Page 11: Research news on Carbon capture utilization
Carbon capture utilization encompasses technologies that separate carbon dioxide from air, flue gas, or aqueous streams and convert it into fuels, chemicals, and materials. Approaches span sorbent- and solvent-based capture, moisture- and pressure-swing processes, chemical looping, and direct air capture, often integrated with solar, electrochemical, and bio-based systems. Captured CO2 and biogenic carbon are transformed via catalysis, photoelectrochemistry, microbial and thermochemical pathways into products such as methane, methanol, formic acid, plastics, bio-oil, and solid carbon, frequently using waste biomass, wastewater, and plastics as feedstocks.
