    but getting rid of CO2 emissions, which are also now required to be controlled for new plants under the Clean Air Act, is rather harder.  That basically does require getting rid of coal plants.

    But yes, mercury, SO2 and NOx scrubbers can be dramatically effective.  This is really a story of the hazards of grandfathering

      Nope....not necessarily.  

      Best Available Control Technology determinations for coal combustion doesn't necessarily mean no use of coal under the BACT provisions of the Clean Air Act.   It may mean, however, that a facility will have to do cogeneration, it could mean the facility will use gasification techniques and CO2 sequestration.

        There are some spiffy bells and whistles one can add, although I think the notion is that it is expensive for a coal plant to measure the performance of a natural gas plant (or a solar one for that matter).  BUt in principle, there are also improvements that are theorectically possible.

        is rather harder than scrubbing mercury, SO2 and NOx. (Feel free to correct me if I'm wrong here, but I don't think I am.)

        Let us all have the strength to see the humanity in our enemies, and the courage to let them see the humanity in ourselves.

        •  Co2 sequestration isn't that hard (0+ / 0-)

          just real spendy, in the hundreds of millions.  In Texas, however, you can sell the CO2 for around 20 bucks a ton, so a coal plant could make another $80 million/year before expenses in CO2 sales.

          Orly, it isn't evidence just because you downloaded it from the internet.

      •  The new source performance standard for power (0+ / 0-)

        plants of 1000 lb of CO2/Megawatt/hour can't be met by cogeneration alone, only gasification and sequesteration will do it, and those add 100s of millions to the plant cost for installation, and 10s of millions/year for operations.
