Carbon capturing is testing

The carbon capturing thinking seems simple enough to get people’s imagination and I personally very much hope that can work.

It, however, may eventually be proven to be a fanciful thinking from existing heavy carbon emitters like coal fired power plants.

The world needs to make a concerted effort in making sure whether carbon capturing can work quickly, because investment decisions for many power plants are urgently pending on it.

How long has this technology been discussed already? How much progress has been made so far? Where or what are the difficulties or sticking point for further progress?
