  1. 1. NebraskaCenter forEnergySciencesResearch
  2. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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.
