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.”

UH lands $1.5M for endowed professorship and energy workforce initiative

funding the future

The University of Houston announced two major funding awards last month focused on energy transition initiatives and leadership.

Longtime UH supporters Peggy and Chris Seaver made a $1 million gift to the university to establish the Peggy and Chris Seaver Endowed Aspire Professorship, a faculty position “designed to strengthen UH Energy and expand the university’s leadership in addressing the most pressing global energy challenges,” according to a news release.

The new role is the third professorship appointed to UH Energy. The professorship can qualify for a dollar-for-dollar match through the Aspire Fund Challenge, a $50 million matching initiative launched by an anonymous donor.

“This gift will be key to cementing UH’s role as The Energy University,” Ramanan Krishnamoorti, vice president for energy and innovation at UH, said in the release. “By recruiting a highly respected faculty member with international experience, we are further elevating UH Energy’s global profile while deepening our impact here in the energy capital of the world.”

Also in January, the university shared that it would be joining the Urban Enrichment Institute (UEI) and the City of Houston to help train the next generation of energy workers, thanks to a $560,000 grant.

The Gulf Research Program of the National Academies of Sciences, Engineering and Medicine awarded the funding to the UEI, a nonprofit that supports at-risk youth. It will allow the UEI to work with UH’s Energy Transition Institute and the Houston Health Department to launch “Spark Energy Futures: Equipping Youth and Communities for the Energy Transition.”

The new initiative is designed for Houstonians ages 16-25 and will provide hands-on experience, four months of STEM-based training, and industry-aligned certifications without a four-year degree. Participants can also earn credentials and job placement support.

“Our energy systems are going through unprecedented changes to address the growing energy demands in the United States, Gulf Coast and Texas,” Debalina Sengupta, assistant vice president and Chief Operating Officer of ETI at UH, said in a news release.“To meet growing demands, the energy supply, transmission, distribution and markets associated with an ever-increasing energy mix needs a workforce skilled in multidimensional aspects of energy, as well as the flexibility to switch as needed to provide affordable, reliable and sustainable energy to our population.”

Keith Cornelius, executive director of UEI, added that he expects about 50 students to participate in the program’s inaugural year and that the program is looking to attract those interested in entering the energy workforce without a college degree.

“We’re looking to have tremendous success with the Energy Transition Institute,” Cornelius said. “This program is a testament to what can be done between a community-based organization, a major university and the city.”

The award was part of a $2.7 million grant that will fund four projects in the Gulf region, including two others in Texas. The Gulf Research Program Awards also granted $748,175 to launch the “Building the South Texas Energy Workforce” initiative in in Kingsville, Texas and $728,000 for “Texas Green Careers Academy: Activating a New Generation of Energy Professionals” in Austin.

Solar power and storage help save Texans millions on electric bills, CEO tells Senate

price stability

Solar power and battery storage are saving Texans hundreds of millions of dollars on their electric bills, the president and CEO of the Solar Energy Industries Association recently told a congressional committee.

Abigail Ross Hopper, the association’s president and CEO, said in testimony given to the U.S. Senate Environment and Public Works Committee that states like Texas that are adding significant capacity for solar power and battery storage are enjoying lower, more stable prices for electricity.

“Unsubsidized solar is now the cheapest source of electricity in history in much of the country,” Hopper said. “With no fuel costs, solar provides a hedge against natural gas price volatility that continues to cause electricity price spikes.”

“The only way to put downward pressure on prices is by bringing more power online, not less,” she added.

To illustrate the value of solar power and battery storage, Hopper compared two hot summer days in Texas—one in July 2022 and the other in July 2025.

Hopper explained that the Electric Reliability Council of Texas (ERCOT) had begun installing solar on its grid in 2022 but had very little battery storage. ERCOT manages 90 percent of the state’s electrical load.

When ERCOT grid conditions buckled under high demand on the highlighted day in 2022, the price of electricity spiked to nearly $1,500 per megawatt-hour, Hopper said.

“Three years later, the amount of solar had increased substantially and was complemented by energy storage,” she said.

On the specified day in 2025, under even greater demand than three years earlier, sizable amounts of solar power, battery storage and wind power kept ERCOT’s midday price of electricity low and stable—around $50 per megawatt-hour. That dollar amount represented a nearly 100 percent decrease compared with the highlighted day in 2022.

Solar and wind supplied nearly 40 percent of Texas’ power during the first nine months of 2025, according to the U.S. Energy Information Administration (EIA).

Despite the state’s expansion of solar power and battery storage capacity, residential electricity prices in ERCOT’s territory rose 30 percent from 2020 to 2025 and are expected to climb another 29 percent from 2025 to 2030, according to a forecast from the Texas Energy Poverty Research Institute.

The increase in electric bills is tied to factors such as:

Higher natural gas prices
Greater demand from AI data centers and cryptomining facilities
Extreme weather
Population growth
Development of new transmission and distribution lines

The strain on ERCOT’s grid is only getting worse. An EIA forecast predicts demand for ERCOT electricity will jump 9.6 percent in 2026, and ERCOT expects a 50 percent jump in demand by 2029.

Spring-based private equity firm acquires West Texas wind farm

power deal

Spring-based private equity firm Arroyo Investors has teamed up with ONCEnergy, a Portland, Oregon-based developer of clean energy projects, to buy a 60-megawatt wind farm southeast of Amarillo.

Skyline Renewables, which acquired the site, known as the Whirlwind Energy Center, in 2018, was the seller. The purchase price wasn’t disclosed.

Whirlwind Energy Center, located in Floyd County, West Texas, comprises 26 utility-scale wind turbines. The wind farm, built in 2007, supplies power to Austin Energy.

“The acquisition reflects our focus on value-driven investments with strong counterparties, a solid operating track record, and clear relevance to markets with growing capacity needs,” Brandon Wax, a partner at Arroyo, said in a press release. “Partnering with ONCEnergy allows us to leverage deep operational expertise while expanding our investment footprint in the market.”

Arroyo focuses on energy infrastructure investments in the Americas. Its portfolio includes Spring-based Seaside LNG, which produces liquefied natural gas and LNG transportation services.

Last year, Arroyo closed an investment fund with more than $1 billion in total equity commitments.

Since its launch in 2003, Arroyo has “remained committed to investing in high-quality assets, creating value and positioning assets for exit within our expected hold period,” founding partner Chuck Jordan said in 2022.
