ADVANCING A LOW-TEMPERATURE, LOW-COST DIRECT AIR CAPTURE SYSTEM BASED ON ORGANIC CHEMISTRY. THE RECIPIENT WILL CONDUCT BENCH-SCALE TESTING OF A NOVEL, TRANSFORMATIVE DIRECT AIR CAPTURE (DAC) PROCESS USING AMINO ACIDS AND GUANIDINES COMPOUNDS. THE PROJECT’S PRIMARY OBJECTIVE IS TO ELEVATE THE TECHNOLOGY FROM A RESEARCH STATE TO AN EXPERIMENTALLY DEMONSTRATED PROOF-OF-CONCEPT LEVEL TO ASSIST THE U.S. DEPARTMENT OF ENERGY (DOE) OFFICE OF FOSSIL ENERGY AND CARBON MANAGEMENT (FECM) IN ACHIEVING THE CARBON NEGATIVE SHOT TARGET OF UNDER $100/NET METRIC TON (TONNE) CARBON DIOXIDE EQUIVALENT (CO2E) REMOVED (I.E., BOTH CAPTURE AND STORAGE), BY 2031. MAIN PROJECT TASKS INCLUDE PROGRAM MANAGEMENT AND PLANNING, DE-RISKING SORBENT COSTS, DEVELOPMENT OF TRANSFORMATIVE LIQUID-SOLID SEPARATION PROCESS, CONTACTOR DESIGN AND OPTIMIZATION OF CARBON DIOXIDE (CO2) ABSORPTION, AND ADVANCED DESORPTION PROCESSES TO REDUCE THERMAL ENERGY REQUIREMENTS.
