Transcript

  • 1. NebraskaCenter forEnergySciencesResearch
  • 2. NCESR Mission  Established in 2006  Collaboration between UNL and Nebraska Public Power District  To conduct energy research that produces new technologies, processes and systems that provide new or significantly enhanced energy sources and improve the quality of life and economic opportunity for Nebraskans.NCESR
  • 3. Seed grants grow energy ideas  UNL faculty compete for energy research funding  Proposals are Peer Reviewed by outside experts  Funds support innovative research and collaboration among faculty  50 research projects funded to dateNCESR
  • 4. Hydrogen Production and Storage Using Wind and Nuclear Sources  Dr. Jerry Hudgins, Electrical Engineering  Integration of power electronics sub-systems between a wind turbine and an electrolyzer, optimal tip speed control algorithms for low-power turbines, and low-cost electricity can provide the needed factors for successful realization of low- cost hydrogen production.  It is estimated that integration of the power electronics systems will reduce the hydrogen production costs by up to 7%.  Further reduction in electricity costs must come from improved electrolyzer technology and reduced electrical energy production costs by delivering electricity from unused renewable generating sources (e.g. not hydrocarbon fueled generators).NCESR
  • 5. Passive Solar Powered Earth Contact Heat Exchangers for Cooling Buildings  Dr. Bing Chen, Computer and Electronics Engineering  The goal is to develop a fully functional and optimally performing full scale demonstration of a building cooling technique which employs an earth contact heat exchanger for cooling of the building air.  The air is drawn into a building space by a passive solar driven collector-solar chimney array (through passive convection)  The project will determine the maximum earth contact cooling possible and compare to a conventional fan driven cooling system.NCESR
  • 6. A Probabilistic Framework for Determining Optimum Maintenance Strategies to Improve Reliability, Efficiency, Safety, and Cost-Effectiveness for Wind Generation Plants  Dr. Sohrab Asgarpoor, Electrical Engineering  To provide a knowledge-based maintenance management system to optimally allocate maintenance resources such that reliability of a wind farm is above a target level.  To provide a framework to evaluate the performance of wind power plants.NCESR
  • 7. Energy Storage by Supercapacitors Based on Carbon Nano-onions  Dr. Yongfeng Lu, Electrical Engineering  To develop supercapacitors of high energy density and low cost for efficient energy collection, storage, and regulation.  Carbon Nano-onions (CNOs) are used as an electrode material due to their large SSA, excellent electrical conductivity, and low cost.NCESR
  • 8. Nanostructured Low Work Function N-Electrodes for Polymer Photovoltaics  Dr. Chin Li Cheung, Chemistry  To develop nanostructured low work function electrodes for organic photovoltaic (OPV) devices (solar cells).NCESR
  • 9. Online Non-Intrusive Wind Turbine Fault Diagnosis  Dr. Wei Qiao, Electrical Engineering  To develop a new nonintrusive technology for online fault diagnosis of wind turbine gearboxes and rotors/shafts.NCESR
  • 10. Investigating Wind Turbine Safety and Reliability  Dr. Michael Riley, Industrial and Management Systems Engineering • To perform a comprehensive safety analysis of electrical generation windmill work zones to identify potential workplace hazards • Identify all sources of energy (electrical, mechanical, chemical, and biological) that a worker could encounter in the windmill work zone • Determine if the exposures to sources of energy are unreasonably dangerous • Complete a demonstration project and use a systematic approach to select best safety practices to eliminate or minimize fallsNCESR
  • 11. Development of an Inexpensive Manufacturing Method for High Efficiency Solar Cells  Dr. Rodney Soukup, Electrical Engineering  The goal of this research project is to develop a non-vacuum technique which can be used to produce high efficiency solar cells at relatively low cost. This type PV material has been shown to be up to 20% efficient.
