  •  Carbon Capture and Storage is being developed (1+ / 0-)

    and tested as a mitigation strategy that could help us with power plant carbon emissions.  Here's a video that a professor friend gave to me on "Carbon Capture and Storage: A bridge to a low carbon future" by Shell.

    The bad thing about CCS is that it just means that fossil fuel industries can keep polluting longer.

    Solar has come down so much in cost that in America, it can pay for itself within a few years time.  If you live in a hot area, like Florida or California, it makes sense as the cost of electricity is expected to rise every year.

      But I reced you for recognizing that we have grid parity in much of the US for rooftop solar. I am trying to explain this to Kossacks, and I don't see any sign that I am getting through.

      Within a few years, it will become impossible to get construction funding for coal-fired power plants. Oil will take somewhat longer, and gas will continue as long as we need rapid response capacity and don't have good storage options for renewable power. Maybe another ten years, according to what I read.

      •  CCS works (0+ / 0-)

        It's also known as planting a tree.  A few trillion of them would make a significant difference in the planet's ecology.  Besides pulling CO2 out of the atmosphere, they could increase cloud cover by their transpiration of water.  That in turn would whiten the planet, reflecting more of the sun's radiation back into space.  

        But as far as propaganda about CCS, I don't see it.  The millions of acres of North American forest destroyed by the pine bark beetle aren't being replanted, neither is there a program running to convert them to biochar and bury it before they rot or burn naturally.  

        Now if by CCS you mean attaching a huge suction wand to a power plant and trying to inject it underground, that indeed is propaganda and bullshit.

      •  Agreed. But, given that the video was made by (0+ / 0-)

        Shell it has intrinsic value as some Americans actually believe that anthropogenic global warming is a hoax.

        Keeping the fossil fuels in the ground and converting to clean energy is the best solution.

        The other issue with fracking and CCS is the long term isolation concept (the idea that you can effectively seal off leaks to the water table or atmosphere permanently);  in my opinion, it is flawed from the outset.  It's like saying that we can leave poisonous or radioactive tubes going a mile or so into the earth with an inch of cement around them won't ever fail?  BTW, what do we do to the millions of acres with frack wells all over the place when we want to use that land for something else?  Who gets to remove, dig up and clean up those wells and pools of toxic mess that lie below?  What happens if something disturbs the earth where the dangerous chemicals are supposedly, isolated, and releases large quantities into the water table?

        What happens when water is contaminated and food producers or human users don't know that they are being exposed?  

        I have read that the cement job of the well and the composition of the cement used are not even regulated.

      •  Here's a new IMB project that can produce much (0+ / 0-)

        more solar power for the money and also use the heat to desalinate water.  This may be a good prototype for areas where fresh water supplies are inadequate or being impacted by rising sea water.
