Abstract: This study investigates the screening of lithium‐based salts in non‐aqueous electrolyte solutions of monoethanolamine (MEA) for potential use in integrated carbon capture and conversion (ICCC) technology. Experimental measurements of density, viscosity, nitrous oxide (N2O) solubility, and CO2 solubility were conducted for various lithium salts, including lithium chloride (LiCl), lithium bromide (LiBr), and lithium nitrate (LiNO3), in MEA–dimethyl sulfoxide (DMSO) system at 303.15 K at different CO2 pressures ranging from 344 to 1379 kPa. The results indicated that the addition of lithium salts to the amine solution significantly enhances CO2 absorption capacity, exceeding the benchmark value of 0.5 mol CO2/mol MEA typically reported for 5 M MEA aqueous systems. The highest CO2 solubility in the system was observed following the order 2 M MEA + 0.5 M LiBr
