Negative emissions technologies (NETs) that aim to remove and sequester excess carbon from the atmosphere have been identified as an important part of the portfolio of responses to climate change. These approaches have been garnering new attention as the international community has identified lower thresholds for global temperature increases, which can only be accomplished with net negative carbon emissions to the atmosphere. This new report aims to develop a detailed research and development agenda needed to assess the benefits, risks, and sustainable scale potential for carbon dioxide removal and sequestration approaches; and increase their commercial viability.
A public briefing of the report will be held on Wednesday, October 24, 2018 at 11 am EDT. Please register to attend in person at the National Academy of Sciences Building in Washington, DC, or to join the webcast.

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 >>
