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.

Houston-based Syzygy lands global customer for first commercial SAF plant

clean fuel deal

Houston-based Syzygy Plasmonics has secured a major future customer for its sustainable aviation fuel.

Syzygy announced this week that it has entered into a capacity reservation agreement with World Fuel Services, a global fuel distribution and logistics company.

Through the deal, World Fuel has reserved a portion of Syzygy's SAF production for future plants slated for Central and South America. The clean fuel will be produced at Syzygy’s NovaSAF-1 facility in Uruguay, which is moving toward construction.

The NovaSAF-1 will be the world's first electrified facility to convert biogas into sustainable aviation fuel (SAF). The facility is expected to produce over 350,000 gallons of SAF annually, which would be considered “a breakthrough in cost-effective, scalable clean fuel,” according to Syzygy.

The facility is expected to produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel and make its first deliveries in 2028.

"Following NovaSAF-1, this agreement reflects continued interest in scalable pathways for producing SAF from biogas," Trevor Best, CEO of Syzygy Plasmonics, said in a news release. "Our NovaSAF platform is designed to deliver cost-competitive fuel while supporting the aviation sector's evolving regulatory and sustainability requirements."

Syzygy will make a portion of future production capacity available to World Fuel from its planned facilities, subject to the development and completion of those projects, according to the deal.

"We continue to evaluate supply opportunities that support increased access to lower carbon fuels in aviation, in line with emerging regulatory requirements and customer demand," Michael Ranger, senior vice president of supply EMEAA at World Fuel, added in the release. "Arrangements such as this are part of our ongoing efforts across the supply chain.”

Syzygy also secured an offtake agreement with Singapore-based commodity company Trafigura from NovaSAF-1 earlier this year.

Texas Gov. Abbott seeks data center crackdown as state grapples with growing power demand

growing pains

Just seven months ago, Gov. Greg Abbott trumpeted Google’s $40 billion plan to add three data center campuses in Texas. Now, amid growing public outcry over such projects, Abbott is pushing for a regulatory crackdown on data centers in the Lone Star State.

Abbott recently sent a letter to leaders of the Public Utility Commission of Texas (PUC) and the Electric Reliability Council of Texas (ERCOT) proposing stricter oversight of the state’s data centers. Texas is home to more than 400 data centers, with many more on the way, and is poised to become the world’s largest data center market.

Among other things, Abbott wants to:

  • Ensure residential electric bills go down — not up — as data centers connect to ERCOT’s grid, which supplies power for about 90 percent of Texans.
  • Require data centers to cover the costs of upgrades to deliver electricity to the power-hungry facilities.
  • Repeal sales tax exemptions and other “outdated or unnecessary” financial incentives for data centers.
  • Institute “best practices,” such as property setbacks and noise-reduction technology, to ease the impact of data centers on nearby residents.
  • Demand that all new data centers, which use a tremendous amount of water, be built with water-efficient technology.
  • Require large data centers to generate annual reports on their use of electricity and water.

Abbott has set a July 17 deadline for the PUC and ERCOT to address his recommendations.

“As Texas continues to welcome innovation and investment, we must ensure that growth strengthens our people and their quality of life without placing undue burdens on Texans and local communities,” Abbott wrote.

Abbott’s call for tighter control of data centers has elicited both praise and skepticism.

In a social media post on X, Texas House Speaker Dustin Burrows, a Lubbock Republican, thanked Abbott for seeking “accountability and reform” in the state’s data center industry. Burrows has made data centers one of his priority issues for the 2027 state legislative session.

State oil and gas regulator Wayne Christian, a member of the Texas Railroad Commission, weighed in with similarly positive comments about Abbott’s directive. He says an outright ban on data centers isn’t the answer to residents’ complaints about new facilities.

“The Texas way is not to answer innovation with government overreach or fear-driven bans,” Christian, whose agency wasn’t cited in Abbott’s letter, said in a statement posted on X. “Our job is to protect prosperity, safeguard taxpayers and ensure the infrastructure that powers our economy remains strong and reliable.”

Gina Hinojosa, an Austin Democrat who’s challenging Abbott in this November’s gubernatorial race, took issue with the governor’s edict on data centers.

“Greg Abbott is changing his tune on data centers because he knows his policies are unpopular,” Hinojosa, a state representative, wrote on X. “Nobody believes the arsonist is gonna be the one to put out the fire.”

Abbott’s call for stepped-up regulation of data centers echoes many of the concerns expressed by the state chapter of the Sierra Club, an environmental nonprofit.

“The growth of data centers reflects a broader transformation taking place across Texas,” the Sierra Club says on its website. “The state is becoming a hub for the technologies that will shape the future economy, from artificial intelligence to advanced computing and cloud services. At the same time, Texans deserve transparency about how these projects affect the communities where they are built.”

Fervo promotes strategy leader to COO as flagship geothermal project nears launch

new leader

Houston geothermal unicorn Fervo Energy has named Sarah Jewett as its new COO.

Jewett steps into the role as the company prepares for its flagship Cape Station geothermal project to deliver its first power later this year.

Jewett joined Fervo in 2020 as director of strategy and most recently served as the company's senior vice president of strategy. She spoke with HETI on the potential of geothermal energy in 2024.

Before Fervo, Jewett served as senior director of corporate development for Houston-based Select Energy Services. She ran hydraulic fracturing crews for Schlumberger in the Permian Basin and Alaska's North Slope early in her career.

In the COO role, Jewett is tasked with creating "the centralized infrastructure required to execute on what the company believes is the most significant commercial opportunity for clean, firm power in history," according to a company release.

“What Sarah has built over the last six years has been foundational to the company’s success. From the time she joined, she has brought an unwavering people-first mindset and outstanding dedication to building things that last,” Tim Latimer, CEO and co-founder of Fervo, added in the release. “As we move into the next phase of our growth, there is no better person to lead the operating core of this company.”

Jewett holds an MBA from Harvard Business School and a bachelor's degree in mechanical engineering from Dartmouth College.

Fervo announced the addition of four heavyweights to its board of directors this spring, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE. Shortly after, the company filed for its highly anticipated $1 billion-plus IPO. Read more here.
