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.”

University of Houston selected for DOE-backed energy storage innovation initiative

tapping in

The University of Houston was selected for a new energy storage initiative from the United States Department of Energy.

UH is part of the Energy Storage Research Alliance (ESRA), which is one of the two energy innovation hubs that the DOE is creating with $125 million. The DOE will provide up to $62.5 million in ESRA funding over a span of five years.

“To fuel innovation and cultivate a sustainable and equitable energy future, all universities, government entities, industry and community partners have to work together,” Ramanan Krishnamoorti, vice president for energy and innovation at UH, says in a news release. “No one person or entity can achieve all this by themselves. As the Energy University and a Carnegie-designated Tier One research university, located in Houston — a center of diverse talent and experience from across the energy industry — UH has a unique advantage of continuing to build on Houston’s global leadership and demonstrating solutions at scale.

The hubs will attempt to address battery challenges and encourage next-generation innovation, which include safety, high-energy density and long-duration batteries. The batteries will be made from inexpensive, abundant materials, per the release.

The work that will be done at ESRA and other hubs can optimize renewable energy usage, reduce emissions, enhance grid reliability, and assist in growing electric transportation, and other clean energy solutions.

ESRA will bring in 50 researchers from three national laboratories and 12 other universities, including UH. The deputy lead of the soft matter scientific thrust and the principal investigator for UH’s portion of the project will be Yan Yao. Yao is the Hugh Roy and Lillie Cranz Cullen Distinguished Professor at the UH Cullen College of Engineering and principal investigator at the Texas Center for Superconductivity.

ESRA will focus on three interconnected scientific thrusts and how they work together: liquids, soft matter, and condensed matter phases. Yao and his team have created next-generation batteries using low-cost organic materials. The team previously used quinones that can be synthesized from plants and food like soybeans to increase energy density, electrochemical stability and safety in the cathode. Yao’s team were the first to make solid-state sodium batteries by using multi-electron conformal organic cathodes. The cathodes had a demonstrated record of recharging stability of 500 charging cycles.

Robert A. Welch Assistant Professor of electrical and computer engineering at UH Pieremanuele Canepa, will serve as co-PI. Both will investigate phase transitions in multi-electron redox materials and conformable cathodes to enable solid-state batteries by “marrying Yao’s experimental lab work with Canepa’s expertise in computational material science,” according to the release.

Joe Powell, founding director of the UH Energy Transition Institute and a professor in the Department of Chemical and Biomolecular Engineering, will create a community benefit plan and develop an energy equity course.

“New energy infrastructure and systems can have benefits and burdens for communities,” Powell says in the release. “Understanding potential issues and partnering to develop best solutions is critical. We want everyone to be able to participate in the new energy economy and benefit from clean energy solutions.”

This project will be led by Argonne National Laboratory and co-led by Lawrence Berkeley National Laboratory and Pacific Northwest National Laboratory.

“This is a once in a lifetime opportunity,” adds Yao. “To collaborate with world-class experts to understand and develop new science and make discoveries that will lead to the next generation of batteries and energy storage concepts, and potentially game changing devices is exciting. It’s also a great opportunity for our students to learn from and work with top scientists in the country and be part of cutting-edge research.”

University of Houston pockets $5M in DOE funding for superconductivity projects

taking on tape

A program within the U.S. Department of Energy has deployed $10 million into three projects working on superconducting tape innovation. Two of these projects are based on research from the University of Houston.

The DOE's Advanced Research Projects Agency-Energy, or ARPA-E, issued the funding through its Novel Superconducting Technologies for Conductors Exploratory Topic. Superconductivity — found only in certain materials — is a focus point for the DOE because it allows for the conduction of direct electric current without resistance or energy loss.

The demand for HTS, or high-temperature superconducting, tapes has risen as the country moves toward net-zero energy, driving up the cost of the materials, which are manufactured outside of the U.S. Here's where the DOE wants to help.

“If we can improve superconductors and manufacture them here in the United States, we can ultimately speed up the energy transition through enabling cost savings, faster production, and improved capability,” ARPA-E Director Evelyn N. Wang says in the DOE press release. “The teams [selected] will all pursue ARPA-E’s mission to lower emissions, bolster national security, increase energy independence and improve energy efficiency through their critical research.”

Selva Research Group, a team from UH focused on scaling HTS tape production and led by Venkat Selvamanickam, M.D. Anderson Chair Professor of Mechanical Engineering and director of the Advanced Manufacturing Institute, received a $2 million grant.

“Even though our superconducting tape is three times better than today’s industry products, for us to be able to take it to full-scale commercialization, we need to produce it faster and at a lower cost while maintaining its high quality,” Selvamanickam says in a UH press release. “This funding is to address this challenge and it’s an important step forward towards commercialization of our technology.”

The other UH-based team is MetOx Technologies, which secured $3 million in funding to support the advancement of its proprietary manufacturing technology for its HTS wire. Co-founded in 1998 by Alex Ignatiev, UH professor emeritus of physics and a fellow of the National Academy of Inventors, who also serves as the company’s chief science officer, MetOx plans to open its new manufacturing facility by the end of the year.

“This ARPA-E funding not only allows MetOx to advance its HTS wire fabrication process that I developed at UH, but also signifies the DOE’s recognition that MetOx is important,” Ignatiev says in the release. “The cost-effective HTS product that MetOx is developing at scale is critical to the national and global application of HTS for the world’s energy needs.”

The ARPA-E funding emphasizes the need for advancement of HTS tape innovation, and UH-affiliated groups receiving two of the three grants indicates the school is a leader in the space — something UH Vice President for Energy and Innovation Ramanan Krishnamoorti is proud of.

“These awards recognize the relevance and quality of the research at UH and our commitment to making a meaningful impact by addressing society’s needs and challenges by transitioning innovations out of research labs and into the real world,” Krishnamoorti says in the release.

Houston geothermal startup bumps Series B to $180M with Nabors investment

fresh funding

Houston-based geothermal startup Quaise Energy has closed its Series B fundraising round at $180 million after inking a significant investment from another local energy leader.

Quaise, which is developing a 50-megawatt superhot geothermal plant in Oregon, announced a "first close" of the round last month at $134 million, led by San Francisco-based investment firm Prelude Ventures. The $46 million bump has been fueled by a $35 million investment from Houston-based Nabors Industries.

The funding will go toward the continued development of the company's superhot geothermal plant, Project Obsidian, as well as the commercialization of Quaise's millimeter-wave drilling system, according to a news release.

“We are unlocking the most powerful clean energy source on Earth, and the Series B signals deep conviction across a wide range of investors,” Carlos Araque, Quaise CEO and president, said in the release. “Nabors is an invaluable partner as we move millimeter wave drilling to full commercial operations at Project Obsidian and beyond.”

Nabors, a repeat investor in Quaise, has also entered into a strategic framework agreement with Quaise. Under the agreement, Quaise will have access to a dedicated Nabors land rig and drilling platform. Nabors will also provide expertise in reservoir modeling, well design and drilling strategy.

Last year, Quaise drilled to a depth of about 330 feet using its millimeter-wave technology at its field site in Central Texas. Canary Media previously reported that Quaise plans to drill to nearly 3,300 feet later this year and to deploy its millimeter-wave technology at its power plant in 2027. The plant is expected to deliver power to the Pacific Northwest in 2030.

Quaise and Nabors say the partnership will improve drilling performance, reduce costs and accelerate project timelines.

“Superhot geothermal has the potential to make clean energy ubiquitous. That is why we are excited about our close relationship with Quaise,” Anthony Petrello, president and CEO of Nabors, added in the release. “Quaise’s millimeter wave technology changes the equation entirely by reaching superhot rock at temperatures and depths that are inaccessible with conventional drilling, transforming geothermal from a location-dependent resource into a global energy solution. Combined with Nabors’ drilling expertise and infrastructure, we see a path to gigawatt-scale geothermal power that no other company can offer today.”

Quaise reports that with the latest funding, it has now raised $280 million. It raised $21 million in a Series A1 financing round in 2024 and a $52 million Series A in 2022.

The company announced in March that it was aiming to raise $200 million for Project Obsidian through $100 million in Series B funding, plus an additional $100 million from grants, debt and project-level finance.

Houston's KBR tapped to provide tech for first SAF plant in Kazakhstan

clean deals

Houston-based engineering and technology firm KBR Inc. has been tapped to provide technology for Kazakhstan's first sustainable aviation fuel (SAF) production plant.

KazMunayGas-Aero LLP (KMG-Aero), a subsidiary of Kazakhstan’s national oil and gas company KazMunayGas, and KazFoodProducts awarded the contract to KBR for the project. The plant will use the alcohol-to-jet (AtJ) process for producing aviation fuel and aims to support President Kassym-Jomart Kemeluly Tokayev’s goal of boosting Kazakhstan's profile as a global aviation player, according to a news release from KBR.

"We are honored to support KMG-Aero and KFP in advancing the national commitment to reduce greenhouse gas emissions, recognizing the pivotal role of aviation decarbonization in achieving these strategic objectives,” Jay Ibrahim, president of KBR Sustainable Technology Solutions, said in the release.

KBR will provide its PureSAF technology and engineering design for the project. Invented and developed by Swedish Biofuels AB, the PureSAF tech will be used to convert alcohol-based feedstocks into SAF. The PureSAF Technology can process multiple feedstocks—like bioethanol, syngas, carbon dioxide and hydrogen—and convert them to SAF, diesel and gasoline, according to KBR.

"KBR’s PureSAF is a feed-flexible, bankable technology that is designed to deliver high SAF yields and supports the project across the full lifecycle,” Ibrahim added in the release. “We look forward to closely collaborating and supporting the successful execution of this landmark SAF project.”

Earlier this summer, KBR was also chosen to provide technology for what’s expected to be Asia's first commercial-scale ethanol-to-jet (SAF) plant. The plant has a planned production capacity of up to 100,000 tons of SAF per year.

In addition to the SAF projects, KBR also announced this month that it has been selected by ORNX Green Hydrogen to provide proprietary ammonia technologies for a low-cost green ammonia project in Morocco.

The commitments come as KBR shifts its focus solely toward sustainability technology and services. The company is in the process of spinning off its Mission Technology Solutions business, which KBR recently announced will be named Trinzic. The remaining company, "New KBR," will serve the ammonia and syngas, chemical and petrochemicals, clean refining and circular economy markets.

Army to build nuclear microreactors at 5 U.S. bases, including Texas

Nuclear News

The U.S. Army announced Wednesday that it plans to add nuclear microreactors at five military bases from New York to Texas as a reliable source of energy independent of the commercial electric grid.

The announcement comes as the Trump administration pushes hard to develop the next generation of nuclear power, including billions in loans for large nuclear reactors to meet skyrocketing power demand from data centers and a pilot program to boost advanced reactor designs and projects for military and civilian use. No nuclear microreactors are supplying power to the commercial electric grid in the United States today.

Five companies selected by the Army will be awarded up to $2.2 billion in total over five years to own, construct and operate the microreactors, if they hit set milestones along the way for their performance. The Army expects that more than 20 nuclear microreactors will be built and operated.

Army and industry officials say microreactors offer a resilient power source for critical infrastructure at military installations in case the grid fails. Reactors can run for years without refueling.

Army Secretary Dan Driscoll said the awards will accelerate the military’s ability “to deliver safe, reliable baseload power directly to our installations. We are building the energy resilience necessary to project combat power globally, without relying on potentially vulnerable external grids,” he said.

The grants are part of the Army's “Janus Program” launched last year to deliver next-generation nuclear energy. Officials hope to push nuclear development forward so that advanced reactor designs move beyond experiments and prototypes to provide power for years to come. This will be the “spear tip,” said Jeff Waksman, principal deputy assistant secretary of the Army for installations, energy and environment.

“That is the transition that we are trying to effect here,” he said on a call with reporters Wednesday. “These are not meant to be Army-specific designs.”

Critics of building more nuclear reactors say they’re too expensive and riskier than other energy sources. The Army program is using the military's “deep pockets to provide a hidden subsidy” to nuclear companies that can't find private-sector customers for their hypothetical and uneconomical reactors, said Alan J. Kuperman, associate professor at the Lyndon B. Johnson School of Public Affairs at the University of Texas at Austin and coordinator of the Nuclear Proliferation Prevention Project.

The reactors will be licensed by the Army, rather than the U.S. Nuclear Regulatory Commission, which licenses commercial nuclear reactors. Kuperman said it's “a dangerous scam on many levels.”

Waksman said these reactors will shut down safely in case of a failure, they're small and the Army wouldn't add them to installations without being certain they are safe. He said the Army is working on a deal with the Energy Department to remove radioactive waste, and there won't be any long-term storage on these installations.

The Army is working to align its regulatory processes as much as possible, Waksman said, so that companies won’t need major changes to their designs to be later licensed by the NRC. Along with federal funding, the Army expects billions of dollars in private capital investment.

Army leads the military’s adoption of nuclear energy

President Donald Trump signed executive orders in May 2025 to speed up the development of nuclear power. The Army was tasked with ensuring that an advanced reactor would start operating at a domestic military installation no later than Sept. 30, 2028. The Janus program is named for the ancient Roman god of transitions.

Officials know that delivering nuclear power to a military base will be a challenge, so they picked five companies in case one or more fail, Waksman said. The selected companies are: Antares Nuclear at Fort Bragg in North Carolina; BWXT at Fort Campbell in Kentucky; General Atomics Electromagnetic Systems at Fort Hood in Texas; Radiant Industries at Fort Benning in Georgia; and Westinghouse Government Services at Fort Drum in New York.

Senate Minority Leader Chuck Schumer asked the Army to select Fort Drum. The critical missions Fort Drum supports require secure power generation, the New York Democrat said.

The military installations will remain connected to the grid. The reactors would not completely power them. Each reactor will provide between 1 megawatt to 20 megawatts of power, depending on the company's design. Major bases use as much power as a small city. Antares and Radiant are planning to deliver their reactors in three-packs, Waksman said.

The Army now uses diesel as a primary backup for critical infrastructure. But in a conflict, Waksman said, the Army may not be able to move fossil fuels easily wherever it needs them.

“That makes nuclear energy just a natural game changer,” he said. “It makes sense for the Army to take the lead here.”

A reactor at Fort Belvoir in Virginia, completed in 1957, was the first nuclear power reactor to provide electricity to a commercial power grid in the United States for an extended period, according to the U.S. Army Corps of Engineers.

Companies say this will accelerate US nuclear development

California-based Antares reached a crucial milestone under the U.S. pilot program that could allow it to produce electricity at Idaho National Lab next year. The company said the Army's announcement extends its momentum. Westinghouse Government Services said it’s proud to support the Army’s efforts to strengthen energy security and innovate.

Tori Shivanandan, president and chief operating officer of California-based Radiant, said the Army’s $750 million award “shows confidence in Radiant’s product and ability to manufacture, deploy and safely operate nuclear microreactors for the American military.” The Janus program “will build a stronger and more resilient America,” she said.

General Atomics Electromagnetic Systems said its reactor is designed to operate in remote, off-grid and extreme environments for 40 years. It said it will draw on more than 70 years of nuclear expertise to provide safe, dependable and independent power for the military.

Rex Geveden, BWXT's president and chief executive officer, said, “As we commence work on the Janus program, we are delivering the nation’s most credible and reliable path to deployable nuclear power.”
