Energy: the Next Fifty Years

Energy is basic to human society, like food, shelter, communication, and mobility. A new international energy landscape is emerging as developing countries create their energy infrastructures and as energy technologies move away from fossil toward more sustainable sources and uses. The 50-year time scale for significant change to the energy landscape implies that the strategic research and development choices we make now ill determine future energy and societal outcomes. The promising opportunities for science and technology discovery and development in energy will be analyzed in the context of vibrant, interactive and rapidly advancing national and global societies.

High Temperature Superconductivity: Taming Serendipity

A century after the discovery of superconductivity, the design of new and more useful superconductors remains enigmatic. High-temperature super-conductors offer unique solutions to fundamental grid challenges of the 21st century and hold great promise in addressing global energy challenges in energy production, storage, and distribution. Traditionally guided by serendipity, researchers now endeavor to design new superconductors predictively. Advanced experimental techniques, such as point contact spectroscopy measurements, aid in identifying promising candidates.

Looking at Chemistry in Hard to See Places: Understanding Energy Conversion at 1400° Celsius

Solid oxide fuel cells (SOFCs) are promising devices for stationary and portable power and heat generation, because they can use complex fuels such as hydro-carbons, CO, and alcohols. Extreme, non-equilibrium conditions and high tem-peratures (≥ 700 ˚C) required for SOFC operation hamper efforts to understand the mechanisms of component degradation in SOFCs. This talk focuses on new insights into SOFC chemistry and the conversion of carbon-containing fuels (both hydrocarbons and oxygenated) into electricity, carbon dioxide and water, gleaned from a combination of techniques including electrochemical impedance spectroscopy, voltammetry, and vibrational Raman scattering.
