Who consumes it, anyhow? What is it useful for? Can it simply be stored somewhere in mostly inert form? Can we pour it into a cave or a fracking hole or something and just let it be? Or does it turn back into a gas and escape?
Injected CO2 is also highly effective at sweeping stored oil and gas out of the reservoir to (ironically) help you produce more oil and gas. My company uses CO2 extensively in its older fields in the Permian Basin.
there are lots of uses for concentrated CO2. A few current uses include dry ice (shipping vaccines or other medical supplies), green houses, concrete, beverage carbonization, pumping it under ground into depleted oil wells for permanent storage, and refrigeration cycles.
There are also a lot of technologies in progress to use CO2, such as turning it right back into synthetic fuels!
The list goes on and seems to be growing by the day.
