To prevent global warming, researchers and policymakers are exploring a variety of options to significantly cut the amount of carbon dioxide that reaches the atmosphere. One possible approach involves capturing greenhouse gases such as carbon dioxide at the source — an electric power plant, for example — and then injecting them underground. While theoretically promising, the technique has never been tested in a full-scale industrial operation. But now MIT engineers have come up with a new software tool to determine how much CO2 can be sequestered safely in geological formations. Ruben Juanes, assistant professor of civil and environmental engineering, and co-author CEE graduate student Michael L. Szulczewski reported this work Nov. 18 at the 9th International Conference on Greenhouse Gas Control Technologies (GHGT-9), held Nov. 16-20 in Washington, D.C. Read more.
