The Wyoming DOE EPSCoR program supports building competitive applied
research capability through funding of research clusters in areas of science
and engineering of importance to both DOE and Wyoming. Specifically, the
Wyoming DOE EPSCoR program includes research in fossil energy, electrical
energy efficiency, and environmental science.
Human Resources Development: The
development of personnel who are educated and interested in energy-related
areas of math, science, and engineering is another objective of the Wyoming
DOE EPSCoR program. This year, the projects have involved 12 graduate students
and 12 Wyoming high school students. In addition, there have been 26 undergraduate
students working on the projects, including 22 from Wyoming, two from Colorado,
and one each from Minnesota and Montana.
The Earth System
Science Internet Project (ESSIP) links 5th — 12th grade students with
UW scientists and science educators. The activities focus on meaningful
"real world" problems, involve the students in hands-on data
collection and a web-based exchange of ideas and collected information
with students at other sites. Sixteen teachers from around Wyoming have
been involved in the development and revision of these initial activities.
In the summer of 1997, stipends were awarded to ten additional teachers
who will join the project in the fall. In the second phase of the project,
we will add a module which investigates coal mines and coal as an energy
source and we will provide workshops for all interested teachers in Wyoming
to join the ESSIP project.
Fossil Fuels Research Cluster: The
project to investigate upgrading coal without increasing the risk of spontaneous
combustion has completed theoretical studies associated with molecular
level interactions and the construction of the experimental batch reactor.
The results using CO2 for coal drying are encouraging. During the renewal
grant, a continuous feed fluidized bed reactor will be used and treated
coal will be tested for BTU content and stability.
The
project to formulate and produce cobalt phthalocyanines as catalysts for
removing nitrogen oxides from power plant glasses has produced some promising
species. Candidate catalysts will soon be tested in a scaled scrubbing
system.
The research on converting simple hydrocarbon
compounds (e.g. coal liquids) to important petrochemical products using
superacids has focused on the stability and reactivity of organometallic
catalyst systems under superacidic conditions. Following phases will address
the reactivities of carbonylation systems and the practical technological
applications of these materials.
A new coal upgrading subproject is being added
to this cluster which seeks to improve the manufacture of formed coke briquettes
from Wyoming coal. This project has been formulated in cooperation with
FMC Corp. and will investigate the role of oxygen in producing adequate
mechanical strength in the finished briquette. This research is a fine
example of a process that adds significantly to the value of a Wyoming
product, leading to economic development and job creation within the state
of Wyoming.
Electrical Energy Research Cluster: The
research on efficient and precise control of large electric motors has
resulted in theoretical algorithms that will improve the efficiency and
precision with which induction motors can be operated. A 7.5 hp inverter
that can implement the algorithms has been built and tested. A 60 hp version
of this inverter is under construction.
Upon the completion of economic payback testing of these control methods,
research will be moved to a demonstration phase with applications in both
oil well pumping and agricultural irrigation systems. In addition, a new
thrust aimed at the early detection and correction of motor drive power
system degredation will be pursued.
In the first grant period, important new measurement
and analysis capability was developed in the area of radio frequency interference,
both radiated and conducted. These facilities have been used to characterize
the electromagnetic compatibility (EMC) problems associated with a variety
of energy efficient devices. The next phase will result in the development
of statistical models of the interference. Such models will help to reliably
predict effects of radio frequency interference on other systems such as
cellular communications.
The large photovoltaic (PV) system is installed
and operating. The research in the next two years will examine the economics
of using PV arrays in the utility industry, including power quality issues,
increasing total power output by dynamic array reconfiguration, and the
use of demand-side management to increase the value of PV generation.
Environmental Science Research Cluster:
The environmental group has produced important
results in both remediation and pollution prevention projects. Progress
has been made in evaluating the utility of microbes in the remediation
of PCP contamination through dechlorination. Two genes have been amplified
from Flavobacterium and Pseudomonas species, which are now considered members
of a single genus, Spingomonas. These genes have been sequenced and subcloned
into E. coli overexpression vectors. Future work will focus on mutant isolation
and engineering strains capable of elevated rates of PCP metabolism.
In
a similar fashion, rhizosphere microbial communities from sites that are
contaminated with heavy metals (copper and uranium) have been collected,
examined, and characterized. The intent is to determine whether the efficiency
of phytoremediation of these sites can be improved through inoculation
of the plants with these microorganisms.
Surfactant enhanced electrokinetic (SEEK) remediation
for soils contaminated with petroleum products has produced some promising
results. In some lab studies, as much as 99% of the residual gasoline products
were removed. Various surfactant combinations in the more difficult case
of complex combinations of gasoline products in soil columns will soon
be tested.
Finally, three subprojects aimed at pollution
prevention are incorporated in the research work. One of these involves
new approaches to the reduction of emissions from drying of natural gas,
a process of great importance in Wyoming. Another is developing a commercially
viable method of spraying paints or coatings without the use of environmentally
dangerous solvents. The final project is being initiated in this study
period and involves new methods to dispose of explosives in a safe, environmentally
acceptable manner.
