Using microbes to sustainably unlock low-cost hydrogen sounds like the work of science fiction, but one Houston company is doing just that.

Gold H2, a spin-off company from Cemvita, has bioengineered subsurface microbes to use in wells to consume carbon and generate clean hydrogen. The technology was piloted two years ago by Cemvita, and now, as its own company with a new CEO, it's safe to say Gold H2's on its way.

"First of all, that was groundbreaking," Prabhdeep Singh Sekhon, CEO of Gold H2, says of the 2022 pilot in the Permian Basin, "to be able to use bugs to produce hydrogen within a couple of days."

"2024 is supposed to be the year where Gold H2 takes off," Sekhon, who joined the company in April, tells the Houston Innovators Podcast. "It was one of those opportunities that I couldn't turn down. I had been following the company. I thought, 'here is this innovative tech that's on the verge of providing a ground-breaking solution to the energy transition — what better time to join the team.'"

Sekhon shares on the show how his previous roles at NextEra Energy Resources and Hess have prepared him for Gold H2. Specifically, as a leader on NextEra’s strategy and business development team, he says he was tasked with figuring out what the energy industry looks like in the next five, 10, and 20 years.

"Green hydrogen was a huge buzz, but one of the things I realized when I started looking at green hydrogen was that it's very expensive," Sekhon says. "I wanted to look at alternatives."

This journey led him to what Cemvita was doing with gold hydrogen, Sekhon says, explaining that the ability to use biotechnology to provide a new revenue stream from the mostly used up wells struck him as something with major potential.

"The idea of repurposing existing oil and gas assets to become hydrogen assets, leveraging current infrastructure to drive down overall deliver costs — to me I thought, 'wow, if they can make this works, that's brilliant,'" he says.

Now, as CEO, Sekhon gets to lead the company toward these goals, which include expanding internationally. He explains on the show that Gold H2 is interested in expanding to any part of the world where there's interest in implementing their biotech. In order to support the growth, Sekhon says they are looking to raise funding this year with plans for an additional round, if needed, in 2025.

"When we compare our tech to the rest of the stack, I think we blow the competition out of the water," Sekhon says, explaining that Gold H2's approach to gold hydrogen development is novel when you look at emerging technology in the space. "We're using a biological process — cheap bugs that eat oil for a living."

Rice University researchers unveil new model that could sharpen MRI scans

MRI innovation

Researchers at Rice University, in collaboration with Oak Ridge National Laboratory, have developed a new model that could lead to sharper imaging and safer diagnostics using magnetic resonance imaging, or MRI.

In a study recently published in The Journal of Chemical Physics, the team of researchers showed how they used the Fokker-Planck equation to better understand how water molecules respond to contrast agents in a process known as “relaxation.” Previous models only approximated how water molecules relaxed around contrasting agents. However, through this new model, known as the NMR eigenmodes framework, the research team has uncovered the “full physical equations” to explain the process.

“The concept is similar to how a musical chord consists of many notes,” Thiago Pinheiro, the study’s first author, a Rice doctoral graduate in chemical and biomolecular engineering and postdoctoral researcher in the chemical sciences division at Oak Ridge National Laboratory, said in a news release. “Previous models only captured one or two notes, while ours picks up the full harmony.”

According to Rice, the findings could lead to the development and application of new contrast agents for clearer MRIs in medicine and materials science. Beyond MRIs, the NMR relaxation method could also be applied to other areas like battery design and subsurface fluid flow.

“In the present paper, we developed a comprehensive theory to interpret those previous molecular dynamics simulations and experimental findings,” Dilipkumar Asthagiri, a senior computational biomedical scientist in the National Center for Computational Sciences at Oak Ridge National Laboratory, said in the release. ”The theory, however, is general and can be used to understand NMR relaxation in liquids broadly.”

The team has also made its code available as open source to encourage its adoption and further development by the broader scientific community.

“By better modeling the physics of nuclear magnetic resonance relaxation in liquids, we gain a tool that doesn’t just predict but also explains the phenomenon,” Walter Chapman, a professor of chemical and biomolecular engineering at Rice, added in the release. “That is crucial when lives and technologies depend on accurate scientific understanding.”

The study was backed by The Ken Kennedy Institute, Rice Creative Ventures Fund, Robert A. Welch Foundation and Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory.

Luxury transportation startup connects Houston with Austin and San Antonio

On The Road Again

Houston business and leisure travelers have a luxe new way to hop between Texas cities. Transportation startup Shutto has launched luxury van service connecting San Antonio, Austin, and Houston, offering travelers a comfortable alternative to flying or long-haul rideshare.

Bookings are now available Monday through Saturday with departure times in the morning and evening. One-way fares range from $47-$87, putting Shutto in a similar lane to Dallas-based Vonlane, which also offers routes from Houston to Austin and San Antonio.

Shutto enters the market at a time when highway congestion is a hotter topic than ever. With high-speed rail still years in the future, its model aims to provide fast, predictable service at commuter prices.

The startup touts an on-time departure guarantee and a relaxed, intimate ride. Only 12 passengers fit inside each Mercedes Sprinter van, equipped with Wi-Fi and leather seating. And each route includes a pit stop at roadside favorite Buc-ee's.

In announcing the launch, founder and CEO Alberto Salcedo called the company a new category in Texas mobility.

“We are bringing true disruptive mobility to Texas: faster and more convenient than flying (no security lines, no delays), more comfortable and exclusive than the bus or train, and up to 70 percent cheaper than private transfers or Uber Black,” Salcedo said in a release.

“Whether you’re commuting for business, visiting family, exploring Texas wineries, or doing a taco tour in San Antonio, Shutto makes traveling between these cities as easy and affordable as riding inside the city."

Beyond the scheduled routes, Shutto offers private, customizable trips anywhere in the country, a service it expects will appeal to corporate retreat planners, party planners, and tourists alike.

In Houston, the service picks up and drops off near the Galleria at the Foam Coffee & Kitchen parking lot, 5819 Richmond Ave.. In San Antonio, it is located at La Panadería Bakery’s parking lot at 8305 Broadway. In Austin, the location is the Pershing East Café parking lot at 2501 E. Fifth St.

Houston-area lab grows with focus on mobile diagnostics and predictive medicine

mobile medicine

When it comes to healthcare, access can be a matter of life and death. And for patients in skilled nursing facilities, assisted living or even their own homes, the ability to get timely diagnostic testing is not just a convenience, it’s a necessity.

That’s the problem Principle Health Systems (PHS) set out to solve.

Founded in 2016 in Clear Lake, Texas, PHS began as a conventional laboratory but quickly pivoted to mobile diagnostics, offering everything from core blood work and genetic testing to advanced imaging like ultrasounds, echocardiograms, and X-rays.

“We were approached by a group in a local skilled nursing facility to provide services, and we determined pretty quickly there was a massive need in this area,” says James Dieter, founder, chairman and CEO of PHS. “Turnaround time is imperative. These facilities have an incredibly sick population, and of course, they lack mobility to get the care that they need.”

What makes PHS unique is not only what they do, but where they do it. While they operate one of the largest labs serving skilled nursing facilities in the state, their mobile teams go wherever patients are, whether that’s a nursing home, a private residence or even a correctional facility.

Diagnostics, Dieter says, are at the heart of medical decision-making.

“Seventy to 80 percent of all medical decisions are made from diagnostic results in lab and imaging,” he says. “The diagnostic drives the doctor’s or the provider’s next move. When we recognized a massive slowdown in lab results, we had to innovate to do it faster.”

Innovation at PHS isn’t just about speed; it’s about accessibility and precision.

Chris Light, COO, explains: “For stat testing, we use bedside point-of-care instruments. Our phlebotomists take those into the facilities, test at the bedside, and get results within minutes, rather than waiting days for results to come back from a core lab.”

Scaling a mobile operation across multiple states isn’t simple, but PHS has expanded into nine states, including Texas, Oklahoma, Kansas, Missouri and Arizona. Their model relies on licensed mobile phlebotomists, X-ray technologists and sonographers, all trained to provide high-level care outside traditional hospital settings.

The financial impact for patients is significant. Instead of ambulance rides and ER visits costing thousands, PHS services often cost just a fraction, sometimes only tens or hundreds of dollars.

“Traditionally, without mobile diagnostics, the patient would be loaded into a transportation vehicle, typically an ambulance, and taken to a hospital,” Dieter says. “Our approach is a fraction of the cost but brings care directly to the patients.”

The company has also embraced predictive and personalized medicine, offering genetic tests that guide medication decisions and laboratory tests that predict cognitive decline from conditions like Alzheimer's and Parkinson’s.

“We actively look for complementary services to improve patient outcomes,” Dieter says. “Precision medicine and predictive testing have been a great value-add for our providers.”

Looking to the future, PHS sees mobile healthcare as part of a larger trend toward home-based care.

“There’s an aging population that still lives at home with caretakers,” Dieter explains. “We go into the home every day, whether it’s an apartment, a standalone home, or assisted living. The goal is to meet patients where they are and reduce the need for hospitalization.”

Light highlighted another layer of innovation: predictive guidance.

“We host a lot of data, and labs and imaging drive most treatment decisions,” Light says. “We’re exploring how to deploy diagnostics immediately based on results, eliminating hours of delay and keeping patients healthier longer.”

Ultimately, innovation at PHS isn’t just about technology; it’s about equity.

“There’s an 11-year life expectancy gap between major metro areas and rural Texas,” Dieter says. “Our innovation has been leveling the field, so everyone has access to high-quality diagnostics and care, regardless of where they live.”
