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.

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.

Houston’s data center capacity set to grow 80%, report says

data findings

Houston stands to benefit from constraints dogging data center markets elsewhere in Texas, a new report indicates. This comes against the backdrop of Texas surpassing Virginia as the country’s top state for data centers — and amid deepening opposition to these facilities.

The report, published by commercial real estate services provider JLL, foresees Houston continuing to gain traction in data center development as occupants seek “scalable alternatives” to Texas markets experiencing supply-and-demand imbalances.

The Houston area currently hosts data centers with 287 megawatts of capacity, well below capacity levels in the Dallas-Fort Worth, Austin-San Antonio and West Texas markets.

However, the region is witnessing a spike in capacity, with 390 megawatts of capacity under construction, according to the report. Counting newly built data centers, Houston would be home to 677 megawatts of data center capacity, an 80 percent increase from the current inventory, the report says.

Developers target West Houston for large-scale data centers

Developers increasingly are evaluating West Houston and surrounding areas for large-scale campuses capable of supporting behind-the-meter power, according to the report. Data center development in the region is likely to remain concentrated in those areas, where power is readily accessible and flood risks are lower, the report adds.

The report notes that Houston is evolving from a traditionally enterprise-focused co-location market for data centers into a “credible large-scale growth market,” buoyed by rising interest in hyperscale facilities and increased development activity.

Corporate, energy and healthcare users are still active in Houston’s data center market, the report says, with cloud computing and technology tenants making inroads. The Houston market absorbed 25 megawatts of data center capacity in the first half of this year.

Texas crowned No. 1 state market for data center capacity

The growth of Houston’s data center sector is occurring in tandem with Texas’ ascent as a data center market. The report shows Texas now boasts 26 gigawatts of existing and under-construction capacity, followed by Virginia at 13 gigawatts.

JLL declares that “Texas has cemented its position as the state for data centers.”

The “frontier” markets of West Texas, the Carolinas, Louisiana, and Ohio account for 77 percent of all capacity being developed nationwide, according to the report.

As evidence of Texas’ heightened stature in the data center sector, commercial real estate services provider Cushman & Wakefield recently ranked Dallas as the world’s No. 1 primary data center market, while Austin-San Antonio led the list of second-tier markets and West Texas topped the third-tier ranking.

These rankings underscore “Texas’ growing importance as a large-scale AI infrastructure hub,” Cushman & Wakefield says.

Opposition to new data centers in Texas grows

While businesses see the value of adding data centers in Texas, the state’s data center boom is rattling residents and politicians alike.

A recent University of Houston survey finds that although 85 percent of Houston-area residents use AI—a key driver of data center growth—nearly 63 percent oppose construction of a data center within a mile of their home. Experts estimate 6.5 gigawatts of capacity, or roughly one-fifth of the total U.S. pipeline, will join the Texas power grid by 2030, with Houston serving as a main hub.

A poll taken recently by the University of Texas/Texas Politics Project yielded similar results: 56 percent of Texans oppose development of data centers in their community.

“Texas’ grid is already facing pressure from population growth, extreme weather and rising industrial demand,” UH researcher Soran Mohtadi says. “When residents say they are concerned about data centers, they’re mostly referring to grid reliability and affordability.”

Data center backlash prompts action by politicians

Responding to Texans’ concerns over power and water consumption, Gov. Greg Abbott recently imposed a moratorium on new data centers in the state to allow time for regulatory agencies to assess the projects’ impact. Meanwhile, some state lawmakers are calling for a crackdown on data center development.

Last month, a state legislative committee chaired by Sen. Joan Huffman, a Houston Republican, held a hearing on the effects of state sales tax exemptions given to data centers. The cost of these exemptions has climbed from an estimated $14.6 million in 2014-15 to a projected $3.3 billion in 2028-29, according to law firm Holland & Knight.

Two backers of massive data centers in Texas, social media giant Meta Platforms and AI powerhouse OpenAI, agreed this week to comply with Abbott’s recently issued standards regarding data center projects—and more have followed suit.

Dan Diorio, executive vice president of state policy and government affairs for the industry-backed Data Center Coalition, fears backlash against data centers may curb economic growth in Texas.

“I worry that communities that put moratoriums ultimately create too much uncertainty and unpredictability, and what that ultimately means is that those communities may shut themselves off to data center development but also may shut themselves off to broader economic development,” Diorio told Fox 7 News in Austin.
