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.”

Hydrogen industry could have major impact on Texas water resources, study says

Just as the data center industry thrives on electricity, the hydrogen industry thrives on water.

A new study from researchers at the University of Texas at Austin found that by 2050, new hydrogen production facilities could account for 2 percent to nearly 7 percent of water demand in the state. The impact could be especially dramatic along the Gulf Coast, where most of the state’s hydrogen production facilities are already built or are being planned.

The research was published in the journal Sustainability.

The study reported that "most existing and proposed hydrogen production infrastructures are within projected water-strained cities and counties, such as Houston in Harris County and Corpus Christi in Nueces County."

Compared with municipal water supplies or irrigation systems, the hydrogen industry’s demand for water is comparatively small, the study’s lead author, Ning Lin, an energy economist at UT’s Bureau of Economic Geology, said in a news release. But hydrogen-fueled demand could strain communities that already are grappling with current and future water shortages.

“Where you put a project can make a huge difference locally,” Lin says. “With multiple hydrogen facilities planned in water-stressed Gulf Coast counties, this study highlights the urgent need for integrated water and energy planning and provides a solid foundation to help policymakers, industry, and communities make informed decisions about hydrogen and water management.”

To forecast water demand, Lin and her colleagues crunched data from a 2024 National Petroleum Council study that estimated the regional hydrogen demand from 2030 to 2050 based on two energy policy scenarios.

As part of the study, researchers reviewed water use and water quality for various hydrogen production methods that affect whether water remaining from production can be recycled.

“In order to plan for water needs, somebody has to figure out what those future demands might look like, and this paper puts some numbers to (it) that, I think, will be very helpful,” Robert Mace, executive director of the Meadows Center for Water and the Environment at Texas State University, who was not part of the study, added in the release.

Houston researchers develop catalyst for emission-free hydrogen production using light instead of heat

switch flipped

Researchers at Rice University have developed a catalyst that could render steam methane reforming, or SMR, entirely emission-free by using light rather than heat to drive the reaction.

The researchers believe the work could prove to be a breakthrough for extending catalyst lifetimes. This will improve efficiencies and reduce costs for a number of industrial processes that are affected by a form of carbon buildup that can deactivate catalysts called coking.

The new copper-rhodium photocatalyst uses an antenna-reactor design. When it is exposed to a specific wavelength of light it breaks down methane and water vapor without external heating into hydrogen and carbon monoxide. The importance of this is it is a chemical industry feedstock that is not a greenhouse gas. Rice’s work also shows that the antenna-reactor technology can overcome catalyst deactivation due to oxidation and coking by employing hot carriers to remove oxygen species and carbon deposits, which effectively regenerates the catalyst with light.

The new SMR reaction pathway build off a 2011 discovery from Peter Nordlander, Rice’s Wiess Chair and Professor of Physics and Astronomy and professor of electrical and computer engineering and materials science and nanoengineering, and Naomi Halas. They are the authors on the study about the research that was published in Nature Catalysis. The study showed that the collective oscillations of electrons that occur when metal nanoparticles are exposed to light can emit “hot carriers” or high-energy electrons and holes that can be used to drive chemical reactions.

“This is one of our most impactful findings so far, because it offers an improved alternative to what is arguably the most important chemical reaction for modern society,” Norlander says in a news release.

The research was supported by Robert A. Welch Foundation (C-1220, C-1222) and the Air Force Office of Scientific Research (FA9550-15-1-0022) with the Shared Equipment Authority at Rice providing data analysis support.

“This research showcases the potential for innovative photochemistry to reshape critical industrial processes, moving us closer to an environmentally sustainable energy future,” Halas adds.

Hydrogen has been studied as it could assist with the transition to a sustainable energy ecosystem, but the chemical process responsible for more than half of the current global hydrogen production is a substantial source of greenhouse gas emissions.Hydrogen is produced in large facilities that require the gas to be transported to its point of use. Light-driven SMR allows for on-demand hydrogen generation,which researchers believe is a key benefit for use in mobility-related applications like hydrogen fueling stations or and possibly vehicles.

Houston company scores agreement to work on Canadian green hydrogen project

contract secured

Houston-headquartered McDermott has reported that it secured an agreement to work on Canada's first commercial green hydrogen and ammonia production facility.

The Early Contractor Involvement agreement is from Abraxas Power Corp. to work on the Exploits Valley Renewable Energy Corporation (EVREC) project located in Central Newfoundland and will include developing a wind farm with up to 530 turbines that will have the ability to generate 3.5 gigawatts of electricity and 150 megawatts solar photo voltaic. Additionally, the facility, once completed, will be able to produce 165 kilo tons per Annum of hydrogen and 5,000 metric tons per day of ammonia.

"The agreement is testament to McDermott's industry-leading delivery and installation expertise, and the breadth of our capabilities across the energy transition," Rob Shaul, McDermott's senior vice president, Low Carbon Solutions, says in a news release. "Our century of experience, from concept to completion, and integrated delivery model, means we can offer Abraxas a repeatable modular implementation solution that is expected to drive cost savings, reduce risk and provide quality assurance."

Per the agreement, the company will provide front-end engineering design, engineering, procurement, and construction execution planning services, and more for the project. According to McDermott, the company's contribution to the project will be led from McDermott's Houston office with support from its office in India.

Recently, another collaboration McDermott is working on reached a new milestone. Houston-based Element Fuels has completed the pre-construction phase of its hydrogen-powered clean fuels refinery and combined-cycle power plant in the Port of Brownsville. McDermott is providing front-end engineering design services for the project.

In October, McDermott announced that it signed a lighthouse agreement with United Kingdom-based industrial software company AVEVA and Massachusetts-based product lifecycle management platform provider Aras. With the new software, McDermott plans "to develop its asset lifecycle management capability across the energy transition, oil and gas, and nuclear sectors," per the news release.

Texas hydrogen research hub brings on new corporate partner

howdy, partner

A Texas US Department of Energy initiative has added a new corporate player.

Hitachi Energy has joined the DOE's H2@Scale in Texas and Beyond initiative with GTI Energy, Frontier Energy, The University of Texas Austin, and others. The initiative, which opened earlier this year, plans to assist in “integrating utility-scale renewable energy sources with power grids and managing and orchestrating a variety of energy sources” according to a news release.

Most of the ‘H2@Scale project’s activities take place at University of Texas JJ Pickle Research Center in Austin. The project is part of a larger one to expand hydrogen’s role and help to decarbonize Texas. The ‘H2@Scale' project consists of multiple hydrogen production options like a vehicle refueling station alongside a fleet of hydrogen fuel cell vehicles.

Overall, the project is one of the largest collections of renewable hydrogen production, onsite storage, and end-use technologies that are all located at the same site.

Another larger goal is to investigate the efficiency and cost-effectiveness of hydrogen generation from renewable resources, which all aligns with the project’s vision of decarbonization efforts.

Hitachi Energy is part of the full hydrogen value chain from early-stage project origination and design. They also work to ensure grid compliance, power conversion systems and asset management solutions.

“Hitachi Energy is proud to be a key partner in the US Department of Energy’s ‘H2@Scale in Texas and Beyond’ project. The initiative comes at a pivotal moment in our commitment to advancing hydrogen production and its role in the evolving clean energy landscape,” Executive Vice President and Region Head of North America at Hitachi Energy Anthony Allard says in a news release. “As hydrogen emerges as a critical element in decarbonizing hard-to-abate industries, Hitachi Energy remains dedicated to drive innovation and sustainability on a global scale.”

Hitachi’s project teams will undertake feasibility studies for scaling up hydrogen production and use, which will aim to benefit the development of a strategic plan and implementation of the H2@Scale project in the Port of Houston and the region of the Gulf Coast. The teams will also seek opportunities to leverage prospective hydrogen users, pre-existing hydrogen pipelines, and large networks of concentrated industrial infrastructure. Then, they will work to identify environmental and economic benefits of hydrogen deployment in the area.

Earlier this year, Hitachi Energy teamed up with teamed up with Houston-based electrical transmission developer Grid United for a collaboration to work on high-voltage direct current technology for Grid United transmission projects. These projects will aim to interconnect the eastern and western regional power grids in the U.S. The Eastern Interconnection east of the Rocky Mountains, the Western Interconnection west of the Rockies and the Texas Interconnection run by the Electric Reliability Council of Texas, make up the three main power grids.

ExxonMobil extends European fuel cell pilot project

next step

The Esso fuel business of Spring-based ExxonMobil is forging ahead with a pilot project at its Dutch refinery in Rotterdam to test technology aimed at reducing carbon emissions and simultaneously generating electricity and hydrogen.

The pilot project is a cornerstone of an extended agreement between ExxonMobil Technology and Engineering and Danbury, Connecticut-based clean energy company FuelCell Energy. The deal is now set to expire at the end of 2026.

ExxonMobil and FuelCell announced the pilot project in 2023.

“The unique advantage of this technology is that it not only captures CO2 but also produces low-carbon power, heat, and hydrogen as co-products,” Geoff Richardson, senior vice president of ExxonMobil Low Carbon Solutions, said last year.

The Rotterdam facility, which opened in 1960, will be the first location in the world to test the technology. The technology eventually could be rolled out at additional ExxonMobil sites.

The European Union is among the funders of the pilot project. FuelCell is making carbonate fuel cells for the project at its manufacturing plant in Torrington, Connecticut.

The extended agreement enables FuelCell to incorporate elements of the jointly developed technology into carbon capture products currently being marketed to customers. ExxonMobil and FuelCell are working on formalizing an arrangement for selling the new technology.

“The technology, which captures carbon while simultaneously generating electricity and hydrogen, could improve the economics of carbon capture and could potentially lower the barrier to broader adoption of carbon capture in the marketplace,” according to a FuelCell news release.

FuelCell says its 10-year partnership with ExxonMobil has focused on developing technology that reduces carbon emissions from emission-intensive sectors while generating electricity and hydrogen in the process — “something that no other fuel cell technology or conventional absorption systems can do.”
