Direct Air Capture and Mineral Carbonation Approaches for Carbon Dioxide Removal and Reliable Sequestration: Proceedings of a Workshop?in Brief (2018)Board on Atmospheric Sciences and Climate
Direct air capture (DAC) refers to a range of technologies that capture carbon dioxide (CO2) from ambient air. These technologies include chemical scrubbing processes that capture CO2 through absorption or adsorption separation processes. DAC can also refer to processes that involve rapid mineralization of CO2 at the Earth's surface, termed mineral carbonation.
This new publication summarizes a webinar and workshop that addressed:
-- Technological readiness of DAC technologies, including cross-cutting considerations and potential environmental impact;
-- Scientific questions for developing a research and development agenda for DAC, and assessment of co-benefits, costs, and barriers to implementation of this technology at significant scales.
