Houston climatech company Gold H2 completed its first field trial that demonstrates subsurface bio-stimulated hydrogen production, which leverages microbiology and existing infrastructure to produce clean hydrogen.

Gold H2 is a spinoff of another Houston biotech company, Cemvita.

“When we compare our tech to the rest of the stack, I think we blow the competition out of the water," Prabhdeep Singh Sekhon, CEO of Gold H2 Sekhon previously told Energy Capital.

The project represented the first-of-its-kind application of Gold H2’s proprietary biotechnology, which generates hydrogen from depleted oil reservoirs, eliminating the need for new drilling, electrolysis or energy-intensive surface facilities. The Woodlands-based ChampionX LLC served as the oilfield services provider, and the trial was conducted in an oilfield in California’s San Joaquin Basin.

According to the company, Gold H2’s technology could yield up to 250 billion kilograms of low-carbon hydrogen, which is estimated to provide enough clean power to Los Angeles for over 50 years and avoid roughly 1 billion metric tons of CO2 equivalent.

“This field trial is tangible proof. We’ve taken a climate liability and turned it into a scalable, low-cost hydrogen solution,” Sekhon said in a news release. “It’s a new blueprint for decarbonization, built for speed, affordability, and global impact.”

Highlights of the trial include:

  • First-ever demonstration of biologically stimulated hydrogen generation at commercial field scale with unprecedented results of 40 percent H2 in the gas stream.
  • Demonstrated how end-of-life oilfield liabilities can be repurposed into hydrogen-producing assets.
  • The trial achieved 400,000 ppm of hydrogen in produced gases, which, according to the company,y is an “unprecedented concentration for a huff-and-puff style operation and a strong indicator of just how robust the process can perform under real-world conditions.”
  • The field trial marked readiness for commercial deployment with targeted hydrogen production costs below $0.50/kg.

“This breakthrough isn’t just a step forward, it’s a leap toward climate impact at scale,” Jillian Evanko, CEO and president at Chart Industries Inc., Gold H2 investor and advisor, added in the release. “By turning depleted oil fields into clean hydrogen generators, Gold H2 has provided a roadmap to produce low-cost, low-carbon energy using the very infrastructure that powered the last century. This changes the game for how the world can decarbonize heavy industry, power grids, and economies, faster and more affordably than we ever thought possible.”

Houston geothermal exec shares why she sees the potential of geothermal power

the view from heti

Houston-based Fervo Energy, the leader in enhanced geothermal technology, is accelerating decarbonization by bringing 24/7 carbon-free electricity to the grid.

Fervo’s mission is to leverage geoscience innovations to accelerate the world’s transition to sustainable energy. Fervo continues to demonstrate the commercial viability and scalability of enhanced geothermal energy, which uses breakthrough techniques to harness heat from the earth and generate continuous electricity.

Sarah Jewett, VP of Strategy at Fervo, shared more about how Fervo has been able to leverage proven oil and gas technologies, such as horizontal drilling, well stimulation, and fiber-optic sensing, to pave the way toward a low-carbon energy future.

Q: Can you share your background and tell us a little about your career prior to joining Fervo Energy?

I’m a mechanical engineer by training. My career started in oil field services after working internships in hydropower and wind power. Transition technologies, such as enhanced geothermal systems, require a wide range of technical and operational innovations. When I joined Fervo Energy, I knew I was with the right team to accomplish the massive mission of addressing climate change.

Q: What are some of the challenges Fervo encounters as a carbon-free energy company?

There are a lot of misperceptions around the geothermal industry. Traditional geothermal wells require highly specific subsurface conditions—the right heat, fluid saturation, and permeability. Because of this, it has been challenging to scale geothermal energy.

Our enhanced geothermal technology is a game changer, but our technical demonstrations are capital intensive. So, one of our biggest ongoing challenges is to execute our projects flawlessly, building a new reputation centered around scalability and affordability.

In addition, when we started, we faced a somewhat uncertain market. Today, as companies look for innovative ways to decarbonize operations, geothermal has become one of the hottest renewables on the market.

Q: You’re now in your seventh year as a company. What are some of the major milestones that have contributed to the success of the business?

Fervo recently completed the 30-day well test on Project Red, a first-of-its-kind geothermal pilot project, located in northern Nevada. We confirmed record production of 24/7 carbon-free enhanced geothermal energy, which established Project Red as the most productive enhanced geothermal system in history.

This success validated the commercial viability of Fervo’s geothermal well construction and monitoring technologies, which leverage drilling and production innovations from modern oil and gas development. Since then, we’ve broken ground on our Cape Station project, a near-field development in southwest Utah that is set to deliver 400 MW of power by 2028.

Q: Tell us about your vision for the future. What is Fervo Energy focused on in 2024?

We’re ushering in a new era of geothermal energy. Our approach to enhanced geothermal energy is no longer a theoretical concept—it’s a proven solution for meeting the world’s growing demand for sustainable energy. We’re building modular power facilities and we’re able to scale them quickly. In 2024, we’re focused on finding the capital we need to achieve the scale we want. That will be key to unlocking much more growth.

Oxy CEO Vicki Hollub to retire, Reuters reports

retirement plans

Vicki Hollub, CEO of Houston-based Occidental (Oxy), is set to retire this year, Reuters first reported Thursday.

Hollub has held the top leadership position at Oxy since 2016 and has been with the oil and gas giant for more than 40 years. Before being named CEO, she served as chief operating officer and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Reuters reports that a firm date for her retirement has not been set. Richard Jackson, who currently serves as Oxy's COO, is expected to replace Hollub in the CEO role.

Oxy is leading a number of energy transition projects.

It's subsidiary 1PointFive is developing a $1.3 billion direct air capture (DAC) project in the Midland-Odessa area that is slated to be the largest facility of its kind in the world. Known as STRATOS, it's designed to capture up to 500,000 metric tons of CO2 per year.

The company shared recently that Phase 1 of the project is expected to go online in Q2, with Phase 2 ramping up through the remainder of 2026.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos last year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” she added.

Oxy was one of the first to set ambitious net-zero goals. In a 2020 interview during CERAWeek, Hollub outlined Oxy's future as a “carbon management company.”

“Ultimately, I don’t know how many years from now, Occidental becomes a carbon management company, and our oil and gas would be a support business unit for the management of that carbon. We would be not only using [CO2] in oil reservoirs [but] capturing it for sequestration as well,” Hollub said.

Oxy opened its Oxy Innovation Center in the Ion last year, focused on advancing low-carbon technology. It also operates Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others.

Hertha Metals named world's  No. 1 most innovative manufacturing co. of 2026

top innovators

Led by Conroe-based Hertha Metals, five organizations in the Houston area earned shoutouts on Fast Company’s list of the World’s Most Innovative Companies of 2026.

Hertha Metals ranked No. 1 in the manufacturing category.

Last year, Hertha unveiled a single-step process for steelmaking that it says is cheaper, more energy-efficient and just as scalable as traditional steel manufacturing. It started testing the process in 2024 at a one-metric-ton-per-day pilot plant.

At the same time, Hertha announced more than $17 million in venture capital funding from investors such as Breakthrough Energy, Clean Energy Ventures, Khosla Ventures, and Pear VC.

“We’re not just reinventing steelmaking; we’re redefining what’s possible in materials, manufacturing, and national resilience,” Laureen Meroueh, founder and CEO of Hertha, said at the time.

Meroueh was also recently named to Inc. Magazine's 2026 Female Founders 500 list.

Hertha, founded in 2022, says traditional steelmaking relies on an outdated, coal-based multistep process that is costly, and contributes up to 9 percent of industrial energy use and 10 percent of global carbon emissions.

By contrast, Hertha’s method converts low-grade iron ore into molten steel or high-purity iron in one step. The company says its process is 30 percent more energy-efficient than traditional steelmaking and costs less than producing steel in China.

Last year, Hertha said it planned to break ground in 2026 on a plant capable of producing more than 9,000 metric tons of steel per year. In its next phase, the company plans to operate at 500,000 metric tons of steel production per year.

Here are Fast Company’s rankings for the four other Houston-area organizations:

  • Houston-based Vaulted Deep, No. 3 in catchall “other” category.
  • XGS Energy, No. 7 in the energy category. XGS’ proprietary solid-state geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock is located. While Fast Company lists Houston as XGS’ headquarters, and the company has a major presence in the city, XGS is based in Palo Alto, California.
  • Houston-based residential real estate brokerage Epique Realty, No. 10 in the business services category. Epique, which bills itself as the industry’s first AI brokerage, provides a free AI toolkit for real estate agents to enhance marketing, streamline content creation, and improve engagement with clients and prospects.
  • Texas A&M University’s Nanostructured Materials Lab in College Station. The lab studies nano-structured materials to make materials lighter for the aerospace industry, improve energy storage, and enable the creation of “smart” textiles.
