Recent and Current Externally-Sponsored Research Projects
Title: Development and Application of Optimal Design Capability for Coal Gasification Systems
Investigators: H. Christopher Frey, Principal Investigator
Granting Agency:
Dates: 1997-2006
Brief Description: The objective of this project is to develop system analysis tools useful in evaluating energy systems and in addressing the complex problems of environmental management. This project includes the development of a guideline document describing methods for identifying and characterizing key technical and economic uncertainties which are required as inputs for stochastic modeling of energy technologies. This project will include development of new computer simulation models that shall predict the performance, emissions, and cost of advanced fossil fuel power generation and pollution control technologies specified by the U.S. Department of Energy.
Title: In-Vehicle Energy and Emissions Information System
Investigators: H. Christopher Frey and Nagui M. Rouphail
Granting Agency: National Science Foundation
Dates: January 2003 – December 2006.
Brief Description: The key objectives of this research project are to: (1) develop a micro-scale predictor of energy use and emissions that is deployable at the individual vehicle level in real-time; (2) identify, compare and evaluate alternate energy use and emissions sampling/reporting schemes that are appropriate at the vehicle and network levels; (3) Develop and test a prototype In-Vehicle Energy and Emissions Information System (IVEEIS); and (4) formulate and assess the utility of IVEEIS in developing transportation design and control measures aimed at energy and emission management policies.
Title: Life Cycle Inventory and Impact Analysis Framework for Nonroad Construction Vehicles and Equipment
Investigators: H. Christopher Frey and William Rasdorf
Granting Agency: National Science Foundation
Dates:
Brief Description: The objectives of this work are to: (1) Characterize the second-by-second in-use emissions and energy use of nonroad construction vehicles and equipment, including emissions of nitric oxide, carbon monoxide, hydrocarbons, carbon dioxide, and particulate matter, including real time sensing and monitoring where needed to fill data gaps; (2) Develop a life cycle inventory of conventional nonroad construction vehicles and equipment; and (3) Identify and recommend methods for reducing energy use, emissions, and impacts..
Title: Regional Development, Population Trend and Technology Change Impacts on Future Air Pollution Emissions
Investigators: Nagui M. Rouphail and H. Christopher Frey
Granting Agency: U.S. Environmental Protection Agency STAR grant via University of North Carolina at Chapel Hill, and Center for Transportation and the Environment
Dates: November 2004 to November 2007
Brief Description: This research tests the hypothesis that smart-growth development patterns can significantly influence the quantity and location of direct and indirect emissions from mobile sources. The patterns of interest include the type of development and its location. We will develop a general method for exploring the leverage that smart-growth development patterns have on the spatial pattern and quantity of emissions from mobile sources. We will explore scenarios and chart the envelope of the effectiveness of smart growth as a means for reducing emissions. We will determine whether substantial emissions reductions are feasible with forecasts of the market penetration of smart growth.
Title: Real World Duty Cycles and Utilization for Construction Equipment in NC
Investigators: H. Christopher Frey and William Rasdorf
Granting Agency: North Carolina Department of Transportation.
Dates: July
1, 2005 to
Brief Description: Construction vehicles contribute substantially to statewide emissions. 32 NC counties are partially or fully designated as non attainment under new air quality standards for ozone. Therefore there is a need to more accurately quantify the emissions from construction vehicles and seek opportunities to manage or reduce emissions. The goal of this study is to assess construction equipment types and uses, plan a field study, measure emissions and collect data, analyze the data and develop typical cycles, and demonstrate methods for estimating emissions for construction equipment.
Title: Best Practices Guidebook for Greenhouse Gas Reductions in Freight Transportation
Investigators: Billy Williams and H. Christopher Frey
Granting Agency: U.S. Department of Transportation via Center for Transportation and the Environment
Dates:
Brief Description: The study will investigate current efforts within the freight transportation sector to reduce emissions of greenhouse gases in order to develop a list of best practices and promising initiatives. The investigation will consider programs and demonstration projects developed at the state, local, or individual company/operator level. The investigation will also consider all modes of freight transport, including air, road, rail, and marine transport.
Title: Truck Anti-Idling Demonstration Project
Investigators: Anne Tazewell (NC Solar Center), H. Christopher Frey, and John Stone
Granting Agency:
Dates: February 2006 to February 2008
Brief Description: The objective is to assess potential environmental benefits of heavy duty diesel freight truck idle reduction technologies installed on trucks in NC. A key goal is to quantify actual grams per gallons emissions with a portable gas analyzer and compare this data with data extrapolated from an on-board data logger and fuel use with and without idle reduction technologies.
Title: Exposure Modeling Advice
Investigators: H. Christopher Frey
Granting Agency: National Exposure Research Laboratory,
Dates:
Brief Description: Dr. Frey will be on sabbatical to EPA/NERL as an Exposure Modeling Advisor. Key areas of work will include: (a) characterization of human exposures near-roadsides as a result of vehicle emissions; (b) methods for quantification of uncertainty in environmental modeling; and (c) methods for communication of uncertainty to senior-level decision-makers.
