Carbon sequestration is the process of storing carbon in a carbon pool. [2]: 2248 It plays a crucial role in limiting climate change by reducing the amount of carbon dioxide in the atmosphere. There are two main types of carbon sequestration: biologic (also called biosequestration) and geologic. [3]
Direct air capture and carbon storage: a process of capturing carbon dioxide directly from the ambient air (as opposed to capturing from point sources, such as a cement factory or biomass power plant) and generating a concentrated stream of CO 2 for sequestration or utilization or production of carbon-neutral fuel and windgas.
Blue carbon is defined by the IPCC as "Biologically driven carbon fluxes and storage in marine systems that are amenable to management." [2]: 2220 Another definition states: "Blue carbon refers to organic carbon that is captured and stored by the oceans and coastal ecosystems, particularly by vegetated coastal ecosystems: seagrass meadows, tidal marshes, and mangrove forests."

As organic matter is decomposed, carbon is released in various forms, including carbon dioxide (CO2) and dissolved organic carbon (DOC). However, not all of the carbon released during decomposition is immediately lost to the atmosphere; a significant portion is retained in the soil through processes collectively known as soil carbon sequestration.
Forms of carbon sequestration such as geological storage require pure CO 2 products (concentration > 99%), while other applications such as agriculture can function with more dilute products (~ 5%). Since the air that is processed through DAC originally contains 0.04% CO 2 (or 400 ppm), creating a pure product requires more energy than a dilute ...
The terms carbon capture and storage (CCS) and carbon capture, utilization, and storage (CCUS) are closely related and often used interchangeably. [11] 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. [11]
The Carbon Sequestration Leadership Forum (CSLF) is an international initiative to advance carbon capture and storage (CCS) technology. The Forum is a Ministerial-level organization that includes 23 member countries and the European Commission. [ 1 ]
