Environmental Fellows

Duke Energy Progress Graduate Fellows

Adam Alman Alan Alman
Adam is currently working toward a doctorate in the Department of Chemistry. He will study polymer-based solar cells incorporating various types of nanoparticles. Unlike commercial silicon cells, this class of devices is able to be manufactured using roll processing and printing, and has the potential to be extremely inexpensive.
Evan Johnson Evan Johnson
Evan began working as a Ph.D. student in Public Policy at the University of North Carolina in August of 2011. As a Duke Energy Progress Fellow, he will continue to develop an interdisciplinary social science research program examining the environmental policy implications of energy behavior. His work aims to identify economic, as well as social, cultural, and attitudinal drivers of conservation,efficiency, and renewable energy practices. His chief empirical interests include the impact of social capital and norms on energy behavior, as well as barriers to economically efficient energy investments among firms, organizations, and households.
Eric Rountree Eric Rountree
In the process of trying to find alternatives to fossil fuels to satisfy our energy needs, it has been suggested that the most viable source of energy is the radiation that we receive from the sun each day. One of the challenges that we must overcome if we wish to make this a practical consideration is how to deal with the fact that our times of largest energy consumption occur after the sun has set and will no longer be providing power. It is this challenge that my pre-doctoral research in the Department of Chemistry aims to overcome through the creation and testing of a molecular catalyst that can convert the sun's energy into a fuel source, such as hydrogen or methane, which can not only be used to power the grid after sunset, but can also be used to provide fuel for our increasing transportation needs.

Under my Duke Energy Progress graduate fellowship, I will be examining the physics involved when supercritical carbon dioxide is injected into the subsurface for the purpose of long-term storage. Using modern averaging theory, a precise formulation of a closed set of partial differential equations will be developed and solved using higher order methods in time and discontinuous Galerkin methods. The resultant model will be validated by comparison to very large scale computations based on the solution of microscale equations known to describe the physics for cases in which the pore morphology and topology is known.
