Marcellus Shale and other natural gas plays are considered valuable for what can be extracted from them, but what if they could also be valuable and environmentally helpful after they are been depleted?
That is a question Penn State faculty are looking at as part of a research project the National Energy Technology Lab's Regional University Alliance is conducting. Seth Blumsack, John T. Ryan Jr. Faculty Fellow, and Turgay Ertekin, head of the Department of Energy and Mineral Engineering and holder of the George E. Trimble Chair in Earth and Mineral Sciences, are part of the group studying whether it would be possible and make economic sense to capture carbon dioxide produced at large point sources and pump it into existing natural gas wells. <Penn State News.>
