Georgia Tech Launches Quadrant-i, a New Unit to Enhance Research Commercialization

Georgia Tech's Office of Commercialization introduces Quadrant-i, a new unit dedicated to helping faculty, researchers, and students translate their research into startups.

The name is inspired by Pasteur’s quadrant in the Daniel Stokes innovation-impact model and will emphasize the translation of deep scientific research into products. (See more information about Pasteur’s quadrant here.)

Quadrant-i will join the other units in commercialization — the Office of Technology Licensing, VentureLab, and CREATE-X — in making Georgia Tech the premier campus for startups and commercialization.

“As we grow our efforts toward delivering impact through commercialization, creating a unit that is solely focused on helping our faculty, students, and researchers launch startups based on their research is essential,” said Raghupathy “Siva” Sivakumar, vice president of Commercialization and chief commercialization officer.

The functions of Quadrant-i have historically been supported by VentureLab, a national leader in entrepreneurship training and research. The reorganization will also allow VentureLab to amplify its impact in making Georgia Tech a thought leader for entrepreneurship.

Quadrant-i will be a comprehensive resource for the thriving research community on campus, facilitating the journey from innovations to impact. The unit will offer programs, resources, and services tailored to expedite and enhance the commercialization process, including:

• Advocating for policy changes and incentive structures to foster a culture of impact.
• Securing non-dilutive grant funding.
• Navigating conflicts of interest to maintain research integrity.
• Providing mentorship on the business aspects of innovation.
• Interfacing with customers, investors, and mentors.
• Launching startups with essential resources and support.

A search is currently underway for a director, who will report to Sivakumar.

The Office of Commercialization invites faculty, researchers, students, investors, mentors, industry leaders, and innovators to collaborate with Quadrant-i and learn more about its programs and services.

A new study by Associate Professor Omar Isaac Asensio and a team of students in Georgia Tech’s School of Public Policy finds that federal housing policies accelerate energy efficiency participation among low and moderate-income households — even when those policies don’t directly address energy efficiency. 

The research, published in Nature Sustainability, shows how community development block grants from the U.S. Department of Housing and Urban Development (HUD) generated an average of 5% to 11% energy savings in economically burdened households in Albany. The savings equate to the cost of roughly two months of groceries per household per year. 

"These housing participants who didn't come in thinking about energy efficiency saved anywhere from $75 to $482 per year in energy bills," Asensio said. "Those are meaningful savings that really impact people. So, we ended up finding very significant hidden social benefits from these policies that were previously unknown." 

The findings are surprising because HUD grants do not specifically target energy efficiency or sustainability measures in exchange for governmental assistance. Instead, they are given at the discretion of the local government to residents facing housing emergencies such as deteriorating roofs or broken HVAC systems in the hot summer. Because of the high amount of deferred maintenance in these homes, the fixes have a spillover effect of significantly reducing energy use — for example, by adopting more efficient technologies and bringing structures up to building codes — and saving money for people who receive them.  

The multidisciplinary research team in Asensio’s Data Science & Policy Lab, including current and former Public Policy students Olga Churkina and Becky D. Rafter and industrial engineering alumna Kira E. O'Hare, also found that the cost-effectiveness of housing-based interventions rivals standalone energy efficiency policies, offering a promising alternative for reaching marginalized communities.  

"For decades, we’ve struggled to get meaningful participation with conventional policies in these lower and moderate-income communities, including among renters and people in multi-family homes,” Asensio said. "Using housing block grants as an entry strategy to drive efficiency is an important policy innovation.” 

With support from the National Science Foundation, ESRI, Inc., and the Georgia Smart Communities Challenge, Asensio and his co-authors spent nearly four years collecting, cleaning, and combining Albany's previously siloed city data into one community analytics repository. They linked records for 5.9 million utility bills per month from 2004 to 2019, allowing them to see long-run impacts of policy intervention, energy consumption, and payments by household — an uncommonly granular level of data.  

"Overall, HUD-funded block grants in Albany reduced electricity use by 4.72 million kilowatt hours over the study period versus the control group," the researchers wrote. "The reduction in non-baseload emissions is equivalent to 3.70 million pounds of coal not being burned or the carbon sequestered by 3,695 acres of forest." 

Asensio's research is timely because the Southeast has some of the country's highest energy-burdened households. In the U.S., spending over 6% of net income on energy is considered a burden. In Albany, renters' and homeowners' energy costs can surpass ten or even 20% of household budgets, Asensio said, and many housing applicants are elderly and on fixed incomes.  

Unlike conventional energy initiatives that are reliant on self-selection, housing programs can provide a more equitable and localized strategy. That's because "most of the standalone policies for energy efficiency have two main outcomes," Asensio said. "First, the programs generally attract more affluent and informed homeowners, in which case, questions arise as to whether this might be a good use of public funds. Second, when these policies are restricted to certain income eligibility limits, we don't get enough participation from lower income residents for a long list of reasons. So, reaching low- and moderate-income households has become a fundamental challenge." 

In contrast, housing block grants naturally target a broader range of residents with high energy burdens and help circumvent the problem of low participation. Rather than trying to market an energy-saving offer to people who aren't interested or are distrustful of the government, HUD grants have long waiting lists.  

"There are thousands and thousands of communities that look very much like Albany within and outside of major metro areas,” Asensio said. "This is a relatively untapped opportunity for driving energy efficiency within households who may not necessarily have an awareness of or interest in energy efficiency measures.”  

The paper, “Housing Policies and Energy Efficiency Spillovers in Low and Moderate Income Communities,” was published online in Nature Sustainability on March 18. It is available at https://doi.org/10.1038/s41893-024-01314-w. This work was partially supported by awards from the National Science Foundation (Award No. 1945332), ESRI, Inc., the Georgia Smart Communities Challenge, and the Institute for the Study of Business in Global Society at Harvard Business School. 

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, along with Vishal Acharya, principal research engineer and Benjamin Emerson, principal research engineer at Georgia Tech is a co-PI 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 G. 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.

Georgia Tech is developing a new artificial intelligence (AI) based method to automatically find and stop threats to renewable energy and local generators for energy customers across the nation’s power grid.

The research will concentrate on protecting distributed energy resources (DER), which are most often used on low-voltage portions of the power grid. They can include rooftop solar panels, controllable electric vehicle chargers, and battery storage systems. 

The cybersecurity concern is that an attacker could compromise these systems and use them to cause problems across the electrical grid like, overloading components and voltage fluctuations. These issues are a national security risk and could cause massive customer disruptions through blackouts and equipment damage. 

“Cyber-physical critical infrastructures provide us with core societal functionalities and services such as electricity,” said Saman Zonouz, Georgia Tech associate professor and lead researcher for the project. 

“Our multi-disciplinary solution, DerGuard, will leverage device-level cybersecurity, system-wide analysis, and AI techniques for automated vulnerability assessment, discovery, and mitigation in power grids with emerging renewable energy resources.”

The project’s long-term outcome will be a secure, AI-enabled power grid solution that can search and protect the DER’s on its network from cyberattacks. 

“First, we will identify sets of critical DERs that, if compromised, would allow the attacker to cause the most trouble for the power grid,” said Daniel Molzahn, assistant professor at Georgia Tech. 

“These DERs would then be prioritized for analysis and patching any identified cyber problems. Identifying the critical sets of DERs would require information about the DERs themselves- like size or location- and the power grid. This way, the utility company or other aggregator would be in the best position to use this tool.”

Additionally, the team will establish a testbed with industry partners. They will then develop and evaluate technology applications to better understand the behavior between people, devices, and network performance.

Along with Zonouz and Molzahn, Georgia Tech faculty Wenke Lee, professor, and John P. Imlay Jr. chair in software, will also lead the team of researchers from across the country. 

The researchers are collaborating with the University of Illinois at Urbana-Champaign, the Department of Energy’s National Renewable Energy Lab, the Idaho National Labs, the National Rural Electric Cooperative Association, and Fortiphyd Logic. Industry partners Network Perception, Siemens, and PSE&G will advise the researchers. 

The work will be carried out at Georgia Tech’s Cyber-Physical Security Lab (CPSec) within the School of Cybersecurity and Privacy (SCP) and the School of Electrical and Computer Engineering (ECE). 

The U.S. Department of Energy (DOE) announced a $45 million investment at the end of February for 16 cybersecurity initiatives. The projects will identify new cybersecurity tools and technologies designed to reduce cyber risks for energy infrastructure followed by tech-transfer initiatives. The DOE’s Office of Cybersecurity, Energy Security, and Emergency Response (CESER) awarded $4.2 million for the Institute’s DerGuard project. 

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.”

Four researchers from the Georgia Institute of Technology — Alex Blumenthal, Juan-Pablo Correa-Baena, Chunhui Du, and Daniel Genkin — have received 2024 Sloan Research Fellowships, one of the highest honors for early-career faculty.

They are among the 126 researchers chosen from more than 1,000 nominations this year.  Fellows receive $75,000 over two years to advance their research.

"Sloan Research Fellowships are extraordinarily competitive awards involving the nominations of the most inventive and impactful early-career scientists across the U.S. and Canada,” said Adam F. Falk, president of the Alfred P. Sloan Foundation, which has awarded the fellowships since 1955.

Since then, 55 individuals from Georgia Tech have won fellowships, and it has become one of the most prestigious awards for young investigators and a predictor of future research success. For example, 57 Sloan Fellows have received a Nobel Prize and 71 have won the National Medal of Science.

Falk added, “We look forward to seeing how fellows take leading roles shaping the research agenda within their respective fields.”

Demand for critical minerals and rare earth elements is rapidly increasing as the world accelerates toward clean energy transitions. Concerns about price volatility, supply security, and geopolitics arise as reducing emissions and ensuring resilient and secure energy systems become increasingly crucial.  

 To address this important area, 45 participants from academia, government, industry, and national labs gathered at the University of Georgia for the inaugural Georgia partnerships for Essential Minerals (GEMs) Workshop. The workshop was the first in a series of critical mineral conversations planned by the collaborators of the workshop. The first GEMs Workshop focused on the critical mineral potential in Georgia’s kaolin mining industry.  

 Key workshop conveners included W. Crawford Elliott, associate professor of chemistry and geosciences at Georgia State University; Lee R. Lemke, secretary and executive vice president of the Georgia Mining Association; Paul A. Schroeder, professor in clay minerology at the University of Georgia; and Yuanzhi Tang, associate professor in the School of Earth and Atmospheric Sciences at Georgia Tech. 

 Representatives from more than 20 companies, the Environmental Protection Agency, U.S. Geological Survey, Georgia Environmental Protection Division, and Savannah River National Laboratory, as well as faculty members and students from Georgia’s three R1 universities participated in the day-long workshop. Speaker sessions and panel discussions addressed: 

• Developing a state and regional ecosystem demonstrating a critical mineral supply chain from resources to solutions to end users. 
• A strong emphasis on workforce training for this emerging industry.  
• Establishing a regional critical mineral consortium to facilitate resource exploration, characterization, processing, and utilization.
• Creating official industry-university collaborations that included internships, field trips, curricular training, R&D collaboration, and stakeholder liaisons. 

 Workshop organizers plan to reconvene in six months to continue conversations and build momentum on critical minerals research, from supplies to workforce training and beyond.
