How much energy is used to:


1.        Drill a well 1.5 miles deep

2.       Convert the C02 to a liquid (is it dissolved in a carrier fluid or cryogenically condensed, article doesn’t say);

3.       Pump 100,000 tons a year into the sandstone layer?


Another way of thinking about this is:  How much CO2 is produced in sequestering CO2?  How much entropy is produced trying to capture and send back into the earth carbon that originated there in the first place – it was already sequestered before we burned it.  Stop burning it, no need to sequester.

If all goes smoothly, this week engineers will begin pumping carbon dioxide, converted to a fluid, into a layer of sandstone 7,800 feet below the rolling countryside here and then into a layer of dolomite 400 feet below that.

The liquid will squeeze into tiny pores in the rock, displacing the salty water there, and assume a shape something like a squashed football, 30 to 40 feet high and hundreds of yards long.

American Electric Power’s plan is to inject about 100,000 tons annually for two to five years, about 1.5 percent of Mountaineer’s yearly emissions of carbon dioxide. Should Congress pass a law controlling carbon dioxide emissions and the new technology proves economically feasible, the company says, it could then move to capture as much as 90 percent of the gas.
