The University of Kentucky Center for Applied Energy Research has hosted two recent tours - a group from the Kentucky Geological Survey and a group from the Kentucky Association of Manufacturers organization. Both groups had to dodge a few raindrops but came away from the tour with more insight into the scientific energy research conducted at CAER.

Some of the stops included:

  • Algae Greenhouse (CO2 capture with algae) and Biofuels (fuels, chemicals and other products created from harvested algae)
  • Minerals Processing (utilization of coal ash by-products used to produce UKCAER/Minova's Tekecrete products, use in concrete and other building materials)
  • Carbon Materials processing (creation of carbon fibers used in the automotive and airline industries)
  • Electrochemical Power Sources (creation and/or testing of batteries used in autos, retail products, etc.)
  • Coal/Biomass-to-Liquids Pilot Facility (gasification of CBTL to synthetic fuels)
  • Solar/Organic Materials (creation of new, advanced thin-film technologies from organic compounds).

Tekcrete Fast, the rapid-strength, high-bonding shotcrete material created by UK Center for Applied Energy Research and its corporate partner Minova USA, Inc., is the first UK CAER-created product to receive a Russian patent.

Tekcrete was created by UK CAER and Minova as a high-end, low-energy concrete alternative. It has been primarily used for infrastructure repair and stabilization but is drawing interest from many other markets. The Russian patent is the third for Tekcrete, which already holds patents in the United States and Australia.

Exploding balloons. A solar car. A virtual reality sandbox. Sounds like a day at the museum, doesn’t it?

The reality: It was the annual University of Kentucky Center for Applied Energy Research (UK CAER) Energy Fair on Monday, April 11. Sayre School hosted the event at its C.V. Whitney Gymnasium, which featured more than 330 students from Cassidy, Russell Cave, Sayre and Yates Elementary Schools participating.

Held each year, the UK CAER Energy Fair provides elementary school students in Fayette County a hands-on, interactive introduction to science, engineering and research. Students learn about various energy-related topics including electricity, mining, biofuels, motors, solar panels, and electromagnets. In addition, students had the opportunity to learn about creating a sustainable energy future for the Commonwealth.

In addition to CAER, presenters included the UK Chapter of the Society of Mining Engineers, Bluegrass GreenSource, UK’s Solar Decathlon team, Sayre Middle School Green Team, and the Kentucky Division of Air Quality, among others.



UK CAER's Tekecrete Featured at First Defense Expo

clock April 1, 2016 12:55 by author Alice

A new technology developed at the University of Kentucky Center for Applied Energy Research and Minova's North American headquarters in Georgetown, Kentucky was exhibited at the FDX 2016 First Defense Expo in Louisville in mid-March 2016. CAER and Minova scientists reached out to the first responder community by discussing Tekcrete Fast. This product/process allows a fiber-reinforced, high-strength, ultra-rapid setting concrete to be applied for almost immediate stabilization of damaged buildings and other damaged concrete infrastructure. The process can be sent into the location immediately and be used at a safe distance.

The Tekcrete Fast technology used the construction technique called shotcrete and is applied at high velocity that also facilitates adherence to various construction surfaces. A slightly different formulation, Tekcrete Fast M, is used in underground applications to almost instantly stabilize dangerous mining conditions, contributing to mine safety.

The research and joint patent leading to the Minova license came about when UK CAER partnered with Minova on a project for the National Institute of Hometown Security (NIHS), located in Somerset, Kentucky.

Center Collaborates with UK Mining Engineering on Rare Earth Elements Research

clock March 15, 2016 08:56 by author David Melanson

University of Kentucky Center for Applied Energy Research scientists Jack Groppo and Jim Hower are collaborating with Rick Honaker, professor and chair of the UK Department of Mining Engineering, to develop a mobile pilot-plant facility for the recovery of rare earth elements from coal.

The research team received $1 million from the U.S. Department of Energy (DOE) National Energy Technology Laboratory. The team includes collaborators at Virginia Tech and West Virginia University and will develop and test a mobile processing facility that can efficiently recover the rare earth elements present in coal and coal byproducts in an environmentally friendly manner.

"Previous research conducted by UK scientists and others have found that the critical materials needed for renewable energy technologies, such as cell phones and other electronics, are found in coal and coal byproducts at concentrations that may be economical to recover," Dr. Honaker said.

Rare earth elements, or REEs, are a series of chemical elements found in the Earth’s crust. Due to their unique chemical properties, REEs have become essential components of many technologies spanning a range of applications including electronics, computer and communication systems, transportation, health care and national defense. The demand, cost and availability of REEs has grown significantly over recent years stimulating an emphasis on economically feasible approaches for REE recovery.

The U.S. has 10.9 million tons of rare earth resources in coal deposits located in just five western and four eastern states, including Kentucky, West Virginia and Virginia, according to the U.S. Geological Survey Coal Quality Database.

"If advanced separation technologies become available, the resource base will increase substantially," Dr. Honaker said.

With those technologies, the coal industry could potentially produce approximately 40,000 tons of REEs annually, which is more than twice the amount consumed in the U.S.

As Chairman of the House Appropriations Committee, U.S. Rep. Hal Rogers (KY-05) supported funding for REE recovery projects in the federal budget for fiscal year 2016.

“Our coal-producing states are working diligently to recover from the devastating loss of coal mining jobs in today’s economy. In fact, Kentucky alone has suffered the loss of nearly 11,000 coal mining jobs since 2009. Experimental projects, like UK’s mobile REE recovery plant, could save and create new coal-related jobs and opportunities in eastern Kentucky,” said Congressman Rogers. “I applaud Professor Honaker and the vision of UK’s leaders to find new applications for coal and coal byproducts for the development of everyday technologies, such as smart phones, computers and rechargeable batteries. This effort to find more uses for our country’s most plentiful resource could put many people back to work in the coalfields.”

This project is one of only 10 projects awarded and is the only one that is focused on physical concentration methods as a means for recovering REE directly from the coal sources rather than from a coal combustion byproduct. UK CAER received funding on three of 10 NETL projects.

ABSTRACT: Twenty bulk samples were collected from ponded coal combustion ash in Shanxi Province, China, as part of an investigation of their beneficiation potential. The samples were shipped to the University of Kentucky, where they were chemically analyzed. The samples were highly consistent in chemistry, falling within the ASTM C-618 class F compositional range. The particle size of the ponded ash was relatively coarse, with only, 7% by weight on average, falling below 200 mesh (75mm) particle size. The bulk of the material (80%) was within 50 by 200 mesh (equivalent to 300 by 75mm). X-ray diffraction investigation combined with microscopy indicated that the agglomeration was probably due to the presence of small amounts (i.e.,,3.5%) of gypsum. The utilization potential of the ash was assessed in light of its characteristics and location. The presence of sulfate and relatively high alumina concentration, which averaged, 37%, suggested that it may serve as an important ingredient in the fabrication of a Portland–calcium sulfoaluminate (CSA) hybrid cement. Portland-CSA hybrid clinkers were successfully produced from this ponded ash when mixed with hydrated lime, gypsum, fluorite, and bauxite. The raw mixture was fired at 1250u C for 60 minutes twice (sample D) and consisted of approximately 40% alite (C3S), 21% belite (C2S), 3% ferrite (brownmillerite or C4AF), 32% CSA (ye’elimite, Klein’s compound, or C4A3SO3), and no free lime by weight.

Seed Projects Starting to Blossom

clock January 13, 2016 11:49 by author David Melanson

The success of the University of Kentucky Center for Applied Energy Research’s seed grant program was on full display Wednesday, as UK CAER investigators presented early-stage research projects to fellow CAER colleagues.

CAER’s seed grant program was created to bridge the divide between internal creative ideas and large government grants and/or industrial funding, with the objective being to develop a process of converting new research concepts into competitive proposals.

The success of the program can best be illustrated by the results. Since January 2013, CAER has invested $430,000 into seed projects. Those same projects have generated more than $940,000 in external funding and seven published papers. In fact, of the five external proposals submitted on behalf of seed projects, all five have received funding.

“The results are pretty obvious,” said Andrews. “We knew that CAER investigators had some novel concepts that simply needed some start-up funding to get off the ground, and this program allowed us to fund those innovative, early-stage ideas. It is exciting to see these concepts grow and receive support from external agencies, as they move into the next phase of discovery.”

On Wednesday, the following projects were spotlighted during the seed grant poster presentations event at CAER. These projects were all funded in 2015.

 

  • Michael Wilson, Stephanie Kesner, and Daniel Mohler - Integrating Algal Based CO2 Utilization and Waste Water Treatment

Photosynthetically grown microalgae have the potential to recycle many waste streams, including CO2 emissions and municipal, agricultural, or industrial waste water.  Samples were obtained from the Lexington Fayette Urban County Government Division of Water Quality to evaluate the suitability of waste water as a nutrient source and habitat to culture microalgae.  Ion chromatography was used to evaluate various waste water streams from the Town Branch wastewater treatment plant and to track nutrient uptake of algae cultures. Although the waste streams sampled did not contain high values of usable nutrients, it’s suitability as an industrial scale habitat was verified.

 

  • Tristana Duvallet and Anne Oberlink - Sulfate-Activated Class C Fly Ash Based Cements

Recent research in the Environmental and Coal Technologies (ECT) group has determined that Wyodak coal source Class C fly ash can be activated through a sulfation mechanism with anhydrite to produce the fly ash equivalent of a “super-sulfated cement.” This constitutes a discovery that is of significance. Concretes and mortars produced with high levels of coal combustion products (CCPs) or supplemental cementitious materials (SCMs), such as fly ash or slag, in place of Portland cement can develop strength by the activation of the alumina and silica phases of the materials using strong alkalis (i.e. alkali activation, aka “geopolymer”). The alkali that is used as the activator is typically sodium or potassium silicate in combination with sodium or potassium hydroxide, and various alkalis, e.g. borates, citrates, sulfonates, etc. Drawbacks to this approach include: erratic setting, either lack of, or very slow setting or flash setting; slow strength development that may require curing at elevated temperatures; rheological problems with the concrete or mortars themselves, i.e. they become “sticky”; worker safety issues since high levels of sodium hydroxide exposure are dangerous; and long-term issues with surface efflorescence. Sulfation activation was thought to be a phenomenon restricted to ground granulated blast furnace slag (GGBFS) cement. The observation that a supersulfated cement can be based entirely on Class C fly ash instead of GGBFS, overcoming the drawbacks of alkali activation, has the potential to lead to a new generation of low energy, low CO2 concretes and mortars.

  • Robert C. Pace - Biomass Fractionation via a Semi-continuous Method: Lignin Extraction with Ionic Liquids

Ionic Liquids (ILs) are highly adaptable organic salts which are liquid at room temperature. As a consequence of these properties, ILs are enormously effective in the dissolution of lignocellulosic biomass.  Given the tremendous interest in the production of renewable fuels and chemicals from lignocellulose, these solvents present a novel pathway toward the fractionation of lignocellulose into its three primary components; cellulose, hemicellulose and lignin. Fractionation of these compounds is necessary for the use of the whole of the biomass, a requirement for cost-effective production from these feedstocks. To date, nearly all biomass fractionation using ILs has been conducted in batch processes. Since continuous extraction systems are often more energy efficient and economical, this project will set out to construct a semi-continuous extraction system which is capable of overcoming the high viscosities of ILs. In order to discern the effects of various functionalities as well as the impact of cation/anion effects, five ILs will be examined as extraction solvents. The products of these fractionation experiments will also be analyzed by various means, including thermogravimetric analysis, pyrolysis-GCMS and gel permeation chromatography.  This work will lead not only to valuable data which can be utilized in publications and future grant proposals, but will also generate an apparatus which is capable of producing unique IL extracted biomaterials which could be sold as commodity products and utilized by students in their own research projects within the BEC group.

  • Chad Risko, Adam Rigby and Karl Thorley, - A Computational, Shape-Based Approach to Crystal Engineering

Organic semiconductors (OSC) are experiencing rapid application growth in consumer electronics, with OSC poised to serve a key role in next generation flexible, conformable, and wearable electronics. However, the reliance on largely Edisonian discovery processes results in significant development and production costs – in terms of personnel, materials, characterization equipment, and time – for new, molecular-based OSCs. High-performance computing, when combined with the tool set and know-how of the synthetic chemist, offers a means to overcome many of these costs. Through a joint collaboration between the Anthony and Risko groups, we are developing an innovative computational approach to determine how the interplay between of molecular shape and explicit chemical functionality drive molecular packing in the solid state, a key determinant of OSC performance. The development of the computational platform will allow for rapid approximations of molecular packing structures, with relevant solutions arriving within days and weeks rather than the months required for synthesis and characterization, along with the ability to screen varied and unusual molecular designs that may otherwise go untried. Through the course of the work, the research team has improved understanding as to how solid-state molecular conformations impact the intermolecular electronic coupling, a key parameter directing charge-carrier transport in these materials. The project introduced a new concept, the disordermer, into the crystal engineering lexicon, and shown how changes in chemical composition can be manifest on crystalline order and the resulting charge-carrier transport properties. The lab has also made considerable headway in terms of developing a model that reveals how adjustments in the overall molecular shape and volume direct solid-state packing. The work has resulted in three peer-reviewed publications (two published and one submitted) and one proposal submitted to the National Science Foundation.

  • Rafael Franca and John Craddock - A New Approach to Novel Zeolite Hollow Fiber Membranes for Dewatering and Enrichment Separations in CO2 Capture Process

Zeolite membrane-based technology for dewatering of aqueous amine-based CO2 sorbents, has the capability to significantly decrease the energy required for CO2 capture from coal-fired power plants. Membrane enabled dewatering of CO2 saturated amine solvent, reduces the thermal energy required by the stripper during solvent regeneration by commensurately reducing the volume of water to be heated. The hollow fiber membrane (HFM) geometry provides high surface area to volume and high permselectivity. These membranes have the potential to increase selectivity and flux in membrane-based dewatering processes when compared to conventional tubular membranes. In this work, we introduced the preparation of a novel, polymer-assisted processing of a Y Zeolite HFM support. The preparation method proposed is based on air-gap solution spinning of a polymer (polyethersulfone (PES)) solution containing highly dispersed mullite particles, followed by thermal treatment to pyrolize the polymer and sinter the mullite particles into an HFM form. It is expected that this new design (HFM) would greatly increase flux and selectivity of Y zeolite membranes for the dewatering of carbon-loaded amine solvents. Preliminary results indicated that mullite based hollow fiber supports did not present enough mechanical resistance after the sintering process. Zeolite Y crystals have been successfully grown on the outside surface of PES hollow fiber supports, however some level of degradation was observed when the support was exposed to the carbon loaded amine solvent. It is not clear if the degradation process affects the porosity of the PES hollow fiber support. Further tests will be conducted with PES hollow fibers to analyze the viability of using PES as a support for Y-zeolite hollow fibers.

  • Christopher Swartz, "Hybrid Redox Flow Battery for Stationary Energy Storage Applications

The capability to store electricity is on track to become an integral component of the future electrical grid. Emerging technologies found in the grid storage portfolio include pumped hydro energy storage, compressed air energy storage, thermal and flywheel energy storage, and various electrochemical energy storage options, including redox flow batteries. Redox flow batteries share many similarities with fuel cells, and are rechargeable, modular battery systems where energy storage and power performance can be decoupled from one another due to the battery architecture. The all-vanadium redox flow battery represents the current state-of-the-art in flow battery technology, and numerous demonstration units have been installed worldwide, ranging from kW, kWh to MW, MWh capabilities. The relatively high cost of these systems has prevented widespread adoption of flow battery technology, and new flow battery systems featuring lower cost chemistries and ion exchange membranes (when compared to vanadium and Nafion®, respectively) remain highly attractive candidates to move flow batteries along on a forward trajectory to the commercial marketplace. The Electrochemical Power Sources Group proposes to develop a low-cost hybrid redox flow battery as an alternative to the all-vanadium system, based on aqueous iron and zinc electrochemistry. The cathode will feature plating and stripping of Zn metal during cell charge and discharge. The anode will feature the Fe2+/Fe3+ redox couple, with the addition of various ligands or chelating agents which will bind to iron, and lead to higher operating cell voltage and energy density.

Podcast of CAER Seminar Speaker - Professor Bittnar

The University of Kentucky's Center for Applied Energy Research has published another podcast for individuals interested in energy issues.

It explored the topic of Validation of Multiscale Model for Heat Generation in Hardening Concreteby Professor Bittnar, Civil Engineering, Fellow of the Engineering Academy - Czech Technical University.

- Podcast and PPT File

Temperature rise in hydrating concrete presents a formidable problem that may lead to significant acceleration of hydration kinetics, early-age cracking, and decreased durability. Multiscale formulation was developed, coupling a cement hydration model on the microscale with the finite element method (FEM) solving heat conduction problem on the macroscale. Although discrete hydration model predicts heat evolution controlled by macroscale temperature, the FEM satisfies heat balance equation during thermal conduction. 2D validations show reasonable temperature agreement with an access to the local quantities, such as a degree of hydration. Here, this multiscale and coupled model is validated against two in situ bridge constructions.

The rarest of them all --Could coal ash save your smartphone? Researchers try to find out ...

 

That is the title of the article published in PowerSource which interviewed Dr. James Hower, Petrologist and Scientist at the University of Kentucky Center for Applied Energy Research.  The following is excerpts taken from the article:

The crux of the matter is that iPhones draw their properties from rare earth elements, a 15-chunk block of lanthanides at the base of the periodic table, plus the metals scandium and yttrium. By 2010, China had cornered nearly 95 percent of the world’s production of rare earths and had begun to choke exports, which caused prices to skyrocket.

Back in his lab at the University of Kentucky, Jim Hower, a geologist, started to see a wave of interest in his research like never before. Mr. Hower has been sampling slabs of Appalachian coal and its waste products and cataloging their rare earth element concentrations for years. Dr. Hower and researchers at the U.S. Geological Survey have done a lot of the cataloging of coal characteristics across the country. Now there seems to be an increased interest in rare earths from the U.S. Department of Energy.
