Currently, they turn it into a liquid then pump it through pipelines to deep underground strata. It is called carbon sequestration. This is a significant cost. The costs of operation is what often sinks breakthrough schemes. If there is not a positive cost-benefit ratio, it never catches on. There are things one can do in a lab that turn out to be prohibitively expensive when upscaled and industrialized. Time will tell.
We already pump lots of CO2 underground. I think the biggest thing is the amount of storage needed. Next step would be to utilize CO2 better..
It's a big planet and there are plenty of suitable underground strata, but it is never right where you need it. Cost will be the major factor. I'm not sure how. We have all the CO2 that we need for industrial use. If we could make limestone out of it, it could be put to good use in construction, but the solids that they can make out of it now are unstable.
But "jumbo" is strictly a relative term, meaning that something is very large in comparison to the average. Therefore, anything can be considered "jumbo" depending on how large it is in relation to similar objects.
