INTENSIFIED AMMONIA SOLAR REACTOR FOR GREEN AMMONIA MANUFACTURE AND GEN3 THERMOCHEMICAL ENERGY STORAGE. WE PROPOSE AN INTENSIFIED REACTION-ABSORPTION (RXN-ABS) PROCESS FOR ENHANCED THERMOCHEMICAL ENERGY STORAGE (TCES) AND AMMONIA MANUFACTURING. OUR APPROACH IS BASED ON REACTIVE ABSORPTION TO REMOVE AMMONIA AT HIGH TEMPERATURE FROM THE GAS PHASE, IMMEDIATELY AFTER IT IS PRODUCED. THIS TECHNOLOGY PROVIDES A COST-EFFECTIVE PATHWAY TO MANUFACTURE GREEN AMMONIA FOR ENERGY, TCES, AND INDIRECT HYDROGEN STORAGE AND TRANSPORT. IN PARTICULAR, THE PROPOSED PROCESS PROVIDES A SUSTAINABLE AMMONIA-BASED TCES TO BALANCE THE GRID OVER WEEKLY AND SEASONAL TIMESCALES (LONGER THAN PRACTICAL FOR BATTERIES). WE ARE ALSO INTERESTED TO CAPTURE CONCENTRATED SOLAR AND USE THIS MODULAR PROCESS FOR DECARBONIZED AMMONIA MANUFACTURING. IF SUCCESSFUL, THIS PROJECT WILL RESULT IN AT LEAST 50% IMPROVEMENT IN ENERGY EFFICIENCY OF THE AMMONIA-BASED TCES, COMPARED TO THE PREVIOUS BASELINE TECHNOLOGY DEMONSTRATED UNDER SETO’S SUNSHOT PROGRAM. ITS MODULARITY ALSO PROVIDES A UNIQUE FLEXIBILITY TO USE THIS PROCESS FOR SOLAR-BASED AMMONIA MANUFACTURING IN DISTRIBUTED LOCATIONS. THIS PROJECT WILL PAVE THE WAY FOR FUTURE EFFORTS IN DECARBONIZING CHEMICAL INDUSTRY USING RENEWABLE HYDROGEN DERIVED FROM THE SOLAR HEAT.
