The Role of Unconventional Gas in the Global Energy Future

> Slides (4.31 Mb, pdf)
The transition from a fossil-energy present to an alternate-energy future will span many decades and involves interplay among energy, environment, economy, and policy. Today, fossil fuels represent 87% of the global energy mix. Ironically, the foundation of the bridge to a lower carbon energy future will be built with fossil fuels, and natural gas will play a growing role. As existing and new conventional natural gas reserves decline, unconventional natural gas resources--shale gas, coal bed methane, tight gas and perhaps eventually natural gas hydrates--will represent a vital part of the fossil energy mix. Economic extraction of unconventional gas will be enhanced by industry-government-academic partnerships.

Dr. Scott W. Tinker is the Director of the Bureau of Economic Geology, the State Geologist of Texas, a Professor holding the Allday Endowed Chair in the Jackson School of Geosciences at The University of Texas at Austin, and the Director of the Advanced Energy Consortium. Scott is Past President of the American Association of Petroleum Geologists (AAPG) and the Association of American State Geologists. He spent 17 years in the oil and gas industry prior to joining UT in 2000. Tinker has been a Distinguished Lecturer for the Society of Petroleum Engineers and twice for AAPG. Scott holds appointments on the National Petroleum Council, National Research Council Board of Energy and Environmental Systems, and the Interstate Oil and Gas Compact Commission.

Understanding the nature of O-H bonds as the key issue in the study of water and energy: A molecular picture of water structure and dynamics from computer simulation

Computer simulations are used to study the unusual structure and dynamics of water at molecular scale. Based on ab initio density functional theory, we have calculated prototype water structures including monomers, clusters, one-dimensional chains, and overlayers on metal (Pt, Ru, Rh, Pd, and Au) surfaces [1]. The structure, energetics, and vibrational spectra, are all obtained and compared with available experiments. A general model has been developed regarding the water-surface interaction and the interwater hydrogen bonding, which gives the right wetting order of these metal surfaces. This study is further extended to silica surface, where a two-dimensional tessellation ice is observed [2]. The new configuration is stable up to room temperature, because all the water molecules are fully saturated with H bonds either to each other or to the surface hydroxyl groups. Furthermore, the solvation and dissolution dynamics of a NaCl nanocrystal in water as well as the early stage of NaCl nucleation in supersaturated solution have been studied by molecular dynamics simulation [3]. Finally, if time allows, I will discuss surface energy and surface proton order of ice Ih [4]. Our results will show you that ice surface is unexpectedly cold.

Short Bio:
Prof. Enge Wang, Co-Director of Beijing National Laboratory for Condensed Matter Physics, was selected as the first GCEP Visiting Scholar.

Prof. Wang’s current research focuses on surface physics in which he uses a combination of atomistic simulation and experimental techniques to study nonequilibrium growth, chemical vapor deposition of light-element nanomaterials, and water behavior in confined systems.
