THE PROPOSED PROJECT WILL DEVELOP A SOLAR CALCINER RECEIVER SYSTEM FOR THE PRODUCTION OF LIME, CEMENT, CALCINED CLAY, AND ACTIVATED LIMESTONE. PRELIMINARY TECHNOECONOMIC ANALYSIS HAS IDENTIFIED A PATHWAY TO A LEVELIZED COST OF HEAT, LCOH = 0.02 $/KWHTH AT INTERNAL CALCINATION TEMPERATURES OF 950°C, WHICH IS HIGH ENOUGH TO SERVE ALL THE AFOREMENTIONED PRODUCT MARKETS. THE THREE-YEAR PROJECT INCLUDES LAB-SCALE TESTING, MULTI-PHASE REACTOR MODELING FOR DESIGN AND SCALE-UP, AND ON-SUN TESTING FOR CALCINATION TO 400 KWTH.
