Estimating Oil Concentration And Flow Rate With Calibrated Vessel-Mounted Acoustic Echo Sounders, Thomas C. Weber, Alex De Robertis, Shep Smith, Samuel F. Greenaway, Larry A. Mayer, Glen Rice

Center for Coastal and Ocean Mapping

As part of a larger program aimed at evaluating acoustic techniques for mapping the distribution of subsurface oil and gas associated with the Deepwater Horizon-Macondo oil spill, observations were made on June 24 and 25, 2010 using vessel-mounted calibrated single-beam echo sounders on the National Oceanic and Atmospheric Administration ship Thomas Jefferson. Coincident with visual observations of oil at the sea surface, the 200-kHz echo sounder showed anomalously high-volume scattering strength in the upper 200 m on the western side of the wellhead, more than 100 times higher than the surrounding waters at 1,800-m distance from the wellhead, …

A Gis Approach For Estimating Optimal Sites For Grid-Connected Photovoltaic (Pv) Cells In Nebraska, Tomotoshi Funabashi

Department of Environmental Studies: Undergraduate Student Theses

In the context of rising energy concerns and increased spotlight on solar energy, this study examines and draws attention to the state of mid potential sunlight. The purpose of this study is to estimate the optimal sites for grid-connected photovoltaic cells in Nebraska, which is ranked 13th nationally in terms of insolation potential. Five factors – insolation potential, adjacency to roads, accessibility to grid, topography, and acreage – are examined with the use of Geographic Information System (GIS). Insolation potential was quantitatively analyzed by averaging, plotting, and interpolating the 20 years of datasets recoded at 28 weather stations of High …

In The Realm Of Supay: The Stories Of The Miners, Graham Sutherland

Independent Study Project (ISP) Collection

Ah, El Cerro Rico. She’s beautiful, no? Looming over Potosí with her red-tinted earth. But her real beauty is hidden within. Her body filled with veins of silver, the very silver that shimmered in the eyes of the Spanish empire and made Potosí one of the largest cities in the world. Oh, and the tin, the tin that helped Simon Patiño own mansions on 3 continents, living in villas in the United States and France while the ones here in Bolivia only collected dust. Mineral wealth you wouldn’t believe. They say that the Cerro Rico has twelve polleras of riches, …

Variable Renewable Energy In Modeling Climate Change Mitigation Scenarios, Falko Ueckerdt, Robert J. Brecha, Gunnar Luderer, Patrick Sullivan, Eva Schmid, Nico Bauer, Diana Böttger

Physics Faculty Publications

This paper addresses the issue of how to account for short‐term temporal variability of renewable energy sources and power demand in long‐term climate change mitigation scenarios in energy‐economic models. An approach that captures in a stylized way the major challenges to the integration of variable renewable energy sources into power systems has been developed. As a first application this approach has been introduced to REMIND‐D, a hybrid energy‐economy model of Germany. An approximation of the residual load duration curve is implemented. The approximating function endogenously changes depending on the penetration and mix of variable renewable power. The approach can thus …

An Energy Use And Emissions Inventory, Mark A. Gathany, Robert Chasnov

Science and Mathematics Faculty Presentations

Maintaining a 400-acre campus which supports the education of 3000 students requires energy. Data were gathered from across campus as part of a faculty research project and in conjunction with an undergraduate course. The project was initiated in order to develop an energy usage and emissions inventory for the University while at the same offering students exposure to the process. Inventory inputs included stationary consumption (burning of natural gas to supply heat), electricity purchased, campus vehicle usage (gasoline consumption), commuter vehicle usage (faculty and staff only), and transportation and distribution (T&D) expenses. Whereas the student population has increased by only …

Cutting Away From The Power Grid, Robert Chasnov, Mark A. Gathany

Science and Mathematics Faculty Presentations

One of the course objectives for the junior-level Thermodynamics course being taught to our mechanical engineering (ME) majors is “students will analyze engineering systems to evaluate their thermodynamic designs”. The Rankine Cycle and its application to power plants were studied intensely. Students were provided with the results of the campus Energy Usage and Emissions Inventory. Some key data which they noted was (1) 74% of the campus energy usage was electricity purchased from the local distributor (2007), (2) roughly 90% of the campus energy usage over the past 10 years was attributed to either purchased electricity or purchased natural gas, …

Logistic Curves, Extraction Costs And The Effective Size Of Oil Resources, Robert J. Brecha

Physics Faculty Publications

The size of potential fossil fuel resources is an issue of perennial interest and controversy. Fundamentally, there appears to be a conflict in interpretation of available data for both past and future extraction histories. As fossil-fuel prices rose dramatically over the past several years, the question of resources once again became acute. In this paper we concentrate on conventional and non-conventional oil resources and make four main points, with the overarching theme that one can determine an effective oil resource that represents significantly less availability for consumption than usually posited by tallying resources in place.

First, looking at oil production …

Hong Kong, with a large, dense population that uses a vast amount of energy, has become China’s epicenter of trade and economic development. Currently, Hong Kong relies on nuclear power and fossil fuels for most of its energy needs. The growing concern of global climate change and the depletion of traditional fuel reserves inspired me to investigate the green technologies that have the potential to replace or supplement current energy sources.

The purpose of my project is to provide an informative and interesting assessment of …

Prioritizing Investment In Residential Energy Efficiency And Renewable Energy: A Case Study For The U.S. Midwest, Robert J. Brecha, Austin Mitchell, Kevin P. Hallinan, J. Kelly Kissock

Physics Faculty Publications

Residential building energy use is an important contributor to greenhouse gas emissions and in the United States represents about 20% of total energy consumption. A number of previous macro-scale studies of residential energy consumption and energy-efficiency improvements are mainly concerned with national or international aggregate potential savings. In this paper we look into the details of how a collection of specific homes in one region might reduce energy consumption and carbon emissions, with particular attention given to some practical limits to what can be achieved by upgrading the existing residential building stock. Using a simple model of residential, single-family home …

A Stochastic Model For Wind Turbine Power Quality Using A Levy Index Analysis Of Wind Velocity Data, Jonathan Blackledge, Eugene Coyle, Derek Kearney

Conference papers

The power quality of a wind turbine is determined by many factors but time-dependent variation in the wind velocity are arguably the most important. After a brief review of the statistics of typical wind speed data, a non- Gaussian model for the wind velocity is introduced that is based on a Levy distribution. It is shown how this distribution can be used to derive a stochastic fractional diusion equation for the wind velocity as a function of time whose solution is characterised by the Levy index. A Levy index numerical analysis is then performed on wind velocity data for both …

Booms And Busts: Russia And Its Oil, 1970 To 2011 And Beyond, Cliff Gaddy

Brookings Scholar Lecture Series

For 40 years Russia’s domestic economic and political development and its foreign policy ambitions have been driven by the varying fortunes of its oil and gas wealth. The story continues to play out today, with crucial global consequences. Russia remains the world’s largest producer of oil and gas. It holds the third largest foreign exchange reserves in the world. Understanding the role of Russia’s energy wealth is key to understanding what role the country may play in world energy security and geopolitics in the years ahead.

Long Term Outdoor Testing Of Low Concentration Solar Modules, Lewis Fraas, James Avery, Leonid Minkin, H. X. Huang, Tim Hebrink, Robert F. Boehm

Mechanical Engineering Faculty Research

A 1‐axis carousel tracker equipped with four 3‐sun low‐concentration mirror modules has now been under test outdoors at the University of Nevada in Las Vegas (UNLV) for three years. There are three unique features associated with this unit. First, simple linear mirrors are used to reduce the amount of expensive single crystal silicon in order to potentially lower the module cost while potentially maintaining cell efficiencies over 20% and high module efficiency. Simple linear mirrors also allow the use of a single axis tracker. Second, the azimuth carousel tracker is also unique allowing trackers to be used on commercial building …

Identification Of ‘Carbon Hot-Spots’ And Quantification 1 Of Ghg Intensities In The Biodiesel Supply Chain Using Hybrid Lca And Structural Path Analysis, Adolf Acquaye, Thomas Wiedmann, Kuishang Feng, Robert Crawford, John Barrett, Johan Kuylenstierna, Aidan Duffy, Lenny Koh, Simon Mcqueen-Mason

Articles

It is expected that biodiesel production in the EU will remain the dominant contributor as part of a 10% minimum binding target for biofuel in transportation fuel by 2020 within the 20% renewable energy target in the overall EU energy mix. Life cycle assessments (LCA) of biodiesel to evaluate its environmental impacts have, however, remained questionable, mainly because of the adoption of a traditional process analysis approach resulting in system boundary truncation and because of issues regarding the impacts of land use change and N2O emissions from fertiliser application. In this study, a hybrid LCA methodology is used to evaluate …

Measuring Progress With Normalized Energy Intensity, Nathan Lammers, J. Kelly Kissock, Brian Abels, Franc Server

Mechanical and Aerospace Engineering Faculty Publications

Energy standard ISO 50001 will require industries to quantify improvement in energy intensity to qualify for certification. This paper describes a four-step method to analyze utility billing, weather, and production data to quantify a company's normalized energy intensity over time. The method uses 3-pararameter change-point regression modeling of utility billing data against weather and production data to derive energy signature equations. The energy signature equation is driven by typical weather and production data to calculate the 'normal annual consumption', NAC, and divided by typical production to calculate 'normalized energy intensity' NEI. These steps are repeated on sequential sets of 12 …
