What is carbon capture and sequestration?
There are two separate parts to CCS – the “capturing” process whereby carbon emissions are prevented from being released into the air, and the “sequestration” or “storage” of the captured carbon. “Capturing” carbon means separating out the carbon dioxide from all of the other gases and particulates often found in fossil fuel exhaust. Once you’ve gotten a relatively pure carbon stream you’ve got to find somewhere to store it, “permanently.” This is the type of “permanent” we talk about when we look for places to store toxic waste.
