Underground space enough to dump 500x U.S. CO2 emissions

摘要

The solution to handling carbon dioxide emissions may lie underground. The U.S. Geological Survey (USGS) said in late June it had identified enough room underground to store more than 500 times the annual U.S. CO2 emissions. Basins throughout the country have a potential 3,000 metric gi-gatons (Gt) of capacity, most of it located in the Gulf Coast. If liquefied, CO2 emissions captured at industrial and energy plants could be injected into the reservoirs, USGS officials said. The oil and gas industry is to thank for the storage locations.
