An article in Fortune (Oct 17,2011) describes the mismatch between demand for CO2, its indequate supply in pure form, but its prevalence in the air.  Demand for CO2 is from soda manufacturers to make bubbles, greenhouse gases to speed plant growth, dry ice manufacturers and liquid CO2 manufacturers. In addition, enhanced oil recovery uses CO2 to extract stranded oil in reservoirs.  Possible supply plans include capturing CO2 from the atmosphere, using chemicals to separate the CO2 and thus generating supply. Will a closed loop solution to recover CO2 dispersed into the air decrease use of new fossil fuels while maintaining industrial activity? Should such technologies be funded by cap and trade agreements? How Should the effluents from such recovery plants be regulated to ensure that the overall supply chain is more benign than current alternatives?
