Hot potassium carbonate, HPC, is a method used to remove carbon dioxide from gas mixtures, [1] in some contexts referred to as carbon scrubbing. The inorganic, basic compound potassium carbonate is mixed with a gas mixture and the liquid absorbs carbon dioxide through chemical processes. [ 2 ]
A carbon dioxide scrubber is a piece of equipment that absorbs carbon dioxide (CO 2). It is used to treat exhaust gases from industrial plants or from exhaled air in life support systems such as rebreathers or in spacecraft , submersible craft or airtight chambers .
Direct air carbon capture and sequestration (DACCS) is the use of chemical or physical processes to extract CO 2 directly from the ambient air and putting the captured CO 2 into long-term storage. [119] In contrast to CCS, which captures emissions from a point source, DAC has the potential to remove carbon dioxide that is already in the atmosphere.
Scientists have developed a new carbon capture system that absorbs CO2 and produces useable electricity and hydrogen fuel.
Direct air capture (DAC) is the use of chemical or physical processes to extract carbon dioxide (CO 2) directly from the ambient air. [1] If the extracted CO 2 is then sequestered in safe long-term storage, the overall process is called direct air carbon capture and sequestration ( DACCS ), achieving carbon dioxide removal .

Calcium looping is a promising second generation post-combustion capture technology in which calcium oxide, often referred to as the "sorbent", is used to separate CO 2 from the flue gas. The ANICA project focuses on developing a novel indirectly heated carbonate lopping process for lowering the energy penalty and CO 2 avoidance costs for CO 2 ...
The electrochemical reduction of carbon dioxide, also known as CO2RR, is the conversion of carbon dioxide (CO 2) to more reduced chemical species using electrical energy. It represents one potential step in the broad scheme of carbon capture and utilization .
