Princeton University researchers have proposed a US pipeline network that would capture, transport and store underground up to 30 million metric tons of carbon dioxide emissions each year -- an amount equal to removing 6.5 million cars from the road. The network (thick blue line at center) would transfer carbon dioxide waste from ethanol refineries in the American Midwest (green dots) to oilfields in West Texas. Midwestern ethanol refineries, which emit 43 million metric tons of carbon dioxide annually, are currently located far from existing carbon dioxide pipelines (orange lines) and largely don't sit atop geological formations suitable for storing CO2 (beige areas).
