The study I refer to didn't actually say that carbon capture makes things worse. But that is the only conclusion one can draw given that the capturing is done for the purpose of dramatically lengthening the life of oil wells that would otherwise close, according to a recent piece in DeSmog. The oil wells in question are in Saskatchewan and were scheduled to close in 2016. Now with carbon dioxide pumping into them, they could produce oil for somewhere between 39 and 84 more years.
So the project's boondoggle credentials are now certified. Public money is being 'invested' in this research. But, of course, what seals the deal is that the project's purpose is to produce more fossils fuels to replace at least indirectly the ones originally burned to make the now injected carbon dioxide. That creates an opportunity to emit more carbon dioxide that, in turn, needs to be extracted from the air using more boondoggle machines like those nifty extractors in Iceland.
