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.”

Baker Hughes to provide equipment for massive low-carbon ammonia plant

coming soon

Houston-based energy technology company Baker Hughes has been tapped to supply equipment for what will be the world’s largest low-carbon ammonia plant.

French technology and engineering company Technip Energies will buy a steam turbine generator and compression equipment from Baker Hughes for Blue Point Number One, a $4 billion low-carbon ammonia plant being developed in Louisiana by a joint venture comprising CF Industries, JERA and Mitsui & Co. Technip was awarded a contract worth at least $1.1 billion to provide services for the Blue Point project.

CF, a producer of ammonia and nitrogen, owns a 40 percent stake in the joint venture, with JERA, Japan’s largest power generator, at 35 percent and Mitsui, a Japanese industrial conglomerate, at 25 percent.

The Blue Point Number One project, to be located at CF’s Blue Point ammonia production facility, will be capable of producing about 1.4 million metric tons of low-carbon ammonia per year and permanently storing up to 2.3 million metric tons of carbon dioxide.

Construction of the ammonia-making facility is expected to start in 2026, with production of low-carbon ammonia set to get underway in 2029.

“Ammonia, as a lower-carbon energy source, is poised to play a pivotal role in enabling and accelerating global sustainable energy development,” Alessandro Bresciani, senior vice president of energy equipment at Baker Hughes, said in a news release.

Earlier this year, British engineering and industrial gas company Linde signed a long-term contract to supply industrial gases for Blue Point Number One. Linde Engineering Americas is based in Houston.

Houston expert asks: Is the Texas grid ready for the future?

Guets Column

Texas has spent the past five years racing to strengthen its electric grid after Winter Storm Uri exposed just how vulnerable it was. Billions have gone into new transmission lines, grid hardening, and a surge of renewables and batteries. Those moves have made a difference, we haven’t seen another systemwide blackout like Uri, but the question now isn’t what’s been done, it’s whether Texas can keep up with what’s coming.

Massive data centers, electric vehicles, and industrial projects are driving electricity demand to unprecedented levels. NERC recently boosted its 10-year load forecast for Texas by more than 60%. McKinsey projects that U.S. electricity demand will rise roughly 40% by 2030 and double by 2050, with data centers alone accounting for as much as 11-12% of total U.S. electricity demand by 2030, up from about 4% today. Texas, already the top destination for new data centers, will feel that surge at a greater scale.

While the challenges ahead are massive and there will undoubtedly be bumps in the road (some probably big), we have an engaged Texas legislature, capable regulatory bodies, active non-profits, pragmatic industry groups, and the best energy minds in the world working together to make a market-based system work. I am optimistic Texas will find a way.

Why Texas Faces a Unique Grid Challenge

About 90% of Texas is served by a single, independent grid operated by ERCOT, rather than being connected to the two large interstate grids that cover the rest of the country. This structure allows ERCOT to avoid federal oversight of its market design, although it still must comply with FERC reliability standards. The trade-off is limited access to power from neighboring states during emergencies, leaving Texas to rely almost entirely on in-state generation and reserves when extreme weather hits.

ERCOT’s market design is also different. It’s an “energy-only” market, meaning generators are paid for electricity sold, not for keeping capacity available. While that lowers prices in normal times, it also makes it harder to finance backup, dispatchable generation like natural gas and batteries needed when the wind isn’t blowing or the sun isn’t shining.

The Risks Mounting

In Texas, solar and wind power supply a significant percentage of electricity to the grid. As Julie Cohn, a nonresident scholar at the Baker Institute, explains, these inverter‑based resources “connect through power electronics, which means they don’t provide the same physical signals to the grid that traditional generators do.” The Odessa incidents, where solar farms tripped offline during minor grid disturbances, showed how fragile parts of this evolving grid can be. “Fortunately, it didn’t result in customer outages, and it was a clear signal that Texas has the opportunity to lead in solving this challenge.”

Extreme weather adds more pressure while the grid is trying to adapt to a surge in use. CES research manager Miaomiao Rimmer notes: “Hurricane frequencies haven't increased, but infrastructure and population in their paths have expanded dramatically. The same hurricane that hit 70 years ago would cause far more damage today because there’s simply more in harm’s way.”

Medlock: “Texas has made significant strides in the last 5 years, but there’s more work to be done.”

Ken Medlock, Senior Director of the Center for Energy Studies at Rice University’s Baker Institute, argues that Texas’s problem isn’t a lack of solutions; it’s how quickly those solutions are implemented. He stresses that during the January 2024 cold snap, natural gas kept the grid stable, proving that “any system configuration with sufficient, dispatchable generation capacity would have kept the lights on.” Yet ERCOT load has exceeded dispatchable capacity with growing frequency since 2018, raising the stakes for future reliability.

Ken notes: “ERCOT has a substantial portfolio of options, including investment in dispatchable generation, storage near industrial users, transmission expansion, and siting generation closer to load centers. But allowing structural risks to reliability that can be avoided at a reasonable cost is unacceptable. Appropriate market design and sufficient regulatory oversight are critical.” He emphasizes that reliability must be explicitly priced into ERCOT’s market so backup resources can be built and maintained profitably. These resources, whether natural gas, nuclear, or batteries, cannot remain afterthoughts if Texas wants a stable grid.

Building a More Reliable Grid

For Texas to keep pace with rising demand and withstand severe weather, it must act decisively on multiple fronts, strengthening its grid while building for long-term growth.

Coordinated Planning: Align regulators, utilities, and market players to plan decades ahead, not just for next summer.
Balancing Clean and Reliable Power: Match renewable growth with flexible, dispatchable generation that can deliver power on demand.
Fixing Local Weak Spots: Harden distribution networks, where most outages occur, rather than focusing only on large-scale generation.
Market Reform and Technology Investment: Price reliability fairly and support R&D to make renewables strengthen, not destabilize, the grid.

In Conclusion

While Texas has undeniably improved its grid since Winter Storm Uri, surging electricity demand and intensifying weather mean the work is far from over. Unlike other states, ERCOT can’t rely on its neighbors for backup power, and its market structure makes new dispatchable resources harder to build. Decisive leadership, investment, and reforms will be needed to ensure Texas can keep the lights on.

It probably won’t be a smooth journey, but my sense is that Texas will solve these problems and do something spectacular. It will deliver more power with fewer emissions, faster than skeptics believe, and surprise us all.

Houston companies partner to advance industrial carbon capture tech

green team

Carbon Clean and Samsung E&A, both of which maintain their U.S. headquarters in Houston, have formed a partnership to accelerate the global use of industrial carbon capture systems.

Carbon Clean provides industrial carbon capture technology. Samsung E&A offers engineering, construction and procurement services. The companies say their partnership will speed up industrial decarbonization and make carbon capture more accessible for sectors that face challenges in decarbonizing their operations.

Carbon Clean says its fully modular columnless carbon capture unit, known as CycloneCC, is up to 50 percent smaller than traditional units and each "train" can capture up to 100,000 tonnes of CO2 per year.

“Our partnership with Samsung E&A marks a major milestone in scaling industrial carbon capture,” Aniruddha Sharma, chair and CEO of Carbon Clean, said in a news release.

Hong Namkoong, CEO of Samsung E&A, added that the partnership with Carbon Clean will accelerate the global rollout of carbon capture systems that “are efficient, reliable, and ready for the energy transition.”

Carbon Clean and Samsung E&A had previously worked together on carbon capture projects for Aramco, an oil and gas giant, and Modec, a supplier of floating production systems for offshore oil and gas facilities. Aramco’s Americas headquarters is also in Houston, as is Modec’s U.S. headquarters.
