(532c) Carbon Capture

The scale by which CO₂ must be mitigated worldwide dwarfs the existing chemical industry, making utilization of CO₂ as a chemical feedstock a minor component of the portfolio of mitigation options. Carbon capture and storage is one strategy that could potentially mitigate gigatons of CO₂ emissions per year, provided geological storage of CO₂ is feasible. The scale and energy requirements associated with CO₂ separation processes will be presented. Strategies based upon solid sorbent and solvent-based strategies will be discussed. The role of direct air capture in terms of negative emissions technologies will be of focus.
