"Hum, what to do with the carbon monoxide? Release it, or Burn It? Seems to me the purpose of this is remove sulfur, not carbon."
See solid oxide fuel cells (SOFC). It will quite nicely utilize the CO-H2 mix. Sure, you do emit SOME carbon dioxide in the final gas, but the efficiency is far higher than combined-cycle gas turbine plants.
SOFC.....I don't get the impression that these are the fuelcells Detroit expects to use. 1000 degrees C! Pretty far out stuff. Maybe stationary applications. Same $400 per kilowatt goal that I stated in my "shallow article".
