Ah-Hyung Alissa Park is a chemical engineer whose research concerns carbon capture and storage, together with carbon dioxide utilization and the development of materials and processes for more sustainable energy systems. Her UCLA profile describes nanohybrid materials for carbon dioxide capture and conversion, together with work on chemistry of carbonates, recovery of critical minerals and rare-earth elements.^[ref]

The scientific connection is between material structure and a chemical process: the way a material binds or reacts with carbon dioxide determines how it can be separated, transformed or stored. Evaluating such a process also requires tracking material flows and energy use through the larger system. This links surface chemistry, chemical reaction engineering and the assessment of alternative process designs rather than treating capture alone as the complete objective.^[ref]

Carbon dioxide utilization uses captured carbon dioxide as a feedstock or working material. Chemical conversion can produce fuels and other compounds; mineralization can incorporate carbon into inorganic materials. These routes differ in their energy requirements and in how long the carbon remains out of the atmosphere.^[ref][ref]

Reducing carbon dioxide to an energy-rich fuel requires an external energy supply. Burning that fuel later can return the carbon to the atmosphere, so utilization is not automatically permanent carbon capture and storage. A life-cycle assessment must compare the whole process with a stated alternative, including energy generation, capture, conversion and product use.
