WashU to lead $26 million decarbonization initiative To minimize the impact of man-made climate change, it is essential to significantly and rapidly decrease carbon dioxide emissions while simultaneously meeting the energy and manufacturing needs of a healthy and economically stable society. A powerhouse collaboration of universities and industry, led by the McKelvey School of Engineering at Washington University in St. Louis, is embarking on a bold plan to transform manufacturing toward zero or negative emissions by converting carbon dioxide ultimately into environmentally friendly chemicals and products that create a circular economy.

The Carbon Utilization Redesign for Biomanufacturing-Empowered Decarbonization (CURB) Engineering Research Center (ERC) is funded by a fiveyear, $26 million grant from the U.S. National Science Foundation(NSF). The award — one of only four the NSF awarded nationwide in 2024 — supports convergent projects that include research, education, commercialization, workforce development, and diversity and inclusion that will lead to societal change.

“The vision of CURB is as a vibrant global research and innovation ecosystem that transforms U.S. manufacturing by capturing and leveraging carbon dioxide emissions and thereby decreasing the human ecological footprint,” said Aaron F. Bobick, dean and the James M. McKelvey Professor in McKelvey Engineering.

“For McKelvey Engineering to lead this research project represents the increased sophistication of the school’s research and its ability to support an activity of this scale and in alignment with our strategic priorities.”

McKelvey Engineering brings its broad, unique experience with the nation’s first Department of Energy, Environmental & Chemical Engineering to lead the ambitious project in collaboration with prominent researchers at the University of Delaware, Prairie View A&M University and Texas A&M University.

Converting CO₂ to solid carbon yields benefits for batteries and more The Department of Energy (DOE) recently awarded $29 million in grants for “carbon management” technologies, including $1.5 million of those funds going to Xinhua Liang, professor of energy, environmental & chemical engineering in WashU’s McKelvey School of Engineering.

Previously, Liang received $2 million from the DOE to convert CO₂ to concrete products, and this continues that work, with a twist. Liang and his colleagues have developed a thermocatalytic process that could yield useful parts for increasingly ubiquitous lithium-ion batteries that power electric cars and other devices. Liang will fine-tune this process with his co-principal investigator, Miao Yu, a professor in the Department of Chemical and Biological Engineering at the University at Buffalo.

The grant will fund Liang’s development of a low-carbon process to convert CO₂ to valuable highquality carbon nanotubes (CNTs). These nanotubes have “similar properties as commercial CNTs,” noted Liang, making them not only useful as potential anodes in batteries but doing so at a much more affordable price, a key component to scaling up these technologies.

Novel electro-biodiesel a more efficient, cleaner option to existing alternatives

WashU scientists uncover hidden source of snow melt: dark brown carbon In a study recently published in npj Climate and Atmospheric Science, researchers at Washington University in St. Louis model how dark-brown carbon (d-BrC) – light absorbing, water insoluble organic carbon plays a much larger role as a snow-warming agent than previously recorded. It’s 1.6 times as potent a warmer compared to what researchers previously thought was the main culprit, black carbon.

In the Tibetan Plateau and other midlatitude regions, deposition of water insoluble organic carbon on snow have been previously recorded, “But nobody really looked under the hood to investigate their snow melting potential,” said Rajan Chakrabarty, a professor at WashU’s McKelvey School of Engineering.

Chakrabarty’s PhD student, Ganesh Chelluboyina, and Taveen Kapoor, a postdoctoral fellow, have spent the bulk of their time at WashU taking up that challenge. They liken d-BrC to an “evil cousin” of black carbon, and much like black carbon, wildfires deposit it upon snow caps like switching out a white t-shirt for dark brown poncho. When the snow loses its reflectivity and warms up, this increases surrounding air temperatures and further notches up the warming cycle.

The team plans to further document the real-world effects of d-BrC at work as they enter the experimental phase of research, dropping atomized water droplets into the top of a four-foot-tall chamber, creating snow, and depositing aerosols on it.

Joshua Yuan, the Lucy & Stanley Lopata Professor and chair of the Department of Energy, Environmental & Chemical Engineering in the McKelvey School of Engineering at Washington University in St. Louis, and Susie Dai, a MizzouForward Professor of Chemical and Biomedical Engineering at the University of Missouri, and their collaborators at Texas A&M University, have used electrocatalysis of carbon dioxide to create an electro-biodiesel that is 45 times more efficient and uses 45 times less land than soybean-based biodiesel production. Results of their work are published online in Joule Oct. 31, 2024.

“This research proves the concept for a broad platform for highly efficient conversion of renewable energy into chemicals, fuels and materials to address the fundamental limits of human civilization,” Yuan said. “This process could relieve the biodiesel feedstock shortage and transform broad, renewable fuel, chemical and material manufacturing by achieving independence from fossil fuel in the sectors that are fossil-fuel dependent, such as long-range heavy-duty vehicles and aircraft.”

Research news Altered carbon points toward sustainable manufacturing

cientists find new way global S air churn makes particles Researchers at Washington University in St. Louis have discovered a new mechanism that produces a large portion of particles in Earth’s atmosphere.

The research, published in Science was led by Jian Wang, professor and director of the Center for Aerosol Science and Engineering at WashU. The research team includes Lu Xu, assistant professor in WashU’s Department of Energy, Environmental & Chemical Engineering at the McKelvey School of Engineering and scientists from NASA, NOAA, NCAR and European universities.

The conventional thinking was that most particle formation occurs in cloud outflow regions, where clouds float into the upper troposphere and eventually evaporate. In that process, clouds are getting wrung out and most particles are removed by rain. As a result, the air in the outflow regions is clear and clean, leaving some gaseous molecules with nowhere to go but form new particles.

“However, using the data collected from NASA’s global-scale aircraft measurements, we found that most of the new particles are not formed in the outflow regions as previously thought,” Wang said.

While puzzling over this surprising observation, Wang and colleagues ended up discovering a whole different mechanism taking place when the mixing of stratospheric and tropospheric air results in conditions that are ripe for particle formation.

Sustainable technology to extract critical materials from coal-based resources Young-Shin Jun, professor of energy, environmental & chemical engineering in the McKelvey School of Engineering at Washington University in St. Louis, received a one-year, $500,000 grant from the U.S. Department of Energy (DOE) and $25,000 from WashU’s Consortium for Clean Coal Utilization for her work to extract rare earth elements (REEs) from coal. With the DOE’s support, Jun plans to develop novel technology to extract, recover and enrich REEs effectively from solid coal-based materials in a way that does not harm the environment.

Jun’s project builds on her previous research on harnessing the potential of supercritical fluids to extract REEs directly from coal fly ashes and uncombusted coal sustainably. By first characterizing the properties and structures of these coal-based materials, Jun plans to develop an innovative supercritical fluid-enabled extraction technology that optimizes the recovery process, enhancing efficiency while reducing waste and energy consumption to minimize environmental impact.

Feng Jiao, the Elvera and William R. Stuckenberg Professor in in the McKelvey School of Engineering at Washington University in St. Louis, developed a twostep process to convert carbon dioxide (CO₂) into valuable carbon-based materials used in the production of food, plastics and other commodity chemicals. Jiao’s tandem CO₂ electrolysis produces acetate and ethylene. Acetate is a close relative of the more familiar acetic acid, or vinegar, which can be used as food for microbes used in biomanufacturing, and ethylene is a common component found in plastics and other polymers.

In a study published June 3 in Nature Chemical Engineering, Jiao demonstrated that his tandem CO₂ electrolyzer, which was specifically engineered for enhanced production of multi-carbon products, successfully scales up to produce a kilogram of chemicals per day at high concentration and purity. This represents a 1,000% increase in scale over previous demonstrations, offering a pathway to industrial feasibility.

A key achievement of Jiao’s system is not only enhanced production capability, but also the system’s resilience against industrial impurities, a critical factor in real-world applications.

Beyond lithium: Sodium-based batteries may power the future WashU researchers quantify solar absorption by black carbon in fire clouds In their most extreme form, wildfire clouds will inject smoke into the upper troposphere and lower stratosphere where it can linger and impact stratospheric temperatures and composition for several months. Some of the details of that impact have been investigated in new research from Washington University in St. Louis’ Center for Aerosol Science & Engineering (CASE).

The research was led by Rajan Chakrabarty, a professor in WashU’s McKelvey School of Engineering and his former student Payton Beeler, now a Linus Pauling distinguished postdoctoral fellow at Pacific Northwest National Laboratory. The study was published in Nature Communications.

The team made airborne measurements from within the upper portion of an active pyroCb thunderstorm in Washington state as part of the 2019 NOAA/NASA Fire Influence on Regional to Global Environments and Air Quality (FIREX-AQ) field campaign.

“We considered the full complexity and diversity of the measured black carbon size and morphology on a perparticle basis for accurate estimation of its solar absorption. What we discovered is that a pyroCb black carbon particle absorbs visible sunlight two times as much as a nascent black carbon particle emitted from smaller fires and urban sources,” he said.

The next step in this research is to take further measurements and do a more precise study of the black carbon behavior in the stratosphere.

Our increasing reliance on batteries has made considerations like their sustainability and ability to hold charge in a range of environments and the ability to reliably source materials needed to produce them urgent considerations.

Peng Bai, associate professor of energy, environmental & chemical engineering in the McKelvey School of Engineering at Washington University in St. Louis, received a two-year, $550,000 Partnerships for Innovation – Technology Translation award from the National Science Foundation to support his work on sodium-based batteries.

The award will allow Bai to expand his prior NSF-funded research to scale up and commercialize his sodium battery technology.

Bai’s sodium-based batteries deliberately move away from lithium and other rare elements used in traditional batteries. Sodium, a more abundant and easier to process material, promises lower production costs and alleviated supply chain vulnerabilities, fostering a more sustainable and economically efficient energy landscape. Sodiumbased batteries may also offer enhanced fast-charging capabilities and improved operation in cold environments, expanding their potential application in large-scale energy storage and portable electronics, including electric vehicles.

The project, “Development of high-performance long-life electrodes for sustainable sodium-based batteries,” has three main goals: ensuring consistency in larger production batches, developing greener manufacturing processes using water instead of toxic solvents, and optimizing production processes at a commercial scale.

These advancements would pave the way for sodium-based batteries to make their way into everyday technologies within five years, Bai says.

How to grow food without light The agriculture industry relies on photosynthesis to grow food to feed the world. However, the process is slow and requires a lot of resources that make the process inefficient to meet the world’s needs.

Feng Jiao, professor of energy, environmental & chemical engineering in the McKelvey School of Engineering at Washington University in St. Louis, along with Robert E. Jinkerson, assistant professor at the University of California, Riverside, propose to move to an electro-agriculture framework that combines carbon dioxide electrolysis with biological systems to boost the efficiency of food production.

Such a system could reduce agricultural land use in the United States by nearly 90% and allow food to be grown in urban areas and deserts without the need for light or pesticides. It also allows for fertilizer to be used more efficiently.

Jiao said the approach could reduce environmental impacts of food production, streamline supply chains and address the global food crisis. More about the electroagriculture system is found in research published Oct. 23 in Joule.
