A century’s worth of CO2 emissions can be safely stored underground
A new study by CEE Professor Ruben Juanes and graduate students Christopher MacMinn Ph.D. ’12 and Michael Szulczewski shows that there is enough capacity in deep saline aquifers in the United States to store at least a century’s worth of carbon dioxide emissions from the nation’s coal-fired powerplants. Though questions remain about the economics of systems to capture and store such gases, this study addresses a major issue that has overshadowed such proposals. It is the cover story of the April 3 issue of the Proceedings of the National Academy of Sciences. Read a news story.
