Carbon capture from power plants would contain a mixture of CO2, NOx and SOx, and very few projects (see article) have ever attempted to capture this corrosive mixture, on an industrial scale, for a very long time. It is quite a complicated and energy-intensive process (collect the gases, compress/liquify/make supercritical, transport, convert P/V/T again, pump it down). I know that the Norwegians (or perhaps various multinationals) have been doing this for decades, capturing CO2 at the source, at the Sleipner giant oil field in the North sea . But that is not a power plant.
