Tech Bet Could Slow Climate Change

That is why ADM has partnered with the U.S. Department of Energy to bury some of that CO2 in a saltwater aquifer that fills porous rock 7,000 feet below the facility. If all the brewery's CO2 could be stored in this way, the ethanol could become a biofuel to burn, one that actually reduces the amount of CO2 in the air and that seems to be one of the last hopes on offer to keep global warming below 2 degrees Celsius.
