There has been overwhelming evidence that anthropogenic carbon dioxide (CO2) emissions are a major contributor to global climate change. Geological CO2 storage is widely regarded as a promising tool for reducing anthropogenic CO2 emissions into the atmosphere, which is critical in humanity’s effort to combat climate change. In geological CO2 storage, supercritical CO2 is captured from the flue gas of power plants and injected underground into deep geological formations. The videos below provide an informative overview of geological CO2 storage technologies.
