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.”

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 trio lands on Time’s list of 10 most influential energy companies

making an impact

Three companies with headquarters in Houston made Time magazine’s new list of the 10 most influential energy companies.

The unranked list includes:

  • Houston-based oil and gas giant Chevron
  • Houston-based Fervo Energy, a geothermal power provider that just went public in a $1.9 billion IPO
  • Saudi Aramco, the world’s largest oil company, whose U.S. headquarters is in Houston

In naming Chevron to the list, Time cites the company’s standing as the only major American oil company operating in Venezuela. Time says Chevron wields “extraordinary power” over Venezuela’s massive oil reserves.

Despite pressure from the White House on U.S. oil and gas producers to ramp up investments in Venezuela, “Chevron has pumped the brakes, pledging to boost output gradually and not chase price fluctuations,” Time says.

“Chevron has been in Venezuela for over a century,” CEO Mike Wirth told shareholders in January. “We remain committed to leveraging our deep expertise and long-standing partnerships for the benefit of our shareholders and the people of Venezuela.”

Time points out that Fervo sits “at the front of the pack” in generation of geothermal energy. The Houston-based company uses fracking techniques borrowed from the oil and gas industry to create underground hot-rock reservoirs that heat water to generate electricity.

Fervo’s Cape Station in Utah is scheduled to start delivering power to the grid this year. At full capacity of 500 megawatts, it will be the first large-scale commercial geothermal plant in the U.S. Time says another site in Utah, Project Blanford, is Fervo’s hottest well yet, highlighting the potential for harnessing geothermal heat for at-scale clean energy.

“It’s hard to find something that can [deliver] reliable 24/7 energy, that’s carbon-free, and can be constructed in a timely manner,” Fervo CEO Tim Latimer said. “It’s energy without a lot of the compromises.”

Government-owned Saudi Aramco, which last year earned $104.7 billion in profit, not only is a dominant player in the Mideast oil and gas sector, but Time says it holds “global clout in politics and business” that reaches far beyond oilfields. For example, the company finances big projects spearheaded by Crown Prince Mohammad Bin Salman, who chairs Saudi Arabia’s sovereign wealth fund. These include initiatives in global sports, tourism, and AI.

Baker Hughes teams up with Oklahoma co. to advance geothermal development

geothermal partnership

In recent months, Houston-based energy corporation Baker Hughes has launched multiple partnerships to expand geothermal energy extraction across the United States. The latest, a deal with Oklahoma-based Helmerich & Payne Inc. (H&P), was announced Wednesday.

As part of the deal, H&P will provide a geothermal-capable land drilling rig, while Baker Hughes will contribute technology and expertise. The rig is expected to be deployed later this year, according to a news release.

“Geothermal energy plays a critical role in meeting growing power demand by providing clean, reliable baseload generation,” Amerino Gatti, executive vice president of oilfield services & equipment for Baker Hughes, said in the release. “This collaboration reflects a deliberate step to move its development in the U.S. from concept to reality. By working together, Baker Hughes and Helmerich & Payne are helping customers advance these critical energy projects with greater confidence and deliver reliable, sustainable power.”

Investment in the geothermal energy sector is currently exploding in the U.S., having grown by at least 1,000 percent just in the last seven years, according to a recent report by Rocky Mountain Institute.

On one hand, only about 1 percent of the American energy grid currently uses geothermal, but on the other, the U.S. holds roughly 25 percent of the world’s geothermal capacity. Harnessing that power becomes even more attractive as conflicts in Russia and Iran continue to hamstring energy markets from those countries and revitalize interest in renewable energy.

Baker Hughes has been at the forefront of the geothermal boom. This new deal with H&P combines H&P’s drilling platform technology with Baker Hughes’s subsurface and energy extraction support technologies.

“This agreement underscores Helmerich & Payne’s commitment to supporting emerging energy opportunities through our drilling technologies and operational expertise,” H&P President and CEO Trey Adams added in the release. “We are pleased to collaborate with Baker Hughes to support the advancement of geothermal development in the United States.”

The deal with H&P is just one of several recent ones Baker Hughes has closed. In March, they announced support for XGS’s geothermal extraction projects in New Mexico, which are being used to meet the increasing demands of data centers in the state. Last May, Fervo Energy selected Baker Hughes to supply equipment for its flagship geothermal project in Utah.
