BUT the reservoirs and aquifers are not conveniently located where  
the coal is or where we might want to put a power station. We would  
need an extensive pipeline system to distribute it to where it can be  
pumped underground which would need to more extensive than the  
existing natural gas and oil pipelines. Also CO2 is heavier that air.  
A major leak will run downhill and smother all in it's path so siting  
will be important. I certainly would not want to leave near a  
pipeline full of pressurized CO2.
