Gold H2, a Houston-based producer of clean hydrogen, is teaming up with a major U.S.-based oil and gas company as the first step in launching a 12-month series of pilot projects.

The tentative agreement with the unnamed oil and gas company kicks off the availability of the startup’s Black 2 Gold microbial technology. The technology underpins the startup’s biotech process for converting crude oil into proprietary Gold Hydrogen.

The cleantech startup plans to sign up several oil and gas companies for the pilot program. Gold H2 says it’s been in discussions with companies in North America, Latin America, India, Eastern Europe and the Middle East.

The pilot program is aimed at demonstrating how Gold H2’s technology can transform old oil wells into hydrogen-generating assets. Gold H2, a spinout of Houston-based biotech company Cemvita, says the technology is capable of producing hydrogen that’s cheaper and cleaner than ever before.

“This business model will reshape the traditional oil and gas industry landscape by further accelerating the clean energy transition and creating new economic opportunities in areas that were previously dismissed as unviable,” Gold H2 says in a news release.

The start of the Black 2 Gold demonstrations follows the recent hiring of oil and gas industry veteran Prabhdeep Singh Sekhon as CEO.

“With the proliferation of AI, growth of data centers, and a national boom in industrial manufacturing underway, affordable … carbon-free energy is more paramount than ever,” says Rayyan Islam, co-founder and general partner at venture capital firm 8090 Industries, an investor in Gold H2. “We’re investing in Gold H2, as we know they’ll play a pivotal role in unleashing a new dawn for energy abundance in partnership with the oil industry.”

Newly named CEO to lead Houston gold hydrogen biotech co. into high-growth phase

HOUSTON INNOVATORS PODCAST EPISODE 239

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."

Houston biotech company expands as a network of startups with energy transition solutions

HOUSTON INNOVATORS PODCAST EPISODE 217

A lot has changed since Moji Karimi co-founded his biotech company Cemvita with his sister Tara in 2017. In fact, a lot has changed just in 2023 — for Cemvita, for the energy transition, and for world as a whole.

In the past year, Cemvita has evolved its business to target three verticals, all within the company's mission of using synthetic biology to create solutions for the energy transition. Now, as Karimi explains on the Houston Innovators Podcast, Cemvita is a startup of startups.

Its eCO2 business line targets carbon dioxide utilization for feedstock, the technology's legacy application. But this year, Cemvita spun out its gold hydrogen arm into Gold H2, which has celebrated a successful pilot in the Permian Basin and raised early-stage funding. Cemvita has another vertical, a resource mining operation — under its Endolith spinoff — that operates out of a satellite office in Colorado.

While tackling the various verticals might seem ambitious, Karimi explains that they are all aligned with Cemvita's core mission and technology.

"If you think about it, everything we're doing has something to do with nature," he says on the show. "Environmental microbiology, biotech, and synthetic biology — it's now available, and we have the tools to do it. We want to be the company that goes and finds those applications and translates it from the idea and the science to the technology, and then scale it up into the engineer solution."



The way Cemvita is doing it is through partnerships. Karimi says he doesn't care about his logo being on the side of his plant, rather that a company can take the technology and apply it on a greater scale.

"The core of what we do is collaboration," he says. "What we care about is for the solutions to come to life."

Cemvita has a longstanding partnership with Oxy, first as an early investor in 2019, and later committing to establishing a plant around Cemvita's CO2-converting tech. Similarly, United Airlines invested in Cemvita before securing a massive offtake agreement with the airline for sustainable aviation fuel.

On the podcast, Karimi share some of his advice and observations on tackling startup-corporate relationships, as well as how these partnerships will continue in the new year. Karimi described 2023 as a year of resiliency, and he has big plans to deliver on for 2024.

"This next year is all about focused execution," he says, noting specifically a pre-commercial demo plant for CO2 utilization, a gold hydrogen field trial to prove out tech for Gold H2, and ongoing speed column tests for Endolith.

"We're graduating from the startup phase," Karimi says. "We need to make sure we don't lose the agility of being a startup."

Houston cleantech company sees shining success with gold hydrogen

bling, bling

Houston-based cleantech startup Cemvita Factory is kicking things into high gear with its Gold Hydrogen product.

After successfully completing a pilot test of Gold Hydrogen in the oil-rich Permian Basin of West Texas, Cemvita has raised an undisclosed amount of funding through its new Gold H2 LLC spin-out. The lead investors are Georgia-based equipment manufacturer Chart Industries and 8090 Industries, an investment consortium with offices in New York City and Los Angeles.

Gold Hydrogen provides carbon-neutral hydrogen obtained from depleted oil and gas wells. This is achieved through bioengineering subsurface microbes in the wells to consume carbon and generate clean hydrogen.

Cemvita says it set up Gold H2 to commercialize the business via licensing, joint ventures, and outright ownership of hydrogen assets.

“We have incredible conviction in next-generation clean hydrogen production methods that leverage the vast and sprawling existing infrastructure and know-how of the oil and gas industry,” Rayyan Islam, co-founder and general partner of 8090 Industries, says in a news release.

Traditional methods of producing hydrogen without greenhouse gas emissions include electrolysis powered by renewable sources like wind, solar or water, according to Cemvita. However, production of green hydrogen through normal avenues eats up a lot of energy and money, the startup says.

By contrast, Cemvita relies on depleted oil and gas wells to cheaply produce carbon-free hydrogen.

“The commercialization and economics of the hydrogen economy will require technologies that produce the hydrogen molecule at a meaningful scale with no carbon emissions. Gold H2 is leading the charge … ,” says Jill Evanko, president and CEO of Chart Industries.

Investors in Cemvita include Oxy Low Carbon Ventures, an investment arm of Houston-based Occidental Petroleum, as well as BHP Group, Mitsubishi, and United Airlines Ventures.

Oxy Low Carbon Ventures and United Airlines Ventures are financing Cemvita’s work on sustainable jet fuel. United Airlines operates a hub at George Bush Intercontinental Airport Houston.

Founded by brother-and-sister team Moji and Tara Karimi in 2017, Cemvita uses synthetic biology to turn carbon dioxide into chemicals and alternative fuels.

Air taxi network to land in 'Texas triangle' of Houston, Austin, DFW next year

taking flight

San Jose, California-based aerospace company Archer Aviation is bringing its air-taxi system to the “Texas triangle” of Houston, Austin and Dallas-Fort Worth.

Currently, the planned zero-emission electric air taxi networks will use Archer’s Midnight air taxi to “turn 60- to 90-minute drives to major airports, business districts and major destinations into 10- to 20-minute flights,” the company said in a news release. Archer plans to begin flights in the Texas triangle next year.

The Midnight air taxi is an all-electric vertical takeoff and landing (eVTOL) aircraft. It can carry four passengers and a pilot and is designed for consecutive flights of about 20 miles.

Archer cites the Texas triangle as one of the busiest and fastest-growing “megaregions” in the country due to its proximity to coastal regions, major airports, and a number of business districts.

Archer Chief Commercial Officer Nikhil Goel described the air taxi experience to CW Houston as “100 times quieter than a helicopter for the price of an Uber Black.” He added that the air taxis are a combination of a helicopter, a small airplane and a drone.

In Houston, Archer’s air taxi network will aim to connect George Bush Intercontinental, William P. Hobby and Sugar Land Regional Airport with downtown destinations, including the Thompson Hotel helipad, and Galveston.

In Austin, it plans to link the city's Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas. Archer debuted its Midnight aircraft at the F1 Prix in the Fan Zone and the F1 Paddock at Austin’s Circuit of the Americas. The Dallas-Fort Worth network is slated to include Dallas-Fort Worth International Airport, Dallas Love Field, Addison Airport, Arlington Municipal Airport, Fort Worth Meacham International Airport and Perot Field Fort Worth Alliance Airport, plus major business hubs like Frisco Station.

“Texas is setting the bar for America’s leadership in the next generation of aviation,” Adam Goldstein, founder and CEO of Archer Aviation, said in the release. “Our planned networks will make the benefits of electric air taxis real for Texans — trading hours in traffic for minutes in the air, while connecting the biggest airports, business districts and sporting hubs in ways that America’s largest megaregion needs to grow.”

Archer is working with state and local partners to develop charging infrastructure and plans to pursue Texas operations through the White House’s eVTOL Integration Pilot Program, according to the release. It recently completed its "No Roads" flight tour, which included multiple flights over the San Francisco Bay, and flew to seven cities over three days.

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.
