Contained and used in the process.
Not true! This process produces just as much CO2 (or maybe even a bit more) as every other power plant. The only thing gained is that the CO2 from this process winds up separated from the rest of the gasses that are produced.
It's a pipe dream to think they can "sell" the CO2. If there were a market for all the CO2 produced by power plants today, someone would already be extracting and selling it. With electric cars and heating, there would be many times more CO2 produced, as well.
