Asked 2 August 2016
What is the critical difference between Carbon Capture and Storage (CCS) and Carbon Sequestration?
If both are same, why we would use different words with same meaning?

@Rudiger The key difference between carbon capture and storage and carbon sequestration is that carbon capture and storage involve capturing, transporting, and storing carbon dioxide, while carbon sequestration only involves storing carbon dioxide for a longer period of time.

As I know, carbon capture is usually used as a term describing a technology used to capture carbon.
Carbon sequestration and storage are often used to describe carbon sequestered or accumulated by vegetation or sediment. But there is a little difference. When it concerns about the capacity of carbon sequestration, carbon sequestration rate is used. When it concerns about the amount of carbon stored in sediment, carbon store is used.
Please refer to a paper below regarding carbon sequestration and carbon storage.

Thank you Dr. Grote for your detailed answer regarding CCS and CS.

CCS describes the complete process of carbon capture and carbon storage or sequestration. Sequestration is more general. It can mean simple storage of CO2, for example in exhausted reserves of gas, injection to enhance oil recovery, or dissolving it the in the ocean. But more recently it includes also the chemical fixation of CO2 to form carbonates.

The answer from Rüdiger Grote is very accurate. Some addition on why the two terms co-exist.
Therefore, just as a (partly historical) addition: CCS (resulting in geological storage) originally referred to Carbon Capture and Sequestration, in order to emphasize the long-term or near-permanent character.
In the EU, CCS was re-coined as Carbon Capture and (geological) Storage. This was mainly done by the PR people from the Zero Emission Platform, who liked the sound of Storage better than that of Sequestration. This change of terminology was adopted by the European Commission, more or less during the drafting of the CCS Directive, if I recall well.
In contradiction to its 'temporary' character, in the EU sequestration will commonly be used for all non-geological storage (biomass, soils, etc.).
Outside of the EU, sequestration remains to be used for geological storage (e.g. CSLF). I'm so used to seeing both terms, that I can't tell if this divide is still as sharp as it used to.

Dear Dr. Gaur,
If you make this a starting question, I'll be happy to provide input. As background, at least in Europe there are several projects looking into co-use of the underground, including CGS and groundwater, considering both socio-economic, environmental and sustainability aspects.

Dear Mr. Gaur,
Of course underground storage is not the best solution, in termes of sustainability. Better solutions are being investigated converting CO2 in useful products, such as for example in commercial plastics:
Or in ethanol:

would u plz describe difference between "CO2 Recovery" and "Carbon capture & Storage"?
they do the same thing, I mean: CCS is established by three methods:
-pre-combustion capture
-post-combustion capture
-oxy-fuel combustion.
and "post-combustion method" uses a solvent for absorption, similar to described for CO2 recovery.
and still I don't Know the difference.
can you help me?

"CO2 Recovery" and "CO2 Capture" is about the same. "CO2 Storage" comes after CO2 is captured. Storage means normally storage in underground reservoirs, and also to enhance oil recovery from oil wells.
CO2 can also be fixed after capturing. For instance injecting it in greenhouses to accelerate growth of plants. Or converting it into chemicals. See more: http://alchemy.cchem.berkeley.edu/static/pdf/innovativechemistry.pdf

Hello,
I am making a research about my energy storage project for now. However, I am searching for methods of carbon capturing from flue gas. In the articles, I see carbon dioxide capturing methods (i.e. Post-Combustion) and carbon dioxide separation methods (i.e. Absorption). Are they different steps that one followed by other or are they the same ? I am confused by the descriptions a little bit.
Thank you.

carbon sequestration refers in UFORE to the removal of carbon (in the form of carbon dioxide) from the atmosphere through the process of photosynthesis.
carbon storage refers to the amount of carbon bound up in woody material above and below ground

Sequestration done by plants as a natural physiological cheaper process whereas capture is a physico-chemical-mechanical costlier process, both leading to reduction in available Carbon di Oxide in the atmosphere. K P Dubey,

(Carbon Capture and Storage) CCS principal goal is to prevent carbon dioxide from being released into the atmosphere by large and heavy enterprises in order to reduce greenhouse gas emissions. Carbon dioxide is supposed to be stored in deep geological formations or in the form of mineral carbonates.
whereas,
Carbon sequestration is the act of absorbing and storing carbon dioxide over a lengthy period of time in order to prevent it from entering the atmosphere. This provides for the stability of carbon in both solid and dissolved forms, preventing an increase in atmospheric temperature. Sequestrations of carbon might be biological or geological.
The main point to be noticed is : CCS is the process of capturing emitted carbon dioxide, transporting it to a storage facility, and depositing it in a way that prevents it from entering the atmosphere.

According to the Wikipedia, the CCS includes three processes: 1) Capturing CO2 before entering into the atmosphere, 2) Transporting it to a designated place for storing, and 3) Storing CO2 process, which is called "Carbon Sequestration".

In order to do the sequestration process, we have to capture the carbon dioxide.

Sequestration is the rate of carbon storage; there is a time factor like age of trees etc. you can consult this report
