Tequila A.L. Harris, a professor in the George W. Woodruff School of Mechanical Engineering at Georgia Tech, leads energy and manufacturing initiatives at the Strategic Energy Institute. Her research explores the connectivity between the functionality of nano- to macro-level films, components, and systems based on their manufacture or design and their life expectancy, elucidating mechanisms by which performance or durability can be predicted. She uses both simulations and experimentation to better understand this connectivity.

By addressing complex, fundamental problems, Harris aims to make an impact on many industries, in particular energy (e.g., polymer electrolyte membrane fuel cells), flexible electronics (e.g., organic electronics), and clean energy (e.g., water), among others. 

Harris has experience in developing systematic design and manufacturing methodologies for complex systems that directly involve material characterization, tooling design and analysis, computational and analytical modeling, experimentation, and system design and optimization. Currently, her research projects focus on investigating the fundamental science associated with fluid transport, materials processing, and design issues for energy/electronic/environmental systems. Below is a brief Q&A with Harris, where she discusses her research and how it influences the energy and manufacturing initiatives at Georgia Tech.

• What is your field of expertise and at what point in your life did you first become interested in this area?

In graduate school, I aimed to become a roboticist but shifted my focus after realizing I was not passionate about coding. This led me to explore manufacturing, particularly scaled manufacturing processes that transform fluids into thin films for applications in energy systems. Subsequently, my expertise is in coating science and technology and manufacturing system development. 

• What questions or challenges sparked your current energy research? What are the big issues facing your research area right now?

We often ask how we can process materials more cost-effectively and create complex architectures that surpass current capabilities. In energy systems, particularly with fuel cells, reducing the number of manufacturing steps is crucial, as each additional step increases costs and complexity. As researchers, we focus on understanding the implications of minimizing these steps and how they affect the properties and performance of the final devices. My group studies these relationships to find innovative manufacturing solutions. A major challenge in the manufacture of materials lies in scaling efficiently while maintaining performance and keeping costs low enough for commercial adoption. This is a pressing issue, especially for enabling technologies such as batteries, fuel cells, and flexible electronics needed for electric vehicles, where the production volumes are on the order of billions per year. 

• What interests you the most in leading the research initiative on energy and manufacturing? Why is your initiative important to the development of Georgia Tech’s energy research strategy?

What interests me most is the inherent possibility of advancing energy technologies holistically, from materials sourcing and materials production to public policy. More specifically, my interests are in understanding how we can scale the manufacture of burgeoning technologies for a variety of areas (energy, food, pharmaceuticals, packaging, and flexible electronics, among others) while reducing cost and increasing production yield. In this regard, we aim to incorporate artificial intelligence and machine learning in addition to considering limitations surrounding the production lifecycle. The challenges that exist to meet these goals cannot be done in a silo but rather as part of interdisciplinary teams who converge on specific problems. Georgia Tech is uniquely positioned to make significant impacts in the energy and manufacturing ecosystem, thanks to our robust infrastructure and expertise. With many manufacturers relocating to Georgia, particularly in the "energy belt" for EVs, batteries, and recycling facilities, Georgia Tech can serve as a crucial partner in advancing these industries and their technologies.

• What are the broader global and social benefits of the research you and your team conduct on energy and manufacturing?

The global impact of advancing manufacturing technologies is significant for processing at relevant economy of scales. To meet such demands, we cannot always rely on existing manufacturing know-how.  The Harris group holds the intellectual property on innovative processes that allow for the faster fabrication of individual or multiple materials, and that exhibit higher yields and improved performance than existing methods. Improvements in manufacturing systems often result in reduced waste, which is beneficial to the overall materials development ecosystem. Another global and societal benefit is workforce development. The students on my team are well-trained in the manufacture of materials using tools that are amenable to the most advanced and scalable manufacturing platform, roll-to-roll manufacturing, with integrated coating and printing tools. This unique skill set equips our students to thrive and become leaders in their careers.

• What are your plans for engaging a wider Georgia Tech faculty pool with the broader energy community?

By leveraging the new modular pilot-scale roll-to-roll manufacturing facility that integrates slot die coating, gravure/flexography printing, and inkjet printing, I plan to continue reaching out to faculty and industrial partners to find avenues for us to collaborate on a variety of interdisciplinary projects. The goal is to create groups that can help us advance materials development more rapidly by working as a collective from the beginning, versus considering scalable manufacturing pathways as an afterthought. By bringing interdisciplinary groups (chemists, materials scientists, engineers, etc.) together early, we can more efficiently and effectively overcome traditional delays in getting materials to market or, worse, the inability to push materials to market (which is commonly known as the valley of death). This can only be achieved by dismantling barriers that hinder early collaboration. This new facility aims to foster collaborative work among stakeholders, promoting the integrated development and characterization of various materials systems and technologies, and ultimately leading to more efficient manufacturing practices.

• What are your hobbies? 

I enjoy cooking and exploring my creativity in this space by combining national and international ingredients to make interesting and often delicious fusion cuisines. I also enjoy roller skating, cycling, and watching movies with my family and friends. 

• Who has influenced you the most?

From a professional standpoint, my research team influences me the most. After I present them with a problem, they are encouraged and expected to think beyond our initial starting point.  This ability to freely think and conceive of novel solutions sparks many new ideas on which to build future ideas. The best cases have kept me up at night, inspiring me to think about how to approach new problems and funding opportunities. I carry their experiences and challenges with me. Their influence on me is profound and is fundamentally why I am a professor.

Southern Company, Georgia Institute of Technology (Georgia Tech), Smart Wires, and other partners have announced that they are collaborating on a new U.S. Department of Energy-funded project. Scheduled for 2025, the project will jointly implement advanced power flow control (APFC) and dynamic line rating (DLR) technologies to support the connection of renewable energy sources and new demand more quickly.

This project, led by the Georgia Tech Center for Distributed Energy with professor Deepak Divan as Principal Investigator, was selected by the U.S. Department of Energy in November 2021 as one of four projects to receive funding for grid enhancing technologies (GETs) that improve grid reliability, optimize existing grid infrastructure, and support the connection of renewable energy. It will use Smart Wires’ APFC solution— SmartValve™—in a mobile deployment combined with its DLR software—SUMO—and also develop control algorithms that improve and fine-tune how these solutions can work in synergy to optimize use of the grid. 

“The launch of this innovative project represents an important step toward more efficient and reliable integration of cleaner energy sources,” said Tim Lieuwen, interim executive vice president for Research at Georgia Institute of Technology. “This collaboration allows us to identify, develop and test new ways to manage the power grid in Georgia by co-deploying APFC and DLR technologies.” 

While the effectiveness of these solutions is well documented in multiple third-party reports, such as RMI’s GETting Interconnected in PJM, this project will be the first large-scale implementation of both technologies together. It will specifically examine their combined impact and result in the development of design control algorithms to unlock the combined power of these solutions and maximize their efficiency.  

SUMO identifies when lines have spare capacity based on real-time weather conditions, while SmartValves can redirect power flows to quickly utilize this spare capacity. This also applies in reverse, with SUMO identifying when the dynamic ratings of lines are less than the static rating. If it’s a hot day, for example, SmartValves can redirect power flows away from these circuits to others with capacity, reducing the risk of system faults while improving operational safety.   

The mobile deployment of SmartValves can be installed and in-service within one week. This provides a rapidly deployable solution that avoids extended outages and can be easily moved between sites as system needs evolve over time. 

“We’re delighted to provide both SmartValves and SUMO in this project to move the dial in terms of deploying multiple GETs in synergy and optimizing their use,” said Joaquin Peirano, General Manager for the Americas at Smart Wires. “The commitment of utilities like Southern Company to get the most from their existing grid with GETs, combined with the positive regulatory developments such as FERC’s recent Order 1920, positions the U.S. to capture the full value these technologies can provide on transmission grids.”  

The project will be delivered in 2025 and will involve a one-year performance period to provide Southern Company with operational experience that can be shared with other utilities and pave the way for greater use of GETs in the U.S.

A newly designed soil-powered fuel cell that could provide a sustainable alternative to batteries was recognized as an honorable mention in the annual Fast Company Innovation by Design Awards.

Terracell is roughly the size of a paperback book and uses microbes found in soil to generate energy for low-power applications. 

Previous designs for soil microbial fuel cells required water submergence or saturated soil. Terracell can function in soil with a volumetric water content of 42%

Terracell placed in Fast Company’s list of the best sustainability-focused designs of 2024.

Researchers at Northwestern University lead the multi-institution research team that designed Terracell.

Josiah Hester, an associate professor in Georgia Tech's School of Interactive Computing who previously worked at Northwestern, directs the Ka Moamoa Lab, where the project was conceived. 

The team includes researchers from Northwestern, Georgia Tech, Stanford, the University of California-San Diego, and the University of California-Santa Cruz.

Their research was published in January in the Proceedings of the Association for Computing Machinery on Interactive, Mobile, Wearable, and Ubiquitous Technologies. The researchers will also present this work at the ACM international joint conference on Pervasive and Ubiquitous Computing (Ubicomp), Oct. 5-9.

According to the Fast Company website, the Innovation by Design Awards recognize “designers and businesses solving the most crucial problems of today and anticipating the pressing issues of tomorrow.” Winners are published in Fast Company Magazine and are honored at the Fast Company Innovation Festival in the fall.

“Terracell could reduce e-waste and extend the useful lifetime of electronics deployed for agriculture, environmental monitoring, and smart cities,” Hester said. “We were honored to be recognized for the design innovation award. It is a testament to the promise of sustainable computing and our hope for a more sustainable world.”

Whether it’s developing new products, reducing costs, or increasing accessibility, innovations in manufacturing stand to improve the lives of companies and consumers alike. Georgia Tech recently took another step toward ensuring those innovations make it from lab to market with the launch of a Modular Pilot Scale Roll-to-Roll Manufacturing Facility. 

“As researchers develop new materials, one of the key aspects we’re missing is how to make them at scale. This is a major oversight because if we can’t make them at scale, we can’t transition from basic research to commercialization,” said Tequila Harris, a professor in the George W. Woodruff School of Mechanical Engineering. “With this new facility, we can prove our discoveries beyond lab-scale studies — and can go from materials innovation to product development at scale.”

Led by Harris, the new facility is the result of a partnership between the Georgia Tech Manufacturing Institute(GTMI), the Strategic Energy Institute, and the Woodruff School. As a pilot facility, it will serve as a testbed for scaling up manufacturing research open for Georgia Tech researchers as well as academic, government, and industry partners around the world.

“The larger vision I see at Georgia Tech involves innovation in manufacturing for large-scale industries,” said Georgia Tech’s Interim Executive Vice President for Research Tim Lieuwen at the facility’s unveiling event on Sept. 19. “It’s crucial that we’re innovating in basic science and technology, but we also need to be innovating in large-scale manufacturing.”

Roll-to-roll (R2R) manufacturing transforms flexible rolls of substrate materials, such as paper, metal foils, and plastics, into more complex, transportable rolls upon coating the surface with one or more fluids, such as inks, suspensions, and solutions, which are subsequently dried or cured on the base substrate. Its high yield and efficiency make R2R an ideal method for the sustainable, large-scale production of components for solar cells, batteries, flexible electronics, and separations — all industries that have expanded in Georgia in recent years.

“As a state institution, we’re ultimately here to serve our state,” said Lieuwen, who is also Regents’ Professor and David S. Lewis Jr. Chair in the Daniel Guggenheim School of Aerospace Engineering. “We’re seeing Georgia emerge as the national leader in terms of recruiting corporate investments in this space and in industries that will be served by this facility.”

Roll-to-Roll Innovations

The R2R process is similar to the production of newspapers, where a large roll of blank paper goes through a series of rollers printing text and photos. “The roll-to-roll aspect is the process of using a specialized tool to force fluid onto a moving surface,” says Harris. It’s one of the fastest-growing methods for producing thin film materials — photovoltaics used in solar cells, transistors in flexible electronics, and micro-batteries, for example — at a large scale. 

Harris’s group works to develop novel manufacturing tools, with a particular focus on understanding and improving the dynamics of thin film manufacturing to increase efficiency and minimize waste. Her group is particularly interested in slot die coating, an R2R technique where a liquid material is precisely deposited onto a substrate through a narrow slot. With the new pilot facility, researchers like Harris will be able to take their work to the next level.

“Slot die coating on a roll-to-roll can handle the broadest viscosity range of most coating methods. Therefore, you can process a lot of different materials very quickly and easily,” says Harris. “It’s one of the fastest-growing technologies in the U.S. — and currently, this is the most advanced modular pilot scale facility at an academic university in the United States.”

“Georgia Tech is way ahead of the curve in terms of our facilities,” says GTMI Executive Director and Regents’ Professor Thomas Kurfess. “This will grow our capability in the battery area, membranes, flexible electronics, and more to allow us to support the development of new technologies.”

“As technologies around cleantech continue to advance at an unprecedented pace, pilot manufacturing facilities provide a critical bridge between innovative benchtop research and commercial-scale production and manufacturing,” says Christine Conwell, interim executive director of the Strategic Energy Institute. “We are excited about the opportunities this R2R facility will provide to the Georgia Tech energy community and our industry partners.”
