Electrification and automation company ABB, whose U.S. headquarters for its Energy Industries business is in Houston, has tentatively agreed to supply power for a $10 billion hydrogen project in South Texas.

Under a new memorandum of understanding, ABB plans to collaborate with Houston-based Green Hydrogen International on the Hydrogen City project. The first phase of the project is expected to generate 280,000 tons of green hydrogen per year. This green hydrogen will then be converted to one million tons of green ammonia each year.

“Together, we will enable efforts to decarbonize global industry and progress towards a net-zero future,” Brandon Spencer, president of ABB Energy Industries, says in a news release.

The memorandum of understanding calls for ABB’s technology to be assessed for delivery of solar and onshore wind energy to the 2.2-gigawatt electrolyzer facility at Hydrogen City.

The project will store up to 24,000 tons of green hydrogen in underground salt caverns. A 75-mile pipeline to the nearby Corpus Christi energy port will carry the green hydrogen to an ammonia production facility. At this facility, green hydrogen will be turned into green ammonia that’ll be shipped to Europe and Asia.

Green Hydrogen International is in talks with companies interested in using green hydrogen from Hydrogen City as feedstock for sustainable aviation fuel and e-methane.

Hydrogen City will serve a global green ammonia market whose value is projected to reach $17.9 billion by 2030. Construction on Hydrogen City is scheduled to start in 2026, with initial production set for 2030.

Green Hydrogen International unveiled the multiphase Hydrogen City project in 2022, saying it would be “the world’s largest green hydrogen production and storage hub.” At his month’s CERAWeek in Houston, officials provided an update on Hydrogen City.

“Ammonia has the potential to support decarbonization efforts as part of the energy transition through its use as an alternative fuel for heavy transport such as shipping, as well as its current major use in fertilizer production,” ABB says in the news release.

Last October, Green Hydrogen International announced a Hydrogen City partnership with Japanese oil and gas giant Inpex, whose U.S. outpost is in Houston.

Japanese company opts into joint initiative for green hydrogen, ammonia project in South Texas

hydrogen city, Texas

An oil and gas exploration and production company has signed on to collaborate on a green hydrogen project in Texas to keep up with growing global market demand.

INPEX Corp. and Green Hydrogen International have agreed to a Joint Study Agreement to advance a South Texas hydrogen production facility called "Hydrogen City." The project's first phase will produce 280,000 tons per year of green hydrogen and 1 million tons per year of green ammonia. Construction is slated to begin in 2026 with commercial operation expected in 2029.

INPEX's "unparalleled expertise in large energy project development combined with a world-class marketing organization will provide enormous advantages to the Hydrogen City project and our goal of producing the world's lowest-cost green hydrogen by 2029," Brian Maxwell, CEO of GHI, says in a news release.

The partnership brings together both entities' expertise, with INPEX's experience developing large scale energy projects and marketing LNG to international customers. Meanwhile, GHI uses salt cavern storage and behind-the-meter renewable power to produce low-cost green hydrogen.

"I am excited to announce this green hydrogen project in Texas, which exemplifies our unwavering commitment to environmental leadership and innovation," INPEX Representative Director, President, and CEO Takayuki Ueda says in the release. "INPEX's dedication to a brighter, greener future remains steadfast, and this endeavor in Texas marks a pivotal step in our vision for a more sustainable tomorrow."

INPEX is also a part of a large-scale, low-carbon ammonia production and export project on the Houston Ship Channel that was anounced ealier this month.

Hydrogen City, located in South Texas atop the Peidras Pintas Salt Dome, was originally announced in March 2022. There will be a 75 mile pipeline from Hydrogen City to Corpus Christi, supplying a 1 Million Tonne Per Annum (MTPA) ammonia production facility and local off-takers.

8 Houston energy companies land on Time's top greentech list for 2025

top honor

The accolades keep rolling in for Houston-based Fervo Energy, a producer of geothermal power.

Fervo lands at No. 6 on Time magazine and Statista’s new list of America’s Top GreenTech Companies of 2025. The ranking recognizes sustainability-focused companies based on factors such as impact, financial strength, and innovation.

Time notes that Fervo broke ground in 2023 in Utah on what the company claims will be the world’s largest geothermal plant. The plant is scheduled to start supplying carbon-free electricity to the grid next year and to reach its 400-megawatt capacity in three years.

“Technologies like this only make a difference if we deploy them at large-scale in a way that can reduce carbon emissions and increase the reliability of the grid,” Fervo CEO Tim Latimer told Time in 2023.

The startup was named North American Company of the Year by research and consulting firm Cleantech Group for 2025. Fervo topped the Global Cleantech 100, Cleantech Group’s annual list of the world’s most innovative and promising cleantech companies.

Last year, Fervo also made Time’s list of the 200 Best Inventions of 2024. Fervo was recognized in the green energy category for its FervoFlex geothermal power system.

Founded in 2017, Fervo is now a unicorn, meaning its valuation as a private company exceeds $1 billion. The startup’s valuation is estimated at $1.4 billion. According to PitchBook data, the company raised $634 million in the fourth quarter of 2024.

In all, eight Houston-area companies appear among the top 250 greentech companies ranked by Time and Statista. Other than Fervo, they are:

  • No. 43 Lancium Technologies, an energy storage and distribution company
  • No. 50 Solugen, a producer of sustainable chemicals.
  • No. 56 Quaise Energy, which specializes in terawatt-scale geothermal power.
  • No. 129 Plus Power, a developer, owner and operator of battery storage projects.
  • No. 218 Dream Harvest, which promotes sustainable vertical farming.
  • No. 225 Cemvita, which uses synthetic biology to convert carbon emissions into bio-based chemicals.
  • No. 226 Syzygy Plasmonics, which decarbonizes chemical production.
Vermont-based BETA Technologies claimed the No. 1 spot. The company manufactures electric aircraft.
