The “missing link” in critical minerals may have been in our junk drawers all along, according to new research from the University of Houston.

Jian Shi, an associate professor in the UH Cullen College of Engineering, and his team have unveiled a new supply chain model that aims to make e-waste economically viable and could help make large-scale recycling possible.

Shi, along with professor Kailai Wang and graduate researcher Chuyue Wang, published the work in a recent issue of Nature. Their study outlines how gold, lithium and cobalt from discarded electronics can be kept circulating in the U.S. through the process of “urban mining.” It was supported by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) through the Vehicle Technologies Office.

The team’s research found that e-waste is the fastest-growing solid waste stream in the world. When waste from smartphones or tablets is left unmanaged, the devices can leak hazardous waste and pose significant fire risks due to aging batteries. Additionally, when they are shipped off to foreign landfills, the U.S. loses the potential to recycle or reuse the critical minerals left inside.

“A lot of people have iPads or old iPhones sitting in their drawers right now, and that’s a waste of a critical resource,” Shi said in a news release. “Urban mining allows us to extract the same high-value materials found in traditional mines without the environmental destruction. More importantly, it helps secure our domestic supply chain for the technologies of tomorrow.”

According to UH, recycling e-waste has not succeeded in the U.S. due to a fragmented recycling system, in which manufacturers, collectors and recyclers operate separately, driving up costs.

The UH team's research looks to change that.

In the study, the researchers modeled streamlined recycling efforts by mapping the interactions between manufacturers and independent recycling markets. Their dual-channel closed-loop supply chain (CLSC) model identified how these players can transition from competitors to partners, which can distribute profits more equitably and make recycling efforts more financially attractive.

According to UH, the research has particular significance due to the growing demand for electronic vehicles and their batteries.

“We can improve the performance of the entire recycling ecosystem and make the profit distribution more balanced,” Wang said in the release. “This ensures that the materials we need for EVs and advanced electronics stay right here in the U.S.”

“By making recycling work at scale, we aren’t just cleaning up waste,” Shi added. “We’re building a foundation that benefits both our national security and our economy.”

Experts from the University of Houston are teaming up with the city on key sustainability efforts.

University of Houston collaborates with county on future-facing sustainability efforts

dream team

Researchers at the University of Houston are partnering with the Harris County Office of County Administration’s Sustainability Office, the Harris County Energy Management Team, and other county staff in an effort to develop a comprehensive baseline of energy use and energy-use intensity that will aim to reduce energy costs and emissions in county facilities.

Once fully established, the team will work on tracking progress and evaluating the effectiveness of energy-saving measures over time. They will begin to build the foundation for future programs aimed at maximizing savings, reducing energy consumption, and increasing the use of renewable energy sources in county operations.

Harris County energy managers, Glen Rhoden and Yas Ahmadi, will work with UH professionals, including:

  • Jian Shi, UH Cullen College of Engineering associate professor of engineering technology and electrical and computer engineering
  • Zhu Han, Moores professor of electrical and computer engineering
  • Xidan "Delia" Zhang, UH research intern

The group began collaborating a year ago, and analyzed energy consumption data from county facilities.They were able to successfully identify key summertime energy-saving opportunities and completed retro-commissioning of four county buildings. Those efforts saved over $230,000 annually in electricity costs.

“This project is a prime example of how impactful research at UH can be when applied to real-world challenges, delivering tangible benefits to both the environment and the communities we serve,” Shi says in a news release.

The team will plan to do additional building projects, which includes the development of solar energy and heat pump initiatives, building automation system upgrades, and LED lighting installations. The goal is to reduce electricity usage by at least 5 percent per year for county facilities by 2030 and cut greenhouse gas emissions by 50 percent over the next 5 years for county buildings.

“Addressing climate change and the energy transition requires a collaborative effort that is not only data-driven and action-oriented but also human-centric,” Shi adds. “It’s about more than just technology—it’s about improving the quality of life for Texans.”

Houston researcher scores $500,000 award to continue on work on energy transition

zeroing in on zero emissions

A University of Houston professor and researcher is laser focused on his work within the energy transition, and National Science Foundation has taken note, awarding him over half a million dollars in funding.

Jian Shi, an assistant professor within the Cullen College of Engineering, recently received the NSF's CAREER award, which will dole out $500,861 in funding through February 2029.

The award was granted for his research, entitled “A Unified Zero-Carbon-Driven Design Framework for Accelerating Power Grid Deep Decarbonization.”

“One of the most major challenges inherent in energy transition is the cost. While reducing carbon emissions serves the best interest of society in the long run, the short-term financial burdens also need to be carefully evaluated to ensure that we have a safe, affordable, reliable and just transition for all,” Shi says in a UH news release. “This challenge has inspired me to work on the innovative framework of “ZERO-Accelerator.”

Shi's ZERO-Accelerator is focused on taking standard carbon-driven tools and integrating them into current power grid operational practices. Shi is the director and founder of SOAR, or the Smart and ZerO-Carbon Energy Analytics and Research Lab.

“It synthesizes interactions from multiple key stakeholders involved in the electricity ecosystem,” says Shi. “The framework considers how to manage carbon allowance allocation and trading for electricity producers, how to maintain a 24/7 zero-carbon power grid for power grid operators and how to enable consumers to understand their carbon footprint and participate in the zero-carbon grid operation.”

In his CAREER proposal, Shi explains that he is also contributing to training the future energy workforce. He adds that he shares this award with his colleagues.

“I believe no accomplishment is truly individual,” he says. “Rather, it is a collective triumph achieved through collaboration, support and shared dedication. As I reflect on the milestones I've reached, I am compelled to express my deepest gratitude to my esteemed colleagues whose unwavering commitment has been instrumental in not just my collective success, but our collective success as well."

Last summer, Shi mentored a UH team in the inaugural American-Made Carbon Management Collegiate Competition, hosted by the U.S. Department of Energy's Office of Fossil Energy and Carbon Management. The team, GreenHouston, took third place in the competition, securing a $5,000 cash prize.

Houston scientists' breakthrough moves superconductivity closer to real-world use

energy breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”

Energy expert: What record heat and extended summers mean for Texans

guest column

Earth’s third-warmest year on record occurred in 2025, reinforcing a decades-long pattern of rising global temperatures. This warming trend is increasingly reflected in regional weather patterns across the United States, particularly in Texas, where hotter summers, prolonged droughts, and heavier rainfall events are becoming more common.

A 2024 report from Texas A&M University highlights how these shifts are already reshaping weather conditions across the Lone Star State. The assessment analyzes climate and weather data from 1900 through 2023 and projects likely trends through 2036.

Its findings suggest that extreme weather in Texas is not only increasing but also becoming more hazardous for communities, infrastructure, and the economy.

A Rise in Extreme Heat
One of the most dramatic changes is the increasing frequency of extreme heat events. Summer temperatures in Texas have climbed back to levels not seen since the early 20th century, and projections suggest they will exceed those historic highs within the next decade.

Triple-digit temperatures are becoming far more common. In the 1970s and 1980s, most parts of Texas experienced relatively few days above 100°F in a typical year. By 2036, those days are expected to occur about four times as often, especially across North, Central, and West Texas.

Houston reflects that broader trend. Five of the 10 years with the most 100-degree days on record in the city have occurred since 2000, according to records dating back to the late 1880s.

The summer of 2023 was Houston’s hottest on record, surpassing even the historic heat of 2011. While short-term cold snaps still occur, climate data suggests extreme summer heat will become more frequent in the years ahead.

Heat waves are also starting earlier in the year and lasting longer. As of 2024, the average length of heat-wave season in the United States has increased by 46 days since the 1960s. Their frequency has also increased steadily, rising from an average of two heat waves per year in the 1960s to about six per year in the 2010s and 2020s.

Energy Grid Strain
Heat waves occurring earlier in the year and more intensely place increasing pressure on the state’s electricity system. When temperatures spike early in the summer, households and businesses simultaneously increase air-conditioning use, pushing electricity demand close to record levels.

In recent summers, record-breaking electricity demand has repeatedly tested grid capacity. Energy experts warn that if heat extremes continue to intensify, maintaining grid reliability will require expanded generation capacity, improved energy efficiency, and greater integration of renewable energy and battery storage. Fortunately, Texas has already made strides in these areas of concern.

Texas continues to lead the nation in clean energy adoption and grid modernization, particularly in wind and solar power. With more than 40,000 megawatts (MW) of wind capacity, the state ranks first in the country in wind-powered electricity generation, supplying up to 35% when blowing and as low as 0%. Much of this growth was driven by the state’s Renewable Portfolio Standard (RPS), which requires utility companies to develop renewable energy in proportion to their market share. The policy originally set a goal of generating 10,000 MW of renewable capacity by 2025, but Texas surpassed this target years ahead of schedule due to rapid investment and expansion.

Solar energy is also growing quickly. Texas has officially overtaken California as the country’s. leader in utility-scale solar, according to recently released data from the U.S. Energy Information Administration. With over 37 GW of capacity, Texas now leads in new solar installations, supported by large-scale solar farm development and favorable policies that continue to diversify the state’s energy mix.

To build a more resilient and cost-effective power system, Texas is working to integrate wind and solar generation while strengthening grid reliability. Efforts include regulatory reforms, mandates for improved power infrastructure, and the deployment of renewable energy storage solutions. A recent report from the Solar Energy Industries Association indicates that Texas is on track to surpass California this year as the nation’s leader in energy storage capacity, driven largely by the rapid growth of battery storage facilities across the state. Alongside renewable expansion, the state also added 3,410 MW of natural gas–fueled power in 2024 to support growing electricity demand.

Economic Consequences
Extreme heat also has measurable economic impacts. For every 1-degree increase in the average summer temperature, Texas’ annual nominal GDP growth rate slows by about 0.4 percentage points. Because Texas already experiences hotter summers than most of the country, rising temperatures affect the state’s economic growth about twice as much as they do in the rest of the United States. Additional warming compounds the strain on productivity, infrastructure, and energy costs.

Some industries are more sensitive to heat than others. Construction, agriculture, manufacturing, and outdoor services often experience productivity losses during prolonged heat waves.

The effects were already visible during the record-breaking summer of 2023, when cities such as Houston, Dallas, and El Paso experienced prolonged stretches of triple-digit temperatures. Surveys conducted by the Federal Reserve Bank of Dallas found that roughly one-quarter of businesses responding to the Texas Business Outlook Surveys reported reduced revenue or production because of the heat.

The hardest-hit sector was leisure and hospitality, where outdoor activities and tourism often decline during extreme temperatures. However, businesses across manufacturing, retail, and services also reported disruptions.

Environmental and Infrastructure Stress
In addition to heat, there are growing risks related to drought, wildfire conditions, and urban flooding.

Extended heat waves tend to worsen drought conditions by increasing evaporation and reducing soil moisture. Lower water levels in lakes and reservoirs can lead to water restrictions for cities and agricultural producers, especially in regions that rely heavily on surface water supplies.

Dry conditions also increase the likelihood of wildfires, particularly across West Texas and the Hill Country. Strong winds, dry vegetation, and extreme heat can quickly turn small fires into fast-moving blazes that threaten homes, infrastructure, and ecosystems.

At the same time, Texas is experiencing an increase in severe rainfall events, which can overwhelm drainage systems in rapidly growing urban areas. Cities with large amounts of pavement and development are especially vulnerable to flash flooding when heavy rain falls in short bursts.

Along the Gulf Coast, rising sea levels are adding another layer of risk. Communities near Galveston Bay and other low-lying coastal areas face increasing threats from storm surge and high-tide flooding.

Preparing for a Hotter Future
Climate experts emphasize that over the next decade, Texans are likely to face more frequent heat waves, higher energy demand, and greater environmental stress.

Adapting to these changes will require a range of responses, including strengthening infrastructure, expanding water management strategies, improving urban planning, and enhancing emergency preparedness for extreme heat and flooding.

While the challenges are significant, understanding these trends now gives policymakers, businesses, and communities time to prepare. As the state’s population and economy continue to grow, resilience to extreme weather is an increasingly important priority for Texas in the years ahead.

Woodside Energy names new CEO with sustainability focus

new leader

Woodside Energy has officially named Elizabeth Westcott as its new managing director and CEO.

Westcott has served as the company's acting CEO since Meg O'Neill stepped down in December 2025. Woodside is headquartered in Australia with its global operations based in Houston.

Before joining Woodside as executive vice president of Australian Operations in 2023, Westcott served as COO at EnergyAustralia. She has also held leadership roles at ExxonMobil and Adriatic LNG.

At Woodside, she has overseen the $12.5 Scarborough Energy Project, which the company says is expected to be one of the lowest-carbon-intensity sources of LNG, as well as other major projects and initiatives.

“My focus as CEO is on sustainable value creation for Woodside shareholders, operational excellence and disciplined execution of our growth projects," Westcott said in a news release. “I look forward to working closely with the Board and Woodside’s strong leadership team to continue building a leading global energy company that delivers long-term value for shareholders, underpinned by a consistent focus on sustainability and high performance.”

Woodside Chair Richard Goyder added that Westcott was the top choice for the role.

“Liz’s proven track record of outstanding strategic leadership and disciplined delivery distinguished her as the Board’s top candidate for this role," Goyder said. “Liz’s extensive industry experience and strategic vision will be invaluable in leading Woodside at this significant moment in its history.”

Earlier this month, Westcott spoke on how sustainability is a priority for Woodside.

"Put simply, sustainable business is good business ... Because strong sustainability performance is not only the right thing to do. It also drives long-term value by helping to de-risk our business, secure future opportunities and support a compelling value proposition for investors," she said in her 2026 sustainability briefing.

Westcott called attention to the company's Beaumont New Ammonia project. The company acquired the Texas-based clean ammonia project in 204 for $2.35 billion. Production of lower‑carbon ammonia was initially expected sometime this year, but Westcott shared that delivery has been pushed back due to construction delays.
