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]

Bioenergy with carbon capture and storage (BECCS) is the process of extracting bioenergy from biomass and capturing and storing the carbon dioxide (CO 2) that is produced. Greenhouse gas emissions from bioenergy can be low because when vegetation is harvested for bioenergy, new vegetation can grow that will absorb CO 2 from the air through ...
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 ...
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 ...
A carbon sink is a natural or artificial carbon sequestration process that "removes a greenhouse gas, an aerosol or a precursor of a greenhouse gas from the atmosphere". [2]: 2249 These sinks form an important part of the natural carbon cycle.
Earthen carbon sequestration occurs through the carbon cycle's short and long-term processes: (i) the Earth's process of cycling carbon as life's building blocks (ii) the long-term process of removing carbon out of the atmosphere and sequestering it into geological storage. In the same way, plastic sequestrated blocks have a short and long-term ...
