What qualifies as "DAC CDR"?

There are summaries of cost estimates in several of the articles referenced in this thread. There are values reported at pretty much every stop between $45 and $1000/ton. I am not sure that I find any of the estimates convincing as yet. I wonder if the size of global demand (whether industrial or governmental) is a bigger problem than cost.
