UK CAER, IU Bloomington Launch Sustainable Collaboration

clock October 4, 2018 14:17 by author Thomas

 

Indiana University Bloomington and the University of Kentucky may be rivals on the hardwood but when it comes to sustainability, these two schools are clearly on the same page.  

A $50,000 grant from Duke Energy will help make IU Bloomington one of the first universities in the U.S. to convert emissions from its heating plant into fertilizer to feed campus vegetation.

The technology utilized to make this happen was invented and patented at UK’s Center for Applied Energy Research.

Working with UK CAER engineers, IU Bloomington has installed a ‘cyclic flow’ photobioreactor system on the roof of its Central Heating Plant. The system will convert carbon emissions from the natural gas boiler into fertilizer via photosynthesis, enhancing sustainability efforts already underway across the campus.

UK CAER originally designed its photobioreactor system to capture and beneficially re-use carbon dioxide emissions at coal-fired power plants. The photobioreactor creates an optimum growth environment for microalgae, which naturally scrubs the CO2 as it grows. Periodically the algae are harvested and can then be used as biomass to create a variety of products, including food, fertilizers, chemicals, and/or plastics.

The Center’s first algal photobioreactor was installed at Duke Energy’s East Bend Station in northern Kentucky. 

At IU, emissions generated from the heating plant's natural gas boilers will be pumped into the bioreactor tubes, which house the algae culture. The transparent tubes allow sunlight to drive photosynthesis, converting the CO2 emissions into algae biomass. After harvesting, the algae can be processed to create a sustainable, nutrient-rich, slow release fertilizer. This fertilizer will be utilized in flower beds and landscaping across campus.

Mark Menefee, Assistant Director for Utilities at IU, credits the diversity and dedication of the IU team that has worked on the project. He noted that the project brought together professors, students, facility engineers and electricians, administrative staff, and collaboration with UK CAER and Duke Energy to complete this project.

“Success depended on all these collaborators being able to effectively communicate with each other. Many bridges between disciplines needed to be crossed. It was clear, even early on that our shared passion to see this project succeed united us,” Menefee said.

This is the not the first system that UK CAER has partnered to build. In recent years the Center’s biofuels team has partnered with Lianhenghui Investment Company to construct a 5-acre algae production facility in Zhengzhou, China.

Although the system is similar to those UK CAER has built in the past, the Center’s Michael Wilson is excited about IU’s efforts in utilizing algae to create a sustainable fertilizer.

“I look forward to learning from the results in Indiana,” said Wilson, a Senior Research Engineer at UK CAER. “Many colleges, universities, and companies have power plants at their facilities. They also utilize fertilizers as part of[WM1]  their landscaping and beautification programs. If successful, this may provide a new avenue to create those products from a sustainable source, while reducing their carbon footprint.”

Wilson credits the vision of IU’s Stephen ‘Chip’ Glaholt for utilizing the project as a way to stimulate applied, multidisciplinary, undergraduate research across campus – essentially as a living laboratory.

“It is a very exciting concept,” said Wilson. “It creates a win-win-win, highlighting sustainability efforts, engaging students, and advancing applied carbon utilization research.”

clock October 1, 2018 14:09 by author Thomas


Burtron H. “Burt” Davis, a University of Kentucky Center for Applied Energy Research investigator and one of the most revered Fischer-Tropsch synthesis researchers in the world, passed away Friday, September 28 in Lexington, Kentucky. Service details can be found here: http://www.johnsonsfuneralhome.com/book-of-memories/3619109/Davis-Burtron/obituary.php

Born in Points, West Virginia, Dr. Davis graduated with a bachelor’s degree in chemistry from West Virginia University in 1959 before earning a master’s degree from St. Joseph’s College in Philadelphia. Davis received a PhD from the University of Florida in 1965, followed by a postdoctoral position under Paul Emmett at Johns Hopkins from 1965-66. He then accepted a position for Mobil R&D Corporation, where he conducted research on naphtha reforming and aromatics hydrogenation. In 1970, he received his first academic appointment as Associate Professor of Chemistry at Potomac State College in West Virginia.

Dr. Davis was recruited to UK CAER in 1982, helping to establish the Center as one of the foremost energy research and development institutes in the nation. He has led the Center’s Clean Fuels and Chemical (CFC) group since its inception, and established the University as global experts in catalysis, FT, and direct coal liquefaction. He also served as Interim Director for UK CAER and was an adjunct faculty member in UK’s Department of Chemistry.

Dr. Davis created a unique program at UK CAER that involved both academic and industry-supported work. He developed a laboratory with extensive capability in the use of tracer isotopes in reaction mechanism studies and materials characterization, and developed research programs in: Fischer-Tropsch Synthesis, surface science studies, heterogeneous catalysis, materials science, organic analysis, 1/4 ton per day direct coal liquefaction pilot plant operation, liquefaction mechanistic studies, clean gasoline reforming with superacid catalysts, and upgrading naphthas.



“The Center would not be the place it is today without the contributions of Burt Davis,” said Rodney Andrews, UK CAER Director. “Developing a research program that maintained academic independence while simultaneously working on solutions to industry problems was new to higher education. Burt was not simply able to work in both these worlds, he was well-respected by all those he collaborated with for his expertise, professionalism and trademark sense of humor. He left an indelible mark on all of us at the Center, and he will be sorely missed.”

He held numerous offices and memberships in several professional societies, including the American Chemical Society (ACS), the Catalysis Society, and Materials Research Society. He has authored/coauthored over 850 publications and has received four Elsevier most-cited author awards. He served as a member of the Sasol Heterogeneous Catalysis Advisory Board for ten years.  

Dr. Davis was awarded the prestigious Henry H. Storch Award in Fuel Science in 2002 by ACS for his significant contributions in catalysis, Fischer−Tropsch synthesis, and coal conversion research.  In 2011, Dr. Davis became an ACS Fellow. In 2014, was presented the “Distinguished West Virginian Award” by then-Governor Earl Ray Tomblin. In July of this year, Dr. Davis received a citation of appreciation from the Kentucky House of Representatives, nothing his “invaluable knowledge and expertise in the interest of the greater good” of the Commonwealth of Kentucky.

UK CAER Researchers Spinning a Path Forward for Kentucky Manufacturers

clock June 6, 2018 10:25 by author Thomas

For years, Kentucky has been known as a national manufacturing hotbed for a variety of reasons. Home to inexpensive, reliable energy and a global leader in aluminum production has kept Kentucky communities churning out products — and keeping Kentuckians gainfully employed — for generations.

 

But it is a different material that shows great promise in the Commonwealth.

 

Carbon fiber is the material of the future — a next-generation version of aluminum. Its properties are often considered the holy grail in manufacturing. Carbon fiber is a low-weight, high-strength, corrosion resistant material that can conduct electricity.

 

 

Industry leaders agree that if you intend to be at the leading edge of advanced manufacturing, you better understand carbon fiber’s importance, and you better be actively adapting to a rapidly changing marketplace.

 

The good news for Kentucky manufacturers is that one of the leading carbon fiber research and development facilities in the world is located in their backyard.

 

The University of Kentucky Center for Applied Energy Research (CAER) is home to the largest carbon fiber spin line at any institution in North America. Over the past decade, CAER researchers have built a solution spinning line that draws visitors, collaborators, and research partners from across the Commonwealth, the nation and the world. And they are here for one thing: to lean on CAER’s carbon fiber research team as they seek answers to some of the toughest questions facing the industry.

 

There are already numerous products in the retail and commercial marketplace that are made from carbon fiber composites. Sports equipment, aircraft and aerospace applications, satellites, automobiles, pressure vessels, specialized tools and wind turbine components, just to name a few.

 

According to Matt Weisenberger, associate director for CAER’s Materials Technologies Research Group, there is one thing keeping carbon fiber from truly taking off in the materials marketplace: cost. It is extremely expensive to produce carbon fiber. Much of that cost is tied to the production of precursor fiber — the first material created as part of the spinning process.

 

That’s what makes CAER’s expertise in this field so vital. CAER has spent a decade specifically developing technology related to the production of precursor fiber.

 

 

 

“Our team has developed the unique know-how to manufacture at a small scale — but a meaningful scale — experimental polymers and precursor carbon fibers,” Weisenberger said.

 

With Kentucky’s focus on becoming a national leader in advanced manufacturing, Weisenberger notes that UK CAER is primed to help partner with Kentucky companies to ensure the Commonwealth remains at the leading technological edge.

 

“As Kentucky’s land-grant university, we understand the important role we play in collaborating with Kentucky companies,” Weisenberger said. “We take great pride in working with industry and we look forward to more opportunities to do that with manufacturers in the Commonwealth, across the nation and throughout the world.”



UK CAER Grant Seeks to Reduce Carbon Capture Costs

clock May 22, 2018 14:25 by author Thomas

 

The University of Kentucky Center for Applied Energy Research (UK CAER) received a $3.7 million United States Department of Energy (DOE) grant to develop an intensified process to significantly reduce the capital and operational costs associated with CO2 capture.

This project, funded through DOE's National Energy Technology Laboratory, is entitled, "A Process with Decoupling Absorber Kinetics and Solvent Regeneration through Membrane Dewatering and In-Column Heat Transfer." James Landon, a Principal Research Engineer at UK CAER, and Kunlei Liu, Associate Director for Research, are co-principal investigators on this grant.

 

The project will investigate the intensification of amine-based CO2 capture from coal-fired power plants to reduce the capital and operational cost associated with CO2 capture through the use of innovative packing materials to enhance CO2 absorption into the solvent, dewatering of rich solution prior to stripper to reduce solvent regeneration energy, and heat integration to lower the steam requirements of the process. This technology will be demonstrated at the bench-scale at UK CAER through modification to the Center's coal-fired 0.1 MWth post-combustion carbon capture unit.

"The successful development of the proposed technology will allow for the utilization of abundant, low-cost coal to produce reliable electricity, while affordably meeting and managing environmental concerns," said Dr. Liu..

Enabling low-energy and low-cost carbon dioxide capture units is critical in the development of advanced coal-based power generation facilities. The research investigated through this project as well as the collaborations and integration of process components will help improve carbon capture technology available to utility companies. This process could be applied to most advanced solvents (aqueous or non-aqueous) and flue gas derived from either coal or natural gas combustion.

"If successful, this project could significantly change how we capture carbon," said Dr. Landon. "Creating an integrated process that captures CO2 while utilizing less energy in that process is critical to ensuring commercial scale carbon capture technology becomes a reality. This research is the next step in that technological continuum."

Project collaborators include the Lawrence Livermore National Laboratory, Media and Process Technology, Smith Management Group, and Trimeric.

Federal Funding to Expand UK CAER Carbon Capture Research

clock May 2, 2018 11:39 by author Thomas

The University of Kentucky Center for Applied Energy Research was one of nine organizations selected to receive Phase I funding of a three-phase project as part of the U.S. Department of Energy’s (DOE) Fossil Fuel Large-Scale Pilot program.

UK CAER will receive over $940,000 from DOE’s Office of Fossil Energy and the National Energy Technology Laboratory (NETL) to advance its world-renowned carbon dioxide capture research and development.

According to principal investigator Kunlei Liu, this Phase I funding will allow UK CAER to advance its four-pronged CO2 capture system to a 10 megawatt scale. UK CAER’s Power Generation Research Group is a global leader in building, developing and demonstrating post-combustion carbon capture systems. In fact, UK CAER’s current 0.7 megawatt small pilot CO2 capture facility operates at Kentucky Utilities’ E.W. Brown Generating Station in Burgin, Kentucky has led to scientific and engineering breakthroughs in the field.



This new federal funding will allow UK CAER to advance that research by nearly ten times, leaving the technology only one step away from commercialization. 

“This project will allow us to leverage the unique carbon dioxide capture expertise we have developed at UK CAER over the past decade to tackle a new and exciting next step in its implementation,” said Heather Nikolic, a Principal Research Engineer at UK CAER.

The Center’s post-combustion system features modular equipment and free-standing columns with built-in advanced controls to continually minimize the CO2 capture energy penalty while responding to a dynamic external demand. The new system will combine several facets to simultaneously address capital cost, energy consumption, load change, and environmental impact.

“I often remind our team that this project would not be possible without the many partners who have assisted us and collaborated with our researchers over the years,” said Dr. Liu, Associate Director for Research at UK CAER and Associate Professor in UK’s Department of Mechanical Engineering. “This project is another great example of that. In addition to our colleagues at DOE, we will be partnering with several institutions and industry partners to ensure success.”

Project collaborators include LG&E and Kentucky Utilities, Carbon Clean Solutions, University of Texas-Austin, Membrane Technology Research, Electric Power Research Institute, Huaneng Clean Energy Research Institute, Koch Modular Process Systems, Worley Parsons, and Smith Management Group.

“UK CAER has made many contributions to the scientific and engineering community, including through efforts to advance clean coal and carbon capture technologies, which are very important to Kentucky,' said Senator McConnell. 'The University of Kentucky, under the leadership of President Eli Capilouto, continues to do impressive work on this issue, and I've been told its current carbon capture project is already producing results. I look forward to seeing what UK CAER is able to accomplish with these new federal resources.”

Allegheny Front, a Pennsylvania-based public radio station, recently reported on the efforts to explore rare earth element extraction and research in the Appalachian region. It focused on, among others, the work of Dr. James Hower from the University of Kentucky's Center for Applied Energy Research. From the article:

Hower says that in order for a rare earths industry to be successful in the region the industry will need to be headquartered in the region that produces the material.

“You don’t want to transport this material too terribly far,” Hower explained, “because you have a lot of material that is not rare earths that you have to then put back somewhere. Ideally we want to be working at source landfills, do initial processing there, and then send more finished products somewhere else for further polishing.”

New UK CAER Grant Seeks to Improve Industrial Water Treatment Technology

clock February 19, 2018 12:11 by author Thomas

The University of Kentucky Center for Applied Energy Research (UK CAER) received a $740,000 grant from the United States Department of Energy’s National Energy Technology Laboratory (DOE NETL) that seeks to lower the cost for and improve the efficiency of industrial water treatment.

 

The grant – entitled “Intensified Flue Gas Desulfurization Water Treatment for Reuse, Solidification, and Discharge” – will help advance UK CAER’s impressive portfolio of water treatment research, a critically important project for Kentucky companies.

 

“This grant will strengthen our wastewater research program,” said Kunlei Liu, Associate Director for Research at UK CAER. “Our team is developing and demonstrating cost-effective and practical technologies for reducing and managing wastewater, benefitting Kentucky companies and strengthening Kentucky’s industrial sector.”

 

Flue-gas desulfurization (FGD) technology is used to remove sulfur dioxide from exhaust flue gas at fossil fuel power plants. FGD technology is an important environmental mitigation process, as it also captures portion of heavy metals created during power generation, including selenium, arsenic and mercury.

 

UK CAER’s project seeks to intensify the traditional water treatment process, thereby lowering the cost for industry, said Xin Gao, Senior Research Engineer at the Center, and the principle investigator for the funded project.

 

“This next-stage technology currently being developed at UK CAER has a potential to intensify and/or integrate the conventional wastewater treatment process,” said Gao. “If successful, this technology would significantly lower the cost for water treatment.”

 

This UK CAER project seeks to utilize electrocoagulation, flotation and nanofiltration – via membranes – to remove as many heavy metals and soluble salts from the water as possible, and then recycle that water into the system. This process will reduce the amount of fresh water needed and make landfilling those particulates easier.

 

As part of the project, the UK CAER research team will be evaluating the effectiveness of electrocoagulation and long-term operation of membrane filtration as well as the ability to consistently create “landfillable solids” while meeting government regulations.
