As data centers continue to boom throughout Texas, a new report from the Houston Advanced Research Center (HARC) warns that the trend could strain the state’s water supply.

HARC estimates Texas data centers used 25 billion gallons of water in 2025—and that the demand for water will continue to rise to meet the needs of the 464 data centers currently in Texas, as well as 70 additional sites currently under development.

In the report, titled “Thirsty Data and the Lone Star State: The Impact of Data Center Growth on Texas’ Water Supply,” The Woodlands-based nonprofit says that water use for cooling data centers is expected to double or triple by 2028 on the national level. If projections hold, the total annual water use for data centers in Texas will increase by 0.5 percent to 2.7 percent by 2030, or to between 29 billion and 161 billion gallons of water consumed.

Data centers often use water for cooling, though water demand is dependent on the type of cooling used, the size and type of the data center. Although used water can be reused, some new water withdrawals are always needed to replace evaporated water and other systems’ water losses. Water is also used to cool the power plants that generate electricity used by the data centers.

The HARC report offers guidance to address the overall concerns of water demands by data centers, including:

  • Dry cooling methods
  • Increased reliance on wind and solar energy sources
  • Alternative water supplies, like treated wastewater or brackish water for cooling
  • Adjusted operating schedules to accommodate water usage
  • Partnering with local companies to develop projects that reduce water leaks
  • Companies creating their own water infrastructure investments

The report goes on to explain that the Texas State Water Plan, produced by the Texas Water Development Board, projects shortages of 1.6 trillion gallons by 2030 and 2.3 trillion gallons by 2070. HARC posits that the recent surge in water demand from AI data centers is not fully reflected in those projections.

"Texas water plans always look backward, not forward," the report reads. "That means the 2027 water plan, which is in development now, will be based on 2026 regional water plans that do not include forecasted data center water use. Data centers that began operation in 2025 will not be added to the State Water Plan until 2032."

Currently, there are no state regulations that require data centers to report how much water they use. However, the Public Utility Commission of Texas (PUC) plans to survey operators of data centers and cryptocurrency mining facilities on their water consumption, cooling methods and electricity sources this spring. It is expected to release the results by the end of the year. The companies will have six weeks to respond. The Texas Water Development Board will assist the PUCT on the questions.

“I think we all recognize the importance of data centers and the technology they support and what they give to our modern-day life,” PUC Commissioner Courtney Hjaltman said during the last commission meeting. “Texans, regulators and the legislature really need that understanding of data centers, really need to understand the water they’re using so that we can plan and create the Texas we want.”

ExxonMobil expands Gulf Coast CCS business with Louisiana deal

carbon contract

Spring-based energy powerhouse ExxonMobil has picked up another project in the carbon capture and storage (CCS) market.

Natural gas pipeline operator Williams Cos. has tapped ExxonMobil to transport and store up to one metric ton per year of CO2 from Williams’ natural gas collection and processing plant in southwest Louisiana’s Haynesville Shale.

Williams will transport natural gas via its Louisiana Energy Gateway pipeline, then process the natural gas and deliver it to the Gulf Coast for export as liquefied natural gas (LNG). The LNG will be used in power generation, residential and commercial heating, and industrial processes.

Williams recently agreed to acquire Momentum Midstream for up to $5.5 billion to expand Williams’ LNG presence in the Haynesville Shale. Haynesville is the country’s third-largest producer of natural gas.

Once the deal closes, Williams will own a $1.5 billion project in southwest Louisiana that will expand capacity of the Transco natural gas distribution system. The system serves power and LNG-export customers. Williams will also gain over 4,000 miles of pipeline and more than one million acres.

While Williams is based in Tulsa, Oklahoma, it has a significant presence in Houston. Last month, Green Street’s Real Estate Alert reported Williams bought the 64-story, 1.4 million-square-foot Williams Tower south of The Galleria from Invesco Real Estate for more than $300 million. The company will occupy about 360,000 square feet in the skyscraper for its Houston hub.

Williams employs about 800 people in Bayou City, including roughly 700 who work at Williams Tower, and plans to hire another 100 by the end of this year.

The Williams deal is ExxonMobil’s seventh CCS contract. ExxonMobil’s CCS portfolio supports LNG, lower-carbon-intensity steel, ammonia, natural gas processing, industrial gases and methanol.

ExxonMobil has established a “carbon superhighway” along the Gulf Coast to fuel its CCS business. The company owns and operates a more than 1,300-mile CO2 pipeline system, the largest in the U.S.

“Carbon capture is becoming an increasingly important part of industrial operations, but capture alone doesn’t solve the problem of high emissions,” says ExxonMobil. “What matters next is how CO2 is transported, used, and stored.”

ExxonMobil’s CCS initiatives are aimed at capturing a chunk of the rapidly growing CCS market in the U.S. Straits Research forecasts the market will grow from $5.66 billion this year to $13.56 billion by 2034.

“It’s not every day you get to witness the birth of a new American industry, but that’s exactly what’s happening right now at the U.S. Gulf Coast,” Dominic Genetti, senior vice president of CCS at ExxonMobil, wrote in an article published last year on the company’s website.

Fervo Energy, Mercury Fund leaders named first experts in residence for TEX-E

energy mentors

Two leading companies in Houston's clean energy scene have been named the Texas Exchange for Energy & Climate Entrepreneurship's first experts in residence.

TEX-E announced this month that Houston-based geothermal unicorn Fervo Energy and venture capital firm Mercury Fund have joined the nonprofit's new Expert-in-Residence partnership. The program aims to connect TEX-E Fellows with "the people and organizations shaping the future of energy and entrepreneurship."

The 2026 TEX-E Fellows were named in June and include 67 students from six Texas universities and the Massachusetts Institute of Technology. Nineteen are from Houston universities. See the full list here.

Through the Expert-in-Residence program, fellows will be able to network and work with:

"More than anything, students need the determination and creativity to step outside of their comfort zones and tackle problems that lack clear answers. At Fervo, we've consistently bet on young people who lack traditional 'hard skills' but are willing to embrace uncertainty and learn on the job. That open-mindedness will take students far," Jewett said in a prepared statement. Fervo named Jewett as COO in June.

TEX-E was founded in 2022 through partnerships with MIT Martin Trust Center for Entrepreneurship and Greentown Labs. It works with university students from six schools: Rice University, University of Houston, Prairie View A&M University, The University of Texas at Austin, Texas A&M University and MIT.

The organization named Houston venture capital and innovation leader Sandy Guitar as its new executive director last year. Guitar previously served as general partner and managing director at Houston-based VC firm HX Venture Fund and is co-founder of Weathergage Capital.

TEX-E is known for its student track within the Energy Venture Day and Pitch Competition at CERAWeek. It awarded $50,000 to student teams from the University of Texas and Rice University. Read more here.
