Alternative Energy Fundamentals -EGE3903
Energy systems play a critical role in everyday life, and as such are an important part of engineering. This course serves as an introductory course in alternative energy. By using historical traditional energy generation methods and by reviewing typical energy consumption patterns key concepts, terminology, definitions, and nomenclature common to all energy systems are introduced. An overview of the major fuels and their energy content is also presented. The pending environmental and economic consequences of using these mature (and typically fossil fuel based) energy generation technologies along with the concepts of sustainability provide the basis for the consideration of alternative energy systems.
After a basic understanding of energy systems has been laid the core component of this course begins. A brief introduction to atmospheric science and weather provides a foundation for the study of wind and solar energy systems. Wind and solar energy maps from the National Renewable Energy Laboratories are evaluated. Students are provided broad insight into the energy content of wind, the Betz limit, and the design and control of wind turbines. The electromagnetic spectrum and solar light are introduced. The basic science of solar energy in photovoltaic and thermal systems is presented.
The nature of biomass and biofuels are also presented. A brief review of organic chemistry provides students with an understanding of these bio-sources of fuel and their energy content. Methods of energy extraction from biomass sources including gasification, pyrolysis, anaerobic digestion, biogas, landfills and fermentation are discussed. Energy from agricultural residues and municipal solid wastes, as well as ethanol, vegetable oils and bio-diesel are also addressed.
Other sources of energy are also evaluated. Use of geothermal energy is rapidly growing in the United States. The Carnot thermodynamic cycle and using the earth as a heat engine are reviewed. Natural geothermal sources, as well as building integrated technologies are evaluated. Tidal and wave energy technologies are also considered and assessed.
Fuel cells and the hydrogen economy is the last alternative energy technology reviewed in the course. The basic science of fuel cells, the various types of fuel cells, and their operation is presented. The need for fuel reforming and fuel processing is also evaluated, and the common methods for fuel reforming are considered. Hydrogen generation, handling and storage are evaluated, along with the needed safety codes.
The course concludes with a general review of how to integrate these technologies into a system providing a continuous uninterrupted power stream. A short power electronics portion of the course covers the major electrical equipment required for power transmission and power conditioning.
This course investigates the standard power converter topologies using cycle-by-cycle averaging to model the power electronics. The course includes the study of ac to dc power supplies such as are used in personal computers and other electronic devices, dc to dc converters such as are used in automotive and other battery-powered applications, and dc to ac converters such as are used in the speed control of electric motors and in power inverters used to produce 110V ac from the battery of an automobile. The course studies the component building blocks of power electronic circuits as well as design strategies and design considerations. The course includes a brief introduction to the design of magnetic components.
This is course allows a Student to work one-on-one, or in a small group of like-minded students on a specific project, with an engineering faculty member in a self-directed manor to study specific areas of interest in the field of Alternative Energy.
The Student will discuss the proposed Directed Study with a faculty member who may agree to act as Advisor (or the Department Chairman). When a topic and Advisor have been determined, the student and Advisor will fill out a Directed Study request from with a detailed plan of work attached. The Directed Study form essentially sets up a contract between the Student and the Advisor and is signed by both. It lists a specific set of activities will be completed by the Student within the required time window for the Directed Study activities. The time window is one academic semester. The Student will submit the required from and the work plan to the Department Chairman who will have the final decision on acceptance of the proposal.
Typically, undergraduate students selecting the Directed Study option in Alternative Energy will have a minimum cumulative GPA of 3.25, but for certain projects a higher GPA may be required. This variable credit course allows the Student to select the level of time and number of credits they wish to expend in this effort over the semester. It is expected that students will work on their Directed Study effort at least four to five hours per week per credit hour selected. Note that this is in addition to any regular meetings the Student may have with their Directed Study faculty advisor. As the Student selects more credits there will also be a corresponding expectation of higher work effort from the Student by the Advisor. A student selecting three credits should expect to devote at least fifteen hours per week to their Directed Study activity.
Each student undertaking Directed Study in Alternative Energy is required to write a final report that is due on the last formal class day of the semester, and to also give a public oral presentation of their work on a pre-set and mutually agreed upon date between the Advisor and the Student.
This graduate course (open to Undergraduate Seniors in Engineering) reviews the science and engineering of fuel cells and fuel processors, the generation of hydrogen and its safe handling and storage. The course provides a brief overview and introduction to the history and background of fuel cells. The fundamental chemistry and electrochemistry principles are addressed early and lay the foundations of understanding for the duration of the course. Half-cell reactions, the Nernst equation, the operating electrochemical thermodynamics, along with the Butler-Volmer equation and Tafel plots are explored. The major types of fuel cells are reviewed, and their basic designs and their key components are discussed, including ionic conducting materials, electrodes, membrane-electrode assemblies (MEA), gas diffusion layers, manifolds, and bipolar plates.
The operation and performance of fuel cells are assessed and the various contributing components to over-potential losses in the polarization and power curves are considered. Fuel cell systems are then discussed, including humidification, cooling, fuel and oxygen introduction, and controls. Possible methods of system modeling are reviewed.
To address the major question “where will the hydrogen come from?” the topic of fuel reforming, and the challenges of processing gasoline, diesel, natural gas, and other hydro-carbon fuels are evaluated. Other forms of hydrogen generation, including electrolysis, are analyzed and assessed. The storage, handling and safety, and the use of hydrogen as a viable energy carrier are also topics. Lastly, the evaluation of fuel cells and their efficiencies as integrated systems are assessed.
Several additional references from a variety of recent technical journals relating to fuel cells, their performance and hydrogen systems will be introduced and reviewed by students to supplement the learning process.
This graduate course (open to Undergraduate Seniors in Engineering) reviews the science and engineering of solar and wind energy generation power systems. Initial topics include an introduction to atmospheric science, weather conditions, the seasonal nature of sunlight and solar tracking, and the origins of wind and the influences of ground topography on wind conditions. A comprehensive review of Solar and Wind energy maps provide the student an understanding of the general opportunities available for applying these renewable energy systems.
