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.
