(498c) Solar Thermochemical Energy Storage Based on Strontium Carbonate Chemistry
AIChE Annual Meeting
Wednesday, November 16, 2016 - 9:14am to 9:36am
The SrO/SrCO3 chemistry offers the potential for high temperature heat release (~1100-1200°C) upon the carbonation of SrO, which could be a pathway to high efficiency, combined cycle power generation. Building upon previous work on this cycle, this talk will propose a kinetic model for the carbonation reaction derived on experiments using both TGA and packed bed systems. In addition, preliminary technoeconomic and exergy analyses are performed for the cases of CO2 storage as 1) a compressed gas and 2) ab/adsorbed species in a liquid or solid matrix. Probabilistic methods are used to elucidate the cost drivers and areas for future consideration in evaluation of the cycle feasibility.
