Houston startup rings NYSE closing bell

A Houston company got to take the national stage by ringing the closing bell at the New York Stock Exchange, and for Katie Mehnert, founder of ALLY Energy, it was a chance to reflect on the progress the industry as a whole has progressed.

"As I stood on the platform at the world’s largest stock exchange to ring the closing bell, surrounded by 130 people from across the energy industry, I saw it clearly: how the private sector will play a major role in getting us to an era of net zero," Mehnert writes in her guest column. Read the full piece here.

Deadline not to miss: ACCEL

Advancing Climatetech and Clean Energy Leaders Program, or ACCEL, has opened applications for it's second cohort. The program — from Greentown Labs and Browning the Green Space — provides access to funding, networking connections, incubation space, mentorship, resources, and opportunities for energy tech founders of color for a year.

“ACCEL is one of the most impactful, meaningful programs we’ve run to date,” Greentown Labs CEO and President Kevin Knobloch says in a news release. “We are eager to expand upon the great success and momentum of year one, and to welcome another incredible cohort of BIPOC-led startups that are developing much-needed climatetech solutions. We’re equally committed to helping these companies accelerate and deploy their solutions, while also helping to build a more diverse, inclusive climatetech workforce—ACCEL sits at the nexus of those two critical efforts.” Read more about the program.

Founder on ringing the NYSE bell and shining a spotlight on the future of energy in Houston

guest column

As I stood on the platform at the world’s largest stock exchange to ring the closing bell, surrounded by 130 people from across the energy industry, I saw it clearly: how the private sector will play a major role in getting us to an era of net zero. The people who power the energy industry will do the hard work. We’ve already begun. And we’re unafraid of the long journey ahead — something more than 40 of us exemplified that weekend by running a marathon.

The trip to New York City days ago was an exhilarating whirlwind. But it was also something much more: A chance to show the markets, the nation, and the world that Houston is leading the energy transition. (It didn’t hurt that we popped up on Good Morning America.)

From the beginning, the idea behind this pair of events — ringing the bell at the New York Stock Exchange and running the TCS New York City Marathon — was aimed at sending crucial messages. That recognizing climate change and building solutions is an obligation and an opportunity. That the energy industry understands this. That investors have good reason to support climate tech, one of the most exciting and fastest growing sectors. And, last but not least, that people’s perceptions of Houston as being all about oil and gas are simply wrong.

The dozens of us who gathered came from across the country and around the world, But by far, the largest contingent was from right here in Houston. Executives, engineers, entrepreneurs, and other innovators took part. People spearheading projects in every facet of energy, from wind to solar, carbon capture, and other methods of dramatically reducing carbon emissions. All as one team.

Those who traveled from “the energy capital” knew how important it was to highlight our Houston pride. As a new report from the Texas Climate Tech Collective points out, the biggest problem in the city’s climate tech ecosystem is its image. “Outsider perceptions of Houston often draw on negative stereotypes,” the report explains. “The number one disadvantage survey respondents chose – even more than access to VC capital – was Houston’s anti-climate reputation outside the state.”

It’s a problem I’ve been trying to combat for years, including through op-eds in national and international media outlets. Fortunately, the idea is starting to get through. Just days ago, the Financial Times reported that Houston claimed the top spot in this year’s FT-Nikkei Investing in America rankings by “moving beyond oil.” Our city, the paper said, “has become a hub for green energy innovation by building on its hydrocarbon past.”

Houston, and Texas a whole, should be immensely proud of this. But the energy industry has a long history of failing to tell its own stories. It’s time to change that. In fact, the recommendations in the collective’s report include “campaigning to improve Houston’s reputation, improving promotion of Houston’s energy transition initiatives and accomplishments, educating politicians and consumers, reversing anti-climate perception.”

Building bridges

All of the challenges we face, including the perception problem, will only be overcome if we work together. So the era of siloes must end. Climate change is an “all hands on deck” situation. This means companies large and small, as well as businesses focusing on all forms of energy, need to develop a “one-team” mentality.

We also need to step up our engagement with public sector entities. A great deal of public sector investment is being poured into renewable energy programs. Since I’ve served as an ambassador to the Department of Energy’s Equity in Energy initiative and a member of the National Petroleum Council, I’ve met many people in government who are eager to cooperate with us to help ensure that the United States leads the way in the energy transition.

The need for building these kinds of bridges is another reason that many of the participants in our Women & Allies in Energy team saw the New York City marathon as such a strong metaphor. It’s known for its bridges. And having run across all of them — and stopped for a quick selfie on the toughest one of all, the Queensboro Bridge — I’m reminded of their importance. I was happy to see that another recommendation in the collective’s report speaks directly to this. It calls for, “Building bridges between public and private, energy corporates and startups, universities and startups, and startups and mentors; seeking partnerships with other ecosystems; improving resources for early stage startups.”

We also need to build bridges among groups of people. More than ever, the industry needs diversity, equity and inclusion. (See my recent piece for Fast Company about why the C-Suite should double down, not shy away from, DEI.) We need to welcome people with all sorts of backgrounds, experiences, and perspectives. The greatest form of capital the energy sector has in building the future is not financial. It’s human capital. And the greatest natural resource we have is not one form of energy. It’s the people whose hard work, creativity, collaboration, and grit will get us to the finish line.

To help make all this happen, I’m calling for Houston to come together on climate change. Capitalizing on the annual Climate Week in New York City, and building on an event the City of Houston organized in 2021, let’s bring all industries and all people together next fall to show that we recognize climate reality, and are ready to take action together.

The next generation

While I did have the chance to lead the delegation at the NYSE closing bell, I did not hold the gavel — at least, not by myself. Instead, I handed it to my 12-year-old daughter, Ally. (Yes, her name is a big part of the inspiration behind our company name, ALLY Energy.)

As leaders in energy, we have to keep our eyes firmly focused on the next generation. This means not only giving them a strong supply of energy and healthier conditions on the planet. It also means giving them future job opportunities.

It’s up to us to build the pipeline for future talent. We need to improve STEAM (science, technology, engineering, arts and math) education. And we need to demonstrate to people who are currently underrepresented in our industry — such as women and members of minority groups — that they have a future in the world’s most exciting industry.

We can do this. We can get out of our bubble, show our Houston pride to the world, and lead the way to “energy 2.0” — an era of plentiful energy supplies and net-zero emissions. After all, dozens of us have returned from New York City with a mission: capitalize on all that momentum, join together as a team, and run the race to net zero.

Tesla unveils new Roadster sports car, which can thrust itself in the air

Tesla Talk

Tesla has unveiled its new Roadster sports car, which can thrust itself in the air, among other engineering bells and whistles. But drivers shouldn't expect to take it for a spin anytime soon.

Elon Musk's electric car company rolled out its second-generation Roadster at a Thursday event, showing off a set of cold gas thrusters and a “multi-mode” suction system that can fling the car in the air for short spurts and spin the vehicle mid-flight.

“Turns out the future does have flying cars,” Musk, Tesla's CEO, wrote on his social media platform X shortly after.

That future could be a ways off, however, given the regulatory hurdles for flying vehicles and the tangle of state rules that still need to be met.

“I’m not sure every state is going to allow a driver in the middle of traffic to suddenly elevate himself and fly," said David Vladeck, a Georgetown Law professor and former director of the FTC’s Bureau of Consumer Protection. “There is going to be a long process to let anything like that on a road.”

Thursday's event was hosted at the Texas rocket testing and development center for SpaceX — Musk's publicly-traded rocket company — and Tesla's executives noted that they “borrowed” some SpaceX technology to get the new Roadster in the air. Beyond quick jumps and flips, Tesla also said the car can accelerate from zero to 60 miles (96.6 km) an hour in less than a second.

This launch arrived after years of delays and anticipation around the new Roadster — and Tesla shares climbed in morning trading on Friday before falling amid a sell-off in companies tied to artificial intelligence.

The wait isn't completely over. Musk said production for consumers won't begin until 2028. Tesla also didn't immediately set a price tag on its latest EV.

Tesla was taking reservations for Roadster “rocket” car purchases on its website Friday morning, though the fine print said there was no guarantee when the vehicle would be delivered — or whether it would be delivered at all.

Bryant Walker Smith, former vice chair of a Department of Transportation advisory group on innovation, was unimpressed — though he did note Musk's ability to keep Tesla's stock high.

“This was a demonstration of a one-off car using a technology around for many years and will not be coming to public roads in 2028," said Smith, a law professor at the University of South Carolina. “Tesla pretty uniquely has been able to sell itself on a future that is an order of magnitude greater than reality.”

Musk has repeatedly said that the future of driving will be autonomous — and Austin-based Tesla has focused much of its business on building out self-driving features for its vehicles and, more recently, launching its own (still limited) robotaxi business.

But the company maintains that the Roadster will be made to have humans behind the wheel, calling the EV the “best of the last human-driven cars.”

Thursday's demo was technically autonomous “to make sure we don’t kill anyone,” Musk noted. But long-term, he said, the new Roadster will be “the only manually driven car that Tesla makes.”

“This is not necessarily a safety-optimized car,” Musk later added, met by laughter from the audience. But “it takes the fun meter to 11 out of 10.”

Tesla's first Roadster was launched back in 2008. And in 2018, Musk went as far as placing one on a rocket — with a mannequin dubbed “Starman” in the driver's seat — and launching it into space.

Again, the second-generation Roadster isn't immediately hitting the market. And whether the ambitious new vehicle boosts the company's bottom line remains to be seen.

In second-quarter earnings reported over the summer, Tesla's profits fell as the company spent more on research and development for its robotaxi and robotics businesses — which cut into money made from an otherwise sharp increase in vehicle sales. Net income totaled $1.11 billion for the period, while revenue climbed to $28.24 billion.

TEX-E names New Climate Ventures as latest expert in residence

energy mentors

Texas Exchange for Energy & Climate Entrepreneurship (TEX-E) has named its latest expert in residence.

The Houston-based energy transition nonprofit recently announced that New Climate Ventures will join the newly established program. The Expert-in-Residence partnership aims to connect TEX-E Fellows with "the people and organizations shaping the future of energy and entrepreneurship," the nonprofit previously announced.

Taylor Chapman, an investment principal at New Climate Ventures, sits on TEX-E's board of directors. New Climate Ventures invests in early-stage startups building next-gen technologies in the energy, materials and fuels sectors. The venture capital firm's portfolio includes Houston-based clean energy startups like Solidec, Syzygy Plasmonics and Rheom Materials.

“If you know me, you know that I'm passionate about ensuring that my beloved hometown, Houston, is the energy capital of the future — not just of the past," Chapman said in a LinkedIn post. "TEX-E is building a key piece to ensure that's the case: a strong pipeline of graduate and college students immersed [and] versed in the world of energy [and] climate entrepreneurship."

TEX-E says the partnership with New Climate Ventures will allow its fellows opportunities to learn from investors that work with emerging companies and understand how they evaluate new technologies.

TEX-E announced Houston-based geothermal unicorn Fervo Energy and venture capital firm Mercury Fund as its first experts in residence in August. At the time, it said the partnerships would allow its fellows to network and work with Tim Latimer, CEO of Fervo; Sarah Jewett, COO of Fervo; and Blair Garrou, managing partner of Mercury Fund.

The nonprofit was founded in 2022 through partnerships with MIT Martin Trust Center for Entrepreneurship and Greentown Labs. It works with university students from six schools: Rice University, University of Houston, Prairie View A&M University, The University of Texas at Austin, Texas A&M University and MIT.

Rice University spinouts named among 50 top cleantech companies to watch

green team

Two Rice University spinouts, Coflux Purification and DexMat, appear on a new list of the world’s 50 cleantech companies to watch.

Cleantech Group’s 2026 Cleantech 50 to Watch list recognizes early-stage companies “creating groundbreaking solutions to address some of the world’s most pressing environmental and sustainability challenges.”

Cleantech Group, a market research, consulting, and events company, selects the 50 honorees based on insights from analysts and early-stage innovators, along with public nominations.

Destroying “forever chemicals”

Coflux, founded in 2024, offers an onsite treatment system that captures and destroys manufactured “forever chemicals”—per- and polyfluoroalkyl substances—in water and wastewater. It’s a member of Greentown Houston.

Alec Ajnsztajn, CEO; Jeremy Daum, chief technology officer; and Dana Vazquez, chief commercial officer, co-founded Coflux. Ajnsztajn and Daum earned doctoral degrees from Rice, and Vazquez earned an MBA from the university.

Coflux spun out of Rice labs directed by professors Rafael Verduzco and Pulickel Ajayan.

Last year, Coflux received a $175,000 grant from the U.S. Food and Drug Administration’s National Institute of Food and Agriculture. The startup has also raised more than $500,000 in non-dilutive funding, including $80,000 awarded in 2024 by Rice’s One Small Step Grant program.

Promoting an alternative to copper

DexMat, founded in 2015, produces carbon nanotube products such as fibers, yarns, cables, and fabric. The company’s products address demand for materials that can reduce carbon emissions, according to CB Insights.

Its main product, Galvorn, is a copper alternative made of carbon nanotube fibers. CB Insights says Galvorn is engineered to be lighter and stronger than traditional conductive materials like carbon and steel. It’s used in industries such as energy, aerospace, defense, automotive, consumer electronics, and health care.

DexMat emerged from Matteo Pasquali’s Carbon Lab at Rice. Pasquali, co-founder of DexMat, co-invented the company’s technology with the late Nobel Prize-winning chemist Rick Smalley. Smalley was a professor of chemistry, physics, and astronomy at Rice.

Pasquali is a professor of chemical and biomolecular engineering, chemistry, materials science, and nanoengineering at Rice. He co-founded DexMat with Rice graduate Dmitri Tsentalovich, the company’s director of product innovation.

Earlier this year, DexMat raised $5 million in seed funding from Non Sibi Ventures, Governance Partners, Tailwind Futures, BetterWay, Capital Factory, and other investors. The company also secured $3 million in non-dilutive funding.

In 2023, DexMat raised $3 million in a pre-seed round led by Shell Ventures.
