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.
