Dra. Shirley Meng received her Ph.D. in Advance Materials for Micro & Nano Systems from the Singapore-MIT Alliance in 2005, after which she worked as a postdoc research fellow and became a research scientist in Massachusetts Institute of Technology before joining University of Florida, Department of Materials Science & Engineering as a junior faculty member. She is currently a faculty member in the Department of NanoEngineering, University of California San Diego (UCSD). Meng’s research focuses on the direct integration of experimental techniques with first principles computation modeling for developing new materials for electrochemical energy storage and conversion. She won the Materials Research Society Graduate Student Award in 2003 for her pioneering work on designing new high energy electrode materials for lithium ion batteries from first principles. She recently received the National Science Foundation (NSF) CAREER award and her research group - Laboratory for Energy Storage and Conversion (LESC) focuses on functional nano-structured materials for energy storage and conversion. Recent programs include the design, synthesis, processing, and in situ characterization of mixed transition metal oxides as high energy density electrode materials in advanced lithium ion batteries; new intercalation materials for sodium ion batteries and advanced soluble lead flow batteries for grids large scale storage.

Description: Summary: Transitioning to a sustainable low-carbon energy system poses one of the great challenges of the 21st century. The Energy Innovation Series brings leaders from government, law, finance, industry, and academia to discuss key aspects of this challenge and some of the innovative approaches and solutions being fashioned across a range of sectors. During academic year 2012-13, the series will focus on the changing energy mix in the United States and abroad, the implications of shale gas on the electric power sector, financing for energy innovation, the changing utility business model, and pathways to scale for renewable energy. This half-day conference will explore some of the dramatic changes taking place in the energy sector, with particular attentions to the U.S. electric power sector. « Hide Authors: Lance Astrella, William Boyd, Jeff Logan, John Mork
Energy Efficiency In Buildings And Heat Supply Solutions: A German Perspective For The Nuclear Shutdown
Description: Beginning with some background information on the unique German position regarding the energy supply eliminating any nuclear power by 2022 but enforcing the use of renewable energy sources, the challenges for both the building and the power generation sector will be highlighted. The talk will introduce opportunities to improve energy performance of buildings by new and innovative HVAC concepts as well as for increasing the penetration of renewable and environmental energy sources for heat and power supply in cities. That is also why a particular focus will be on other relevant aspects as multi-level district heating, combined heat and power generation and the proper balance between large-scale energy generation in heat and power plants and distributed small-scale heat and power generation in buildings in terms of a global optimum in energy use and emissions. Currently ongoing research projects at the Technical University of Dresden will be presented. « Hide Authors: Clemens Felsmann
Summary: The wind turbine drive‐train is an integral part of the turbine that converts rotational kinetic energy from the wind to electrical energy. Ensuring reliable and robust operation of the drive‐train necessitates developing an accurate dynamic response model that includes its aero‐dynamic interaction with the wind, torsional and translational responses of its mechanical components, as well as electro‐mechanical interaction at the generator. This presentation will describe a high‐fidelity lumped mass model of the wind turbine drive‐train, which is integrated with FAST, an openly available aero‐elastic code developed by the National Renewable Energy Laboratory (NREL). Jaspreet Singh Dhupia is an Assistant Professor at Nanyang Technological University, Singapore since July 2008. Prior to that, Prof. Dhupia graduated with a PhD and MS in Mechanical Engineering from the University of Michigan, Ann Arbor, and a B.Tech. from Indian Institute of Technology, Delhi. His doctoral research was carried out at the Center for Reconfigurable Manufacturing Systems funded by National Science Foundation. Currently, his research activities are funded by several government and industrial organizations in Singapore, which include the Ministry of Education, Maritime Port Authority, Rolls-Royce Singapore Pte. Ltd., and ABB Singapore Pte. Ltd. His research focuses on drive-train controls, monitoring, and modeling for different applications, such as ships, aircraft, and wind turbines.
Sustainable energy generation is one of the most urgent challenges that mankind is facing nowadays. Many countries have set ambitious objectives to increase the share of energy produced from clean and renewable sources. Unfortunately, the actual renewables are still not competitive with respect to fossil fuels, due to the high costs of the related technologies, their variable and non-uniform availability and their low power density per unit area.
