  2. Carbon capture and storage - Wikipedia

    en.wikipedia.org/wiki/Carbon_capture_and_storage

    The terms carbon capture and storage (CCS) and carbon capture, utilization, and storage (CCUS) are closely related and often used interchangeably. [3] Both terms have been used predominantly to refer to enhanced oil recovery (EOR) a process in which captured CO 2 is injected into partially-depleted oil reservoirs in order to extract more oil. [3]

  3. Carbon sequestration - Wikipedia

    en.wikipedia.org/wiki/Carbon_sequestration

    Accelerating passive CO 2 sequestration via mineral carbonation may be achieved through microbial processes that enhance mineral dissolution and carbonate precipitation. [119] [120] [121] Carbon, in the form of CO 2 can be removed from the atmosphere by chemical processes, and stored in stable carbonate mineral forms. This process (CO

  4. Trapping mechanisms for carbon geosequestration - Wikipedia

    en.wikipedia.org/wiki/Trapping_mechanisms_for...

    Trapping mechanisms for carbon geosequestration prevent carbon dioxide stored in geological structures from leaking into the atmosphere. As a means to lower greenhouse gas emissions, carbon dioxide from carbon sequestration, especially in terms of carbon capture and storage, is able to be directed from power plants and other sources of greenhouse gas emissions, with carbon dioxide emissions ...

  5. Carbfix - Wikipedia

    en.wikipedia.org/wiki/Carbfix

    Carbfix is an Icelandic company founded in 2007. It has developed an approach to permanently store CO 2 by dissolving it in water and injecting it into basaltic rocks. Once in the subsurface, the injected CO 2 reacts with the host rock forming stable carbonate minerals, thus providing permanent storage of the injected CO 2 [1]

  6. Calcium looping - Wikipedia

    en.wikipedia.org/wiki/Calcium_looping

    Calcium looping (CaL), or the regenerative calcium cycle (RCC), is a second-generation carbon capture technology. [1] It is the most developed form of carbonate looping, where a metal (M) is reversibly reacted between its carbonate form (MCO 3) and its oxide form (MO) to separate carbon dioxide from other gases coming from either power generation or an industrial plant.

  7. Geochemistry of carbon - Wikipedia

    en.wikipedia.org/wiki/Geochemistry_of_carbon

    Under 0.3 GPa pressure, carbon dioxide is stable at room temperature in the same form as dry ice. Over 0.5 GPa carbon dioxide forms a number of different solid forms containing molecules. At pressures over 40 GPa and high temperatures, carbon dioxide forms a covalent solid that contains CO 4 tetrahedra, and has the same structure as β ...
