The Center for Sustainable Communities Research and Education (SCoRE — formerly SLS), in collaboration with the Strategic Energy Institute (SEI), the Brook Byers Institute for Sustainable Systems (BBISS), the Renewable Bioproducts Institute (RBI), and the Social Equity and Environmental Engineering Lab (SEEEL), launched the Energy Equity, Environmental Justice, and Community Engagement Faculty Fellows Program in November 2023. In this program, Georgia Tech faculty learn how to work with communities, bringing together their academic knowledge and the local expertise of communities that has been developed through lived experience and long-standing social action.

The inaugural fellows include 24 Georgia Tech faculty from five Colleges, as well as a faculty colleague from Georgia Gwinnett College and a partner from the Southeast Energy Efficiency Alliance, who are building relationships with each other and with community partners in the areas of energy equity and environmental justice. Since the launch, they have engaged in a wide array of events, including community benefit and development workshops, site visits to community-based organizations across the Atlanta region, and university-community gatherings and symposia.

The program is expected to result in both collective and individual deliverables. Collective deliverables include the development of network mapping tools to facilitate collaborations inside and outside Georgia Tech, a set of principles for conducting community-engaged research, a reflective essay on faculty training for community-engaged research, and ideas for future activities to facilitate university-community and interdisciplinary team formation. Fellows individually determine their deliverables, which run the gamut from exploring partnerships for a specific research project to writing a societal impact statement for a tenure package.

More broadly, the program aims to grow Georgia Tech’s collaborative expertise in community-engaged research by forming a supportive network of faculty interested in community-engaged sustainability research and education.

Sustainable energy sources and environmental justice go hand in hand. Although such technologies aim to minimize environmental impacts of modern societies, without considering issues of environmental justice and energy equity, these solutions can inadvertently perpetuate disparities by disproportionately benefiting certain communities while harming others. Bridging the gap between technological advancements and community benefits is paramount to creating an equitable energy future for all.

This program provides a unique opportunity to explore these interconnections, enhancing my knowledge in integrating community values and concerns into my research on alternative fuels and renewable energy sources. I am particularly excited about the hands-on approach of the program, which emphasizes listening sessions and workshops, allowing fellows to gain direct insights from various stakeholders. I hope that, through active participation in these sessions, I can further my understanding of the challenges faced by local communities and incorporate these insights into actionable solutions in my research.

In my project, I'm in a group crafting a reflective essay about our experiences with Community Engaged Research training. Our goal is to translate the insights gained from this pilot program into a publishable piece. Additionally, I'm acquiring valuable insights into the development of Broader Impact Statements and Community Benefits Plans, crucial parts of proposals for securing federal funding from NSF and DoE, respectively.

The fellowship program has been a fantastic experience. I never imagined how much I would learn from this program about properly engaging with communities. As researchers, we might think we want to hear the needs that communities face to provide them with solutions. That is different than the way community-driven research should work. I’ve learned that researchers need to gain the communities’ trust, be present and participate in their events, and, more importantly, work at their pace and for their interests rather than push our research agendas for our professional benefit. I know there is still a lot more I must continue learning, but what I’ve learned so far has been an eye-opener that is making me rethink how to approach my research and its social aspect.

My project focuses on the social performance of supply chains, and I am seeking to put more emphasis on the “social” part of my research by making it more community-driven. That is why I applied for the fellowship. I am advancing two current projects as part of the fellowship. One relates to increasing food accessibility to vulnerable populations via community-driven freight transportation solutions. I want to bring food closer to people and do it by co-designing solutions with the communities. The second project relates to forming a team to pursue research on enhancing community resilience to extreme weather events for the mobility of people and goods. The fellowship and a Sustainability Next seed grant from BBISS are helping me move forward with this project.

In January, Georgia Tech researchers were awarded three grants as a part of the Department of Energy’s Industrial Efficiency and Decarbonization multi-topic funding. The awards include 49 high-impact, applied research, development, and pilot-scale technology validation and demonstration projects that will reduce energy usage and greenhouse gas emissions in conjunction with cross-sector industrial decarbonization approaches.

The Georgia Tech funding includes a project, in the topic area of Decarbonizing Forest Products, on innovative refining, paper forming, and drying to eliminate CO2 emissions from paper machines. Funded at $3.1 million, the project is led by Carson Meredith, professor and James Harris Faculty Fellow in the School of Chemical and Biomolecular Engineering and executive director of the Renewable Bioproducts Institute (RBI). Collaborators include co-PI Cyrus Aidun, professor of mechanical engineering; Patritsia Stathatou, research scientist at RBI; and Aruna Weerasakura, senior research engineer. External collaborators include Fort Valley State University, the National Renewable Energy Laboratory, and several RBI member companies.

Meredith’s project focuses on decarbonization in energy-intensive drying, paper forming, and pulping processes and will combine recent deflocculation breakthroughs in fiber refining with low-water, multiphase paper forming. The innovations will facilitate the cost-effective implementation of advanced electrical drying technologies in the paper industry. By taking advantage of the increasing fraction of non-fossil electricity in the U.S., electrified drying, if implemented partially (50%), has the potential to reduce the generation of non-biogenic emissions by over 10 million metric tons of CO2e annually.

"I am excited because the new project will utilize the multiphase forming laboratory that is under construction in the Paper Tricentennial Building, representing the first major expansion in lab space there since the 1990s,” said Meredith.

Valerie Thomas, the Anderson-Interface Chair of Natural Systems and professor of industrial and systems engineering and public policy, is a co-PI in a $1.45 million project titled “Mild Co-Solvent Pulping to Decarbonize the Paper and Forest Products Sector,“ led by the University of California, Riverside.

Thomas’ project, also under the topic area of Decarbonizing Forest Products, aims to enhance Co-solvent Enhanced Lignocellulosic Fractionation (CELF) technology into a more environmentally sustainable alternative to traditional kraft pulping. CELF technology will be applied to optimize the production of dissolving pulp used in the manufacturing of extruded textile fibers and will also produce dissolving lignin as a by-product that can serve as a natural resin binder or a renewable ingredient for producing industrial adhesives and binders. This technology has the potential to reduce carbon intensity by 50 – 75% and operating costs by 10 – 20%.

Tim Lieuwen, David S. Lewis Jr. Chair and professor in aerospace engineering and executive director of the Strategic Energy Institute, is co-PI along with Vishal Acharya, principal research engineer and Benjamin Emerson, principal research engineer at Georgia Tech in a $3.25 million project titled “Omnivore Combustion System,” led by GTI Energy, an Illinois-based technology company.

Lieuwen’s project, under the topic area of Low-Carbon Fuels Utilization R&D, will design and demonstrate a scaled, adaptable omnivore combustion system (OCS) that can accommodate a continuously varying blend of low-carbon fuels with ultra-low nitrous oxide emissions, including natural gas-hydrogen blends, syngas, and biogas. The project will demonstrate a full-scale OCS for at least 100 hours and will focus on three aspects — improving performance, operation stability and safety, and fuel flexibility — and can potentially be used for industrial furnace applications in high carbon-emitting industries.

“The industrial sector is large in both its significance for our economy and its negative climate impacts, and each of these projects addresses significant challenges for the decarbonization of this critical sector,” Lieuwen said.

The projects are part of DOE’s Technologies for Industrial Emissions Reduction Development (TIEReD) Program, which invests in fundamental science, research, development, and initial pilot-scale demonstrations projects to decarbonize the industrial sector — currently responsible for a third of the nation’s greenhouse gas emissions.

Matthew McDowell, Woodruff Faculty Fellow and associate professor in the George W. Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering and initiative lead for energy storage at the Strategic Energy Institute, has received $1.3 million in funding through the Pioneering Railroad, Oceanic, and Plane Electrification with 1K energy storage systems (PROPEL-1K) program. Aimed at accelerating the electrification of the aviation, railroad, and maritime transportation sectors, PROPEL-1K is one of the latest ARPA-E grants with projects to develop energy storage systems that can achieve over 1,000 watt-hour per kilogram and 1,000 watt-hour per liter. These technologies will improve energy density fourfold over current technologies.

Inspired by fuel injectors in internal combustion engines and conventional flow batteries, McDowell’s project will advance an alkali hydroxide triple phase flow battery to enable reversible operation of ultrahigh-energy density battery chemistries. The project’s proposed design will increase energy density by leveraging innovative pumping and handling of molten alkali metal and hydroxide species to maximize the volume of reactants over inactive components.

McDowell will work with Asegun Henry, associate professor in the Department of Mechanical Engineering at the Massachusetts Institute of Technology (MIT). Prior to MIT, Henry was an assistant professor in the George W. Woodruff School of Mechanical Engineering at Georgia Tech.

Created in 2007, the Advanced Research Projects Agency-Energy (ARPA-E) in the Department of Energy advances high-potential, high-impact energy technologies. The agency focuses on transformational energy projects that can be meaningfully advanced with a small amount of funding over a defined period through a streamlined awards process that enables quick action and catalyzes cutting-edge areas of energy research.

Energy is everywhere, affecting everything, all the time. And it can be manipulated and converted into the kind of energy that we depend on as a civilization. But transforming this ambient energy (the result of gyrating atoms and molecules) into something we can plug into and use when we need it requires specific materials.

These energy materials — some natural, some manufactured, some a combination — facilitate the conversion or transmission of energy. They also play an essential role in how we store energy, how we reduce power consumption, and how we develop cleaner, efficient energy solutions.

“Advanced materials and clean energy technologies are tightly connected, and at Georgia Tech we’ve been making major investments in people and facilities in batteries, solar energy, and hydrogen, for several decades,” said Tim Lieuwen, the David S. Lewis Jr. Chair and professor of aerospace engineering, and executive director of Georgia Tech’s Strategic Energy Institute (SEI).

That research synergy is the underpinning of Georgia Tech Energy Materials Day (March 27), a gathering of people from academia, government, and industry, co-hosted by SEI, the Institute for Materials (IMat), and the Georgia Tech Advanced Battery Center. This event aims to build on the momentum created by Georgia Tech Battery Day, held in March 2023, which drew more than 230 energy researchers and industry representatives.

“We thought it would be a good idea to expand on the Battery Day idea and showcase a wide range of research and expertise in other areas, such as solar energy and clean fuels, in addition to what we’re doing in batteries and energy storage,” said Matt McDowell, associate professor in the George W. Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering (MSE), and co-director, with Gleb Yushin, of the Advanced Battery Center.

Energy Materials Day will bring together experts from academia, government, and industry to discuss and accelerate research in three key areas: battery materials and technologies, photovoltaics and the grid, and materials for carbon-neutral fuel production, “all of which are crucial for driving the clean energy transition,” noted Eric Vogel, executive director of IMat and the Hightower Professor of Materials Science and Engineering.

“Georgia Tech is leading the charge in research in these three areas,” he said. “And we’re excited to unite so many experts to spark the important discussions that will help us advance our nation’s path to net-zero emissions.”

Building an Energy Hub

Energy Materials Day is part of an ongoing, long-range effort to position Georgia Tech, and Georgia, as a go-to location for modern energy companies. So far, the message seems to be landing. Georgia has had more than $28 billion invested or announced in electric vehicle-related projects since 2020. And Georgia Tech was recently ranked by U.S. News & World Report as the top public university for energy research.

Georgia has become a major player in solar energy, also, with the announcement last year of a $2.5 billion plant being developed by Korean solar company Hanwha Qcells, taking advantage of President Biden’s climate policies. Qcells’ global chief technology officer, Danielle Merfeld, a member of SEI’s External Advisory Board, will be the keynote speaker for Energy Materials Day.

“Growing these industry relationships, building trust through collaborations with industry — these have been strong motivations in our efforts to create a hub here in Atlanta,” said Yushin, professor in MSE and co-founder of Sila Nanotechnologies, a battery materials startup valued at more than $3 billion.

McDowell and Yushin are leading the battery initiative for Energy Materials Day and they’ll be among 12 experts making presentations on battery materials and technologies, including six from Georgia Tech and four from industry. In addition to the formal sessions and presentations, there will also be an opportunity for networking.

“I think Georgia Tech has a responsibility to help grow a manufacturing ecosystem,” McDowell said. “We have the research and educational experience and expertise that companies need, and we’re working to coordinate our efforts with industry.”

Marta Hatzell, associate professor of mechanical engineering and chemical and biomolecular engineering, is leading the carbon-neutral fuel production portion of the event, while Juan-Pablo Correa-Baena, assistant professor in MSE, is leading the photovoltaics initiative.

They’ll be joined by a host of experts from Georgia Tech and institutes across the country, “some of the top thought leaders in their fields,” said Correa-Baena, whose lab has spent years optimizing a semiconductor material for solar energy conversion.

“Over the past decade, we have been working to achieve high efficiencies in solar panels based on a new, low-cost material called halide perovskites,” he said. His lab recently discovered how to prevent the chemical interactions that can degrade it. “It’s kind of a miracle material, and we want to increase its lifespan, make it more robust and commercially relevant.”

While Correa-Baena is working to revolutionize solar energy, Hatzell’s lab is designing materials to clean up the manufacturing of clean fuels.

“We’re interested in decarbonizing the industrial sector, through the production of carbon-neutral fuels,” said Hatzell, whose lab is designing new materials to make clean ammonia and hydrogen, both of which have the potential to play a major role in a carbon-free fuel system, without using fossil fuels as the feedstock. “We’re also working on a collaborative project focusing on assessing the economics of clean ammonia on a larger, global scale.”

The hope for Energy Materials Day is that other collaborations will be fostered as industry’s needs and the research enterprise collide in one place — Georgia Tech’s Exhibition Hall — over one day. The event is part of what Yushin called “the snowball effect.”

“You attract a new company to the region, and then another,” he said. “If we want to boost domestic production and supply chains, we must roll like a snowball gathering momentum. Education is a significant part of that effect. To build this new technology and new facilities for a new industry, you need trained, talented engineers. And we’ve got plenty of those. Georgia Tech can become the single point of contact, helping companies solve the technical challenges in a new age of clean energy.”

A regional consortium led by the Georgia Institute of Technology, the University of Georgia, and Georgia State University, in collaboration with the Georgia Mining Association, will host an inaugural workshop on Georgia partnerships for Essential Minerals (GEMs).

The one-day workshop is planned for Thursday, Feb. 1, at the University of Georgia Hotel and Conference Center and is expected to be the first in a series of critical mineral conversations hosted in rotation by the partner institutions. The event will bring together 40 participants from academia, industry, and government to discuss the opportunities and challenges around critical mineral supplies in the state and in the nation. 

The GEMs workshop is driven by the compelling needs around domestic critical mineral supply for the energy and transportation sectors, and by the potentially significant rare earth element resources available in the state of Georgia. The workshop will couple the research capabilities of the three Georgia R1 research universities and the mature mining industry in Georgia to solve the challenges around this issue.

It will engage all stakeholders with interests in resource exploration, technology development, energy and environmental sustainability, economic development, regulatory compliance, and workforce development toward achieving national security independence for critical mineral supply. The first workshop will focus on the production of the critical mineral resource, rare earth elements (REE), from kaolin mine tailings, overburden, and other potential processing streams. Other areas of REE production may also be considered.

The goal of the workshop is to produce a statement of outcomes regarding the current state of knowledge, opportunities, challenges, and possible pathways for GEMs. It will also serve as a catalyst to drive conversations among the key stakeholders to make an impact in GEMs, including developing university-industry-government partnership grants, internships, sponsored research, and training opportunities for the current and next generation of Georgia residents. These relationships will play an important role in creating reliable domestic supplies of critical minerals.

About This Project
The Energy, Policy, and Innovation Center faculty affiliates Dylan Brewer, Daniel Dench, and Interim Director Laura Taylor published an article titled "Advances in Causal Inference at the Intersection of Air Pollution and Health Outcomes." The authors compare the methods used in the epidemiology literature with the causal inference framework used in economics in analyzing the effect of air pollution on health outcomes.

Determining the quality and accuracy of the evidence linking air pollution to human health has been a challenge for research in this area.

Each academic discipline has a unique lens through which they view and solve a problem, which may result in different conclusions being drawn from the same data. While studies that involve randomization across populations can provide evidence and are widely used in medical research, exposures to everyday air pollution cannot be randomized by a researcher.

Many existing studies exploring the health impacts of air pollution rely on establishing correlations between pollutants and health outcomes. However, correlations do not imply causation and can lead to bad policy. In this study, the EPICenter affiliates reviewed methodological contributions made by economists to determine if using statistical methods to the study of the health effects of air pollution can contribute to more robust and reliable findings.

To understand the difficulty researchers face, consider a typical air pollution study that collects health data of residents living near a pollution source, such as a coal-fired power plant. The data would be used to see if there is an increased incidence of adverse health outcomes such as asthma, chronic obstructive pulmonary disease, or cardiopulmonary disease. However, many factors can create a confounding effect on the final results if the researcher doesn’t take them into consideration. For instance, the power plant may have been built in a low-income location, or lower-income households may have moved near the power plant to take advantage of lower rent or property prices. This may conflate the effect of income and air pollution on health.

Simple schematic documenting the path of air pollution from emissions to outcomes. This review discusses the challenges of measuring how emissions of pollutants (step 1) disperse through the air (step 2) to become eventual exposures (step 3) and health outcomes (step 4).

Economists promote the use of natural experiments to overcome confounding factors. Natural experiments mimic familiar laboratory experiments. For instance, in the power plant example, random variation in wind direction would result in some households being randomly more exposed to air pollution, regardless of income. By taking advantage of this randomization, researchers can compare differences in a particular health outcome between those more exposed and less exposed, while overcoming confounding effects such as income, and move one step closer toward improving our understanding of the relationship between air pollution and adverse health outcomes.

The authors conclude by emphasizing the need for creating multidisciplinary teams, including economists, air-quality modelers, and public health and medical researchers. “While one may not think of economists as a natural contributor to this line of research, the analytical framework honed by economists over decades can contribute important expertise to the design of these types of studies,” Taylor concluded, “and result in better evidence for policymakers.”
