Houstonians are used to filtering their water, but few really ponder why they’re doing it.

“Most people, when they think about water stress, they think about water scarcity, like what you see happening in Northern Africa or maybe the Southern U.S.,” says Alexander von Welczeck, chairman, president and CEO of SkyH2O. “A bigger, creeping issue, particularly in the industrialized world, is water toxicity.”

Some Houston tap water contains “forever chemicals” that can be toxic, as some reports have found. In fact, says von Welczeck, water toxicity is a problem across the Gulf Coast. That’s why the California-based businessman has identified Houston as the first region to benefit from SkyH2O’s technology.

The company will break ground on its first SkyH2O Station in the first quarter of 2024 in Dickinson, strategically placed between Houston and Galveston. That will be followed by another in Angleton. Eventually, says von Welczeck, there will be eight SkyH2O stations in the greater Houston area.

Von Welczek describes a SkyH2O Station as bearing a resemblance to “a big, modern gas station, but as opposed to gas, the primary product is fresh, healthy water.” With everything from charging stations for electric vehicles to a farmers market-style set-up of sustainable food, the stations will indeed be like a futuristic gas station.

Water will be distributed both in recyclable packaging for smaller businesses and homes, and in bulk to fill water tankers for ranches and other larger customers. Von Welczeck foresees, for example, Galveston cruise ships filling up with a supply of water at that station.

But where will this fresh, clean water come from? SkyH2O uses atmospheric water generation, or AWG, systems to pull humidity from the air and turn it into potable water. The higher the humidity, the more water can be produced.

“Obviously in and around Houston, we have tremendous humidity,” von Welczeck says.

This is all done using the Maximus 4260, the latest and greatest of the company’s AWG systems. The machine is rated to produce 10,500 litres of fresh, potable water a day. It produces net zero water, meaning that it doesn’t come from any existing water resource.

What comes out initially is a semi-distilled, purified water. The next step is further filtering it and adding minerals to make the product potable for customers. Von Welczeck says that SkyH2O’s water meets the Texas Commission on Environmental Quality’s water standards.

The serial entrepreneur has been working in the climate tech space since 2002 and has a proven track record. Von Welczeck says that he sold his company, Solar Power Partners, to NRG in 2010.

“From my perspective, most everything in climate technology, whether it's clean energy, recycling, even food and water, they're all interrelated,” he says.

After opening around 20 Texas locations, von Welczeck has his sights set on covering the entire Gulf Coast. After that, he hopes to expand to Mediterranean Europe, particularly water-strapped islands. He’s even in discussions with potential clients in the Middle East. But Houston will be the first to taste SkyH2O’s potentially globe-altering water.

Energy Transition entrepreneurs make the most of heat, humidity at Greentown Labs Houston

meet and greet

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.

Solar surpasses coal to become ERCOT’s third-largest power source in 2025

by the numbers

Solar barely eclipsed coal to become the third biggest source of energy generated for the Electric Reliability Council of Texas (ERCOT) in 2025, according to new data.

In 2024, solar represented 10 percent of energy supplied to the ERCOT electric grid. Last year, that number climbed to 14 percent. During the same period, coal’s share remained at 13 percent.

From the largest to smallest share, here’s the breakdown of other ERCOT energy sources in 2025 compared with 2024:

  • Combined-cycle gas: 33 percent, down from 35 percent in 2024
  • Wind: 23 percent, down from 24 percent in 2024
  • Natural gas: 8 percent, down from 9 percent in 2024
  • Nuclear: 8 percent, unchanged from 2024
  • Other sources: 1 percent, unchanged from 2024

Combined, solar and wind accounted for 37 percent of ERCOT energy sources.

Looking ahead, solar promises to reign as the star of the ERCOT show:

  • An ERCOT report released in December 2024 said solar is on track to continue outpacing other energy sources in terms of growth of installed generating capacity, followed by battery energy storage.
  • In December, ERCOT reported that more than 11,100 megawatts of new generating capacity had been added to its grid since the previous winter. One megawatt of electricity serves about 250 homes in peak-demand periods. Battery energy storage made up 47 percent of the new capacity, with solar in second place at 40 percent.

The mix of ERCOT’s energy is critical to Texas’ growing need for electricity, as ERCOT manages about 90 percent of the electric load for the state, including the Houston metro area. Data centers, AI and population growth are driving heightened demand for electricity.

In the first nine months of 2025, Texas added a nation-leading 7.4 gigawatts of solar capacity, according to a report from data and analytics firm Wood Mackenzie and the Solar Energy Industries Association.

“Remarkable growth in Texas, Indiana, Utah and other states ... shows just how decisively the market is moving toward solar,” says Abigail Ross Hopper, president and CEO of the solar association.
