After full equilibration with air, up to 85% of the captured carbon was retained in solution, that is, it did not degas or precipitate. Thus, above-ground CO<sub>2</sub> hydration and mineral carbonate scrubbing may provide a relatively simple point-source CO<sub>2</sub> capture and storage scheme at coastal locations. Such low-tech CO<sub>2</sub> mitigation could be especially relevant for retrofitting to existing power plants and for deployment in the developing world, the primary source of future CO<sub>2</sub> emissions. Addition of the resulting alkaline solution to the ocean may benefit marine ecosystems that are currently threatened by acidification, while also allowing the utilization of the vast potential of the sea to safely sequester anthropogenic carbon. This approach in essence hastens Nature’s own very effective but slow CO<sub>2</sub> mitigation process; carbonate mineral weathering is a major consumer of excess atmospheric CO<sub>2</sub> and ocean acidity on geologic times scales.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"CO<sub>2</sub> mitigation via capture and chemical conversion in seawater","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-15 01:33:26.100364","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2021-04-08","DateCreate":"2020-10-01","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000286577100038","VABBcode":null,"OpenAcc":0,"DOI":"10.1021/es102671x"},"refs":null,"anarec":{"AnaID":329744,"PubliDate":2011,"Pagination":"1088-1092","XtraPublOfAnaID":null,"ISBN":null,"Volume":"45","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42837,"SerRR":"Environmental Science and Technology.
