Funded by new tax credits, U.S. carbon-capture network could double global CO2 headed underground

With the right public infrastructure investment, the United States could as much as double the amount of carbon dioxide emissions currently captured and stored worldwide within the next six years, according to an analysis by Princeton University researchers.

The authors propose in the Proceedings of the National Academy of Sciences a pipeline network that would transfer carbon dioxide waste from ethanol refineries in the American Midwest — where grains are fermented to produce the alcohol-based fuel — to oil fields in West Texas. The captured carbon would then be pumped into near-depleted oil fields through a technique known as enhanced oil recovery, where the carbon dioxide helps recover residual oil while ultimately being trapped underground.
