A team of researchers at the University of Houston has made two breakthroughs in addressing climate change and potentially reducing the cost of capturing harmful emissions from power plants.

Led by Professor Mim Rahimi at UH’s Cullen College of Engineering, the team released two significant publications that made significant strides relating to carbon capture processes. The first, published in Nature Communications, introduced a membraneless electrochemical process that cuts energy requirements and costs for amine-based carbon dioxide capture during the acid gas sweetening process. Another, featured on the cover of ES&T Engineering, demonstrated a vanadium redox flow system capable of both capturing carbon and storing renewable energy.

“These publications reflect our group’s commitment to fundamental electrochemical innovation and real-world applicability,” Rahimi said in a news release. “From membraneless systems to scalable flow systems, we’re charting pathways to decarbonize hard-to-abate sectors and support the transition to a low-carbon economy.”

According to the researchers, the “A Membraneless Electrochemically Mediated Amine Regeneration for Carbon Capture” research paper marked the beginning of the team’s first focus. The research examined the replacement of costly ion-exchange membranes with gas diffusion electrodes. They found that the membranes were the most expensive part of the system, and they were also a major cause of performance issues and high maintenance costs.

The researchers achieved more than 90 percent CO2 removal (nearly 50 percent more than traditional approaches) by engineering the gas diffusion electrodes. According to PhD student and co-author of the paper Ahmad Hassan, the capture costs approximately $70 per metric ton of CO2, which is competitive with other innovative scrubbing techniques.

“By removing the membrane and the associated hardware, we’ve streamlined the EMAR workflow and dramatically cut energy use,” Hassan said in the news release. “This opens the door to retrofitting existing industrial exhaust systems with a compact, low-cost carbon capture module.”

The second breakthrough, published by PhD student Mohsen Afshari, displayed a reversible flow battery architecture that absorbs CO2 during charging and releases it upon discharge. The results suggested that the technology could potentially provide carbon removal and grid balancing when used with intermittent renewables, such as solar or wind power.

“Integrating carbon capture directly into a redox flow battery lets us tackle two challenges in one device,” Afshari said in the release. “Our front-cover feature highlights its potential to smooth out renewable generation while sequestering CO2.”

New report shows that Houston and Texas are making strides in wind energy

More power to us

With over 4,600 energy-related businesses employing more than 237,000 people, Houston has earned recognition as the "Energy Capital of the World." But when people think of Houston's energy sector, oil and gas almost automatically come to mind, given that about one-third of the publicly traded oil and gas companies in the U.S. are based in the Houston area.

Yet wind energy is making inroads in Houston. Susan Davenport, senior vice president for economic development at the Greater Houston Partnership, says more than 30 companies in the Houston area operate in the wind energy sector.

"Houston is actively working to grow this sector, so we hope people will seriously think of Houston when they think of renewables in this new era of energy," Davenport says at an April 9 news conference in Houston where the American Wind Energy Association released its 2018 state-of-the-industry report.

That's not to say, though, that Houston is ready to cede its dominance in the oil and gas sector.

"Houston has long held the title of 'Energy Capital of the World,' and we fully intend to maintain that status," Davenport says. "As global energy forecasts continue to show an ever-increasing need for energy, we know oil and gas will be critical for years to come. But at the same time, as that energy mix gets larger, we know an increasing share of energy will come from renewables. And we're already capturing a sizable share [of that market]."

That sizable market share includes venture capital. Of the $5.2 billion in venture capital reeled in by Houston businesses from 2015 to 2017, renewable energy accounted for more than 35 percent, according to the Greater Houston Partnership.

Davenport said Houston is "uniquely suited" to support companies involved in wind energy and other types of renewable energy, thanks to its deep pool of energy-oriented talent.

The American Wind Energy Association's annual report for 2018 shows the wind energy sector employs between 25,000 and 26,000 people in Houston and elsewhere in Texas, up from 24,000 to 25,000 in 2017, with the total investment in Texas wind energy projects sitting at a whopping $46.5 billion. More than one-fifth of wind energy jobs in the U.S. are located in Texas.

In employment, investment, and several other categories, Texas rules as the undisputed leader of the U.S. wind energy industry.

"The success story in Texas continues," says Susan Williams Sloan, the Austin-based vice president of state policy for the American Wind Energy Association.

The report indicates the Lone Star State is home to roughly one-fourth of all U.S. wind power production. If Texas were a country, the wind energy group says, it would rank fifth in the world for wind power capacity, with nearly 25,000 megawatts installed. And with nearly 7,000 megawatts of wind energy projects under construction or development at the end of 2018, Texas is adding more wind energy capacity than what all but two other states actually have installed.

At of the end of 2018, nearly 13,400 wind turbines dotted the state's landscape, mostly in West Texas.

It's not just utilities that are fueling the growth of wind power in Texas. The association calls Texas the "nexus" for non-utility demand for wind power.

Today, 38 non-utility companies have bought or are planning to buy 4,900 megawatts of wind energy in Texas, including Shell Energy, AT&T, Budweiser, ExxonMobil, and Walmart, according to the association.

"Texas continues to lead the nation, with hard work and ingenuity, in harnessing this great American renewable energy resource, literally out of thin air," says Tom Kiernan, CEO of the Washington, D.C.-based American Wind Energy Association. "Texas has a long and storied history of energy production and as [our] report demonstrates, wind is an important part of the state's energy success story. In many ways, the Texas wind story is the story of American wind power."

The association released its 2018 report in advance of WINDPOWER, the wind energy industry's biggest conference, which is set for May 20 to 23 at Houston's George R. Brown Convention Center. More than 8,000 people are expected to attend.

Houston lands $14M in latest CPRIT grants to advance cancer, lab-on-chip research

cancer funding

Thanks to a $4 million grant from the Cancer Prevention and Research Institute of Texas, the University of Houston has recruited a top-tier researcher developing AI-powered lab-on-a-chip technology for early cancer detection.

Tianhong Cui, a professor of mechanical engineering at the University of Minnesota Twin Cities and an adjunct professor of physiology and biomedical engineering at the Mayo Clinic, specializes in microelectromechanical systems and advanced manufacturing at microscale and nanoscale levels. In addition to lab-on-a-chip systems, Cui focuses on biosensors and water sensors.

Lab-on-a-chip devices deliver big results in a tiny package

The CPRIT grant supports Cui’s development of a microscale lab-on-a-chip system for early cancer detection and post-therapy monitoring.

“Lab-on-a-chip technology crams an entire lab’s worth of functions into a tiny device roughly the size of a USB stick,” according to Built In.

Common uses for the technology include medical diagnostics, point-of-care testing, and environmental monitoring.

Lab-on-a-chip work being carried out at UH and elsewhere in Houston promises to revolutionize cancer detection and treatment. For instance, Houston biotech company iBiochips, a spinout from the Houston Methodist Research Institute, makes lab-on-a-chip devices that bolster cancer detection and therapy.

Four local organizations gain $10 million in CPRIT grants

Four other Houston-area organizations received an additional $10 million in grants in CPRIT’s latest round of funding:

University of Texas MD Anderson Cancer Center received two $2 million grants to recruit researchers Zheqi Li of Harvard University’s Dana-Farber Cancer Institute and Nikolaos Koundouros of Weill Cornell Medicine.
Rice University received one $2 million grant to recruit researcher Maria Akoppyan, formerly of the University of Southern California.
UT Medical Branch at Galveston received one $2 million grant to recruit researcher Cristina Santarossa of Johns Hopkins University.
Houston-based biopharma company Pulmotect received one $2 million grant to support better outcomes for cancer patients by activating immunity in the lungs as a first line of defense against germs.

The funding was part of $35 million in new CPRIT grants for institutions and companies across Texas approved at the organization's most recent meeting. To date, CPRIT has awarded more than $4.2 billion in grants.

“These awards support research across the cancer continuum from prevention to new classes of therapeutics,” said Dr. Scott Hiebert, chief scientific officer of CPRIT, said in a news release. “The work of these investigators will impact the lives of Texans across the state.”

Intuitive Machines lands $600M satellite deal, NASA ‘spacecraft bus’ contract

space deals

Houston-based space infrastructure company Intuitive Machines has scored two astronomical deals.

The deals add to the company’s soaring success. As of June 30, Intuitive Machines had a record-high $1.8 billion backlog of orders, a $1.5 billion increase from the end of last year. The current backlog includes orders for more than 80 spacecraft.

The company, which went public in 2023, expects this year’s revenue to total $900 million to $1 billion. In the first half of 2026, Intuitive Machines generated nearly $393 million in revenue.

Intuitive Machines estimates its total available market is valued at more than $150 billion.

$600 million-plus deal represents ‘important milestone’

On Monday, Intuitive Machines said it picked up a $600 million-plus deal to develop three commercial satellites for an undisclosed customer over the course of about two years.

Intuitive Machines says it will design, manufacture, set up and support several spacecraft “for a critical communications infrastructure mission.”

Steve Altemus, the company’s CEO, says the deal represents “an important milestone for Intuitive Machines and reflects the confidence our customers place in our ability to deliver high-performance spacecraft for a broad range of mission needs.”

Company nails down NASA deal for ‘spacecraft bus’

A day after announcing the $600 million-plus deal, Intuitive Machines said it secured a new contract with NASA.

Intuitive Machines says NASA’s Jet Propulsion Laboratory in Southern California will use the company’s IM 300 “spacecraft bus” for an EAGLE-VSWIR Earth observation mission. The mission is scheduled to launch in 2028.

Aside from supplying the IM 300 bus, Intuitive Machines will carry out mission support services.

The low-Earth-orbit mission will be equipped with Intuitive Machines’ hyperspectral visible to shortwave infrared (VSWIR) instrument. This technology sees colors and details that aren’t visible to the human eye.

The instrument is “designed to perform surface biology and geology observations from Earth orbit while demonstrating technologies that could support future lunar and Mars exploration missions,” Intuitive Machines says.

Intuitive Machines builds mission-critical spacecraft, systems, and infrastructure for business and government customers. To date, the company has produced more than 300 spacecraft, delivered over 575 pounds of payload to the moon and launched about 100 satellites.
