Humankind is already experiencing the consequences of increase in the global mean surface temperature. DAC2.0 provides a technology option that can contribute to climate change mitigation by directly sequestering carbon dioxide from the atmosphere. The goal of DAC2.0 is to reduce the specific energy of CO2 capture to 4 - 6 kWh/kg CO2 by developing adsorbent-coated extended heat transfer surface (intensified sorbent) and a process design. The essential role of DAC for a fully sustainable energy system and highly competitive CDR technology and its environmental impact are examined. Our multi-scale concept is coupled with our multidisciplinary backgrounds in development of sorbent, metal-organic frameworks (MOFs) and their characterization, multi-scale computational fluid dynamic models. Image processing, life cycle assessment and techno-economic analysis and energy systems modelling are also employed.
