    It never even occurred to me that carbon capture might be storing a giant tank of gaseous carbon dioxide. I assumed that it meant chemically reacting the carbon into some kind of solid material which was then discarded as waste, because trying to store huge chambers full of gaseous CO2 at a scale that can impact climate change is clinically insane.

      There are methods to solid capture, similar to what happens over millennia naturally. It takes a lot of energy and more importantly, water flow, and like everything else can’t possibly scale up to get enough of a percentage in the air and oceans to make a difference. It also probably has its own waste, as it’s a complex chemical process and not just one simple reaction.
