Sequester

From PiqqoWiki

CO2 sequestration is the long term storage of carbon dioxide or other forms of carbon in soil or vegetation through biological processes for the mitigation of global warming. It is the process by which atmospheric carbon dioxide is taken up by trees, grasses and other plants through photosynthesis and stored as carbon in biomass (trunks, branches, foliage, and roots) and soils. The sink of carbon sequestration in forests and wood products helps to offset sources of carbon dioxide to the atmosphere, such as deforestation, forest fires, and fossil fuel emissions.

Besides the before mentioned biological processes, there are also physical (eg. burying biomass) and chemical processes (applied at power plants for example).

Carbon sequestration methods include the following:

- enhancing the storage of carbon in soil (soil sequestration);

- enhancing the storage of carbon in forests and other vegetation (plant sequestration);

- storing carbon in underground geological formations (geosequestration);

- storing carbon in the ocean (ocean sequestration); and

- subjecting carbon to chemical reactions to form inorganic carbonates (mineral carbonation).
