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 Innovation Awards to honor Wade Pinder as 2025 Trailblazer

And the award goes to...

On Nov. 13, we'll gather for the 2025 Houston Innovation Awards to celebrate the best and brightest in Houston innovation right now. And, as is tradition with the annual program, we'll honor one longstanding Houston innovator with the Trailblazer Award.

The award was established to recognize an individual who has left a profound impact on Houston's business and innovation ecosystem and is dedicated to continuing to support Houston and its entrepreneurs. The recipient is selected by our esteemed panel of judges from a pool of internal and external recommendations.

The 2025 Trailblazer Award recipient is Wade Pinder of Product Houston. A familiar face to those active in Houston's innovation sector, Pinder identifies as an "Ecosystem Wayseeker" and is the founder of Product Houston.

Pinder, a former product manager at Blinds.com, arrived in Houston in 2008 and has been deeply engaged in Houston’s startup and innovation scene since 2012. Over the years, he has supported hundreds of founders, product leaders, and community builders across the Houston area.

In 2023, he was honored as Mentor of the Year in the Houston Innovation Awards. Today, he fosters collaboration, clarity, and connection through his work at Product Houston, and he helps innovators find their place in the local sector via his monthly "Houston Ecosystem Mapping" sessions.

Read below for Pinder's insightful takes on the Houston innovation scene and what it means to blaze a new trail. Then, join us as we celebrate Pinder and all of our nominees and winners at the 2025 Houston Innovation Awards on Nov. 13 at Greentown Labs. Tickets are available now.

InnovationMap: Describe the growth of the Houston innovation ecosystem from your arrival in 2008 to now.

Wade Pinder: When I first arrived in Houston in 2008, the innovation ecosystem was more fragmented than it is today. Connecting with other innovators often meant attending a lot of hit-or-miss events. Over the years, it’s been incredible to see the network take shape and grow into a true community. I’ve had the privilege of being involved with several coworking spaces and accelerator programs along the way, and it’s been especially exciting to see Station Houston evolve into what is now the Ion District. What makes the Ion unique is how it blends openness and opportunity… ideas spill into and out of the space, and anyone can walk in, participate in programming, and find themselves in proximity to people who might help them take the next steps.

Additionally, the expansion of spaces like Texas Medical Center Innovation, Helix Park, The Cannon, and many others, have broadened Houston’s innovation landscape in powerful ways.

Today, when someone new moves to Houston and wants to plug into the startup and innovation scene, it’s much easier for them to find their way than when I moved here in 2008. I think that’s something Houston can really be proud of.

IM: As someone who engages with the broader Houston innovation community on a regular basis, what are the shared characteristics and traits that you see among its members?

WP: One of the things that makes Houston’s innovation community unique is how deeply it’s rooted in industry. So many of the innovators I meet come from within Houston’s major sectors, and they’ve seen firsthand where opportunities lie, which gives their innovation a certain practicality. They’re developing solutions that solve real, often complex, business and industry problems, not chasing trends or trying to create the next flashy consumer app.

What I admire most is that this community is growing in its understanding of the value of collaboration. They work with the systems and expertise that already exist, and find better ways to make them work together. Another shared trait I see across Houston’s innovators is a deep sense of curiosity and a drive to question the status quo while looking for better ways to build, improve, and solve.

IM: You’ve said, "Houston has Houston problems, and Houston needs Houston solutions." How do you see this taking shape in the innovation sector right now?

WP: When I first started getting connected to Houston’s startup and innovation scene in 2012, I noticed folks had a tendency to look at other cities and ask, "How can we do what they did?" Back then, we saw phrases like "Silicon Bayou" pop up, and while that enthusiasm was hopeful, it often discounted the things that make Houston unique. Over time, I’ve come to believe that the better question is: "What are we already great at, and how can we innovate from there?" The flip side of that question is to reflect on the things that hold us back as an ecosystem… identifying the friction points and finding practical ways to smooth them out.

From my time wandering around our ecosystem, I’ve come to understand Houston is great at infrastructure at scale, solving life-and-death challenges in the global spotlight, and "boldly going where no one’s gone before." These three things, in my opinion, capture the essence of Houston does best: We do hard things here.

What excites me today is that we’re applying innovation to those core strengths in ways that feel authentically Houston. One area I’m especially excited about is the emergence of the “New Space Economy,” captured beautifully in Wogbe Ofori’s thought piece “The Astropreneur’s Startup Journey Map.” It's a great example of how the next wave of space-related innovation might connect to Houston’s long-standing strengths in manufacturing, logistics, and problem-solving at scale.

Another challenge Houston faces is what I call a "proximity problem." Even when events are only a few miles apart, traffic can make it difficult for people to stay connected across the city. That’s why I’m so encouraged by the rise of what I think of as "intent-based gatherings" around the city: events designed with purpose, where people know they’ll find real connection and value once they arrive.

IM: Finally, what does being a "Trailblazer" mean to you?
WP: To me, trailblazing in the Houston innovation ecosystem means being willing to wander through the many different corners of the community and look for value in places we often overlook. It’s about showing up at events, community meetings, and pitch competitions — not just to participate, but to notice how each of these "nodes" in the ecosystem connects and adds value to the others.

Sometimes the trailblazer only walks a trail once: as they are discovering it. If you can help others see a newfound trail’s purpose and potential, it becomes a path others can follow more easily in the future. That’s the real work of a trailblazer: mapping connections, framing their value, and helping people recognize how those pathways strengthen the ecosystem as a whole.

In a broader sense, trailblazing is about seeing things not just as they are, but as they could be. Then taking the steps, however small, that make that vision real.

Houston-area VC funding sunk to 5-year low in Q3 2025, report says

by the numbers

Fundraising for Houston-area startups experienced a summertime slowdown, sinking to a five-year low in the third quarter, according to the latest PitchBook-NVCA Venture Monitor.

The PitchBook-NVCA Venture Monitor shows startups in the Houston metro area attracted $204.4 million in venture capital from June through August. That’s 55 percent below the total for the previous quarter and 51 percent below the total for the third quarter of 2024.

More telling than those figures is that the third-quarter haul dropped to its lowest total for Houston-area startups since the fourth quarter of 2020, when $133.4 million in VC was raised. That was the third full quarter after health officials declared the pandemic in the U.S.

In Q3 2025, AI accounted for nearly 40 percent of VC deal volume in the U.S., Kyle Stanford, director of U.S. venture research at PitchBook, said in the report. And through the first nine months of 2025, AI represented 64 percent of U.S. deal value.

VC deal activity “has been nearly steady, emphasizing a consistent influx of companies, especially at the pre-seed and seed stages,” Stanford said. “Large deals remain the primary driver of market deal value, with almost all of these deals focused on AI.”

Bobby Franklin, president and CEO of NVCA, said that while fundraising hasn’t returned to pre-pandemic highs, deal values are going up in sectors such as AI, manufacturing, robotics and space tech, many of which have already exceeded their investment totals for all of 2024.
