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.

Gold H2 harvests clean hydrogen from depleted California reservoirs in first field trial

breakthrough trial

Houston climatech company Gold H2 completed its first field trial that demonstrates subsurface bio-stimulated hydrogen production, which leverages microbiology and existing infrastructure to produce clean hydrogen.

Gold H2 is a spinoff of another Houston biotech company, Cemvita.

“When we compare our tech to the rest of the stack, I think we blow the competition out of the water," Prabhdeep Singh Sekhon, CEO of Gold H2 Sekhon previously told Energy Capital.

The project represented the first-of-its-kind application of Gold H2’s proprietary biotechnology, which generates hydrogen from depleted oil reservoirs, eliminating the need for new drilling, electrolysis or energy-intensive surface facilities. The Woodlands-based ChampionX LLC served as the oilfield services provider, and the trial was conducted in an oilfield in California’s San Joaquin Basin.

According to the company, Gold H2’s technology could yield up to 250 billion kilograms of low-carbon hydrogen, which is estimated to provide enough clean power to Los Angeles for over 50 years and avoid roughly 1 billion metric tons of CO2 equivalent.

“This field trial is tangible proof. We’ve taken a climate liability and turned it into a scalable, low-cost hydrogen solution,” Sekhon said in a news release. “It’s a new blueprint for decarbonization, built for speed, affordability, and global impact.”

Highlights of the trial include:

  • First-ever demonstration of biologically stimulated hydrogen generation at commercial field scale with unprecedented results of 40 percent H2 in the gas stream.
  • Demonstrated how end-of-life oilfield liabilities can be repurposed into hydrogen-producing assets.
  • The trial achieved 400,000 ppm of hydrogen in produced gases, which, according to the company,y is an “unprecedented concentration for a huff-and-puff style operation and a strong indicator of just how robust the process can perform under real-world conditions.”
  • The field trial marked readiness for commercial deployment with targeted hydrogen production costs below $0.50/kg.

“This breakthrough isn’t just a step forward, it’s a leap toward climate impact at scale,” Jillian Evanko, CEO and president at Chart Industries Inc., Gold H2 investor and advisor, added in the release. “By turning depleted oil fields into clean hydrogen generators, Gold H2 has provided a roadmap to produce low-cost, low-carbon energy using the very infrastructure that powered the last century. This changes the game for how the world can decarbonize heavy industry, power grids, and economies, faster and more affordably than we ever thought possible.”

Rice University spinout lands $500K NSF grant to boost chip sustainability

cooler computing

HEXAspec, a spinout from Rice University's Liu Idea Lab for Innovation and Entrepreneurship, was recently awarded a $500,000 National Science Foundation Partnership for Innovation grant.

The team says it will use the funding to continue enhancing semiconductor chips’ thermal conductivity to boost computing power. According to a release from Rice, HEXAspec has developed breakthrough inorganic fillers that allow graphic processing units (GPUs) to use less water and electricity and generate less heat.

The technology has major implications for the future of computing with AI sustainably.

“With the huge scale of investment in new computing infrastructure, the problem of managing the heat produced by these GPUs and semiconductors has grown exponentially. We’re excited to use this award to further our material to meet the needs of existing and emerging industry partners and unlock a new era of computing,” HEXAspec co-founder Tianshu Zhai said in the release.

HEXAspec was founded by Zhai and Chen-Yang Lin, who both participated in the Rice Innovation Fellows program. A third co-founder, Jing Zhang, also worked as a postdoctoral researcher and a research scientist at Rice, according to HEXAspec's website.

The HEXASpec team won the Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2024. More recently, it also won this year's Energy Venture Day and Pitch Competition during CERAWeek in the TEX-E student track, taking home $25,000.

"The grant from the NSF is a game-changer, accelerating the path to market for this transformative technology," Kyle Judah, executive director of Lilie, added in the release.
