Not mentioned in these comments is the actual method they cite in capturing the solid CO2. The method involves bubbling CO2 through water and hydrogen sulfide, which is incredibly toxic. Not sure if there's a better way to do it, but their current process is both economically infeasible and dangerous.

I don't think 'incredibly toxic' is the best word for a smell most people are familiar with.
Industry uses toxic chemicals all the time. It's not a big deal. This is a chemical that's relatively easy to notice and where prolonged non-acute exposure doesn't have known harms. It's better than most.
