This interactive activity from NOVA scienceNOW reviews several potential means of storing carbon dioxide (CO2) captured from industrial sources. Among the featured ideas are technologies that deliver compressed CO2 to underground cavities, saline aquifers, and the deep seabed. The benefit of storing, or sequestering, captured CO2 could be significant in the fight to slow or limit global warming. However, the list of drawbacks associated with carbon sequestration includes high cost, storage capacity limitations, a still-incomplete understanding of the relevant Earth systems, and uncertainty as to whether the CO2 can be safely and permanently contained.
