Carbon Dioxide Removal


Direct Air Capture

Direct air capture is the technique of scrubbing carbon dioxide directly from the sky through large mechanical facilities. The technique can be used to obtain carbon for making a byproduct or fuel. Direct air capture and storage (DACS) means storing that carbon dioxide in a long-term reservoir. The two main approaches involve either (1) liquids or surfaces that chemically interact with carbon dioxide, or (2) membranes that physically trap the carbon dioxide on solid surfaces.

Emergency deployment of direct air capture as a response to the climate crisis

2021
Scholarly Work
Ryan Hanna, Ahmed Abdulla, Yangyang Xu, David G. Victor
This paper models a wartime-like crash deployment of direct air capture (DAC) as a policy response to the climate crisis, calculating funding, net CO2 removal, and climate impacts.

H.R. 5205 – NET Zero Act of 2021

2021
Proposed Legislation
U.S. Congress
This bill would amend the 45Q tax credit by removing the deadline for DAC to geologic storage and enforcing a 10-year deadline for DAC to EOR.

Reframing the Climate Change Problem: Evaluating the Political, Technological, and Ethical Management of Carbon Dioxide Emissions in the United States

2020
Scholarly Work
Evvan V. Morton
This dissertation argues that climate change must be reframed as a two-part problem: preventing new CO2 emissions and reducing concentrations, which demands increased investment in DAC research, development, and deployment.
