Dr. Steve Lipka, CAER Associate Director for Electrochemical Power Sources, has been awarded a 2 year, $389,000 grant from The National Institute for Occupational Safety and Health (NIOSH). The title of the project is “Evaluating the Inherent Safety of Lithium-ion Batteries in Portable Electronics Used in Underground Mine Environments.”
This project will help to understand the safety of Li-ion battery chemistries used in portable electronic devices such as hand-held gas detectors, cap lamps, hand tools, communications devices, and tracking devices and their potential risk as an ignition source in an underground mine where there is a mixture of methane and air. In a catastrophic event, the battery can sustain mechanical damage, resulting in reactions between active battery materials and the highly volatile and flammable organic electrolyte. These reactions can result in rising cell temperatures which accelerate further chemical reactions in the battery causing heat and gas generation. The project will evaluate the ignition potential of various Li-ion battery chemistries in both cylindrical and prismatic cell formats in a simulated underground mine environment under mechanical damage.
Lipka’s group will recommend safer lithium-ion battery chemistries and use in portable devices. The researchers will also develop strategies to stop or reduce potential ignition for lithium-ion batteries used in underground mines.
Professor Thomas Novak of UK’s Department of Mining Engineering will serve as a project consultant.

A demonstration scale photobioreactor (PBR) is being operated and expanded at Duke Energy’s East Bend Station located in Union, KY. The PBR converts the CO2 in flue gas to algal biomass, via photosynthesis.
The biomass is then periodically harvested to supply feedstock for upgrading into value added products. The low energy harvesting system recycles water and unused nutrients. Partners include: KY Department of Energy Development and Independence; US-China Clean Energy Research Center-Advanced Coal Technology Consortia; ENN Group; and Pittsburgh State University.

To promote young women in science, CAER staff spent a day mentoring two female high school students. Simone Stigall (front left) and Alex Raines (front right) job shadowed Liz Ware (back left) and Anne Oberlink recently. They learned about biofuels and low energy cement. Several of the lab's female researchers and college students joined them for lunch and discussions regarding careers in science.
Congratulations to Teresa Epperson (left front), Theresa Wiley (right front), Jim Hower (left second row), and Wayne Pettit for receiving 30 and 35 year service awards from UK.
When the UK Center for Applied Energy Research’s renewable energy laboratory building opened a year ago, it was with energy conservation in mind. A year’s worth of data shows a total energy reduction of 55% compared to a typical laboratory building its size. This is not estimated, but an actual savings based on the utility bills. This took a team commitment from design to operations. Much of the conservation took place after the completion of the building by operating and maintaining the building to achieve these savings.
To illustrate this cost savings magnitude, last year the utility costs of the original CAER building (erected in 1977) was $258,694 ($4.88 per square foot). The new building’s utility cost was $111,181 ($2.58 per square foot). This is a difference of $147,000 per year in utility savings that can be directed towards research rather than building consumption.
Part of the energy reduction is accomplished by energy-saving features throughout the building, including an exterior and roof with twice the amount of insulation normally used. Office windows receive southern-directional light and contain a nanogel material that diffuses sunlight and provides the same insulation as brick walls. Among other features are geothermal heating and cooling, occupancy sensors that turn off lights automatically when no one is there, and a ventilation system that recaptures energy.
The original engineers (CMTA Engineering Consultants) are now studying trends in the building and believe that there are opportunities to reduce energy consumption even further.
At the recent 23rd North American Catalysis Society conference, Burt Davis received a joint award from the group and the Tri-State Catalysis Society (TSCS) for his Fifty Years of Dedicated Service to the Catalysis Society and his Documenting and Archiving the History of Catalysis. As the current president of TSCS, CAER's Uschi Graham had the pleasure of presenting the award.
Kunlei Liu (CAER Associate Director) presented John Moffett (LG&E Manager Research & Development) a CAER Distinguished Service Award upon his upcoming retirement from LG&E. John was instrumental in the formation of the CMRG (Carbon Management Research Group), a consortium of Kentucky's major power companies and CAER. The group is carrying out a $24M ten-year program of research to development and is demonstrating cost-effective and practical technologies for reducing and managing CO2 in existing coal-fired electric power plants.
Electrochemistry expert Steve Lipka is one of the early grantees in the recently announced UK-GE master agreement to collaborate on research projects. This partnership could yield research towards inventing future appliances.
The record-breaking 23rd Meeting of the North American Catalysis Society got off on a fast track at an opening reception at Churchill Downs this month. A large portion of the successful conference was organized by University of Kentucky Center for Applied Energy catalysis scientists.
This biennial meeting, with its large international participation, is the premier scientific event in the field of catalysis. The Tri-State Catalysis Society hosted the 23rd North American Meeting (NAM) in Louisville and this event surpassed all previous NAMs with 1,300 attendees, 54 exhibitors, 400 oral presentations, 600 posters, $278K in general sponsorship from 38 sponsors, and $75K in Kokes awards to enable students to participate in the meeting.
CAER researcher Uschi Graham was the co-meeting chair, along with Umit Ozkan (The Ohio State) and Madan Bhasin (MATRIC). CAER Associate Director Burt Davis was the honorary chair; and CAER researcher Gary Jacobs chaired the Kokes Student Award Committee.
CAER researchers Anne Oberlink and Liz Harman-Ware reached out to high school girls at the EKU Girls’ STEM Day recently. The scientists were accompanied by two high girls who recently toured CAER. STEM practitioners and educators led girls through activities that mirror real-world STEM tasks and highlight creative and innovative problem solving. Anne and Liz exhibited and served as mentors.

The Cooperative Research Network and the Centre for Energy Advancement through Technological Innovation research organizations held task force meetings at CAER. Both of these organizations are created to perform research and solve problems for the electric utility industry. The CRN’s members are the Rural Electric Cooperatives and the task force that met at CAER is the Generation, Fuels and Environment Group. CEATI is a similar group made up of international utilities. A portion of their time was also spent in presentations on CAER research and an in depth tour.
Elementary, middle school, and high school students from around the area monitored building efficiency, saw how fresh flowers can freeze quickly via liquid nitrogen, and discovered that algae is not just pond scum during tours of CAER this spring.
The students hailed from Russell Cave Elementary, which celebrates its decade long partnership with CAER this year; Clark County Middle School through its partnership with Bluegrass PRIDE; and a group of female high school students from Fayette County’s “Green Team.”
There were around 150 students in total. While the tours were more detailed to suit the groups’ grade level, all seemed fascinated by the science. The students were impressed when told that the newest building on CAER’s research campus uses around 60 percent of the energy for a regular building its size. They were equally as enthralled with the idea that algae could be used to capture carbon dioxide emissions from power plants.
In addition to the demonstrations, researchers discussed their backgrounds, education, careers, and the need for future energy experts.
