breakthrough trial

Gold H2 harvests clean hydrogen from depleted California reservoirs in first field trial

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.”

CPS Energy, which services San Antonio, has agreed to acquire four state-of-the-art natural gas power generation facilities in the Houston area from Missouri-based PROENERGY for $1.387 billion, according to a release.

The recently constructed plants have an aggregate electric capacity of 1,632 megawatts and are located in the Electric Reliability Council of Texas (ERCOT) markets in Harris, Brazoria and Galveston counties. The assets are dual-fuel capable, which would allow CPS Energy to transition to a hydrogen fuel blend and reduce carbon emissions.

CPS president and CEO Rudy Garza said that the acquisition presents a lower cost and lower supply chain risk alternative to building new power facilities while providing reliable, affordable and cleaner energy.

“We are getting the best of both worlds by securing new infrastructure without delay while also strengthening the power supply for our community,” Garza said in a news release. “This acquisition secures reliable capacity today – at a lower cost – and is a win for the customers of CPS Energy, the city of San Antonio and all the communities we serve by meeting their long-term energy needs. As we add resources to meet the needs of our fast-growing communities, we will continue to look to a diverse balance of energy sources that complement our portfolio, including natural gas, solar, wind, and storage, keeping our community powered and growing.”

PROENERGY will continue to staff, operate, and maintain the plants.

“By acquiring recently constructed, currently operating modern power plants that utilize proven technology already in use by CPS Energy, we avoid higher construction costs, inflationary risk, and long timelines associated with building new facilities – while also enhancing the reliability and affordability of the CPS Energy generation portfolio,” Garza added in the release.

CPS Energy is one of the nation’s largest public power, natural gas, and electric companies with 950,000 electric and 389,000 natural gas customers in the San Antonio area and surrounding counties.
