Gorgon Carbon Dioxide Injection Project

Gorgon Carbon Dioxide Injection Project wani bangare ne na Gorgon Project, daya daga cikin manyan ayyukan iskar gas a duniya. Shirin Gorgon, wanda ke kan Tsibirin Barrow a Yammacin Ostiraliya, ya haɗa da masana'antar iskar gas (LNG), masana'antar gas ta cikin gida, da kuma aikin Injection na Carbon Dioxide.https://www.bbc.com/hausa/multimedia/2013/05/130510_senegal_fishing

An fara allurar carbon dioxide a cikin 2019.  Da zarar yana aiki da cikakken ƙarfin aiki, Gorgon Carbon Dioxide Injection Project zai zama tashar allurar CO 2 mafi girma a duniya, tare da ikon adana har zuwa tan miliyan 4 na CO 2 a kowace shekara - kusan tan miliyan 120 akan rayuwar aikin, da kashi 40 cikin ɗari na jimlar Gorgon.

Wannan aikin, wanda Chevron ya jagoranta, an tsara shi don kama 3.5 Mt na carbon dioxide a kowace shekara daga filayen gas na Greater Gorgon kuma adana shi a cikin tsarin Dupuy a ƙarƙashin Tsibirin Barrow. Bayan kammala, aikin zai zama aikin da ya fi girma a duniya.
