The high-speed railroad from Houston to Dallas has acquired a key new player that will run day-to-day operations.

Renfe, an international railway company based in Spain, has been hired by Texas Central, the project developers, as the train's operating partner. The selection of Renfe as an operating partner marks another major step forward for the Houston-to-North Texas high-speed railroad.

Texas Central CEO Carlos Aguilar says in a statement that Renfe was chosen after a review of the best railroad operators in the world.

"Renfe has established a reputation for excellence in railroad operation in Spain and across the world, and we welcome them aboard," Aguilar says. "With their decades of expertise, they were a natural fit to join our other partners. Having the operator, the design build, and technology teams all on board and able to collaborate will ensure all aspects of the railroad are integrated and efficient."

A release calls Renfe "one of the world's most significant railways operators," running 5,000 trains daily on 7,500 miles of track. The company is integral to the transport system in its home base of Spain, handling more than 487 million passengers and 19.6 million tons of freight moved in 2017.

Renfe, in partnership with Adif, which manages Spanish railway infrastructure, will be responsible for running the trains; maintaining system components, such as engines, signals, and other equipment; and overseeing ticketing, passenger loyalty programs, and other services.

It will also provide technical advice on the design and construction of the Texas train and assist in the further development of Texas Central's operation and maintenance plans, preparing the railroad for passenger service.

Renfe is one of the biggest companies in Spain, employing nearly 14,000 people and recording revenues of 3.6 billion euros in 2017. Its high-speed systems were used by more than 36 million passengers in 2017. In March, Renfe announced that it had posted a net profit of 70 million euros in 2017, thanks in part to a jump in the number of its high-speed passengers, chalking up five consecutive years of growth.

Renfe president Isaías Táboas says the deal is a boon for Texas and for the Spanish railway industry.

"Texas Central represents a large high-speed train project in a country with high-growth potential, for which the Spanish experience will be of great help," he says. "Both Renfe Operadora and Adif have accumulated years and miles of high-speed railway development with professional teams, extensive experience, and specialized knowledge. We are committed to the success of Texas Central in improving the mobility of Texans and others in the U.S."

The agreement comes about a week after Texas Central engaged multinational firm Salini Impregilo ­– operating in the U.S. market with The Lane Construction Corporation – to lead the civil construction consortium that will build the passenger line, including viaducts, embankments, and drainage.

Spain's first high-speed line between Madrid and Seville was dedicated in 1986 and Renfe's first high-speed service connected the cities in 1992.

Its second high-speed line, from Madrid to Barcelona, was completed in 2007. Renfe also operates high-speed service from Barcelona to Paris, Lyon, and Toulouse in France. Among other major international projects, Renfe operates the recently opened high-speed train between Mecca and Medina, in Saudi Arabia.

The 200-mph train will link Houston and Dallas in 90 minutes, with a midway stop in the Brazos Valley.

The Texas train will be based on the latest generation of Central Japan Railway's Tokaido Shinkansen train system, the world's safest mass transportation system. It has operated for more than 54 years with a perfect record of zero passenger fatalities or injuries from operations, and an impeccable on-time performance record.

Texas Central and its partners are refining and updating construction planning and sequencing, guided by the Federal Railroad Administration's recently released draft environmental impact statement. The FRA now is working on a final environmental review that will help determine the project's timeline and final route.

UT team develops wearable technology for atmospheric water harvesting

In The Air

Engineers at the University of Texas at Austin have developed a prototype jacket that harvests clean drinking water directly from the atmosphere, and it works even in the driest desert conditions.

The research, published in Science Advances, marks the latest milestone in nearly a decade of work by materials scientist and chair professor Guihua Yu and his team at the Cockrell School of Engineering's Walker Department of Mechanical Engineering and Texas Materials Institute. The wearable technology marks a significant leap: instead of a bulky, stationary machine, this jacket does the work.

"We have been working on atmospheric water harvesting technology for a number of years," Yu says. "This current version is even more wearable. We're transitioning from conventional, more stationary water harvesting to something truly portable and personal."

Yu's lab first published work on hydrogel-based water harvesting around 2019, and the jacket is the latest evolution of that platform, now called AirGel. Last year, the broader AirGel invention won the top prize in the graduate category of the National Collegiate Inventors Competition.

The jacket is woven with specially engineered hydrogel fibers; ultra-porous materials that attract and absorb moisture from the surrounding air much like a household desiccant. Unlike a desiccant, the material doesn't require intense heat to release that water. The hydrogel is thermally responsive, meaning a modest rise in temperature — even from mild solar heating — is enough to release the water it has captured.

Condenser test in AustinSo, somebody would be wearing the jacket, or perhaps carrying this gel-like textile as a blanket, as it passively absorbs moisture from the air. Then they would detach the textile panels and place them into a small, portable collector unit; essentially a compact heater. The water evaporates out of the textile, condenses inside the collector, and drips out as clean, drinkable water.

"It immediately becomes drinkable because it already goes through the distillation process," Yu explains.

In trials, the jacket produced between 400 and 900 milliliters of water per day depending on humidity, or roughly 14-30 ounces, nearly a quart, depending on the air's humidity. With one kilogram of the textile, the researchers found they could generate approximately 3.7-4 liters of water in arid conditions, and potentially double that in humid ones. So far, the team has tried the jacket out in very dry, semi-dry, and humid areas, and the jacket was able to pull water from each climate.

Lead researcher Chuxin Lei, a postdoctoral researcher on Yu's team and co-author on the paper, says the goal was to rethink who this technology could serve.

Portable bag contents

"Many current [atmospheric water harvesting] systems are still built as rigid or stationary platforms, making them less suitable for people who are moving, working outdoors, or operating in some remote environment. This lead us to ask whether we could build a water harvesting system that could become more like clothing — light, wearable, flexible, and naturally suited for personal use," Lei says.

The potential applications are wide-ranging. Yu's team has previously worked with the Department of Defense on water solutions for soldiers, where water logistics can be dangerous and costly. The technology could also serve hikers, emergency responders, disaster relief workers, and agricultural and field workers. Anyone who needs clean water on the go and far from infrastructure.

The team also sees a potential future where the technology complements large-scale centralized water systems rather than replacing them.

"Our solution cannot be a universal solution for all," Yu acknowledges. "But I think it's an extremely important alternative."

For now, the jacket is still a laboratory prototype, but Yu and Lei are optimistic. With the right industry partnerships, they say, the technology could realistically reach commercial scale within three to five years.

Houston ranks among world’s top 30 emerging startup ecosystems

Startup Status

Long known as the Energy Capital of the World, Houston also ranks among the world’s top 30 emerging startup ecosystems, according to a new report.

The report from Startup Genome, a research and advisory organization, doesn’t assign a specific numeric ranking to Houston’s startup ecosystem. Rather, it puts Houston in the ranking range of 21 to 30 for emerging ecosystems. Startup Genome weighed factors such as early-stage funding, performance and talent to identify the top emerging ecosystems.

Houston also gained notice for being one of the world’s 20 emerging ecosystems with at least four unicorn startups in the past 10 years. Houston and nine other ecosystems each had four unicorns.

According to StartupBlink, a startup research platform, Houston’s startup ecosystem grew 24 percent in 2025, with over 1,300 startups and total startup funding exceeding $808 million. StartupBlink places Houston at No. 46 among the world’s top 100 startup ecosystems.

In a recent post on LinkedIn, David Horsup, executive in residence at the Rice Alliance Clean Energy Accelerator, wrote that Houston “has all the ingredients to be wildly successful if it stays true to its differentiated pillars that drive the economy — energy, medical, and aerospace.”

Mumbai topped Startup Genome’s list of emerging ecosystems, followed by Istanbul, Madrid, Salt Lake City-Provo and Barcelona. After Salt Lake City-Provo, the top U.S. ecosystems were Phoenix, Detroit, Minneapolis and Las Vegas.

Silicon Valley led Startup Genome’s ranking of the world’s top established ecosystems, followed by New York City, London, Tel Aviv and Boston. Austin landed at No. 18 in this category and Dallas at No. 27.

“For much of the past decade, this report has chronicled the welcome dispersion of opportunity beyond the traditional hubs,” Startup Genome writes. “That trend has not died — but it has been complicated. Capital and scale are consolidating once more, particularly in the United States, and the gap between leading and emerging ecosystems is widening.”

KBR names C-suite duo to lead $5.3B government services spinoff

new leaders

In advance of the spinoff of its Mission Technology Solutions unit, Houston-based KBR has made two C-suite hires for the new business.

Michael LaRouche is coming aboard as president and CEO of the spinoff, currently called SpinCo, on Sept. 26. Nicholas Veasey is joining as executive vice president and chief financial officer on July 1.

“Michael and Nick bring a highly complementary combination of operational leadership, financial expertise, and mission-driven experience, and together they will accelerate our impact for stakeholders,” Stuart Bradie, chairman, president and CEO of publicly traded KBR, said in a news release.

LaRouche currently is CEO of Serco North America, a Herndon, Virginia-based government services contractor. Veasey most recently was CFO of MAG Aerospace, a Fairfax, Virginia-based defense contractor.

SpinCo, a government services contractor, will launch with more than $5.3 billion in annual revenue and 20,000 employees. KBR’s total headcount is around 36,000. Branding for SpinCo, including a formal name, will be revealed in July.

“SpinCo is positioned as a top-tier provider of differentiated technology solutions, anchored by deep mission expertise, global scale, and a relentless commitment to delivering for our customers,” LaRouche says.

After the spinoff, the slimmed-down KBR will focus on its Sustainable Technology Solutions business, a provider of energy and industrial technology that generated $2.5 billion in revenue in 2025. Bradie will remain chairman, president and CEO of the business.

Both SpinCo and the new KBR will be public companies. The spinoff is scheduled to be completed in January.
