It’s not every day that an entrepreneur gets grilled on their go-to-market-plans by a former presidential candidate, but for a few nascent businesses, that’s just what happened last Friday at Greentown Labs Houston.

Grilled is perhaps too strong a term, as Andrew Yang, an entrepreneur turned politician, conversed convivially with a half-dozen growing businesses in the thriving Innovation Corridor seated in midtown Houston. Yang listened carefully to each company’s elevator pitch, interrupting only to exclaim, “that’s so cool!” and “congratulations, man!” like an awestruck coed before asking thoughtful questions about the journey ahead for each entrepreneur.

Lara Cottingham, vice president of strategy, policy, and climate impact at Greentown Labs Houston, set the tone for the tour with an overview of Greentown Labs and the entrepreneurial efforts in energy transition it supports.

“[Greentown Labs was] founded 12 years ago. We’ve supported about 550 startups. Our startups have created over 24,000 jobs – and that’s just in Boston and Texas,” says Cottingham. “We don’t really know how to fully measure everywhere, but they are operating globally.

“Our startups have raised about $4 billion dollars. Half of that was last year,” Cottingham continues. “When we talk about now being the time to be in climatetech, now is the time.”

The tour begins with WIP International Services, a start up solving the problem of thirst and water scarcity by extracting moisture from humid environments and converting it into usable water.

“We can produce a purely distilled product, or a mineralized, pH balanced product for potable water,” explains Tracy L. Jackson, CEO of WIP International Services LLC.

The small group tagging along with Yang cheers the idea of creating clean water to drink while lowering the humidity of their homes, and effectively, their demand on energy for air-conditioning in a city that is now well into three-digit summer temperatures with average outdoor humidity above 70 percent.

Jackson almost stumbled into her startup by accident 8 years ago. She was visiting a site in Louisiana working on algae solutions, where she encountered an earlier (and much larger and noisier) model of the unit that stood in front of her now, no bigger than a standard water cooler. Inspired by scenes she witnessed in Africa during her tenure with an oilfield services company, Jackson knew this was a solution too good to keep quiet.

“Because I had been in Africa – I worked in an oil and gas services company – I had seen people standing in line for water from a water well in a village. And I thought, ‘this would be perfect for that situation,’” Jackson tells the tour group. “We now have developing relationships in Africa as well as Mexico on large scale projects for atmospheric water generation.”

At the next stop, Reid Carrazzone, president and CEO of Top Grain Technologies, softly explains how he and Zack Cordero, chief scientific officer, address the challenges of long-lead times and harsh environments impeding the ability to get hydrogen-fired turbines 100 percent hydrogen-fired.

“We are commercializing a heat treatment invented at MIT that will enable 3D-printed metal materials to serve in combustion turbine engines,” Carrazzone tells Yang. “Traditionally, 3D-printed metals are not well-suited to serving the environments of high temperature/high stress that you’d find in jet engines and natural gas settings.

“These [3D-printed] materials, certain classes of them, can be uniquely hydrogen-compatible, as well as have temperature capabilities in excess of the existing materials today,” Carrazzone says. “They will need our heat treatment to bridge that final gap in properties.”

Yang lights up with at the prospect that the duo may have come up with a truly unique solution, even suggesting the company may be in a name-your-own-price situation. The Top Grain Technologies team accepts the compliment with humility, insisting it’s more about solving the simple problems one step at a time.

Companies that Yang met along the Greentown Labs workshop floor represent just a fraction of the innovation proliferating across Houston in recent years, each with a different focus on energy sustainability and the circular economy. Maybe one day Yang, Jackson, and Carrazzone will look back on this interaction and think, “I knew them when…” Only time, and continued tending to the entrepreneurial spirit, will tell.

Asking ChatGPT what all was made from petroleum produced surprising results - the answer: everything. Photo by Sanket Mishra/Unsplash

Energy truly IS everywhere according to ChatGPT

EVERYDAY ENERGY

I sat down to have a conversation with ChatGPT from OpenAI about energy by-products; specifically, everyday items we use that contain some form of petrochemicals. My first prompt was rather broad, so I wasn’t surprised to get back a rather broad answer highlighting product categories instead of specific examples. Plastics, synthetic fibers, cleaning products, personal care products, medicines, paints & coatings, and adhesives were all succinctly summarized, but I wanted to dive deeper.

Given that AI has an almost limitless reach, I asked for a comprehensive list of all the products we use in everyday life that are made from petrochemicals. Turns out, ChatGPT has some healthy boundaries, so it pushed back, only offering a slightly more detailed list of the categories produced from the first prompt.

Not to be deterred, I asked for additional examples. I didn’t want to continue getting spoon-fed 10 items at a time, so I asked for 200. Less than comprehensive, more than the crumbs I was getting.

In entertaining fashion, ChatGPT told me compiling a list of 200 items might be challenging, but that it could offer up 100. The brazen negotiation made me smile.

I complimented the list and nudged a bit, encouraging ChatGPT it could come up with another 100 items if it tried. Much like a teenager wishes to stave off further questioning from a nosy parent, ChatGPT proffered up a second response of 100 items–almost half of which were simply things before which it added the qualifier “synthetic.” Salty.

As my intention is not to bore you, but rather enhance the knowledge of our readers by understanding how pervasive petrochemical products are in our everyday life, I settled on a more direct inquiry with a capped demand prompt: “What would you say are the 10 most surprising things in common everyday use that contain petrochemical products?”

Most of the answers featured wax-based products, like lotions, crayons, and lipstick–not necessarily earth-shattering realizations given my familiarity with cosmetics as petroleum by-products. I was pleasantly surprised to learn that chewing gum, with its synthetic rubber base enabling theoretically endless chewing, is derived from petroleum. I was also surprised to learn that many artificial sweeteners, like saccharin and aspartame, are made from petrochemicals. Huh.

There was one item on the list, however, that helped me see how truly pervasive the energy industry is, and not just for petrochemicals. Tucked in nonchalantly at #6 was Deodorant. My brain jumped immediately to the waxy base of a solid sweat deterrent, but my eyes got a curveball. ChatGPT writes, “Many deodorants contain aluminum, which is often derived from bauxite, a mineral that is usually mined from the earth using petroleum-powered machinery.” Now that was an answer I wasn’t expecting.

While my initial inference stood true – the smooth glide of a buttery solid antiperspirant is without a doubt derived from petrochemicals (not to mention the plastic packaging surrounding it), I wasn’t expecting ChatGPT to rope in the oft petroleum-fueled tools used to make said product. If that’s true, then nearly every item on the planet is derived from petroleum. Or at the very least, some source of energy. Regardless of whether the machinery used runs on gasoline, electricity, or wind power, literally almost everything that is produced on this earth is related to the energy industry.

Even if it’s hand-made, it’s technically still energy-adjacent, assuming we all bathe regularly with soap, yet another on the list of commonly used items derived from petroleum by-products. It’s certainly directly powering some manual activities, for those busting stress and bad breath with gum, or drinking a diet soda to power through. No pun intended.

I share this amusing tale simply to clarify the ubiquitous nature of energy in all parts of the modern world. As we look toward the #futureofenergy, we must be cognizant of its universal reach. It’s not necessarily realistic to switch from one source of energy to another overnight, but we do have a responsibility to seek cleaner, healthier, more efficient sources of energy while sustaining the life to which we have all grown accustomed.

Much like ChatGPT thought she couldn’t come up with 200 items derived from petroleum products, many think Houston will be unable to drive the Energy Transition, given our extensive petroleum focus. But like so many fellow Houstonians before us, we love a good challenge.

Just keep prompting us, and we’ll eventually unlock infinite potential for the #futureofenergy. It’s a limitless time to be in Houston, absorbing wisdom the city so willingly wants to share with the growing ecosystem of innovators. Just ask the growing number of almost 5,000 Energy-related firms in Houston. We’re just getting started.

NERC warns of summer energy shortfalls–what you can do now

THINGS ARE HEATING UP

The North American Electric Reliability Council (NERC) issued a warning with the 2023 Summer Reliability Assessment yesterday – energy shortages could be coming this summer for two-thirds of North America if temperatures spike higher than normal.

“Increased, rapid deployment of wind, solar and batteries have made a positive impact,” Mark Olson, NERC’s manager of reliability assessments says in the release. “However, generator retirements continue to increase the risks associated with extreme summer temperatures, which factors into potential supply shortages in the western two-thirds of North America if summer temperatures spike.”

For Texans, the combined risk of drought and higher-than-normal temperatures could stress ERCOT system resources, especially in the case of reduced wind. But before there’s a mad rush on generators, keep in mind, electricity consumers can take simple actions to minimize the possibility of widespread shortfalls.

Electricity demand begins rising daily around 2 P.M. in the summer and peaks in the final hours of daylight. These hours are generally not only the warmest hours of the day but also the busiest. People return from work to their homes, crank down the air conditioner, turn on TVs, run a load of wash, and prepare meals using multiple electric-powered appliances.

If everyone takes one or two small steps to avoid unnecessary stress on the grid in the hours after coming home from work, we can prevent energy shortfalls. Modify routines now to get into the habit of running the dishwasher overnight, using the washer and dryer before noon or after 8 pm and pulling the shades down in the bright afternoon hours of the day.

Try to delay powering up devices – including EVs – until after dark. Turn off and unplug items to avoid sapping electricity when items are not in use. And if you can bear it, nudge that thermostat up a couple of degrees.

Energy sustainability demands consistent collaboration and coordination from every consumer of energy. Let’s get in the habit of acting neighborly now with conservative electricity practices before we start seeing temperatures–of both the literal and figurative kind–flare.

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.
