At the 20th annual Energy Tech Venture Forum presented by Rice Alliance for technology and Entrepreneurship, 11 startups scored recognition from the event's investors who evaluated over 90 early-stage energy transition companies.

"The selection process was both exhilarating and challenging given the incredible ideas we've seen today," says Jason Sidhu, director of information services business engagement at TC Energy, who announced the top companies. "I want to extend my gratitude to every company that participate din this year's Energy Tech Venture Forum. Your commitment to solving energy problems and pursuing ambitions ideas is truly commendable." Read more.

Houston company breaks ground on 'world's largest' geothermal project with next-generation tech

Houston-based cleantech startup Fervo Energy has broken ground on what it's describing as the "world’s largest next-gen geothermal project."

Fervo says the a 400-milliwatt geothermal energy project in Cape Station, Utah, will start delivering carbon-free power to the grid in 2026, with full-scale production beginning in 2028.

The project, in southwest Utah, is about 240 miles southwest of Salt Lake City and about 240 miles northeast of Las Vegas. Cape Station is adjacent to the U.S. Department of Energy’s Frontier Observatory for Research in Geothermal Energy (FORGE) and near the Blundell geothermal power plant. Read more.

Houston faces critical inflection point amid energy transition, says expert

In 1914, Winston Churchill faced a difficult decision. Over two decades before his first term as Prime Minister during World War 2, he oversaw the entire Royal Navy as First Lord of the Admiralty. Shipbuilding technology was rapidly evolving in that era and one of the key questions was whether to use coal or oil as fuel for the large ships in the fleet. Coal was the more proven technology at that point and the British had a strong supply chain across the Empire. Oil was lighter and easier to operate, but the worldwide supply and infrastructure were still limited.

Ultimately Churchill was persuaded by Admiral Jacky Fisher and others to convert the entire fleet to oil. To resolve the supply chain issue, the British government bought a majority stake in Anglo-Persian Oil Company, which became BP. The Royal Navy was possibly the largest consumer of fuel worldwide at the time, so this decision had a major effect on the energy transition in that era. Within 30 years, steam engines were no longer used for transportation in most of the world.

In that same decade, Houston emerged as a leading energy hub in the United States: Humble Oil was founded, the Houston Ship Channel was dredged, and the Baytown Refinery was constructed. World War I in Europe, and the mass adoption of cars in the US spurred a major increase in demand for oil. Oil went on to dominate the global energy market, providing cheap and reliable transportation, industrial production, and materials. Houston grew and prospered along with it to become the 5th largest metro area in the country today. Read more.

Climate change-focused multimedia company Climate Now announced this week that it will partner with the city of Houston and Rice University to host a Carbon Management Community Summit this fall.

The summit, sponsored by the U.S. Department of Energy, will be held at Rice University Bioscience Research Collaborative on November 16 and 17, and will feature interactive workshops and breakout learning sessions, as well as presentations and discussions from excerpts in the field. It will also be broadcasted virtually for those who cannot attend the event in person. Read more.

Texas company secures $200M for solar project near Houston

An Austin-based company has scored $200 million in financing for a solar energy project it’s building in Liberty County.

Recurrent Energy’s 134-megawatt Liberty Solar project, about 50 miles northeast of Houston, is scheduled to start operating in 2024. The facility will occupy more than 1,000 acres of former farmland about six miles south of Dayton.

Last year, Recurrent Energy indicated the project represented an investment of $155 million, according to paperwork filed with the Texas Comptroller of Public Accounts. Read more.

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.”
