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.

9 startups join Houston climatech accelerator to tackle carbon capture, energy efficiency, and more

new to hou

Greentown Labs closed out the second quarter with the addition of 17 startups, and just over half are collaborating with the Houston location.

The technology represented by the new additions span the industries of energy, agriculture, and manufacturing, with a focus on carbon capture, electrical usage efficiency, and resource accessibility.

Carbon capture

Two of the newest Houston members, Capture6 and C-Quester, are also part of the Carbon2Value Initiative, a global partnership between the Greentown Labs, Urban Future Lab in New York, and Fraunhofer, headquartered in Michigan. C2V focuses on accelerating technology solutions that capture carbon dioxide for conversion into value-adding products and services.

Similar to the way a sponge is moistened and later wrung out, C-Quester pulls CO2 from flue gas into a temperature-sensitive material that can be heated later to release carbon, making the storage and transport of CO2 easier to manage.

Capture6 uses CO2 pulled from the atmosphere through their Direct Air Capture technology in combination with water treatment methodologies to remove excess salinity from saltwater and brine, resulting in greater freshwater recovery, usable elements for a variety of industries, and carbonates transformed into mineralized form to prevent continued carbon emissions.

Energy efficiency

The Helix MICRA filters created by Helix Earth Technologies can remove CO2 from power plants and other pollutants commonly encountered in the shipping industry. The filtering technology, initially developed for NASA, also dehumidifies air conditioning systems for more efficient energy use.

H2PRO uses its water-splitting technology, E-TAC, to produce green hydrogen in a two-step process that requires less energy to perform than the more common process of electrolysis with improved safety aspects.

Steam production and distribution get an upgrade with Imperium Technologies, the first electromechanical solution that enables previously unseen systems monitoring for reduction in greenhouse gas emissions by 20 percent, on average.

With a keen focus on predictive insights, eologix deploys smart sensors to give operators advance warning of situations that could cause rotor imbalances to keep wind turbines – and the energy they produce – optimized.

Resource accessibility

NW NA supports the goals of stability, predictability, and accessibility of electric-powered vehicle use with its high-power EV-charging station, mobile electricity storage units, and renewable energy measurement and forecasting tool.

From the Metaversity under development, to its oil and gas line leak detection systems, Kauel goes all-in on AI for its clients, even helping children with kinesthetic rehabilitation through augmented and virtual reality programs.

Finally, SkyH2O brings fresh, clean water to areas with limited access to existing infrastructure or natural water resources for commercial, military, and industrial use.

Another eight startups join the cohort named above as members of the Greentown Labs Boston location: Capro-X, Carbon2Stone, Cottage, Dioxycle, enaDyne, Global Algae Innovations, Terrafixing, and Thola.

Houston medtech firm secures $30M for neurosurgical robot

stroke surgery

Robotic neurosurgery is an exciting new frontier in medicine, and Houston-based medtech firm XCath is leading the charge with its revolutionary Iris robotic system. The company announced in March that it had secured $30 million in Series C funding to continue developing systems to tackle blood clots in the human brain.

“We are grateful to our investors for their conviction in our shared mission to improve clinical outcomes for patients impacted by endovascular diseases,” Eduardo Fonseca, CEO of XCath, said in a news release. “In 2025, the XCath team advanced the frontiers of endovascular robotics. This funding accelerates our commitment to expanding access to life-saving care so that where a patient lives no longer determines whether they live.”

XCath–which also has campuses in Pangyo, South Korea–has already achieved a number of remarkable firsts in robotic neurosurgery. The Iris is the only endovascular robotic system currently in development to perform intracranial navigation or neurointerventional treatment, and is the only robot in the world to have performed an intracranial neurovascular procedure involving the robotic manipulation of three devices.

These new Series C funds, which bring the company's total investment to $92 million, will go toward developing a clinical telerobot capable of performing a mechanical thrombectomy. This would bring unprecedented accuracy and precision to the surgical removal of brain clots, significantly reducing the risk of neurosurgery.

“Robotic surgery succeeds when innovation is paired with practical execution,” Dr. Fred Moll, chairman of the XCath board of directors, said in the release. “XCath has built a promising technology foundation, and just as importantly, a team that values rigor and appreciates perspective. I’m excited to support them as they take on the mission of globalizing access to gold-standard care for stroke patients.”

In November 2025, the Iris debuted under the control of Dr. Vitor Mendes Pereira at The Panama Clinic in Panama City, alongside local Principal Investigator Dr. Anastasio Ameijeiras Sibauste. It was only the second time in human history that a robot had been used for intracranial neurovascular intervention, and it established Iris as a viable technology in the fight against stroke.

“Treatment of stroke and other neurovascular diseases represents one of the most significant financial opportunities in healthcare, supported by positive reimbursement dynamics and strong demand from health systems,” Nicholas Drysdale, CFO of XCath, added in the release. “With our continued investor support and disciplined capital deployment, XCath is positioned to build a category-leading platform in endovascular robotics”.

Houston geothermal unicorn Fervo officially files for IPO

going public

Fervo Energy has officially filed for IPO.

The Houston-based geothermal unicorn filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission on April 17 to list its Class A common stock on the Nasdaq exchange. Fervo intends to be listed under the ticker symbol "FRVO."

The number and price of the shares have not yet been determined, according to a news release from Fervo. J.P. Morgan, BofA Securities, RBC Capital Markets and Barclays are leading the offering.

The highly anticipated filing comes as Fervo readies its flagship Cape Station geothermal project to deliver its first power later this year

"Today, miles-long lines for gasoline have been replaced by lines for electricity. Tech companies compete for megawatts to claim AI market share. Manufacturers jockey for power to strengthen American industry. Utilities demand clean, firm electricity to stabilize the grid," Fervo CEO Tim Latimer shared in the filing. "Fervo is prepared to serve all of these customers. Not with complex, idiosyncratic projects but with a simplified, standardized product capable of delivering around-the-clock, carbon-free power using proven oil and gas technology."

Fervo has been preparing to file for IPO for months. Axios Pro first reported that the company "quietly" filed for an IPO in January and estimated it would be valued between $2 billion and $3 billion.

Fervo also closed $421 million in non-recourse debt financing for the first phase of Cape Station last month and raised a $462 million Series E in December. The company also announced the addition of four heavyweights to its board of directors last week, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE.

Fervo reported a net loss of $70.5 million for the 2025 fiscal year in the S-1 filing and a loss of $41.1 million in 2024.

Tracxn.com estimates that Fervo has raised $1.12 billion over 12 funding rounds. The company was founded in 2017 by Latimer and CTO Jack Norbeck.
