ELECTROCHEMICALLY MEDIATED AIR SEPARATION MODULES (EM-ASM) TO ADVANCE THE TECHNOLOGY READINESS LEVEL (TRL) OF A NOVEL ELECTROCHEMICALLY ACTIVATED OXYGEN SORBENT AND ELECTROCHEMICAL REACTOR COMBINATION.THE PROJECT TARGETS THE DEVELOPMENT OF A SCALABLE, EFFICIENT, COST-EFFECTIVE, AND DURABLE ELECTROCHEMICALLY MEDIATED OXYGEN SEPARATION TECHNOLOGY THAT GENERATES OXYGEN OF SUFFICIENT PURITY TO ENABLE HIGH-QUALITY SYNGAS PRODUCTION AND EFFICIENT PRE-COMBUSTION CARBON CAPTURE FOR HYDROGEN PRODUCTION FROM GASIFICATION OF BIOMASS AND WASTES. THE PROPOSED PROJECT IS COMPRISED OF FOUR MAJOR TECHNICAL ELEMENTS: (1) THEORETICAL SCREENING OF CANDIDATE TRANSITION METAL (TM) COMPLEXES VIA MOLECULAR MODELING FOR KEY METRICS FOR AN ELECTROCHEMICALLY ACTIVATED OXYGEN CARRIER WHICH MAY INCLUDE REVERSIBLE POTENTIAL, SOLUBILITY, AND OXYGEN BINDING, (2) SYNTHESIS AND EXPERIMENTAL SCREENING OF PROMISING CANDIDATE TM COMPLEXES, (3) SMALL-SCALE REACTOR DESIGN, FABRICATION, AND TESTING OF PROMISING TM COMPLEXES, AND (4) MODELING OF SEPARATION PROCESSES WITH SINGLE AND MULTIPLE UNIT OPERATIONS, REACTOR AND SEPARATOR MODELING, DESIGN FOR SCALE-UP, TECHNO-ECONOMIC MODELING, AND STAGING WITH CONVENTIONAL MEMBRANE-BASED AIR SEPARATION TECHNOLOGIES.
