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.

Will 2023 be hydrogen’s year?

GUEST COLUMN

Yes and no.

Yes, because there is real money, and action, behind it.

Globally, there are 600 projects on the books to build electrolyzers, which separate the oxygen and hydrogen in water, and are critical to creating low-emissions “green hydrogen.” That investment could drive down the cost of low-emissions hydrogen, making it cost competitive with conventional fuels—a major obstacle to its development so far.

In addition, oil companies are interested, too. The industry already uses hydrogen for refining; many see hydrogen as supplemental to their existing operations and perhaps, eventually, supplanting them. In the meantime, it helps them to decarbonize their refining and petrochemical operations, which most of the majors have committed to doing.

Indeed, hydrocarbon-based companies and economies could have a big opportunity in “blue hydrogen,” which uses fossil fuels for production, but then captures and stores emissions. (“Green hydrogen” uses renewables; because it is expensive to produce, it is more distant than blue. “Gray hydrogen” uses fossil fuels, without carbon capture; this accounts for most current production and use.) Oil and gas companies have a head start on related infrastructure, such as pipelines and carbon capture, and also see new business opportunities, such as low-carbon ammonia.

Houston, for example, which likes to call itself the "energy capital of the world,” is going big on hydrogen. The region is well suited to this. It has an extensive pipeline infrastructure, an excellent port system, a pro-business culture, and experience. The Greater Houston Partnership and McKinsey—both of whom I am associated with—estimate that demand for hydrogen will grow 6 to 8 percent a year from 2030 to 2050. No wonder Houston wants a piece of that action.

There are promising, near-term applications for hydrogen, such as ammonia, cement, and steel production, shipping, long-term energy storage, long-haul trucking, and aviation. These bits and pieces add up: steel alone accounts for about 8 percent of global carbon-dioxide emissions. Late last year, Airbus announced it is developing a hydrogen-powered fuel cell engine as part of its effort to build zero-emission aircraft. And Cummins, a US-based engine company, is investing serious money in hydrogen for trains and commercial and industrial vehicles, where batteries are less effective; it already has more than 500 electrolyzers at work.

Then there is recent US legislation. The Infrastructure, Investment and Jobs Act (IIJA) of 2021 allocated $9.5 billion funding for hydrogen. Much more important, though, was last year’s Inflation Reduction Act, which contains generous tax credits to promote hydrogen production. The idea is to narrow the price gap between clean hydrogen and other, more emissions-intensive technologies; in effect, the law seeks to fundamentally change the economics of hydrogen and could be a true game-changer.

This is not without controversy: some Europeans think this money constitutes subsidies that are not allowed under trade rules. For its part, Europe has the hydrogen bug, too. Its REPowerEU plan is based on the idea of “hydrogen-ready infrastructure,” so that natural gas projects can be converted to hydrogen when the technology and economics make sense.

So there is a lot of momentum behind hydrogen, bolstered by the ambitious goals agreed to at the most recent climate conference in Egypt. McKinsey estimates that hydrogen demand could reach 660 million tons by 2050, which could abate 20 percent of total emissions. Total planned production for lower-emission green and blue hydrogen through 2030 has reached more than 26 million metric tons annually—quadruple that of 2020.

No, because major issues have not been figured out.

The plans in the works, while ambitious, are murky. A European official, asked about the REPowerEU strategy, admitted that “it’s not clear how it will work.” The same can be said of the United States. The hydrogen value chain, particularly for green hydrogen, requires a lot of electricity, and that calls for flexible grids and much greater capacity. For the United States to reach its climate goals, the grid needs to grow an estimated 60 percent by 2030.That is not easy: just try siting new transmission lines and watch the NIMBY monsters emerge.

Permitting can be a nightmare, often requiring separate approvals from local, state, interstate, and federal authorities, and from different authorities for each (air, land, water, endangered species, and on and on); money does not solve this. Even a state like Texas, which isn’t allergic to fossil fuels and has a relatively light regulatory touch, can get stuck in permitting limbo. Bill Gates recently noted that “over 1,000 gigawatts worth of potential clean energy projects [in the United States] are waiting for approval—about the current size of the entire U.S. grid—and the primary reason for the bottleneck is the lack of transmission.”

Then there is the matter of moving hydrogen from production site to market. Pipeline networks are not yet in place and shifting natural gas pipelines to hydrogen is a long way off. Liquifying hydrogen and transporting is expensive. In general, because hydrogen is still a new industry, it faces “chicken or egg” problems that are typical of the difficulties big innovations face, such as connecting hydrogen buyers to hydrogen producers and connecting carbon emitters to places to store the carbon dioxide. These challenges add to the complexity of getting projects financed.

Finally, there is money. McKinsey estimates that getting on track to that 600 million tons would require investment of $950 billion by 2030; so far, $240 billion has been announced.

Where I stand: in the middle.

I believe in hydrogen’s potential. More than 3 years ago, I wrote about hydrogen, arguing that while there had been real progress, “many things need to happen, in terms of policy, finance, and infrastructure, before it becomes even a medium-sized deal.” Now, some of those things are happening.

So, I guess I land somewhere in the middle. I think 2023 will see real progress, in decarbonizing refining and petrochemicals operations and producing ammonia, specifically. I am also optimistic that a number of low-emissions electrolysis projects will move ahead. And while such advances might seem less than transformative, they are critical: hydrogen, whether blue or green, needs to prove itself, and 2023 could be the year it does.

Because I take hydrogen’s potential seriously, though, I also see the barriers. If it is to become the big deal its supporters believe it could be, that requires big money, strong engineering and construction project management, sustained commitment, and community support. It’s easy to proclaim the wonders of the hydrogen economy; it’s much more difficult to devise sensible business models, standardized contracts, consistent incentives, and a regulatory system that doesn’t drive producers crazy. But all this matters—a lot.

My conclusion: there will be significant steps forward in 2023—but take-off is still years away.

Engie signs deal to supply wind power for Texas data center

wind deal

Houston-based Engie North America, which specializes in generating low-carbon power, has sealed a preliminary deal to supply wind power to a Cipher Mining data center in Texas.

Under the tentative agreement, Cipher could buy as much as 300 megawatts of clean energy from one of Engie’s wind projects. The financial terms of the deal weren’t disclosed.

Cipher Mining develops and operates large data centers for cryptocurrency mining and high-performance computing.

In November, New York City-based Cipher said it bought a 250-acre site in West Texas for a data center with up to 100 megawatts of capacity. Cipher paid $4.1 million for the property.

“By pairing the data center with renewable energy, this strategic collaboration supports the use of surplus energy during periods of excess generation, while enhancing grid stability and reliability,” Engie said in a news release about the Cipher agreement.

The Engie-Cipher deal comes amid the need for more power in Texas due to several factors. The U.S. Energy Information Administration reported in October that data centers and cryptocurrency mining are driving up demand for power in the Lone Star State. Population growth is also putting pressure on the state’s energy supply.

Last year, Engie added 4.2 gigawatts of renewable energy capacity worldwide, bringing the total capacity to 46 gigawatts as of December 31. Also last year, Engie signed a new contract with Meta (Facebook's owner) and expanded its partnership with Google in the U.S. and Belgium.

Houston researchers make headway on developing low-cost sodium-ion batteries

energy storage

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”

ExxonMobil lands major partnership for clean hydrogen facility in Baytown

power deal

Exxon Mobil and Japanese import/export company Marubeni Corp. have signed a long-term offtake agreement for 250,000 tonnes of low-carbon ammonia per year from ExxonMobil’s forthcoming facility in Baytown, Texas.

“This is another positive step forward for our landmark project,” Barry Engle, president of ExxonMobil Low Carbon Solutions, said in a news release. “By using American-produced natural gas we can boost global energy supply, support Japan’s decarbonization goals and create jobs at home. Our strong relationship with Marubeni sets the stage for delivering low-carbon ammonia from the U.S. to Japan for years to come."

The companies plan to produce low-carbon hydrogen with approximately 98% of CO2 removed and low-carbon ammonia. Marubeni will supply the ammonia mainly to Kobe Power Plant, a subsidiary of Kobe Steel, and has also agreed to acquire an equity stake in ExxonMobil’s low-carbon hydrogen and ammonia facility, which is expected to be one of the largest of its kind.

The Baytown facility aims to produce up to 1 billion cubic feet daily of “virtually carbon-free” hydrogen. It can also produce more than 1 million tons of low-carbon ammonia per year. A final investment decision is expected in 2025 that will be contingent on government policy and necessary regulatory permits, according to the release.

The Kobe Power Plant aims to co-fire low-carbon ammonia with existing fuel, and reduce CO2 emissions by Japan’s fiscal year of 2030. Marubeni also aims to assist the decarbonization of Japan’s power sector and steel manufacturing industry, chemical industry, transportation industry and various others sectors.

“Marubeni will take this first step together with ExxonMobil in the aim of establishing a global low-carbon ammonia supply chain for Japan through the supply of low-carbon ammonia to the Kobe Power Plant,” Yoshiaki Yokota, senior managing executive officer at Marubeni Corp., added in the news release. “Additionally, we aim to collaborate beyond this supply chain and strive towards the launch of a global market for low-carbon ammonia. We hope to continue to actively cooperate with ExxonMobil, with a view of utilizing this experience and relationship we have built to strategically decarbonize our power projects in Japan and Southeast Asia in the near future.”
