Rice University researchers have teamed up with South Korean scientists to develop the first eco-friendly technology that captures and destroys toxic “forever chemicals,” or PFAS, in water.

PFAS have been linked to immune system disruption, certain cancers, liver damage and reproductive disorders. They can be found in water, soil and air, as well as in products like Teflon pans, waterproof clothing and food packaging. They do not degrade easily and are difficult to remove.

Thus far, PFAS cleanup methods have relied on adsorption, in which molecules cling to materials like activated carbon or ion-exchange resins. But these methods tend to have limited capacity, low efficiency, slow performance and can create additional waste.

The Rice-led study, published in the journal Advanced Materials, centered on a layered double hydroxide (LDH) material made from copper and aluminum that could rapidly capture PFAS and be used to destroy the chemicals.

The study was led by Rice professor Youngkun Chung, a postdoctoral fellow under the mentorship of Michael S. Wong. It was conducted in collaboration with Seoktae Kang, professor at the Korea Advanced Institute of Science and Technology, and Keon-Ham Kim, professor at Pukyung National University, who first discovered the LDH material.

The team evaluated the LDH material in river water, tap water and wastewater. And, according to Rice, that material’s unique copper-aluminum layers and charge imbalances created an ideal binding environment to capture PFAS molecules.

“To my astonishment, this LDH compound captured PFAS more than 1,000 times better than other materials,” Chung, lead author of the study and now a fellow at Rice’s WaTER (Water Technologies, Entrepreneurship and Research) Institute and Sustainability Institute, said in a news release. “It also worked incredibly fast, removing large amounts of PFAS within minutes, about 100 times faster than commercial carbon filters.”

Next, Chung, along with Rice professors Pedro Alvarez and James Tour, worked to develop an eco-friendly, sustainable method of thermally decomposing the PFAS captured on the LDH material. They heated saturated material with calcium carbonate, which eliminated more than half of the trapped PFAS without releasing toxic by-products.

The team believes the study’s results could potentially have large-scale applications in industrial cleanups and municipal water treatments.

“We are excited by the potential of this one-of-a-kind LDH-based technology to transform how PFAS-contaminated water sources are treated in the near future,” Wong added in the news release. “It’s the result of an extraordinary international collaboration and the creativity of young researchers.”

Houston researchers harness dialysis for new wastewater treatment process

waste not

By employing medical field technology dialysis, researchers at Rice University and the Guangdong University of Technology in China uncovered a new way to treat high-salinity organic wastewater.

In the medical field, dialysis uses a machine called a dialyzer to filter waste and excess fluid from the blood. In a study published in Nature Water, Rice’s team found that mimicking dialysis can separate salts from organic substances with minimal dilution of the wastewater, addressing some of the limitations of previous methods.

The researchers say this has the potential to lower costs, recover valuable resources across a range of industrial sectors and reduce environmental impacts.

“Traditional methods often demand a lot of energy and require repeated dilutions,” Yuanmiaoliang “Selina” Chen, a co-first author and postdoctoral associate in Elimelech’s lab at Rice, said in a news release. “Dialysis eliminates many of these pain points, reducing water consumption and operational overheads.”

Various industries generate high-salinity organic wastewater, including petrochemical, pharmaceutical and textile manufacturing. The wastewater’s high salt and organic content can present challenges for existing treatment processes. Biological and advanced oxidation treatments become less effective with higher salinity levels. Thermal methods are considered “energy intensive” and susceptible to corrosion.

Ultimately, the researchers found that dialysis effectively removed salt from water without requiring large amounts of fresh water. This process allows salts to move into the dialysate stream while keeping most organic compounds in the original solution. Because dialysis relies on diffusion instead of pressure, salts and organics cross the membrane at different speeds, making the separation method more efficient.

“Dialysis was astonishingly effective in separating the salts from the organics in our trials,” Menachem Elimelech, a corresponding author on the study and professor of civil and environmental engineering and chemical and biomolecular engineering at Rice, said in a news release. “It’s an exciting discovery with the potential to redefine how we handle some of our most intractable wastewater challenges.”

Energy expert: Houston welcomed the world — can Texas power what's next?

guest column

For a few weeks this summer, Houston welcomed the world.

The FIFA World Cup 2026 showcased our city's ability to host one of the largest international events on the planet. Millions watched from around the globe while hundreds of thousands of visitors experienced firsthand what Houston has become: a world-class destination for business, culture and global events.

But once the final match is played and the visitors return home, a more important question remains: Can Texas build the energy infrastructure needed to power what comes next?

The World Cup wasn't the finish line. It was a glimpse into the future.

That future is being shaped not only by population growth, but also by artificial intelligence, hyperscale data centers, advanced manufacturing, electrification, LNG expansion and continued industrial investment. Together, these forces are creating an unprecedented demand for electricity and placing new expectations on the infrastructure that supports it.

Energy Has Become Economic Infrastructure

For decades, economic development centered around highways, ports, airports and workforce.

Today, another asset has moved to the top of that list: energy infrastructure.

Reliable electricity is no longer simply a utility service. It has become a competitive advantage.

Companies evaluating where to build the next AI campus, manufacturing facility or industrial complex are increasingly asking different questions. How quickly can power be delivered? Is there enough transmission capacity? Can substations support future expansion? Is water infrastructure available? What is the long-term reliability of the local grid?

These questions are becoming just as important as tax incentives and available real estate.

Recent comments from Governor Greg Abbott that future AI developments should provide their own power generation and water illustrate just how dramatically the conversation has evolved. The challenge is no longer limited to meeting today's demand. It is preparing for a future where entirely new industries require unprecedented amounts of electricity while ensuring existing homes and businesses continue to receive reliable, affordable service.

The Next Energy Race Has Already Begun

Texas remains the nation's energy leader, producing more electricity than any other state while continuing to expand natural gas, wind, solar and emerging technologies.

But leadership in the next decade will be measured differently.

Success will depend on how quickly we can expand transmission infrastructure, modernize distribution systems, accelerate interconnection, strengthen grid resilience and support new generation where economic growth is occurring.

The conversation has shifted from producing more electricity to delivering it smarter.

That requires planning years before demand arrives.

Houston Is the Proving Ground

Houston sits at the center of this transformation.

Already recognized as the Energy Capital of the World, the region continues attracting major employers, global headquarters, industrial expansion and technology investment. The Port of Houston continues to grow. Advanced manufacturing is expanding. AI companies are evaluating Texas alongside other national markets.

Every one of these investments depends on reliable infrastructure.

While the World Cup demonstrated Houston's ability to manage a temporary surge of visitors, the more significant challenge lies ahead. Permanent economic growth creates sustained electricity demand that cannot be addressed with temporary solutions.

Meeting that demand will require coordinated investment across generation, transmission, distribution, storage and increasingly, digital technologies capable of forecasting and managing electricity in real time.

Smarter Infrastructure for a Smarter Grid

The future electric grid will look very different from the one that built modern Texas.

Artificial intelligence, predictive analytics, advanced sensors and distributed energy resources will allow operators to anticipate demand, identify equipment failures before they occur and optimize energy delivery across increasingly complex networks.

Infrastructure is no longer simply about building more. It is about building smarter.

At the same time, resilience must remain central to every investment. Texans understand better than most that hurricanes, flooding, winter storms and prolonged heat waves are no longer rare events. Modern infrastructure must not only support growth but also withstand increasingly volatile weather.

Building Beyond the Headlines

The World Cup generated headlines because of what happened on the field.

Its lasting legacy may be what it revealed about the city beyond the stadium.

Houston demonstrated that it can host the world. The next challenge is ensuring it can continue to power one of the fastest-growing economies in North America.

That will require continued investment, thoughtful policy and long-term planning that recognizes energy infrastructure as essential economic infrastructure.

Texas has spent decades leading the world in energy production.

The next opportunity is even greater.

To become the global leader in how energy systems are planned, built and operated for a future defined by artificial intelligence, industrial growth and rapidly evolving consumer demand.

Because the cities that lead tomorrow won't simply generate the most energy.

They'll be the ones best prepared to deliver it where opportunity is growing.

“As demands on the energy grid continue to grow, Dresser plays a critical role as a trusted partner to utilities managing essential infrastructure. The company’s products are foundational to the safe and reliable operation of gas and water networks, and its reputation for quality has helped build longstanding customer relationships,” David Foley, global head of Blackstone Energy Transition Partners, and JP Munfa, senior managing director, said in the release.

Blackstone Energy Transition Partners has invested more than $28 billion across the energy transition sector. New York-based Blackstone closed Blackstone Energy Transition Partners Fund IV at $5.6 billion in February 2025. Blackstone Energy Transition Partners Fund III closed in 2020 for $4.4 million, according to Pitchbook.

Other notable energy transition investments from Blackstone funds include Salt Lake City-based Energy Exemplar, French electronics manufacturing company Sediver, Plano-based Westwood Professional Services and others.

Two years ago, Dresser secured a $335 million credit facility from funds managed by asset manager Blue Owl Capital. At the time, Dresser said the money would go toward capital expenses, acquisitions and corporate needs.

This is the second notable investment Blackstone has made in a Houston-based energy company in recent months. In May, Blackstone and energy heavyweight Halliburton made a $1 billion equity investment in Houston power generation startup VoltaGrid, which provides behind-the-meter mobile power generation equipment for data centers, microgrids and industrial customers.
