Carbon sequestration. Från Wikipedia

Carbon sequestration is the capture of carbon dioxide (CO₂) and may refer specifically to:

• "The process of removing carbon from the atmosphere and depositing it in a reservoir."^[1] When carried out deliberately, this may also be referred to as carbon dioxide removal, which is a form of geoengineering.

• The process of carbon capture and storage, where carbon dioxide is removed from flue gases, such as on power stations, before being stored in underground reservoirs.

• Natural biogeochemical cycling of carbon between the atmosphere and reservoirs, such as by chemical weathering of rocks.

Carbon sequestration describes long-term storage of carbon dioxide or other forms of carbon to either mitigate or defer global warming and avoid dangerous climate change. It has been proposed as a way to slow the atmospheric and marine accumulation of greenhouse gases, which are released by burning fossil fuels.^[2]
Carbon dioxide is naturally captured from the atmosphere through biological, chemical or physical processes. Some anthropogenic sequestration techniques exploit these natural processes,^[3] while some use entirely artificial processes.
Carbon dioxide may be captured as a pure by-product in processes related to petroleum refining or from flue gases from power generation.^[4] CO₂ sequestration includes the storage part of carbon capture and storage, which refers to large-scale, permanent artificial capture and sequestration of industrially produced CO₂ using subsurface saline aquifers, reservoirs, ocean water, aging oil fields, or other carbon sinks.

”Underjordisk koldioxidförvaring har gått i stå”

DEBATT. EU borde satsa sina miljarder på att tillverka metanol av koldioxiden i stället för att framhärda med projekten med att pumpa ner den i marken, skriver Bengt Lindhé.

I augusti 1986 fick man en illustration på riskerna med lössläppt koldioxid. Vid lake Nyos i Kamerun i Afrika kokade naturligt bildad koldioxid upp ur sjön i form av ett jättelikt moln. 1700 människor och tio gånger fler djur dog inom loppet av några minuter.
Flera debattartiklar på den här sidan förutom publicerad litteratur visar att det finns ett alternativ till CCS som heter CCR där R står för Recycling. Man fångar upp koldioxiden på samma sätt som i CCS men man kombinerar koldioxiden med väte och producerar metanol som kan ersätta bensin eller DME som i sin tur kan ersätta dieselolja. Man skapar på det sättet ett kretslopp för koldioxiden och man slipper plocka upp mer fossila bränslen från jordens innandömen till allt högre kostnader.
