off-peak sun hours. One reaction that exhibits high energy densities is the reversible carbonation/ decomposition of SrO/SrCO3, which occurs around 1200 °C. The reaction is nontoxic and avoids the use of catalysts. The high reaction temperature leads to a higher Carnot efficiency for power generation, and could enable combined-cycle power production Over many cycles, the material becomes less reactive due to sintering. Sintering inhibitors were looked at to determine if sintering could be hindered. Calcium sulfate and strontium phosphate were tested due to their inert nature and polymorphic properties.
