"This demands a more robust marketplace beyond CO2 for soda and oil wells." The only permanent solution is sequestering the carbon deep underground (depleted oil/gas fields or saline aquifers). Most CO2 "utilization" cases (including production of biofuels) merely delay the inevitable release of the gas into the atmosphere. Sequestering CO2 for the sake of sequestering it does not pay though. In order for this to make sense, a carbon tax would likely have to be imposed (it worked in Norway, where Statoil has stored excess CO2 geologically for almost two decades now at the Sleipner field).
