Carbon capture and storage (CCS) technology is widely believed to be necessary to save the climate, but the technology is still in a fledgling state, with relatively few large-scale installations around the world. But fitting corn-ethanol refineries with carbon-storing technologies would be a winning financial proposition that could simultaneously advance the CCS industry’s growth. CCS technology can capture the tons of pure carbon dioxide that ethanol refineries spew out. In fact, one ethanol plant in Illinois with CCS technology is expected to save 1 million tons or more from entering the atmosphere each year.
