Advanced Direct Air Capture of CO2 Using Air Conditioning Systems

Addressing poor indoor air quality in urban areas like Doha, our project focuses on modifying A/C units to capture CO2, offering a potential breakthrough in greenhouse gas control. The current A/C system circulates outdoor air indoors, with our approach using swing surface-modified filters to adsorb CO2 in incoming air. Saturated filters undergo regeneration, releasing captured CO2 for utilization. Material selection, vital for filter performance, includes options like polymers and carbon, capable of withstanding high temperatures for effective CO2 release.

Objectives And Goals

Develop and design the overall DAC system.
Screen and select materials for an AC filter that meet existing standards.
Model the thermodynamic properties of the proposed adsorption material with filter.
Test adsorbent/filter composite in the lab to mimic the real A/C operating conditions.
