Citations: 2002 Stephen Dabkowski The Age (Melbourne, Australia) (Jan. 25) “Plan For $5b ‘super Plant’ In Coal Fields”: Its plans are believed to include reducing greenhouse gases from the project by using geosequestration technology. The process involves pumping carbon dioxide underground into reservoirs that have been tested to ensure against gas leakage. 2004 Stephen Cauchi The Age (Melbourne, Australia) (June 16) “Advocates pump up greenhouse storage”: The nightmare scenario for geosequestration—also known as geostorage—occurred in Africa in 1986. In the dark of night, Lake Nyos in Cameroon emitted a huge cloud of carbon dioxide. The gas, which is heavier than air, settled in a thick layer over the surrounding area, asphyxiating 1800 people and countless animals. Geostorage is a seemingly sensible idea—trap polluting gases from power plants, compress them until they are liquid and pump them underground. No more greenhouse gases trapping heat in the atmosphere and, therefore, no global warming.
