A bold undertaking to store one million metric tonnes (1.1 million short tons) of carbon dioxide in a sandstone reservoir 1.3 miles (2.1 km) below Decatur, Illinois, is well under way. The project began last November, and has so far injected more than 75,000 tons of carbon dioxide, almost one tenth of the target. The University of Illinois, which is leading the Illinois Basin - Decatur Project (IBDP), hopes that the scheme will demonstrate the safety and effectiveness of carbon sequestration, as well as raise public awareness of the process's potential environmental benefits.
