Professor Dongwoo Kang's research lab specializes in carbon capture, utilization, and storage (CCUS) technologies, with a strong focus on developing advanced materials and processes for efficient CO₂ capture and conversion into valuable industrial products. The lab investigates novel absorbents such as amino acid salt solutions, deep eutectic solvents (DESs) hybridized with zeolites, and alkanolamine-based systems for enhanced CO₂ absorption and stability under flue gas conditions. A key research direction involves the chemical conversion of captured CO₂ into high-purity calcium carbonate using seawater-based industrial wastewater, enabling sustainable resource recovery and reducing environmental impact. The lab also explores co-firing strategies in power plants using hydrogen, ammonia, and methanol to decarbonize energy systems while evaluating technical and economic feasibility under net-zero scenarios.

Amino acid salt solutions are useful as carbon dioxide absorbents. In this study, vapor–liquid equilibrium (VLE) experiments were conducted using 4 M K-SAR, 1.5 M K-ALA-PZ, and 1.5 M K-SER-PZ solutions. Partial pressures and solubilities were measured for each absorbent solution at temperatures of 313.15 K, 333.15 K, and 353.15 K. The range of CO2 partial pressure measured at 313.15 K over 4 M K-SAR was from 0 kPa to 812.5 kPa with loadings from 0.06 to 0.98. The partial pressures of CO2 ranged
Abstract This study investigated the capture of carbon dioxide (CO 2 ) and its chemical conversion to high‐purity calcium carbonate salt, which has potential uses in a range of industrial sectors. Indirect inorganic aqueous carbonation methods were used, with seawater‐based industrial wastewater as the source of metal ions. The alkanolamine absorbent solutions of monoethanolamine (MEA), diethanolamine (DEA), and methyldiethanolamine (MDEA) were used at typical industrial concentrations of 30 wt%
