Webinar on Direct Air CaptureBoard on Atmospheric Sciences and Climate
October 5, 2017
Webinar objective: to provide an introduction to Direct Air Capture (DAC) as a carbon dioxide removal approach, specifically panelists will explore the limitations, appropriate scale, and future cost of DAC technology. Panelists will describe technological readiness, current research needs, and potential environmental impact.

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: -... More >>
Bioenergy with carbon capture and storage (BECCS) is a technology that integrates biomass conversion to heat, electricity, or liquid or gas fuels with carbon capture and sequestration. BECCS could provide a significant portion of the global energy supply if deployed to its theoretical maximum feasible amount. The future role of BECCS is a subject that divides researchers as estimates of potential future biomass supply vary widely due t... More >>
Geologic carbon capture and sequestration encompasses approaches for relatively permanent storage of carbon in the Earth's geologic formations. Carbon dioxide (CO2) that has been captured from flue gas or other waste streams as pressurized fluids can be trapped geologically through thermodynamically favorable reactions between CO2 and silicate rocks to create stable mineral carbonates. This mineralized carbon is stored permanently i... More >>
