Carbon dioxide capture from ambient air could compensate for all carbon dioxide emissions to the atmosphere. Such capture would, for example, make it possible to use liquid, carbon-based fuels in cars or airplanes without negatively impacting the climate. We present a specific approach based on a solid sorbent in the form of an anionic exchange resin, that absorbs carbon dioxide when dry and releases it when exposed to moisture. We outline a particular implementation of such a moisture swing… 
Carbon Dioxide Capture from Air: A Simple Analysis
A simplified analysis is presented in order to compare direct capture of carbon dioxide from air, i.e. air capture, and capture from fossil fuelled power plants. For air capture the literature shows
A literature review of CO2 capture directly from ambient air
The concentration of atmospheric carbon dioxide has risen substantially since the beginning of the Industrial Revolution by the burning of fossil fuels. Because of the negative effects that global
Adsorption artificial tree for atmospheric carbon dioxide capture, purification and compression
The current concentration of carbon dioxide in the atmosphere demands for development of negative emission solutions such as direct carbon dioxide removal from the atmosphere (air capture). Many
Economic and energetic analysis of capturing CO2 from ambient air
The thermodynamic efficiencies of commercial separation systems as well as trace gas removal systems are investigated to better understand and constrain the energy requirements and costs of these air capture systems.
The thermodynamics of direct air capture of carbon dioxide
An analysis of thermodynamic constraints shows that the low concentration of carbon dioxide in ambient air does not pose stringent limits on air capture economics. The thermodynamic energy
Sorbents for Direct Capture of CO2 from Ambient Air.
Major types of sorbents designed to capture CO2 from ambient air are reviewed, which are categorized by sorption mechanism: physisorption, chemisor adaptation, and moisture-swing sorption.
The urgency of the development of CO2 capture from ambient air
It is argued that for conventional CCS to become a successful climate mitigation technology—which by necessity has to operate on a large scale—it may need to be complemented with air capture, removing CO2 directly from the atmosphere.
Design of carbon dioxide absorption from polluted city air
Global climate change is the most serious environmental problem which the world is facing now. To avoid dangerous climate change, the growth of atmospheric concentrations of greenhouse gases must be
Capturing CO2 from ambient air using a polyethyleneimine–silica adsorbent in fluidized beds
Carbon Capture and Storage (CCS) uses a combination of technologies to capture, transport and store carbon dioxide (CO2) emissions from large point sources such as coal or natural gas-fired power
Moisture swing sorbent for carbon dioxide capture from ambient air.
Equilibrium experiments show that the absorption and desorption process can be described well by a Langmuir isothermal model, and the equilibrium partial pressure of carbon dioxide over the resin at a given loading state can be increased by 2 orders of magnitude by wetting the resin.


Carbon dioxide extraction from air: Is it an option?
Controlling the level of carbon dioxide in the atmosphere without limiting access to fossil energy resources is only possible if carbon dioxide is collected and disposed of away from the atmosphere.
Process design and energy requirements for the capture of carbon dioxide from air
Abstract A process to capture carbon dioxide from air to reduce its atmospheric concentration and to mitigate climate change is studied. It is based on the absorption of carbon dioxide in a sodium
Carbon dioxide capture from atmospheric air using sodium hydroxide spray.
The analysis indicates that CO2 capture from air for climate change mitigation is technically feasible using off-the-shelf technology.
Carbon Dioxide Capture from Atmospheric Air Using Sodium Hydroxide Spray
In contrast to conventional carbon capture systems for power plants and other large point sources, the system described in this paper captures CO2 directly from ambient air. This has the advantages
The increasing concern over rising CO2 levels in the atmosphere and their potential climate effects is fuelling research aimed at carbon management. One area of research focuses on capturing the CO2
It is physically possible to capture CO2 directly from the air and immobilize it in geological structures. Air capture differs from conventional mitigation in three key aspects. First, it removes

Climate Strategy with Co2 Capture from the Air
It is physically possible to capture CO2 directly from the air and immobilize it in geological structures. Air capture differs from conventional mitigation in three key aspects. First, it removes
Production of synthetic methanol from air and water using controlled thermonuclear reactor power—I. technology and energy requirement
For the extraction of carbon dioxide from air, the process of absorption/stripping of air by dilute potassium carbonate solution is found to require the least amount of energy.
Energetics of solar methanol synthesis from atmospheric carbon dioxide compared to solar liquid hydrogen generation
The energetics of different synthesis methods for the secondary energy carriers hydrogen and methanol are compared. In the case of hydrogen generation by water electrolysis, followed by liquefaction,
