Are you picturing some scenario like: a natural-gas fired turbine plant captures CO2 with an amine stripper, that CO2 is then fed into a bioreactor to produce, say, Ethanol?
It seems to me that the energy content of the Ethanol isn't too different from the natural gas going into the plant so I don't see how you get ahead doing this... If you've got to add extra energy or divert some of the input energy to make hydrogen to fuel the reactor how do you end up ahead?
