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.

Houston Energy and Climate Startup Week announces 2025 dates, key events

comeback tour

Six local organizations focused on the energy transition have teamed up to bring back Houston Energy and Climate Startup Week.

The second annual event will take place Sept. 15-19, according to an announcement. The Ion District will host many of the week's events.

Houston Energy and Climate Startup Week was founded in 2024 by Rice Alliance for Technology and Entrepreneurship, Halliburton Labs, Greentown Labs, Houston Energy Transition Initiative (HETI), Digital Wildcatters and Activate.

“Houston Energy and Climate Startup Week was created to answer a fundamental question: Can we achieve more by working together than we can alone?” Jane Stricker, senior vice president at the Greater Houston Partnership and executive director of HETI, said in the release.

So far, events for the 2025 Houston Energy and Climate Startup Week include an introduction to climatetech accelerator Activate's latest cohort, the Rice Alliance Energy Tech Venture Forum, a showcase from Greentown Labs' ACCEL cohort, and Halliburton Labs Pitch Day.

Houston organizations New Climate Ventures and Digital Wildcatters, along with Global Corporate Venturing, are slated to offer programming again in 2025. And new partners, Avatar Innovations and Decarbonization Partners, are slated to introduce events. Find a full schedule here.

Other organizations can begin entering calendar submissions starting in May, according to the release.

Last year, Houston Energy and Climate Startup Week welcomed more than 2,000 attendees, investors and industry leaders to more than 30 events. It featured more than 100 speakers and showcased more than 125 startups.

"In 2024, we set out to build something with lasting impact—rooted in the ingenuity of Houston’s technologists and founders. Thanks to a collaborative effort across industry, academia, and startups, we’ve only just begun to showcase Houston’s strengths and invite others to be part of this movement," Stricker added in the release. "We can’t wait to see the city rise to the occasion again in 2025.”

Dow aims to power Texas manufacturing complex with next-gen nuclear reactors

Clean Energy

Dow, a major producer of chemicals and plastics, wants to use next-generation nuclear reactors for clean power and steam at a Texas manufacturing complex instead of natural gas.

Dow's subsidiary, Long Mott Energy, applied Monday to the U.S. Nuclear Regulatory Commission for a construction permit. It said the project with X-energy, an advanced nuclear reactor and fuel company, would nearly eliminate the emissions associated with power and steam generation at its plant in Seadrift, Texas, avoiding roughly 500,000 metric tons of planet-warming greenhouse gas emissions annually.

If built and operated as planned, it would be the first U.S. commercial advanced nuclear power plant for an industrial site, according to the NRC.

For many, nuclear power is emerging as an answer to meet a soaring demand for electricity nationwide, driven by the expansion of data centers and artificial intelligence, manufacturing and electrification, and to stave off the worst effects of a warming planet. However, there are safety and security concerns, the Union of Concerned Scientists cautions. The question of how to store hazardous nuclear waste in the U.S. is unresolved, too.

Dow wants four of X-energy's advanced small modular reactors, the Xe-100. Combined, those could supply up to 320 megawatts of electricity or 800 megawatts of thermal power. X-energy CEO J. Clay Sell said the project would demonstrate how new nuclear technology can meet the massive growth in electricity demand.

The Seadrift manufacturing complex, at about 4,700 acres, has eight production plants owned by Dow and one owned by Braskem. There, Dow makes plastics for a variety of uses including food and beverage packaging and wire and cable insulation, as well as glycols for antifreeze, polyester fabrics and bottles, and oxide derivatives for health and beauty products.

Edward Stones, the business vice president of energy and climate at Dow, said submitting the permit application is an important next step in expanding access to safe, clean, reliable, cost-competitive nuclear energy in the United States. The project is supported by the Department of Energy’s Advanced Reactor Demonstration Program.

The NRC expects the review to take three years or less. If a permit is issued, construction could begin at the end of this decade, so the reactors would be ready early in the 2030s, as the natural gas-fired equipment is retired.

A total of four applicants have asked the NRC for construction permits for advanced nuclear reactors. The NRC issued a permit to Abilene Christian University for a research reactor and to Kairos Power for one reactor and two reactor test versions of that company's design. It's reviewing an application by Bill Gates and his energy company, TerraPower, to build an advanced reactor in Wyoming.

X-energy is also collaborating with Amazon to bring more than 5 gigawatts of new nuclear power projects online across the United States by 2039, beginning in Washington state. Amazon and other tech giants have committed to using renewable energy to meet the surging demand from data centers and artificial intelligence and address climate change.
